Delta Gold Technologies (AQSE:AQT), a quantum materials company developing gold-based intellectual property, said sponsored research at Pennsylvania State University and the University of Toronto has produced technical results supporting its patent portfolio.
The Penn State team, led by chemistry department head Professor Kenneth Knappenberger, recorded a roughly 40% spin-polarised emission in gold nanoclusters, which the researchers describe as the highest figure known in any condensed-phase quantum material system.
"The approximately 40% spin-polarised emission we have recorded has not been achieved in any other material system I am aware of," Knappenberger said.
The clusters, with a radius of about 9 angstroms, are roughly an order of magnitude smaller than leading microelectronics materials, and the team has already demonstrated gram-quantity synthesis under standard laboratory conditions.
Three patent applications filed by Penn State will transfer into Delta's IP portfolio under its sponsored research agreement, and the company has agreed to expand that program to $6 million over up to six years, extending scope into quantum sensing and communication.
At the University of Toronto, principal investigator Professor Harry Ruda is working with gold in planar structures using molecular beam epitaxy, with a provisional patent filed on 5 May and specific applications planned for 2027.
Chief executive R. Michael Jones said work at both universities is "moving faster than we had expected", with the two principal investigators due to meet in London in the coming days.
