Universidade desenvolve dessalinização solar sem salmoura tóxica

Pesquisadores da Universidade de Rochester criaram um sistema movido a energia solar que converte água do mar em água doce, evitando a produção de salmoura líquida prejudicial. A tecnologia utiliza painéis com texturização a laser para evaporar a água e coletar os sais como sólidos.

O sistema emprega painéis metálicos pretos tratados com lasers de femtossegundo para absorver a luz solar e conduzir a água do mar por uma superfície ativa. À medida que a água evapora, os sais são direcionados para regiões passivas usando o efeito de anel de café, evitando obstruções durante a operação. Testes com amostras dos oceanos Pacífico, Atlântico e Índico confirmaram a extração contínua de água doce e o desempenho de autolimpeza.

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.

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.

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.

Two companies have tested pumping seawater onto Arctic ice to increase its thickness and slow summer melting. Field trials in Canada and Norway produced thicker ice but showed varying effects on how long it lasted.
