Purple anthocyanin colouration on lower (abaxial) leaf surface of Hemigraphis colorata (Acanthaceae)
(Peer reviewed; Journal article, 2014-09)The functional significance of anthocyanin colouration of lower (abaxial) leaf surfaces is not clear. Two anthocyanins, 5-O-methylcyanidin 3-O-(3″-(β-glucuronopyranosyl)-β-glucopyranoside) (1) and 5-O-methylcyanidin ... -
Pyridine-Stabilized Fast-Initiating Ruthenium Monothiolate Catalysts for Z-Selective Olefin Metathesis
(Peer reviewed; Journal article, 2017)Pyridine as a stabilizing donor ligand drastically improves the performance of ruthenium monothiolate catalysts for olefin metathesis in comparison with previous versions based on a stabilizing benzylidene ether ligand. ... -
Qualification of New Methods for Measuring In-Situ Rheology of Non-Newtonian Fluids in Porous Media
(Journal article; Peer reviewed, 2020)Pressure drop (ΔP) versus volumetric injection rate (Q) data from linear core floods have typically been used to measure in situ rheology of non-Newtonian fluids in porous media. However, linear flow is characterized by ... -
Quantification of Polyphenols in Seaweeds: A Case Study of Ulva intestinalis
(Peer reviewed; Journal article, 2019-12-03)In this case study, we explored quantitative 1H NMR (qNMR), HPLC-DAD, and the Folin-Ciocalteu assay (TPC) as methods of quantifying the total phenolic content of a green macroalga, Ulva intestinalis, after optimized ... -
Quantitative NMR analysis of the aqueous phase from hydrothermal liquefaction of lignin
(Journal article; Peer reviewed, 2020-08-06)Hydrothermal liquefaction (HTL) of biomass such as lignin could contribute to finding replacements for petroleum, both as a fuel and production of chemicals. The organic phase produced in formic acid assisted HTL of lignin ... -
Quantum Control of Rydberg Atoms
(Master thesis, 2014-06-02)In 2007 the AEGIS experiment was started at CERN with the goal to determine the gravitational acceleration of the antihydrogen atom. This is achieved through accelerating the antihydrogen atoms toward a detector and measure ... -
Question classification taxonomies as guides to formulating questions for use in chemistry classrooms
(Peer reviewed; Journal article, 2016)Teacher questions play an important role in facilitating classroom discourse. Using appropriate question types and proper questioning techniques help to create reflective- active learners. Teacher questions can elicit ... -
Quinolone-DNA interactions. Interactions and association between Ofloxacin and a DNA-oligomer studied by NMR methods
(Master thesis, 2003)The first part of this thesis examines Ofloxacin (Oflo), a second-generation quinolone, by applying 1D 1H NMR. Molecular dynamics, stacking conditions and the self-diffusion constant were investigated. No certain conclusion ... -
Radioactive contamination in sediments near the sunken nuclear submarine Komsomolets, SW of Bear Island in the Norwegian Sea
(Master thesis, 2014-06-02)The Soviet nuclear submarine Komsomolets sank on the 7th of April 1989, 185 km southwest of the Bear Island in the Norwegian Sea to a depth of about 1655 m. The submarine contains one nuclear reactor, containing long-lived ... -
