The method involves impregnation of fixed embryos with a solution of plexiglass. The solvent is evaporated slowly. Blocks of plexiglass containing the specimen are thus formed. Sections (1-2 microns) are stretched and attached by an unconvential method. Immunohistological techniques allow antigen localization in a combination of high resolution, excellent quality of the sections and low backgro...

Vacuum impregnation is a non-destructive method of introducing a solution with a specific composition to the porous matrices of fruit and vegetables. Mass transfer in this process is a result of mechanically induced differences in pressure. Vacuum impregnation makes it possible to fill large volumes of intercellular spaces in tissues of fruit and vegetables, thus modifying physico-chemical prop...

The Golgi methods have long been used to study the neuronal soma, axons, dendritic arborization and spines. The major concerns of the Golgi method have been its unpredictable nature (inconsistency of impregnation of the stain), time consumed, tissue hardening and clear background, resulting in several modifications to improve the cellular visualization. In the present work we describe a modific...

The effectiveness of Mg as a promoter of Co-Ru/γ-Al2O3 Fischer-Tropsch catalysts depends on how and when the Mg is added. When the Mg is impregnated into the support before the Co and Ru addition, some Mg is incorporated into the support in the form of MgxAl2O3+x if the material is calcined at 550°C or 800°C after the impregnation, while the remainder is present as amorphous MgO/MgCO3 phases. A...

Ganglia processed through the osmium-ethyl gallate procedure (OEG) 19 retain more structural integrity than those processed through various silver impregnation methods. However, the OEG method continues to be neglected by most neuroanatomists. Both types of procedures have been used to trace large neuronal tracts, but during silver impregnation the neuropils lose many of their identifying chara...

Information on the influence of impregnation of cementitious slurry at the soil-structure interface of bored cast in-situ foundation is inadequate in available literatures. Moreover, influence of such impregnation on negating the detrimental effects of smear zone, formed by construction tools, surrounding the borehole is also unknown. In classical foundation engineering, influences of smear and...

Copper azole type B (CAz-B) preservative and polyphosphatic carbamate (PPC) fire retardants were impregnated in succession into green (97% MC) and kiln-dried (18% MC) Japanese cedar (Cryptomeria japonica (L.f.) D.Don) lumber by the passive impregnation method to prolong the period of lumber use by increasing its resistance to fire and biological degradation. Lumber was dried with a kiln or by a...

The catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. The catalyst was prepared by the wet impregnation method and characterized by using the Brunauer Emmett Teller (BET), field emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Temperature-programmed reduction (TPR) analysis. The highest catalytic ...

Electrocatalysis of oxygen reduction using Pt nanoparticles supported on functionalized graphene sheets (FGSs) was studied. FGSs were prepared by thermal expansion of graphite oxide. Pt nanoparticles with average diameter of 2 nm were uniformly loaded on FGSs by impregnation methods. Pt-FGS showed a higher electrochemical surface area and oxygen reduction activity with improved stability as com...
