According to an SEC filing, SpaceX (SPCX.O) has begun offering senior unsecured notes and will use net proceeds to repay outstanding borrowings.

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 rate of 38.1 kg/hr per m2, 8.5x the team’s prior 2D films. In a 30-day accelerated seawater aging test there was no nanoparticle shedding; the material produced no photo-induced reactive free radicals and addressed organic-substrate degradation. Results published in Advanced Materials. The team is working to improve condensation efficiency and reduce system costs to enable scale-up for coastal water-scarce regions, islands and remote agricultural irrigation.

U.S. Vice President Vance said he hopes Lebanon's sovereignty will be respected.
