POSTPONED TO 2021

The XiBiGP 2020 workshop is postponed to 2021, due to the coronavirus pandemic and the unforeseeable possibilities of most of our speakers to participate the conference.

X-ray and VUV Interaction with Biomolecules in Gas Phase (XiBiGP) Workshop

The 4th workshop on X-ray and VUV Interaction with Biomolecules in Gas Phase – XiBiGP will be co-organized with the Synchrotron SOLEIL (France) in the frame of the 30th Summer School and International Symposium on the Physics of Ionized Gases (SPIG). The XiBiGP workshop is principally related (but not exclusively) to the Section 1 of the SPIG topics.

There has been a large interest to study biological systems by using synchrotron-based spectroscopic techniques, such as Photon electron spectroscopy (PES), Photoelectron photoion coincidence spectroscopy (PEPICO), Near-edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron (XPS), X-ray emission spectroscopies etc. Particularly, gas-phase spectroscopy gives the opportunity to investigate isolated targets, under well-defined conditions. However, there has been always a challenge both to bring a large biomolecule intact into the gas phase and to obtain a high-enough sensitivity for a fine structure (and even coincidence) spectroscopy of desired species in a diluted environment. It is even more challenging to investigate solvation effects under well-defined conditions.

The aim of the XiBiGP workshop is to present the most recent cutting-edge techniques used to investigate X-ray and VUV interaction with biomolecules in gas phase. The workshop is dominantly dedicated to young scientists, but also to all SPIG participants who might find interesting possibilities and topics regarding the multidisciplinary studies and developments of new experimental techniques. Finally, the aim of the workshop is to initiate a discussion between experts in the field on X-ray and VUV spectroscopy that could lead to further improvement of the techniques and important results.

The 4th XiBiGP workshop will be dedicated to PES and PEPICO investigation of small biologically relevant molecules isolated in the gas phase, bio-functionalized nanoparticles and clusters, biomolecules in liquids (in vacuo liquid jet spectroscopy) and action spectroscopy of macromolecular ions.
