Applicability of Bistetrazole Organic Blowing Agents for Zinc Foams

Applicability of Solid Solution Heat Treatments to Aluminum Foams

Present research work evaluates the influence of both density and size on the treatability of Aluminum-based (6000 series) foam-parts subjected to a typical solid solution heat treatment (water quenching). The results are compared with those obtained for the bulk alloy, evaluating the fulfilment of cooling requirements. Density of the foams was modeled by tomography analysis and the thermal pro...

Microstructural characterization of metal foams: An examination of the applicability of the theoretical models for modeling foams

Establishing the geometry of foam cells is useful in developing microstructure-based acoustic and structuralmodels. Since experimental data on thegeometryof the foamcells are limited,mostmodeling efforts use an idealized three-dimensional, space-filling Kelvin tetrakaidecahedron. The validity of this assumption is investigated in the present paper. Several FeCrAlY foamswith relative densities v...

Plant value of zinc in organic wastes

Applicability of zinc complex of L-carnosine for medical use.

Zinc complex of L-carnosine (L-CAZ; generic name Polaprezinc) is the first drug for oral administration in which zinc plays an essential role. L-CAZ was approved as an anti-ulcer drug of membrane protection type. Characterization of L-CAZ was achieved by various spectroscopic methods along with elemental analysis. Zinc ion coordinates with L-carnosine to form a quadridentate 1:1 complex of poly...

Study nanostructures of semiconductor zinc oxide (ZnO) as a photocatalyst for the degradation of organic pollutants

In the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (ZnO) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. Previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...
