Clay–oil interactions play a critical role in determining the wettability of sandstone oil reservoirs, which, in turn, governs the effectiveness of enhanced oil recovery methods. In this study, we have measured the adhesion between –COOH functional g...

Mineral Surface Chemistry Control for Origin of Prebiotic Peptides (2017)
Journal Article
Erastova, V., Degiacomi, M. T., Fraser, D., & Greenwell, H. C. (2017). Mineral Surface Chemistry Control for Origin of Prebiotic Peptides. Nature Communications, 8, Article 2033. https://doi.org/10.1038/s41467-017-02248-y

Some seventy years ago, John Desmond Bernal proposed a role for clays in the origin of life. While much research has since been dedicated to the study of silicate clays, layered double hydroxides, believed to be common on the early Earth, have receiv...

Analytical solution for clay plug swelling experiments (2017)
Journal Article
Mathias, S., Greenwell, H., Withers, C., Erdogan, A., McElwaine, J., & MacMinn, C. (2017). Analytical solution for clay plug swelling experiments. Applied Clay Science, 149, 75-78. https://doi.org/10.1016/j.clay.2017.07.021

Clay swelling experiments frequently involve monitoring the one-dimensional displacement with time of an initially dry clay plug as it imbibes water from a supply at its base. This article presents a new analytical solution for interpreting such expe... Read More about Analytical solution for clay plug swelling experiments.

Translocation of isotopically distinct macroalgae: a route to low-cost biomonitoring? (2017)
Journal Article
Gröcke, D., Racionero-Gómez, B., Marschalek, J., & Greenwell, H. (2017). Translocation of isotopically distinct macroalgae: a route to low-cost biomonitoring?. Chemosphere, 184, 1175-1185. https://doi.org/10.1016/j.chemosphere.2017.06.082

Nitrogen stable isotope ratios (δ15N) in macroalgae are often used to identify sources of nitrogenous pollution in fluvial and estuarine settings. This approach assumes that the macroalgal δ15N is representative of the sources of the pollution averag...
