Unlocking Cryo-EM Excellence: Join Us for an SOS Pipeline Deep Dive!

Are you eager to harness the power of high-resolution cryo-EM but lack the means for sample preparation? Look no further! Our SOS Pipeline is here to help.

We understand that access to cryo-EM sample prep can be a challenge, and we're on a mission to change that. Join our hybrid meeting to discover how the SOS Pipeline can empower your research.

What to Expect:

Insights from ESRF scientists: Uncover the full potential of the SOS Pipeline with guidance from beamline scientists.

Success Stories: Hear first hand experiences from fellow SOS users who've achieved remarkable results.

Your Cryo-EM Journey: Learn how to make the most of this game-changing resource.

Don't miss out on this opportunity to revolutionize your cryo-EM research. Join us and take the next step toward scientific excellence!

This hands-on tutorial is for those scientists who need to write a news article about their upcoming publications for their communication groups. In this session, we will explain how to write an article, be it for an institutional website or to share with the media.

We will work on the structure, the wording and the side elements that can make an article have more impact and reach.

We will work together using a scientific publication as an example. That publication will be distributed to the participants in advance.

Participants are also invited to submit, in advance, their own publication for us to work on during the session. If interested, please send us your submission by 15th January 2024.

Lunch will be provided.

Diffraction and diffusion are among the most used characterization techniques at synchrotron sources.
PyFAI has been designed to reduce data acquired with area-detectors to make them interpretable by scientists. Besides the ESRF, most X-ray sources around the world use it.

This tutorial will present you the usage of the software and introduce some advanced analysis techniques such as outlier-rejection.

Three exercises will allow you to practice different steps of the analysis:
* Calibration of an experimental setup (SAXS/powder/PDF...)
* Diffraction mapping or XRD-CT experiment
* Bragg-peak extraction

You will need a laptop and can also bring some data you wish to analyze.

This tutorial aims to give participants the bases for carrying out in autonomy a complete XAS experiment at the LISA beamline. As a first step, we will briefly recall the bases of XAS theory and data analysis. Then, we will introduce the principles and practical aspects of sample preparation and spectra will be collected at the beamline on the samples prepared by the participants. Finally, a complete quantitative analysis will be carried out on the collected spectra.

It is recommended that participants come with their laptops with the XAS data analysis codes installed. It could be either:

DEMETER ( https://bruceravel.github.io/demeter/ )

or

LARCH ( https://xraypy.github.io/xraylarch/ )

After a short introduction on XANES, X-Ray Raman, valence to core X-ray Emission spectroscopy and the specificities of FDMNES, most of the tutorial will be devoted to:

• Learn the basic use of FDMNES
• Make a series of numerical experiments to see the sensitivity of the spectroscopies to the material geometry and the beam polarization.
• Start a case study proposed by the participants.

Coherent X-rays are a unique tool to explore dynamics in condensed matter, providing a microscopic description over a wide range of length scales according to the scattering vector Q, from the meso-scale at small angles to the atomic scale at wide angles. X-ray Photon Correlation Spectroscopy (XPCS) is an experimental technique to measure the intermediate scattering function f(Q,t) characterizing the dynamics of the sample. XPCS retrieves the f(Q,t) by quantifying the temporal correlation of the intensity fluctuations in coherent scattering patterns (speckles) that encode the electronic density fluctuations. Spontaneous and driven dynamics can be retrieved in the temporal domain down to 10-6 s in a large variety of soft and hard condensed matter systems, e.g. colloids, gels and phase-ordering alloys at the meso-scale, deeply super-cooled melts and structural glasses at the atomic scale.

The tutorial covers the fundamental principles of XPCS based on coherent X-ray scattering and details of the data collection. Special emphasis is put on the data analysis practice and interpretation of the results. Finally, we show the large impact for XPCS of 4th generation synchrotron radiation sources like the recent Extremely Brilliant Source at the ESRF, with the greatly increased brilliance and coherence enabling new exciting scientific opportunities in the field.

• This hands-on tutorial will introduce the capabilities of the new Nuclear Resonance beamline (ID14) at the ESRF with a special emphasis given on Mössbauer spectroscopy with the synchrotron Mössbauer source (SMS) at the nanoscale.

•  An introduction to data evaluation software and instructions on how to conduct an experiment at the beamline will be given.

Participants are encouraged to bring their own sample(s) for a test measurement in transmission geometry (57^Fe, sub-micron focused beam size in diameter).
