While we cannot directly observe them, every galaxy has its own halo of dark matter, on which familiar, visible matter hangs. Our solar system orbits the centre of our galaxy, while Earth orbits the Sun. As we do this, our motion through the Milky Way’s halo of dark matter creates the Headwind Effect. Dr Grace Lawrence asked whether this Headwind exhibits “gusts” of higher intensity.
It’s not uncommon to have “four seasons in one day” in Melbourne. Our variable weather patterns are driven by conditions moving from west to east and, to some extent, from the Southern Ocean to Australia. These variables control cloud formation and, just like following a cake recipe, change in flavour and form depending on the ingredients you put in.
Industry 4.0 is the next industrial revolution, utilising digitalisation to create a smarter, self-correcting manufacturing processes. Bringing this new industrial age together with science is Professor Bronwyn Fox, winner of the 2020 Medal for Excellence in Scientific Research. Her journey with carbon fibre production saw the develop a more efficient fabrications process for composite materials, and also had her involved with Quickstep and their new composite material process. At the time a small start-up, Quickstep is now the largest Australian independent manufacturer of composite materials, and Bronwyn took this entrepreneurial mindset and founded Deakin University’s Carbon Nexus facility. Professor Bronwyn Fox continued her research into renewable carbon fibre and established yet another facility – the National Industry 4.0 Testlab – which focuses on 3D printing of composite materials.
What does DNA, snowflakes and the hydrophobic effect have in common? They are all example of molecular self-assembly! Inspired by this process of nature, Dr Nisa Salim used attractive and repulsive forces to influence molecules to interact, and in doing so created an array of nanostructures capable of becoming solar cells, drug delivery systems, and in her newest venture – manipulating carbon fibre to be stronger than steel, lighter than aluminium and even electrically conductive! For her work in carbon manufacturing, Dr Nisa Salim was awarded the 2020 Phillip Law Postdoctoral Award for the Physical Sciences and explains how a nature-inspired approach to manufacturing can be the key to many issues facing our time – from climate control, water management and even high speed travel.
With Dr Rajesh Ramanathan, we encounter a special example of a scholar exploring the knowledge base from traditionally separate field of scientific inquiry. First trained as a biologist, Rajesh combined his PhD work in materials science to consolidate expertise across the chemical, physical and biological sciences, enabling him to develop and contribute to research projects across disciplinary boundaries, leading work in the exciting new field of nanobiotechnology.
