A simple and sensitive method for quantification of nanomolar copper with a detection limit of 1.2×10(-10)M and a linear range from 10(-9) to 10(-8)M is reported. For the most useful analytical concentration of quantum dots, 1160μg/ml, a 1/Ksv value of 11μM Cu(2+) was determined. The method is based on the interaction of Cu(2+) with glutathione-capped CdTe quantum dots (CdTe-GSH QDs) synthesize...

Reductive removal by hydrogeneration using supported Pd/M (M= Cu, Pt, Ag, Co, Fe, Mo, Ni, Rh, Ir, Mn and Cr) bimetallic catalysts has emerged as a promising alternative for nitrate removal in drinking water [1]. Fundamental understanding how the atomic arrangement of Pd and a second element, such as Cu, affect the activity nitrite reduction and selectivity of dinitrogen will be accomplished by ...

Copper (Cu) is an essential element required by all living organisms, since at least 30 enzymes are known to use Cu as a cofactor. Cu is also toxic in excess and liver and gills are known to be target organs for it. In the present study, 240 Siberian sturgeon juvenile (with initial weight 29.2 ± 3.1 g and initial length 21.8 ± 1.4 cm) were randomly distributed in 12 fiberglass tanks at 4 differ...

Carbon dots or carbon nanoparticles (CNPs) are unique class of nanocarbons with photoluminescence property. Considering the biocompatibility CNPs, versatile biological applications have been documented including augmentation in photosynthesis. Significant attention has also paid towards electron donor-acceptor property industrial importance was increased too. Despite some scattered efforts CNPs...

Here, we have used a simple method for polyol synthesis, analysis, and testing of Au/Cu-doped ZnO Ultraviolet (UV) photodetectors (PD). Our results are reported discussed by X-ray diffraction (XRD) to ensure that the manufactured samples show hexagonal wurtzite structure. Transmission electron microscopy (TEM) confirmed nanoparticle growth in sample on surface, which is key improving light resp...
