The adsorption structure of truxenone on Cu(111) was determined quantitatively using normal-incidence X-ray standing waves. The truxenone molecule was found to chemisorb on the surface, with all adsorption heights of the dominant species on the surfa...

Experimental measurement and prediction of ionic liquid ionisation energies (2021)
Journal Article
Seymour, J. M., Gousseva, E., Large, A. I., Clarke, C. J., Licence, P., Fogarty, R. M., Duncan, D. A., Ferrer, P., Venturini, F., Bennett, R. A., Palgrave, R. G., & Lovelock, K. R. J. (2021). Experimental measurement and prediction of ionic liquid ionisation energies. Physical Chemistry Chemical Physics, 23(37), 20957-20973. https://doi.org/10.1039/d1cp02441h

Ionic liquid (IL) valence electronic structure provides key descriptors for understanding and predicting IL properties. The ionisation energies of 60 ILs are measured and the most readily ionised valence state of each IL (the highest occupied molecul...

Pre-existing asthma as a comorbidity does not modify cytokine responses and severity of COVID-19. Allergy, Asthma and Clinical Immunology, 17, Article 67. https://doi.org/10.1186/s13223-021-00569-8

Background
A significant portion of COVID-19 sufferers have asthma. The impacts of asthma on COVID-19 progression are still unclear but a modifying effect is plausible as respiratory viruses are acknowledged to be an important trigger for asthma exa...

Angewandte Chemie International Edition, 60(30), 16561-16567. https://doi.org/10.1002/anie.202104075

We assess the crucial role of tetrapyrrole flexibility in the CO ligation to distinct Ru-porphyrins supported on an atomistically well-defined Ag(111) substrate. Our systematic real-space visualisation and manipulation experiments with scanning tunne... Read More about Conformational Control of Chemical Reactivity for Surface‐Confined Ru‐Porphyrins.
