  4. 2. Surface integrity on post processed alloy 718 after nonconventional machining

    Author : Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Manufacturing and materials engineering;

    Abstract : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. READ MORE

  5. 3. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    Author : Deborah Rupert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.

  7. 5. Surface Plasmon Photonics: From Optical Properties of Nanoparticles to Single Molecule Surface-enhanced Raman Scattering

    Author : Hongxing Xu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoparticles; nanostructures; Mie theory; surface plasmon; surface-enhanced Raman scattering; single molecule spectroscopy;

    Abstract : With the rapid development of nanoscience and nanotechnology, surface plasmon photonics using metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for electronic, optical, and sensor applications. In the nanoscale, the physical and chemical properties of metallic particles, especially their optical properties, strongly depend on size and shape, as well as on surrounding media and structures.
