8 GRENZFLÄCHENMATERIALIEN / INTERFACE MATERIALS ENERGIE-MATERIALIEN / ENERGY MATERIALS PROF. DR. VOLKER PRESSER ZUSAMMENFASSUNG Der Programmbereich Energie-Materialien erforscht Materialien und Technologien für eine nachhaltige Energie- und Wasser- nutzung. Hierzu entwickeln wir Materialien, die auf der Nano- ebene Ionen und elektrische Ladung effektiv transportieren und speichern können. Wichtige Elektrodenmaterialien sind nanoporöse Kohlenstoffe, Oxide, Karbide und Sulfide. Einen besonderen Schwerpunkt bilden 2D Materialien, insbesondere MXene. Solche Materialien bilden leistungsstarke Elektroden für Superkondensatoren, Lithium-Ionen oder Natrium-Ionen Batterien zur Energiespeicherung. Die reversible Aufnahme und kontrollierte Abgabe von Ionen ermöglicht auch die Entsalzung von Meerwasser und die Ionentrennung, um Schadstoffe wie Blei abzutrennen oder Wertstoffe wie Lithium wiederzugewin- nen. Für ein umfassendes Verständnis nutzen wir vielfältige Charakterisierungsmethoden, einschließlich In-situ-Verfahren. Wir nutzen verstärkt digitale Methoden zur prädiktiven Mate- rialforschung. Unsere Kollaborationen umfassen sowohl die in- ternationale Grundlagenforschung als auch Industrieprojekte. MISSION The Program Division Energy Materials explores materials and technologies for sustainable energy and water use. To this end, we are developing ma- terials that can effectively transport and store ions and electrical charges at the nano level. Important electrode materials are nanoporous carbons, oxides, carbides, and sulfides. A particular focus is on 2D materials, especially MXene. Such materials make powerful electrodes for supercapacitors, lithium-ion or sodium-ion batteries for energy storage. The re- versible uptake and controlled release of ions also enable the desalination of seawater and ion separa- tion to separate pollutants such as lead or recover valuable materials such as lithium. We use various characterization methods, including in situ, for a comprehensive mechanistic understanding. In ad- dition, we are increasingly using digital methods for predictive materials research. Our collabora- tions include international basic research as well as industrial projects. CURRENT RESEARCH Digital energy materials. Digital methods allow us to better understand pro- cesses, and predictive tools support the development of novel nanomaterials. Digitalization is also a key tool for advancing battery production, as explored within the BMBF-funded ProZell DigiBatMat project with the Program Division Structure Formation and several other partners. We also use predictive tools to simulate ion transport within nanoporous carbon to create advanced supercapacitors (German-Polish 

10 GRENZFLÄCHENMATERIALIEN / INTERFACE MATERIALS FUNKTIONELLE MIKROSTRUKTUREN / FUNCTIONAL MICROSTRUCTURES PROF. DR. EDUARD ARZT, DR. XUAN ZHANG ZUSAMMENFASSUNG Mikrostrukturierte Oberflächen sind evolutionäre Strategien der Natur, die in unserer Gruppe als neue Materialkonzepte erforscht, entwickelt und bis zur Anwendungsreife gebracht werden. Der Fokus unserer Arbeiten lag dieses Jahr auf fibrillä- ren Haftsystemen für die temporäre, reversible Adhäsion und deren Anwendung in Robotik sowie der Medizin. Zuletzt wurde das Augenmerk verstärkt auf den Ablöseprozess von minia- turisierten Objekten gelegt, für den eine neue Metastruktur entwickelt wurde. Die Integration von Maschinellem Lernen in Verbindung mit optischer Kontaktbeobachtung eröffnet den Weg zu zuverlässiger Handhabung auch von schwierigen Ob- jekten. Im Bereich Biomedizin hat die Kooperation mit der Uni- versitätsklinik Homburg inzwischen zu ersten Heilversuchen an geschädigten Trommelfellen im Menschen geführt. CURRENT RESEARCH Progress in the Leibniz Competition project In the “MUSIGAND” project, funded by the Leibniz Association, progress was made towards improved control and reliability in bioinspired handling. Sever- al microstructure designs for reversible and switch- able micro-handling were proposed: slanted fibrillar micropattern with a sliding mechanism (Wang et al., Adv Mater Interfaces, 2022); geometrically modified fibrillar pattern by tuning the contact area (Barnef- ske et al., Adv Mater Interfaces, 2022); and a trigger plant-inspired metastructure with snap-through instability (Zhang et al., Adv Sci, 2022). Further, a cupped microstructure inspired by the octopus was developed for underwater attachment (Wang et al., Sci Adv, 2022; J R Soc Interface, 2022). In col- laboration with Prof. McMeeking, the INM-UCSB workshop “Designed materials and microstructures” was organized at the University of California, Santa Barbara, USA. Advanced handling of micro-objects Our bioinspired technology has been successfully demonstrated in the pick & place operations of var- ious objects. Due to their strong adhesion to other surfaces and lack of inertial forces, the handling of micro-objects requires novel release mechanisms. Common mechanical mechanisms lose their func- tion below a certain object mass, as the switching ra- tio of 2~3 is too low to release objects by gravitation or inertial effects. Inspired by the snap-through of the trigger plant in nature, a metastructure encod- ing the bistable curved beam was proposed with an extremely high switching ratio of ~104. Reversible miniaturized snap-through devices were success- fully realized by micron-scale direct printing and can be applied to universal scenarios, including dry and wet environments, or smooth and rough coun- ter surfaces (Zhang et al., Sci Adv, 2022). 

