2. 1. Fundamental in-situ and ex-situ studies of energy storage related materials including different applications of voltammetry

   Author : Ulrik Palmqvist; Patrice Millet; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ni-Cd pocket plate batteries; b-Ni OH 2; b-NiOOH; failures; goethite; surface complexation; Pb II ; Zn II ; Cu II ; Cd II ; in-situ; carbon; nanostructured; voltammetry; X-ray diffraction; electrical test; potentiometry; TEM; chlorination; oorganisk kemi; Inorganic Chemistry;

   Abstract : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. READ MORE

4. 2. Perfusion Monitoring of Advancement and Rotational Flaps. Oculoplastic Surgery and Laser Speckle Contrast Imaging

   Author : Cu Dybelius Ansson; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; flap; eyelid; oculoplastic; diathermic coagulation; laser speckle contrast imaging; perfusion; flap; eyelid; oculoplastic; diathermic coagulation; laser speckle contrast imaging;

   Abstract : Flaps are widely used in oculoplastic reconstructive surgery to cover defects following the removal of tumors, malformations, or trauma. Adequate blood perfusion of the flap is crucial for its survival. Knowledge about the perfusion in different type of flaps is therefore of great value. READ MORE

5. 3. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage

   Author : Jörgen Jönsson; Lars Lövgren; Per Persson; Staffan Sjöberg; Douglas B Kent; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; schwertmannite; goethite; lepidocrocite; acid mine drainage; sulphate; natural organic matter; mineral surface; infrared spectroscopy; EXAFS; XRD; ternary surface complex; copper II ; cadmium II ; lead II ; zinc II ; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. READ MORE

6. 4. Theoretical studies of blue copper proteins

   Author : Mats H M Olsson; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; metal-thiolate bonds; axial ligation; electron transfer proteins; reduction potential; reorganisation energy; Cu II ; Cu I ; strain; Induced-rack theory; Entatic state theory; cytochrome c oxidase; CuA; nitrite reductase; azurin; Blue copper proteins; plastocyanin; B3LYP; CASPT2; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

   Abstract : In this thesis, a critical investigation is presented about the role of mechanical strain for the electron-transfer properties of the blue copper proteins. It has been found that the structure of a realistic model complex of the oxidised blue-copper active site, optimised in vacuum with the B3LYP method, has the same trigonal cupric geometry as in the protein.

7. 5. Refined crystal structures of Zn(II)- and Cu(II)-alcohol dehydrogenase : a comparative study

   Author : Salam al-Karadaghi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

   Abstract : The crystal structure of the ternary complex of horse liver alcohol dehydrogenase (LADH) with the coenzyme NADH and inhibitor dimethyl sulphoxide (DMSO) (space group PI) has been refined by simulated annealing with molecular dynamics and restrained positional refinement using the program system XPLOR. The resulting crystallographic R- factor is 17. READ MORE
