Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials
Advanced Science, EarlyView.ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Advanced Science, EarlyView.An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge

Recycling of inorganic waste in monolithic and cellular glass-based materials for structural and functional applications [PDF]
, 2016 The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be

Advanced Science, EarlyView.This study develops neural bioprinted piezoelectric scaffolds which construct local “sensor‐effector” circuit, inspired by the skeletal interoception system. Upon US stimulation sensing and mechanoelectrical coupling by PLLA nanofibers, the incorporated DRG neurons effect through Ca2+ influx‐induced enhanced secretion and expression of CGRP.

Advanced Energy Materials, EarlyView.A synergistic dual‐modulation strategy is employed in Yb‐filled skutterudites through concurrent indium filling and tellurium doping to optimize electronic band structure and phonon scattering. Cooperative band convergence and nanoprecipitate‐induced lattice distortions yield a high zT of 1.72 and enable an ultra‐efficient thermoelectric device with 8 ...
