Bærekraftig Gjenvinning av Metaller fra Manganslam via Syreleaching
Eini, Ariel Skaug.; Pedersen, Markus Antonius Elinsønn. (Bachelor thesis, 2022)I oppgaven ble effekten av ulike forsøksparametere på metallutbyttet fra leaching av manganslam undersøkt. Det ble gjort ved å syreleache 13 prøver hvor noen av parameterne ble holdt like og noen ble variert. Tre forskjellige ... -
Complex Frequency-Dependent Polarizability through the π → π* Excitation Energy of Azobenzene Molecules by a Combined Charge- Transfer and Point-Dipole Interaction Model
Haghdani, Shokouh; Davari, Nazanin; Sandnes, Runar; Åstrand, Per-Olof (Journal article; Peer reviewed, 2014)The complex frequency-dependent polarizability and π → π* excitation energy of azobenzene compounds are investigated by a combined charge-transfer and point-dipole interaction (CT/PDI) model. To parametrize the model, we ... -
The Effect of Process Conditions on Sulfuric Acid Leaching of Manganese Sludge
Safarian, Jafar; Eini, Ariel Skaug; Pedersen, Markus Antonius Elinsønn; Haghdani, Shokouh (Peer reviewed; Journal article, 2023)Manganese sludge, an industrial waste product in the ferroalloy industry, contains various components and holds significant importance for sustainable development through its valorization. This study focuses on characterizing ... -
Local electric field factors by a combined charge-transfer and point-dipole interaction model
Davari, Nazanin; Haghdani, Shokouh; Åstrand, Per-Olof; Schatz, George C. (Peer reviewed; Journal article, 2015)A force-field model for the local electric field as a linear response to a frequency-dependent external electric field is presented based on a combined charge-transfer and point–dipole interaction (CT-PDI) force-field model ... -
Optical rotation from coupled cluster and density functional theories
Haghdani, Shokouh (Doctoral theses at NTNU; 2018:31, Doctoral thesis, 2018)Chiral compounds are of fundamental importance in medical chemistry, biochemistry, and industry. Optical rotation, which is one of the most well-known optical responses of chiral molecules to an electromagnetic field, is ... -
A Raman-Structure Model for the Viscosity of SiO2- CaO-Al2O3 System
Haghdani, Shokouh; Tangstad, Merete; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2022)The relationship between structure and viscosity of molten slags is investigated using the Raman spectroscopy technique. To this end, a group of 20 synthetic slags in the SiO2-CaO-Al2O3 ternary system is considered. The ... -
Slag Properties in the Primary Production Process of Mn-Ferroalloys
Tangstad, Merete; Bublik, Sergey; Haghdani, Shokouh; Einarsrud, Kristian Etienne; Tang, Kai (Peer reviewed; Journal article, 2021)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ... -
Solvent Effects on Optical Rotation: On the Balance between Hydrogen Bonding and Shifts in Dihedral Angles
Haghdani, Shokouh; Hoff, Bård Helge; Koch, Henrik; Åstrand, Per-Olof (Journal article; Peer reviewed, 2017)Optical rotations of several conformers of four fluorinated molecules containing the 1-naphthalene or 4-(benzyloxy)phenyl group at the stereocenter have been calculated both in the gas phase and in an aqueous environment. ...
