Dr Neeraj Sharma
Staff Profile
Role at ANSTO
Neeraj joined the Bragg Institute at ANSTO in September 2009 as a postdoctoral research fellow in the energy project. He utilises neutron scattering techniques to investigate crystalline components in batteries, with a particular emphasis on Li-ion batteries. A major goal of his project is to improve these types of batteries by providing a clearer understanding of what happens to the materials inside them.
Expertise
His areas of expertise include neutron and synchrotron X-ray scattering, synthetic solid-state chemistry, scanning electron microscopy and physical property measurements.
Neeraj's Ph.D. work focused on the synthesis, structural characterisation and physical properties measurements of transition metal doped bismuth oxides. During his Ph.D., Neeraj carried out specialised synthesis at the University of Auckland, New Zealand, conducted X-ray and neutron scattering experiments at major international facilities world-wide and undertook conductivity measurements at the University of Aveiro, Portugal.
Qualifications and achievements
