Polyelectrolyte multilayers (PEMs) based on biopolyelectrolytes are highly appealing for the surface engineering of biomaterials and the tuning of cell response and phenotypes for biomedical applications. However, cell a...

Changes of bentonite surface structure under the influence of direct microwave irradiation during adsorpion of Cu2+ from concentrated solutions were investigated by X-ray and EDS analysis. The microwave treated bentonite...

In this work we demonstrate the feasibility to couple adsorption with Fenton and photo-Fenton process to separate and mineralize crystal violet (CV) dissolved in water. Montmorillonite (MMT) and Iron modified Montmorill...

Abstract In this study, an environmentally friendly nanocomposite was synthesized and comprehensively characterized for its potential to adsorb Pb2+ ions and malachite green dye (MG) from aqueous solutions. The composite...

The adsorption of Sr(II) cations by Boron-doped TiO2 was investigated.  The adsorbent samples were obtained by liquid-phase sol-gel method using the aqua complex precursor [Ті(ОН2)6]3+‧3Cl- and modifying reagent h...

Abstract This study explored the adsorption of methylene blue (MB) from aqueous solutions using natural clay as an adsorbent. The effects of contact time, initial dye concentration, adsorbent dosage, and pH were systemat...

This paper presents a study of adsorption and vibrational features of folic acid, using surface-enhanced Raman scattering (SERS). A gold-capped silicon nanopillar (Au NP) with a height of 600 nm and a width of 120 nm was...

Carbonyl sulfide (COS) is a dangerous gas produced from fossil fuel combustion and petrochemical procedures, so proper adsorbent and sensors are required for removal and detection. In this work, we study by Density Funct...

The adsorption of picloram on Fe Oxide Pillared Clays (PILC) as a possible basis for the development of adsorbent materials for the remediation of polluted environments was studied. To this end, after characterizing PILC...

Aims: (i) To determine the aflatoxin B1 (AFB1) adsorption and desorption dynamics in the presence of Lactobacillus rhamnosus RC007 under simulated transit of AFB1 at each gastrointestinal tract (GIT—saliva, stomach and...

In this work granular activated carbon has been chosen as an absorbent in order to investigate theCr(VI) reduced by adsorption experiments. Several batch chromium-sorption experiments were carried out using 0.25 gof gran...

The effects of histidine and its imidazole ring adsorption on the electronic transport properties of graphene were investigated by first-principles calculations within a combination of density functional theory and non-e...

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...

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]+[...

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 ...

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...

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...

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...
