"Nano-sized snow crystals could be an interesting candidate for boosting the coupling efficiency of high intensity laser energy into matter." "The researchers discovered that the large flakes behaved as solid targets in their own right and failed to enhance the absorption of incident laser radiation. In contrast, the team believe that the smaller clusters were highly ionized, which helped to increase the laser absorption from 58% for a bare sapphire surface to 97% when the target was covered with snow." "Our interest is purely academic, but one application of the technique is the generation of an efficient neutron source," explained Zigler. "The next step will be to generate fine structured snow flakes from heavy water." Nano "snow flakes", think about it. Smart Dust technology. nanotechweb.org/cws/article/tech/27032
