EXAFS analysis using FEFF and FEFFITJournal of Synchrotron Radiation - Tập 8 Số 2 - Trang 96-100 - 2001
M. Newville
Some of the advanced EXAFS analysis features of FEFF and FEFFIT are described. The scattering path formalism from FEFF and cumulant expansion are used as the basic building blocks of EXAFS analysis, giving a flexible and robust parameterization of most EXAFS problems. The ability to model EXAFS data in terms o...... hiện toàn bộ
High-resolution thermal imaging with a combination of nano-focus X-ray diffraction and ultra-fast chip calorimetryJournal of Synchrotron Radiation - Tập 21 Số 1 - Trang 223-228 - 2014

A microelectromechanical-systems-based calorimeter designed for use on a synchrotron nano-focused X-ray beamline is described. This instrument allows quantitative DC and AC calorimetric measurements over a broad range of heating/cooling rates (≤100000 K s−1) and temperature modulation frequencies (≤1 kHz). The calorimeter was used for high-resolution thermal imaging of...... hiện toàn bộ

Synchrotron-based X-ray absorption near-edge structure (XANES) spectroscopy is becoming an increasingly used tool for the element speciation in complex samples. For phosphorus (P) almost all XANES measurements have been carried out at the K-edge. The small number of distinctive features at the P K-edge makes in some cases the identifica...... hiện toàn bộ
XDS: a flexible beamline for X-ray diffraction and spectroscopy at the Brazilian synchrotronJournal of Synchrotron Radiation - Tập 23 Số 6 - Trang 1538-1549 - 2016

The majority of the beamlines at the Brazilian Synchrotron Light Source Laboratory (LNLS) use radiation produced in the storage-ring bending magnets and are therefore currently limited in the flux that can be used in the harder part of the X-ray spectrum (above ∼10 keV). A 4 T superconducting multipolar wiggler (SCW) was recently installed at LNLS in order to improve the photon flux above ...... hiện toàn bộ
X-ray powder diffraction at the XRD1 beamline at LNLSJournal of Synchrotron Radiation - Tập 23 Số 6 - Trang 1501-1506 - 2016

Various upgrades have been completed at the XRD1 beamline at the Brazilian synchrotron light source (LNLS). The upgrades are comprehensive, with changes to both hardware and software, now allowing users of the beamline to conduct X-ray powder diffraction experiments with faster data acquisition times and improved quality. The main beamline parameters and the results obtained for different ...... hiện toàn bộ
