SSCU is organizing a series of lectures on synchrotron-based techniques from December 17 and 18, 2025 at A-104 Lecture hall, Chemical Sciences Building. Prof G. Sankar from University College London will teach these techniques and data processing.
We request interested candidates to register for the lecture series at this link https://forms.gle/Q8GHQoqjD9ffHFGt7
Here are the details of the lectures
Lecture series: Synchrotron X-ray Techniques and Data Processing
Lecture 1: Synchrotron Radiation and X-ray diffraction (S-XRD), Wednesday, December 17, 2024 (10 am to 12 pm)
Synchrotron radiation – Generation, advantages over laboratory X-rays. Sample preparation, data collection, instrumentation for High-resolution powder XRD, and Structural characterization of materials including catalysts under in situ conditions. X-ray diffraction at energies and introduction to PDF methods.
Lecture 2: X-ray absorption spectroscopy – XANES, Wednesday, December 17, 2024 (2 pm to 4 pm)
X-ray absorption spectrum – X-ray absorption Near Edge Structure (XANES) and their use in determining (a) Oxidation state, (b) coordination environment, (c), in some cases, phase identification. Linear Combination Fitting and Difference methods. Some examples will be discussed in detail.
Lecture 3: X-ray absorption fine structure (EXAFS), and In-Situ Operando technique in Synchrotron Thursday, December 18, 2024 (10 am to 1 pm)
EXAFS: Fundamentals of X-ray absorption fine structure, Simple theoretical Description. How to extract EXAFS from the raw data and how to determine the local structure around a given atom will be shown. Some examples will be discussed in detail.
In-Situ and operando techniques will be explained, including the design of in situ cells and how to plan the experiment. What information one can gain through these in situ time-resolved measurements? Some examples will be shown to highlight the power of this approach.
Lecture 5: Data processing and hands-on training on software, Thursday, December 18, 2024 (2 am to 5 pm)
Processing PDF and XAS data and analysis procedures will be discussed here.
In all these sessions, the final 30 minutes to 1 hour can be dedicated to questions from the participants and discuss their own examples on how to tackle the scientific questions they have.
