"scalable... starting materials with milling balls shaken at high frequencies thoroughly mix... photoreactor adapted to mill under irradiation facilitated photo-mechanochemical synthesis of solid state nanographenes... reduced reaction times by up to 56%, while using 98% less solvent than in equivalent syntheses done with conventional methods. Last but not least, the new photoreactor consumes almost 80% less energy than conventional equipment?
