Quality control of silane mixtures with low-field NMR spectroscopy
Simon Kern, Clemens Minnich, S-PACT
In recent years, functional trialkoxy silanes have proven their versatility. After hydrolysis with water or alcohols, modified silanes are applied in numerous applications: from weather protection of buildings to bonding-imparting properties in the glass fiber industry, for sealants and adhesives...

Drug metabolization in plants - Method development for detection of environmentally relevant trace levels
Lisa Emhofer, Institute of Analytical Chemistry, Johannes Kepler University
Due to steady population growth, increasing chronic illnesses and advances in medical science, the consumption of drugs increases continuously. For example, in Germany an increase of 40 - 65% of current demand is expected by 2045. As a negative effect, more and more drug residues are being in...

Optimization of bacterial culture and plasmid purification
Sandrine Hamels, Blandine Vanbellinghan, Eppendorf Application Technologies S.A.
Rafal Grzeskowiak, Eppendorf AG

Plasmid purification from bacterial culture is a commonly performed protocol in molecular biology and life science laboratories. For medium scale preparations, 15 mL conical tubes with screw caps are typically used which often pose handling drawbacks and don't enable achieving optimal productivit...

Foam stability and foam structure under high pressure for tertiary oil production - Foam analysis under pressure up to 35 MPa
Svenja Sergelius, Arne Kordts, Krüss GmbH
Martina Szabries, TU Bergakademie Freiberg

Foam properties such as stability, structure, foamability and bubble size distribution depend, among other things, on the type and phase behavior and concentration of the stabilizing surfactant, on the salt content as well as on additives such as polymers and finally on the temperature. When ...
