Lasing from cells has recently been subject of thorough investigation because of the potential for sensitive and fast biosensing. Yet, lasing from individual cells has been studied in high‐quality resonators, resulting in limited dependence of the lasing properties on the cellular microenvironment. Here, lasing is triggered by cells floating in a l...
Ultrathin nanostructured membranes are widely pursued to apply into different processes ranging from air separation to seawater desalination. Here, freestanding carbon nanomembranes (CNMs) are employed to dehydrate vaporous alcohols at room temperature. The structure of the microporous material is addressed by measuring permeation rates of homologo...
Mixed ionic–electronic conductors (MIECs) that display high oxide ion conductivity (σo) and electronic conductivity (σe) constitute an important family of electrocatalysts for a variety of applications including fuel cells and oxygen separation membranes. Often MIECs exhibit sufficient σe but inadequate σo. It has been a long‐standing challenge to ...
Artificial spin ice (ASI) systems have emerged as promising hosts for magnonic applications due to a correspondence between their magnetic configuration and spin dynamics. Though it has been demonstrated that spin-wave spectra are influenced by the ASI microstate the precise nature of this relationship has remained unclear. Recent advances in contr...
Spinal cord injury (SCI) is one of the most debilitating injuries and transplantation of stem cells in a scaffold is a promising strategy for the treatment. However, the stem cell treatment of SCI has been severely impaired by the increased generation of reactive oxygen species in the lesion microenvironment, which can lead to a high level of stem ...
Actuated by the needs of high power electronic devices heat dissipation, diamond/Cu composites with excellent thermal dissipation properties have been considered as the next generation of thermal management material. Herein, an easy-to-operate intermittently electroplated method is developed for coating micro-sized particles and successfully applie...

Crystallization of ammonium polyvanadate is a key procedure for the production of vanadium pentoxide. The kinetics of nucleation of ammonium polyvanadate and the effects of impurities on the nucleation including sodium ion, potassium ion, hexavalent chromium ion, dihydrogen phosphate were studied in this research by using conductivity method. The s...

Understanding the effects of lattice strain on oxygen surface and diffusion kinetics in oxides is a controversial subject that is critical for developing efficient energy storage and conversion materials. In this work, high-quality epitaxial thin films of the model perovskite La0.5Sr0.5Mn0.5Co0.5O3-δ (LSMC), under compressive or tensile strain, wer...
