ZnO/CdS heterostructured nanocomposites were fabricated with enhanced light harvesting capability and photostability using sequential sonochemical and hydrothermal methods from ZnO rods and particles. Interestingly, in the composite made up of CdS sensitized ZnO rods, both ZnO and CdS exist in the hexagonal wurtzite form with different morphologies. On the other hand, in the composite made up o...

CdS and WO3 (CdS/WO3) bilayer film electrodes are fabricated to harness solar visible light (λ > 420 nm) and store photogenerated electrons for possible use during periods of unavailable sunlight. The overall film thickness is approximately 50-60 μm, while the CdS underlayer is slightly thinner than WO3 owing to a packing effect. The energetics of CdS and WO3 determined by optical and electroch...

Amphiphilic block copolymer poly(isoprene-b-acrylic acid) (PI-b-PAA) was used to stabilize exfoliated graphene in water, allowing the immobilization of semiconductor CdS nanoparticles forming CdS • PI-b-PAA/graphene. Characterization using high-resolution transmission electron microscopy and energy-dispersive x-ray spectroscopy proved the success of the preparation method and revealed the prese...

Many people studied the Minimum Connected Dominating Set (MCDS) problem to introduce Virtual Backbone (VB) to wireless networks. However, many existing algorithms assume a static wireless network, and when its topology is changed, compute a new CDS all over again. Since wireless networks are highly dynamic due to many reasons, their approaches can be inefficient in practice. Motivated by this o...

The objective of this research was to study the effect of fat concentration from corn coproducts, fed during the growing phase on DMI, gain, carcass traits, digestibility, and rumen metabolism of steers. Exp. 1: 40 steers (age = 140d; BW = 185 ± 11 kg) were randomly allotted to 1 of 5 dietary treatments: (1) corn-based control (CNT), (2) 0% corn distillers solubles (CDS), (3) 10% CDS, (4) 19% C...

Figure S1. Photoluminescence spectra of CdSe/CdS nanocrystals (NCs) in (a) nanocrystal conjugate, linked with thioglycolic acid (TGA), upon correction for the contribution from Ga2O3 NC emission, (b) pure CdSe/CdS nanocrystal suspension, and (c) mixture of Ga2O3 and CdSe/CdS NCs without the TGA linker. The concentrations of CdSe/CdS NCs are identical in all panels, and are expressed in (a) as a...

A large area arrays (ca. 40 cm(2)) of CdS nanotube on silicon wafer are successfully fabricated by the method of layer-by-layer deposition cycle. The wall thicknesses of CdS nanotubes are tuned by controlling the times of layer-by-layer deposition cycle. The field emission (FE) properties of CdS nanotube arrays are investigated for the first time. The arrays of CdS nanotube with thin wall exhib...

The main goal of this work was to synthesize CdSe/CdS (core-shell) nanoparticles stabilized by polymer ligand using entirely aqueous colloidal chemistry at room temperature. First, the CdSe core was prepared using precursors and acid-functionalized poly(vinyl alcohol) as the capping ligand. Next, a CdS shell was grown onto the CdSe core via the layer-by-layer technique. The CdS shell was formed...

The desired control of particle size, doping element composition, and surface structure of carbon dots (CDs) are vital for understanding the fluorescence mechanism and exploring their potential applications. Herein, nitrogen-doped CDs (N-doped CDs) have been synthesized with tartaric acid and various alkylol amines (monoethanolamine, biethanolamine and triethanolamine) under microwave irradiati...
