Tighe CJ, Maraj MP, Richardson SM, 2021, Sharing good practice in process safety teaching, Education for Chemical Engineers, Vol: 36, Pages: 73-81, ISSN: 1749-7728

The teaching of safety is one of the most important and transferrable subjects in the undergraduate chemical engineering curriculum. However, whilst different institutions have a broadly similar approach to educating students in core topics such as transport processes, approaches to safety teaching are somewhat more variable. This paper describes, analyses and reflects on our approach to safety teaching. It was found that not only are the requirements for accreditation of the degree programme by the Institution of Chemical Engineers (IChemE) met, but the majority of the IChemE Safety Centre’s (ISC) recommendations are also covered. Student feedback on the 3rd year Safety and Loss Prevention (S&LP) module showed that the course has been consistently well received by the students, pointing to good course structure and coherence being a significant factor. Analysis of the outcomes of the 2020 final examination for S&LP, using Bloom’s taxonomy, supported existing plans to change the mode of assessment of S&LP to a significant coursework project. Finally, plans for a future revision of the S&LP module are presented to serve as one exemplar of good practice in safety teaching, which not only meets the requirements of the accrediting body and industry, but is also enjoyed by students.

Ashley AE, Fuchter MJ, Tighe C, Allcock N, Scott D, Sapsford Jet al., 2018, Direct reductive amination of carbonyl compounds catalyzed by a moisture tolerant Tin (IV) Lewis acid, Advanced Synthesis and Catalysis, Vol: 360, Pages: 1066-1071, ISSN: 1615-4150

Despite the ever-broadening applications of main-group ‘frustrated Lewis pair’ (FLP) chemistry to both new and established reactions, their typical intolerance of water, especially at elevated temperatures (>100 °C), represents a key barrier to their mainstream adoption. Herein we report that FLPs based on the Lewis acid iPr3SnOTf are moisture tolerant in the presence of moderately strong nitrogenous bases, even under high temperature regimes, allowing them to operate as simple and effective catalysts for the reductive amination of organic carbonyls, including for challenging bulky amine and carbonyl substrate partners.

Tighe CJ, Twigg MV, Hayhurst AN, Dennis JSet al., 2016, The kinetics of oxidation of Diesel soots and a carbon black (Printex U) by O2 with reference to changes in both size and internal structure of the spherules during burnout, Carbon, Vol: 107, Pages: 20-35, ISSN: 0008-6223

The rates of oxidation of two soots, produced from burning either ultra low sulphur Diesel or biodiesel in an engine, were measured at 450–550 °C, with oxygen concentrations of 2.7–24.4 vol%; Printex U was also studied. These carbons were first heated in argon to remove any volatile material; the resulting particles were found to burn in two stages. An initial, fast, transient reaction consumed almost 20% of the carbon in a soot particle. The rates of oxidation, during the second part of burnout were consistent with a model assuming these soots are comprised of porous spherules, which burn throughout their interiors. The overall rates in this second stage of burning were half-order with respect to O2, with an apparent activation energy of 145 ± 8 kJ mol−1. For the two Diesel soots, [CO2] and [CO] in the off-gases decreased, whilst the carbon burned, but the rate of oxidation of Printex U increased to a second maximum. This was consistent with the spherules in this carbon having pores, which grew and intersected, whilst the carbon was consumed. Thus the interiors of spherules of both Diesel soots and Printex U must have been accessible to O2, whilst they burned.

A high performance vanadium-doped LiFePO4 (LFP) electrode is synthesized using a continuous hydrothermal method at a production rate of 6 kg per day. The supercritical water reagent rapidly generates core/shell nanoparticles with a thin, continuous carbon coating on the surface of LFP, which aids electron transport dynamics across the particle surface. Vanadium dopant concentration has a profound effect on the performance of LFP, where the composition LiFe0.95V0.05PO4, achieves a specific discharge capacity which is among the highest in the comparable literature (119 mA h g−1 at a discharge rate of 1500 mA g−1). Additionally, a combination of X-ray absorption spectroscopy analysis and hybrid-exchange density functional theory, suggest that vanadium ions replace both phosphorous and iron in the structure, thereby facilitating Li+ diffusion due to Li+ vacancy generation and changes in the crystal structure.

A strategy for fabrication of solid oxide fuel cell anodes with improved porosity and lower sintering temperatures by impregnation of nanoparticle-containing porous scaffolds of ceria-gadolinia (CGO) has been developed. The CGO scaffolds are fabricated using a screen-printed ink containing nanoparticles and commercial particles of CGO and polymeric pore formers. Scanning electron microscopy and in situ ultra-small angle X-ray scattering show that incorporation of nanoparticles increases the porosity by allowing a reduction in sintering temperature. Electrochemical characterisation of symmetrical cells shows that the cells sintered at 1000°C possess similar electrode polarisation compared to those sintered at 1300°C. Button cell testing showed that reducing the sintering temperature produced cells which perform better at 700°C and below in hydrogen, and performed better at all temperatures using syngas. This approach has the potential to allow the use of a wider range of nanomaterials, giving a finer control over microstructure.

Computational fluid dynamics is applied to a comparative study of a counter-current reactor and a confined jet reactor for continuous hydrothermal flow synthesis of nanomaterials under supercritical water conditions. The fluid flow and heat transfer variables including velocity and temperature profiles in both reactor configurations are simulated using ANSYS Fluent package. The tracer concentration profiles are also modelled via solving species equations from which the mixing behaviour in the reactors is investigated. The predicted temperatures are found to be in good agreement with experimental data. The simulation also provides suggestions to improving the reactor designs and process control. © 2012 IFAC.
