Synthesis and Characterization of Nano-Size CaCO3 via Thermal Treatment and Solid State Method.
CaCO3 nanoparticles have been synthesized via heat-treatment of a new precursor and solid state reaction. Effect of calcinations temperature and quantity of surfactant on particle size has been investigated. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT–IR) spec...
متن کاملSolid-state thermal rectifier.
We demonstrated nanoscale solid-state thermal rectification. High-thermal-conductivity carbon and boron nitride nanotubes were mass-loaded externally and inhomogeneously with heavy molecules. The resulting nanoscale system yields asymmetric axial thermal conductance with greater heat flow in the direction of decreasing mass density. The effect cannot be explained by ordinary perturbative wave t...
متن کاملImpact of Phosphate on Fluoride Removal by Calcite
Fluoride can be removed from wastewater by addition of calcite. However, fluoride is often found in complex mixtures where other contaminants can affect the removal process. Batch experiments were used to determine the impact of phosphate (PO4 3 ) on the removal of fluoride from solution by calcite. In the experiments, up to 2,000 mg/L F and 500 mg/L PO4 3 were used with 150 mm and 1.18 mm calc...
متن کاملRadiological risk assessment of use of phosphate fertilizers in soil
ABSTRACT Background: The radiological impact of the use of phosphate fertilizers in soil is due to the internal irradiation of the lung by the alpha particles, short lived radon-thoron progeny and the external irradiation of the body by gamma rays emitted from radionuclides in situ. This paper describes the results of gamma spectrometric measurements of the concentration ...
