A promising eco-friendly energy harvesting method called solar-thermal technology has a crucial role to play in resolving the crisis of fossil fuel energy.
Researchers from the Department of Chemistry at the University of North Carolina at Chapel Hill have developed silicon nanowires that can convert sunlight into electricity by splitting water into oxygen and hydrogen gas, providing a greener alternative to fossil fuels.
Electrocatalysis is an interface-dominated process, in which the catalyst activity is highly related to the adsorption or desorption behaviors of the intermediates or reactants, or products on the active sites.
Since the 1970s, scientists have known that copper has a special ability to transform carbon dioxide into valuable chemicals and fuels.
Transition metal sulfides have great potential for sodium storage due to their high theoretical capacity and abundance. However, low conductivity and volume expansion limit their high-rate performance and cyclic stability.
Researchers have produced new evidence of how graphene, when twisted to a precise angle, can become a superconductor, moving electricity with no loss of energy.
Due to their easy bandgap tunability and low inter-system crossing loss, semiconductor nanocrystals (NCs) offer tremendous potential as sensitizers for triplet-triplet annihilation up-conversion (TTA-UC).
A recent study published in the journal Carbon focuses on the application of high-powered laser pulses of brief duration for inducing minute defects in lithium-ion battery materials, which in turn improves battery performance.
Hydrogen fuel could be a more feasible option than conventional fossil fuels, according to the University of Surrey scientists who have discovered that a type of metal-free catalyst could add to the advancement of economical and sustainable hydrogen fabrication technologies.
Recently, at Lund University in Sweden, physics researchers were successful in building small solar radiation-collecting antennas—nanowires—using three varied materials that are a better fit for the solar spectrum than the silicon solar cells available at present.
