With gasoline prices still hovering near $4 per gallon, scientists at Brookhaven Lab s Center for Functional Nanomaterials (CFN) are helping to develop electric vehicles capable of driving hundreds of miles on a single charge. A new compound of five tin atoms and one iron atom (FeSn
5) created at the CFN is another development along the road to higher capacity lithium-ion batteries for those vehicles of the future.
Compared to other types of rechargeable batteries, lithium-ion batteries weigh less, can store more electricity for longer periods of time, and can handle more cycles of use and recharging. They are used in some electric cars today, but are not yet powerful enough to compete with cars that can travel 300-400 miles on a single tank of gasoline.

HPCwire magazine recognizes two Argonne teams for outstanding achievement in their use of high performance computing.
Two teams of scientists from the U.S. Department of Energy s (DOE) Argonne National Laboratory have won HPCwire Awards, recognizing their innovative use of high performance computing (HPC) to optimize engine design. The awards were presented by HPCwire magazine.
The Readers Choice Award for Best Use of HPC in Energy went to a group of Argonne scientists who used the laboratory s Theta supercomputer to run the largest-ever combustion engine flow simulation. The Readers Choice Award for Best Use of HPC in Industry went to an interdisciplinary team of scientists from Argonne, Aramco Research Center-Detroit and Convergent Science, who used Argonne s supercomputers to resolve
ORNL team performs first neutron diffraction experiments on a running engine
Researchers at Oak Ridge National Laboratory (ORNL) have used neutron diffraction to provide noninvasive measurement of lattice strains inside components of a firing engine, thereby enabling the operando study of complex load states and thermal gradients throughout the solid materials. Their results are published in an open-access paper in
Proceedings of the National Academy of Sciences (PNAS).
Engineering neutron diffraction can nondestructively and noninvasively probe stress, strain, temperature, and phase evolutions deep within bulk materials. In this work, we demonstrate operando lattice strain measurement of internal combustion engine components by neutron diffraction.
Significant Energy Legislation Poised to Become Law with COVID-19 Relief
USA
December 23 2020
The Consolidated Appropriations Act, 2021 (Act), which passed both chambers of Congress on December 21, 2020, for the purpose of funding the government in fiscal year (FY) 2021 and providing COVID-19 relief, also included the most comprehensive bipartisan energy and climate legislation of the past decade. If signed into law, the legislation authorizes over $35 billion for the development of various clean energy technologies, including wind, solar, energy storage, energy efficiency, carbon capture utilization and storage (CCUS), carbon removal, and nuclear energy, primarily through programs run through the U.S. Department of Energy (DOE), and authorizes additional monies to be allocated to emissions-reducing projects through the DOE’s Title XVII loan guarantee program. It also extends and in some cases expands a number of energy tax incentives that support investments in renewable and cl
