Members of the Australian Institute of Physics, Queensland Branch.
You are invited to attend the upcoming Annual General Meeting .
The AGM will be held on the 2 November from 4pm – 6pm, Room 50-S201, University of Queensland, St Lucia Campus.
I am very pleased to announce that we will have two speakers bracketing the AGM, with the QLD nominee for the Bragg Gold Medal Dr Sarah Walden presenting her research; and the John Mainstone Youth lecture Tour presenter Dr Sean Powell. More information about their presentations are provided below.
The expected timing of the proceedings will be as follows:
4.00pm – 4.50pm Dr Sarah Walden presents her research
5.00pm – 5.15pm AGM
5.15pm – 6.00pm Dr Sean Powell – “Physics is everywhere!” Presentation from the John Mainstone Youth Lecture Tour.
For catering purposes it would be appreciated if you could register your attendance by Tuesday the 30th of October to firstname.lastname@example.org . Catering will involve pizza and cold drinks.
We additionally hope to stream the presentation online using the zoom platform. Further information will be supplied regarding the online streaming soon.
Additionally, part of the business for the AGM will be to elect the branch committee for 2019.
As per the AIP by-laws, the retiring committee has made nominations for next year’s committee, and these are listed below:
Joel Alroe (Chair) (QUT),
Joanna Turner (Secretary) (USQ),
Scott Adamson (Vice-Chair) (All Hallows),
Igor Litvinyuk (Treasurer) (GU),
Simon Critchley (Qld Health),
Austin Lund (UQ),
Nunzio Motta (QUT),
Carolyn Brown (USQ),
Till Weinhold (UQ)
Jacinda Ginges (UQ)
Scott Hoffman (post-graduate student representative UQ)
Members may make further nominations, which need to be duly proposed and seconded and forwarded to the Secretary at least 24 hours before the AGM, directed to email@example.com . I look forward to seeing you on 2nd November!

Title: Nonlinear optical properties of ZnO and ZnO-Au composite nanostructures for nanoscale UV emission
Abstract: This thesis investigates the nonlinear optical properties of ZnO and ZnO-Au composite nanostructures. For applications such as photodynamic therapy, it is desirable to use nanoparticles to generate localised UV emission while illuminating them with visible or infrared light. This is possible using nonlinear optical processes such as two photon absorption. Nonlinear optical processes however, are extremely weak, so this work investigates the potential of increasing the efficiency of two photon absorption in ZnO nanoparticles by coupling them to metal nanoparticles. Using new experimental methods, the two photon absorption and resulting UV emission from the nanoparticles are measured.

Physics is everywhere! – a journey from sub-atomic particles to the large-scale structure of the universe, where physics seeks to answer the most fundamental questions about reality. As we learn more, we can do more! Physics is everywhere in our world and underpins all our technologies. This year, Sean will discuss the important problems that all of us encounter every day: how do I teleport myself to school? What do I do when I find myself inside a black hole? Why is my time-machine not working? He will also talk about the superpowers that you can gain as a physicist, such as the ability to make accurate quantitative observations and predictive and interpretive mathematical models. These powers mean that you can become very valuable and work in many industries such as fundamental physics research, economics and finance, space and aeronautics, healthcare and medicine, learning and teaching, electronics and computers, and so much more!
