This study focuses on the removal of phenol from aqueous media using Agouraï clay (Fes-Meknes-Morocco region) and Geulmima (Draa Tafilalet region). The characterization by Fourier Transform Infrared (FTIR) Spectroscopy, X-ray diffraction (XRD), N2 adsorption (BET), Scanning Electron Microscopy (SEM), Thermogravimetric differential thermal analysis (DTA/GTA) indicates that it is mainly composed ...

this paper presents density functional theory and non-equilibrium green’s function based first principles calculations to explore the sensing property of adenine and thymine based hetero-junction chins for ammonia and phosphine gas molecules. this modeling and simulation technique plays an important and crucial role in the fast growing semiconductor based nanotechnology field. the hetero-juncti...

This paper investigates the surface film adsorption and lubricity of two different types of potential environmentally friendly cold metal forming lubricants: soybean vegetable oil in water VO/W emulsions and triblock copolymer aqueous solutions. The lubricants have different visual appearance, surface film adsorption characteristic, lubricity and surface cleaning behaviour. The effects of conce...

of past research 1) The individual and competitive adsorption of metal ions on graphene oxides (GOs) studies by experimental and DFT calculation The heavy metal ions can be accumulated in living tissues, so they must be removed from polluted water. Graphene oxides (GOs) are considered as the ideal adsorbent material because the large quantities of oxygen-containing functional groups strengthen ...

A series of highly porous polymers with similar BET surface areas of higher than 1000 m(2) g(-1) but tunable pore ranging from 0.7 nm to 0.9 nm were synthesized through facile ethynyl trimerization reaction to demonstrate the surface property-hydrogen adsorption relationship.

Conversional hydrotreating catalysts mostly use Ni-promoted MoS2 as active sites. Modifying conventional hydrotreating catalyst surface of MoS2 by selectively introducing carbon atom into catalyst crystal structure can lead to an improved electronic property, increased capability of hydrogen adsorption and dissociation. Such process will effectively increase catalyst hydrogenation activity and ...

In the tomato (Lycopersicon esculentum) plant, the fruit juice was found to be the richest source of agglutinating activity. The lectin responsible could be inhibited by oligomers of N-acetylglucosamine, and this property was exploited to purify the lectin by affinity adsorption on trypsin-treated erythrocytes. The lectin is a glycoprotein that cross-reacts immunologically with the lectin from ...

The hierarchically porous and iron-functionalized zeolite ZSM-5 has been fabricated as a Fenton photocatalyst by a facile post-treatment process, which exhibits an excellent visible-light catalytic property in the adsorption/degradation of organic pollutants under mild reaction conditions.
