Adsorption of superplasticizer admixtures on alkali-activated slag pastes

Alkali-activatedslag(AAS) binders are obtained by a manufacturing process less energy-intensive than ordinary Portland cement (OPC) and involves lower greenhouse gasses emission. These alkaline cements allow the production of high mechanical strength and d ...

Quantification of biodegradation for o-xylene and naphthalene using first order decay models, Michaelis-Menten kinetics and stable carbon isotopes

At a former wood preservation plant severely contaminated with coal tar oil, in situ bulk attenuation and biodegradation rate constants for several monoaromatic (BTEX) and polyaromatic hydrocarbons (PAH) were determined using (1) classical first order deca ...

Hydrodynamic characterisation of a groundwater - surface water system and evaluation of BTEX, PAHs decay and heavy metals fate

Jordi Batlle-Aguilar

Most contaminated sites related to past industrial activities in Europe are adjacent to rivers and urbanized areas. These sites pose a major problem for water authorities and policy makers in terms of contaminants mobility, natural attenuation (or degradat ...

Accumulation and transoformation of sulfonated aromatic compounds by higher plants - toward the phytotreatment of wastewater from dye and textile industries

Jean-Paul Schwitzguebel, Sylvie Aubert, Stéphanie Braillard

Sulfonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation and thus not eliminated by classical wastewater treatments. In the development of a phytoremediation process to remove sulfonated aromatic compound ...

Comparison of naphthalene bioavailability determined by whole-cell biosensing and availability determined by extraction with Tenax

Jan Roelof van der Meer, Stefanie Kohlmeier, Robin Tecon

A rapid biological method for the determination of the bioavailability of naphthalene was developed and its value as an alternative to extraction-based chemical approaches demonstrated. Genetically engineered whole-cell biosensors are used to determine bio ...

Photooxidation of naphthalenesulfonic acids: Comparison between processes based on O-3, O-3/activated carbon and UV/H2O2

Urs von Gunten, Silvio Canonica

The aim of the present study was to analyze and compare the efficacy of UV photodegradation with that of different advanced oxidation processes (03, UV/H2O2, O-3/activated carbon) in the degradation of naphthalenesulfonic acids from aqueous solution and to ...

Excited-State Dynamics of Donor−Acceptor Bridged Systems Containing a Boron−Dipyrromethene Chromophore: Interplay between Charge Separation and Reorientational Motion

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...

Nongenomic actions of bile acids. Synthesis and preliminary characterization of 23- and 6,23-alkyl-substituted bile acid derivatives as selective modulators for the G-protein coupled receptor TGR5

Johan Auwerx, Kristina Schoonjans

23-Alkyl-substituted and 6,23-alkyl-disubstituted derivatives of chenodeoxycholic acid are identified as potent and selective agonists of TGR5, a G-protein coupled receptor for bile acids (BAs). In particular, we show that methylation at the C-23(S) positi ...

A comparative study of VOCs in Singapore and European office buildings

Claude-Alain Roulet

This study compares the characteristics of volatile organic compounds (VOCs) and the associated factors affecting them within European (EU) and Singapore buildings. Generally, concentrations of target VOCs determined in the two types of buildings were with ...

Endeavors in synthetically oriented organometallic chemistry

Giuseppe Mangano

This thesis work aimed to show the potentialities of the organometallic approach and, in particular, the organoalkali one, in Organic Synthesis (whose possibilities cannot be underestimated). A wide opening on the big landscape of possibilities has been re ...
