  1. 1. Redox models in chemistry  A depiction of the conceptions held by secondary school students of redox reactions

    University dissertation from Umeå : Kemiska institutionen. Umeå universitet

    Author : Lise-Lotte Österlund; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; science education; redox reaction; model; inorganic chemistry; organic chemistry; biochemistry; students conceptions; textbook; NATURAL SCIENCES Chemistry Other chemistry; NATURVETENSKAP Kemi Övrig kemi; didactics of chemistry; kemididaktik;

    Abstract : According to previous research, students show difficulties in learning redox reactions. By the historical development different redox models exist to explain redox reactions, the oxygen model, the hydrogen model, the electron model and the oxidation number model. READ MORE

  2. 2. Spectroelectrochemistry of Redox Enzymes

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Andreas Christenson; Lunds universitet.; Lund University.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; complex II; bilirubin oxidase; laccase; enzyme mechanism; redox potential; electron transfer; spectroelectrochemistry; redox enzymes; Spectroelectrochemical cell;

    Abstract : Popular Abstract in Swedish Det ljus (fotonflöde) som solen sänder ut är grunden för biologiskt liv. Med denna strålning överförs en del av den frigjorda energin från solen till jordens biosfär, där växterna tar upp de energirika fotonerna och omvandlar fotonenergin till kemisk energi. READ MORE

  3. 3. Thiyl radicals, reaction kinetics and redox chemistry

    University dissertation from Stockholm : Kemi

    Author : Rong Zhao; KTH.; [1998]
    Keywords : ;

    Abstract : In focusing on the free radical chemistry of thiyl radicals,two importantclasses are dealt with, namely, the amino acidalkylthiyl and the acylthiyl radicals, where pulse radiolysisand steady state γ-radiolysis are applied.Amino acid thiyl radicals (RS•), are important in manybiological systems,as intermediates in the repair reactions ofthiols towards targeted carbon-centeredradicals and ascatalytic centers in many enzymatic reactions.

    Abstract : Organic electrode materials represent an intriguing alternative to their inorganic counterparts due to their sustainable and environmental-friendly properties. Their plastic character allows for the realization of light-weight, versatile and disposable devices for energy storage. READ MORE

  5. 5. Reaction mechanism of metalloenzymes studied by theoretical methods

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Theoretical Chemistry

    Author : Geng Dong; Lunds universitet.; Lund University.; [2018-05]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metalloenzymes; Reaction mechanism; QM MM; DFT; DMRG; CAS-srDFT; Big-QM; QTCP;

    Abstract : Metalloenzymes are proteins that contain one or more metal ions bound to protein. They constitute about one-third of all enzymes known so far and they often perform hard chemical reactions involving small substrates, like H2 and N2. In our research, we focus on those metal ions that are located in the active sites and perform redox reactions, i.e. READ MORE
