Nanoparticles made of FePt alloy in a face-centered-tetragonal (fct) structure have agreat interest for the enhancement of data density (> 1 Tbit/in²) in magnetic...

The aim of this work consists in the recycling of the styrenic polymers coming from waste of electric and electronic equipments. Polystyrene (PS), high impact...

Illicit drugs are metabolized or eliminated unchanged in the urine and/or feces then join the sewer system. The quantification of these products in wastewater disposal...

In natural water, humic substances are a source of reactive species production, in the presence of light and oxygen, such as singlet oxygen, superoxide, hydroxyl...

The aim of this work is to understand the influence of silica nanoparticles on the physical transitions of different polymer matrix : polyfurfuryl alcohol (PFA),...

Several ligands derived from D-glucosamine, designed for different catalytic reactions havebeen synthesized. The ligands for homogeneous catalysis based on...

MOFs are generated from the association of metallic clusters connected by organic linkers toform crystalline porous materials. Their discovery was a breakthrough in...

The direct functionalization of C-H bonds constitutes a faster and more « atom-economical »synthetic approach. This concept is gradually modifying organic chemistry,...

In this work, we investigated both the use of CO2 supercritical drying conditions and the use of biopolymer to modify the growth and aggregation of inorganic Layered...

Organic and inorganic semi-volatile compounds, are found in the different compartments of the environment. While most of these pollutants are of anthropogenic origin,...

The objective of the present work is the analysis of coextrusion processes by numerical simulation based on phase-field modeling of stratified confined flows. The...
