A Sandia-led team has developed a way to make a magnetic material that could lead to lighter and smaller, cheaper and better-performing high-frequency transformers, needed for more flexible energy storage systems and widespread adoption of renewable energy. The work is part of a larger, integrated portfolio of projects funded by Department of Energy’s (DOE) Energy…
Unique Phononic Filter Could Revolutionize Signal Processing Systems
A unique filtering technology that combines light and sound waves on a single chip is expected to better detect radar and communications frequencies. “We have developed a powerful signal filtering technology that could revolutionize signal processing systems that rely solely on conventional electronics,” said Patrick Chu, manager of applied photonic microsystems for Sandia National Laboratories. The radio…
‘Iron Sun’ is Key to How Stars Transmit Energy
Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band — the section of the solar interior…
Evaluating Powerful Batteries for Modular Grid Energy Storage
Sandia National Laboratories has begun lab-based characterization of TransPower’s GridSaver, the largest grid energy storage system analyzed at Sandia’s Energy Storage Test Pad in Albuquerque, N.M. Project lead David Rosewater said Sandia will evaluate the 1 megawatt, lithium-ion grid energy storage system for capacity, power, safety, and reliability. The lab also will investigate the system’s…
