Profound understanding and survey of magnesium base intermetallic compounds is hindered by various difficulties in their processing and fabrication. Solid-state synthesis via the bulk mechanical alloying (BMA) is free from contaminations and segregation through high reactivity of elemental constituents against crucibles or vials. Magnesium–tin system is employed to demonstrate the solid-state r...

A review of the many uses of matrix solid phase dispersion (MSPD) in the extraction and analysis of a variety of compounds from a range of samples is provided. Matrix solid phase dispersion (MSPD) has found particular application as a somewhat generic analytical process for the preparation, extraction and fractionation of solid, semi-solid and/or highly viscous biological samples. Its simplicit...

The ability to modify and control the radial electric field and its radial derivative can lead to direct control of radial transport of plasma in a toroidal device. In the DIII-D tokamak, the injection of deuterium pellets is being investigated as a means of controlling the toroidal rotation velocity and the radial electric field, Er. Solid deuterium cylindrical pellets of 1.8mm and 2.7mm diame...

Aim: To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of Olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. Characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...

Mass spectrometric studies of the vapours over solid lead oxide in a flow of gaseous arsenic and antimony trioxides were conducted. The following ions of the ternary oxides were detected: Pb3As2O6(+), Pb3AsO4(+), PbAs2O4(+), PbAsO2(+), PbSb2O4(+), and PbSbO2(+). The origin of these species produced by the ionisation and/or fragmentation of ternary gaseous oxides is discussed. The PbAs2O4 specie...

a mathematical model is described and applied for adsorption process of ethyl acetate from supercritical co2 stream on activated carbon particles. this model has the ability of illustrating variation of effluent concentration towards different parameters such as flow rate, temperature and pressure. in this research, a vast area of operational conditions is experienced. mass transfer resistance ...

The present study aimed to investigate the effect of Eudragit® E/HCl (E-SD) on the degradation of sirolimus in simulated gastric fluid (pH 1.2) and to develop a new oral formulation of sirolimus using E-SD solid dispersions to enhance oral bioavailability. Sirolimus-loaded solid dispersions were fabricated by a spray drying process. A kinetic solubility test demonstrated that the sirolimus/E-SD...

The phase diagram of the ternary system Sr/Mo/O has been determined at a temperature of 1000°C. Powder samples of the ternary compounds SrM o04, Sr3M o06, SrMo03, Sr2M o04 and SrMo50 8 were prepared by solid state reactions. The thermochemical data of all ternary compounds were determined.oA new compound, Sr3Mo20 7, with a layered perovskite structure (a = 3.967(1), c = 20.588(5) A, I4/mmm) was...
