Can the latest achievements of machine learning (ML) and artificial intelligence (AI) pave a fundamentally new way of doing science? How to teach the algorithm a proper analysis of the huge amounts of data, highlighting anomalies and detecting patterns that humans could never have spotted?

Dr Kazimierz Skrobas from our Institute, the Laboratory of Nanomaterials, will introduce the data processing technique called Machine Learning (ML) and show his material science research examples that employ AI. He will present an application of two simple ML algorithms called Decision Tree and Random Forest to X-ray diffraction data processing will be shown. X-ray diffraction is a basic tool for crystal structure characterization but in many cases analysis is not trivial and extraction of full information is cumbersome. This is true especially for nanostructures where crystal size, crystal shape, and deviation of the atomic structure from perfect periodicity are of particular interest.

The Seminar “Application of Machine Learning to material science domain” will be held on Thursday, March 23, 2023 at 15:30* on Zoom platform. To get the link to join the seminar, please contact us at dyrekcja@unipress.waw.pl

*note that the seminar will start at 15:30, that is 30 min later than usually.

VIIth Winter Workshop Kalatówki 2023 on Physics and Applications of Nitride Semiconductors will be organized on March 26-31, 2023 in Zakopane (Poland). The workshop will gather the researchers from the Institute of High Pressure Physics Polish Academy of Sciences and from the collaborating scientific institutes.

The Winter Workshop Kalatówki has been serving as a platform for exchanging information and ideas between the laboratories of the Institute of High Pressure Physics for years. Scientific subjects covered include physics and technology of quantum structures of AlInGaN semiconductors, mainly in the context of light emitters. Nitride-based electronics and crystal growth physics is also in focus.

This year, the invited guests of the VIIth Winter Workshop Kalatówki 2023 will be Prof. Enrique Calleja (University of Madrid) and Prof. Tomasz Czyszanowski (Lodz University of Technology).

Explaining and describing previtreous dynamics is one of the challenges of the 21st century. So far, the proposed theories and relationships that scale viscosity or relaxation time on cooling have not been widely accepted for experimental verification. A broader and more comprahensive approach to these problems is presented by a team of researchers from our Institute, the X-PressMatter Laboratory: Aleksandra Drozd-Rzoska, Sylwester J. Rzoska and Szymon Starzonek. Their work "New scaling paradigm for dynamics in glass-forming systems", will soon be published in the prestigious journal Progress in Materials Science (IF=48.165) https://doi.org/10.1016/j.pmatsci.2023.101074
