Current analytical techniques for characterizing solid-state pharmaceuticals include powder x-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, infrared spectroscopy, Raman spectroscopy, electron microscopy and nuclear magnetic resonance. Powder x-ray diffraction and differential scanning calorimetry are mainstream techniques but they lack spatial resolution. Scann...

An alumina–zirconia composite containing 5 mol% zirconia was prepared by following a wet interaction process in aqueous medium via the sol–gel route. The formed hydrogel which was aged for proper growth and orientation at room temperature, was then dried at a low temperature to minimize agglomeration. The sol–gel derived precursor powder was properly characterized through determination of surfa...

The influence of SnO2 nanoparticles and method of their introduction in silver matrix on microstructure and physical properties such as density, porosity, hardness and electrical conductivity of Ag-SnO2 electrical contact materials were studied. The SnO2 nanoparticles were introduced by conventional powder mixing and by template method using different templates. All investigated samples were pr...

Curcumin is a polyphenol that is commonly used for its perceived health benefits. However, the absorption efficacy of curcumin is too low to exhibit beneficial effects. We have successfully developed a highly absorptive curcumin dispersed with colloidal nano-particles, and named it THERACURMIN. The absorption efficacy of THERACURMIN was investigated and compared with that of curcumin powder. Th...

Abstract Influence of nano-glass powder on physico-mechanical properties geopolymer composite materials has been studied, in addition to studying their firing stability against high temperature from 500 up 1000 °C. For increasing mechanical, physical as well for metakaolin composites; Nano-glass was used. Alumino-silicate are kaolin, fired kaolin (metakaolin) and limestone all pass 75 µm. Mater...

Nano-Y2O3 reinforced Ti-47.7Al-7.1Nb-(V, Cr) alloy was fabricated by a powder metallurgy route using spark plasma sintering (SPS), and the influence of nano-Y2O3 contents on microstructure mechanical properties were investigated systematically. The results revealed that ultimate tensile strength elongation 570 ± 28 MPa 1.7 0.6% at 800 °C, 460 23 6.1 0.4% 900 °C with no nano-Y2O3, 662 24 5.5 0.5...

A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...

One of the unifying factors for all countries is large consumption chicken, and other, eggs in food other types economic activity. After using various their intended purpose, a amount waste accumulates form eggshells. Currently, this problem exists needs non-trivial, original solution. The aim work was to fill scientific gap direction studying microstructure formation improved nano-modified env...
