Tailoring the nanostructure of a supercapacitor with desired functionality necessitates both architectural and structural designs. Ultrathin two-dimensional architecture has emerged as one of the most promising candidates owing to the advantage of short diffusion pathways. Moreover, structural modifications through creation of exposed defects at the electrolyte intersection would maximise...

50. In-situ X-ray powder diffraction for Li-ion batteries: The effects of Ni on inhibiting the separation of Cu during the lithiation and delithiation of Cu6Sn5 anodes

Oral

Lithium-ion batteries have found numerous applications in modern technologies, especially in portable devices, and increasingly in electric vehicles and renewable energy storage applications. Sn-based lithium-ion battery anodes have a higher theoretical storage capacity of 993 mAh g^-1 vs. 372 mAh g^-1 compared to commercial carbon-based anodes. Their better safety profile...

7. The Electronic and Vibrational Structure Of Lanthanide Zirconates

Advanced materials

Oral

The lanthanide zirconates are of interest for their use in inert matrix fuels and as nuclear wasteform containment material. For use in these applications, the material's structure must be as resistant as possible to radiation damage, and, therefore, at a basic level, present an electronic and vibrational structure with thermodynamic and mechanical properties that are favourable to long term...

83. Radiation Damage Characterisation of Organic Semiconductors

Oral

The radiation damage of a fullerene-composite bulk heterojunction organic photodetector was characterised for samples that have been exposed to ionising radiation in increments of 10kGy up to a total accumulated irradiation dose of 40kGy. Irradiation was achieved by a cobalt-60 gamma source (dose rate = 1.2kGy/h) at the Australian Nuclear Science and Technology Organisation. Between each...

100. Investigation of the stability range of the skyrmion phase in doped Cu$_2$OSeO$_3$

Clemens Ulrich (The University of New South Wales)

Advanced materials

Oral

A skyrmion is a topological stable particle-like object comparable to spin vortex at the nanometre scale. It consists of an about 50 nm large spin rotation which order in a 2 dimensional, typically hexagonal superstructure perpendicular to an applied external magnetic field. Its dynamics has links to flux line vortices as in high temperature superconductors. Cu$_2$OSeO$_3$ is a unique case of...

128. Shedding light on the subtle differences in Li-S cell operation when using safer ionic liquid based electrolytes

Lisa Djuandhi (UNSW)

Advanced materials

Oral

Lithium-sulfur (Li-S) batteries have the potential to replace lithium-ion batteries due to their high theoretical energy density and potentially reduced environmental impact. However, they still face many challenges in terms of operation and safety to become more attractive in a commercial-standpoint. Of particular interest is the use of safer, less-flammable electrolyte compositions involving...
