Hydrophobic and superhydrophobic surfaces were field-tested on two locations in a paper machine to see the easy-to-clean property, compared with a reference surface. One test site was near machine wire which was wet place exposed to fibres and wood extracts, and the other was at size roll, where was much drier and surfaces were exposed to glue aerosol. The test period was 16 days. At the end of the...
By using the sol-gel technique and the liquid flame spray method (LFS), three different iron oxide doped alumina-based catalysts (Catalysts A, B and C) were prepared by using iron nitrate and ferrocene as the iron source. Multiwalled carbon nanotubes were obtained by a decomposition of methane gas over Catalysts A and C, but not over Catalyst B. X-ray diffraction, transmission electron microscopy...
