The best-known theory accounting for metal-alginate complexation is the so-called “Egg Box” model. In order to gain greater insight into the metal-saccharide interactions that underpin this model, the coordination chemistry of the corresponding monom...

Sodium salts of the algal uronic-acids, d-mannuronic acid (HManA) and l-guluronic acid (HGulA) have been isolated and characterised in solution by nuclear magnetic resonance (NMR) spectroscopy. A suite of recently-described NMR experiments (including... Read More about Solution-state behaviour of algal mono-uronates evaluated by pure shift and compressive sampling NMR techniques.

Ketone Formation via Decarboxylation Reactions of Fatty Acids Using Solid Hydroxide/Oxide Catalysts (2018)
Journal Article

A sustainable route to ketones is described where stearone is produced via ketonic decarboxylation of stearic acid mediated by solid base catalysts in yields of up to 97%, at 250 °C. A range of Mg/Al layered double hydroxide (LDH) and mixed metal oxi... Read More about Ketone Formation via Decarboxylation Reactions of Fatty Acids Using Solid Hydroxide/Oxide Catalysts.

In this work, Pseudomonas cepacia lipase immobilized on cellulosic polyurethane was used as a catalyst for biodiesel production via trans-esterification reactions in order to provide cost-effective methods of enzyme recycling. The efficacy of the imm... Read More about Biodiesel production via trans-esterification using Pseudomonas cepacia immobilized on cellulosic polyurethane.

Changes in higher heating value and ash content of seaweed during ensiling (2016)
Journal Article

A problem in the use of macroalgae for biofuel is that harvesting of seaweed is generally seasonal, and there is a need to preserve and store seaweed to supply year-round production processes. Ensiling is a widely used preservation method in agricult... Read More about Changes in higher heating value and ash content of seaweed during ensiling.
