A team of researchers from the Universitat Politècnica de Catalunya (Spain), Universidade Estadual de Campinas (Brazil) and Stanford University (USA) performed advanced quantum atomistic simulations to assess the Bose-Einstein condensate fraction of solid helium at zero temperature containing dislocations, a defective system that previously had been proposed to be “supersolid”

The researchers Siddharth Pitta, Jose I. Rojas, Francesc Roure, Daniel Crespo, and Magd Abdel Wahab, from the Group of Materials Characterization of the UPC, the Materials Strength Laboratory of the UPC, and the Ghent University, have made new progresses in the characterization of the fatigue response of aircraft repair patches made of carbon fiber reinforced epoxy (CFRE) and aluminum alloy on aircraft airframe substrates made as well of CFRE and aluminum alloy

Researchers Y. J. Duan, E. Pineda and D. Crespo, from the Group of Materials Characterization of the UPC, have made new progress to understand the mechanical properties of high-entropy metallic glasses. The work clarifies the correlation between the fraction of liquid-like zones, i.e. the fraction of atoms that can easily rearrange under the effect of external forces, and the secondary or β relaxation observed in these materials. Besides, the work reveals the high-entropy effect on the supercooled liquid dynamics of the metallic melt.

Nikolai Kvashin defended his thesis co-directed by Napoleón Anento and Dmitry Terentyev on 16th of November 2022 at Campus Nord. Titled “Atomistic Study of Slip Transfer in BCC Metals “, the thesis presents an atomistic computer simulation study on the interaction between dislocations (single and pile-up cases) and a set of grain boundaries with the purpose to investigate the role played by the grain boundary atomic structure
