And the winner is…
The votes are in, the ANFF-VIC Image of the Year Competition has been won by Dr Tridib Saha for his submission, “Rebel”, following a public vote on our twitter page.
Tridib’s work on improving the efficiency of ultraviolet (UV) sensors produced the image, demonstrating that nanofabrication is not only important, but also easy on the eye.
Tridib’s research required the creation of zinc oxide nanostructures on a piezoelectric crystal, langasite. The result is a ZnO-based thickness shear mode resonator that has demonstrated exciting benefits over predecessor technologies. The device, once refined, could potentially be used to generate low-power UV sensors, and therefore as energy-efficient alternatives for a feast of remote sensing applications.
Tridib’s work was conducted at Monash University Malaysia and characterised in part at the Melbourne Centre for Nanofabrication (MCN). MCN’s laser Doppler vibrometry equipment was used to take non-contact measurements of the surface of Tridib’s ZnO sensor.
ANFF-VIC would like to thank all of this year’s competitors and all of those who voted. The full submissions list is linked below and make sure you enter next year’s competition.

Title: "Astronaut"
Description: "The ‘Astronaut’ shown here is a silica hollow capsule, which is prepared by one step wet chemistry method at room temperature. The nano-scale cute ‘astronaut’ silica capsule is a promising material with potential applications as nanoreactor, template and for sustained release."

Description: Images of a gold substrate used for training of FIB users at MCN. The the "dots/burn marks" were created when the shutter for the ion source did not close properly after using it for imaging. As a result it started to locally degrade the substrate.

Title: “Starry universe”
Description: “One of three from a failed experiment. They were taken purely because I liked them in the artistic way (not the scientific and engineering perspectives). Resist on Si wafer after stamp-substrate separation. Colours are due to thickness variation of the resist on Si. Shapes are the results from the contributions including resist flow, air bubbles and peeling off of resist during stamp-substrate separation."
