the interaction between proteins and membranes has an important role in biological pro-cesses.we have calculated energies of interaction between melittin and dmpc bilayer in differenttemperatures. we have used the charmm software for md simulation under the canonical (n,v, e) ensemble at different temperatures. the computations have shown that water moleculeshave more penetration into the bilay...

Almond green hull, an agriculture solid waste, was chemically treated and used for the adsorption of Co (II) from aqueous solutions. The efficiency of this new adsorbent was studied using batch adsorption technique under different experimental conditions such as sorbent amount, initial metal-ion concentration, contact time, adsorbent particle size, and chemical treatment. Optimum dose of sorben...

The performance of a combined catalyst and sorbent material designed for reforming hydrocarbons was evaluated by reacting methane with steam at different temperatures and pressures in a reactor packed with the material. The combined material was in the form of small spherical pellets comprised of a sorbent core of lime encased in a porous shell made largely of sintered alumina that supported a ...

The measurement of total mercury in flue gas based on an economical aluminum matrix sorbent was developed in this paper. A sorbent trap consisted of three tubes was employed to capture Hg from flue gas. Hg trapped on sorbent was transferred into solution by acid leaching and then detected by CVAAS. Hg adsorbed on sorbent was recovered completely by leaching process. The 87.7% recovery of Hg in ...

Mercury emissions from coal fired power plants are generally measured using one of two methods electronic Continuous Emission Monitoring Systems (Hg CEMS) that most commonly use atomic fluorescence, or sorbent traps. Electronic Hg CEMS are often compared against sorbent traps using EPA’s Method 30B Relative Accuracy Test Audit (RATA). Because sorbent traps include mercury contained in the parti...

In the absorption step of the fluorescent treponemal antibody-absorption (FTA-ABS) test (USPHS, 1969) sorbent is used to circumvrent so-called natural antiTreponema pallidum (Tp) reactivity present in a significant proportion of presumed nonsyphilitic individuals (Hunter, Norins, Falcone, and Stout, 1968). It has been postulated that the natural reactivity may be stimulated by nonpathogenic, sa...

Important phenomena were discovered that oxygen-containing expanded graphite an Oxidized OligoGraphene (OOG) obtained after hydrothermic treatment of modified graphite became to be able to interact as sorbent OOG with glycopeptide antibiotics. Introduction. In this work was studied the sorption properties of carbon material as an example of Oxidized OligoGraphene (OOG) concerning glycopeptide a...

Materials that can capture and store CO2 are important. Though CaO is a cheap sorbent, it is inefficient for practical purposes due to sintering and poor diffusion of CO2 through the surface-CaCO3 layer. We have developed a high performance, sintering-resistant CaO-based sorbent by uniformly nanofabricating the CaO nanocrystals on SiO2 microtubes made by organogel templated polymerization.

in this paper, the development of a new potassium carbonateon alumina support sorbent prepared byimpregnating k2co3 with an industrial grade of al2o3 support was investigated. the co2 capturecapacity was measured using real flue gas with 8% co2 and 12% h2o in a fixed-bed reactor at atemperature of 65 °c using breakthrough curves. the developed sorbent showed an adsorptioncapacity of 66.2 mgco2/...

Nowadays nanotechnology as a new direction of science allows us to develop therapeutic methods of the endogenous intoxication syndrome and to create a new class of biocompatible sorbents. In Ukraine first preparations of medical nanotechnology were produced and patented in 1998. These are IKBB (intracorporeal biocorrector), magnet-controlled sorbent (MCS-B), and Micromage-B. The preparations ar...
