Samia Said


PhD Researcher


Samia was born and raised in London, and left the nest to go to the uni of Manchester to complete a degree Chemistry. After that she attempted to get a real job in London, but quickly found herself back at university for a Masters in chemical engineering at Imperial college. Since then, wanting to contribute to a more sustainable future, she joined the EIL group at UCL for her PhD project working on developing new materials for sodium ion batteries to improve their performance. Outside work you can find her either cooking, swimming or out with friends.


Two dimensional (2D) materials with atomically thin layers, have gained traction and have been widely developed for different applications, including energy storage systems. These include the graphene, metal chalcogenides, metal oxides and phosphorene. These promising materials, however are not well established and an in-depth understanding, across multiple length scales, of the correlations between electrochemical performance and structural, chemical, and mechanical changes, of these materials is still required in order to apply them into energy storage systems.

A powerful tool that allows visualisation of nanoscale processes of the electrode/electrolyte interface is, in situ and operando Electrochemical-Atomic Force Microscopy (EC-AFM). Unlike other in situ and operando techniques, EC-AFM can provide nano-spatially resolved results, whilst maintaining the integrity of the sample, in real battery environments. This is incredibly important as it enables the probing of key phenomena taking place at the surface of electrode materials that determine its overall performance. Samia will characterising the interfacial properties of these promising 2D (and 1D) materials, by utilising in situ and operando EC-AFM as anode materials for sodium ion batteries.
