Today's Tech News: Notable or Not?

https://www.eurekalert.org/news-releases/1149674 Summary: By tailoring interfacial charge density and pore wall interactions, the engineered membrane drives specific solute molecules through at rates orders of magnitude faster than conventional porous media without sacrificing selectivity. This advanced separation technology gives chemical processors, resource recovery facilities, and industrial water purification plants a low-energy fabrication framework to replace energy-intensive thermal distillation columns.

https://www.eurekalert.org/news-releases/1148842 Summary: Decoupling water aeration interfaces using passive self-aerating porous membranes reduces electrical energy consumption in biological wastewater purification by ninety-five percent. The specialized structural layout drives oxygen transfer via natural concentration gradients, eliminating high-power mechanical air compressors and blowers. This passive oxygenation strategy offers energy-efficient infrastructure for municipal and industrial water treatment plants.