12 GRENZFLÄCHENMATERIALIEN / INTERFACE MATERIALS INTERAKTIVE OBERFLÄCHEN / INTERACTIVE SURFACES PROF. DR. ROLAND BENNEWITZ ZUSAMMENFASSUNG Der Programmbereich Interaktive Oberflächen hat die Neu- ausrichtung seiner Forschungsaktivitäten, insbesondere die Ausweitung der Studien zur taktilen Wahrnehmung von Mate- rialien, fortgesetzt. Die Strukturierung und Funktionalisierung von Oberflächen und die Entwicklung des Verständnisses phy- sikalisch-chemischer Mechanismen werden genutzt, um die mechanischen Eigenschaften von Materialien wie Reibung und Adhäsion zu bestimmen und zu nutzen. Die Interaktionen an Oberflächen werden für 2D Materialien wie Graphen oder MoS2, für Biomaterialien wie Hydrogele mit doppelten Netzwerken oder aber für mathematisch definierte Rauigkeiten auf Ober- flächen aus dem 3D-Drucker untersucht. Die Projekte basieren auf unserer Expertise in der experimentellen Nanomechanik. Zu den wichtigsten Ergebnissen des Jahres 2022 gehört die Kraftspektroskopie an einzelnen Polymeren eines Doppelnetz- werk-Hydrogels. Ferner wurden grundlegende Erkenntnisse zur taktilen Wahrnehmung von Gecomer-Oberflächen und zum Verhältnis zwischen der affektiven Bewertung von Geschenk- papieren und der Reibung der Fingerspitze auf den Papieren gewonnen. MISSION The Program Division Interactive Surfaces explores new materials with specific adhesion and friction properties and investigates the function of surface materials in haptics. We focus on molecular func- tionalization and structuring at the micrometer scale and investigate the physical chemistry of friction, wear, lubrication, deformation, and adhesion as well as the role of sliding friction in tactile perception. Materials of interest range from 2D materials over hydrogels to additively manufactured microstruc- tures and materials with switchable roughness. The projects draw on our expertise in experimental na- nomechanics and novel skin friction experiments. Single-molecule force spectroscopy is used in soft matter for biophysical applications. CURRENT RESEARCH Molecular stiffness cues of interpenetrating networks Double-network hydrogels allow tuning of their mechanical properties by combineing a host net- work with an interpenetrating guest network. In collaboration with the Program Division Dynamic Biomaterials, we established a method to study the mechanical properties of individual polymer chains in the networks using atomic force microscopy in a physiological buffer. For the first time, we have been able to address each network individually and thus quantify variations in molecular stiffness between different guest networks, even when the macro- scopic mechanical properties of the double network 



16 BIOGRENZFLÄCHEN / BIO INTERFACES BIOPROGRAMMIERBARE MATERIALIEN / BIOPROGRAMMABLE MATERIALS DR. SHRIKRISHNAN SANKARAN ZUSAMMENFASSUNG Die Juniorforschungsgruppe Bioprogrammierbare Materialien erforscht ein junges multidisziplinäres Feld, das die Gebiete der synthetischen Biologie und der Biomaterialien verbindet. Im Mittelpunkt steht die Entwicklung von Materialien mit ge- netisch programmierten Funktionalitäten für biosensorische Anwendungen. Sie sind in der Lage, auf Stimuli hin Wirkstoffe langfristig freizusetzen und das Zellverhalten zu beeinflussen. Mit Werkzeugen der synthetischen Biologie werden Proteine und Mikroben so programmiert, dass sie intelligente Funk- tionen erfüllen. Diese konstruierten biologischen Einheiten werden dann in entsprechend entwickelte polymere Matrizen eingebettet. Das Ergebnis sind funktionell vielseitige Verbund- materialien mit einer großen Bandbreite an Einstellbarkeit und In-situ-Kontrollmöglichkeiten. MISSION The Junior Research Group Bioprogrammable Mate- rials explores a young multidisciplinary field com- bining synthetic biology and biomaterials. It focusses on the development of materials with genetically programmed functionalities capable of biosensing, stimuli-responsive long-term drug release and ma- nipulation of cell behavior. Synthetic biology tools are used to program proteins and microbes to per- form smart functions. These engineered biological entities are then incorporated in appropriately de- veloped polymeric matrices, resulting in compos- ite materials with highly versatile functionalities, a wide range of tunability and in situ controllability. CURRENT WORK Within the Leibniz Science Campus, we made sig- nificant progress towards the development of Living Therapeutic Materials. Together with the program division Dynamic