  2. 11. Creating and Probing Extreme States of Materials : From Gases and Clusters to Biosamples and Solids

    Author : Bianca Iwan; Nicusor Timneanu; Janos Hajdu; Stacey Sorensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-electron laser; ultrashort X-rays; non-equilibrium plasma; Coulomb explosion; isotope effect; hydrodynamic expansion; ion acceleration; high intensity lasers; ablation; time-of-flight spectroscopy; Fysik; Physics;

    Abstract : Free-electron lasers provide high intensity pulses with femtosecond duration and are ideal tools in the investigation of ultrafast processes in materials. Illumination of any material with such pulses creates extreme conditions that drive the sample far from equilibrium and rapidly convert it into high temperature plasma. READ MORE

  4. 12. Charge and proton dynamics in molecules and free clusters : from atomic to nanometer scale

    Author : Bart Oostenrijk; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charge transfer; Electron-Ion coincidence; proton hopping; Coulomb explosion; Cluster fission; site-selective dissociation; Molecular photodissociation; spectroscopy; Fysicumarkivet A:2018:Oostenrijk;

    Abstract : The origin of properties in complex systems can often be traced to mechanisms involving charge and energy transfer in only a few embedded molecules. The detailed study of the time evolution of these mechanisms in their original environment is a challenging task. READ MORE

  5. 13. Th Dynamics of Star Cluster Formation

    Author : Juan Pablo Farias Osses; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Star Formation; Star Clusters; Stellar Dynamics;

    Abstract : A major question in astrophysics is how star clusters form. These objects are important, since they are the birth sites of most stars, perhaps including our own Sun. READ MORE

  6. 14. On error controlled atomistic-to-continuum modeling with application to graphene monolayers

    Author : Arash Memarnahavandi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quasi-Continuum; stress-free; atomistic-to-continuum; homogenization; adaptivity;

    Abstract : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. READ MORE

  7. 15. From a Road Less Travelled to a Worn Path: Three-Dimensional Tumour Models for Cancer Research and Therapeutics

    Author : Atena Malakpour Permlid; NanoLund: Centre for Nanoscience; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D tumour models; scaffold-based cultures; cancer cells; electrospun scaffolds; extracellular matrix; tumour microenvironment; high-throughput screening; animal-free; donor herd horse serum; fibroblasts;

    Abstract : Cancer is the second leading cause of death among both men and women worldwide. During therecent years, three-dimensional (3D) tumour models have gained increasing interest as a pre-clinicalplatform for screening of compounds for potential use in cancer therapy. READ MORE
