    Author : Alexander Wärnheim; C. Magnus Johnson; Per M. Claesson; Dan Persson; Carita Kvarnström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Anti-corrosion coatings; Coil coating; Weathering; FTIR; nano-FTIR; Hyperspectral imaging; AFM; Nanomechanical properties; korrosionsskyddsbeläggnignar; bandlackerade beläggningar; väderbeständighetstestning; FTIR; nano-FTIR; hyperspectral avbildning; Atomkraftsmikroskopi; nanomekaniska egenskaper; Kemi; Chemistry;

    Abstract : Coil coatings are durable  organic coatings used to protect metal sheets from corrosion and improve their aesthetic properties. Because of their extensive use, coil coatings have long been of interest for industrial and academic researchers. READ MORE

  2. 22. Automated super-resolution microscopy for high-throughput imaging

    Author : Xavier Casas Moreno; Ilaria Testa; Florian Jug; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; throughput; microscopy automation; nanoscopy; Biologisk fysik; Biological Physics;

    Abstract : Fluorescence microscopes enable the visualization of biological samples with high contrast by labeling specific structures with fluorescent molecules. However, the spatial resolution of widely used microscopy techniques, such as widefield and confocal microscopy, is limited by the size of a focused spot of light, which roughly corresponds to half the wavelength of the illumination.

  3. 23. From green to yellow : a leaf story

    Author : Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

    Abstract : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. READ MORE

  4. 24. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

    Author : Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
    Keywords : Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

    Abstract : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. READ MORE

  5. 25. Probing Interactions between Bio-Fibre Components

    Author : Niklas Nordgren; Mark Rutland; Harry Brumer; Vincent Bulone; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AFM; QCM-D; cellulose; xyloglucan; surface forces; friction; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; self assembly; grafting; thiol; spring constant; calibration; photodetector calibration.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : I den här avhandlingen har atomkrafts mikroskopi (AFM) och kvartskristall mikrovåg med dissipation (QCM-D) används för att undersöka interaktioner i bio-fiber modell system av cellulosa och xyloglukan (XG); en naturligt förekommande polysackarid viktig för tillväxt av träd och andra växter. Dessutom har det avgörande momentet av friktionskrafts-kalibrering studerats för att erhålla noggranna och kvantitativa resultat med kolloidal prob AFM. READ MORE
