  1. 1. Surface Force and Friction : effects of adsorbed layers and surface topography

    Författare :Xiaoyan Liu; Per Claesson; Bjorn Torger Stokke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

    Sammanfattning : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. LÄS MER

  3. 2. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Författare :Tobias Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. LÄS MER

  4. 3. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

    Författare :Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

    Sammanfattning :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. LÄS MER

  5. 4. Advances in Soft Matter Nanofabrication

    Författare :Mehrnaz Shaali; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photolithography; negative e-beam resist; monolayer; confocal microscopy; Teflon AF; KPFM; DNA origami; cells; lipid nanotube; AFM; double bilayer; Phospholipid; electron beam lithography;

    Sammanfattning : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. LÄS MER
