Why isnt it melting? The bonding of structures at the nanoscale usually involve what? POLYMERS. Polymers have a high heat tolerance. Proof? Ecology Coatings is the company in the United States that makes the ethylene-vinyl acetate nanocrystals for Fire Standard Cigarettes (FSC). This can be googled for proof. Nanotechnology in City Environments (NICE) Database By the Center for Nanotechnology in Society, Arizona State University Using Nanotechnology to Induce Rain—Cloud Seeding Cloud seeding is the induction of rain by seeding clouds with dry ice or chemicals via airplane. While this may sound like something from science fiction or a super villain story, weather control is real, and a number of countries, including the United States use cloud seeding techniques. Current techniques use dry ice or silver iodide since they both share the hexagonal microstructures inherent in snow. The theory is that clouds seeded with hexagonal microparticles will produce rain or snow as the particles act as nucleating agents. Super cooled water near the top of the cumulus cloud adheres to the microparticle, making it large enough to fall to the earth. While this conventional method of cloud seeding has been shown to definitively change the shape and behavior of clouds, its ability to induce rain is debated. Furthermore, the structure of ice is not well understood at the nanoscale. Recent research from scientists at the London center for Nanotechnology has proven that ice at the nanoscale has a crystalline structure that is pentagonal rather than hexagonal, opening the door for new, and potentially more effective chemicals for cloud seeding. In the future, nanoparticles of different, and less ecologically toxic nature than silver iodide, may be used to exploit the hydrogen **bonding properties at bond interfaces**.
