The deadline for submission of abstracts to the 7th Korean–Australian Rheology Conference has been extended until 22 August 2013. Those interested are urged to make best use of this opportunity.
Prof. Robert K. Prud'homme (Princeton) will be presenting a seminar on the topic
Scaleable Polymeric Nanoparticle Formation for Multifunctional Drug Delivery & Imaging
at Monash University, on Thursday, 01 August 2013, at 15:00 to 16:00. This will be held in Room S1, Building 25, at the Clayton campus.
We have developed a block-copolymer-directed, kinetically-controlled self-assembly process called Flash NanoPrecipitation (FNP) to produce 50-400 nm nanoparticles. The process involves controlling micromixing to effect supersaturations as high as 10,000 in 1.5 ms, and then controlling nucleation and growth rates to match block copolymer assembly rates. The rapid assembly enables the encapsulation of multiple drugs and imaging agents into the same nanoparticle, and the production of multivalent targeted nanoparticles. The flexibility of the assembly process enables the preparation of imaging nanoparticles based on various modalities:
1. Fluorescent imaging of new hydrophobic long wavelength dyes that have exceptional photostability and are non-quenching, which enables high fluorophore loading. They reside in the core of the nanoparticle and are therefore unaffected by the biological environment, and do not contribute to surface recognition artifacts that may affect most surface-functionalized fluorphors.
2. MRI imaging where the co-encapsulation of SPIO magnetic nanoparticles and therapeutic agents enables into the same nanocarrier enables MRI contrast equivalent to commercial MRI agents, which can not simultaneously delivery therapeutics.
3. Up Converting Phosphors (UCPs) that enable both deep optical penetration of tissue and co-delivery of agents for photodynamic therapy.
The uniqueness of the process is that this wide range of therapeutic and imaging nanoparticles can be prepared using the same platform, and that the process is scaleable from the laboratory to large-scale production.
An experiment set up in 1944 at Trinity College Dublin to demonstrate the viscosity of pitch has yielded a drop captured on video.
This is a lesser known version of the older experiment established in 1927 at The University of Queensland.
The ASR has one complimentary pass to the Slurry Pipelines Summit, which will be awarded to a WA-based ASR member.
The winner must have their primary work or residential address in WA.
The winner must be an ASR member (full or postgraduate) with financials up-to-date as of August 22nd.
The candidate's entry must consist of up to 250 words explaining why the candidate would benefit from attending the summit.
The winner commits to attend the summit and write an article about the summit for the bulletin.
The winner may be asked to give a short presentation about ASR (notes will be provided).
The winner is determined at the judges' sole discretion.
With 2013 being the thirtieth anniversary of the Australian Society of Rheology, the Annual General Meeting was suitably graced with two special guest presentations, and the award of an ASR Medallion, in the presence of two previous Medallion recipients.
The proceedings commenced with the formal business, with addresses by the President and Treasurer. The Secretary co-ordinated the voting in of the new Council, which comprised all of the previous Council, plus the addition of Jason Stokes.
We next heard an explanation of the heritage of the ASR Medallion from esteemed sculptor Michael Meszaros.
Having set the scene, ASR President Mark Coghill presented an ASR Medallion to Prof. Sati Bhattacharya (RMIT), for his lifelong achievements in the field of rheology.
In attendance were two of the three previous recipients, Prof. Roger Tanner and Prof. David Boger.
Prof. Boger later gave an after-dinner speech, emphasising inter alia the importance of rheology in handling tailings, and allowing dry stacking rather than creation of dams of wet slurry that are prone to collapse.
