• Although the advantages of using grazing incidence (GI) techniques in X-ray scattering and spectroscopy have been known for a long time (Yoneda and Horiuchi 1971), the use of such geometry has only been developed fully with the advent of highly collimated X-ray sources, particularly synchrotrons.

  • Experimental instrumentation includes microfocussing optics, an 8-circle goniometer, 2D CCD detector, and multielement x-ray fluorescence detectors for time- and spatially-resolved x-ray scattering, reflectivity, and XAFS to study a variety of materials, environmental, and biological problems. (nd.edu)
  • Here we used X-ray absorption spectroscopy at cryogenic temperatures and transmission electron microscopic imaging techniques to chemically characterize and spatially resolve the mechanism of biomineralization in those microorganisms. (pnas.org)
  • Applies time-reslved multiphoton ionization spectroscopy to the study of the second photodissociation of an oxygen-chlorine compound. (ebscohost.com)
  • Beamlines will be avaiable for participants interested in hard- or soft x-ray spectroscopy. (bnl.gov)
  • To that end, the group is part of the Materials Research Collaborative Access Team (MRCAT) a multiple-institution consortium that constructed and now operates two x-ray beamlines at the Advanced Photon Source located at Argonne National Laboratory . (nd.edu)
  • We are at the forefront of method and instrumentation development for X-ray and VUV spectroscopy in the temporal and spatial domains to gain novel insights into the elemental composition, the chemical state, and reaction dynamics. (psi.ch)
  • Single particle inductively coupled plasma mass spectroscopy (spICP-MS) has been suggested as a powerful tool for routine nanometrology efforts. (mdpi.com)
  • The combination of X-ray crystallography and rapid cryo-trapping methods has enabled the visualization of catalytic intermediates in a variety of enzyme systems. (portlandpress.com)
  • There have been considerable advances in the last 10 years in both the demand for and availability of instrumentation for the spectroscopy of protein crystals and, more recently, nucleic acid crystals. (portlandpress.com)
  • This pressure is unlikely to decrease over the next decade or two as projects such as the Human Genome Project, which alone is expected to produce some tens of thousands of new proteins, whose structures will need to be investigated using X-ray methods in order to determine structure-function relationships, continue to evolve. (esrf.eu)
  • On this bases, the present talk will be focused on new methods for the rapid screening of (photo-) electrocatalysts activity using the scanning electrochemical microscope (1,2) and on the use of X-ray absorption spectroscopy for a better understanding of the (photo-) electrochemical behaviour of two model systems: IrO2 and α-Fe2O3/IrO2.

  • An interpretation of the spectral features is given using a monoelectronic description of the transitions involved in the X-ray absorption process. (ipgp.fr)
  • The assignment of experimental pre-edge peaks in terms of 1s-3d transitions makes it possible to determine the magnitude of the 3d-splitting, which is similar to the 10 Dq crystal-field value determined from optical absorption spectroscopy. (ipgp.fr)
  • Low-dose X-ray damage has been shown to have a variety of effects, including redox changes in both metals and organic cofactors [ 5 , 8 ] and breakage of radiation-sensitive bonds in both protein and ligands [ 9 , 10 ]. (portlandpress.com)
