Researchers at the University of Minnesota have achieved a new material that will be pivotal in making the next generation of high-power electronics faster, transparent and more efficient. This artificially designed material allows electrons to move faster while remaining transparent to both visible and ultraviolet light, breaking the previous record. The research, published in Science … Read more
Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held back by a fundamental physical limit that prevents transistors from operating below a certain voltage. This limit, known as “Boltzmann tyranny,” hinders the energy efficiency of computers … Read more
Rice University researchers have developed an electrochemical reactor that has the potential to drastically reduce energy consumption for direct air capture, the removal of carbon dioxide directly from the atmosphere. The new reactor design could be a part of the solution to the pressing problem of emission impacts on the climate and biosphere by enabling … Read more
Penn State professor of chemistry Joseph Cotruvo, Jr. and graduate student Wonseok Choi have been researching ways to separate rare earth elements using reengineered bacterial proteins that are found in nature. Credit: Michelle Bixby/Penn State A newly discovered protein naturally houses an unusual binding site that can differentiate between rare earth elements, and researchers at … Read more
