1. Reconfigurable image processing metasurface

   In work just published in Nature Communications, a collaboration between University of Melbourne, CUNY, and RMIT University has demonstrated a metasurface that can be switched between edge detection and producing a conventional image. The device integrates a thin film of VO2 that undergoes a phase change at around 68C altering its optical properties opening up […]

2. New ultra-thin ammonia sensor

   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 […]
