  2. 1. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

    Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

    Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

  4. 2. Water as a trace component in mantle pyroxene: Quantifying diffusion, storage capacity and variation with geological environment

    Author : Rickard Sundvall; Henrik Skogby; Alasdair Skelton; Eugen Libowitzky; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pyroxene; mantle mineralogy; water in nominally anhydrous minerals; iron redox-reaction; kinetics; water zonation; FTIR imaging; re-hydration capacity; Mineralogy; Mineralvetenskap; Mineralogy; Petrology and Geochemistry; mineralogi; petrologi och geokemi;

    Abstract : In this study, distribution and diffusion of water in pyroxene are examined in an effort to explain the water content variation observed in natural pyroxene. Water is a common trace component in many nominally anhydrous minerals (NAMs) from the Earth's crust and mantle and greatly impacts their physical properties. READ MORE

  5. 3. Hydrogen diffusion and storage mechanisms in diopside

    Author : Rickard Sundvall; Henrik Skogby; Alasdair Skelton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mineralogy; Mineralvetenskap; mineralogi; petrologi och geokemi; Mineralogy; Petrology and Geochemistry;

    Abstract : Hydrogen is a widespread trace element in many nominally anhydrous minerals (minerals without water or hydroxyl ions in their structural formula) from the Earth's crust and mantle. The hydrogen is normally incorporated in the form of hydroxyl ions and can be regarded as structurally bound water. READ MORE
