摘要：
We have investigated new nano materials for their applicability as ice/snow melting agents. They are based on nano-textured anti-reflective (hence black) Si and compared with standard agents used in the industry. Nano needles of black-Si decrease surface reflectance and enhance absorption of sunlight by Si. The effective ice/snow melting properties of the black-Si based samples outperform the most widely used chaff charcoal. This newest solar photo-thermal conversion material/agent has high potential to the farming in early springs at relative cold regions.
