Stephen Cramer of the University of California, Davis, in Davis, California, was presented with the EAS Award for Outstanding Achievements in Vibrational Spectroscopy at the Eastern Analytical Symposium (EAS), in Princeton, New Jersey, on November 13. Cramer is an advanced light source professor at UC Davis.
Cramer’s PhD thesis work under Keith Hodgson involved the first extended X-ray absorption fine structure (EXAFS) studies of metalloenzymes at the newly founded Stanford Synchrotron Radiation Project, along with Raman spectroscopy and coherent anti-stokes Raman spectroscopy (CARS) with Bruce Hudson. Following work as a National Institutes of Health (NIH) postdoctoral researcher at California Institute of Technology, Cramer joined Exxon Research in New Jersey, followed by Schlumberger-Doll Research, then continued to the National Synchrotron Light Source at Brookhaven National Laboratory. He then joined UC Davis in a joint position with the Lawrence Berkeley National Laboratory.
Cramer’s research has focused on synchrotron-based spectroscopic techniques for chemicalcharacterization of biological systems and complex materials. Despite heavy involvement with X-rays, vibrational spectroscopy has remained dear to his heart. His favorite technique, nuclear resonance vibrational spectroscopy (NRVS), merges these two field-a synchrotron x-ray experiment that provides vibrational information. His current research emphasizes the enzymes that fix nitrogen (nitrogenase) or produce hydrogen (hydrogenase).
Cramer has been honored with the ACS Spectrochemical Analysis Award, the Edward Stern Outstanding Achievement Award from the International X-Ray Absorption Society, the Lu Jiaxi Lectureship from Xiamen University, the New York Society for Applied Spectroscopy Gold Medal, a Humboldt Foundation Research Award, and an Einstein Visiting Fellowship at TU-Berlin, and has been named an AAAS fellow.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
