  1. 1. The active phase of Pt(110) during catalytic CO oxidation

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Hira Qazilbash; [2024]
    Keywords : Physics and Astronomy;

    Abstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

  3. 2. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Arjun Monga; [2023]
    Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

  4. 3. Integrated membrane reactor for the production of butyl butyrate starting from biomass

    University essay from KTH/Fiber- och polymerteknologi

    Author : Carlos Rubio; [2023]
    Keywords : butyl butyrate; butanol; butyric acid; membrane technology; enzymatic catalysis; butylbutyrat; butanol; smörsyra; membrane teknologi; enzymatisk katalys;

    Abstract : Efterfrågan på energi ökar snabbt, och denna trend förväntas bestå. Det råder dock ingen tvekan om att världen för närvarande befinner sig i en energikris, som är en katastrof både ekonomiskt och miljömässigt. Följaktligen är sökandet efter alternativa energikällor för att ersätta fossila bränslen absolut nödvändigt. READ MORE

  5. 4. Aromatic Ring Flips and Local Volume Fluctuations in BPTI

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Simon Enbom; [2022]
    Keywords : Biophysical Chemistry; Molecular Dynamics; Protein Dynamics; Activation Volume; Aromatic Ring Flips; BPTI; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Aromatic ring flips are a classic example of a dynamic process in proteins. Discovered decades ago, methodological limitations hindered progress at the time. Ring flips have gained new interest and experimentalists can measure the flip rate and thermodynamic quantities associated with it. READ MORE

  6. 5. Catalytic synthesis of benign bisphenols

    University essay from KTH/Kemi

    Author : Victoria Chu; Emma Lundqvist; Hampus Hagelin; [2022]
    Keywords : Bisphenols; Vanillyl alcohol; Friedel-Crafts alkylation; Lewis acid catalysis; Sustainability; Bisfenoler; Vanillylalkohol; Friedel-Crafts alkylering; Lewissyra-katalys; Hållbarhet;

    Abstract : This study analyzes the reactivity and selectivity of Friedel-Crafts alkylations using benzylic alcohols and phenols in the presence of a Lewis acid, to synthesize methoxylated bisphenols as a benign alternative to BPA. The degree of methoxylation on the electrophile appears to affect the yield of the reaction while the degree of methoxylation on the nucleophile appears to affect the selectivity. READ MORE
