  1. 1. Nanoplasmonic Structures for Bio/Chemo Sensing

    Författare :Tomas Rindzevicius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface-enhancement; biorecognition; nanostructures; surface plasmons; nanoholes.; biosensing;

    Sammanfattning : Localized surface plasmon resonances (LSPR's) in noblemetal nanostructures are sensitive to refractive index changes close to the metal surface, and the LSPR's can therefore be utilized to sense molecular binding reactions. This thesis focuses on fundamental properties and proof-of-principle sensing studies of nanoplasmonic structures relevant for molecular detection. LÄS MER

  4. 3. Quantitative Surface Enhanced Raman Spectroscopy

    Författare :Anders Lorén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gold colloids; internal standard; surface enhanced Raman spectroscopy; SERS; PLS; PCA; SAM; quantitative;

    Sammanfattning : Surface enhanced Raman spectroscopy (SERS) is a very attractive technique for detection of various organic and inorganic molecules due to its sensitivity and selectivity. The surface enhancement is achieved when the molecules of interest are on or in the vicinity of a metal surface, usually gold and silver. LÄS MER

  5. 4. Applications in Surface Enhanced Raman Spectroscopy

    Författare :Charlotte Eliasson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SERS; surface enhanced Raman spectroscopy; image analysis; lymphocytes; PCA; doxorubicin; living cells; PLS;

    Sammanfattning : The aim of this thesis is to address specific applications of Raman spectroscopy and specifically surface enhanced Raman spectroscopy, SERS. It includes an introduction to the techniques and several applications. The focus has been on how to achieve high precision SERS measurements, both qualitatively and quantitatively. LÄS MER

  7. 5. Surface Integrity and Fatigue Performance of Nickel-based Superalloys

    Författare :Zhe Chen; Ru Peng; Johan Moverare; Sten Johansson; Manuel François; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Due to global warming, the demand for more efficient gas turbines has increased. A way to achieve this, is by increasing the operating temperature of the gas turbine. Therefore, nickel-based superalloys have been developed to withstand these extreme temperatures and loads, especially in the hot sections. LÄS MER
