The material at the heart of this technology is a blend of wood, lithium chloride, and a solar-absorbing surface made of carbon nanotubes. These ingredients form a strong, porous sponge that can ...

(Nanowerk Spotlight) One-third of the global population lacks access to clean water, with the challenge most severe in arid regions that make up 41% of Earth's land surface. The atmosphere holds vast ...

Engineers from Australia and China have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other ...
