Vacancy clusters have a major contribution in multiple mechanisms as oxidation, precipitation and creep and can lead to material premature cracking. It is thus essential to have a deep understanding of the stability of these defects under a wide range of stress and temperature. Multiple factors...

We have performed density functional/molecular dynamics (DF/MD) simulations to investigate the drift of Ag atoms in an amorphous GeS2 solid-state electrolyte between Ag and Pt electrodes in the presence of a finite electric field [1]. The atomistic model structure represents a conductive bridging random access memory (CBRAM) device, where the electric field...

The NOMATEN Innovation Days aimed at engaging in a dialogue with industry representatives and understanding their needs concerning collaborative projects with the scientific sector. The conference featured panels and inspiring lectures promoting research and development cooperation, as well as sessions related to material research in various applications, such as the chemical, energy, automotive, and metallurgical industries, among other areas of expertise, including industrial radiography and nuclear techniques for engineering applications.

When layers of two-dimensional (2D) materials are stacked on top of each with a relative twist, the resulting reconstruction pattern ("moiré pattern") dominates the electronic behavior. Depending on the twist angle, the moiré scale can be several orders of magnitude larger than the scale of the underlying atomic lattices, and the lead to emergent behavior, including superconductivity. This field of physics in 2D materials...

New research program in AI - IDEAS NCBR – has been launched. This center will become a discussion platform between academia and business. It aims at providing a high-quality working environment by creating interesting employment conditions and leading mentoring program. IDEAS NCBR supports researchers to...

For nearly twenty years now, the academic – and increasingly industrial – world has been interested in new classes of metallic alloys. HEA (high entropy alloys), which are concentrated, single-phase alloys based on several metallic elements and whose Cantor alloy (Co20Cr20Fe20Mn20Ni20) is the archetype, were quickly supplemented by multiphase alloys, CCA (complex concentrated alloys) or MPEA (multi principal elements alloys) in which secondary phases bring improvements in properties.

Atom Probe Tomography (APT) enables access to compositional, morphological and structural information from microstructural features at the atomic scale. This information is especially important on neutron-irradiated material to characterize chemical composition variations around...

In the context of fast neutron reactors, boron carbide is a ceramic material with excellent properties for controlling nuclear reactor power. Thanks to its high absorption cross sections of 10B, this material provides an excellent neutron absorber. As a consequence of the 10B(n,α) nuclear reactions, significant quantities...

Synchrotron X-rays provide ideal tools for studying the processes that control localised corrosion of metals in wet environments, which is key to understanding the processes that can cause damage to structures such as nuclear waste storage containers and aircraft.  In this talk, the morphology of localised corrosion is...
