Methodology to analyse small silicon samples by glow discharge mass spectroscopy using thin wafer mask
(Peer reviewed; Journal article, 2015)Glow discharge mass spectrometry (GDMS) is widely used for trace element analysis of bulk solid samples. Thegeometry of the GD source limits the minimum size of the sample, which for the instrument used in this ... -
Methods for K-impregnation of carbon materials and their effect on the CO2 reactivity
(Master thesis, 2022)En veldig stor andel av det norske CO2utslippet kommer som en følge av bruk av fossile karbon materialer i metall produksjon. I den norske mangan (Mn) produksjonen er koks mest brukt til å redusere manganmalmen. Denne ... -
Methods of Oxidation Inhibition for Al-Mg Alloys
(Doctoral theses at NTNU;2019:29, Doctoral thesis, 2019)The oxidation of aluminum will occur at any notable oxygen partial pressure. This oxidation can be favorable as it forms a protective layer on the metal surface which prevents further oxidation. However, the addition of a ... -