Biomaterials, we created hydro- gels in which engineered bacteria can be securely encapsulated. These constructs can sustain bacteria long-term and enable them to perform biosensing and drug release functions. One major highlight was the development of a Living Material that can produce and release therapeutically relevant doses of a pro-angiogenic protein initiated by light. This was able to stimulate angiogenic differentiation in vascular endothelial cells. In collaboration with Dr. Bin Qu at the UKS, we found that native immune re- sponses to such Living Therapeutic Materials can be minimized through careful selection of the bacterial strain and encapsulation material. Along with the program division Structure Formation, we combined gold nanorods with heat-responsive engineered bac- teria to create a system that can be controlled using near infrared light, which has high tissue penetration. This system is being combined with advances made along with the group of Prof. Rolf Mueller (HIPS) 

18 BIOGRENZFLÄCHEN / BIO INTERFACES DYNAMISCHE BIOMATERIALIEN / DYNAMIC BIOMATERIALS PROF. DR. ARÁNZAZU DEL CAMPO ZUSAMMENFASSUNG Der Programmbereich Dynamische Biomaterialien entwickelt instruktive synthetische Matrizen zur Einkapselung und als Schnittstelle zu lebenden Zellen. Wir zielen darauf ab, funk- tionelle in vitro Gewebemodelle und lebende Implantate für medizinische und technische Anwendungen zu entwickeln. Im Zentrum unserer Forschung stehen lichtempfindliche Moleküle und Hydrogele, die mit latenten Funktionen programmiert sind und bei Belichtung angeschaltet werden können, um Eigen- schaftsänderungen und Reaktionskaskaden zu regulieren. Wir sind auch an der Kompatibilisierung synthetischer Matrizen und lebender Organismen mit Verarbeitungstechnologien wie 3D-Druck oder Mikrofluidik für zellbasierte Diagnostika und the- rapeutische Technologien der nächsten Generation interessiert. Als längerfristige Perspektive beabsichtigen wir, Konzepte aus der Geweberekonstruktion auf die Synthese nachhaltiger und belastbarer technischer Materialien zu übertragen. MISSION The Program Division Dynamic Biomaterials devel- ops instructive synthetic matrices to encapsulate and interface with living cells. Our aim is to bioengineer functional tissues and living devices for medical and technical applications. At the core of our research are photoresponsive molecules and hydrogels pro- grammed with latent functions that can be unlocked upon light exposure to regulate property changes and response cascades in cells. We are also interest- ed in the compatibilization of living organisms with synthetic matrices and processing technologies like 3D printing or microfluidics towards next-genera- tion cell-based materials and devices. CURRENT RESEARCH Light-actuated interfaces triggering cellular responses The regulation of the properties of biomaterials us- ing light is a classical topic our research. We devel- oped mechanically active interfaces using synthetic, light-driven molecular motors and applied them to mechanically stimulate cellular responses. In coop- eration with the Program Division Interactive Sur- faces, the DWI-Leibniz Institute for Interactive Ma- terials and the University Strasbourg (SAW Project LightAct) we are integrating force sensors to quan- tify the forces applied by the motor and the cells in 2D and 3D scenarios. This tool is also used for the cooperation with biophysics partners at Saarland University (SFB 1027) and at GeorgiaTech (EU Pro- ject Mechanofibrosis). To be able to operate our ma- terials in vivo, we develop printable hydrogel optical waveguides that can guide light into the body (co- operation with Optical Materials). Using bioprinting technologies and multimaterial approaches, we fab- ricate hydrogel waveguides containing alternating

ANNETTE KRAEGELOH ZUSAMMENFASSUNG Der Programmbereich Nano Zell Interaktionen beschäftigt sich mit den Auswirkungen technisch hergestellter partikulärer Ma- terialien auf menschliche Zellen, um zu einer sicheren Anwen- dung hochentwickelter Materialien in technischen und biome- dizinischen Bereichen beizutragen. Ziel ist es zu verstehen, wie bestimmte Materialeigenschaften die Struktur und Biochemie der Zellen beeinflussen und wie die Materialeigenschaften mit Zellwechselwirkungen und Zellantworten verknüpft sind. Als Untersuchungsobjekte werden insbesondere anorganische Nanopartikel, aber auch 2D-Nanomaterialien eingesetzt und charakterisiert. Zur Lokalisation von Partikeln und Zellstruktu- ren werden