Sylvia finished her PhD from Bangalore University, Bangalore, India where her research focus was on the study of defects and polymorphism in layered anionic clays. After this, she got a Schlumberger Faculty for the Future Award to pursue a Postdoc at the University of Cambridge in Prof. Clare P. Grey’s group where her research was focussed on studying the mechanistics of sulfide based battery conversion materials with a host of techniques including solid state NMR, X-ray Diffraction, Total Scattering techniques and X-ray Absorption Spectroscopy. She is currently a Postdoc at the I18 Microfocus Spectroscopy Beamline at Diamond Light Source Ltd where her research is on studying the mechanisms of nanoparticle nucleation and growth using operando X-ray Absorption Spectroscopy.

Title – Understanding the mechanism of nucleation of platinum nanoparticles using operando X-ray Absorption Spectroscopy coupled with Microfluidics
Outline – The aim of my research is to study the mechanisms underlying nanoparticle nucleation by a continuous flow process using operando X-ray Absorption Spectroscopy (XAS) coupled with microfluidics. In contrast to a batch synthesis, a continuous flow device allows for rapid and efficient mixing of precursors and fine control over the synthesis parameters such as concentration, flow rate and temperature. Control of the spot size of the microfocus beam at Diamond beamline I18 coupled with control of the flow rate can allow for microsecond time resolution as the spatial distance along the length of the channel can be correlated with time of the reaction after the mixing point. The objectives of the study include identifying the intermediate species formed during the nucleation process using XAS.
