Aniline was synthesized by catalytic hydrogenation of nitrobenzene (NB) on nano-sized Pd on γ-Al2O3 catalyst prepared by sol-gel method. The catalyst was characterized by SEM and XRD. The average ...

Development of simple and reliable protocols for the immobilization of enzymes is an important aspect of nano biotechnology. Silver nanoparticles are known to bind enzymes, but reuse characteristics of the silver nano-enzyme ...

Polyimide-Silica hybrid films with nanostructure were successfully prepared using the sol-gel technique by hydrolysis-polycondensation of tetraethoxysilane (TEOS) in the polyamicacid solution. At the first step polyamic ...

Abstract Natural radioactivity is omnipresent on earth: natural radio nuclides are abundant in all oceans, in the earth's crust and in the atmosphere. Addition to natural resources, many activities ...

Titanium oxide nanotubes were fabricated by anodic oxidation of a pure titanium sheet in 1.5 M H2SO4, 0.3 M H3PO4 and 0.3 M H2O2 mixture solution. The ...

In this paper, simultaneous management of energy and water systems in single contaminant state was considered in two different conditions: (i) systems with only fresh water usage and (ii) systems with ...

Chemical vapor transport (CVT)) is known as one of the most efficient methods of synthesizing nanocrystals. In order to investigate the underlying phenomena in CVT processes, especially the growth rate and growth quality ...
