Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics

Advanced Materials Technologies, EarlyView.
Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and

Block copolymers of poly(L-lactide) and poly(ε-caprolactone) or poly(ethylene glycol) prepared by reactive extrusion [PDF]

, 1996
Blends of poly(L-lactide) (PLLA) and poly(-caprolactone) (PCL) were prepared in a co-rotating twin screw miniextruder (40 rpm, 200°). It was attempted to prepare multiblock copolymers by allowing a controlled number of transesterification reactions ...

Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Vanadium oxide monolayer catalysts. I. Preparation, characterization, and thermal stability [PDF]

, 1979
Vanadium oxide catalysts of the monolayer type have been prepared by means of chemisorption of vanadate(V)-anions from aqueous solutions and by chemisorption of gaseous V2O3(OH)4.

The polymer phase of the TDAE-C$_{60}$ organic ferromagnet [PDF]

, 2002
The high-pressure Electron Spin Resonance (ESR) measurements were preformed on TDAE-C$_{60}$ single crystals and stability of the polymeric phase was established in the $P - T$ parameter space.

Simple Growth Models of Rigid Multifilament Biopolymers

, 2004
The growth dynamics of rigid biopolymers, consisting of $N$ parallel protofilaments, is investigated theoretically using simple approximate models. In our approach, the structure of a polymer's growing end and lateral interactions between protofilaments ...

Hyperviscous Diabetic Bone Marrow Niche Impairs BMSCs Osteogenesis via TRPV2‐Mediated Cytoskeletal‐Nuclear Mechanotransduction

Advanced Science, EarlyView.
Diabetic bone marrow exhibits pathological ECM hyperviscosity that activates TRPV2‐mediated Ca2⁺ influx, leading to perinuclear F‐actin disassembly, nuclear deformation, and chromatin condensation. This cytoskeletal‐nuclear decoupling suppresses osteogenic differentiation of BMSCs.