vor allem lichtmikroskopische Techniken, wie die konfokale Laser-Raster-Mikroskopie, verwendet. Zur weiteren Analyse der Zellantwort werden darüber hinaus zellbiologische, biochemische und molekularbiologische Techniken angewandt. MISSION The Program Division Nano Cell Interactions ex- plores the effects of engineered particle-like ma- terials on human cells, to enable safe applications of advanced materials in technical and biomedical fields. It strives to understand how materials prop- erties influence structure and biochemistry of cells and how materials properties are linked to cell in- teractions and cell responses. Our purpose is to pave the way for the design of safer nanomaterials. In particular, we focus on using and characterizing inorganic nanoparticles and 2D nanomaterials. We use light microscopy techniques, such as confocal laser scanning microscopy to localize particles and analyze cellular structures. Further, we use cell-bi- ological, biochemical, and biomolecular techniques for the analysis of cellular responses. CURRENT RESEARCH Leibniz Research Alliance Advanced Materials Safety The group has obtained funding for the Leibniz Re- search Alliance (LRA) Advanced Materials Safety” (2022-2025). Prof. Andreas Fery (Leibniz Institute for Polymer Research Dresden, IPF) and Annette Krae- geloh are spokespersons of this initiative. The new alliance synergizes 12 Leibniz Institutes and further associated partners. Major goals of the alliance are: • developing design concepts for safer and sustain- able advanced materials, • determination and prediction of the impact of ad- vanced materials on human health and environ- mental organisms, • perception and knowledge transfer regarding ad- vanced materials and their sustainable application. 



24 NANOKOMPOSIT-TECHNOLOGIE / NANOCOMPOSITE TECHNOLOGY ELEKTROFLUIDE / ELECTROFLUIDS DR. LOLA GONZÁLEZ-GARCÍA ZUSAMMENFASSUNG Die Juniorgruppe Elektrofluide erforscht mit Förderung der ERC flüssige Alternativen zu den herkömmlichen festen Me- tall- und Halbmetallmaterialien der Elektronik. Sie entwickelt damit elektronische Komponenten und robotische Aktuatoren für vollständig weiche Maschinen. "Elektrofluide" sind Suspen- sionen fester, leitfähiger Partikel, die Elektronentransport er- möglichen, wie Flüssigkeiten strömen und oft nicht-Newton- sches Verhalten zeigen, das wir ausnutzen. Eine ausreichende Leitfähigkeit erreichen wir durch hohe Konzentrationen von Partikeln, die bei handhabbarer Viskosität transiente leitfähige Netzwerke bilden. Der Zusammenhang zwischen der Struktur und den rheoelektrischen Eigenschaften von Elektrofluiden steht im Mittelpunkt unserer Forschung. Die Gruppe untersucht die Wechselwirkungen von Partikel-Partikel-Reibung, Kontakt- widerstand, Perkolation, Volumenwiderstand und Suspensions- viskosität, um Ad-hoc-Elektrofluide für konkrete Anwendungs- fälle zu entwickeln. MISSION The Junior Group Electrofluids funded by the ERC investigates liquid alternatives to the traditional met- al and semiconductor solid materials used in elec- tronic components and robotic actuators to enable truly soft devices. “Electrofluids” are suspensions of solid conductive particles that allow the electron transport while flowing as liquids and often exhibit non-Newtonian behavior that we also exploit. We achieve sufficient conductivity using high concen- trations of particles that form transient conductive networks at manageable viscosity. The connection between the structure and the rheoelectrical prop- erties of electrofluids is at the heart of our research. The group investigates the interplay between parti- cle-particle friction, contact resistance, percolation, bulk resistance, and suspension viscosity to design ad hoc electrofluids for concrete applications. CURRENT RESEARCH Electrofluids with double percolation We have adapted the concept “double percolation” from the polymer blends to the Electrofluids. The strategy is to reduce the percolation threshold, i.e., the volume fraction of filler required to create a con- ductive network. For that, two immiscible solvents are mixed and a conductive filler with a strong af- finity for one of the phases is added. Carbon black (CB) as the conductive filler and polar/ nonpolar solvent pairs as matrices such as penty- leneglycol/PDMS 100 cSt were used. The unmodified CB surface is hydrophobic thus, it tends to interact better with nonpolar solvents. Under a light micro- scope, we observed a clear preference of CB particles

