Ice surfaces have a thin layer of water below its melting temperature of 0℃. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the phase transition (such as melting and freezing) temperature. Besides premelting and prefreezing, whether similar surface phenomenon exists as a precursor of a phase transition has rarely been explored. Read More...
The surface of a colloidal crystal develops another crystal whose thickness increases with temperature in a power law before reaching the crystal-crystal transition temperature.
A research team from the Hong Kong University of Science and Technology (HKUST) has developed the world’s most productive...
Researchers at the Hong Kong University of Science and Technology (HKUST) developed a novel technology which allows genomic DNA and RNA sequencing to be carried out simultaneously in single cells of both frozen and fresh tissues, and identified rare brain tumor cell "spies" disguised as normal cells with this method. This breakthrough facilitates cancer research for some of the most complex and rare tumors, opening new directions for drug target discovery in the future.
