A new mathematical model for predicting variations in solar irradiance has been developed at Uppsala University. It may help to promote more efficient use of electricity from solar energy. In tests of various data models, the model proved capable of making highly reliable forecasts, and emerged as the best for this purpose in some respects. The results have now been published … [Read more...] about New solar forecasting model performs best
Extensive review of spin-gapless semiconductors: Next-generation spintronics candidates
A University of Wollongong team has published an extensive review of spin-gapless semiconductors (SGSs) . Spin gapless semiconductors (SGSs) are a new class of zero gap materials which have fully spin polarised electrons and holes. The study tightens the search for materials that would allow for ultra-fast, ultra-low energy 'spintronic' electronics with no wasted dissipation of … [Read more...] about Extensive review of spin-gapless semiconductors: Next-generation spintronics candidates
Why are plants green?
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms -- from plants to bacteria -- have developed numerous tactics. Scientists have been unable, however, to identify the underlying design principle. An international team of scientists, led by physicist … [Read more...] about Why are plants green?
AI could help improve performance of lithium-ion batteries and fuel cells
A new machine learning algorithm allows researchers to explore possible designs for the microstructure of fuel cells and lithium-ion batteries, before running 3D simulations that help researchers make changes to improve performance. Improvements could include making smartphones charge faster, increasing the time between charges for electric vehicles, and increasing the power of … [Read more...] about AI could help improve performance of lithium-ion batteries and fuel cells
Self-powered alarm fights forest fires, monitors environment
Smokey the Bear says that only you can prevent wildfires, but what if Smokey had a high-tech backup? In a new study, a team of Michigan State University scientists designed and fabricated a remote forest fire detection and alarm system powered by nothing but the movement of the trees in the wind. As detailed in the journal Advanced Functional Materials, the device, known as … [Read more...] about Self-powered alarm fights forest fires, monitors environment
