Summary: In this study, Ag-doped TiO2 nanoparticles were synthesized using the sol-gel method and tested for photocatalytic degradation of methylene blue. The experimental results showed that the addition of a photosensitizer increased the degradation efficiency of TiO2-Ag. A parametric study revealed the optimal photocatalyst dose and methylene blue concentration. Acetone was found to modify the photodegradation mechanism and enhance the degradation performance. The recycling tests demonstrated the high photocatalytic stability of calcined TiO2-Ag material.

Summary: In this work, NiFe2O4@NiO (1:0, 0.9:0.1, 0.7:0.3, 0.5:0.5, and 0:1) nanocomposites were prepared using a co-precipitation process to investigate their structural, dielectric, and optical properties for potential application in wastewater treatment. XRD, FTIR spectroscopy, and TEM were used to study the structural and morphological properties. The particle size was found to increase with nickel oxide content, and the oxidation state was determined using XPS. The impedance, dielectric constant, dielectric loss, and ac conductivity were observed to increase with nickel oxide concentration. The (0.5NiFe(2)O(4)/0.5NiO) nanocomposite exhibited the highest photocatalytic activity, degrading 95.41% of methylene blue dye within 120 min.

Summary: Nanoparticles can be synthesized through conventional methods, but these methods have drawbacks such as toxic chemicals, high temperature and pressure, and high cost. As a result, there is growing interest in green methods that are cost-effective, eco-friendly, and less time consuming. In this study, zinc oxide nanoparticles were synthesized using Grewia asiatica extract under optimized conditions of temperature, concentration, and pH. Various microscopic and spectroscopic techniques were used to characterize the synthesized nanoparticles. The synthesized nanoparticles were spherical in shape with a size range of 28-42 nm. The nanoparticles were then used as catalysts for the removal of a toxic dye, and achieved a degradation rate of 92% in 70 minutes. This research presents a novel ecological approach to the green synthesis of nanoparticles and demonstrates the potential of the synthesized zinc oxide nanoparticles as efficient and environmentally friendly catalysts.

Summary: Silver (I) oxide (Ag2O) nanoparticles (NPs) were synthesized by solution reduction. The Ag2O NPs were characterized using XRD, FTIR, SEM, DRS, and DLS techniques. The results showed the structure, shape, energy gap, and functional group variations of Ag2O NPs. The synthesized Ag2O NPs exhibited a mean hydrodynamic diameter of 171 +/- 82.8 nm in water. The photocatalytic activity of Ag2O NPs towards the degradation of Methylene blue (MB) dye under solar light was tested, and a maximum removal efficiency of 91.5% in 70 min was achieved. The photodegradation data followed pseudo-first-order kinetics with a rate constant of 0.0319 min(-1) and a half-life time of 21.72 min.

Summary: We demonstrate a double Rabi splitting of 348 meV in an Ag nanocavity embedding of methylene blue (MB) dye layer, which is attributed to the equilibrium state of monomer and dimer coexistence in MB dye. By observing different hybridized states at varying dye concentrations and tuning the size of the Ag nanocube, we provide clear evidence of the existence of a multi-mode strong coupling regime.

Summary: A novel coronavirus has impacted the global economy, environment, and social life. During the lockdown period, the concentration of volatile organic compounds (VOCs) significantly decreased, especially for benzene, toluene, ethylbenzene, and m-xylene. Furthermore, the closure of non-traffic sources during the lockdown resulted in improved air quality. However, the lifetime cancer risk for benzene exceeded the prescribed value in the pre- and post-lockdown periods.
