SME enhances Nanocube Memory Ink production

Australian innovator Strategic Elements has secured a second round of production for Nanocube Memory Ink after producing the largest batch of its kind for industrial use.

Operating under the federal government’s Pooled Development Fund (PDF), the company is working with nanomaterial scientists for the manufacturing division at the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

After confirming the production of a large-scale batch – 400 times the volume of previous batches ­– CSIRO has agreed to continue development on the project.

Nanocube Memory Ink was invented at the University of New South Wales (UNSW) by a team led by Professor Sean Li from the school of Materials Science and Engineering.

The versatile ink contains billions of nanoscale cerium oxide cubes that can be printed or coated onto both silicon and non-silicon surfaces such as glass or plastic.

The commercial goal is to bring memory and sensing to devices and surfaces with different shapes and new flexible forms that are not currently possible with rigid silicon-based technologies.

Previously, the volume of ink produced in batches at UNSW was made for prototype production. Subsequently, Strategic Elements approached CSIRO to develop a methodof creating batches of the nanocube ink on a much larger scale.

Due to recent results, a new program with the VTT Technical Research Centre, in Finland, will analyse and optimise memory ink film thickness and device operation and performance.

In addition, the VTT team will test standard industry electrode architecture and configurations, while Li at UNSW has recently acquired advanced printing and slot die coating equipment.

“We are very pleased with the outcome of the first stage of work with CSIRO,” said Strategic Elements managing director Charles Murphy.

“The company is very fortunate to be working with world-class organisations such as CSIRO, VTT and UNSW and we will continue to build on these results in the next stage of work.”
