1. 6. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis

   Författare :Svetlana Alekseeva; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; grain boundary; metal-hydrogen interactions; plasmonic sensors; single particle spectroscopy; palladium nanoparticles and nanocrystals; localized surface plasmon resonance; hole-mask colloidal lithography; nanocatalysts; shrinking-hole colloidal lithography; plasmonic nanospectroscopy; dark field scattering spectroscopy; nanoscale effects;

   Sammanfattning : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. LÄS MER

3. 7. Novel Functionalized Nanopores for Plasmonic Sensing

   Författare :Bita Malekian; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extinction spectra; nanopores; proteins; nanocaves; nanowells; surface plasmon resonance; nuclear pore complex; colloidal lithography; nanoplasmonic sensor; label-free sensing; electron beam lithography; plasmonic nanostructures;

   Sammanfattning : Nanoplasmonic sensors offer a label-free platform for real-time monitoring of biomolecular interactions by tracking changes in refractive index through optical spectroscopy. However, other surface sensitive techniques such as conventional surface plasmon resonance offer similar capabilities with equal or even better resolution in terms of surface coverage. LÄS MER

4. 8. Electronic paper in color by electrochromic materials and plasmonics

   Författare :Oliver Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromism; reflective displays; plasmonic electronic paper; conjugated polymers; structural color; plasmonic;

   Sammanfattning : The most common display today is emissive. It produces its own light and emits it to the viewer's eye. A reflective display, also known as electronic paper, uses ambient light and reflects it to the viewer, just like a newspaper. LÄS MER

5. 9. 3D-Printing of Fluorinated Polymer-based Materials for Plasmonic Sensing

   Författare :Ida Östergren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D-printing; polymer nanocomposite; hydrogen sensing; plasmonic nanoparticles; Teflon AF; fused deposition modeling;

   Sammanfattning : Hydrogen attracts growing interest as a versatile energy carrier, serving as a fuel for cars, a heat source, or a reagent for chemical synthesis. At the same time, the demand for accurate and selective hydrogen sensors is increasing because of both safety concerns and the need for process monitoring. LÄS MER

7. 10. Advanced all-fiber optofluidic devices

   Författare :Sebastian Etcheverry Cabrera; Fredrik Laurell; Markus Schmidt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber optics; functional fiber probes; optofluidics; microfluidics; plasmonic; all-fiber technology; instrumentation for life-sciences.; Physics; Fysik;

   Sammanfattning : Significant technological advances of the last years have been possible by developments in Optofluidics, which is a field that deals with the integration of optics and microfluidics into single devices.The work described in this thesis is based on five scientific publications related to the use of fiber optic technology to build integrated optofluidic devices.
