Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Creative Destruction versus Robert Frank's Progressive Consumption Tax

open access: yesQuarterly Journal of Austrian Economics
Joseph Schumpeter, like Ludwig von Mises, thought of capitalism as a process that often, over time, turned luxuries into necessities. Schumpeter warned that assessments that ignored this process, which he termed creative destruction, would misconstrue ...

Zähmung eines blauen Gases—Struktur und Chemie von Hexafluorthioaceton

open access: yesAngewandte Chemie, EarlyView.
Hexaflouorthioaceton (1), ein blaues Gas bei Raumtemperatur, wurde durch Vakuumpyrolyse des zyklischen Dimers bei 660 °C synthetisiert. Wir diskutieren grundlegende Eigeschaften des schwer greifbaren 1, einschließlich Einkristallstruktur und Kernmagnetische Resonansspektroskopie, obwohl es eine starke Tendenz zur Dimerisierung selbst bei –74 °C zeigt ...

Mehrfarbige und lichtintensitätsabgeschwächte Reaktionen von Proteinhydrogelen durch Photoregulierte Vernetzungsdynamik

open access: yesAngewandte Chemie, EarlyView.
In ein vollständig auf Proteinen basierendes Hydrogel wurden zwei orthogonale Photorezeptoren integriert, um die reversible Manipulation der Steifigkeit durch rotes/fernrotes Licht und den irreversiblen Gel‐Sol‐Übergang durch grünes Licht zu ermöglichen.

Passivierung von Defektzuständen in organischen n‐Typ‐Ladungstransferkomplexen durch molekularen Sauerstoff

open access: yesAngewandte Chemie, EarlyView.
O2 verbessert den Ladungstransfer in organischen n‐Typ‐Donor‐Akzeptor‐Ladungstransferkomplexen (CTCs) durch physisorptive Passivierung von Ladungsträgerfallen. Durch die Unterdrückung der Rekombination und die Förderung langlebiger delokalisierter Ladungsträger verbessert O2 den Elektronentransport und die Leitfähigkeit ohne Dotierung.

Taming a Blue Gas—Structure and Chemistry of Hexafluorothioacetone

open access: yesAngewandte Chemie International Edition, EarlyView.
Hexafluorothioacetone (1), a blue gas at r.t., was synthesized by flash vacuum pyrolysis of its cyclic dimer at 660°C. We discuss fundamental properties of elusive 1, including single‐crystal structure and nuclear magnetic resonance spectroscopy, despite its tendency to dimerize even at –74°C.

Multicolor and Attenuated Light Intensity Responses in Protein Hydrogels Arising from Photoregulated Crosslink Dynamics

open access: yesAngewandte Chemie International Edition, EarlyView.
A fully protein‐based hydrogel integrated two orthogonal photoreceptors to enable reversible manipulation of stiffness with red/far‐red light and irreversible gel‐sol transitions with green light. Unexpectedly, high‐intensity red light results in attenuated stiffening and dark‐adaptation, arising from increased crosslinking dynamics in the ...

Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

open access: yesAngewandte Chemie International Edition, EarlyView.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.
