Grimwade Prize in Industrial Chemistry

Saturday, 28 February 2015 - 11:00am

The Faculty of Science 2013 Grimwade Prize in Industrial Chemistry has been awarded to Assoc Prof Paul Donnelly for his research on "Medicinal Chemistry: New Agents for the Diagnosis and Treatment of Alzheimer’s Disease and Cancer". The Grimwade Prize was established in 1905 by the Honourable Frederick Sheppard Grimwade, a drug wholesaler and part-owner of Felton, Grimwade & Co. The company later became Felton, Grimwade and Bickfords Pty Ltd, the largest drug wholesaler in Victoria. See list of prizewinners.

Front-cover article in J Comp Chem

Saturday, 28 February 2015 - 10:15am

Dr Lars Goerigk, in collaboration with Dr Amir Karton of UWA, has shown by using highly accurate thermochemical protocols (called Wn-F12) that a widely used and popular quantum chemical approach – the CBS-QB3 composite method – produces unusually large deviations for pericyclic reaction barrier heights. This unexpected finding has a significant impact on studies carried out for the assessment of density-functional-theory methods and on their application to better understand experimental results. The examples discussed in this article are a reminder to be cautious in the application of CBS-type composite methods in similar situations Journal of Computational Chemistry 2015, 36, 622-632.

Chemistry student at Global Young Scientists Summit 2015

Thursday, 12 February 2015 - 10:30am

Nick Kirkwood, PhD Chemistry student in the Mulvaney laboratory, Bio21, attended the Global Young Scientists Summit 2015, Singapore, in January. “It was a very inspiring experience indeed - a unique opportunity to learn from highly distinguished invited Nobel Laureates and other speakers and engage with a very enthusiastic and innovative group of early career researchers from a very broad range of scientific disciplines,” he said. Organised by the National Research Foundation of Singapore, the event brought together 239 young researchers scientists from all over the world. The multidisciplinary summit – covering a range of topics from physiology, medicine, chemistry, physics, mathematics, computer science & engineering – featured 20 eminent speakers, including 12 Nobel Laureates.

Improved solar panels & printed electronics

Thursday, 15 January 2015 - 6:30pm
New and improved solar panels could result from the discovery of a new liquid crystal material, making printable organic solar cells better performing. Work published in Nature Communications could lead to vastly improved organic solar cell performance. Lead author, David Jones of the School of Chemistry, said these cells will be easier to manufacture, with the new crystals now able to work in cells that are double in thickness on the previous limit of 200 nm. 
"It had been theorized that a certain group of nematic liquid crystals would provide excellent electronic properties – as well as being printable – and, therefore, have been sought for a long time,” said Dr Jones. “With this research, we have shown for the first time these high performing materials.”
The research was conducted with international researchers in Singapore, China and Germany, and received funding from the Victorian Organic Solar Cell Consortium, and the Australian Centre for Advanced Photovoltaics.

Beer and bread yeast-eating bacteria aid human health

Thursday, 8 January 2015 - 6:00pm

Bacteria that have evolved to eat their way through yeast in the human gut could inform the development of new treatments for bowel diseases. Publishing their findings in Nature, 517:165 (8 Jan 2015), the international research team* say discovery of this process could accelerate development of prebiotic medicines to help people suffering from bowel problems and autoimmune diseases. Scientists from UK, Australia, Canada, USA & Belgium have unraveled how Bacteroides thetaiotaomicron, a dominant member of the human microbiome, has learned to feast upon difficult to break down complex carbohydrates called yeast mannans.

"Bacteroides thetaiotaomicron is an important part of our microbiota, the community of bacteria that live within us. By consuming carbohydrates that we can’t, which they convert to short-chain fatty acids that they secrete into our distal gut, these bacteria establish a symbiosis that nourishes the cells that line our gut wall and provide important immune signals that establish a healthy immune response.” says Assoc. Prof. Spencer Williams, School of Chemistry, who contributed to the work.
