ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

研究了平板-平板电极、多针-平板电极和筛网电极3种电极结构DBD的放电特性,通过测量电压-电流波形图及放电发光图比较了它们的区别,并从放电机理角度对实验结果作了解释。结果表明:平板-平板电极DBD表现为稳定的细丝状放电。而多针-平板电极DBD融合针尖的电晕效应,使得放电空间中呈现扩散圆锥形放电。筛网电极DBD可以实现大气压辉光放电(APGD),放电更加均匀,放电空间内看不到放电细丝的存在。

ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...
