    Notes: Abstract Beginning with a construction based on a C-size (LR-14) battery container ('can'), encased in a strong PMMA-support and fitted with a removable cell top equipped with a manometer and a gas-outlet valve, a second and, finally, a more refined third generation cell was developed. The final (3rd generation) design provides additional options for experimental work. For example, the system can be flushed with inert gas; a regulating gas-flow valve has been fitted to feed precisely a gas chromatograph with the gaseous reaction products and a reference electrode to measure anode and cathode potentials individually has also been incorporated. Since AA cells (LR-6) are the dominant monocell battery size, test cells of the second generation were fitted with an adapter to accomodate either a C- or an AA-size. However, the most recent system was designed exclusively for AA-sized cans. The different cell designs are described and examples of their practical application (e.g., overcharge experiments) are given.

    Notes: Abstract A simple device for taking in situ proton NMR measurements in 1H2O is described. This allows aeration of reactions in a 10 mm diameter NMR tube without modifying the magnet or the probe head. With this device, aerobic biotransformations can be monitored in the NMR-tube placed in the spectrometer. It allows in situ analyses of the transformations, separating the aeration period temporally from the measurement time, not unlike traditional Warburg respiratory experiments. Two reactions determining kinetic and stoichieometric parameters: (i) a biotransformation by a growing Pseudomonas putida culture and (ii) l-phenylalanine oxidation catalysed by l-amino acid oxidase [E.C. 1.4.3.2]; both incubations were contained in the magnet.