CARSTEN BECKER-WILLINGER ZUSAMMENFASSUNG Der Programmbereich Nanomere entwickelt multifunktionelle Schutzschichten, Kompaktwerkstoffe und Materialien für addi- tive Fertigungsverfahren auf Basis von Kompositen mit polyme- ren und hybriden Matrizes und mit nano- und mikroskaligen, funktionellen Additiven. Die funktionellen Additive können aus halbleitenden sowie keramischen oder metallischen Pati- keln bestehen. Neben kugelförmigen Partikeln kommen auch solche mit plättchenförmiger Morphologie zum Einsatz. Mit einer maßgeschneiderten Oberfläche versehen, erlauben die Partikel den Übertrag festkörperphysikalischer Eigenschaften anorganischer Materialien auf Polymere und Beschichtungen. Bei der Entwicklung neuer Werkstoffeigenschaften steht der Anwendungsbezug im Vordergrund. Schwerpunkt der Entwick- lungsaktivitäten liegen auf schwermetallfreien, aktiven Kor- rosionsschutzsystemen für Stahl und Aluminiumlegierungen, temperaturbeständigen, feuerfesten Bindemitteln für Naturfa- serkomposite und transparenten, selbstheilenden Beschich- tungen sowie Polymerkompositbasierten Materialien für die additive Fertigung. MISSION Activities of the Program Division Nanomers com- prise the development of functional coatings and bulk materials based on a polymer matrix composite concept. A distinct focus is set on application-orient- ed projects for industrial materials. Functions of in- terest are heavy metal free corrosion protection, fire resistant polymer matrix composites, temperature stable inorganic binders and transparent self-heal- ing surfaces. The materials are applied in electron- ics, medicine, optics, automotive, construction, en- gineering and additive manufacturing. CURRENT RESEARCH Fire resistant fibreboards from bush bio- mass / NaMiComp III The project phase NaMiComp III, supported by BMZ- GIZ and Saarland in cooperation with the University of Namibia (UNAM) was completed. The research re- sults on the fabrication of a fiberboard plate derived from bush biomass towards the Namibian economy were presented in front of the Namibian Biomass In- dustry Group (N-BiG) and various stakeholders in Namibia and also in Germany. The first application in focus of this framework is the use of the fire resistant fiberboards as construction materials for “low-cost- housing” in Namibia and other sub-Saharan African countries. For this reason a materials data sheet has been created and a marketing brochure was devel- oped together with GIZ Namibia to enable an im- proved advertising in front of the local industry in Namibia and industrial companies from Germany that intend to support the planning and construc- tion of a production line in the not too far future.

28 NANOKOMPOSIT-TECHNOLOGIE / NANOCOMPOSITE TECHNOLOGY OPTISCHE MATERIALIEN / OPTICAL MATERIALS DR. PETER W. DE OLIVEIRA ZUSAMMENFASSUNG Der Programmbereich Optische Materialien sieht seine Aufgabe darin, neue optische und elektrooptische Verbundwerkstoffe durch den Einbau von Nanopartikeln, die gezielte Erzeugung von Mikro- und Nano-Poren, Imprinting oder Prägung zu ent- wickeln. Diese Werkstoffe zeichnen sich durch eine spezifische Wechselwirkung mit Licht bzw. elektromagnetischer Strahlung aus. Kompetenz in der Modellierung von optischen Elementen, der nasschemischer Synthese organischer und organisch-anor- ganischer Matrices und der Herstellung chemisch modifizierter Nanopartikel, ermöglichen die Entwicklung neuer Werkstoffe mit angepassten physikalischen Eigenschaften. Die Gruppen- kompetenz liegt in der Grundlagenforschung und erstreckt sich bis zur anwendungsorientierten Forschung mit dem Ziel einer Verwertung in Zusammenarbeit mit Wissenschaft, KMUs (Klei- nen und Mittleren Unternehmen) und Industrie. Die in den vergangenen beiden Jahren entwickelte neue Akquisestrategie, erwies sich als äußerst erfolgreich, da viele Industriegetriebe- ne Projekte mit privater oder öffentlicher Förderung eingewor- ben werden konnten. Neben der gezielten Bindung langjähriger Partner umfasst die Akquisestrategie proaktive Schritte zur Ge- winnung neuer Kooperationspartner sowie angepasste Trans- fermechanismen. In der Berichtsperiode wurden u. a. Kompo- site aus Gasblasen und Polymeren, neuartige plasmonische Materialien oder optisch-hochtransparente Glasfaserverstärkte Polymere bearbeitet. MISSION The Program Division Optical Materials has the mis- sion to design new optical and electro-optical com- posite materials interacting with light. Structuring of inorganic, organic, or inorganic-organic hybrid materials takes