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...
We report on organometallic synthesis of luminescent (ZnSe/CdS)/CdS semiconductor heterostructured nanorods (hetero-NRs) that produce an efficient spatial separation of carriers along the main axis of the structure (type II carrier localization). Nanorods were fabricated using a seeded-type approach by nucleating the growth of 20-100 nm CdS extensions at [000 +/- 1] facets of wurtzite ZnSe/CdS ...
Morphology-controlled synthesis of CdS can significantly enhance the efficiency of its photocatalytic hydrogen production. In this study, a novel three-dimensional (3D) flower-like CdS is synthesized via a facile template-free hydrothermal process using Cd(NO3)2•4H2O and thiourea as precursors and L-Histidine as a chelating agent. The morphology, crystal phase, and photoelectrochemical performa...
Corporate credit default swap (CDS) premium is the market price of credit risk posed by a corporate obligor. Although corporate CDS are commonly used for risk benchmarking in accounting and credit risk management, liquid CDS are limited to less than 500 corporate names globally. CDS users must either confine their usage to this limited subset or resort to aggregates derived from the liquid CDS ...
cyclodextrins (CDs) is a practical and economical way to improve the physicochemical and pharmaceutical properties of administered drug molecules. CDs can improve properties such as solubility, stability, and bioavailability of various drugs, thereby potentially serving as novel drug carriers. In addition, the hydrophobic and ionizable derivatives of CDs are being tested for use in the preparat...
The ZnO-CdS core-shell composite nanorods with CdS shell layer thicknesses of 5 and 20 nm were synthesized by combining the hydrothermal growth of ZnO nanorods with the sputtering thin-film deposition of CdS crystallites. The microstructures and optical properties of the ZnO-CdS nanorods were associated with the CdS shell layer thickness. A thicker CdS shell layer resulted in a rougher surface ...
A new type of environmentally friendly phosphor based on carbon nanodots (CDs) has been developed through the dispersion of CDs by integrating the CDs with starch particles. The starch particles contain large numbers of hydroxyl groups around the surfaces, which can effectively absorb the CDs, whose surfaces are functionalized by lots of carboxyl and amide groups, through hydrogen bonding. Effe...
Clinical decision support (CDS) within the electronic health record represents a promising mechanism to provide important genomic findings within clinical workflows. To better understand the current and possible future costs of genomic CDS, we leveraged our local CDS experience to assemble a simple model with inputs such as initial cost and numbers of patients, rules, and institutions. Our mode...
We propose an algorithm to determine stable connected dominating sets (CDS) for mobile ad hoc networks using the notion of strong neighborhood (SN). The SN-CDS algorithm takes an input parameter called the Threshold Neighborhood Distance Ratio (TNDR); for an edge to be part of a strong neighborhood-based topology, the ratio of the physical Euclidean distance between the end nodes of the edge to...
Two experiments evaluated the effects of condensed distillers solubles (CDS) on performance and carcass characteristics of finishing beef cattle. In Exp. 1, 250 crossbred steers (initial BW = 355 ± 18 kg) were fed 0, 9, 18, 27, or 36% CDS (DM basis) which replaced a portion of urea and a 1:1 ratio of dry-rolled corn (DRC) and high-moisture corn (HMC). Steers were divided into 3 BW blocks and we...
