  2. 1. 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.

  4. 2. Nucleator-driven assembly of curli organelles and their pathophysiological role in E. coli septic shock

    Author : Zhao Bian; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Assembly; Curli; NOS2; Nucleator; Sepsis;

    Abstract : The understanding of how polymeric surface structures are assembled in bacteria is one of general interests, which can provide insight into details of macromolecule interactions, and study how proteins fold into domains as assembly modules for building organelles. Protein-protein interactions in various subcellular compartments lead to the assembly of fimbriae at bacterial cell surfaces. READ MORE

  5. 3. Advanced MEMS Technology for Terahertz Frequencies

    Author : Zhao Xinghai; Joachim Oberhammer; Umer Shah; Oleksandr Glubokov; Jan Stake; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the development of terahertz (THz) technology, a variety of application demands are growing rapidly, such as high-rate communications, THz radars, environmental monitoring, medical imaging, and space exploration. However, the fabrication, integration, and packaging techniques for THz components and systems pose great challenges for a large-scale, cost-effective production. READ MORE

  6. 4. Theoretical Studies of Diamond for Electronic Applications

    Author : Shuainan Zhao; Karin Larsson; Mats Boman; Gueorgui Gueorguiev; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diamond; Surface functionalization; Electronic structure; graphene; dopant; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Diamond has since many years been applied in electronic fields due to its extraordinary properties. Substitutional dopants and surface functionalization have also been introduced in order to improve the electrochemical properties. READ MORE

  7. 5. 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
