Modern free electron lasers provide intense X-ray pulses with 10^12 photons within ~10-100 femtoseconds. Such pulses enable new experimental techniques and provide unique opportunities for investigation of electronic and nuclear […]

The safe use and disposal of UO2 based nuclear fuels relies on the stability of their material properties, under extreme conditions of temperature and irradiation, and with constantly evolving chemical […]

Databases of x-ray fluorescence line energies such as those of Deslattes (2003) and Bearden (1967) are critical to the calibration of any analytical tools that identify elemental compositions by their […]

The conservation of marine archaeological wood is complicated by the presence of iron and sulfur. The sulfur originates from sulfate ions in seawater being transformed by sulfur reducing bacteria, and […]

Using High-Energy-Resolution-Fluorescence-Detection (HERFD), one can sharpen the pre-edge structures revealing their multiplet nature. In ionic systems, they can be calculated from the transition from the 3dN ground state to the […]

We will look at how electrochemically active materials such as batteries can be studied in a concerted way by tuning to relevant resonant x-ray absorption at both the soft and […]

I will present details of the TES Beamline at the National Synchrotron Light Source II, covering its design, commissioning, and early results. Its scientific mission includes static and in-situ/operando XRF […]

Modern electronic structure theory and computational methods now permit efficient calculations of ground state properties, as exemplified by the tabulation of many-thousands of structures in the Materials Project . Complementary […]

The presentation will be a collection of thoughts that I find interesting for the experimentalist employing hard X-ray photon-in/photon-out spectroscopy with a wavelength dispersive instrument. I would like to draw […]

The new painting materials used by the Impressionists, Fauvists, and Expressionists were critical components of their break with traditional modes of representation. These artists heavily exploited the synthetic organic and […]

Presented will be a discussion of efforts to employ a wavelet transform (WT) analysis towards the quantitative structural determination of discrete molecular systems using an EXAFS analysis. Unlike a transition […]

Great strides have been made over the past decade in the theory and calculation of X-ray and related spectra. Some advances involve predictions of material properties such as structure or […]
