    Abstract : The oak wood of the 17th century warship Vasa has shown significant changes in the chemical and mechanical properties as compared to recent oak. The most important factors contributing to these changes are the incorporation of iron compounds during waterlogging and the uptake of polyethylene glycol (PEG) in the course of the preservation treatment.

  3. 3. Development of Enhanced Analytical Methodology in Pesticide Chemistry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tuija Pihlström; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties.

    Abstract : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.

  5. 5. Development of Ultra-fast Biosensors for Detection of Non-electroactive Neurotransmitters

    University dissertation from Chalmers University of Technology

    Author : Yuanmo Wang; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; acetylcholine; deformation; enzyme monolayer; Biosensor; choline oxidase; dynamic light scattering; exocytosis; quantification; adsorption; acetylcholine esterase; artificial cell; gold nanoparticles; glucose oxidase; nanoparticle tracking analysis; stability; amperometry; enzymatic activity;

    Abstract : During neuronal communication neurotransmitters are released through the process exocytosis that occurs on the time scale of sub-milliseconds to milliseconds. Neuronal activity by neurotransmitters that are non-electroactive cannot easily be monitored due to limitations in the temporal resolutions of the sensor probes for these analytes. READ MORE
