Gold-gold sulfide nanoparticles are of interest for drug delivery, biomedical imaging, and photothermal therapy applications due to a facile synthesis method resulting in small particles with high near-infrared (NIR) absorption efficiency. Previous studies suggest that the NIR sensitivity of these nanoparticles was due to hexagonally shaped metal-coated dielectric nanoparticles that consist of ...

the objective of this study was to assess the potential of cadmium sulfide nanoparticles loaded onto activated carbon (cdsn-ac) for the removal of sunset yellow (sy) dye from aqueous solution. adsorption studies were conducted in a batch mode varying solution ph, contact time, initial dye concentration, cdsn-ac dose. in order to investigate the efficiency of sy adsorption on cdsn-ac, pseudo-fir...

Metal coated Hollow Glass Waveguides (HGWs) incorporating single dielectric thin films have been widely used for the low-loss transmission of infrared radiation in applications ranging from surgery to spectroscopy. While the incorporation of single dielectric film designs have traditionally been used in metal/dielectric coated HGWs, recent research has focused on the development of alternating ...

In this investigation, we report facile synthesis of cadmium(II)-thioacetamide nanocomposites in the presence and absence of polyvinyl alcohol under ultrasonic irradiations, using cadmium acetate dihydrate (Cd(CH3COO)2.2H2O), potassium iodide (KI), thioacetamide (TAA, CH3CSNH2), and polyvinyl alcohol (PVA) as the starting materials. Results show that in the presence of polyvinyl alcohol size...

Semiconductor-metal hybrid nanostructures offer a highly controllable platform for light-induced charge separation, with direct relevance for their implementation in photocatalysis. Advances in the synthesis allow for control over the size, shape and morphology, providing tunability of the optical and electronic properties. A critical determining factor of the photocatalytic cycle is the metal ...

cadmium sulphide (cds) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. the obtained nanoparticles structures were characterized by x-ray diffraction (xrd) and transmission electron microscopy (tem) whereas optical characterization was done by ultra violet-visible absorption. xrd result shows that cds nanopart...

cadmium oxide (cdo) nanoparticles were prepared by precipitation method using cadmium acetate and ammonia solution. presence of chemical species, were verified by fourier transform infra red (ftir) spectrum. from x-ray diffraction (xrd) spectrum the particle size, d-spacing value and structure of the nanoparticle were analysed. size of the nanoparticles and the elemental composition were detect...
