Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

C02-Minderungsmöglichkeiten im Kraftwerkssektor

open access: yes, 1991
Unter Klimatologen besteht weitgehende Übereinstimmung, daß die durch menschliche Tätigkeit freigesetzten Spurengase das Klima verändern. Unter diesen Spurengasen nimmt Kohlendioxid eine herausragende Rolle ein. Es gilt also, den CO2-Ausstoß zu verringern.

Compression‐Tension‐Asymmetry and Stiffness Nonlinearity of Collagen‐Matrigel Composite Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
Self‐assembled collagen hydrogel matrices are widely used in tissue engineering applications. These matrices stiffen and contract laterally under tension due to fiber alignment and soften and collapse under compression due to fiber buckling. It is demonstrated that filler materials, such as Matrigel, linearize the mechanical behavior of collagen ...
