I am an applied mathematician and physical chemist with broad research expertise in nonlinear and complex dynamical systems. My ARC Future Fellowship is entitled - “The charXive challenge and the clean coal quest: thermokinetic principles and methods for capturing and sequestering carbon dioxide." The next 50 years will be the era during which the world's fuels must be decarbonised. Endex thermoreactive principles, which I co-invented in the mid 1990s, are providing a novel technology for separating carbon from fuels and flue gases. I am developing a suite of Endex decarbonation technologies in collaboration with an industry partner, Calix Ltd, and with collaborators from Imperial College London, the University of Leeds, and CanMet Energy. Endex principles also underpin carbon capture from the atmosphere and have been used by nature for millions of years: the mechanism behind thermal decomposition of biomass is an Endex thermochemical oscillator that governs the distribution of carbon between the global solid black carbon reservoir and the atmospheric CO2 reservoir. My research is elucidating this mechanism.

    http://anu.academia.edu/RowenaBall. Summary: Two published examples of incorrect and dangerous thermal runaway criteria are exposed. Stability theory has been used by chemical engineers to assay reactive thermal hazard for sixty years - why has this knowledge been completely ignored by the authors of those works? They claim to specify thermal 'safety' criteria but, to the contrary, they are seriously putting human lives at risk.
