Seasonal Shifts in the Use of Green and Brown Food Resources by a Dominant Stream Grazer Open
Streams in deciduous forests experience seasonally distinct pulses of primary production and leaf litter input every year as a result of riparian leaf phenology. Many benthic invertebrates have evolved to harvest one or the other of these …

Project EcoFuel: Renewable Electricity-Based, Cyclic and Economic Production of Fuel Open
E-fuels, produced from CO 2 using renewable electricity, currently suffer from low energy efficiency, hence high energy demand, related high cost and are therefore not yet produced at industrial scale. To be commercially viable, e-fuels pr…
