University develops solar desalination without toxic brine

May 31, 2026

由 AI 报道

Researchers at the University of Rochester have created a solar-powered system that converts seawater into fresh water while avoiding the production of harmful liquid brine. The technology uses laser-textured panels to evaporate water and collect salts as solids.

The system employs black metal panels treated with femtosecond lasers to absorb sunlight and wick seawater across an active surface. As water evaporates, salts are directed to passive regions using the coffee ring effect, preventing clogs during operation. Tests with samples from the Pacific, Atlantic, and Indian Oceans confirmed continuous fresh water extraction and self-cleaning performance.

Researchers at Flinders University say they have developed an adsorbent material that removed more than 98% of short- and long-chain PFAS—including hard-to-capture short-chain variants—in laboratory flow-through tests using model tap water. The approach embeds nano-sized molecular cages into mesoporous silica and, in the experiments reported, could be regenerated while remaining effective over at least five reuse cycles.

Columbia engineers create faster method to extract lithium

Researchers at Columbia Engineering have developed a new technique to pull lithium from underground brines more quickly and with less environmental harm. The approach uses a temperature-sensitive solvent and avoids the large evaporation ponds common in current production.

Scientists develop sunlight method to convert plastic waste into hydrogen

May 04, 2026 由 AI 报道

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
