The removal of Diclofenac sodium from waste waters has a high relevance since it belongs to the therapeutic group most commonly found in wastes. An aromatic-free and low-impact technology that efficiently entraps aqueous pollutants is highly desirable. We synthesised two Boc-protected tripeptides (Boc-L-Ala-Aib-L-Val-OH Boc-L-Val-Aib-L-Val-OH) studied their ability form gels with mixtures water...

Cytochrome c can be readily adsorbed onto mesoporous silicates at high loadings of up to 10 mmol g(-)(1) of silicate. The adsorbed protein retains its peroxidative activity, with no diffusional limitations being observed. The protein can be adsorbed onto the external surface of the silicate or, provided that the pore diameter is sufficiently large, into the channels. In aqueous buffer, the cata...

Dendron rod-coil molecules are a novel supramolecular building block, comprising a dendritic unit, a rodlike unit, and a coil unit (J. Am. Chem. Soc. 2001, 123, 4105). It was proposed that in solution these molecules assemble into ribbonlike aggregates of high aspect ratio. We report here on the self-assembly of DRC-molecules in 2-propanol and ethyl acetate as studied with static and dynamic li...

The reactivity of tocopherols with 2,2-diphenyl-1-picrylhydrazyl (DPPH) was studied in model systems in order to establish a method for quantifying vitamin E in plant oils. The method was optimized with respect to solvent composition of the assay medium, which has a large influence on the course of reaction of tocopherols with DPPH. The rate of reaction of α-tocopherol with DPPH is higher than ...

Two laboratory-scale expanded granular sludge bed (EGSB) reactors were operated at 18 and 25 °C, respectively, for the treatment of synthetic wastewater composed of ethanol and 1-methoxy-2-propanol (M2P) in a mass ratio of 4:1. Reactors were operated first with continuous wastewater supply and after with discontinuous substrate supply (5 days a week, 16 h a day) to simulate shift working condit...

Enantioseparation is largely based on the formation of transitional complexes, the solvation species, the stationary phase configurations or the diastereomeric complexes formed by analytes and the chiral stationary phase. Temperature and the chemical nature and composition of the eluent play significant roles during that process. In this study; unique temperature-induced behaviors were observed...