place via the inclusion of nanopar- ticles, the generation of pores or nanobubbles or techniques like imprinting or embossing. Compe- tence in modeling of optoelectronic components, in wet chemical processes for the synthesis of hybrid hard or soft matrices and the production of nano- particles with chemical modifications enables the development of new materials with adapted physi- cal properties e.g. refractive index or conductivity. The competencies of the group range from basic to applied research aiming always at utilization. A spe- cial interest lies in the cooperation with customers from academia, SMEs and industry without being completely dependent on orders. The new adopted acquisition strategy, developed in the last two years, proofed to be very successful. In addition to the tar- geted retention of long-term partners, it included proactive steps to acquire new partners as well as a change in the transfer mechanisms. CURRENT RESEARCH These highlight topics were investigated in 2022: Coupling gratings for optical waveguides defined by silver colloids The goal of this work is to investigate diffractive grat- ings composed of colloidal silver particles as a way to couple light into and out of planar waveguides. Photochemical silver deposition was used on glass substrates coated with a thin photocatalytic TiO2 layer. Diffractive gratings consisting of Ag-colloids were created by UV-Laser interference and a nano- composite cladding was applied as a final step. The TiO2 layer acted as a planar waveguide, the gratings

TOBIAS KRAUS ZUSAMMENFASSUNG Der Programmbereich Strukturbildung erforscht die Bildung funktioneller Hybridmaterialien aus komplexen Flüssigkeiten. Wir untersuchen, wie sich dispergierte Metalle, Polymere, Keramiken und Biomoleküle hierarchisch zu Materialien ver- binden und wie die entstehenden Strukturen ihre Eigenschaf- ten bestimmen. Durch Streuung, Mikroskopie, systematische chemische Variation und in situ-Beobachtung erforschen wir grundlegende Wechselwirkungen zwischen Komponenten in Modellsystemen und ihre Auswirkungen während der Verarbei- tung. Die Eigenschaften der entstehenden Materialien prüfen wir mechanisch, elektrisch und optisch. Mit dem so gewonne- nen Verständnis entwickeln wir Prozesse, um Materialien für Elektronik, Optik und Sensorik auf Längenskalen zwischen Na- nometern und Millimetern nahe Raumtemperatur und an Luft gezielt zu strukturieren. Nachhaltiges Wirtschaften erfordert, dass Materialien am Ende ihrer Lebensdauer wieder in nutzba- re Bausteine zerlegt werden können. Daher untersuchen wir, wie sich heterogene Materialien und Materialverbunde wäh- rend ihrer Lebensdauer verändern. Wir modifizieren Material- struktur und Grenzflächen, um Lebensdauern zu erhöhen, Wie- derverwendung zu ermöglichen und Recycling zu erleichtern. MISSION The Program Division Structure Formation investi- gates the formation of hybrid materials from com- plex liquids. We study how dispersed precursors join hierarchically to form materials and how emerging structures affect their properties. Scattering, micros- copy, systematic chemical variation and in situ ob- servation allow us to investigate fundamental inter- actions between components in model systems and their effects during processing. We test the proper- ties of the resulting materials and use our insights to structure materials for electronics, optics, and sensing on length scales between nanometers and millimeters near room temperature and in air. We support the transition to a more sustainable econo- my and investigate how complex hybrid materials change during their lifetimes and how we can de- sign them for reuse and recycling. CURRENT RESEARCH Conductive networks for soft electronics The group investigates new electrically conductive materials for future electronics that are integrated in everyday objects, stretchable, and soft. They contain networks of nano- and microscale conductive com- ponents in insulating matrices or on surfaces. We cooperate with the Electrofluids Group that rheolog- ically analyzes network structure conductivity; with Prof. Tanja Schilling (Freiburg University) to model the hierarchical structure of conductive networks, and with companies like Continental (BMBF-funded project SensIC) for the application of the materials. We address soft robotics in collaboration with en- gineers from TU Dresden (Dr. Markus Henke) and conductive networks in battery materials in collab- oration with Energy Materials in the BMBF project DigiBatMat. 

