  1. 1. Modeling framework for ageing of low alloy steel

    Author : Magnus Boåsen; Pål Efsing; Jonas Faleskog; Carl F. O. Dahlberg; Christian Niordson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloy steel; length scale effects; size effects; plasticity; cleavage fracture; brittle fracture; weakest link; ageing; weld metal; Hållfasthetslära; Solid Mechanics;

    Abstract : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. READ MORE

  2. 2. Efficient and Reliable Simulation of Quantum Molecular Dynamics

    Author : Katharina Kormann; Sverker Holmgren; Gunilla Kreiss; Hans O. Karlsson; Christian Lubich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-dependent Schrödinger equation; quantum optimal control; exponential integrators; spectral elements; radial basis functions; global error control and adaptivity; high-performance computing implementation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The time-dependent Schrödinger equation (TDSE) models the quantum nature of molecular processes.  Numerical simulations based on the TDSE help in understanding and predicting the outcome of chemical reactions. READ MORE

  3. 3. Homology and machine learning for materials informatics

    Author : Bart Olsthoorn; Jens H. Bardarson; Alexander V. Balatsky; O. Anatole von Lilienfeld; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; Teoretisk fysik;

    Abstract : Materials informatics is the field of study where materials science is combined with modern data science. This data-driven approach is powered by the growing availability of computational power and storage capability. READ MORE

  4. 4. Thermal Properties of Clusters and Molecules - Experiments on Evaporation, Thermionic Emission, and Radiative Cooling

    Author : Erika Sundén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water clusters fullerenes unimolecular decay evaporation thermionic emission radiative decay cooling rates heat capacities;

    Abstract : This thesis presents experiments performed on clusters and molecules, where the three channels of unimolecular decay have been studied. Evaporation from protonated and negatively charged water cluster have yielded size dependent heat capacities, where the smallest sizes with fewer than $21$ molecules show a heat capacity similar to bulk ice whereas clusters with molecules between $21$ and $300$ have a heat capacity in between that of ice and liquid water.
