Polyacrylonitrile (PAN)-oxime-nano Fe2O3 was used as an adsorbent for the removal of fluoride from water. The influences of contact time, initial fluoride concentration, and adsorbent dosage were investigated by batch equilibrium studies. The rate of adsorption was rapid with equilibrium being attained after 100min. The Langmuir isotherm model was found to represent the measured adsorption data...

The present study focuses on the use of Corn cob as an effective and efficient adsorbent for the removal of Ni (II) from aqueous solution. The influence of Physico-chemical parameters such as Adsorbent Dosage, Contact time, pH and Initial concentration has been examined in Batch studies. The initial and residual concentration of Ni (II) was analyzed using UVDouble Beam absorption spectrophotome...

A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.

The study demonstrates two approaches in formulation of solid oral lipid-based diazepam preparations (BCS class II drug). The aim of the study was to formulate tablets and hard capsules, using emulsifier and adsorbent. Lipidbased preparations improve drug solubility and permeability, i. e. bioavailability. Solid silicate carriers are able to adsorb liquid lipid formulations, resulting in freely...

With attention to the thin film structure of colloidal quantum dot solar cells, in this paper in order to improvement of active layer absorption of them, we have proposed the use of nanostructure pattern for enhancement of their performance. For this purpose we have presented suitable nano hemisphare patterns in colloidal quantum dot solar cells for light trapping in absorption layer. Then with...

The presence of elevated concentration of arsenic in water sources is considered to be health hazard globally. Calcination process is known to change the surface efficacy of the adsorbent. In current study, five adsorbent composites: uncalcined and calcined Fe3O4-HBC prepared at different temperatures (400°C and 1000°C) and environment (air and nitrogen) were investigated for the adsorptive rem...

The Cowan I strain of the bacterium Staphylococcus aureus has been used as an adsorbent for antibodies complexed with radiolabeled antigens from cell lysates. This application is advanced as a superior alternative to other methods of immune precipitation for the isolation of antigens. It exploits the high adsorption capacity for IgG molecules by protein A molecules on the cell walls of certain ...

This study presents the preparation and characterization of chemically activated carbonaceous materials obtained from waste tyres and the prepared adsorbent was applied for the adsorptive removal of Cd(II) and Pb(II) in the domestic wastewater samples. The activation efficiency of phosphoric acid (H3PO4) and hydrogen peroxide (H2O2) were evaluated and H2O2 was chosen as the appropriate activati...