32 QUERSCHNITTSBEREICH / CROSS LINKING UNIT INNOVATIONSZENTRUM INM / INNOVATIONCENTER INM DR. CARSTEN BECKER-WILLINGER, DR. PETER W. DE OLIVEIRA ZUSAMMENFASSUNG Das InnovationsZentrum INM bildet die Schnittstelle zwischen den INM-Programmbereichen und der Industrie. Insbesonde- re betreibt es Technologie-Scouting innerhalb des INM, um in der breitgefächerten Forschung der Programmbereiche gezielt anwendungsreife Ergebnisse zu identifizieren. Gemeinsam mit den Programmbereichen werden Strategien erarbeitet, wie der Technologiereifegrad dieser Entwicklungen auf ein Niveau geho- ben werden kann, das es erlaubt, geeignete Industriepartner für Kooperationsprojekte zu gewinnen. In diesem Zusammenhang unterstützt das InnovationsZentrum INM beim Aufbau von Ma- terialplattformen, der Realisierung von Demonstratoren und bei der Auffindung von Industriepartnern für öffentlich geförderte Projekte mit Industriebeteiligung zur Erhöhung des Technolo- giereifegrades. Dies dient letztlich der Initiierung, Koordination und Implementierung von direkten Industriekooperationen. In Industriekooperationen übernimmt das InnovationsZentrum INM die Aufgabe, die Umsetzung von Materialentwicklungen in den Pilotmaßstab, Materialbegleitende Validierung und Optimierung von Produktionsprozessen und ggf. modulare Automatisierung vorzubereiten. All dies ermöglicht eine umfassende und ef- fiziente Umsetzung neuer Ideen vor dem Hintergrund starken Wettbewerbs und zunehmend verkürzter Produktzyklen bei High-Tech-Produkten. Im Berichtszeitraum lag der Schwerpunkt auf dem Transfer ökologisch und ökonomisch nachhaltiger Tech- nologien in Richtung auf zukünftige Anwendungen. MISSION The Innovation Center INM is an interface between the program areas of INM and the industry. It con- ducts technology scouting within the INM to identify results from research in the program divisions that are ready for application, and develops strategies to raise the degree of technological maturity to a level that allows industrial cooperations. In direct cooper- ation with the industry, the InnovationCenter INM develops materials from the laboratory to pilot scale through scale up, material-related validation and op- timization of production processes and, if necessary, modular automation. This enables a comprehensive and efficient implementation of new ideas against the background of strong competition and increas- ingly short product cycles for high-tech products. CURRENT RESEARCH & DEVELOPMENT The InnovationCenter INM currently develops natu- ral fiber-based composites for a use as construction boards in building and furniture industry. During previous GIZ-funded cooperation project NaMiComp with the University of Namibia, a new type of inor- ganic binder with a carbon footprint improved by a factor 4 compared to concrete was developed in the program division Nanomers. Based on this new ma- terials platform sustainable, fire resistant acia fiber- boards could be obtained, that fulfill the requirements for the building industry. In the InnovationCenter INM larger lab size demonstrators were fabricated and the effort is widened up to produce also reed- based construction boards in the framework of fu- ture industry projects.

38 HIGHLIGHTS ELECTROCHEMICAL LITHIUM RECOVERY FROM AQUEOUS SOLUTIONS LEI WANG, STEFANIE ARNOLD, PANYU REN, VOLKER PRESSER ENERGY MATERIALS One of the most critical elements for the continued eletricification, electromobility, and large-scale implementation of renewable energy sources is lithium. With the widespread use of lithium-ion batteries in electric vehicles and portable electronic devices, the demand for lith- ium has increased dramatically. So far, most lithium extraction meth- ods have focused on brine and ore deposits, while the vast amount of lithium in the earth's oceans and other aqueous media remains un- tapped due to the significant challenges involved. Our research team has been working to overcome these challenges and develop an efficient and cost-effective system for lithium recovery from seawater. We have developed a system that combines Li-selective ceramic membranes and a simple redox flow electrolyte. This inno- vative approach enables continuous lithium recovery from seawater and overcomes the limitations of electrodialysis-based systems. The lithium-extraction redox flow battery (LE-RFB) can extract dissolved lithium with a purity of 93.5% from simulated seawater, correspond- ing to a high Li/Mg selectivity factor of about 500.000:1. Furthermore, benefiting from a low operating voltage, only 2.5 Wh of energy con- sumption is required to extract 1 g of lithium. Our research has the potential to revolutionize the lithium extrac- tion industry by providing a cost-effective and scalable solution for recovering lithium from seawater. By tapping into this vast resource, we can help meet the growing demand for lithium while minimizing the environmental impact of lithium mining and extraction. We ex- pect that our findings will contribute to the development of a more sustainable and efficient energy system, benefiting both industry and society as a whole. L. Wang, S. Arnold, P. Ren, Q.

