Lithium cadmium phosphate glasses were prepared by melt quench technique. These glasses contain a mole % composition of x% Li2O-(50-x)% CdO-50%P2O5. The quantity x varies from 0-40 mole%. The physical properties reported in this paper are mass density ρ, modulus of rigidity η, coefficient of linear expansion α, transition temperature Tg, Softening temperature Ts, Oxygen packing density, Molar v...
An asymmetric moissanite anvil cell is used to study aqueous solutions of ammonium iodide at pressures up to 10 kbar. The index of refraction is measured using the rotating Fabry-Perot technique, with an accuracy of approximately 1%. The mass density and molar volume of the solutions are estimated using the measured index values, and the molar volume is used to predict the pressure dependence o...
We report a simple universal method to systematically improve the accuracy of hydration free energies calculated using an integral equation theory of molecular liquids, the 3D reference interaction site model. A strong linear correlation is observed between the difference of the experimental and (uncorrected) calculated hydration free energies and the calculated partial molar volume for a data ...
Changes in Cu and Zn ion levels have been reported in many nervous system disorders such as Alzheimer’s disease, Wilson’s disease and Pick’s disease. The relationship between ion levels and polarization/depolarization of cell membrane is important since ion levels affect the state of polarization and depolarization of the cells. In this study, synaptosomes from different brain areas...
The application of synthetic colors in textile industries and their entry into the water and groundwater is an environmental problem because of being very toxic material. The synthetic colors which are used in textile dyeing (plyacrilic and polyester) are usually dispersing colorants. They derive the azo and anthraquinone chemicals. Electro-Fenton process is an efficient technique which can deg...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
