Material Research Lab and NOMATEN Centre of Excellence study and test, among other things, structural materials and their combinations, using modern, specialised analysis equipment. The laboratories’ research infrastructure now includes a recently launched transmission electron microscope. ----

Galactic outflows drive the evolution of dwarf galaxies

Fig. 1: Artist’s illustration of galactic outflows. Star-formation activity can produce powerful winds (outflows) that could possibly carry the gas at very large distances, out in the intergalactic medium. The broad wings in the spectra of[CII] 158 μm lines are a clear signature of outflowing atomic gas. Credit: ESA/Hubble, ESO/L. Calçada, M. Romano.
Stellar feedback is expected to play a key role in regulating the evolution of low-mass galaxies by producing galactic-scale winds (also known as outflows) that push the gas away from the interstellar medium, eventually preventing from the formation of new stars. In this respect, an international team of astronomers led by NCBJ scientist, have published a work on the Astronomy & Astrophysics journal addressing the impact of galactic outflows on the baryonic cycle of nearby dwarf galaxies. ----

Machine learning helps understand the behavior of magnesium alloys

Machine learning was used to map the distribution of dislocations in Mg alloys and predict their mechanical properties. A group of scientists from Finland, Spain, and NCBJ trained a deep learning model on a dataset of electron backscatter diffraction (EBSD) images of Mg alloys with different dislocation densities. This could lead to the development of novel materials with optimized mechanical properties. Their paper appeared in the July issue of Nature Scientific Reports. ----

NCBJ is building a station generating an ultra-high dose electron beam (FLASH)

At the NCBJ Nuclear Equipment Department, with the participation of the NCBJ Nuclear Equipment and Techniques Department, the accelerator structure for the new FLASH therapy research station was designed and built. The pioneer stand is to use the construction of the AQURE medical accelerator and is ultimately to operate at the WCO in Poznań. ----
