An experimental and modeling study of the shock tube ignition of a mixture of n-heptane and n-propylbenzene as a surrogate for a large alkyl benzene
(Elsevier ScienceDirect, 2012-07-11)
Alkyl aromatics are an important chemical class in gasoline, jet and diesel fuels. In the present work, an n-propylbenzene and n-heptane mixture is studied as a possible surrogate for large alkyl benzenes contained in ...
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 ...
Theoretical chemical kinetic study of the h-atom abstraction reactions from aldehydes and acids by Ḣ Atoms and ȮH, HȮ2, and ĊH3 radicals
(American Chemical Society, 2014-11-11)
We have performed a systematic, theoretical chemical kinetic investigation of H atom abstraction by H atoms and OH, HO2, and CH3 radicals from aldehydes (methanal, ethanal, propanal, and isobutanal) and acids (methanoic ...
Comparison of the performance of several recent hydrogen combustion mechanisms
(Elsevier ScienceDirect, 2014-03-12)
A large set of experimental data was accumulated for hydrogen combustion: ignition measurements in shock tubes (770 data points in 53 datasets) and rapid compression machines (229/20), concentration time profiles in flow ...
Guided waves in pre-stressed hyperelastic plates and tubes: Application to the ultrasound elastography of thin-walled soft materials
(Elsevier, 2017-02-17)
In vivo measurement of the mechanical properties of thin-walled soft tissues (e.g., mitral valve, artery and bladder) and in situ mechanical characterization of thin-walled artificial soft biomaterials in service are of ...
Seismic Rayleigh waves on an exponentially graded, orthotropic half-space
(The Royal Society, 2007)
Efforts at modelling the propagation of seismic waves in half-spaces with continuously varying properties have mostly been focused on shear-horizontal waves. Here, a sagittally polarized (Rayleigh type) wave travels along ...
Evolution and diversity of plant cell walls: from algae to flowering plants
(Annual Reviews, 2011-02-22)
All photosynthetic multicellular Eukaryotes, including land plants and algae, have cells that are surrounded by a dynamic, complex, carbohydrate-rich cell wall. The cell wall exerts considerable biological and biomechanical ...
Reproducible, high-yielding, biological caproate production from food waste using a single-phase anaerobic reactor system
(BMC (part of Springer Nature), 2018-03-11)
Background: Nowadays, the vast majority of chemicals are either synthesised from fossil fuels or are extracted from agricultural commodities. However, these production approaches are not environmentally and economically ...
The integrated stress response
(EMBO Press, 2016-09-14)
In response to diverse stress stimuli, eukaryotic cells activate a common adaptive pathway, termed the integrated stress response (ISR), to restore cellular homeostasis. The core event in this pathway is the phosphorylation ...
