  1. 1. Nanoscale studies of the atmospheric corrosion of copper protected by ultrathin organic films

    Author : Weijie Zhao; C. Magnus Johnson; Christopher Leygraf; Guido Grundmeier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; corrosion inhibition; Langmuir-Blodgett LB deposition; self-assembly deposition; nano-FTIR; octadecylphosphonic acid ODPA .; Kemi; Chemistry;

    Abstract : Copper (Cu) has been utilised by humans for millenniums and has become an indispensable metal in modern industry and in our infrastructure. However, corrosion, as a natural process for metallic materials, takes place on copper surfaces in most environments. READ MORE

  2. 2. Oxygen sensing in Caenorhabditis elegans

    Author : Lina Zhao; Changchun Chen; Simon Tuck; Helena Edlund; Marc Pilon; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; acute hypoxia; G-protein; mitochondrial ROS; neuropeptide; GPCR;

    Abstract : Sufficient supply of oxygen (O2) to tissue is essential for survival of aerobicanimals. In mammals, there are constant homeostatic regulation mechanisms that act on different time scales to maintain optimal O2 delivery to tissues. The ability to detect and respond to acute oxygen shortages is indispensable to aerobic life. READ MORE

  3. 3. Synthesis of functionalized allylic, propargylic and allenylic compounds : Selective formation of C–B, C–C, C–CF3 and C-Si bonds

    Author : Tony Zhao; Kálmán Szabó; Hajime Ito; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium catalysis; allylboration; allenylboration; trifluoromethylation; silylation; copper catalysis; borylation; bimetallic catalysis; organisk kemi; Organic Chemistry;

    Abstract : This thesis is focused on the development of new palladium and copper- mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. The synthetic utility of the 1,2-diborylated butadienes synthesized in one of these processes has also been demonstrated. READ MORE

  4. 4. Pancreatitis-Associated Pulmonary Injury

    Author : Xia Zhao; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; inflammatory mediators; protein kinase C; leukocytes; acute lung injury; abdominal sepsis; acute pancreatitis; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : In acute pancreatitis (AP), lung injury is an early occuring and important part of the multiple organ dysfunction syndrome. The mechanisms underlying the development of lung injury though still largely remains unclear. READ MORE

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

    Author : Rong Zhao; KTH; []
    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.
