QLEDs â light-emitting diodes that rely on nanocrystals called quantum dots â are usually made with toxic heavy metals. A strategy has been developed to make QLEDs with a performance comparable to that of commercially available technologies but using a more environmentally friendly alloy of zinc, selenium, telluriu

Human footprint on estuarine tidal hydrodynamics - Nature Geoscience
4+ mon, 2+ week ago (1763+ words) Changes in tidal range were analysed by interpolating along-estuary tidal range profiles and identifying key parameters: tidal range at the estuary mouth, maximum tidal range and maximum change location. Mean high water (MHW) and mean low water (MLW) were calculated…...
