Regiorandom Polythiophenes for Fully Stretchable Electrochemical Transistors and Logic Circuits

Advanced Functional Materials, EarlyView.
Regiorandom (RRa) polythiophenes, once regarded as unsuitable for electronics, exhibit exceptional switching performance via volumetric electrochemical doping. Optimized RRa‐based organic electrochemical transistors (OECTs) achieve a high on/off ratio (≈104), stable operation under 200% strain, and enable fully stretchable logic gates, demonstrating ...

Development of a nano-Al/CuO based energetic material on silicon substrate [PDF]

, 2007
Nanoenergetic materials nEMs have improved performances compared to their bulk counterpart or microcounterpart. The authors propose an approach to synthesize an Al/CuO based nEM that has several advantages over previous investigations such as enhanced ...

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

Advanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Rich polymorphism of a rod-like liquid crystal (8CB) confined in two types of unidirectional nanopores [PDF]

, 2008
We present a neutron and X-rays scattering study of the phase transitions of 4-n-octyl-4'-cyanobiphenyl (8CB) confined in unidirectional nanopores of porous alumina and porous silicon (PSi) membranes with an average diameter of 30 nm. Spatial confinement

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

Cryoprotective effect of trehalose and maltose on washed and frozen stored beef meat

Czech Journal of Food Sciences, 2011
The cryoprotective effects of trehalose and maltose (w = 2-10%) on washed beef meat were investigated. Washed beef meat produced from fresh beef meat was frozen and stored for 360 days at -30°C.
