Summary: Water-evaporation-induced generators (WEIGs) are environmentally friendly power sources, but they traditionally have weak power outputs. This study introduces C/metal and metal/metal WEIGs, which utilize the Galvanic corrosion of metals to significantly enhance the power output of WEIGs. The study also demonstrates that the asymmetric environments and potential differences between the two electrodes in a WEIG can facilitate metal corrosion and the fabrication of compact Galvanic WEIGs.

Summary: A high-hardness coating can resist ice adhesion, while a soft coating is prone to ice shedding. A bilayer polyurethane coating was developed that achieved both high hardness and low ice adhesion strength. Another bilayer coating with a diamine, epoxy compound, and poly(glycidyl methacrylate) with poly(dimethylsiloxane) side chains was prepared to maintain consistently low ice adhesion strength over numerous icing/deicing cycles. This study compared the ice-shedding properties of different lubricated coatings and found that the smooth bilayer epoxy coating, lubricated with a silicone oil mixture, maintained low ice adhesion strength even after 30 icing/deicing cycles.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
