Summary: In this study, Co doped Ni(OH)2 and NiOOH array structure were synthesized using a hydrothermal method. The use of vertical hanging Ni foam provided sufficient reaction sites to ensure the full growth of the array structure, resulting in a large mass loading of active materials. The presence of embedded CH3COO- and strong electron exchange between Ni(OH)2 or NiOOH and Ni facilitated efficient ion and electron transport, leading to improved capacitive and rate performance of the material.

Summary: Researchers have developed a simple, general, and efficient method to stimulate circularly polarized light (CPL) activity in achiral perovskites. By forming van der Waals heterojunctions between chiral and achiral perovskites, spin-polarized electrons from chiral perovskites are received by achiral perovskites, resulting in nonequilibrium spin distribution and CPL activity. The polarization degree of CPL in achiral perovskites is at least one order of magnitude higher than in chiral perovskites and can be flexibly designed by tuning chemical compositions, operating temperature, or excitation wavelengths.

Summary: The enhanced catalytic activity of silver nanowire (AgNW) and palladium nanoparticles (PdNPs) heterostructure in the resazurin reduction reaction is observed using single-molecule fluorescence microscopy. The catalytic activity of PdNPs is enhanced by approximately 20 times due to the excitation of localized surface plasmon resonance (LSPR) near the AgNW. The enhancement is also influenced by the wavelength and polarization of the excitation light. Additionally, the catalytic activity of palladium is further enhanced by approximately 10 times in the presence of a roughened AgNW or an AgNW-AgNW nanogap due to improved catalytic hotspots.

Summary: This study investigated the effect of crystal stoichiometric variations on the gas sensing properties of titanium-based MXenes loaded with Pd nanodots. Pd/Ti2CTx exhibited higher sensitivity to H-2, as well as faster response and recovery rates compared to Pd/Ti3C2Tx. The higher resistance change induced by H-2 adsorption in Pd/Ti2CTx was attributed to more effective charge transfer at the heterointerface of Pd/Ti2CTx.
