  4. 3. Fabrication and Corrosion Properties of Nickel Silicides Thin Films

    Författare :Eric Tam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel silicides; ion-beam sputter deposition; potentiodynamic polarisation measurements; X-ray photoelectron spectroscopy; corrosion.; thin films;

    Sammanfattning : Surface engineering is a vital issue in engineering materials design. The enhancement of surface properties extends the materials lifetime and improves the materials performance without changing the bulk properties. Thin film deposition is one of the most commonly applied techniques in this field. LÄS MER

  5. 4. Development of Sheathless Electrospray Mass Spectrometry and Investigations of Associated Electrochemical Processes – A Fairy Tale

    Författare :Stefan Nilsson; Karin Markides; Leif Nyholm; Jonas Bergquist; Per Andrén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; electrospray; sheathless; mass spectrometry; capillary electrophoresis; electrochemistry; chromatography; interface; fairy dust; gold; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In microscale separations, such as capillary electrophoresis and -liquid chromatography, the liquid flow rates are in the order of nanoliters per second. If such flow rates are to be interfaced with a mass spectrometer (MS) using electrospray (ES) ionization, without loss of separation efficiency, each fraction of the analyte zone must remain undisturbed by the high voltage contact necessary for ES.

  7. 5. 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
