    Chemists led by Beckman researcher Xiao Su have demonstrated that water remediation can be powered in part — and perhaps even exclusively — by renewable energy sources. Using electrochemistry to separate different particles within a solution (also known as electrochemical separation) is an energy-efficient strategy for environmental and water remediation: the process of purifying contaminated water...

    A better way to wirelessly charge over long distances has been developed at Aalto University. Engineers have optimized the way antennas transmitting and receiving power interact with each other, making use of the phenomenon of “radiation suppression.” The result is a better theoretical understanding of wireless power transfer compared to the conventional inductive approach, a significant advancement in the field.

    Charging over short distances, such as through induction pads, uses magnetic near fields to transfer power with high efficiency, but at longer distances the efficiency dramatically drops...

    Researchers Achieve Historic Milestone in Energy Capacity of Supercapacitors

    July 20, 2023, Categories  Physics, Technology/Electronics

    A landmark study led by Luis Echegoyen, Ph.D., professor emeritus at The University of Texas at El Paso, and Marta Plonska-Brzezinska, Ph.D., of the Medical University of Bialystok, Poland (not pictured), was recently featured in the journal Scientific Reports, which is published by leading research publisher Nature Portfolios. It describes how they have achieved the highest level of energy storage — also known as capacitance — in a supercapacitor ever recorded.
