New sensor to aid IVF

Malcolm Purdey Low Res Edit 007517 December 2015:

CNBP researcher Malcolm Purdey is lead author on a new paper published in the Journal Sensors. The paper reports the first single optical fibre tip probe for concurrent detection of both hydrogen peroxide (H2O2) concentration and pH of a solution.

The paper is titled “A Dual Sensor for pH and Hydrogen Peroxide Using Polymer-Coated Optical Fibre Tips” and is fully accessible online.

A CNBP media release on this research finding is also available from the CNBP web site.

 

Future Fellowship awarded

Alfonso Garcia-Bennett (2)16 December 2015:

Congratulations to CNBP Research Fellow Dr Alfonso Garcia-Bennett, who today was awarded $674,352.00 under the ARC Future Fellowships scheme for 2016.

The Fellowship which provides funding for four years, will allow Alfonso to develop his research in determining how the intrinsic physico-chemical properties of nanoparticles translate into extrinsic biological properties through their interaction with physiological proteins in the body. This enabling efficient cellular targeting of pharmaceutical drugs in the body.

Further information on the Future Fellowships scheme, the Fellowships awarded and Alfonso’s project can be found at the Australian Research Council (ARC) web site, online.

Prof Calum Drummond, RMIT Deputy Vice-Chancellor Research and Innovation and Vice-President and CNBP Advisory Board Member, has been awarded the HG Smith Memorial Medal from the Royal Australian Chemical Institute (RACI) for his ability to fundamentally advance a field of research in chemical science, as evidenced by 10 years of publications.

The annual medal is given to the person deemed to have contributed the most to a particular field of chemistry in Australia.

Further information on Prof Drummond’s award can be found on the RMIT web site.

Drawing tubular fibres

Heike Ebendorff Low Res Edit 018015 December 2015:

CNBP researchers A/Prof Heike Ebendorff-Heidepriem and Dr Herbert Foo feature in this latest paper published in Optical Materials Express – ‘Drawing tubular fibres: experiments versus mathematical modelling.’

Abstract – 
A series of six experiments drawing tubular fibres are compared to some recent mathematical modelling of this fabrication process. The importance of fibre tension in determining the internal geometry of the fibre is demonstrated, confirming a key prediction of the models. There is evidence of self-pressurisation of the internal channel, where an additional pressure is induced in the internal channel as the fibre is drawn, and the dependence of the magnitude of this pressure on fibre tension is discussed. Additionally, there is evidence that the difference between the glass and furnace temperatures is proportional to the furnace temperature and dependent on the preform geometry.

Further paper information is available online.

Electronic transport in Si:P δ-doped wires

Daniel Drumm Low Res Edit 012211 December 2015:

‘Electronic transport in Si:P δ-doped wires’ is the latest paper by CNBP Research Fellow Dr Daniel Drumm, published in the journal Physical Review B.

Abstract – Despite the importance of Si:P δ-doped wires for modern nanoelectronics, there are currently no computational models of electron transport in these devices. In this paper we present a nonequilibrium Green’s function model for electronic transport in a δ-doped wire, which is described by a tight-binding Hamiltonian matrix within a single-band effective-mass approximation. We use this transport model to calculate the current-voltage characteristics of a number of δ-doped wires, achieving good agreement with experiment. To motivate our transport model we have performed density-functional calculations for a variety of δ-doped wires, each with different donor configurations. These calculations also allow us to accurately define the electronic extent of a δ-doped wire, which we find to be at least 4.6 nm.

Coverage: Barbara Kidman Fellowships

Barbara-Kidman10 December 2015:

University of Adelaide and CNBP researchers Dr Sabrina Heng and Dr Melanie McDowall are recipients of the Barbara Kidman Women’s Fellowship for 2016.

The Fellowship supports  female academics in enhancing and promoting their career, following time out of the workplace due to carer’s or family leave. The Fellowship is for 12 months and can be used for research support, overseas travel or professional development.

Both Sabrina and Mel were interviewed about the award, their science and their experiences in academia more generally on Radio Adelaide’s ‘Sound of Sciene’ program.

The full interview can be heard online here.

Life membership of AOS

jimpiper8 December 2015:

Prof Jim Piper, CNBP Macquarie University Node Leader has been awarded Honorary Life Membership of the Australian Optical Society (AOS) following the organisation’s annual general meeting, held in 2015.

The award recognizes Jim’s contribution to the society over many years. His signature was on the Memorandum of Association that established the AOS as an association in 1983. He took over the AOS presidency in 1984-1985, and was the recipient of the AOS W.H. (Beattie) Steel Medal – in 1997.

Also awarded life membership at the December 2015 meeting were Macquarie University’s Prof. Brian Orr and Prof. Ross McPhedran from the University of Sydney.

All continue to be involved with the AOS on an ongoing basis.

Order of merit!

sabrina24 December 2015:

CNBP’s Sabrina Heng has been awarded the Dean’s Order of Merit for the Edith Dornwell Medal for 2015.

The award recognises research excellence by a female Early Career Researcher (ECR) within the Science Faculty of the University of Adelaide.

Sabrina’s work on developing optical fiber-based, regenerable sensors for metal ions in biology, looks to facilitate early disease diagnosis.

Well done Sabrina!
