Researchers at the DOE’s Brookhaven National Laboratory in the United States have found that a coating of magnesium enhances the characteristics of tantalum, a superconducting material with a lot of potential for creating qubits, the building blocks of quantum computers.
E-Mail Hydrogen is an incredibly powerful fuel, and the ingredients are everywhere--in plain old water. Researchers would love to be able to use it widely as a clean and sustainable energy source. One catch, however, is that a considerable amount of energy is required to split water and make hydrogen. Thus scientists have been working on fabricating materials for photoelectrodes that can use solar energy to split water, creating a "solar fuel" that can be stored for later use. Scientists with the University of Chicago, the University of Madison-Wisconsin and Brookhaven National Laboratory p...
share: Tuning Electrode Surfaces to Optimize Solar Fuel Production An electrode material with modified surface atoms generates more electrical current, which drives the sunlight-powered reactions that split water into oxygen and hydrogen—a clean fuel February 18, 2021 Through a tight coupling of experiment and theory, scientists showed at the atomic level how changes in the surface composition of a photoelectrode play a critical role in photoelectrochemical performance. UPTON, NY—Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a...
