A composite zeolite adsorbent was prepared by conformally depositing an ultrathin porous TiO2 coating on the external surface of the 5A zeolite by molecular layer deposition (MLD) and subsequent calcination. The composite adsorbent showed significantly improved ideal adsorption selectivity for CO2-CH4, CO2-N2 and propylene-propane.

The removal kinetics and mechanism of alizarin red-s dye, adsorptions on coconut shell activated carbon [CSAC] is studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing the dye from aqueous solution. The adsorption removal of Alizarin Red-S dye on CSAC was investigated using batch adsorption technique. The di...

Versatile odor sensors that can discriminate among huge numbers of environmental odorants are desired in many fields, including robotics, environmental monitoring, and food production. However, odor sensors comparable to an animal's nose have not yet been developed. An animal's olfactory system recognizes odor clusters with specific molecular properties and uses this combinatorial information i...

The ability of activated carbon produced from coconut shell to remoe mercury Hg (II), Lead Pb (II) and Copper Cu (II) from dye effluent was investigated. The activated carbon was produced through chemical activation processes by using zinc chloride (ZnCl2). The adsorption capacity was determined as a function of adsorbent dosage. The adsorption Isotherms of the studied metals on adsorbent were ...

BACKGROUND Removal of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg(+2)) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its app...

cystic hydatid disease is caused by cystic larval (metacestode) stages of echinococcus granulosus. this parasite can potentially occur all over the world especially in mediterranean and middle east countries and some parts of africa, latin america and china which have major foci of human infections. the cyst wall of metacestodes consists of inner, middle and external layers. to date, little att...

A multi-functional polystyrene based adsorbent (NKU-9) with a unique mesoporous and a high surface area was prepared by suspension polymerization for removal of therapeutic toxins in blood purification. The adsorbent produced had an almost equal amount of mesopore distribution in the range from 2 to 50 nm. The adsorption of serum toxins with different molecular weights were examined by in vitro...

In this paper, a detailed 3D modelling of flow and coupled heat and mass transport in a channel coated with adsorbing material is presented. A comparative study between a simplified 1D model and the detailed 3D model is carried out. Both 3D and 1D predictions are compared with experimental data available from literature as well. The time-dependent variation of temperature and heat flux distribu...

This paper describes work on alternative technologies associated with an urban maglev system that employs Halbach arrays of permanent magnets onboard a moving vehicle to induce levitating currents in a stationary “track”. A laminated structure, composed of stacks of thin conducting sheets, has several advantages over a litz-cable ladder as the track. Modeling and experimental results for the la...

The strain of an optical fiber, embedded in a composite laminated plate, was measured using radio frequency iiiterferometery. While the response of a similar fiber glued to the plate was linear with the applied loading, the strain experienced by the embedded fiber exhibited significant fluctuations around the linear expected trend. This phenomenon is qualitatively described in terms ofpolarizat...
