Optimization of a hydrogen combustion mechanism using both direct and indirect measurements
(Elsevier ScienceDirect, 2014-07-05)The Keromnes et al. (2013) mechanism for hydrogen combustion has been optimized using a large set of indirect experimental data, consisting of ignition measurements in shock tubes (566 datapoints in 43 datasets) and rapid ... -
Optimized reaction mechanism rate rules for ignition of normal alkanes
(Elsevier, 2016-08-10)The increasing demand for cleaner combustion and reduced greenhouse gas emissions motivates research on the combustion of hydrocarbon fuels and their surrogates. Accurate detailed chemical kinetic models are an important ... -
The oxidation of 2-butene: A high pressure ignition delay, kinetic modeling study and reactivity comparison with isobutene and 1-butene
(Elsevier, 2016-06-16)Butenes are intermediates ubiquitously formed by decomposition and oxidation of larger hydrocarbons (e.g. alkanes) or alcohols present in conventional or reformulated fuels. In this study, a series of novel igni-tion delay ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 2014-03-26)Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 2014-03-27)A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ... -
Oxidative stress induced by Pt(IV) pro-drugs based on the cisplatin scaffold and indole carboxylic acids in axial position
(Nature Publishing Group, 2016-06-11)The use of Pt(IV) complexes as pro-drugs that are activated by intracellular reduction is a widely investigated approach to overcome the limitations of Pt(II) anticancer agents. A series of ten mono- and bis-carboxylated ... -
Performance Monitoring of a Mammalian Cell Based Bioprocess using Raman spectroscopy.
(2013)Being able to predict the final product yield at all stages in long-running, industrial, mammalian cell culture processes is vital for both operational efficiency, process consistency, and the implementation of Quality by ... -

A phosphate-targeted dinuclear Cu(II) complex combining major groove binding and oxidative DNA cleavage
(Oxford University Press, 2018-09-17)Free radical generation is an inevitable consequence of aerobic existence and is implicated in a wide variety of pathological conditions including cancer, cardiovascular disease, ageing and neurodegenerative disorder. Free ... -
Planar [Ni-7] discs as double-bowl, pseudo metallacalix[6]arene host cavities
(RSC, 2010-09-19)We report three heptanuclear[Ni-7] complexes with planar disc-like cores, akin to double-bowl metallocalix[6]arenes, which form molecular H-bonded host cavities. -
