A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2017-11-01) Vainio-Kaila, Tiina; Zhang, Xue; Hänninen, Tuomas; Kyyhkynen, Aino; Johansson, Leena Sisko; Willför, Stefan; Österberg, Monika; Siitonen, Anja; Rautkari, LauriAntibacterial properties of wood structural components and extractives were investigated against methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli O157:H7 by placing bacterial inoculum on the model surfaces and incubating them for 2, 4, and 24 h. After incubation, the amount of viable bacteria on the surfaces was studied. The film coverage and thickness were evaluated with atomic-force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The extracts were analyzed with gas chromatography-mass spectrometry (GC-MS). The results showed that films fully covered the glass surfaces. The XPS results confirmed the analysis of GC-MS, which revealed more similarities between the extractives of pine heartwood and spruce heartwood than between pine heartwood and pine sapwood. Only the pine heartwood extract showed an antibacterial effect against E. coli O157:H7. In contrast, MRSA was susceptible to all of the extracts and milled wood lignin (MWL). - Antifouling-pinnoitemateriaalien käyttäminen titaanista valmistetuissa hammasimplanteissa

Kemiantekniikan korkeakoulu | Bachelor's thesis(2020-06-01) Kattelus, Joakim - Artificial Weathering of Contact-Charred Wood—The Effect of Modification Duration, Wood Species and Material Density
A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2022-06-01) Kymäläinen, Maija; Sjökvist, Tinh; Dömény, Jakub; Rautkari, LauriA relevant issue with charred exteriors is the inconsistency of the result, which makes service life predictions complicated. Contact charring enables the creation of a very evenly modified surface with accurate control of temperature and modification time, but the weathering properties are questionable. This paper evaluated the effect of the modification time relative to char layer and transition zone thickness, wood species and material density in an artificial weathering test. The results revealed higher color stability in connection to longer modification time, but also an increase in the cracked surface area. Cracking was heavily dependent on the modification regime and increased with increasing char and transition zone thicknesses. Dense spruce had the highest color stability with the most severe modification regime, but char layer thickness varied more than on other wood types. Furthermore, species-dependent cracking patterns affected the final result as the small-scale flaking experienced by birch increased the washing off of char. It is likely an even higher modification temperature with a shorter modification time is needed to produce sufficient weathering resistance suitable for exterior uses. - Arvotuotteita hiilidioksidista
