Ti–Bi Nanosheets
In article number 2302253, Jing Xu, Xucai Yin, and co‐workers report novel titanium‐doped bismuth nanosheets (Ti–Bi NSs) for electrochemical carbon dioxide reduction. The prepared Ti–Bi NSs catalyst possesses the open and ordered ultrathin nanosheet structure, which could provide a large number of exposed active sites and a fast mass transport channel. Moreover, Ti doping is beneficial...
The electrochemical carbon dioxide reduction reaction (E‐CO2RR) to formate is a promising strategy for mitigating greenhouse gas emissions and addressing the global energy crisis. Developing low‐cost and environmentally friendly electrocatalysts with high selectivity and industrial current densities for formate production is an ideal but challenging goal in the field of electrocatalysis. Herein, novel...
Metallic MoS2 (i.e., 1T‐MoS2) is considered as the most promising precious‐metal‐free electrocatalyst with outstanding hydrogen evolution reaction (HER) performance in acidic media comparable to Pt. However, sluggish kinematics of HER in alkaline media and its inability for the oxygen evolution reaction (OER), hamper its development as bifunctional catalysts. The instability of 1T‐MoS2 further impedes...
Fish‐Wearable Data Snooping Platform
In article number 2107232, Xiangyu Chen and co‐workers report a fish‐wearable data snooping platform (FDSP) based on an air sac triboelectric nanogenerator, which is integrated with multiple functions of disinfection, mechanical energy harvesting, real‐time monitoring and wireless data transmission. The FDSP offers an alternative for studying fish kinematics and...
Conventional approaches to studying fish kinematics pose a great challenge for the real‐time monitoring of fish motion kinematics. Here, a multifunctional fish‐wearable data snooping platform (FDSP) for studying fish kinematics is demonstrated based on an air sac triboelectric nanogenerator (AS‐TENG) with antibacterial coating. The AS‐TENG not only can harvest energy from fish swimming but also serves...
Metal–organic frameworks (MOFs), built from organic linkers and metal ions/clusters, have emerged as highly promising materials for wide applications. Combining highly porous crystalline MOFs with the surface‐enhanced Raman scattering (SERS) technique can achieve unprecedented advantages of high selectivity, high sensitivity, and expedience in analysis and detection. In this critical review, the aim...
Researchers have devoted a lot of efforts on pursuing light weight and high flexibility for the wearable electronics, which also requires the related energy harvesting devices to have ultrathin thickness and high stretchability. Hence, an elastic triboelectric nanogenerator (TENG) is proposed that can serve as the second skin on human body. The total thickness of this TENG is about 102 µm and the...
