background and objective: although diabetes mellitus is known to be one of the risk factors for dementia but neuropathic changes in the brain of diabetic patients have not been completely revealed. therefore, this research study was done to evaluate structural changes in pyramidal neurons of hippocampal ca1 area of male diabetic rats using golgi-impregnation method. materials and methods: male ...

In our current study, supercritical water impregnation (SCWI) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. The method allows nano-particles to place on support surfaces in extremely dispersed conditions. The silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

Supercritical carbon dioxide (scCO2) is extensively used for extracting chemicals from materials, but the impregnation of materials with using scCO2 has received little attention in comparison. To best our knowledge, most technologies described literature operate by principle diffusion, where yield limited solubility. The objective this exploratory study to prove feasibility an process that can...

We theoretically demonstrated that by the impregnation of Li-decorated IRMOF-10 with Li-coated C(60), the hydrogen storage capacity is improved to be 6.3 wt% and 42 g L(-1) at 100 bar and 243 K. Both the gravimetric and volumetric hydrogen uptakes reach the 2015 DOE target at near ambient conditions.

Generally accepted features of alcoholic fetopathy are delayed maturation and retarded dendritic development of neocortex, hippocampus and cerebellum. The present study investigates the effects of a membrane stabilizing agent (CDP-choline) on Purkinje cells of chronically alcohol intoxicated newborn rat pups, employing a Golgi impregnation technique. Both quantitative and qualitative data indic...

We report an original and scalable synthesis pathway to produce encapsulated gold nanoparticles. Precise control of the gold particles is achieved in the range of 1-10 nm through the impregnation of silicalite-1 with a controlled concentration of gold solution, followed by dissolution-recrystallization of the zeolite.
