Yuanyuan Li: Multimodal approach for determining the electronic and atomic structure of ceria supported Pt single atoms catalyst

Single atoms catalysts (SACs) have been heavily investigated in the recent years because of their good catalytic properties (especially activity and selectivity) for many chemical reactions . In addition to that, in SACs, the supported metals are used with extremely high efficiency compared to their nano counterparts. That is very important for noble metals, which […]

Chris Glover: Australian XAFS: Past, present, and a Br-ght future

The Australian XAFS community started from small beginnings and currently, XAFS is one of the most oversubscribed techniques at the Australian Synchrotron. The community has been fostered by access to facilities; initially the Australian National Beamline Facility (ANBF) at the Photon Factory, to more recently the XAS beamline at the Australian Synchrotron. The ANBF was […]

Dooshaye Moonshiram: Electronic and Structural Configurations of Earth-Abundant Water Splitting Catalysts and Spin Crossover Complexes

The solar light-driven splitting of water for hydrogen fuel production is a promising alternative to fossil fuels due to their rapid depletion and concomitant environmental pollution. The design of light-driven devices composed of organic, inorganic or hybrid materials that can mimic natural photosynthetic processes is extremely desirable. An essential component of such systems is the […]

Wantana Klysubun: XAS capability and science at the Thailand synchrotron

100/year) and number of users' publications (> 60/year). Experiments can be done in transmission, fluorescence-yield and electron-yield modes. Additionally, in situ measurements are possible. To demonstrate XAS capability at SLRI, highlighted research in various fields will be presented, i.e. Fe site determination on a grafted Zr-based MOF catalyst , monitoring dynamic phase transition of olivine […]

Hao Yuan: Ptychography and 4D imaging by spectro-ptycho-tomography

Coherent X-ray scattering (diffraction) methods will be key to exploiting the high coherent flux of 4th generation synchrotron sources. Ptychography is a coherent diffraction technique that allows rapid, reliable inversion of arrays of diffraction images into real space images by using overlapping spatial areas to constrain the reconstruction . While ptychography is quite well developed […]

Li Song: Soft X-ray endstaions at the Hefei Light Source and some applications of XAS

Hefei Light Source (HLS) is the first dedicated synchrotron radiation facility in China with electron ring energy of 0.8 Gev, which is located on the West Campus of the University of Science and Technology of China (USTC). With the completion of twice constructions and recent upgradation, HLS become a fully upgraded soft X-ray synchrotron radiation […]

Matthew Marcus: Soft x-ray spectromicroscopy in extraterrestrial materials

Extraterrestrial materials such as meteorites and interplanetary dust particles are often very complex and non-uniform, with diverse species within a small sample. In some cases, especially for the products of sample-return missions, the available samples are small and precious. X-ray micro- and nano-spectroscopy are ideal complements to other methods such as TEM and nano-SIMS. In […]

Andy Aquila: The Tender X-ray Imaging (TXI) instrument at the LCLS

This presentation will take place at 6 pm Monday, Seattle (Los Angeles) time / 9 am Tuesday, Beijing time using Zoom. For the Zoom link and password, visit  within 30 minutes of the beginning of the presentation. The Linac Coherent Light Source (LCLS) upgrade to a high repetition source offers new avenues to pump/probe […]

Thomas Penfold: Towards the Rapid Analysis of XANES for Complex Systems using Deep Neural Networks

X-ray spectroscopy delivers strong impact across the physical and biological sciences by providing end users with highly detailed information about the electronic and geometric structure of matter. To decode this information in challenging cases, e.g., in operando catalysts, batteries, and temporally evolving systems , advanced theoretical calculations are necessary. The complexity and resource requirements often […]

Liang Zhang: In situ/operando XAS for energy storage materials

Rechargeable batteries (Li-ion batteries and beyond) have received extensive attention as powerful boosters for the development of human society. However, the application of rechargeable batteries is still hindered by low energy density, serious voltage hysteresis, and long-term degradation. Therefore, it is of great importance for understanding the underlying redox reaction and capacity fading mechanisms to […]

Susan Cumberland: Determining uranium geochemistry within natural organic-matter rich environments using XAS and XFM techniques

  Analysing metals within environmental samples using wet chemistry can pose analytical problems, particularly with carbon-based and solid samples. X-ray absorbance spectroscopy (XAS) analysis is one alternative approach, able to target elements of interest whilst avoiding matrix interference from low mass elements (e.g. carbon). One element that is particularly suited to XAS is uranium (U), […]
