Celani, ICCF18 paper:
"In addition to Ahern, Thomas Prevenslik also recently noted the
extraordinary thermodynamic properties of nanometer-sized
objects. Prevenslik supports the possibility of nanoscopic particles
to behave as frequency multipliers able to generate high-energy
photons from a much larger number of photons of lower energy."
nanodiamonds may act as an effective "Prevenslik catalyzer"
