Electron spectroscopic study of passive oxide layer formation on Fe–19Cr–18Ni–1Al–TiC austenitic stainless steel
TL;DR: In this article, the surface oxidation of a TiC-enriched austenitic stainless steel alloy was investigated at 50°C by X-ray photoelectron spectroscopy (XPS) and Xray absorption spectrum analysis (XAS) and it was found that a passive oxide layer started to form on the alloy surface after 5 l of oxygen exposure.
Journal ArticleDOI
Novel laboratory-scale preparation and characterisation of BaLn2PtO5 (Ln: Nd, Eu, Sm, Gd) as exhaust gas catalyst precursors
M. Hietikko,S. Suhonen,J. Pursiainen,Risto S. Laitinen,Mika Valden,A. Savimäki,T Slotte,Härkönen +7 more
TL;DR: In this paper, the performance of the catalysts were characterized by powder-XRD, XPS and TGA/DTA, and the results indicated that all phases were thermally stable up to 1250°C.
Journal ArticleDOI
Biofunctional hybrid materials: bimolecular organosilane monolayers on FeCr alloys
Leena Vuori,Jenni Leppiniemi,Markku Hannula,Kimmo Lahtonen,M. Hirsimäki,Ergo Nõmmiste,Leila Costelle,Vesa P. Hytönen,Mika Valden +8 more
TL;DR: The obtained insights into molecular bonding, orientation, and behaviour of surface-confined organofunctional silanes on SS enable a new generic approach to functionalization of SS surfaces with versatile nanomolecular organosilane layers.
Journal ArticleDOI
Improved Corrosion Properties of Hot Dip Galvanized Steel by Nanomolecular Silane Layers as Hybrid Interface Between Zinc and Top Coatings
Leena Vuori,Harri Ali-Löytty,Kimmo Lahtonen,Markku Hannula,Elina Lehtonen,Yuran Niu,Mika Valden +6 more
TL;DR: In this article, the fabrication of a nanomolecular silane film as an interfacial layer between the hot dip galvanized steel (HDGS) and TOC or paint improves the corrosion properties of HDGS in different pH regimes.
Journal ArticleDOI
Displacement of chemisorbed 12 CO from Pd{110} by adsorbing hot precursor 13 CO molecules
TL;DR: In this article, the displacement kinetics of CO precovered Pd{110} surface by incident CO were investigated as a function of surface temperature and translational energy by employing a molecular beam surface scattering technique with supersonic molecular beams of isotopically labeled CO molecules.
