In order to rationally design a bio-functional surface based on the adsorption of a His-tag antigen, three requirements have to be considered: the bio-recognition element, the driving forces for the adsorption process an...

The adsorption of magnesium hydride (MgH2) is studied by Density Functional Theory (DFT) on (8,0) and (8,8) single-walled carbon nanotubes (SWCNT) containing a vacancy. In the case of (8,0), the adsorption geometry is a ...

Abstract Owing to the widespread usage of synthetic dyes, water contamination prompted by these materials has led to a severe menace on aquatic ecosystem and also on living organisms health. Chitosan modified with cyanog...

In this work, the adsorption of arsenic (V) onto crystalline substituted goethites was studied for samples with different Sn- contents. The highest Sn-content of the prepared samples was 5.5 (expressed as 100?[Sn]/[Sn]+[...

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, a...

This work is included the synthesizs of two azo dyes from the reaction of p-methoxy aniline and 2-amino benzo thiazol .via diazounium ions.A number of clays are tested as adsorbents for the removal of these dyes from the...

Experimental adsorption isotherms of bovine serum albumin (BSA) adsorbed on sulfonated microspheres were described by means of two analytical models: the first is the well-known Langmuir–Freundlich model (LF), and the ...

In the present paper, finite multilayer adsorption is described as a fractional statistics problem, based on Haldane's statistics. In this scheme, the Helmholtz free energy and its derivatives are written in terms of a p...

The adsorption of arsenate onto a Mg/Al/Fe layered double hydroxide (Fe-LDH) was studied at different anion concentration, pH, temperature and stirring rate. Different characterization techniques such as FT-IR, X-ray dif...

Corrosion products formation on carbon steel in oil and gas environments can induce galvanic corrosion and hinders corrosion inhibitor (CI) adsorption due to surface heterogeneities (i.e., roughness, competitive adsorpti...

The research including used anew adsorbent substance collected from sandstorms  which arrived to Mosul city to study adsorption of Benzoic acid and some substituted and application of kinetics Models (pseudo first and s...

The research is included studying the kinetic of the adsorption of two azo dyes synthesized in our laboratories on a local bentonite  thermally activated .The efficiency and capacity of adsorption are calculated at the ...

Abstract The study involves preparation of magnetic activated carbon by treatment of the carbon with(0.25M) Fe2(SO4)3.5H2O Carbon prepared was used for the removal of methylene blue dyes from aqueous solution. The study ...

The adsorption kinetics of phosphate on goethite has been studied by batch adsorption experiments and by in situ ATR-IR spectroscopy at different pH, initial phosphate concentrations and stirring rates. Batch adsorption ...

Multi-walled carbon nanotubes (CNTs), pristine and subjected to treatments, are comparatively characterized from N2 and Kr (77 K) adsorption measurements. The CNTs are lab-synthesized by in situ chemical vapour depositio...

Metal-organic framework (MOF) nanomaterials are emerging porous coordinative polymers with large surface area and high porosity. Their application scenarios highly depend on adsorption/desorption dynamics of guest molecu...

Bio-cover is a novel MSW landfill cover. Compared to the conventional compacted clay cover, it exhibits a higher methane oxidization capacity to mitigate methane emissions from landfill. Use of biochar in the bio-cover c...

In this study, hydrogels of polyacrylic acid (PAA) were synthesised using free radical polymerization of acrylic acid. This process was carried out in an aqueous medium in the existence of ammonium persulfate (APS) actin...

In this research used the electrical conductivity, potential difference, acidity function and the probability Sticking on surface were used to detected the mechanism of Ions transportation of citric acids by adsorption f...

In the present work, a generalized lattice-gas model to study multilayer adsorption of interacting polyatomic species on heterogeneous surfaces is introduced. Using an approximation in the spirit of the well-known Brunau...

A new approach model was developed for the pore size characterization of carbon porous materials, using adsorption gases. The experimental adsorption isotherms of CO2 and N2 onto carbon nanoparticles were used to test th...

Random sequential adsorption of k -mers of different sizes and shapes deposited on two types of fractal surfaces (deterministic and statistical) is studied. These kinds of substrates present intrinsic heterogeneities....

It was aimed to evaluate a variety of conventional and emerging CO2-selective adsorbents, considering their use in a five-step VSA (Vacuum Swing Adsorption) system for flue gas capture. In most works, porous materials sy...

A crude extract rich in plant cysteine peptidases was obtained from the latex of the fruits of Araujia hortorum, a South American climbing plant. The highly concentrated extract was immobilized onto titanium dioxide to p...
