China has made significant progress in magnetic confinement fusion over the past decade. With the successful operation of its nuclear fusion machine, the Experimental Advanced Superconducting Tokamak (EAST) since 2006 and headway in the International Thermonuclear Experimental Reactor (ITER) project, the country is achieving significant gains toward advanced steady-state operations and next steps in nuclear energy production.

Chemists describe a new form of ice
Scientists from the United States, China, and Russia have described the structure and properties of a novel hydrogen clathrate hydrate that forms at room temperature and relatively low pressure. Hydrogen hydrates are a potential solution for hydrogen storage and transportation, the most environmentally friendly fuel. The research was published in the journal Physical Review Letters.
Ice is a highly complex substance with multiple polymorphic modifications that keep growing in number as scientists make discoveries. The physical properties of ice vary greatly, too: for example, hydrogen bonds become symmetric at high pressures, making it impossible to distinguish a single water molecule, whereas low pressures cause proton disorder, placing water molecules in many possible spatial orientations within the crystal structure. The ice around us, including snowflakes, is always proton-disordered. Ice can incorporate xenon, chlorine, carbon dioxide, or me
