Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Surface-enhanced Raman scattering (SERS) has been detected for pyridine adsorbed onto the surface of thin (average thickness = 2.0 to 8.8 nm), continuous layers of stainless steel that were laser ablated onto roughened electrodes of silver. The experiments were performed on samples immersed in 0.1M KCl + 0.05M pyridine. The SER spectra changed with applied potential, and the intensities of the spectra decreased with increasing thickness of stainless steel. This procedure opens up SERS to the study of electrochemical phenomena at interfaces between alloys and a wide range of aqueous/gaseous environments
