  1. 1. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials

    University essay from KTH/Kemi

    Author : Clément Bouchut; [2024]
    Keywords : ligand; organic chemistry; organic synthesis; thermoelectric materials; thiol; ligand; organisk kemi; organisk syntes; termoelektriska material; tiol;

    Abstract : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. READ MORE

  2. 2. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

    University essay from KTH/Fysik

    Author : Serena Ambrosino; [2024]
    Keywords : Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

    Abstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

  3. 3. 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. 4. 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. 5. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Fredrik Petersson; [2023]
    Keywords : LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

    Abstract : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. READ MORE
