video: This is a demonstration of the local optical heating (speed is 29x real time). The crystal melts fast at such strong heating, and re-crystallizes after the light is turned off. This video relates to a paper that appeared in the Oct. 5, 2012, issue of Science, published by AAAS. The paper, by Ziren Wang at Hong Kong University of Science and Technology in Hong Kong, China, and colleagues was titled, "Imaging the Homogeneous Nucleation During the Melting of Superheated Colloidal Crystals." view more
