P removal from Si by Si-Ca-Al alloying-leaching refining: Effect of Al and the CaAl2Si2 phase
(Peer reviewed; Journal article, 2021)Phosphorus (P) is a critical impurity in metallurgical-grade Si that needed to be removed for solar-grade Si production. The Si-Ca-Al-P system is one of the most crucial alloy systems for Si refining, where P can be separated ... -
p-wave triggered superconductivity in single layer graphene on an electron-doped oxide superconductor
(Journal article; Peer reviewed, 2017)Electron pairing in the vast majority of superconductors follows the Bardeen–Cooper–Schrieffer theory of superconductivity, which describes the condensation of electrons into pairs with antiparallel spins in a singlet state ... -
p62/SQSTM1 sin rolle i regulering av type I interferon-responsen i metastaserende brystkreftceller
(Bachelor thesis, 2019)Kreft er en genetisk sykdom som karakteriseres av ukontrollert proliferasjon av celler i et vev. Brystkreft er en av de hyppigste kreftformene på verdensbasis, og har også flest overlevelser i Norge. Det er flere typiske ... -
PAH emissions from the metallurgical industry
(Doctoral theses at NTNU;2023:269, Doctoral thesis, 2023)Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic molecules consisting of two or more fused aromatic rings. They can be created by incomplete combustion of organic materials and accumulate in nature. As ... -
A pain-causing and paralytic ant venom glycopeptide
(Journal article; Peer reviewed, 2021)Ants (Hymenoptera: Formicidae) are familiar inhabitants of most terrestrial environments. Although we are aware of the ability of many species to sting, knowledge of ant venom chemistry remains limited. Herein, we describe ... -
A pair of esterases from a commensal gut bacterium remove acetylations from all positions on complex β-mannans
(Peer reviewed; Journal article, 2020)β-mannans and xylans are important components of the plant cell wall and they are acetylated to be protected from degradation by glycoside hydrolases. β-mannans are widely present in human and animal diets as fiber from ... -
A paleogenomic investigation of overharvest implications in an endemic wild reindeer subspecies
(Peer reviewed; Journal article, 2024)Overharvest can severely reduce the abundance and distribution of a species and thereby impact its genetic diversity and threaten its future viability. Overharvest remains an ongoing issue for Arctic mammals, which due to ... -
Palladium alloy model systems forunderstanding the surface properties of Pd-based membranes and catalysts
(Doctoral Theses at NTNU, 1503-8181; 2014:9, Doctoral thesis, 2014)Palladium has high solubility, permeability and selectivity for hydrogen, thus being a suitable membrane material for hydrogen separation. In addition, palladium is a versatile catalyst with applications in industrial ... -
Palladium Catalyzed Cross-Coupling Reactions on 7-Azaindoles in the Synthesis of CSF1R Inhibitors
(Master thesis, 2019)Overuttrykk av colony stimulating factor 1 receptor (CSF1R) tyrosin kinase er blitt linket til flere sykdommer, blant annet kreft, benosteolyse og betennelseslidelser. En lovende behandlingsstrategi for disse sykdommene ... -
Palladium(0)-Catalyzed Cross-Couplings of 2-Bromophosphinine
(Journal article; Peer reviewed, 2013)A new Negishi-type cross-coupling of 2-bromophosphinine has been developed. The new method expands the scope of palladium-catalyzed couplings to monobromophosphinines, which have been considered as poor substrates so far. ... -
PAMP-INDUCED SECRETED PEPTIDE 3 (PIP3) modulates immunity in Arabidopsis thaliana
(Journal article; Peer reviewed, 2019)Small post-translationally modified peptides are important signalling components of plant defence responses against phytopathogens, acting both as positive and negative modulators. PAMP-INDUCED SECRETED PEPTIDE (PIP) 1 and ... -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
(Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ... -
