    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Juan Carlos Lopez Santiago; [2023]
    Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

  3. 2. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

    Master-uppsats,

    Författare :Christian Waldenberg; [2022-11-08]
    Nyckelord :Medical physics; Normoxic polymer gel dosimeter; NiPAM;

    Sammanfattning : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. LÄS MER

  4. 3. Phase behavior of mixtures of polyampholytic proteins and RNA: a toy model study

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Sammanfattning : Biomolecular condensates are aggregates formed from liquid-liquid phase separation through the interactions between nucleic acids and multivalent proteins. These condensates are essential for many biochemical processes inside the cell. LÄS MER

  5. 4. First principles DFT study of polyethylene insulation containing chemical impurities - implementing counterpoise correction

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Max Pierre; [2022]
    Nyckelord :Applied physics; HVDC cable; Polymer physics; Polyethylene; Density functional theory; Molecular dynamics; CP2K; GROMAC; Electron traps; Band gaps; Density of states; Tillämpad fysik; HVDC kabel; Polymerfysik; Polyeten; Täthetsfunktionalteori; Molekulärdynamik; CP2K; GROMACS; Elektronfällor; Bandgap; Tillståndstäthet;

    Sammanfattning : Density functional theory (DFT) calculations of polyethylene (PE) HVDC cable insulation have been performed for systems containing four different chemical impurities: acetophenone, cumene, $\alpha$-methyl styrene and $\alpha$-cumyl alcohol. Systems were generated by molecular dynamics (MD) equilibration at four different temperatures relevant for cable insulation applications: 277 K, 293 K, 343 K and 363 K. LÄS MER

  7. 5. Calculation of neutron scattering libraries for liquid ortho-deuterium and hydrogen deuteride

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Alexander Huusko; [2022]
    Nyckelord :PIMD; NJOY; HD; D2; HighNESS; ESS; RPMD; TSL; Physics and Astronomy;

    Sammanfattning : The European Spallation Source (ESS) has launched a project called HighNESS, with the task of investigating the potential of adding a second moderator system to the facility, with ortho-deuterium (o-D2) being the main material of interest. Another moderator material which could be of interest is hydrogen deuteride (HD). LÄS MER
