Nanotechnology is speaking!: new materials to cause rain

Needing rain desperately in my town and other parts of the world, I'd like to share an interesting study from London Centre for Nanotechnology and University College London. The article to introduce the study is titled "Molecular ice chain structure could be used to seed clouds and cause rain" and freshly uploaded on the Nanowerk site, waiting to be read:-)

The article reports that "This week's Nature Materials (9 March 2009) reveals how an international team of scientists led by researchers at the London Centre for Nanotechnology (LCN) at UCL have discovered a novel one dimensional ice chain structure built from pentagons that may prove to be a step toward the development of new materials which can be used to seed clouds and cause rain."

Dr Michaelides says: "For the first time, we have shown that ice can build an extended one dimensional chain structure entirely from pentagons and not hexagons. This discovery leads to fundamental new understanding about the nature of hydrogen bonding at interfaces (there is no a priori rule that hexagons should form) and suggests that when people are searching for new ice nucleating agents which can be used to seed clouds and cause rain, they do not necessarily need to focus on materials that have hexagonal surfaces - other types of surfaces may be good too."

Look forward to more progressing studies in this area! Your thoughts?
