More than 50 yr. after the proposal of the Dewar-Chatt-Duncanson model for the binding of olefins to transition-metal atoms, the first structurally characterized example of a silver-C2H4 complex [Ag(h2-C2H4)3]+ was obtained with the help of the very weakly ...
Recent advances in the fields of biotechnology and medicine have intensified the necessity for pharmaceutical-grade biomacromolecules purification (e.g. enzymes, antibodies, plasmid DNA). One of the key factors for a successful downstream process is the po ...
A description of ion transport through geometrically defined nanoslits is presented. It is characterized by the effective surface charge density and was obtained by impedance spectroscopy measurements of electrolytes with different physico-chemical propert ...
Chromatography is increasingly being used for large-scale preparative separation of precious biological components such as recombinant proteins and DNA. Several kinds of mathematical models are used to describe the liquid chromatography process. The aim of ...
The Off-Gel™ technology is an isoelectric focusing (IEF) fractionation method which enables the purification of one or several proteins in a solution placed on an immobilised pH gradient (IPG) gel. The present thesis is devoted to its characterisation and ...
A model showing the importance of the parameters characterizing ion transport through geometrically defined nanoslits filled with electrolyte is presented. A conductance plateau sin log-log scaled at low salt concentrations in the nanometer-sized apertures ...
Pollution can undergo long-range transport and impact the tropospheric chemistry thousands of kilometers downwind from the source region. Recently, there is interest in the intercontinental transport (ICT) of pollution between the main industrial regions o ...
Novel chemical compounds of the general formula KA, in which K is a 5- or 6- membered heterocyclic ring having 1-3 hetereo atoms, which can be independently N, S, or 0 with the proviso that at least one of the hetereo atoms must be a quaternized n ...
Diaqua (15-crown-5) copper (II) dinitrate is an organic salt presenting an one-dimensional commensurate modulation. The diffraction pattern is characterized by strong Bragg reflections and weaker superstructure reflections (satellites). The structure is de ...
Two main factors govern the ingress of chloride ions into concrete reinforced with ordinary steel reinforcement, from de-icing salts: (1) the cover concrete (permeability, thickness), and (2) the microclimatic conditions (humidity, temperature, concentrati ...
