Title: In-/ex-situ XAS Studies on Electrode Materials Used in Energy Storage Applications
Date: Wednesday, January 26, 2022
Time: 1:00 pm CDT
Abstract:
The usage of advanced characterization techniques like an X-ray Absorption Spectroscopy (XAS) is so significant in terms of understanding of the direct correlation between atomic structural variations to electrochemical performance and failure mechanisms in the energy storage applications and catalyst studies. The XAS spectra typically consists of two main regions: the X-ray absorption near edge structure (XANES), sensitive to electronic structure (i.e. valence state) and local coordination environment; and the extended X-ray absorption fine structure (EXAFS), sensitive to local structure (i.e. inter-atomic distance, identity, and coordination number). If the EXAFS region obtained after the absorption can be modeled with a theoretical local structure, a detailed structural information can be extracted by observing the changes or variations at the atomic level occurring during the electrochemical cycle. In this talk, the synthesis and characterization of several electrode and catalyst materials produced in the form of nano-powders, ceramics, and composites will be presented, as well as both the fabrication and the in-situ/ex-situ investigation of electrochemical devices such as Li-ion battery and Fuel-cells. In this study, the collected XAS data was analyzed and modelled using the ATHENA and ARTEMIS software for both XANES and EXAFS regions respectively, to determine the structural changes both in the electronic state and local environment of absorbing elements occurring during electrochemical cycles. In this regard, the causes of both failure and improvements will be discussed based on the analysis results obtained from extensive studies carried out on various electrode and catalyst materials by using synchrotron-based x-ray experimental techniques, as well as their electrochemical investigations.

CONEXS Workshop 2022
CONEXS aims to support the next generation of researchers to study X-Ray Spectroscopy.
The CONEXS (Collaborative Network for X-Ray Spectroscopy) Workshop 2022 will be an in-person event hosted by Newcastle University, UK, on the 28-30 March 2022. The workshop will train PhDs and PDRAs (especially experimentalists) in the theory of X-ray spectroscopy and how to simulate/interpret their spectra, with a focus on FEFF and Quantum ESPRESSO. The workshop will be a mix of lectures and practical exercises, the lectures will be recorded and made available on the CONEXS website following the event.
The workshop is free to attend and accommodation and all meals will be provided.
The workshop will be led by:
Joshua Kas – Research Assistant Professor, University of Washington
Matteo Calandra – Full Professor, University of Trento
FEFF is a software program used in x-ray absorption spectroscopy. It contains self-consistent real space multiple-scattering code for simultaneous calculations of x-ray-absorption spectra and electronic structure. Output includes extended x-ray-absorption fine structure (EXAFS), full multiple scattering calculations of various x-ray absorption spectra (XAS) and projected local densities of states (LDOS). The spectra include x-ray absorption near edge structure (XANES), x-ray natural circular dichroism (XNCD), and non-resonant x-ray emission spectra.
The SRI conference will now take place from Monday, 28 March to Friday, 1 April 2022 on-site in Hamburg (Germany).
The new deadlines for the SRI conference are now:
Re-opening abstract submission: 1 April 2021
Deadline abstract submission: 1 October 2021
Early bird registration until 15 January 2022
Registration deadline 15 February 2022
International Conference on Synchrotron Radiation Instrumentation (SRI) is a unique, large and the most significant international forum held every three years in the community of synchrotron radiation (SR) and free electron laser (XFEL).
This triennial conference is the prime forum to highlight connections between synchrotron radiation instrumentation, science, and society. It also provides opportunities for discussion and collaborations among scientists and engineers around the world involved in development of new concepts, techniques, and instruments related to synchrotron radiation and free electron laser research.
IWXM 2022
The 7th International Workshop on Metrology for X-ray Optics, Mirror Design and Fabrication (IWXM) will be held in Berlin, Germany, from April 5th-7th, 2022 as a satellite workshop of the Synchrotron Radiation and Instrumentation-SRI conference 2022.
It will provide a forum for presentation and discussion on the latest developments in X-ray optics like mirrors, gratings, reflection zone plates, etc. with particular regard to improvements in metrology, deterministic surface finishing, developments in ML-coatings, simulation of optical systems performance. Contributions from private companies are welcome.
The workshop will include a series of oral and poster presentations as well as a tour of the BESSY-II synchrotron radiation source. The workshop will be held as a hybrid-event with the option of participation in person as well as virtual.
