  1. 1. Miniaturized localized surface plasmon resonance biosensors

    Author : Si Chen; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Abstract : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

  2. 2. Porous polymeric materials for chromatography Synthesis, functionalization and characterization

    University dissertation from Umeå : Kemiska Institutionen, Umeå universitet

    Author : Emil Byström; Knut Irgum; Camilla Viklund; Solomon Tesfalidet; Klaus K Unger; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; porous polymer monolith; pore size distribution; nitrogen sorptiometry; mercury intrusion porosimetry; scanning and transmission electron microscopy; plasma functionalization; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry Separation methods; NATURVETENSKAP Kemi Analytisk kemi Separationsmetoder; NATURAL SCIENCES Chemistry Organic chemistry Polymer chemistry; NATURVETENSKAP Kemi Organisk kemi Polymerkemi; analytisk kemi; Analytical Chemistry;

    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.

  3. 3. Investigations of Solvent Systems Based on bis-triazine-bipyridine (BTBP) - class Ligands for the Separation of Actinides from Lanthanides

    University dissertation from Umeå : Kemiska Institutionen, Umeå universitet

    Author : Teodora Retegan Vollmer; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lanthanides; diluents; BTBP; solvent extraction; side groups; complexes; actinides;

    Abstract : Shortages of fossil fuel and other political movements contributed to the nuclear energy “renaissance”.Nuclear energy, however, is not free of challenges, one of them being nuclear waste management. READ MORE

  4. 4. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    University dissertation from Umeå : Kemiska Institutionen, Umeå universitet

    Author : Mikhail S Tyumentsev; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Abstract : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tuija Pihlström; Karin E Markides; Bengt-Göran Österdahl; Amadeo Rodríguez Fernández-Alba; [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.
