Molecular mechanism of a potent antibiotic produced by a sugarcane pathogen
26.04.2023
Albicidin is extremely potent bactericidal antibiotic active against problematic Gram-negative bacteria however its mechanism of action was not understood at the molecular level. Now, a collaborative research team of Polish, German and British scientists used cryo-electron microscopy facility at SOLARIS to determine structure of albicidin bound to the Escherichia coli DNA gyrase complexed with 217 double-stranded DNA fragment.

Surface and interface properties of TiO2/CuO thin film bilayers
12.04.2023
Thin films, particularly in a form of bilayer, are emerging as potential photocatalysts and photoelectrodes but the challenging aspect consists in the technology and investigation of the interface between both constituents. Thin film bilayers of TiO2/CuO were prepared by means of sequential reactive magnetron sputtering (Figure 1a) in Ultra-High Vacuum (UHV) system. It was demonstrated that under certain conditions both X-ray reflectivity XRR and optical reflectivity measurements can provide information concerning the interfacial properties. X-ray absorption spectroscopy XAS in the surface sensitive mode, i.e., Total Electron Yield TEY, was carried out at SOLARIS centre and allowed to draw conclusions concerning the oxidation state of copper and the electronic structure of the grown materials.

The first X-ray images recorded at POLYX beamline
13.03.2023
POLYX is a beamline under construction at SOLARIS that is focused on X-ray microimaging and microspectroscopy in the tender/hard energy range of 4-15 keV. A recent publication described the general concept of the beamline and showed first X-ray images measured at POLYX with a white (polychromatic) X-ray beam. Performed experiments demonstrated the possibility of X-ray phase contrast imaging of weakly absorbing test samples and focusing of the X-ray beam with polycapilllary optics for X-ray fluorescence imaging of elemental distribution inside samples.
