Algas modificadas removem microplásticos da água

Pesquisadores da Universidade do Missouri desenvolveram uma linhagem modificada de algas que captura microplásticos de água contaminada ao produzir um óleo com aroma de laranja. O processo também limpa águas residuais e pode apoiar a produção de bioplásticos.

Susie Dai, professora da Faculdade de Engenharia, liderou a criação das algas por meio de engenharia genética. As algas produzem limoneno, que altera sua superfície para atrair microplásticos hidrofóbicos e formar aglomerados que afundam, sendo mais fáceis de coletar.

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 the University of Michigan have discovered that common nitrile and latex lab gloves release particles resembling microplastics, potentially inflating pollution estimates. The study, led by Madeline Clough and Anne McNeil, traced contamination to stearates in the gloves during sample preparation. Switching to cleanroom gloves could reduce false positives significantly.

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.

Researchers from India and Singapore report a crystalline membrane made from polyoxometalate clusters whose intrinsic openings are about 1 nanometer wide, enabling unusually sharp molecular separations that could help lower energy use in some industrial purification and water-reuse steps.
