By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Phenothiazines are presented in a new report. According to news reporting from Freiburg, Germany, by NewsRx journalists, research stated, "Core/shell CdS/ZnS nanoparticles were modelled in the Material Studio environment and synthesized by one-pot procedure. The core CdS radius size and thickness of the ZnS shell composed of 1-3 ZnS monolayers were predicted from the molecular models."
The news correspondents obtained a quote from the research from the Institute of Materials Science, "From UV-vis absorption spectra of the CdS/ZnS colloid dispersions transition energies of CdS and ZnS nanostructures were calculated. They indicated penetration of electrons and holes from the CdS core into the ZnS shell and relaxation strain in the ZnS shell structure. The transitions energies were used for calculation of the CdS core radius by the Schrodinger equation. Both the relaxation strain in ZnS shells and the size of the CdS core radius were predicted by the molecular modelling. The ZnS shell thickness and a degree of the CdS core coverage were characterized by the photocatalytic decomposition of Methylene Blue (MB) using CdS/ZnS nanoparticles as photocatalysts. The observed kinetic constants of the MB photodecomposition (k(obs)) were evaluated and a relationship between k(obs) and the ZnS shell thickness was derived."
According to the news reporters, the research concluded: "Regression results revealed that 86% of the CdS core surface was covered with ZnS and the average thickness of ZnS shell was about 12% higher than that predicted by molecular modelling."
