We report the synthesis of several unconventional 0-, 1- and 2-dimensional copper sulfide nanostrucutures by the chemical vapor deposition method. The key factor for morphology and structure control of a variety of copper sulfide products is the tuning of deposition and growth temperature to fit for the surface energy barriers and promote different growth directions. At a high growth temperatur...

Three experiments involving 296 pigs were conducted to determine the related effects of copper sulfate and ferrous sulfide on performance and liver copper and iron stores of growing-finishing pigs, and the effect of ferrous sulfide on the depletion of copper from the liver. The dietary addition of 250 ppm copper alone improved growth rate by 9.2% (621 vs 678 g/day) and feed to gain ratio by 3.3...

Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreased leaf AsA,...

Recent advances in nanotechnology could facilitate the production of cheaper solar cells. This review describes synthetic routes to various nanostructured materials that are potentially useful in photovoltaic applications. We have focused on materials that are based on earth abundant elements and/or those that are held to have lower toxicity. Methods to synthesize binary chalcogenides with vari...

The electrochemical behavior of copper electrode in 2M potassium sulfide solution was studied using cyclic voltammograms and potentiostatic polarization techniques. The morphology studies were applied using scanning electron microscope (SEM) and energy dispersive analysis of X-rays (EDAX) and X-ray powder diffraction. Three anodic peaks were observed in the anodic scan of cyclic voltammograms. ...

The conditional stability constants of metal–sulfide complexes were determined in pH 8 seawater at various salinities, by Ž . flow-analysis with detection by cathodic stripping voltammetry FA-CSV . Two methods were used. The first method was titration of the sulfide by metal with detection of the free sulfide by FA-CSV. The titrant metals were Ag, Cd, Co, 2q 2q 2q 2q 3q 3q Ž . Fe , Mn , Pb , Zn...

  Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreas...

By integrating high imaging sensitivity and high resolution in a single modality, photoacoustic (PA) imaging emerges as a promising diagnostic tool for clinical applications. Benefiting from the absorption in the near-infrared region (NIR), copper sulfide nanoparticles (NPs) as a contrast agent are potentially useful for increasing the sensitivity of PA imaging. However, the aqueous synthesis o...

Inorganic nanocrystals have attracted widespread attention both for their size-dependent properties and for their potential use as building blocks in an array of applications. A complete understanding of chemical transformations in nanocrystals is important for controlling structure, composition, and electronic properties. Here, we utilize in situ high-resolution transmission electron microscop...

The growth of crystalline copper sulfide using a viral template was investigated using sequential incubation in CuCl2 and Na2S precursors. Non-specific electrostatic attraction between a genetically-modified M13 bacteriophage and copper cations in the CuCl2 precursor caused phage agglomeration and bundle formation. Following the addition of Na2S, polydisperse nanocrystals 2-7 nm in size were fo...
