  1. 1. MATTER-ANTIMATTER INTERACTIONS The hydrogen-antihydrogen system and antiproton-matter interactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Stegeby; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimatter; antiproton; matter-antimatter interactions; hydrogen-antihydrogen system; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Abstract : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.

  2. 2. Particle-fluid interactions under heterogeneous reactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Thamali Rajika Jayawickrama; Kentaro Umeki; Henrik Ström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; drag coefficient; particle-laden flow; reacting flow; Energiteknik; Energy Engineering;

    Abstract : Particle-laden flows involve in many energy and industrial processes within a wide scale range. Solid fuel combustion and gasication, drying and catalytic cracking are some of the examples. It is vital to have a better understanding of the phenomena inside the reactors involving in particle-laden flows for process improvements and design.

  3. 3. Particle interactions at the nanoscale From colloidal processing to self-assembled arrays

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Bertrand Faure; Stockholms universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; materialkemi; Materials Chemistry;

    Abstract : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. READ MORE

  4. 4. Estimating Effective Interactions from Particle Trajectories

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Kolbjörn Tunström; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

    Abstract : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. READ MORE

  5. 5. Inverse Modeling of Cloud – Aerosol Interactions

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Daniel Partridge; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stratocumulus; marine; cloud; aerosol; interactions; MCMC; inverse modeling; droplet closure; global sensitivity; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : The role of aerosols and clouds is one of the largest sources of uncertainty in understanding climate change. The primary scientific goal of this thesis is to improve the understanding of cloud-aerosol interactions by applying inverse modeling using Markov Chain Monte Carlo (MCMC) simulation. READ MORE
