Quantum computing closer with chemistry breakthrough
Quantum computing is a leap closer to reality with a chemistry breakthrough demonstrating it is possible for nanomaterials to operate at room temperature rather than at absolute zero experienced in deep space (-273C).
The key to quantum computing could be a simple as burning the active ingredient in moth balls; using this method, the holy grail of quantum computing – the ability to work in ‘real-world’ room temperatures – has been demonstrated by an international group of researchers, combining chemistry with quantum physics.
Co-led by Dr Mohammad Choucair – who recently finished a University of Sydney research fellowship gained as an outstanding early career researcher in the School of Chemistry – the 31-year-old has been working with collaborators in Switzerland and Germany for two years before the breakthrough.

Molecular polymer brushes in nanomedicine
Dr Markus Muellner's recent article on brush nanomedicine has been highlighted in Wiley’s Materials Views. Read more.
Summary: In nanomedicine, we apply nanotechnology to solve persevering issues in prevention, treatment and diagnosis of common diseases. Within this field, polymeric nanoparticles are hot contenders of delivering novel and modular solutions to overcome these issues. Amongst widely used polymer nanoparticles, such as micelles and polymersomes, elaborate polymer architectures are experiencing increasing interest. Molecular polymer brushes (also known as cylindrical polymer brushes or molecular bottlebrushes) are particularly intriguing. Despite being only one giant macromolecule, these molecular heavyweights can easily adopt the size of colloids. This places these unique polymer constructs in a niche between nanoparticles and polymer coils.
Throughout the past decade, these remarkable materials have witnessed an ever-growing interest from many disciplines. The modular build-up of molecular polymer brushes allows for tailoring size and composition simply via polymerisation. Thus, these materials are very appealing in addressing problems where precise tuning of functionality and physicochemical properties is of high importance. Originally considered a molecular playground predominately for synthetic polymer chemists; nowadays, these elaborate nano-constructs find application in many fields of science and engineering.

Professor Thomas Maschmeyer raises $21m in two months
"University of Sydney professor Thomas Maschmeyer has not needed any of the new government help on offer for universities to commercialise inventions, raising $21 million in the last two months to spin out two technologies, one of which could form the basis for the largest biodiesel project in the world.
In April, UK energy investor Armstrong Energy paid $11 million for a commercial prototype of a house whose walls will contain batteries invented by Maschmeyer. The University of Sydney (USyd) spun out the intellectual property in return for equity in a startup named Gelion. The business is developing batteries made with nano-structured gels which claim better performance than lithium ion batteries in their charging and discharging speed, as well as being smaller, safer, more durable and cheaper."

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.
