Colonisation of cerebrospinal fluid shunts by coagulate-negative staphylococci (Staphylococcus albus) is a serious problem. Because of its possible role in prevention of the condition, the antimicrobial activity of silicone rubber after impregnation with antimicrobial drugs was studied. The method of impregnation used and test methods were found to be important. Formaldehyde-urea condensates ga...

The importance of neurofibrillar impregnations in the study of the nervous system needs no emphasis. However, the silver methods currently used involve such a complex of variables that the results are by no means constant. The present communication is devoted to the problem of interpretation of results, together with certain fundamental relations between brain tissue and silver solution. The mo...

An innovative “domino” process, based on an arene hydrogenation followed by a photocatalytic step, was designed for the remediation of endocrine disrupting compounds, in highly concentrated aqueous effluents. The novelty relies use TiO2-supported zerovalent Rh nanoparticles as multicatalytic materials (MCMs) this two-step treatment, applied diethyl phthalate, which is model aromatic pollutant f...

This work presents an economic and simple method to manufacture low cost, but effective adsorbents for CO2 capture through impregnating DETA to a low cost, porous silica gel. The results have demonstrated that the low cost silica gel impregnated by low molecular-weight amine is stable and work very well at a temperature up to 130 C. The developed adsorbent has a fast adsorption kinetics and can...

Ammonia decomposition is a key step in hydrogen production and considered promising practical intercontinental carrier. In this study, 1 wt.% Ru/SiO2 catalysts were prepared via wet impregnation subjected to calcination air at different temperatures control the particle size of Ru. Furthermore, silica supports with surface areas after utilized support change Ru distribution Ru/SiO2. N2 physisor...

In this work, the effect of addition iridium on TiO2 and Nb2O5 supports obtained by wet impregnation method was evaluated in photocatalytic degradation 2,4-dichlorophenoxiacetic acid under UV irradiation. The synthetized materials were analyzed different techniques order to determinate their physicochemical properties. general, it observed that modifies surface area, band gap energy enhances cr...

High surface area and porosity SBA-16 was synthesized used as support for Ni nanoparticles using three methods including wet impregnation, citric acid-assisted ammonia evaporation. All the studied samples showed high activity in CO2 reforming of methane reaction, however, best catalytic behavior found catalyst derived from Based on characterization techniques, it assumed that improvement Ni/SBA...

In this work, the ionic liquid [Aliquat][Cl] was supported into alginate and silica aerogel matrices applied as a catalyst in cycloaddition reaction between CO2 bio-based epoxide (limonene oxide). The efficiency of system is much higher than that one. method wet impregnation used for with zinc complex. procedure originated well-defined thin solvent film on surface support materials. Final mater...

Catalysts based on zirconia and alumina-supported tungsten oxides (3–18 wt% W) with a small loading of platinum (0.3 Pt) were selected to study the influence W loading, support type, preparation methods hydroisomerization n-dodecane. The alumina- zirconia-supported catalysts show different catalytic properties that play an important role in n-dodecane conversion. Specific surface area acidity a...

Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...
