Aqueous Fabrication of pH-Gated, Polymer-Brush-Modified Alumina Hybrid Membranes

In this Article, we studied the surface immobilization of five organic-acid-modified atom-transfer radical polymerization (ATRP) initiators based on salicylic acid, catechol, phthalic acid, and m- and p-benzoic add on alumina, and we also investigated the ...

ZrNO-Ag co-sputtered surfaces leading to E. coli inactivation under actinic light: Evidence for the oligodynamic effect

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Mirela Pascu

This study reports visible light sensitive ZrNO and ZrNO-Ag polyester samples prepared by sputtering in an Ar/N-2/O-2 atmosphere leading to Escherichia coil bacterial inactivation. The bacterial inactivation by ZrNO avoids the increasing environmental conc ...

Dinuclear Gd(III) Polyaminocarboxylates as Building Blocks for MRI Contrast Agents

Bibimaryam Mousavi

Magnetic resonance imaging (MRI) technique is at the forefront of biomedical and clinical imaging. Its superb spatial resolution, noninvasive nature and use of benign radiation outweigh its intrinsic low detection sensitivity. However paramagnetic relaxers ...

Determination of trace metals accumulated and internalized by marine phytoplankton; interferences with colloidal organic matter

In the present work, we study the effects that aggregation of humic acids in seawater, and its adsorption to surfaces, can have on the determination of Cu and Pb accumulation by phytoplankton within the context of metal bioavailability studies, using the d ...

Structural modifications of ionic liquid surfactants for improving the water dispersibility of carbon nanotubes: an experimental and theoretical study

Davide Demurtas

The 1-hexadecyl-3-vinylimidazolium bromide (hvimBr), a water-soluble long-chain imidazolium ionic liquid (IL) with surfactant properties, showed the ability to produce stable homogeneous aqueous dispersions of pristine Single-Walled Carbon Nanotubes (SWNTs ...

Chemical-mechanical polishing of tungsten

Jelena Stojadinovic

The chemical-mechanical polishing process (CMP) is an essential part of the production of integrated circuits. Metal to be polished in the CMP reacts with the oxidants from the aqueous suspension (slurry) and the passive film is formed on the metal surface ...

Electrospray ionization mass spectrometry

Michel Prudent

Metal ions are essential elements in all living systems. Their detections and identifications in biological processes require different methodologies. Mass spectrometry is one of the commonly used techniques in bioinorganic analyses to fulfill these requir ...

Silyl methallylsulfinates: efficient and powerful agents for the chemoselective silylation of alcohols, polyols, phenols and carboxylic acids

Pierre Vogel, Loay Awad, Cotinica Craita, Xiaogen Huang

Alcohols, phenols and carboxylic acids are silylated with very good yields in the presence of silyl methallylsulfinates under non- basic conditions and with the formation of volatile co-products. ...

Liquid-core capsules as a tool in biotransformations

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...
