Macroalgae (seaweed) has been shown to be an effective environmental indicator. We investigate the trace element chemistry of macroalgae samples from locations along the Firth of Forth and Forth Estuary in Scotland. The overall trend in elemental abu...

The osmium isotopic composition (187Os/188Os) of seawater reflects the balance of input from mantle-, continental- and anthropogenic-derived sources. This study utilizes the Phaeophyceae, Fucus vesiculosus, to analyse its Os abundance and uptake, as...

Rhenium uptake and distribution in phaeophyceae macroalgae, Fucus vesiculosus (2016)
Journal Article
Racionero-Gómez, B., Sproson, A., Selby, D., Gröcke, D., Redden, H., & Greenwell, H. (2016). Rhenium uptake and distribution in phaeophyceae macroalgae, Fucus vesiculosus. Royal Society Open Science, 3(5), Article 160161. https://doi.org/10.1098/rsos.160161

Owing to Rhenium (Re) having no known biological role, it is not fully understood how Re is concentrated in oil kerogens. A commonly held assumption is that Re is incorporated into decomposing biomass under reducing conditions. However, living macroa...

Copper(II)-mediated thermolysis of alginates: a model kinetic study on the influence of metal ions in the thermochemical processing of macroalgae (2012)
Journal Article
Rowbotham, J., Dyer, P., Greenwell, H., Selby, D., & Theodorou, M. (2012). Copper(II)-mediated thermolysis of alginates: a model kinetic study on the influence of metal ions in the thermochemical processing of macroalgae. Interface Focus, 3(1), https://doi.org/10.1098/rsfs.2012.0046

Thermochemical processing methods such as pyrolysis are of growing interest as a means of converting biomass into fuels and commodity chemicals in a sustainable manner. Macroalgae, or seaweed, represent a novel class of feedstock for pyrolysis that,...
