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

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

    Författare :Hira Qazilbash; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  3. 2. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  4. 3. Production of 5-ketogluconic acid using recombinant strains of Gluconobacter oxydans

    Master-uppsats, Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

    Författare :Aakash Reddy Murugadasan; [2022]
    Nyckelord :Gluconobacter oxydans; Escherichia coli; 5-Keto-D-gluconic acid; Alcohol dehydrogenase; Biotechnology; Biology and Life Sciences;

    Sammanfattning : 5-Keto-D-gluconic acid (5-KGA) is a valuable compound that has a wide range of applications in the chemical and food industries and is commonly used as a precursor for manufacturing tartaric acid (TA). Industrial production of 5-KGA through chemical approaches was practiced in the early 1920’s and was dropped immediately due to several drawbacks because of its complicated process that resulted in lower 5-KGA yield and higher accumulation of impure gluconic acid.

  5. 4. Evaluation of the stability of immobilized lipases from Rhizomucor miehei and Rhizopus oryzae in high oleic sunflower oil

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Jinxu Xu; [2021]
    Nyckelord :lipase; immobilization; oxidation; biotechnology; Technology and Engineering;

    Sammanfattning : Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. LÄS MER

  7. 5. Algae hydrocarbons designed for bio-based lubricants

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Sjöhag; [2020]
    Nyckelord :Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

    Sammanfattning : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. LÄS MER
