Summary: The wollastonite-nanoTiO(2) composite, WOT-PC, exhibits promising photocatalytic performance and recycling ability due to the stable chemical binding of Ca-O-Ti and Si-O-Ti, as well as the promotion of electron-hole separation efficiency by Ca-O-Ti. UPS analysis suggests that electron movement to the surface of TiO2 is facilitated after wollastonite supports nanoTiO(2), leading to enhanced photocatalytic performance. The superhydrophilicity and self-cleaning ability of WOT-PC make it a potential candidate for outdoor wall coatings.

Summary: Energy storage is crucial for sustainable development, and phase change materials (PCMs) with high latent heat value have become a hot topic in current research. However, issues such as low thermal conductivity, supercooling, phase separation, and corrosive nature of salt hydrate PCMs need to be addressed. Nano additives offer a solution to overcome these concerns. This review article critically examines the hybridization techniques of metal, carbon, and polymer additives in salt hydrate PCMs, and compares and analyzes the significant variations in the thermophysical properties of salt hydrate with nano additives. Advanced applications of nano additives-based salt hydrate PCMs are also discussed.

Summary: The poor interparticle connectivity between the nanoparticles in the photoanode has been improved by using lead (Pb) as a sintering aid at a low temperature of 150-250 degrees C. The formation of necks at the TiO2-Pb interface improves the connection and reduces electronic resistance. The highest efficiency of 8.73% is achieved with 5 wt% Pb in the TiO2 matrix at 250 degrees C.

Summary: This article introduces a three-phase hybrid multilevel inverter (MLI) with enhanced pulsewidth modulation (PWM) strategy. The proposed MLI combines the series connection of half-bridge and full-bridge for level generation and the T-type inverter for polarity generation. An enhanced PWM strategy reduces complexity and solves high-frequency switching transitions in the existing hybrid MLI modulation method. The proposed MLI can produce 11 levels of output voltage with reduced dc sources requirement. Detailed analyses cover circuit configuration, operating principles and modeling, PWM signals generation, output voltage characteristics, dynamic response, harmonics content, power loss, and voltage stress of power switches. Simulation and experimental results verify the operating principle and functionality of the proposed MLI.
