Properties of activated carbon regulated by rapid cooling treatment after pyrolysis
(Peer reviewed; Journal article, 2019)Effects of rapid cooling following pyrolysis were studied relative to the properties of activated carbon using different biomass as the raw materials. Coconut shell-based activated carbon (CSAC), bamboo-based activated ... -
Properties of multicrystalline silicon wafers and case study of PV module viability analysis
(Master thesis, 2017)Multicrystalline silicon solar cells are becoming a major stream technology. The main reason is the increase of efficiency of solar cells and constant production costs decline. In some countries PV can directly compete ... -
Properties of TSA in natural seawater at ambient and elevated temperature
(Journal article; Peer reviewed, 2019)Electrochemical properties of thermal sprayed aluminium (TSA) coating were investigated in natural seawater at elevated temperatures with and without cathodic protection (CP). TSA has a low current density requirement when ... -
Protective films on molten magnesium
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:7, Doctoral thesis, 2004)Molten magnesium will oxidize uncontrollably in an atmosphere of air. To inhibit this, a protective gas is used to cover the melt. The gas most commonly used today is SF6. Fluorine is known to be the active component of ... -
