  1. 1. Simplified Routines for Sample Preparation and Analysis of Chemical Warfare Agent Degradation Products

    Författare :Raja Subramaniam; Calle Nilsson; Paula Vanninen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nerve agents; Alkyl alkylphosphonic acids; Solid phase derivatization; Fluorinated diazomethane reagent; High-energy collision induced dissociation; CID MS MS library; analytisk kemi; Analytical Chemistry;

    Sammanfattning : The thesis describes the development of new and improved methods for analyzing degradation markers from organophosphorus Chemical Warfare Agents (CWAs). Paper I and II describes an innovative and significantly improved method for the enrichment, derivatization (trimethysilylation) and GC-MS analysis of a broad range of organophosphorus CWAs degradation markers, namely the alkylphosphonic acids and a zwitterionic compound.

  2. 2. Exploring different thermoplastics from lignocellulosic building blocks and monomers

    Författare :Olivier Bonjour; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

    Sammanfattning : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. LÄS MER

  3. 3. Advanced polymeric scaffolds for functional materials in biomedical applications

    Författare :Kim Öberg Hed; Michael Malkoch; Eric Drockenmuller; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; hydrogel; PEG; dendritic monolayers; thiol-ene networks; off-stochiometric;

    Sammanfattning : Advancements in the biomedical field are driven by the design of novel materials with controlled physical and bio-interactive properties. To develop such materials, researchers rely on the use of highly efficient reactions for the assembly of advanced polymeric scaffolds that meet the demands of a functional biomaterial. LÄS MER

  4. 4. Simulation of Core-Level Spectra of H-bonded Systems

    Författare :Iurii Zhovtobriukh; Lars G.M. Pettersson; Anders Nilsson; Marcus Lundberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; x-ray absorption; non-resonant x-ray emission; damped linear response theory; time-dependent density functional theory; semi-classical approximation to Kramers-Heisenberg formula; Reverse Monte-Carlo; kemisk fysik; Chemical Physics;

    Sammanfattning : The thesis consists of three related projects where attempts have been made to simulate X-Ray Absorption (XAS) spectra of water and hexagonal ice, static non-resonant X-ray Emission (XES) spectrum of water and to apply the semi-classical approximation to Kramers-Heisenberg formula (SCKH) formalism to calculate the non-resonant XES spectrum of water and methanol. The first project is devoted to an investigation of the performance of damped response theory in combination with the DFT electronic structure method (CPP-DFT) in XAS spectrum simulations of liquid water.

  5. 5. Synthesis of a targeted library and thrombin inhibitors using organometallic chemistry

    Författare :Fredrik Thorstensson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of organometallic chemistry in the pursuit of novel scaffolds is outline d. A 4-phenyl- 2-carboxy-piperazine targeted combinatorial chemistry library has been synthesized aimed at the early lead discovery phase. LÄS MER
