  1. 21. 2-Hydroxypyridine-Ligated Pd-complexes as pre-catalysts in Hydrogen Borrowing Chemistry α -Alkylation of Ketones Using Alcohols

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ayesha Kanwal; [2017]
    Keywords : Hydrogen Borrowing in activation of alcohols; Palladium in Catalysis; hydrogenation and dehydrogenation reactions; hydrogen borrowing concept for hydrogenation and dehydrogenation reactions; 2-hydroxyquinoline Ligand; 2-hydroxy pyridine ligands; inorganic chemistry; oorganisk kemi; Chemistry;

    Abstract : An efficient method for selective alpha-alkylation of ketones with alcohols was developed using 2-hydroxypyridine-based ligands coordinated by palladium as pre-catalysts. The reactions were performed without additional additives under mild reaction conditions. The method is environmentally friendly to build C-C bond as water is the only byproduct. READ MORE

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Carolina Falkman; [2017]
    Keywords : bisfenol a; juvertumör; hund; bröstcancer; mekanismer;

    Abstract : Bisfenol A (BPA) är i vår miljö en ständigt närvarande organisk förening som används vid plastframställning. Vattendrag, hushållsdamm, elektronik och tuggleksaker av plast är bara en bråkdel av källorna där vi och våra husdjur utsätts för denna östrogenlika substans. READ MORE

  4. 23. Method Development for Determining the Stability of Heat Stable Proteins Combined with Biophysical Characterization of Human Calmodulin and the Disease Associated Variant D130G

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Ehlimana Aleckovic; Linnea Andersson; Sherley Chamoun; Ellen Einarsson; Ebba Ekstedt; Emma Eriksen; Maria Madan-Andersson; [2016]
    Keywords : Calmodulin; wild type; D130G variant; method; affinity; trifluoperazine; p-HTMI.;

    Abstract : Calmodulin is a highly conserved calcium ion binding protein expressed in all eukaryotic species. The 149 amino acid residues in the primary structure are organized in seven α helices with the highly flexible central α helix connecting the two non-cooperative domains of calmodulin. READ MORE

  5. 24. Microbial Fuel Cell for Waste Water Treatment

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Fabio Cameli; [2016]
    Keywords : Microbial Fuel Cell; Water treatment; Chemical Engineering; Electrochemistry; Energy sustainable process;

    Abstract : Microbial Fuel Cell is a novel technology that can be used for a waste water treatment in order to simultaneously remove carbonaceous matter and nitrogen while producing electrical power. Even if it is not an established technology so far, MFC could be a cost effective option for waste water treatment and the major challenge of this process will be the device scale-up. READ MORE

  6. 25. A simulation model of a reactor for ethylene oxide production

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hanna Perzon; [2015]
    Keywords : kemiteknik; chemical engineering; Chemistry;

    Abstract : This thesis has been performed in the ethylene oxide plant at Akzo Nobel in Stenungsund. Ethylene oxide is an important ethylene based intermediary compound. The primary use for ethylene oxide is in the manufacture of derivatives such as ethylene glycol, surfactants and ethanolamine’s. READ MORE
