Effective and environmentally friendly removal of pharmaceuticals from wastewater under visible light
27.06.2024
The research team working under the leadership of Prof. Anna Zielińska-Jurek from the Faculty of Chemistry at Gdańsk University of Technology, in cooperation with scientists from ASTRA beamline, developed and characterized a new semiconductor material based on bismuth orthovanadate (BiVO4) and copper oxide sub-nanoclusters (CuOx). This material, when exposed to visible light, is able to effectively remove pharmaceuticals in water. Measurements made at the SOLARIS synchrotron using X-ray absorption spectroscopy (XAS) revealed the oxidation state of copper oxides. The research results were published in the journal "Separation and Purification Technology" from Elsevier publisher.

Calculate the orientation of macromolecules in three-dimensional space
07.06.2024
Scientists from the CIRI beamline are developing a method to calculate the orientation of macromolecules in three-dimensional space based on microscopic measurements using mid-infrared light polarized linearly at different angles. Reconstructing the experimental shape of the absorption dependency on polarization by fitting a nonlinear function to the data points obtained from the measurements allows for determining the angles that define the orientation of macromolecules in three-dimensional space, as well as a parameter describing the degree of sample organization. The measurements were conducted using an FPA array detector available at the FT-IR microscopy end-station on the CIRI beamline.

Strain-control over the valley degree of freedom
16.05.2024
Department of the Ecole Normale Supérieure Paris, France in collaboration with scientists from URANOS SOLARIS Centre have published in Physical Review Letters the results of their research on the Valley-Polarized Quantum Hall Phase Dirac System. The different local band minima – called valleys – of a multivalley 2D topological insulator have been independently characterized using ARPES experiments. An efficient control over their electronic population using mechanical strain has been demonstrated.

The relationship between the structure of polyurethane frameworks and the structural and superconducting properties of Y-123 foams
16.04.2024
A Polish team of researchers led by Dr. Paweł Pęczkowski from the Institute of Physical Sciences, Faculty of Mathematics and Natural Sciences, Cardinal Stefan Wyszyński University used the PIRX beam to study the properties of the electronic structure of superconducting foams obtained on the basis of polyurethane foams. The research results were published in the Journal of the European Ceramic Society published by Elsevier.
