Jülich scientists have presented a new concept that permits currents ten times greater during charging and discharging of solid-state batteries than previously described in the technical literature. All components have been fabricated from phosphate compounds which fit together very well both chemically and mechanically.
Increased nitrogen dioxide concentrations of more than 45 micrograms per cubic meter of air are not an isolated case, a measurement campaign in Düsseldorf by regional public-broadcasting institution WDR has shown. The values were lower away from busy roads. After the analysis, Dr. Robert Wegener from the mobile Jülich measurement laboratory MOBILAB emphasises that the exceptionally high data density would now allow the distribution of nitrogen oxides to be represented more precisely.
Scientists at Forschungszentrum Jülich put a system of reversible high-temperature fuel cells into operation that achieves an electrical efficiency in hydrogen operation of more than 60 per cent. No other research team has reported such a high value so far.
A research team in which Jülich was involved improved the modelling of failures of technical infrastructure networks. In the journal “Nature Communications”, they presented a framework for analysis based on the example of electrical power networks, which takes into account the event-based character of the chain reaction and also factors in the specific network dynamic influences.
