A novel composite adsorbent, Silica aerogel activated carbon was synthesized by sol-gel process atambient pressure drying method. The composite was characterized by Fourier transform infraredspectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry(DSC) and Nitrogen adsorption / desorption isotherms (BET).In the present study, the mentioned adsorbent was used m...

background and aim(s): it is highly important for dentists to be aware of the effects of bleaching agents on the surface and mechanical properties of restorative materials. so, the aim of this in vitro study was to evaluate the effects of different bleaching strategies on the microhardness of a silorane-based composite resin. materials and methods: eighty samples of a silorane-based composite r...

background and aim: in vitro studies have revealed a direct association between resin content and cytotoxicity of resin composites; but implantation studies in this regard are sparse. this study investigates the relationship between filler content of composite resins and biocompatibility. materials and methods: this study was conducted using 18 male wistar rats (180-200g), 1 nano-hybrid (prime-...

One effort to increase the photocatalytic activity of TiO2 is immobilize it on surface sorbent material. This study aims produce TiO2-Activated Carbon (TiO2-AC) composites which have higher than TiO2, using a simple method. The synthesis TiO2-AC was carried out hydrothermal process initiated by mixing TTIP, ethanol, H2O, and activated carbon with various masses (5 g, 10 15 20 g). mixture then p...

Natural composite biomaterials are good structural supports for bone cells to regenerate lost bone. Here, we report that a chitosan-collagen composite film accelerated osteoblast proliferation, differentiation and matrix mineralization in MC3T3-E1 cells. Intriguingly, we observed that the film enhanced the phosphorylation of Erk1/2. We showed that the chitosan-collagen composite film increased ...

Composite electrodes which comprise a activated carbon of large surface area(1600m/g) and a conductive carbon nanotubes(CNTs) of small surface area (200m/g) have been prepared by electrostatic spray deposition and investigated for their capacitive properties in aqueous H2SO4 electrolytes. With the addition of sonochemically well dispersed CNTs to the activated carbon, equivalent series resistan...

Abstract This study investigated removal mechanisms, thermodynamics, and interferences of phosphorus adsorption onto nanoscale zero-valent iron (nZVI)/activated carbon composite. Activated was successfully used as support for nZVI particles to overcome shortcomings using include its tendency aggregate separation difficulties. A comprehensive characterization done the composite particles, which ...
