Fermentative hydrogen production from cheese whey with in-line, concentration gradient-driven butyric acid extraction
(Elsevier, 2020-08-01)
Hydrogen (H2) generation from cheese whey with simultaneous production and extraction of volatile fatty acids (VFAs) was studied in UASB reactors at two temperatures (20 and 35 °C) and pH values (5.0 and 4.5). The extraction ...
Nonlinear response and axisymmetric wave propagation in functionally graded soft electro-active tubes
(Elsevier, 2020-10-02)
Soft electro-active (SEA) materials can be designed and manufactured with gradients in their material properties, to modify and potentially improve their mechanical response in service. Here, we investigate the nonlinear ...
Numerical study on the minimum ignition energy of a methane-air mixture
(Elsevier, 2020-09-28)
In this paper, a semi-detailed mechanism is used to calculate the minimum ignition energy (MIE) of methane-air mixtures, with all calculations conducted using ANSYS Fluent software. Ignition behaviors between success and ...
A kinetics and dynamics study on the auto-ignition of dimethyl ether at low temperatures and low pressures
(Elsevier, 2020-09-14)
Though the combustion chemistry of dimethyl ether (DME) has been widely investigated over the past decades, there remains a dearth of ignition data that examines the low-temperature, low-pressure chemistry of DME. In this ...
Discovery and recovery of an exceptional accumulation of carboniferous echinoids at Hook Head, Wexford
(Royal Irish Academy, 2022-09-30)
Geoconservation is a burgeoning area of activity within the Earth sciences and the preservation of significant fossil finds remains crucial for the advancement of palaeontological knowledge and protection of geoheritage. ...
The invisible barrier to safe textile recycling
(Frontiers Media, 2022-06-14)
Presence of certain chemical additives (e.g. halogenated flame retardants, perfluoroalkyl substances, and phthalates) could hinder textile recycling operations as their presence renders end-of-life materials as “hazardous” ...
Quantitative analysis of weakly bound insulin oligomers in solution using polarized multidimensional fluorescence spectroscopy
(Elsevier, 2020-09-08)
Being able to measure the size and distribution of oligomers in solution is a critical issue in the manufacture and stability of insulin and other protein formulations. Measuring oligomers reliably can however be complicated, ...
Development of a 5-component gasoline surrogate model using recent advancements in the detailed H2/O2/CO/C1-C3 mechanism for decoupling methodology
(Elsevier, 2020-08-17)
In the present work, a 5-component gasoline surrogate chemical kinetic mechanism has been developed and
validated. The first novelty of this mechanism is that a recently advanced H2/O2/CO/C1 detailed sub-mechanism
is ...
The awarding of the first honorary Doctor of Science by the Queen's University in Ireland to William King – a journey of scientific curiosity
(Royal Irish Academy, 2020)
William King (1809 86) was the founding Professor of Mineralogy and Geology at Queen s College Galway (QCG), one of three regional colleges opened in 1849 to provide secular university-level education in Ireland. King came ...
