Magnetoelectric force microscopy on antiferromagnetic 180 degree domains in Cr2O3
(Journal article; Peer reviewed, 2017)Magnetoelectric force microscopy (MeFM) is characterized as methodical tool for the investigation of antiferromagnetic domain states, in particular of the 180 ∘ variety. As reference compound for this investigation we use ... -
Magnetoelectric inversion of domain patterns
(Journal article; Peer reviewed, 2018)The inversion of inhomogeneous physical states has great technological importance; for example, active noise reduction relies on the emission of an inverted sound wave that interferes destructively with the noise of the ... -
Magnetron Sputtering High-Entropy Alloy Coatings: A Mini-Review
(Peer reviewed; Journal article, 2022)Surface coatings can enhance the substrate material’s properties and increase its lifetime. HEA-based materials have been extensively investigated as coating materials due to their superior hardness, excellent oxidation ... -
Major depressive disorder seven years after the conflict in northern Uganda: burden, risk factors and impact on outcomes (The Wayo-Nero Study)
(Journal article; Peer reviewed, 2015)Background Major depressive disorder (MDD) is a major public health burden in conflict areas. However, it is not known for how long and by how much the observed high rates of MDD seen in conflict settings persist into the ... -
Manganese and Aluminium Recovery from Ferromanganese Slag and Al White Dross by a High Temperature Smelting-Reduction Process
(Peer reviewed; Journal article, 2022)The recovery of Mn and Al from two industrial waste of ferromanganese and aluminum production processes was investigated via implementing a high temperature smelting—aluminothermic reduction process. The experiments were ... -
Manganese Oxide in Zinc Electrowinning: Deposition and removal at platinum, gold and IrO2-Ta2O5/Ti anodes in sulphuric acid
(Doctoral theses at NTNU;2021:242, Doctoral thesis, 2021)An environmentally friendly and energy efficient replacement for lead anodes in zinc electrowinning is highly desired. Oxygen evolution reaction (OER) is the desired anode reaction in acidic sulphate electrolytes. However, ... -
Manufacturing of perovskite oxygen carriers by spray granulation for chemical looping combustion
(Journal article; Peer reviewed, 2017)Chemical looping combustion is a technology under development that allows power production with inherent separation of CO2 during fuel combustion. Its principle relies on oxygen carrier materials transporting oxygen from ... -
Mass and Energy Balanced Life Cycle Assessment of Metallurgical Grade Silicon Production
