The experimental determination of slice profiles excited by applying radiofrequency pulses in the presence of a gradient generally results in magnitude profiles. The conditions necessary to obtain a phase-sensitive picture of the profile of a slice are dis ...
The electrochem. oxidn. of phenol for wastewater treatment was studied on doped SnO2 anodes. Anal. of reaction intermediates and a C balance showed that the main reaction is oxidn. of phenol to CO2. This unexpected behavior of the SnO2 anode is explained b ...
It is demonstrated, on the grounds of simulations, how 270 degrees Gaussian pulses can be used for slice selection in nuclear magnetic resonance imaging experiments. It is shown that the usual gradient reversal procedure can be omitted if the selective 90 ...
The chem. redn. of anthraquinone(I) has at least 2 disadvantages on the industrial scale; therefore, an electrochem. method was developed. The electrochem. redn. of I is done in a 2-compartment cell using concd. H2SO4 (15-17 mol/dm3) as the electrolyte at ...
The electrochem. oxidn. of PhOH in wastewater was studied using Pt and DSA anodes. Anal. of reaction intermediates and measurements of current efficiency have shown that traditional anode materials (Pt, Ti/IrO2, Ti/RuO2, Ti/PbO2) give relatively low curren ...
The aim was to examine the anodic oxidn. of some benzene derivs. (model org. pollutants) at Pt and DSA (dimensionally stable anodes) type anodes to elucidate the possibilities of the electrochem. method and to elucidate the mechanism of the reaction. ...
Electrochemistry can bring important contributions to current applications, such as organic synthesis or wastewater treatment. In an environmental context, electrochemical processes are interesting substitutes to the conventional wastewater treatment techn ...
The photoelectrochem. properties of nanostructured highly porous TiO2 electrodes with different thicknesses (2 to 38 μm) were investigated. The effects of electron acceptors, such as oxygen and iodine, in the electrolyte were studied by action spectra meas ...
To overcome ammonia inhibition in animal cell culture, a method utilizing porous polytetrafluoroethylene membranes with an assocd. pH gradient was investigated. Model expts. without cells were carried out in three different reactor configurations suitable ...
The title compds., useful in the prodn. of dye intermediates, are prepd. in acid media in an electrolysis cell whose electrodes are sepd. by a membrane. At the cathode, anthraquinones are reductively cyclized with glycerol [56-81-5] to give the correspondi ...
