  2. 16. Kinetic Measurements Using Nanoplasmonic Sensing

    Author : Markus Schwind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Abstract : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. READ MORE

  4. 17. Miniaturized localized surface plasmon resonance biosensors

    Author : Si Chen; Chalmers tekniska högskola; []
    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.

  5. 18. Electrokinetic devices from polymeric materials

    Author : Katarina Bengtsson; Nathaniel D Robinson; Mats Fahlman; Jörg P. Kutter; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : There are multiple applications for polymers: our bodies are built of them, plastic bags and boxes used for storage are composed of them, as are the shells for electronics, TVs, computers, clothes etc. Many polymers are cheap, and easy to manufacture and process which make them suitable for disposable systems.

  6. 19. Adding Utility to Carbon Materials: Introducing Dopants Using Highly Soluble Metal Salts and Functionalizing Surfaces via Bromomethylation

    Author : Samuel Joseph Fretz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon materials; fuel cells; Li-S batteries; surface functionalization; doping;

    Abstract : Carbon-based materials have received intense research interest over the past few decades due to their unique  combination of properties including porosity, non-toxicity, chemical inertness, low density, and electrical conductivity, which has allowed them to find a wide array of applications including supercapacitors, batteries, CO2 capture, fuel cells, and catalysis. To expand their utility, a variety of techniques have been developed to enhance their reactivity and functionality. READ MORE

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

    Author : Teodora Retegan Vollmer; Chalmers tekniska högskola; []
