Progress in catalysis is driven by society's needs. The development of new electrocatalysts to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks for today's scientists and enginee ...
The Swiss Energy Strategy 2050 pursues an ambitious transition to a more renew- able and efficient energy future, combining CO2 and energy saving targets with a phase-out of nuclear electricity generation. This transition poses challenges not only for the ...
Among the several approaches for harnessing solar energy and converting it into electricity, dye-sensitized solar cells (DSSC) represent one of the most promising methods for future large-scale power production from renewable energy sources. In these cells ...
Modern concepts for grids are being developed owing to the increasing stress put on the electrical producers and the burgeoning need for thermal demands due to varying climate conditions. The increasing awareness of the depletion of natural resources has a ...
CAMEA (Countinuous Angle Multiple Energy Analyser) is a new concept for analysing inelastically scattered neutrons with high efficiency. It contains many (up to 10) vertically focusing analyser arrays behind each other, analysing the scattered neutrons wit ...
Novel star-shaped hole transporting materials with a triazine unit have been synthesized. When the new Triazine-Th-OMeTPA was used as a hole transporting material in perovskite solar cells, the power conversion efficiency reached 12.51% under AM 1.5 G (100 ...
According to the International Energy Agency, CO2 emissions have to be cut by a factor 2 if one wants to mitigate the effect on the climate change to an acceptable limit. To reach this target, efficient use and conversion of energy resources is expected to ...
Biorefinery concepts refer to the integrated production of food, fuel, power, commodity chemicals, and polymers from biomass, mimicking the structure of a fossil-based refinery. The use of lignocellulosic biomass as feedstock for biorefineries has been pro ...
A non-isolated DC-DC converter is presented, based on the current diverter principle. The converter is foreseen for larger photovoltaic plants or other DC collection networks for renewable energy sources. The topology allows the DC-DC conversion as step-up ...
Innovation of the energy saving and optimization of the renewable sources are the most important sides of the building sector in the last years. Considering that buildings consume more than 40% of all the energy we use and about 50% of it is used for the c ...
