A porous liquid crystalline elastomer actuator filled with an ionic (PLCE-IL) is shown to exhibit the functions of two classes materials: electrically responsive, deformable materials for sensing and soft active stimuli-triggered actuation. On one hand, upon order-disorder phase transition aligned mesogens, PLCE-IL behaves like a typical capable reversible shape change can be used assemble light-fuelled robot. other at temperatures below transition, that sustain sense large deformations...

<title>Abstract</title> High value-added azobenzene liquid crystal elastomers (AZO-LCEs) derived from styrene-butadiene-styrene triblock copolymer (SBS) are herein developed. The glassy polystyrene (PS) domains in SBS that spontaneously separate LCEs can provide the self-supporting template during actuation and lock LC orientation, enabling reprogrammable, reshapable recyclable AZO-LCE actuators. decoupling effect between oriented continuous polybutadiene (PB) phase leads to arrangement of...

Sarcopenia, the accelerated loss of muscle mass and function, is commonly associated with aging, especially in older adults. While low serum calcium has been linked to individuals over 50, its relationship sarcopenia younger adults (20-60 years) unclear. This study examines this association using data from National Health Nutrition Examination Survey (NHANES) 2011 2018. population-based, cross-sectional analyzed participants aged 20-60 NHANES 2011-2018. Individuals missing were excluded....

A porous liquid-crystalline network (LCN), prepared by using a template method, was found to exhibit peculiar actuation functions. The creation of porosity makes the initially hydrophobic LCN behave like hydrogel, capable absorbing large volume water (up ten times sample size LCN). When amount absorbed is relatively small (about 100 % swelling ratio), displays anisotropic in and, same time, retained uniaxial alignment mesogens ensures thermally induced shape change associated with...

Abstract A porous actuator is prepared using a liquid crystal elastomer (LCE) loaded with metal‐organic framework (MOF) nanoparticles (MIL‐88A). While the swellable MOF additive endows LCE nanoscale pores, after its removal by chemical etching, macroporous obtained. This LCE‐MOF displays several interesting features. 1) Selective etching allows in water to curl one direction and then reverse curling owing differential absorption of nano‐ layers. 2) The stretching‐induced alignment mesogens...

In order to promote the technological applications of perovskite manganites, a great fundamental interest has been devoted tailoring and/or enhancing their magnetotransport properties. Design and fabrication manganite-based nanocomposites offer potential tailor this work, we illustrate promising concept 0-3 type manganite/insulator composites (where manganite nanoparticles are uniformly discretely embedded in three-dimensional-connectivity insulator matrix) through example La0.67Ca0.33MnO3...
