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

    University dissertation from Umeå : Umeå University

    Author : Raja Subramaniam; Calle Nilsson; Paula Vanninen; [2012]
    Keywords : 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;

    Abstract : 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. Quantum Chemical Modelling of Biomimetic Phosphoesterase Complexes

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Henrik Daver; Fahmi Himo; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Phosphoesterases are a class of enzymes that catalyze hydrolysis of phosphoester bonds. They facilitate the modification of nucleic acid sequences, as well as the breakdown of rest products of warfare agents and insecticides. In this thesis, three biomimetic complexes that perform the same tasks are studied using density functional theory. READ MORE

  3. 3. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

    University dissertation from Department of Physics, Lund University

    Author : Tripta Kamra; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. READ MORE

  4. 4. New applications and developments of field-asymmetric ion mobility spectrometry - mass spectrometry (FAIMS-MS)

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Axel Mie; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; triazine; enantiomer; ion focusing; ion mobility; FAIMS; DMS; axial ion inlet;

    Abstract : Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. READ MORE

  5. 5. Computational Modeling of the Mechanisms and Selectivity of Organophosphate Hydrolases

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Miha Purg; Shina C. Lynn Kamerlin; Iñaki Tuñón; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organophosphate Hydrolase; Computational enzymology; MPH; DFPase; PON1; Empirical Valence Bond; EVB;

    Abstract : Computational modeling is becoming an increasingly integral part of (bio)chemistry, providing a powerful complementary view into the dynamics, binding, and reactivity of biochemical systems. In particular, molecular simulations based on multiscale models are now regularly employed in studies of enzymatic reactions, offering invaluable mechanistic insight through the lens of molecular energy landscapes.
