Formation of an Isomeric Mixture of Dienynes Instead of a Diallene
(Journal article, 2020)Attempts to convert 1,1,2,2,7,7,8,8-octaethoxyocta-3,5-diyne to a symmetric allene by reduction with lithium aluminum hydride failed. Instead reduction accompanied by isomerization occurred and afforded 1,1,2,7,8,8-hexae ... -
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 ... -
A comparison of analytical approaches to investigate associations for accelerometry-derived physical activity spectra with health and developmental outcomes in children
(Journal article; Peer reviewed, 2021)The use of high-resolution physical activity intensity spectra obtained from accelerometry can improve knowledge of associations with health and development beyond the use of traditional summary measures of intensity. The ... -
Interpretation of associations between the accelerometry physical activity spectrum and cardiometabolic health and locomotor skills in two cohorts of children using raw, log-transformed, or compositional data
(Journal article; Peer reviewed, 2020)It is discussed whether associations between accelerometer-derived physical activity intensities and outcomes should be analysed as absolute or relative data. The aim of the present study was to compare interpretation of ... -
Variable importance: Comparison of selectivity ratio and significance multivariate correlation for interpretation of latent‐variable regression models
(Journal article; Peer reviewed, 2020)This work examines the performance of significance multivariate correlation (sMC) and selectivity ratio (SR) for ranking variables according to their importance in latent-variable regressions (LVRs) models. Both indices ... -
Challenging Metathesis Catalysts with Nucleophiles and Brønsted Base: Examining the Stability of State-of-the-Art Ruthenium Carbene Catalysts to Attack by Amines
(Journal article; Peer reviewed, 2020)Critical to advancing the uptake of olefin metathesis in leadingcontexts, including pharmaceutical manufacturing, is identification of highlyactive catalysts that resist decomposition. Amines constitute an aggressivechallenge ... -
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 ... -
Novel and colourful flavonoids - characterisation, secondary structures and properties
