Bottom‐Up Programming of Cell States in Cancer Organoids with Defined Synthetic Adhesion Cues

open access: yesAdvanced Materials, EarlyView.
A bottom‐up biomaterial platform is developed to program transcriptomic states in pancreatic cancer organoids by tuning adhesion cues within synthetic matrices. By combining a Design of Experiments framework with multiobjective optimization, matrix compositions are identified that enrich specific cellular programs like EMT.

Hydrogelation via Supramolecular Copolymerization of Structural Water within Adaptive Metal–Organic Fibers

open access: yesAdvanced Materials, EarlyView.
Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.

Das „Social Web" als Demokratieverstärker?

open access: yes, 2012
Am 14. Juni 2012 unterbricht David Tynnauer, ein Absolvent der Philosophie, zusammen mit einem Kamerateam, eine Vorlesung des Univ. Prof. Konrad Liessmann im Hörsaal 33 der Universität Wien. Er verlangt fünf Minuten Zeit, um vom Podium herab die Machtlosigkeit der Philosophie angesichts des Unrechts in der Welt und die Selbstgerechtigkeit ihrer ...

Positively Charged Polymer‐Brush MOFs for Large‐Area, Pressure‐Resistant Gas Separation Membranes

open access: yesAdvanced Materials, EarlyView.
A universal POPA strategy enables positively charged polymer‐brush MOFs with self‐adaptive interfacial interlocking to resist aggregation under fast processing. This design ensures seamless dispersion within large‐area selective layers, achieving 1 m‐wide roll‐to‐roll fabrication of pressure‐resistant MMCMs with tunable CO2 separation performance ...

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Politische Konsumentinnen im Social Web: Politische Konsumentinnen im Social Web

open access: yes, 2017
Politische Beteiligung wandelt sich. Der sozialwissenschaftliche Diskurs weist immer wieder auf eine Hinwendung der Bürger_innen zu neuen Formen des Engagements hin, die außerhalb der Einflusskanäle des repräsentativen Systems liegen. Dem Social Web kommt in diesem Prozess eine besondere Bedeutung zu, da es potenziell einen Raum für bürgerschaftliche ...

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

open access: yesAdvanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...
