Researchers at the Institute of Process Engineering, Chinese Academy of Sciences, with Shenzhen University developed a polymer "latch" mechanism to assemble nanoparticles into a three-dimensional photothermal evaporator that sharply raises solar-driven seawater evaporation. The structure achieves 90.2% solar absorption; nanoscale confinement alters the water hydrogen-bond network and cuts the energy required for the same evaporation volume by 45.7%. A single evaporator recorded an evaporation ra

U.S. Vice President Vance said he may hold discussions with nuclear inspectors today.

CSC Financial research note says Chinese dental zirconia makers have received notices from Japan's Tosoh suspending supply of zirconia powder, signaling raw-material shortages have moved from expectation to reality after overseas rare-earth constraints. YSZ (yttria-stabilized zirconia), a yttria-doped high-performance ceramic, faces steep domestic-foreign price divergence: domestic yttrium oxide quoted about 55,000 yuan/ton, Rotterdam port price $457.50/kg and Baichuan reports a European price of $1,175/kg, with some spreads exceeding 100x. Baichuan data show similar widening for other oxides: dysprosium ~8x, terbium ~5x, gadolinium ~40x, scandium ~6x. Rare earths are essential additives for high-end materials and manufacturing; tightening overseas supply and expanding spreads imply Chinese producers of rare-earth-added high-end materials could gain global market share, supporting upstream, midstream and downstream segments of the domestic rare-earth industry chain.
