Mechanical Reinforcement of Hydrogels through Physical Crosslinks and Double Network Granular Architecture

Throughout nature, organisms fabricate a myriad of materials to sustain their lifestyle. Many of the soft materials are composed of water-swollen networks of organic molecules, so-called hydrogels. They generally contribute to the mechanical integrity of t ...

D35-TiO2 nano-crystalline film as a high performance visible-light photocatalyst towards the degradation of bis-phenol A

Ulf Anders Hagfeldt, Lin Yang, Xue Bai

Dye-sensitized photocatalytic suspension system for wastewater treatment is still limited in practice due to particle aggregation, fast charge carrier recombination, poor stability and recycling issue. In this study, we combine TiO2 nano-crystalline film w ...

En route to CO2-containing renewable materials: catalytic synthesis of polycarbonates and non-isocyanate polyhydroxyurethanes derived from cyclic carbonates

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden

Combining CO2-chemistry with biomass conversion allows renewable polymeric materials including polycarbonates and polyhydroxyurethanes (PHUs) to be generated. The demand for robust materials with modular properties that can be prepared on an industrial sca ...

Elevated Concentrations of 4-Bromobiphenyl and 1,3,5-Tribromobenzene Found in Deep Water of Lake Geneva Based on GCxGC-ENCI-TOFMS and GCxGC-mu ECD

Jeremy Samuel Arey, Saer Samanipour, Petros Dimitriou Christidis, Deedar Nabi

We quantified the concentrations of two little-studied brominated pollutants, 1,3,5-tribromobenzene (TBB) and 4-bromobiphenyl (4BBP), in the deep water column and sediments of Lake Geneva. We found aqueous concentrations of 625 +/- 68 pg L-1 for TBB and 66 ...

VUV/UV light inducing accelerated phenol degradation with a low electric input

Juan Kiwi, Mengkai Li

This study presents the first evidence for the accelerated degradation of phenol by Fenton's reagent in a minifluidic VUV/UV photoreaction system (MVPS). A low-pressure mercury lamp used in the MVPS led to a complete degradation of phenol within 4-6 min. T ...

In situ coupling of Ti2O with rutile TiO2 as a core-shell structure and its photocatalysis performance

Lijie Wang, Peng Zhang

The fabrication of high-performance, low-cost photocatalysis materials, which absorb in the visible-light region, is of significance for their practical applications. A Ti2O@TiO2 (rutile) core-shell structure was fabricated through dehydrogenation and oxid ...

Curing kinetics and thermomechanical properties of latent epoxy/carbon fiber composites

Véronique Michaud, Pierre-Etienne Bourban, Sara Dalle Vacche

In this work, resins based on diglycidyl ether of bisphenol A (DGEBA) epoxy and a latent hardener, dicyandiamide (DICY), as well as carbon fiber (CF) composites based on them, were prepared with three commercial accelerators: a methylene bis (phenyl dimeth ...

Does Cancer Start in the Womb? Altered Mammary Gland Development and Predisposition to Breast Cancer due to in Utero Exposure to Endocrine Disruptors

Cathrin Brisken

We are now witnessing a resurgence of theories of development and carcinogenesis in which the environment is again being accepted as a major player in phenotype determination. Perturbations in the fetal environment predispose an individual to disease that ...

Developmental and metabolic brain alterations in rats exposed to bisphenol A during gestation and lactation

Rolf Gruetter, Nicolas Kunz

In recent years, considerable research has focused on the biological effect of endocrine-disrupting chemicals. Bisphenol A (BPA) has been implicated as an endocrine-disrupting chemical (EDC) due to its ability to mimic the action of endogenous estrogenic h ...

An innovative ultrasound, Fe2+ and TiO2 photoassisted process for bisphenol a mineralization

César Pulgarin, Jessica Ivana Nieto Juarez

This paper explores the degradation of a model pollutant, bisphenol A, by an advanced oxidation process that combines sonolysis, Fe2+, and TiO2 in a photoassisted process. Experiments were done under saturated oxygen conditions. The effect of different Fe2 ...

Anodic oxidation of phenol on Ti/IrO2 electrode: Experimental studies

Stéphane Fierro

The electrochemical oxidation of acidic solutions of phenol on a Ti/IrO2 anode has been investigated by cyclic voltammetry and bulk electrolysis in a single-compartment cell. In the potential region of oxygen evolution, anodic oxidation resulted in electro ...

Dynamic capillary effects in liquid composite moulding with non-crimp fabrics

Véronique Michaud

A technique is presented to measure the capillary pressure drop DPg during infiltration of non-crimp fabrics by a liquid matrix. Three types of liquids are used: polyethylene glycol (PEG) dissolved in water, a thermoset epoxy resin and a reactive thermopla ...

Polysulfones as new organic catalysts : mechanism and development of new strategies for polyol selective semi-protection

Dean Markovic

Even unsubstituted butadiene adds to sulfur dioxide in the hetero-Diels-Alder mode more rapidly than in the chelotropic mode. The sultine can be observed in equilibrium with the diene and the sulfur dioxide only at low temperature and in the presence of CF ...
