  1. 1. Investigation of an enzymatic cascade for the production of 5- hydroxymethylfurfurylamine

    University essay from KTH/Industriell bioteknologi

    Author : Sajitha Chandrakumaran; [2023]
    Keywords : Biocatalysis; Silicibacter pomeroyi; transaminase; enzymatic cascade; Cadaverine; Biokatalys; Silicibacter pomeroyi; transaminas; Enzymatisk kaskad; Kadaverin;

    Abstract : Biokatalys medför ett alternativt tillvägagångsätt för att kunna utforska och utveckla kemiskt syntetiserade vägar för produktionen av eftertraktade kemikalier, där hållbarhet och miljön tas till beaktan. I denna studie undersöktes potentialen av en enzymatisk kaskad för produktion av 5-hydroximetylfurfurylamin (HMFA). READ MORE

  3. 2. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Melker Axelsson; [2023]
    Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

  4. 3. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Aidas Urbonavicius; [2023]
    Keywords : ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Abstract : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. READ MORE

  5. 4. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mohamad Abd Elwadood; [2023]
    Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

  6. 5. Modelling the Water Table in a Bog

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Bowley; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.
