(Peer reviewed; Journal article, 2016-01)A battery of methods for multivariate data analysis has been used to assess the associations between concentrations of fatty acids (FAs) and lipoprotein subclasses and particle size in serum for a normolipidemic population ... -
Preliminary observations of the interplay of radiation damage with spin crossover
(Journal article; Peer reviewed, 2022)Intense synchrotron radiation makes time-resolved structural experiments with increasingly finer time sampling possible. On the other hand, radiation heating, radiation-induced volume change and structural disorder become ... -
Probing Catalyst Degradation in Metathesis of Internal Olefins: Expanding Access to Amine-Tagged ROMP Polymers
(Journal article; Peer reviewed, 2023)Ruthenium-promoted ring-opening metathesis polymerization (ROMP) offers potentially powerful routes to amine-functionalized polymers with antimicrobial, adhesive, and self-healing properties. However, amines readily degrade ... -
Probing myelin-specific membrane proteins using hybrid nanoparticles
(Master thesis, 2020-12-03)Neuroscience is the study of the nervous system and its diseases. Neurological diseases are common and among the least understood class of disease in humans. Demyelinating diseases,, such as multiple sclerosis and ... -
Probing the elastic response of lipid bilayers and nanovesicles to leaflet tensions via volume per lipid
(Journal article; Peer reviewed, 2023)Biological and biomimetic membranes are based on lipid bilayers, consisting of two monolayers or leaflets. One important but challenging physical parameter of these membranes is their tension. For a long time, this tension ... -
Process Monitoring of Continuous Flow Organic Syntheses by means of Inline Fiber Optical Raman Spectroscopy
(Master thesis, 2010-02-08)The objective of the current study was to investigate the feasibility of the inline optical fiber Raman spectroscopy as a tool for the process monitoring of the continuous flow organic syntheses. The synthesis of 2-bromo-3,4,5- ... -
The production and characterization of drug-loaded liposomal and PLGA nanocarriers for targeted treatment of acute myeloid leukemia
(Master thesis, 2016-06-01)While some progress has been made lately in developing transplantation therapy against acute myeloid leukemia (AML), it remains a problematic and aggressive disease, associated with both poor survival, as well as treatments ... -
A project in renewable fuels: A study of the catalytic activity of sulfated H-Ni-Mo catalyst on ZrO2 support in the LtL-process, and development of ESI-MS method for biooils
(Master thesis, 2015-09-18)Examining the effect of a hydrogenated Ni-Mo catalyst on a zirconia support for the LtL-process and an attempt at developing a method for ESI-MS analysis of the biooils produced. Biofuels produced from lignocellulosic ... -
Promoting Coherent Science Instruction through Coherent Science Teacher Education: A Model Framework for Program Design
(Journal article; Peer reviewed, 2021)Recent research and reform efforts in science education have consistently stressed the importance of coherent science instruction, in which learning opportunities are connected and contextualized by meaningful phenomena, ... -
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 ... -
