  1. 1. Nitro compounds for use in explosive charges

    Författare :Stefan Ek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This first part of this thesis describes synthesis of and characterisation of energetic plasticisers. The general concepts and requirements of energetic plasticisers are introduced. The remainder of this part further describes the work published in three publications. LÄS MER

  3. 2. Metal-Free O- and C-Arylation with Diaryliodonium Salts

    Författare :Erik Lindstedt; Berit Olofsson; Kilian Muñiz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine; Alkyl Aryl Ethers; Nitro Compounds; Alcohols; Diaryliodonium Salts; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis concerns the development of metal-free applications using diaryliodonium salts. The first project describes an arylation protocol of allylic and benzylic alcohols in aqueous media. The method proceeds under mild conditions and the ether products were obtained in moderate to good yields. LÄS MER

  4. 3. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air

    Författare :Hanna Söderström; Mats Tysklind; Per-Anders Bergqvist; Jochen F. Muller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; air pollution; alkyl-PAHs; atmosphere; bioavailability; boundary layer; diffusive sampling; emissions; integrative; membrane; monitoring; nitro-PAHs; PAHs; particles; passive samplers; PCBs; plants; PRCs; release rate; sampler design; sources; SPMDs; traffic; uptake rate; wind effect; wood burning; Miljökemi; Environmental chemistry; Miljökemi;

    Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER

  7. 5. In search of a biosensor for DNT detection : Studies of inducer response and specificity of DntR

    Författare :Rosa Lönneborg; Peter Brzezinski; Ray Dixon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DntR; transcriptional regulation; gfp; nitro-aromatic compounds; LysR family; LTTR; TNT; DNT; FACS; directed evolution; random mutagenesis; recombination; structure determination; biokemi; Biochemistry;

    Sammanfattning : The primary aim of the work presented in this thesis was to change the inducer specificity of the DntR protein in order to improve the response to DNT. The long-term goal is to use this protein in a biosensor for DNT, a signature compound for detection of the explosive TNT. LÄS MER
