  1. 6. The Functionalization of Epitaxial Graphene on SiC with Nanoparticles towards Biosensing Capabilities

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Författare :Carl Strandqvist; [2015]
    Nyckelord :Graphene; Epitaxial; Silicon carbide; SiC; Nanoparticles; NPs; TiO2; Fe3O4; Functionalization; Gas sensing; CO; CH2O; C6H6; NH3; Carbon monoxide; Formaldehyde; Benzene; Ammonia; WHO; Hollow cathode; plasma sputtering; AFM; XPS; Raman spectroscopy; Surface characterization; Surface potential; Biosensor; Biosensing;

    Sammanfattning : Graphene has been shown to be very powerful as a transducer in many biosensor applications due to its high sensitivity. This enables smaller surfaces and therefore less material consumption when producing sensors and concequently cheaper and more portable sensors compared to the commercially available sensors today.

  3. 7. Laboratory Spectroscopy of Neutral Scandium, Sc I, for Astrophysical Applications

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Asli Pehlivan; [2012]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Most of the things that we know about stars come from their spectrum. The properties of the atomic lines, e.g. energy levels, wavelengths, oscillator strengths, must be known to understand the observed spectrum and to perform quantitative analyses. LÄS MER

  4. 8. Experimental studies of nucleation and growth of nanoparticles using a pulsed hollow cathode discharge

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Asparuh Stanev; [2011]
    Nyckelord :;

    Sammanfattning : The properties of the nanoparticles are highly eected by their size. In order to apply nanoparticles commercially it is desirable to synthesize them with a narrow size distribution and at high productivity. We synthesized copper nanoparticles (grains) using a plasma generated by a hollow cathode with a pulsed voltage. LÄS MER
