Pulsed laser growth of La2NiMnO6 for intermediate band solar cells
(Master thesis, 2022)Mellombåndssolceller har vist stort potensiale for å øke effektiviteten til fotoelektriske enheter, og samtidig redusere kostnaden knyttet til produsert elektrisitet. Funksjonelle oksidmaterialer, som doble perovskitter, ... -
Pump-probe experiments of multicrystalline silicon for solar cell applications
(Master thesis, 2012)In order to make cost effective solar cells from mc-Si materials, the negative contributions from defects and impurities should be reduced. The analysis of the photogenerated carrier properties is therefore of great ... -
Pure and Zr-doped YMnO3+δ as a YSZ-compatible SOFC cathode: a combined computational and experimental approach
(Journal article; Peer reviewed, 2019)A thorough study of the Y1−xZrxMnO3+δ series is presented with the objective to use these materials as SOFC cathodes. These pure and Zr-doped yttrium manganites exhibit a layered hexagonal structure similar to a peculiar ... -
Pure spin current generated by reflection at a normal metal/two-dimensional electron gas interface
(Journal article; Peer reviewed, 2010)The concept of a spin current is a useful tool in understanding spin transport in hybrid systems but its very definition is problematic in systems where spin-orbit coupling effects are strong. In the absence of spin-dependent ... -
Purification and characterization of an unusual DNA glycosylase in diatoms
(Master thesis, 2012)DNA damage may be caused by many different agents, including radiation, spontaneous mutations and chemical mutagens. If the damage is left unrepaired, it may result in mutations or cell death. All organisms contain repair ... -
Purification and characterization of design mannuronan C5-epimerases
(Master thesis, 2019)Alginates are a family of linear polysaccharides composed of 1,4-linked β-D-mannuronic acid (M) and α-L-guluronic acid (G) monomer units. The two sugar molecules can only be distinguished by an opposite stereochemical ... -
Purification and impurity uptake of hydrated Nickel sulfate salts from aqueous solution with common process impurities
(Master thesis, 2019)Nikkelsulfat salter er en av komponentene som brukes i katoden av moderne Lithium-ion batterier i elektriske biler. Batterigrad nikkelsulfat salter er rengjort og separert via krystallisasjon. Glencore Nikkelverk AS ... -
Purification of Silicon Through a Hydrometallurgical Process
(Master thesis, 2017)The demand for cleaner energy is rising because of the global warming and because of the access of fossil energy one day will come to an end. For encounter this demand, solar cells have a huge potential. Today the market ... -
Pursuing New Cathode Materials for Rechargeable Magnesium Batteries
(Doctoral theses at NTNU;2021:65, Doctoral thesis, 2021)High-performance and safe batteries based on cheap and sustainable materials are highly desirable to accelerate the transition to a renewable energy-based society. The ongoing electrification of the transport sector has ... -
Pursuing Sustainable Cathodes with High Rate Capability
(Master thesis, 2022)Litium-ionebatterier (LiBer) er forventet å bli en av fremtidens viktigste energilagringskilder, da de gir mulighet for å lagre og bruke energi uten å produsere drivhusgasser. CO2-fotavtrykket til LiBer er derimot i stor ... -
PVA-assisted combustion synthesis and characterization of porous nanocomposite Li2FeSiO4/C
(Journal article; Peer reviewed, 2012)Porous Li2FeSiO4/C nanocomposites were synthesized by a PVA-assisted combustion method, and phase pure Li2FeSiO4 was produced for samples prepared with 20 and 30 wt.% starch. The electrochemical properties of the Li2FeSiO4/C ... -
PVA/nanocellulose nanocomposite membranes for CO2 separation from flue gas
(Peer reviewed; Journal article, 2019)In this paper, we explore the use of nanocelluloses as an additive to poly (vinyl alcohol) (PVA) nanocomposite membranes for CO2/N2 mixed-gas separation. Our findings are that several types of nanocellulose can be used to ... -
PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO2 separation performance
(Journal article; Peer reviewed, 2019)CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water ... -
