  2. 11. Polymer brush functionalised nanopore sensors

    Author : Julia Järlebark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer brushes; nanopore sensing; nanofabrication;

    Abstract : Single-molecule studies on proteins could reveal a lot of information about their conformational dynamics, and processes such as misfolding and aggregation. This knowledge is valuable in providing a deeper understanding of molecular biology, and for understanding the link between proteins and various diseases. READ MORE

  4. 12. Interactions Between Localized Surface Plasmons and Molecular Resonances

    Author : Gülis Zengin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single particles; J-aggregates; Rhodamine 6G; Localized surface plasmon resonance; strong coupling; surface-enhanced absorption;

    Abstract : Molecular plasmonics is the study of interactions between plasmonic nanostructures and molecules. It has been basis for fundamental understanding of light-matter interactions and development of many technological applications, such as biological and chemical sensing, plasmon-enhanced spectroscopies, optical switches, and plasmon-enhanced energy harvesting.

  5. 13. Nanoparticles based molecular electronic devices with tunable molecular functionalization shell and gas sensing measurements

    Author : Omer Sher; Klaus Leifer; Khaled Saoud; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular electronics; gas sensor; hybrid devices; gold nanoparticles; organic molecules; secondary molecular functionalization process;

    Abstract : The idea to use molecules as a basic building block in electronic circuits was developed about 50 years ago when a molecular rectifier was developed, but it has been a challenge for this field to make its way to real-world application. Now, due to the advancement in technologies, the properties of single molecules are better understandable and controllable. READ MORE

  6. 14. Surface-Induced Modification of Supported Late Transition Metal Complexes

    Author : Olesia Snezhkova; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

    Abstract : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. READ MORE

  7. 15. Tinkering with Light at the Nanoscale using Plasmonic Metasurfaces and Antennas: From Fano to Function

    Author : Mikael Svedendahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosensing; Fano resonances; metamaterials; Surface plasmons;

    Abstract : Surface plasmons are charge density oscillations that can couple strongly to light and be excited in, for instance, thin metal films and metal nanoparticles. The plasmonic excitation squeezes the light down to nanometric length scales, far smaller than the wavelength of the light. READ MORE