40 HIGHLIGHTS THE PAST, THE PRESENT AND THE FUTURE OF SCIENCE – PROFESSOR EDUARD ARZT IN INTERVIEW Eduard Arzt has, as Scientific Director, been at the helm of INM for one and a half decades and has steered its fortunes in an increasingly complex and competitive scientific world. After his transition- ing to the University of California in San Diego, we have asked him to tell us about his experiences: his challenges in running INM, how he chooses his research topics and how he sees science develop- ing in the future. the fact that virtually all members of the institute were very open to the changes – in contrast to political stakeholders, whose resistance was not helpful. The subsequent success of the INM is the success of all of us. YOUR CAREER SPANS FOUR DECADES OF SCIENTIFIC DEVELOPMENT. TO WHAT EXTENT HAS THE WAY SCIENCE IS DONE CHANGED DURING THIS TIME? There is no doubt that science has evolved into a complex machinery over this time, which places totally new demands on scientists. Not only has the speed of development increased, but so has the complexity of research questions and the need to “sell excellence” in order to procure further fund- ing. In addition, I deplore the increasing tyranny of metrics, which is fed by the misunderstanding that quality can be controlled by numerical indica- tors. I firmly believe that true science will continue to hinge on unusual, creative ideas, on deepening the understanding, and on what could be called scientific humility – as there is so much more we do not know. It will certainly be exciting to see to what extent artificial intelligence will influence this development. YOU HAVE WORKED IN MANY DIFFERENT FIELDS OF MATERIALS SCIENCE OVER THE COURSE OF YOUR SCIENCE CAREER. AS A SCIENTIST, HOW DO YOU ACTUALLY COME UP WITH NEW IDEAS? Materials science is a wonderful playground for ideas, as it touches on so many areas of life. That is why I tried to tackle a completely new subject YOU ASSUMED LEADERSHIP OF INM IN A DIFFICULT PHASE AND INITIATED A RE- ORIENTATION IN TERMS OF CONTENT AND ATMOSPHERE. WHAT WERE THE BIGGEST CHALLENGES? Up to 2007, INM had gone through the first “life cy- cle” of an institute; in the process, it had become so immersed in transfer research that it had lost con- tact with the scientific community. I consider my- self very fortunate that in the years that followed we succeeded in revitalizing the institute by bring- ing in new interesting people and future-oriented scientific topics; we also developed a new style of appreciative personal interaction without which creativity cannot flourish. I benefited greatly from 

42 HIGHLIGHTS INM FELLOW INVESTIGATES THE PHYSICS OF LIVING CELLS HEIKO RIEGER Heiko Rieger from Saarland University is the seventh Fellow of the INM. As a professor of Theoretical Physics he complements the insti- tute’s biologically oriented work with theoretical aspects. Rieger has been Professor of Theoretical Physics at Saarland Univer- sity since 1999. After completing his doctorate in theoretical physics at the University of Cologne in 1989, he spent postdoctoral stays at the University of Maryland and the University of California in Santa Cruz (both USA). In 1995 he habilitated at the University of Cologne and worked on a Heisenberg scholarship at the Jülich Research Center before moving to Saarbrücken. Visiting professorships have taken him to Tokyo Metropolitan University, École Normale Supérieure in Paris and Université Paris Sud. In 2016 he was awarded an honorary doctorate by the University of Szeged, Hungary. Rieger has been co- operating with the INM for a long time, for example in the Univer- sity’s Collaborative Research Center SFB 1027 Physical Modeling of Non-Equilibrium Processes in Biological Systems, for which he has been spokesman since 2013. Statistical physics, theoretical biophysics and computer-aided simula- tions are Heiko Rieger’s specialty. One of his focal points is process- es in biological systems, such as the behavior of immune cells or the growth of tumor cells. Together with the Program Division Dynamic Biomaterials, Rieger investigates the processes at the so-called immu- nological synapse, the point at which immune cells come into contact with other cells, such as cancer cells. Another collaboration focuses on amoeboid cell migration, the movement of cells through complex environments like the extracellular matrix, and how it can be manip- ulated with light induced (optomechanical) forces. For the physicist, the application aspect is what makes this interdisciplinary coopera- tion so appealing: “Of course, first and foremost I want to understand how things work. But it's even nicer when something new can emerge from this understanding,” Rieger emphasizes. And this is exactly what the researchers want to achieve together: The development of novel biomaterials, especially for use in therapy and medicine. 

44 HIGHLIGHTS FOCUS ON NEW PEOPLE: OSKAR STAUFER Oskar Staufer studied at Heidelberg University and obtained a PhD in Biology at the Max Planck Insti- tute for Medical Research in 2020. Then he moved to the University of Oxford as a Marie Skłodowska Curie Fellow to perform postdoctoral work in immunotherapy. Since 2022 he is an independent researcher within the Pharmaceutical Research Alliance Saarland (PRAS). CAN YOU TELL US AN IDEA OF WHAT IMMUNO-MATERIALS ARE? Immuno-materials are designed to interact with the immune system in a controlled manner. This interaction can be aimed at eliciting an immune response, such as stimulation of the immune sys- tem, or at avoiding an immune response to reduce the likelihood of rejection of implants. The term encompasses a broad range of materials including polymers, metals and biological materials. WHAT FASCINATES YOU ABOUT THIS RESEARCH AREA? Immuno-materials are fascinating because of their ability to interact with the body’s natural defense system in a controlled way. They offer the potential to develop more effective therapies for a variety of medical conditions. The combination of material science and immunology creates a new and excit- ing field of study with the potential to significant- ly impact human health. This is truly fascinating! WHAT WOULD YOU LIKE TO ACHIEVE IN FIVE YEARS? I am eager to unleash the full potential of immu- no-materials and their role in regulating immunity for both therapy and research. My goal is to cre- ate a toolbox of materials mimicking the nature of the immune system, allowing us to treat diseases and to gain a deeper understanding of conditions like cancer. At the core of my passion is a desire to understand the interplay between biochemical and biophysical factors in regulating immunity. I recognize that this is a highly ambitious goal for a five-year plan. However, with the supportive en- vironment at the INM, I am certain that we will make significant strides and exciting discoveries.
