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

   Författare :Cu Dybelius Ansson; Lund Oftalmologi; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

   Författare :Tobias Törndahl; Jan-Otto Carlsson; Karin Larsson; Mikael Ottosson; Lauri Niinistö; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Atomic Layer Deposition; ALD; copper; copper I oxide; copper I nitride; deposition pathway; CuCl; Cu hfac 2; oxide substrates; epitaxy; DFT; ab-initio; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : Thin films play an important role in science and technology today. By combining different materials, properties for specific applications can be optimised. LÄS MER

4. 3. New Cu-I cluster compounds with luminescent properties

   Författare :Ehsan Jalilian; Sven Lidin; Torbjörn Gustafsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copper I iodide; structure determination; luminescence; TDDFT; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

   Sammanfattning : The aim of this thesis has been to investigate how the synthesis route, choice of solvent and counter-ions effects the crystallization of Cu(I)I systems, and to investigate the correlation between the structure and luminescence properties of the systems. In order to do so a series of compounds based on an anion containing Cu(I)I, stabilized by organic cations have been produced. LÄS MER

5. 4. Copper(I) Alkoxides and Aryloxides

   Författare :Cesar Lopes; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alkoxides; infrared; carbonyl; synthesis; crystal structure; triphenylphosphine; NMR; phenoxides; cryoscopy; aryloxides; Copper I ;

   Sammanfattning : Copper(I) alkoxides and aryloxides have been prepared from mesitylcopper(I) and alcohols or phenols. The solid state structures of the alkoxides and aryloxides are .my.2- and/or . LÄS MER

7. 5. Theoretical studies of blue copper proteins

   Författare :Mats H M Olsson; Beräkningskemi; []
   Nyckelord :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;

   Sammanfattning : 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.
