The design of catalytic materials for NOX removal by the selective reduction with NH3 (NH3-SCR) has been a focus research in field waste gas treatment. In this work, pitch-based activated carbon fibers (ACFs) were impregnated copper nitrate and cerium nitrate, then ACFs that loaded bimetallic nanoparticles (ACF@Cu/Ce) obtained after pyrolyzation performed. Moreover, ACF@Cu/Ce furtherly treated ...

FIGURE 5. Suppression of regrowth on prepped subclavian sites with the two CHG-impregnated dressings in healthy volunteers. At day 7, the new integrated CHG transparent dressing showed significantly lower regrowth post prep compared to the control (p<0.0001). At day 10, both CHG dressings showed significantly lower regrowth (p<0.0003). There was a statistically significant difference between th...

BACKGROUND & OBJECTIVES The use of pyrethoid impregnated bednets is one of the main malaria vector control strategies worldwide. The objective of the present study was to evaluate the bioefficacy of bednets impregnated with various pyrethroids after repeated washings. METHODS The effectiveness of bednets impregnated with permethrin, deltamethrin, bifenthrin, etofenprox and long-lasting bednet...

Although glutaraldehyde is known to be bactericidal in solution, its potential use to create novel antibacterial polymers suitable for use in healthcare environments has not been evaluated. Here, novel materials were prepared in which glutaraldehyde was either incorporated into polyurethane using a simple "swell-encapsulation-shrink" method (hereafter referred to as "glutaraldehyde-impregnated ...

OBJECTIVES Direct-filling resin composites are used in relatively small restorations and are not recommended for large restorations with severe occlusal-stresses. The aim of this study was to reinforce composites with fiber preforms, and to investigate the effects of layer thickness and configurations on composite properties. It was hypothesized that fiber preforms would significantly increase ...

evaluated under laboratory condition. the objective of the present study was to observe the effect of impregnated torn bednets on the number of bites by an. culicifacies a glass made tunnel test was designed to the effect of torn bednets treated with three dosages of cyfluthrin 5% ew, were induce hungry female mosquitoes to pass through holes cut in the pyrethroid treated nets. a guinea pig use...

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...

BACKGROUND The search for more eco-friendly acaricides has prompted testing of medicinal plants from botanical sources. OBJECTIVE To evaluate the eradication of house dust mites (HDM), Dermatophagoides pteronyssinus, by direct contact using the essential clove oil (Eugenia caryophyllus). METHODS A pilot study was initiated to determine the killing power of clove oil. Synthetic fibers were i...

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...
