Chemical Wet Synthesis and Characterization of Copper-SilverNanoparticles
AgCu nanoparticles (NPs) of near-eutectic composition were prepared by various route of wet synthesis. Nanoparticles suspended in nonpolar solvents were synthesized by solvothermal synthesis from metalloorganic precursors. AgCu colloids in aqueous solution were obtained by the hydride reduction of Ag and Cu nitrates u…

Novel Strategies in the Drug Delivery Development of Anticancer Drugs: The Nanoparticulate Formulations
Cytotoxic drugs are a diverse class of compounds that treat cancer primarily by killing cancerous cells that are rapidly growing and dividing along with cells that are meant for normal tissue function. A novel and suitable delivery system delivers the chemotherapeutic agents to cancerous tissues without harming health…
Molecular and Ionic Species in Vapor over Molten Ytterbium Bromides
The vaporization of ytterbium di- and tribromides was studied using high-temperature mass spectrometry over the temperature range 850–1300 K. It was ascertained that the vapor contained the molecules YbBr3, YbBr2, YbBr, Br2, Yb2Br4, Yb2Br5, Yb2Br6, the atoms Yb, and Br, and the negative ions YbBr3− and YbBr4−. The vap…
Ionic Conduction of Oxygen and Calciothermic Reduction in Molten CaO‐CaCl2
Oxygen conductive nature of CaO-CaCl2 melt was confirmed by EMF method at the high oxygen partial pressure, PO2 >10-19 atm at 1073-1173 K, while the stable EMF could not be obtained at the low PO2. A disk of the oxygen conductive La0.8Sr0.2Ga0.8Mg0.15Ni0.05O3 or La0.8Sr0.2Ga0.8Mg0.2O3 was used as the oxygen absorbing…
Conductive Property of Molten Carbonate/Ceria‐Based Oxide (Ce0.9Gd0.1O1.95) for Hybrid Electrolyte
The electrical conductivity and Raman spectra of a Gd-doped ceria (Ce0.9Gd0.1O1.95)/molten (Li/Na)2CO3 composite were investigated concerning the electrolyte materials for intermediate temperature solid oxide fuel cells. Mixed samples of high-purity Ce0.9Gd0.1O1.95 powder and Li/Na binary carbonate (52 : 48 wt%) were…
IN – VITRO INHIBITION OF MINERALIZATION OF URINARY STONE FORMING MINERALS BY GLYCOLIC ACID
The inhibition of mineralisation of urinary stone forming minerals by glycolic acid has been investigated. The inhibition efficiency of different concentration was studied. Increased intake of glycolic acid would be helpful in urinary stone prophylaxis. Glycolic acid acts as ‘protecting agent’. It has been suggested t…
Rechargeable Alkaline Metal Batteries of Amide Salt Electrolytes Melting at Low to Middle Temperatures
Binary and ternary mixed alkaline bis(trifluoromethylsulfonyl) amide (TFSA) and bis(fluorosulfonyl)amide (FSA) salts have been investigated for the electrolytes of rechargeable lithium and sodium batteries. These batteries consist of alkaline metals or their alloys for the negative electrode materials, thermally stabl…
NMR Study of Melts in the System Na3AlF6‐Al2O3‐AlPO4
In this work we address the effects of aluminium phosphate dissolution on speciation in cryolite-alumina melts. We have applied in-situ high temperature NMR spectroscopy in order to determine the nature of the anionic entities in molten Na3AlF6–Al2O3–AlPO4 mixtures up to 65 mol% AlPO4 and 5 mol% Al2O3. Using high temp…
Molecular Dynamics Simulation of SiO2 and SiO2‐CaO Mixtures
The thermophysical properties of molten slags were calculated using a molecular dynamics simulation based on the rigid-ion model. For SiO2 and SiO2-CaO mixtures, the local structure in the liquid state was determined and a rather good agreement was observed with available experimental data. Values of the density of si…
