Toward Understanding the Chloroquine Action at the Molecular Level in Antimalarial Therapy - X-ray Absorption Studies in Acetic Add Solution

The local atomic structure around the central iron of the synthetic soluble analog of malarial pigment in acetic acid solution and with addition of chloroquine as found by X-ray absorption spectroscopy is reported. The special interest was drawn to the axi ...

On the photocatalytic degradation of phenol and dichloroacetate by BiVO4: The need of a sacrificial electron acceptor

César Pulgarin, Laura Ding, Nikola Castillo, Andre Heel

The photodegradation of phenol and dichloroacetic acid (DCAA) by \ce{BiVO4} was studied in the absence as well as presence of selected electron scavengers. The experiments were performed under the visible (vis) irradiation of aqueous solutions over a wide ...

A post-modification approach to peptide foldamers

Harm-Anton Klok, Laure Menin, Nadja Franz

Hydrophilic/hydrophobic patterning is a powerful strategy to control folding in non-natural polymers/oligomers. In this contribution, we present a novel strategy for the preparation of alternating hydrophilic/hydrophobic patterned non-natural peptide folda ...

Synthesis of sequence-defined oligomers and polymers

Nadja Franz

The preparation of synthetic polymers with exact control over chain length and monomer sequence is one of the long-standing challenges in polymer science. Nature perfectly masters the synthesis of high molecular weight, perfectly monodisperse polypeptides ...

pH prediction and control in bioprocesses using mid-infrared spectroscopy

Ian William Marison, Jonas Schenk

An on-line pH monitoring method based on mid-infrared spectroscopy relevant to bioprocesses is presented. This approach is non-invasive and does not require the addition of indicators or dyes, since it relies on the analysis of species of common buffers us ...

Uncertainties and error propagation in kinetic hard-modelling of spectroscopic data

Julien Léo Billeter, Konrad Hungerbühler

A novel method is presented for the rigorous propagation of uncertainties in initial concentrations and in dosing rates into the errors in the rate constants fitted by multivariate kinetic hard-modelling of spectroscopic data using the Newton–Gauss–Levenbe ...

Electrochemical investigations in low conductivity organic solvents using microelectrodes

Alain Fankhauser

Electrochemical acetoxylation has been widely investigated about 40 years ago. However, there are only a limited number of studies in non-aqueous electrolytes, mainly because of difficulties related with the extremely low electrical conductivity of organic ...

Electrochemical destruction of chlorophenoxy herbicides by anodic oxidation and electro-Fenton using a boron-doped diamond electrode

Christos Comninellis

The degrdn. of herbicides 4-chlorophenoxyacetic acid (4-CPA), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in aq. medium of pH 3.0 was comparatively studied by anodic oxi ...

Electrochemical decontamination of waters by advanced oxidation processes (AOPS): Case of the mineralization of 2,4,5-T on BDD electrode

Christos Comninellis, Pierre-Alain Michaud

In the present work, herbicide 2,4,5-trichlorophenoxyacetic acid, more commonly known as 2,4,5-T herbicide, has been completely mineralized (i.e. transformed into CO2 and H2O) in satd. aq. solns. using a semi-industrial electrochem. cell that contains a bo ...

Separation of binary mixtures by thermostatic sweeping gas membrane distillation II. Experimental results with aqueous formic acid solutions

Urs von Stockar, Ian William Marison

Aq. solns. of formic acid were exptl. investigated in a modified sweeping gas membrane distn. (SGMD) configuration. A thermostated sweeping gas was used in order to enhance the mass transfer performance. A new tubular module was designed and built for this ...
