In 1991, Gratzel and co-workers published promising results from dye-sensitized, nanocryst., photoelectrochem. solar cells (DNSCs), with huge internal surface areas. A Gratzel cell consists of a dye-sensitized TiO2-electrode, a platinized counter electrode ...
Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diam. of the channels (.apprx.100 mm) leads to a short radial diffusion time, a narrow residence time distribution, and a l ...
The aim of this paper is to present a global approach to dynamic optimization of batch emulsion polymerization reactors using a stochastic optimizer. The objective is to minimize the final batch time with constraints on the final conversion and molecular w ...
With reactivity being the most important integral reactor physics quantity - and simultaneously the one that can be measured with the highest accuracy there is a great interest in understanding how possible space- and energy-dependent data and/or modeling ...
In this work, a new type of short water vapor treatment of the interface between the p- and i-layer is presented. This novel treatment is performed under vacuum below 1 mbar for 5 min and considerably reduces the i-layer boron contamination in amorphous si ...
Reduced activation ferritic/martensitic (RAFM) steels are the reference structural materials for future fusion reactors. They have proven to be a good alternative to austenitic steels for their higher swelling resistance, lower damage accumulation and impr ...
Single Photon Emission Computerised Tomography, a non-destructive imaging technique particularly employed for medical diagnoses, has been adapted and applied for the first time to the study of two-dimensional reaction rate distributions within lightly acti ...
Disinfection of some microorganisms is characterized by a lag-phase (a minimum required ozone exposure until disinfection occurs). This phenomenon is easy to model in laboratory batch reactors but not in continuous flow mixed reactors. This paper introduce ...
The shift toward low-enrichment uranium (LEU) fuel for gas-cooled high-temperature reactors (HTRs) has revealed a lack of experimental data for validating neutronics codes that are used for the design and licensing of such systems. In the framework of the ...
Theor. anal. of the reactor performance under unsteady-state conditions was carried out. The reactions are described by two kinetic models, which involve the participation in catalytic reaction of two types of active sites. The kinetic model I assumes the ...
