• Application of mathematical modelling to reducing and minimising energy requirement for oxygen transfer in batch stirred tank bioreactors 

  Fitzpatrick, John J.; Gloanec, Franck; Michel, Elisa; Blondy, Johanna; Lauzeral, Anais (MDPI, 2019-02-03)

  In this study, microbial kinetic and oxygen transfer modelling coupled with energy analysis was applied to investigate how manipulation and control of agitator power input and air flowrate can reduce and minimise the total ...
• Thermodynamic assessment of non-catalytic Ceria for syngas production by methane reduction and CO2 + H2O oxidation 

  Bose, Archishman; Farooqui, Azharuddin; Ferrero, Domenico; Santarelli, Massimo; Llorca, Jordi (Springer Verlag, 2019-01-31)

  Chemical looping syngas production is a two-step redox cycle with oxygen carriers (metal oxides) circulating between two interconnected reactors. In this paper, the performance of pure CeO2/Ce2O3 redox pair was investigated ...
• Four millennia of dairy surplus and deposition revealed through compound-specific stable isotope analysis and radiocarbon dating of Irish bog butters  

  Smyth, Jessica; Berstan, Robert; Casanova, Emmanuelle; McCormick, Finbar; Mulhall, Isabella; Sikora, Maeve; Synnott, Chris; Evershed, Richard P. (Springer Nature, 2019-03-14)

  Bog butters are large white or yellow waxy deposits regularly discovered within the peat bogs of Ireland and Scotland. They represent an extraordinary survival of prehistoric and later agricultural products, comprising the ...
• Assessing environmental sustainability using ecological limits expressed as mass flowrates with the inclusion of a sustainable time perspective 

  Fitzpatrick, John J.; Mullally, Brian (MDPI, 2019-09-24)

  This study explores the concept of ecological limits (ELs) for determining the sustainable extraction of natural resources and sustainable discharge of emissions. ELs are expressed as limiting mass flowrates and equations ...
• Insights from mathematical modelling into energy requirement and process design of continuous and batch stirred tank aerobic bioreactors 

  Fitzpatrick, John J. (MDPI, 2019-07-13)

  Bioreaction kinetics, oxygen transfer and energy modelling were applied to stirred tank aerobic bioreactors. This was done to investigate how key input design variables influence bioreactor size, feed and wasted substrate, ...
