The material source and the evolution of ore-forming hydrothermal fluids Xiaojiashan gold deposits remain controversial. We carried out a mineralogical characteristics analysis, trace elements sulfur isotope composition fluid inclusion microthermometry in order to explore sources, conditions, process this deposit. Gold mineralization can be divided into three stages: quartz-pyrite stage, quartz...

Two amino-terminated amphiphilic copolymers, M600 and M1000, with different ethylene oxide to propylene oxide EO/PO ratios, 1/9 and 19/3, respectively, were coupled by thioctic acid, which allows an excellent affinity with gold surface. Then, amphiphilic thermally responsive gold nanoparticles (AuNPs) were prepared either by ligands exchange on precursor gold nanoparticles or by direct reductio...

the method of weights of evidence is one of the most important data driven methods for mineral potential mapping in gis. in this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. in this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in torbat-e-heydarieh area, east of iran. as a...

The present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. Nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. The prepared nanocapsules were used for controlled drug release of anticancer agents with gold and iron oxide nanoparticles. ...
