$11m UK investment in nano start-up boon for eco energy
An ambitious plan to make commercially viable, nanostructured, gel-based batteries to lead the renewable electricity revolution is closer to becoming a reality, with the multimillion-dollar investment by the UK’s major utility-scale solar energy company into a pioneering University of Sydney start-up.
“The idea is to build houses with batteries inherently included as part of their structure, ready to take advantage of rapidly improving, solar energy technology and also to serve as a buffer for the grid, enabling an ever greater share of renewables to be connected, while grid stability is maintained” Professor Maschmeyer, from the School of Chemistry said.

K computer provides new insights into fullerenes
The University of Sydney in collaboration with a group of Scientists from the RIKEN Advanced Institute for Computational Science (AICS) in Japan have made use of the tremendous power of the K computer to provide new insights into the properties of fullerenes. Dr Bun Chan from the School of Chemistry at Sydney University and author of the study describes the important contribution this study has made to the study of nanomaterials. Read more.
Superhydrophobicity is child’s play
A team of chemical researchers from The University of Sydney have developed a new robust nanostructured material that is extremely repellent to water droplets due to its highly wrinkled surface.
The team in the School of Chemistry, led by A/Prof Chiara Neto, developed a surface with a special roughness, combining micro-scale and nanoscale features, which mimics the surface structure of the leaf of the Sacred lotus. Droplets of water placed on the Sacred lotus leaf bead up in a spherical shape, a sign that the petal is highly water-repellent; the droplets roll off the petals very easily, and in doing so remove contaminants and dust from the surface. The mechanism behind this behaviour is due to the special surface structure of the lotus leaf, made up of micrometric bumps covered with even smaller nanometric ones, engineered to trap air on the surface and therefore repel water.

Gold nanoparticles riddle solved – offering medical hope
Products based on nanoparticles are not new, with gold nanoparticles used by the Ancient Egyptians to make paints lasting for millennia - but they are promising to deliver a wide range of new medical imaging and treatment technologies.
An international group of researchers including the University of Sydney have solved the riddle in work published today in The Proceedings of the National Academy of Science of the United States of America. It is all in the glue that binds the surface of the gold nanoparticles to keep potentially destructive chemicals out of contact range. Read more.
Research raises concerns over long-term use of chromium diet pills
Concerns have been raised over the long-term use of nutritional supplements containing chromium, after an Australian research team found the supplement is partially converted into a carcinogenic form when it enters cells.
The team, led by Professor Peter Lay from the University of Sydney’s School of Chemistry and Dr Lindsay Wu, now with UNSW’s School of Medical Sciences, travelled near to Chicago to Argonne National Laboratory to perform the experiments in collaboration with colleagues at Argonne’s, the Advanced Photon Source, a US Department of Energy Office of Science User Facility that generates ultra-bright, high-energy x-rays.
