Georgina’s poster was titled, ‘Peptide-based tunable molecular wires’. The full list of students who competed in the poster competition can be found online , with her entry at #252 under section (7) Biological.

 

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.

 

Inter-faculty BioFocus Research Conference at Macquarie

blog-image15 December 2015:

Mid December saw the successful undertaking of the annual Inter-faculty BioFocus Research Conference at Macquarie University, with three CNBP aligned researchers key organisers of the event – Lindsay Parker, Annemarie Nadort and Varun Sreenivasan.

The annual conference provides a platform for the multidisciplinary community at Macquarie University to present and communicate research, discuss research outcomes and facilitate interdisciplinary collaborations spanning the fields of of biomedical sciences, biomedical engineering, physics, chemistry and medicine.

It also allows Higher Degree Research (HDR) students to practice their oral and poster presentation techniques in front of an audience, with a professional jury giving feedback.

Highlights of the conference included:

– 120 registered attendees (50% more than previous years)
– 2 plenary talks, 1 invited talk and 13 contributing talks (7 of which were from HDR students)
– 22 poster presentations
– 4 awarded prizes for outstanding oral and poster presentations to HDR students
– interest and financial support from industry, including attendance and commercial display from sponsors Merck Millipore and ThermoFischer. Industry supported poster prizes.

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.

Wyatt Roy visits CNBP at RMIT

cnbplogosquare110 December 2015:

The Federal Member for Longman and Assistant Minister for Innovation Wyatt Roy, along with the Vice Chancellor of RMIT Martin Bean, toured the three new CNBP optics laboratories today.

They were shown CNBP’s custom confocal microscope setups including the cryostat which can be use to study light emitting properties of fluorescent nanomaterials from +70 deg C to -269 deg C. Also shown were autofluorescence images of a mouse oocyte (egg).

CNBP CIs Brant Gibson and Andrew Greentree briefly discussed the recently announced Australian Government’s Innovation Statement with Minister Roy and future commercial translation opportunities of CNBP technologies e.g. a ‘clinical version’ of one of the Centre’s custom confocal microcopes.

During the tour of the facilities, Minister Roy also met and chatted with many of the RMIT CNBP post docs and students.
