Modelling the fate of oxidisable organic contaminants in groundwater

Subsurface contamination by organic chemicals is a pervasive environmental problem, susceptible to remediation by natural or enhanced attenuation approaches or more highly engineered methods such as pump-and-treat, amongst others. Such remediation approach ...

Enthalpic, entropic, and square gradient contributions to the surface energetics of amine-cured epoxy systems

The evolution of surface tension during polymerization of three amine-cured epoxy systems was investigated. Due to the chemical reaction of the epoxy groups with primary and secondary amines, the energetic status of an epoxyamine system increased during p ...

A one-dimensional reactive multi-component transport model for biodegradation of petroleum hydrocarbons in groundwater

David Andrew Barry

A one-dimensional (1-D) multi-component model accounting for hydrological transport inorganic equilibrium chemistry and microbial activity during kinetically controlled biodegradation in groundwater of compounds such as benzene, toluene, ethylbenzene and x ...

[OH(X)] measurements by resonant absorption spectroscopy in a high pulse voltage triggered Dielectric Barrier Discharge

Cyrille Hibert

Good understanding of the different phases of involved plasma-chemistry is essential for the development of non thermal plasma technologies for pollution control. These techniques are often based on the production of radicals from dissociation parent gases ...

Bis- and oligo(trifluoromethyl)benzenes: hydrogen/metal exchange rates and gas-phase acidities

The proton mobilities (kinetic acidities) of bis- and tris(trifluoromethyl)benzene are dictated to a large extent by steric factors; the trifluoromethyl group is a fairly bulky substituent that can seriously impede the approach of the metalating reagent. M ...

Ability of 16 priority PAHs to be directly cytotoxic to a cell line from the rainbow trout gill

Kristin Schirmer

Sixteen polycyclic aromatic hydrocarbons (PAHs) were screened for their ability to be directly cytotoxic to a cell line from the rainbow trout gill, RTgill-W1. Exposure times of 2 h or less were sufficient for direct cytotoxicity to be detected, which appe ...

Isolation and structural characterisation of rhamnogalacturonan oligomers generated by controlled acid hydrolysis of sugar-beet pulp

Controlled acid hydrolysis was applied to a deesterified beet pulp and the resulting soluble fraction was fractionated on a Biorad AG 1X8 column eluted by ammonium acetate pH 6 from 0.05 to 2 M. Eight retained fractions were obtained, containing almost exc ...

POLYETHYLENE-GLYCOL BOUND BENZYL-DERIVATIVES AND FLUORENYL-DERIVATIVES AS SOLUBILIZING SIDE-CHAIN PROTECTING GROUPS IN PEPTIDE-SYNTHESIS

The covalent attachment of polyethylene glycol (PEG) to commonly used protecting groups and their use in peptide synthesis was examined. PEG bound to fluorenyl- and benzyl- type side chain protection for Lys and Glu results in increased solubility of hydro ...

Absorption

Urs von Stockar

A review is given of gas absorption which is generally used for the gas with the liq. Gas solubilities and mass transfer concepts used in the design of absorption columns (e.g. Kremser-Brown method), film factor concept, penetration theory, and Chilton-Col ...

Catalyst Support and Solvent Effects during Lignin Depolymerization and Hydrodeoxygenation

Jeremy Luterbacher, Florent Emmanuel Héroguel

We studied and compared the hydrodeoxygenation (HDO) and depolymerization of aldehyde-stabilized lignin and 4-propylguaiacol (PG), a model lignin monomer. We demonstrated by liquid phase adsorption that PG HDO catalyzed by Ru/C can be achieved in isooctane ...
