being water. They offer a significant green option as a future carbon-free power source. Like all electrochemical cells they consist of an anode and a cathode in contact with a conducting electrolyte through ... travel between the electrodes hosting the reaction sites. A favoured fuel cell design is one where the electrolyte is a synthetic membrane ...

plastic solar cells used a derivative of fullerene (a sphere-like carbon molecule) as an acceptor, together with a semiconducting polymer such as P3HT – poly(3-hexylthiophene-2,5-diyl) as a donor. They have achieved ... , or as a coating from solution in a continuous process. The plastic device would be lightweight and flexible, and could be scaled ...

battery when positively charged lithium ions fl ow through an electrolyte from a positive lithium-containing electrode to a more negative electrode; electrons then pass through an external circuit to balance ... REAL-TIME MOVIES For this reason, we developed a novel battery to study what happens in the electrode materials while it is actually ...

der University (FAU) Erlangen-Nürnberg have taken a major stride towards the construction of a GaAs-based backscattering spectrometer. The result is a drop in energy resolution to several tens of nano-eV ... has convinced them that a full-scale spectrometer could now be built in a straightforward way providing energy resolution in the order of 50 ...
