The durability of platinum nanoparticles is investigated to determine the way in which particle size and oxygen coverage affect their reconstruction under gas-phase conditions oxidizing environments. Classical molecular dynamics simulations are performed using third-generation charge-optimized many-body potential, findings compared experimental measurements. diameters range from 1.35 nm 11.29 n...
Recent studies of catalysis have highlighted the importance heat-driven reaction enhancement, suggesting need for improved understanding heat transfer in vicinity catalyst particles process. Specifically, it is essential and necessary to understand transferred surrounding gas molecules surface. In present study, we developed a method estimate ratio particle framework ReaxFF. A molecular dynamic...
Platinum extraction from spent reforming catalysts in iodine solutions under atmospheric pressure at different temperatures, acid concentration, and iodine spices concentration, catalyst particle size, and impeller agitation speed have been studied in our group. In this system, platinum is oxidized from spent catalyst with I3¯ that is formed ...
Background and purpose: Chemotherapy with platinum-base cytotoxic drugs (PBCDs) are commonly used in treatment of different types of cancers. Significant amounts of these drugs enter the hospital effluent via urinary exertion of patients and could adversely affect the environment and different ecosystems. Materials and methods: The samples (n=7) of 24 hours' hospital effluent were collected...
