Role within the Centre

Ruhamah Yunis is a chemist with experience from designing, synthesizing and purifying ionic liquids, organic ionic plastic crystals, metal complexes, corrosion inhibitors, polymerized ionic liquids and many more fields for vast applications. She also has scale-up experience, from synthetic protocol up to 100g with purity above 99.9%. Within QUT’s Centre of Materials Science, Ruhamah will be using her synthetic chemistry skills to design and synthesize macromolecules with a photosensitive unit under the supervision of Dr. Anja Goldman, Prof. Christopher Barner-Kowollik and Prof. Dmitri Golberg. This macromolecule will be studied by new double aberration-corrected, 30-200 kV high-resolution Transmission Electron Microscopy (TEM) to study the effect of light change on the macromolecule’s morphology. Classically, nanostructured macromolecular morphologies have been static and observed at the several nm level. This project will be the first real-time observation of quasi-atomistic transformations in macromolecules by light. This project will open collaborations across Australia and worldwide. All equipment and facilities required for this project are located within QUT at the Centre of Materials Science.

Short Biography

Ruhamah graduated with a degree in BS(Hons) and MS in chemistry from the University of the Punjab, Lahore, Pakistan. She served as a Chemistry Lecturer at University of the Gujrat (2008-2009) and Forman Christian College (2009-2010) in Pakistan, where she was involved in teaching and research. She graduated with a PhD (2010-2015) degree in Chemistry from University of Canterbury, New Zealand with a UC Doctoral Scholarship. Ruhamah joined Deakin university, Australia in 2015, as an Associate Research Fellow where she was involved in designing, synthesizing and purifying ionic liquids, organic ionic plastic crystals, metal complexes, inorganic salts, corrosion inhibitors and polymerized ionic liquids, for lithium and sodium battery electrolytes. She was successful in attaining two Deakin Universities internal grants. In May 2020 Ruhamah joined QUT’s Centre of Materials Science as an Early Career Researcher.
