NOMATEN HYBRID-SEMINAR, MARCH 19th, Microstructure stability of compositionally complex materials under extreme environment: Predictive modelling and experimental validation
Microstructural stability of multi-component systems under extreme environment represents one of most challenging issues not only in multi-scale materials modelling but also for developing reliable and advanced engineering components for nuclear material applications. Recently, compositionally complex alloys (CCAs) are designed as novel radiation-resistant materials for future fusion power plants while...
NOMATEN ONLINE-SEMINAR March 5: Click and bioorthogonal chemistries for health
The development of chemical reactions that can be performed in living systems (i.e. cells, model organisms) has long held unique fascination in the field of chemical biology. A bio-orthogonal reaction is characterized by the reaction of two functionalities, which will react under mild physiological conditions and are inert towards the biological environment.
NOMATEN ONLINE-SEMINAR February 20: Efficient discovery of ultra-strong high-entropy alloys by mechanistic theory of yield strength
Body-centered-cubic (BCC) high entropy alloys show exceptional strengths up to 1900K [1]. Fundamental understanding of the mechanisms that control strengthening is necessary to formulate a theory that enables screening over the immense compositional HEA space [2]. Supported by experimental findings in NbTaTiV and CrMoNbV alloys [3], we show with theory [4] that edge dislocations can
NOMATEN ONLINE-SEMINAR February 6: How to model microstructure in FeCr under and out of irradiation: a phase field approach
Faced with major societal challenges (ecological crisis, energy crisis), it is essential to better understand the behaviour of materials in order to improve the lifespan of nuclear reactors as well as their safety. The properties of materials are...
NOMATEN HYBRID-SEMINAR, JANUARY 9th, The application of flow cells and computational fluid dynamics for improved corrosion and electrochemical analysis
Hydrodynamics can play a critical role in the degradation of materials, often defining the rates and mechanisms by which metals corrode. To improve the understanding of the relationship between fluid flow and corrosion, precise and well characterised experimental techniques are required. The application...
NOMATEN HYBRID-SEMINAR, DECEMBER 19th, Atom Probe Tomography Studies of Nuclear Materials
Atom probe tomography (APT) is a unique analysis technique providing chemical analysis with near atomic resolution in 3D. Here, recent APT research on nuclear materials performed at Chalmers University will be presented. Zirconium alloys are used as fuel claddings in nuclear reactors and undergo degradation due to corrosion, hydrogen pick-up and irradiation damage. Using APT...
NOMATEN ONLINE-SEMINAR December 5: Structural and functional diversity of venom toxins interacting with GPCRs
Peptide toxins from venoms have undergone a long evolutionary process allowing host defense or prey capture and making them highly selective and potent for their target. This has resulted in the emergence of a large panel of toxins from a wide diversity of species, with varied structures and multiple associated biological functions. In this way...
NOMATEN HYBRID-SEMINAR, NOVEMBER 21st, Phase-field modelling of microstructure evolution in displacive transformations
Displacive transformations, like deformation twinning or martensitic transformation, are associated with microstructure evolution, which involves nucleation, propagation and annihilation of interfaces. For instance, the functional properties...
NOMATEN ONLINE-SEMINAR November 7: Laser and Optical Methods and their Development for Modern Innovative Technological Applications: from Civil Nuclear to Historical and Cultural Art Heritage
Modern science and technologies and their rapid intensive development are in search for innovative efficient methods in a wide range of their applications. Laser and optical methods may offer a numbers of attractive features, such as being contactless, remote, non-destructive, real time and in situ applicable. LANIE laboratory...
NOMATEN HYBRID-SEMINAR, NOVEMBER 2nd, Alpha-decay damage in natural apatite: buildup and recovery mechanisms for thermochronological applications
Thermochronology is an earth science discipline involved in the reconstruction and timing of past geological processes. In this field, rock accessory minerals such as apatite are collected and their thermal histories (temperature vs. time) reconstructed to study landscape evolution and mountain-building processes. One of the low-temperature techniques...
