AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

An external potential dynamic study on the formation of interface in polydisperse polymer blends

, 2009
The formation of interface from an initial sharp interface in polydisperse A/B blends is studied using the external potential dynamic method. The present model is a nonlocal coupling model as we take into account the correlation between segments in a ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Fragmentation of Chitosan by Acids

The Scientific World Journal, 2013
Fragmentation of chitosan in aqueous solution by hydrochloric acid was investigated. The kinetics of fragmentation, the number of chain scissions, and polydispersity of the fragments were followed by viscometry and size exclusion chromatography.

Beugungsmikroskopie polydisperser Systeme

Zeitschrift für Naturforschung A, 1957
In Teil I1 wurde die HOSEMANNsche Interferenztheorie polydisperser Partikelhaufwerke erweitert und auf den zweidimensionalen Fall von Kreisscheibchen umgerechnet. Die theoretischen Ergebnisse werden durch Beugungsbilder von Modellstrukturen veranschaulicht und geprüft.
