Terahertz Spectroscopy
In article number 2306200, Tao Zhao, Tianwu Wang, Guangyou Fang, and co‐workers generated broadband terahertz pulses by dual‐color laser‐induced air plasma. Subsequently, the interaction between terahertz waves and MXene reveals the localized charge carrier effects caused by electron‐phonon scattering. In the image, ‘e’ and ‘p’ represent electrons and phonons, respectively,...
The transport properties of charge carriers in MXene, a promising material, have been studied using terahertz time‐domain spectroscopy (THz‐TDS) to examine its potential applications in optical and electronic devices. However, previous studies have been limited by narrow frequency ranges, which have hindered the understanding of the intrinsic mechanisms of carrier transport in MXenes. To address this...
The construction of efficient, durable, and non‐noble metal electrocatalysts for oxygen evolution reaction (OER) is of great value but challenging. Herein, a facile method is developed to synthesize a series of trimetallic (W/Co/Fe) metal–organic frameworks (MOFs)‐derived carbon nanoflakes (CNF) with various Fe content, and an Fe‐dependent volcano‐type plot can be drawn out for WCoFex‐CNF. The optimized...
Rechargeable Zn‐ion batteries are promising candidates for wearable energy storage devices. However, their performance is severely restricted by the low conductivity and inferior mass loading. Herein, a new type of the textile based electrodes with 3D hierarchical branched design is reported. Both Ni nanoparticles and carbon nanotubes are used to build conductive coatings on the textiles. The 3D hierarchical...
