227. Diamond Surfaces for Quantum Applications

Dr Alastair Stacey (School of Physics, The University of Melbourne)

Surfaces

Oral

Diamonds exhibit remarkable properties at the confluence of biological and quantum sciences. The crystalline carbon lattice of this material acts as both a quantum vacuum, allowing long lived coherent states at room temperature, while also presenting a bio-friendly interface. Point defects in this material are now being used for an ever expanding array of quantum information and sensing...

202. Controlling the Edge-on vs. Face-on Stacking of Semicodundcting Polymers Using Diffusive Noncovalent Interactions

Oral

In thin films of semiconductor polymers, the polymer chains often exhibit distinct orientation with respect to the substrate. The planar π-face of the backbone typically orients either in an edge-on or face-on manner. Generally, an edge-on alignment is thought to be favourable for transport in thin film transistors, whereas face-on alignment is considered to improve vertical transport as...

231. The Evolution of Surface Silica Nanoparticles on Coated Steel Surfaces under High UV and High Humidity Environments Observed Using Synchrotron Macro ATR-FTIR Microspectroscopy

Dr Jitraporn (Pimm) Vongsvivut (Infrared Microspectroscopy (IRM) Beamline, Australian Synchrotron, 800 Blackburn Road, Clayton, Victoria 3168, Australia)

Corrosion of metallic surfaces is prevalent and of great concern in a wide range of industries, particularly those in transport, aviation, building and food sectors, reportedly responsible for a direct cost of $276 billion per annum(1). Galvanization has been widely used as a corrosion preventative method by coating the metallic surfaces with zinc that serves as a physical barrier to prevent...

254. The new RAIRS system at the THz/Far-IR Beamline - Laboratory Astrochemistry.

Dr Courtney Ennis (La Trobe University)

Surfaces

Oral

The second half of 2016 has seen the completion of a bespoke experiment installed at the THz/Far-IR Beamline. Funded by the ARC through CI Ennis' DECRA project, the apparatus has been designed for dual-purpose Matrix-Isolation and Reflection-Absorption Infrared Spectroscopy studies. A chamber sitting within the beamline’s Bruker FTIR sample compartment reaches high-vacuum by differential...

240. Investigation of fungal infestation on metallic and polymer surfaces using synchrotron-based macro ATR-FTIR microspectroscopy

Dr Vi Khanh Truong (School of Science, Faculty of Science, Engineering and Technology, Swinburne University of Technology)

Surfaces

Oral

Fungi possess the ability to colonize a wide array of surfaces, including metallic surfaces; the product of colonization is the proliferation and formation of a fungal biofilm followed by the degradation and alteration of the metallic surface. In particular, microbially-induced corrosion on the surface of metals occurs due to changes in the local acidity, creating galvanic and differential...

293. Photo-Switchable Block Copolymer Self Assembly

Mr Lewis Chambers (University of Queensland)

24/11/2016, 15:00

Surfaces

Oral

Block copolymers can self-assemble into well-defined, nanoscale morphologies, which are typically isotropic and lack long range order. Chemical or physical templates generated through optical lithography can direct self assembly to create morphologies with enhanced long range order and fashion them into hierarchical patterns. This ability allows the patterns formed to be optimized to be more...
