Last week in Canberra, PhD student Shaban Sulejman was announced as a 2024 Fulbright Future Scholar and recognized by the US ambassador to Australia Caroline Kennedy. Shaban will be taking up the scholarship later in the year to work with TMOS Partner Investigator Professor Andrea Alu at CUNY.
In work led by McKenzie Fellow, Dr Nitu Syed, researchers from the ARC Centre of Excellence for Transformative Meta-Optical Systems, have developed a gas sensor using atomically thin transparent two-dimensional (2D) tin dioxide film. The material has a thickness of only 2 nanometres which is 50000 times thinner than a paper. Reducing the thickness to only a few atoms substantially increase the flexibility of the material and makes it ideal for integration into wearable devices such as smartwatches and medical patches. An article about describing this work is here and the originally (open access) article can be accessed by following this link.
Work led by Tim Davis is featured as an Editor's Pick in the latest Optics Express - link here. We show that by extracting structural information from transmission electron microscopy data, including characteristic disorder parameters, good agreement with spectral specular and non-specular reflectance measurements can be obtained.
The Australian Research Council Centre of Excellence for Transformative Meta-optical Systems (TMOS) is currently seeking expressions of interest from prospective PhD research higher degree and MSc coursework students. Students should send an expression of interest to Professor Ken Crozier and/or Professor Ann Roberts - a list of potential projects can be found here. Applications need to be submitted before the 14 October to be considered in the first round for 2024 so prospective supervisors need to be contacted well before then. Note that entry to the PhD program at the University is highly competitive and only very high achieving students will be encouraged to submit a full application. Information about PhD studies at Melbourne, including eligibility and the application process can be found here and MSc coursework in Physics here.
In work just published in Materials Today Advances, members of the group, led by Laura Ospina-Rozo, report new results into the optical and near-infrared properties of beetle elytra. We showed that some scarab beetles use composite, non-chiral structures to reflect light where the elytra consist of a broadband reflective structure overlain by a green filter. The green near-infrared reflective elytra may enable both camouflage and passive cooling.
Members of the Melbourne node, Dr Wendy Lee, Dr Lukas Wesemann and PhD student Shaban Sulejman attended the official launch of the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at ANU on the 28th September. The launch was attended by Australian Research Council Chief Executive Officer Ms Judith Zielke, ANU Vice Chancellor Prof. Brian Schmidt in attendance and ANU Chancellor Julie Bishop in attendance.
Work led by Lukas Wesemann published in ACS Photonics reports the use of a metasurface for generating pseudo-3D images of phase objects. His subsequent article in The Conversation discusses its potential application to disease detection.
A new paper led by PhD student Niken Priscilla reveals an intriguing device which exhibits a different colour variation when observed from either side. Unlike previous research the structure involves four simple nanoscale thickness layers of silica, silver and chromium. The research has been published in Advanced Photonics Research - link here.
Dr Alexander Wood is the recipient of the 2021 Woodward Medal in Science and Technology for his suite of publications in Nature Physics, Science Advances and Physical Review Letters concerning how physical rotation can be used as a tool for control and measurement of a quantum system. The Woodward Medal was established to reward outstanding and original scholarship. Congratulations, Alex!
Faris Shahidan has led new work appearing today in Optics Express. Using nanoimprint lithography we show that it is possible to generate vivid colouration without the requirement for polarised light. Embossed polymers are coated with a variety of metals permitting an investigation of the role of the choice of metal. This work opens up the prospects for applications in manufacturing and elsewhere.
