Abstract

Metal oxide semiconductor nanoparticles and nanowires have demonstrated unique properties that allow fabrication of highly performing batteries, gas sensors, chemical sensors, photodetectors, solar cells and functional coatings, to name a few. The synthesis of these metal oxide nanoparticles by flame spray pyrolysis (FSP) is a newer but already well-developed process in terms of product diversity. Many elements of the periodic table can be turned into oxides, salts, or even metal nanoparticles in laboratory-scale reactors with production rates of a grams per hour. The major advantages of this method are the single-step process, the controllability of primary particle size (12 to 200 nm), ultra-high porosity of the fabricated film (up to 98%), and the possibility of in situ deposition of noble metal catalysts. This process can also be used to deposit a catalytic filtering layer for controlling the gas selectivity.

These ultraporous nanostructured films could be potentially utilised in sensing devices including gas sensors (early detection of diseases through analysing human breath, detecting poisons gases/explosive materials), photodetectors (measuring UV dosage absorbed by skin to prevent skin cancer, IR detectors) as well as other applications including super-hydrophobic/super-hydrophilic coatings, water splitting catalysis for hydrogen production, biomimetic coatings and so on

Biography

Dr Noushin Nasiri has received her Bachelor and Master of Engineering in Materials Engineering from the University of Tehran in Iran and then pursued her research at the Nanotechnology Research Laboratory of the Australian National University (ANU) where she received her PhD in Nanotechnology, in 2017. Then, she took a postdoctoral position at University of Technology Sydney, before joining Macquarie University in late 2018. She is currently Head of the NanoTech Laboratory at the School of engineering, Macquarie University, leading a group of 2 PhDs, 4 Masters of Research and 4 Honours students, working on design, synthesis and fabrication of nanostructured metal oxide films/nanoparticles for health, energy and environmental applications.

She is a passionate science communicator and her research has been recognized with several prestigious invited talks including TEDx Sydney Salon (2017), ABC Ockham’s Razor (2018), TEDx Macquarie University (2019) and TEDx Bligh Street (2020). In 2017, she was selected as one of the top 20 young scientists under the age of 40 by Inter Academy Partnership (IAP) to attend the World Science Forum in Jordan. She is the winner of 2019 NSW Tall Poppy Award, 2017 AMP Amplify Ignite and 2016 Famelab Australia Grand Final (runner up).
