Summary: This review discusses the recent advances in the synthesis approaches, fundamental properties, and photocatalytic activity of Cu3N nanostructures. The study found that the synthesis conditions play a crucial role in the shape and size control of Cu3N. Cu3N nanostructures exhibit a narrow bandgap and excellent optical properties, and the presence of Cu and N vacancies on the surface of the nanoparticles contributes to their photocatalytic dye-degradation potential. Additionally, combining plasmonic nanoparticles with other photocatalysts enhances the efficiency of Cu3N.

Summary: SiO2:DAST composites with a porosity of 30-70% were synthesized using evaporation from a solution and temperature lowering methods. X-ray analysis revealed the absence of DAST crystalline phase in the composites. The composites exhibited a single luminescence band with a peak at 620-640 nm after annealing at 100 degrees C. Increasing the annealing temperature to 200 degrees C resulted in a hypsochromic shift of the luminescence band maxima to 590-565 nm and a change in the structure of the composite, including the filling of SiO2 matrix pores due to exfoliation of DAST layers.

Summary: This study measured multiangular photometric and polarimetric hyperspectral field results of snow with different properties, finding that the intensity defined by photometric results was similar to those derived from polarimetric measurements. The bidirectional polarized reflectance factor of snow was found to be useful for characterizing snow properties, and existing BPRF models did not match well with the BPRF measured in the 2 pi space. More attention should be paid to the combination of IpRF (BRF or HDRF) and BPRF for describing the optical properties of light reflected from snow and quantifying snow properties.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
