Spontaneous formation of cadmium hydroxide nanostrands in water.
Cadmium hydroxide nanostrands with a diameter of 1.9 nm were spontaneously formed by raising the pH of a dilute Cd(NO3)2 solution. The length reaches a few micrometers and the aspect ratio exceeds 1000. The crystallographic structure was successfully elucidated by high-resolution electron microscopy. The surface of the nanostrands was remarkably positively charged and adsorbed an astonishing nu...
متن کاملA Simple Method to Synthesize Cadmium Hydroxide Nanobelts
Cd(OH)2 nanobelts have been synthesized in high yield by a convenient polyol method for the first time. XRD, XPS, FESEM, and TEM were used to characterize the product, which revealed that the product consisted of belt-like crystals about 40 nm in thickness and length up to several hundreds of micrometers. Studies found that the viscosity of the solvent has important influence on the morphology ...
متن کاملCalcium Chloride Extractable Cadmium as an Estimate of Cadmium Uptake by Subterranean Clover
Cadmium (Cd) ) may accumulate in soils which have been regularly fertilized with phosphate fertilizers which contain Cd originating in rock phosphate. Soil was taken from three sites in the wheatbelt of Western Australia which were estimated to have received different amounts of phosphate fertilizer over the past decade. The pH was adjusted with dilute HCl or CaC03. No Cd was added experimental...
متن کاملCalcium Hydroxide Crops
Calcium hydroxide was petitioned for use as a soil amendment to supply calcium for crops. Calcium hydroxide (also known as hydrated lime) is produced from the slow addition of water to crushed or ground quicklime (calcium oxide), which is produced by burning various forms of limestone. It may also be produced as a by-product of industrial processes such as from the generation of acetylene from ...
متن کاملIn Vitro Evaluation of Calcium Ions Diffusion and ph Changes of the Periradicular Environment with Conventional Calcium Hydroxide and Synthetic Nanoparticle Calcium Hydroxide as an Intra-Canal Medicament
Background and Aim: Therapeutic effects of calcium hydroxide as an intra-canal medicament depend on its decomposition into hydroxyl and calcium ions. The aim of this study was to determine the diffusion amount of calcium ion and ph changes around the tooth root in the application of conventional calcium hydroxide and Nano particle calcium hydroxide at different times. Material and Methods: In ...
