Diseño de plataformas de estado sólido para la determinación simultánea de cromo III y VI [Design of solid-state platforms for the simultaneous determination of Cr III and VI]

Speciation analyses of an element allow obtaining information on the concentrations of its chemical forms present in specific environments. Chromium is largely distributed in industrial effluents often at acid pH, with the relevant oxidation states Cr (III ...

Amino-functionalized macroporous silica for efficient tryptic digestion in acidic solutions

Hubert Girault, Liang Qiao, Jingjing Wan

Amino-functionalized macroporous silica foam (NH2-MOSF) has been developed as a host reactor to realize highly efficient proteolysis in acidic solutions where normal tryptic reactions cannot occur. The digestion protocol consists simply of adding the funct ...

Metabolic Characterization of a Sirt5 deficient mouse model

Johan Auwerx, Kristina Schoonjans, Norman Lionel Moullan, Lilia Noriega Lopez, Jiujiu Yu

Sirt5, localized in the mitochondria, is a member of sirtuin family of NAD(+)-dependent deacetylases. Sirt5 was shown to deacetylate and activate carbamoyl phosphate synthase 1. Most recently, Sirt5 was reported to be the predominant protein desuccinylase ...

Influence of bicarbonate ions on the deterioration of mortar bars in sulfate solutions

Karen Scrivener, Barbara Lothenbach, Wolfgang Kunther

This work investigates the influence of bicarbonate ions on the deterioration of cementitious material exposed to sulfate ions. Mortars based on a CEM I and on a CEM III/B cement were investigated. Experimental investigations were compared to thermodynamic ...

Deletion of Sirt3 does not affect atherosclerosis but accelerates weight gain and impairs rapid metabolic adaptation in LDL receptor knockout mice: implications for cardiovascular risk factor development

Johan Auwerx, Julien Weber, Yuan Liu, Chad Brokopp

Sirt3 is a mitochondrial NAD(+)-dependent deacetylase that governs mitochondrial metabolism and reactive oxygen species homeostasis. Sirt3 deficiency has been reported to accelerate the development of the metabolic syndrome. However, the role of Sirt3 in a ...

Laccases: Potential treatment for removal of micropollutants in municipal wastewater?

David Andrew Barry, Christof Holliger, Julien Maillard, Jonas Margot

Relatively high concentrations of micropollutants such as pharmaceuticals and biocides in municipal wastewater treatment plants (WWTP) effluents underscore the necessity to develop new treatments. Organisms that produce oxidative enzymes such as laccases a ...

Nonlinear Light Scattering and Spectroscopy of Particles and Droplets in Liquids

Sylvie Roke

Nano -and microparticles have optical, structural, and chemical properties that differ from both their building blocks and the bulk materials themselves. These different physical and chemical properties are induced by the high surface-to-volume ratio. As a ...

Passivation of a CoCrMo PVD Alloy with Biomedical Composition under Simulated Physiological Conditions Studied by EQCM and XPS

Stefano Mischler

Kinetics of passive film growth on a CoCrMo biomedical alloy have been studied using the Electrochemical Quartz Crystal Microbalance technique (EQCM) in phosphate buffer solution at room temperature and 37 degrees C. CoCrMo layers were deposited on the qua ...

Photocatalytic discoloration of aqueous malachite green solutions by UV-illuminated TiO2 nanoparticles under air and nitrogen atmospheres: effects of counter-ions and pH

César Pulgarin, Christophe Roussel

Under air atmosphere, the photocatalytic discoloration of malachite green (MG) aqueous solutions (a triphenylmethane dye) in the presence of TiO2 and UV light followed an oxidative pathway, involving an N-demethylation process evidenced by a blue shifting ...

Dispersion-Corrected Energy Decomposition Analysis for Intermolecular Interactions Based on the BLW and dDXDM Methods

Wei Wu

As the simplest variant of the valence bond (VB) theory, the block-localized wave function (BLW) method defines the intermediate electron-localized state self-consistently at the DFT level and can be used to explore the nature of intermolecular interaction ...
