Mechanochemistry offers a unique opportunity to modify and manipulate crystal forms, often providing new products as compared with conventional solution methods. While promising, there is little known about how control the solid form through mechanochemical means, demanding dedicated investigations. Using model organic cocrystal system (isonicotinamide:glutaric acid), we here demonstrate that mechanochemistry, polymorphism can be induced in molecular solids under conditions seemingly...
Cardiac vascular diseases, especially acute myocardial infarction (AMI), are one of the leading causes death worldwide. Therefore cardio-specific biomarkers such as cardiac troponin I (cTnI) play an essential role in field diagnostics. In order to enable rapid and accurate measurement cTnI with potential online measurements, a chemiluminescence-based immunosensor is presented proof concept. A flow cell was designed combined sensitive CMOS camera allowing optical readout. addition,...
One of the challenges high-temperature polymer electrolyte membrane fuel cells is poisoning Pt catalyst with H3PO4. H3PO4 imbibed into routinely used polybenzimidazole-based membranes, which facilitate proton conductivity in temperature range 120–200 °C. However, when leached out by water produced during operation, adsorbs on surface, blocking active sites and hindering oxygen reduction reaction (ORR). The to H3PO3, occurs at anode due a combination low potential presence gaseous H2, has...
The Simons process is an electrochemical fluorination method to prepare organofluorine compounds. Despite the wide application, underlying mechanism still unclear. We report investigation of black film formed on surface anodes in aHF by situ Ni K-edge X-ray absorption near edge structure (XANES) investigation. An cell for spectroscopy (XAS) presented.
In this work (Part II) the application of new polystyrene based microcarriers in cell culture technology is demonstrated. Carriers with a variety surface modifications were tested as growth support for line BHK 21. The behavior cells and to attachment compared Cytodex 3 (Pharmacia), which was used reference carrier. To select carriers supporting surfaces, broad screening petri dish experiments carried out. Candidates highest rates investigated spinner flask further detail. Polystyrene...
Abstract In this work (Part I), surface modified styrene polymers as new microcarrier material for animal cell culture were extensively investigated. The first synthesis steps-carried out by chloromethylation, sulphonation and nitration of the polystyrene matrix-resulted in precursors with a defined layer thickness. obtained hydrophobic bulk phase showed limited absorption hydrophilic media components compared to polysaccharides matrices like dextran. By varying reaction conditions and/or...
