Summary: An octahedral CoO@CoS composite structure was successfully designed and prepared, which exhibited a significant improvement in photocatalytic performance for degradation of tetracycline compared to nude CoO. The improved performance is mainly attributed to the incorporation of CoS nanoparticles, which enhance the photo-absorption ability of octahedral CoO and facilitate the transfer and separation of charge carriers.

Summary: This study designed thermodynamically, kinetically, and tentropically stable homogeneous solutions of bovine serum albumin (BSA 66), hemoglobin (Hb 64.5), and double stranded deoxyribonucleic acid (dsDNA 130 kDa) with water and different concentrations of aqueous carboxymethyl cellulose sodium salt (NaCMC). The physicochemical properties of these solutions were studied, and various methods were used to analyze their structural recognition and interaction. The results showed that the interaction mechanism of BSA, Hb, and dsDNA with NaCMC involved salt bridges, electrostatic dipoles, and hydrogen bonds, and these interactions could affect the solubilization of biomolecules. The findings of this study have implications for areas such as biochemical, biophysical, bioengineering, tissue, and genetic engineering, and can be extended to pharmaceutical and cosmetic processes.

Summary: This research aims to develop activated carbon/TiO2 composites with a core-shell structure, where the AC core is covered with a photocatalyst. By modulating the fabrication procedures through mechanical grinding, the spatial distribution of the components can be controlled, preserving their sorption and photocatalytic properties. These core-shell composites offer a double functionality, allowing for accessibility to adsorption sites and maximum light harvesting.

Summary: The main objective of this work was to experimentally confirm the formation of a continuous, substitutional solid solution in the pseudo-binary system YVO4-YbVO4 and investigate its unknown properties as a function of composition. The results show that the solid solution has a structure composed of YVO4 and YbVO4, and its crystalline lattice contracts and energy gap decreases with an increase in the parameter (x). The solid solution is stable in the air atmosphere up to approximately 1500 degrees C and belongs to the semiconductor category.

Summary: Recent developments in fluorescence spectroscopy allow for the measurement of absorption and dispersed fluorescence spectra of isolated molecular ions at low temperatures. Lower temperatures provide narrower spectra and better information on vibronic features. Experiments were conducted on oxazine dyes cooled to around 100 K, and the results showed small Stokes shifts and broader spectra for the darrow-red cations compared to other ionic dyes.

Summary: The MnO2 nanosheet/ZnO microflower coated cotton fabric exhibited potent antimicrobial effects, self-cleaning activity, and photodegradation capabilities under direct sunlight. The high photoactivity was attributed to harnessing photon energies and accelerated charge separation facilitated by the MnO2 nanosheet on the ZnO microflower, showing promising potential for multifarious applications.

Summary: This study investigates the influence of different evaluation methods on the determination of band gap energy (E-g) in semiconductors. By evaluating 32 literature sources and conducting their own experiments, the authors find that the choice of evaluation method can lead to differences in E-g up to 0.87 eV. In the case of P25 loaded with CuO, contradictive effects of metal loading on E-g are observed using different methods. Different phase compositions of TiO2 also yield EM-dependent results. The paper provides recommendations for the use of evaluation methods and highlights common pitfalls in determining E-g via UV/Vis DRS.
