  1. 1. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hamish Keay; [2023]
    Nyckelord :Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Sammanfattning : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. LÄS MER

  3. 2. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Albin Olsson; [2022]
    Nyckelord :Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Sammanfattning : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. LÄS MER

  4. 3. Synthesis and characterization of half-sandwich complexes with salicylaldimine ligand derivatives

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ujala Mahmud; [2021]
    Nyckelord :Malaria; Plasmodium; Ruthenium; Iridium; Rhodium; Inorganic chemistry; Chemistry;

    Sammanfattning : New half-sandwich complexes of pentamethylcyclopentadienyl-rhodium, iridium, and p-cymene-ruthenium have been synthesized and characterized. All metal complexes contain ligands based on a 4-chloroquinoline framework analogous to the antimalarial drug chloroquine. LÄS MER

  5. 4. The Cumulative Benefits of Biochar in Agriculture

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Jawad; [2018]
    Nyckelord :biochar; climate; agriculture; livestock;

    Sammanfattning : Stockholm Exergi provide district heating in Stockholm and plan to integrate their district heating system with the production of biochar, by building a plant that produces 100MW district heating and 100 000 tonnes biochar per year, in order to reduce greenhouse gas emissions. Biochar may mitigate climate change, but the added benefits of biochar, beyond the benefits of carbon sequestration, lack quantification. LÄS MER

  7. 5. Study of Particle Production Mechanisms in PYTHIA 8 using Angular Correlations

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Joakim Alnefjord; [2017]
    Nyckelord :pythia; alice; particle; production; mechanisms; angular; correlations; Physics and Astronomy;

    Sammanfattning : An analysis of two-particle angular correlations was recently performed on measurements taken from pp collisions at $\sqrt{s}$ = 7 TeV by ALICE at the LHC. The correlations for mesons are in good agreement with simulations performed in Monte Carlo event generators such as PYTHIA and PHOJET, but there is a significant difference for baryons. LÄS MER
