The integration of diagnostic and therapeutic functionalities into one nanoplatform shows great promise in cancer therapy. In this research, manganese (II) chelate functionalized copper sulfide nanoparticles were successfully prepared using a facile hydrothermal method. The obtained ultrasmall nanoparticles exhibit excellent photothermal effect and photoaoustic activity. Besides, the high loadi...

We will develop rapid screening tools to measure wastewater composition and correlate bulk composition measures to nitrification inhibition. Initially, we will focus on metals (cadmium, zinc, nickel and copper, which have been implicated in nitrification inhibition, moderate to high toxicity to nitrifying microorganisms. Prior to the start of the monitoring study, we will optimize and validate ...

A cross-comparison of six strains isolated from two different regions, Chambishi copper mine (Zambia, Africa) and Dexing copper mine (China, Asia), was conducted to study the leaching efficiency of low grade copper ores. The strains belong to the three major species often encountered in bioleaching of copper sulfide ores under mesophilic conditions: Acidithiobacillus ferrooxidans, Acidithiobaci...

Cu2O hierarchical nanostructures with different morphologies were successfully synthesized by a solvothermal method using copper (II) nitrate trihydrate (Cu(NO3)2⋅3H2O) and ethylene glycol (EG) as initial reagents. The obtained nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area test, and UV-vis spe...

Seasonal and spatial variations in metal concentrations and pH were found in a stream at a restored copper mine site located near a massive sulfide deposit in the Foothill copper-zinc belt of the Sierra Nevada, California. At the mouth of the stream, copper concentrations increased and pH decreased with increased streamflow after the onset of winter rain and, unexpectedly, reached extreme value...

The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It found that an iron-oxidizing strain acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching sulfide from deposits Russia’s Murmansk region. Sulfide mineralization studied mineral feeds described using methods X-ray phase analysis and optical microscopy. In process ...

Copper indium gallium sulfide, CuIn1-xGaxS2 (CIGS2) solar cells prepared with chemical bath deposited heterojunction partner zinc-cadmium sulfide (ZnxCd1-xS) layer has exhibited better blue photon response and in turn, higher currents. This can be attributed to its higher bandgap than that of CdS. The open circuit voltages for CIGS2/ZnxCd1-xS were also higher than those of the CIGS2/CdS devices...

The title compound, [Cu(C(11)H(11)N(4)O(2))(2)], was prepared by solvothermal synthesis using 2-amino-5-(4-methoxy-phen-yl)-1,3,4-oxadiazole and copper sulfate penta-hydrate in an acetonitrile solution. The Cu(II) atom lies on an inversion center and is four-coordinated in a slightly distorted square-planar geometry by four N atoms of the ligands obtained from the formation of a bond between th...

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...
