Ladder-like energy-relaying exciplex enables 100% internal quantum efficiency of white TADF-based diodes in a single emissive layer.
Development of white organic light-emitting diodes based on purely thermally activated delayed fluorescence with a single-emissive-layer configuration has been a formidable challenge. Here, we report the rational design of a...
Quantifying wind-induced impacts on particulate Cu footprint in the Yangtze Estuary.
Under two wind conditions, a polar coordinated segmented quantification method (PCSQM) taking the easternmost point of Chongming Island (121°59'20″E, 31°29'38″N) as the origin of the coordinate was proposed to quantify...

Feb 12, 2020
A recent study by Yuan et al., [Ref. 11] published in Nature Genetics, demonstrated multidimensional molecular alterations of mitochondrial DNA in human cancers and provide an on-line catalogue of mitochondrial genomes in many...
Optimisation for interconnected energy hub system with combined ground source heat pump and borehole thermal storage
Da Huo, Wei Wei, Simon Le Blond
Dec 01, 2018
Ground source heat pumps (GSHP) give zero-carbon emission heating at a residential level. However, as the heat is discharged, the temperature of the ground drops, leading to a poorer efficiency. Borehole inter-seasonal thermal...
