a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

Transparent mesoporous silica films were prepared by sol-gel spin coating on silicon wafers at room temperature. An erbium complex, erbium tris 8-hydroxyquinoline (ErQ), was homogeneously impregnated into the pores of the mesoporous silica films, and its concentration was easily controlled by using a solution immersing technique. The ErQ-impregnated mesoporous silica films show a room-temperatu...

The aim of this research was to investigate the potential of raw and iron oxide impregnated carbon nanotubes (CNTs) as adsorbents for the removal of selenium (Se) ions from wastewater. The original and modified CNTs with different loadings of Fe2O3 nanoparticles were characterized using high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffracto...

The present study reports the use of raw, iron oxide, and aluminum oxide impregnated carbon nanotubes (CNTs) for the adsorption of hexavalent chromium (Cr(VI)) ions from aqueous solution. The raw CNTs were impregnated with 1% and 10% loadings (weight %) of iron oxide and aluminum oxide nanoparticles using wet impregnation technique. The synthesized materials were characterized using scanning el...

Effects of alfalfa-intercropping and nanosilver-impregnation were studied here on the specific gas permeability of 10-year old Populus nigra var. betulifolia. Specimens were impregnated with a 200 ppm aqueous dispersion of silver nanoparticles under 250 kPa pressure; the results were then compared with the un-impregnated specimens. The size range of silver nanoparticles was 10 to 80 nm. After t...

In this study, we investigated the color, gloss and surface roughness of bamboo (Phyllostachys bambusoides) and Scots pine (Pinus sylvestris) samples impregnated with boron and copper based preservatives during accelerated weathering from 168 h to 672 h. Tanalith-E, ACQ, wolmanit-CB were used as copper-based chemicals, while a mixture of boric acid and borax (7:3; w/w) was used as the boron com...

The present status of impregnated mosquito nets and other impregnated materials is discussed. Research projects which have produced most of the publications on this subject were conducted in areas in Africa with relatively high endemicity of malaria. In these areas, usage of impregnated mosquito nets caused substantial reductions in the sporozoite inoculation rates and some reduction in inciden...

OBJECTIVE To assess the efficacy of a chlorhexidine-impregnated dressing for prevention of central venous catheter-related colonization and catheter-related bloodstream infection using meta-analysis. DATA SOURCES Multiple computerized database searches supplemented by manual searches including relevant conference proceedings. STUDY SELECTION Randomized controlled trials evaluating the effic...

Purpose: To assess and compare the invivo antibacterial property of Miswak sticks and 0.5% Sodium Fluoride (NaF) impregnated Miswak sticks against Streptococcus mutans (S.mutans) and Lactobacillus. Materials and methods: A randomized controlled clinical trial (parallel group design) was conducted involving 20 subjects who were randomly allocated to Group A (0.5% NaF impregnated Miswak sticks) a...
