TL;DR: In this paper, a series of ceria-supported gold catalysts (1 and 4% Au) were prepared by deposition-precipitation with urea, and the results showed that the higher the fraction in metallic gold is, the better the catalytic performances are.

TL;DR: The kinetics of wet air oxidation of glyphosate was studied in an autoclave reactor at a temperature range of 423-523 K and under a total pressure of 15 MPa, and a degradation pathway for glyphosate oxidation was proposed.

TL;DR: In this article, a shell of iron oxide is formed around a shrinking core of pyrite, and the overall rate of the reaction seems to be controlled by diffusion of dissolved oxygen through the shell.
Abstract: Particles of iron pyrites can be desulfurized by leaching them with a hot alkaline solution containing dissolved oxygen under pressure. As the reaction proceeds sulfur is extracted largely as soluble sulfates, and a shell of iron oxide is formed around a shrinking core of pyrite. The overall rate of the reaction seems to be controlled by diffusion of dissolved oxygen through the shell of iron oxide.

TL;DR: In this article, a continuous process for wet oxidation of aqueous liquor containing combustible matter using oxygen or oxygen enriched gas is described, where an inert diluent gas is injected into the aiquous liquor or reactor off-gas such that oxygen in the gas phase is diluted by the sum of generated water vapor, produced carbon dioxide and injected inert gas to a concentration less than required for spontaneous combustion at every location in the system having surfaces not continually exposed to a continuous liquid water phase.

TL;DR: In this article, a hybrid organic-inorganic solar cell following an inverted bulk heterojunction configuration was fabricated based on the lotus-like ZnO structures, which achieved a power conversion efficiency of up to 1.18% which demonstrates the applicability of the technique for photovoltaic applications.
Abstract: Zinc oxide (ZnO) nanostructures with various morphologies (pencil-like nanorods, nanotubes, and lotus-like structures) have been successfully formed by simple oxidation of vacuum deposited Zn thin film on glass/ITO substrates in hot water at 90 °C. The morphology evolved from pencil-like nanorods to nanotubes to lotus-like structures with prolonged oxidation of Zn thin film for 6–24 h. The change in morphology of ZnO is attributed to the combined effects of electrochemical reactions in the solution, morphology and structure of Zn thin film, and wurtzite structure of resulting ZnO. A hybrid organic–inorganic solar cell following an inverted bulk heterojunction configuration was fabricated based on the lotus-like ZnO structures. The solar cell achieved a power conversion efficiency of up to 1.18%, which demonstrates the applicability of the technique for photovoltaic applications.
