Scientists use nontoxic silicon nanocrystals to convert low-energy photons into high-energy ones, which could lead to minimally invasive photodynamic treatments for cancer. It could also lead to new tech for solar-energy conversion, quantum information, and near-infrared driven photocatalysis.

Combining the HPQ PUREVAP™ Quartz Reduction Reactor ("QRR") technology with PyroGenesis Plasma Atomization knowhow to manufacture Nanoscale Structure Silicon (Si) powders, could potentially resolve these 2 issues and lead the way to full commercialization of Nanoscale Structure Silicon Powders
