  2. 16. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

  4. 17. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS

    Author : Zhaleh Pirzadeh Irannezhad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localized surface plasmon resonance; interband transition; nanoantenna; nickel nanoplasmonic; coupling;

    Abstract : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). READ MORE

  5. 18. Nanoplasmonics for Absorption Engineering and Hydrogen Sensing

    Author : Carl Wadell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium; hydrogen storage; absorption engineering; nanoplasmonic sensing; nanosize effects; plasmon enhanced chemistry; Localized surface plasmon resonance;

    Abstract : When light interacts with metallic nanoparticles smaller than its wavelength it can excite a collective oscillation of the conduction electrons that gives rise to efficient light absorption and scattering. Moreover, locally strongly enhanced electric fields are created around the particles. READ MORE

  6. 19. Plasmonic Nanostructures for Optical Absorption Engineering and Hydrogen Sensing

    Author : Carl Wadell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; metal hydride; alloy nanoparticles; palladium; absorption engineering; plasmon enhanced chemistry; nanoplasmonic sensing; nanoparticle size effects; localized surface plasmon resonance; hydrogen sensing;

    Abstract : Nanoplasmonics concerns the interactions between light and metal nanoparticles. In this thesis nanoplasmonics is used in two different ways: i) to control and enhance light absorption, and ii) for optical hydrogen sensing. READ MORE

  7. 20. Fragment Based Drug Discovery with Surface Plasmon Resonance Technology

    Author : Helena Nordström; Helena Danielson; Gregg Siegal; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fragment based drug discovery; SPR biosensor; matrix metalloproteinase-12; HIV-1 protease; resistance;

    Abstract : Fragment based drug discovery (FBDD) has been applied to two protease drug targets, MMP-12 and HIV-1 protease. The primary screening and characterization of hit fragments were performed with surface plasmon resonance -technology. Further evaluation of the interaction was done by inhibition studies and in one case with X-ray crystallography. READ MORE
