  1. 1. Mechanistic studies of localized corrosion of Al alloys by high resolution in-situ and ex-situ probing techniques

    Detta är en avhandling från Stockholm : KTH

    Författare :Ali Davoodi; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; localized corrosion; pitting; aluminum alloy; intermetallic particle; Volta potential; cathodic activity; micro-galvanic effect; size dependence; SKPFM; in-situ AFM; integrated AFM SECM; numerical simulation; micrometer resolution; EIS.; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : A multi-analytical approach based on in-situ and ex-situ local probing techniques was employed to investigate localized corrosion mechanisms of some aluminum alloys in chloride containing solutions, focusing on the influence of intermetallic particles (IMPs) in the alloys. In the EN AW-3003 alloy, SEM-EDS analysis revealed constituent and dispersoid IMPs. LÄS MER

  2. 2. Super-resolution Luminescence Micro-Spectroscopy : A nano-scale view of solar cell material photophysics

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Chemical Physics

    Författare :Aboma Merdasa; Lunds universitet.; Lund University.; [2017-01]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; super-resolution microscopy; Single Molecule Spectroscopy; J-aggregates; perovskites; photophysics;

    Sammanfattning : ”Seeing is believing” är ett koncept fött ur människans oändliga nyfikenhet att veta mer. Otvivelaktigt så har modern vetenskap vuxit fram ur denna naturliga strävan efter att vilja veta mer. Från ett tidigt stadium har mikroskopi varit en hörnsten i många vetenskapsdiscipliner. LÄS MER

  3. 3. Corrosion Behavior of Duplex Stainless Steels in Acidic-Chloride Solutions Studied with Micrometer Resolution

    Detta är en avhandling från Stockholm : Materialvetenskap

    Författare :Marc Femenia; KTH.; [2003]
    Nyckelord :In situ; local dissolution; STM; SKPFM; MFM; SAES; duplex stainless steel; acidic-chloride solution;

    Sammanfattning : The local corrosion behavior of duplex stainless steel (DSS)is affected by a wide variety of factors. Localized corrosionof DSS frequently starts at micrometer scale inclusions orprecipitates, which are often segregated in theaustenite-ferrite boundary regions. LÄS MER

  4. 4. Ultrasonic Fluid and Cell Manipulation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mathias Ohlin; KTH.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D cell culture; Acoustic streaming; Acoustofluidics; Cell manipulation; High-resolution imaging; Multi-well; Microplate; Natural killer cell; Piezo; Radiation force; Solid tumor; Solubilization; Spheroid; Standing wave; Temperature control; Transducer; Trapping; Ultrasonic; Physics; Fysik; Biologisk fysik; Biological Physics;

    Sammanfattning : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. LÄS MER

  5. 5. Optical Coherence Tomography for Dermatological Applications

    Detta är en avhandling från Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Författare :Jakob Borup Thomsen; Lunds universitet.; Lund University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; medical imaging; skin cancer diagnostics; optical imaging; blood flow; treatment monitoring;

    Sammanfattning : Popular Abstract in English Cancer diagnostics is an increasingly important task in the modern world due to an increasing cancer incidence and because diagnostics and treatment are given higher priority. There are many requirements to a diagnostic system. LÄS MER
