The structural relationship between the parent and product phases in martensitic transformation from ? phase is described. atomic movements leading to martensite are accomplished by a long-range shear {112} < 111 > that transforms lattice short-wavelength displacement or shuffle {110} 110 induces correct stacking. microstructures arising out of these paths depend on which modes initiates transf...

The incorporation of lipophilic nutrients, such as astaxanthin (a fat soluble carotenoid) in nanodispersion systems can either increase the water solubility, stability and bioavailability or widen their applications in aqueous food and pharmaceutical formulations. In this research, gelatin and its combinations with sucrose oleate as a small molecular emulsifier, sodium caseinate (SC) as a prote...

Bi2Te3 thermoelectric materials are utilized for refrigeration for decades, while their application of energy harvesting requires stable thermoelectric and mechanical performances at elevated temperatures. This work reveals that a steady zT of ≈0.85 at 200 to 300 °C can be achieved by doping small amounts of copper iodide (CuI) in Bi2Te2.2Se0.8-silicon carbide (SiC) composites, where SiC nanodi...

BACKGROUND The emulsification-evaporation method was used to prepare astaxanthin nanodispersions using a three-component emulsifier system composed of Tween 20, sodium caseinate and gum Arabic. Using Response-surface methodology (RSM), we studied the main and interaction effects of the major emulsion components, namely, astaxanthin concentration (0.02-0.38 wt %, x1), emulsifier concentration (0...

The fabrication of drug nanoparticles (NPs) with process-mediated tunable properties and performances continues to grow rapidly during the last decades. This study investigates the synthesis and phase tuning of nanoparticulate itraconazole (ITR) mesophases using quasi nanoemulsion precipitation from acetone/water systems to seek out an alternative pathway to the nucleation-based NP formation. I...

Lowering Intraocular pressure (IOP) is a main therapeutic objective in glaucoma patients because IOP an important risk factor for progression. The of this work was to formulate and evaluate, vitro vivo, stable effective Solid Oil (S/O) topical formulation the antiglaucoma drug, timolol maleate (TM). S/O dispersions were prepared by emulsification aqueous TM solutions cyclohexane using different...

A novel nanocrystal system of montelukast (MTK) was designed to improve the transdermal delivery, while ensuring chemical stability labile compound. MTK Nanogel fabricated using nano dispersion method (Modified emulsification diffusion method). In pre-formulation study, there not any physicochemical interaction between drug and polymer had been evaluated by FTIR. The melting point found be 134-...
