“…This indicates that the effect of temperature was more marked in thiocyanate oxidation than in cyanide oxidation (see Table 1). Several authors have reported activation energies between 25.8 and 150 kJ/mol for the oxidation of other inorganic compounds [52][53][54]. The activation energy of formate and ammonia formation (Eq.…”

“…There were two reasons for the different recipes: (i) the cathode gel mixture had a lower surface tension due to the pK a 9.3 Immobiline, so less Triton was necessary and (ii) only the basic form of TEMED accelerates polymerization, so more is needed for low pH gels. Cobalt, sulfite, and metabisulfite levels were adjusted to scavenge oxygen quickly [22]. After adding APS as the initiator and TEMED as the polymerization accelerator, the liquid mixture was introduced to the side of the device, where it was drawn in by capillary action.…”

Rapid free-flow IEF is achieved in a microfluidic device by separating the electrodes from the focusing region with porous buffer regions. Moving the electrodes outside enables the use of large electric fields without the detrimental effects of bubble formation in the active region. The anode and cathode porous buffer regions, which are formed by acrylamide functionalized with immobilized pH groups, allow ion transport while providing buffering capacity. Thermoelectric cooling mitigates the effects of Joule heating on sample focusing at high field strengths (approximately 500 V/cm). This localized cooling was observed to increase device performance. Rapid focusing of low-molecular-weight p/ markers and Protein G-mouse IgG complexes demonstrate the versatility of the technique. Simulations provide insight into and predict device performance based on a well-defined sample composition.

“…For instance, oxygen scavenging by sulfite compounds is an important task to inhibit corrosion in industrial water circuits. In chemical engineering and mass transfer studies the cobalt‐catalysed reaction of sulfite to sulfate has been intensively investigated [Scheme , (1)] , , , . Mostly, oxygen and its consumption is indicated by ruthenium complexes and their fluorescence abilities as mentioned above by LIF.…”

Reactive bubbly flows are at the heart of multiphase flows which are a major topic in chemical engineering since many bulk chemicals are produced in bubbly flows. However, the factors determining product yield and selectivity are often subject of complicated mass transfer effects. Herein, we describe the latest developments in the detection of mass transfer [a] is holding a permanent position in the Herres-Pawlis group at RWTH Aachen University for advanced spectroscopy, density functional calculations and X-ray crystallography. He studied Chemistry at the University of Paderborn and finished his PhD thesis at TU Dortmund in 2011 on the coordination chemistry of late transition metals for catalysis and bioinorganic chemistry. Then, he moved to LMU Munich and turned to the theoretical description of N-donor transition metal systems with focus on copper-dioxygen chemistry. In 2013, he was awarded with the Römer-Postdoc Prize.
