Abstract Polyphenols are a class of organic contaminants highly present in wastewater from industrial and agro-industrial processes. Adsorptive processes employed to remove effluents without the generation by-products. Among challenges removal is search for adsorbents that have affinity favor interaction with contaminant. In this sense, paper aimed evaluate layered double hydroxide modified sod...

Interaction chromatography has been employed to validate that adsorption of poly[styrene-co-(4-bromostyrene)] (PBr(x) S) random copolymers, where x denotes the mole fraction of 4-bromostyrene (4-BrS) in PBr(x) S in solution depends on the average number of adsorptive segments, the type of adsorbing substrate, and on the co-monomer sequence distribution in PBr(x) S.

Here we document the reduction in porosity observed MOFs upon their glass formation, propose routes to improve this porosity, and speculate on prospective future adsorptive applications.

A recent meta-analysis published in Critical Care proposed presepsin as a novel valuable biomarker for discriminating systemic inflammation from true sepsis [1]. Unfortunately, this excellent paper did not provide information about the occurrence and eventual treatment of acute kidney injury (AKI) in the studied population. The kidney is one of the most frequently afflicted organs during sepsis...

The effect of anharmonicity on the adsorption of CO molecules on the Ni(111) surface has been investigated. The DFT calculations are used to obtain the effective adsorption potential of the CO molecule on the Ni(111) surface. First, using an appropriate slab model, the geometry of adsorption system corresponding to hcp, fcc, bridge, and on-top sites with p(2 x 2) arrangement and coverage of 0.2...

The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two s...

objective(s) in this study, a kind of ph sensitive composite membrane was prepared and drug permeation through it was investigated in terms of ph. rationale of this study originated from the fact that a ph change which may be a result of a disease state in the body can trigger drug release. materials and methods  here, a kind of ph sensitive composite membrane containing different nanoparticle ...

Hemodialysis (HD) is a life-sustaining treatment of crucial importance in managing end-stage renal disease (ESRD). However, this membrane-based therapy associated with acute side-effects due to bioincompatibility issues and limitations on the removal uremic toxins. The present study assessed influence hydrodynamic conditions applied during HD protein-mediated inflammatory thrombotic responses. ...

This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....
