Carla Perez-Martinez, Junior Research Fellow in Chemistry, recently gave a keynote talk at the Conference of the International Association of Colloid and Interface Scientists.
Dr Perez-Martinez is a postdoctoral researcher in the group of Professor Susan Perkin, Fellow and Tutor in Chemistry at Trinity. She studies the fundamental properties of liquids at the molecular scale by performing experiments in the surface force balance.
At the conference, in Rotterdam, Dr Perez-Martinez presented work from her research group, revealing unexpected behaviour in concentrated electrolytes (e.g. salt water near the point of saturation). The interactions in these systems span much longer distances than anticipated by classical theories. In collaboration with Dr Alexander Smith, post-doctoral researcher at the University of Geneva, and Dr Alpha Lee, Winton Fellow at Cambridge University, a new scaling argument and theory has been proposed to describe these observations.
A paper summarising the experimental results and theory has also been published in Physical Review Letters. These results should be useful in the design of batteries and other electrochemical devices, in biological scenarios and in colloid science.
Dr Perez-Martinez ’s travel was supported by Trinity College.
