Reported in Science Bulletin, a new study presents the design and fabrication of an ultra-robust and multifunctional ionic biogel with multiscale architecture via a synergistic structural engineering strategy, and demonstrates its application in self-powered human interaction.

Researchers have developed a green separation process combining a tailor-made ionic liquid with heat pump technology that slashes energy consumption by 48.68% for separating dimethyl carbonate from methanol—a critical bottleneck in sustainable chemical production. Using a multi-scale strategy spanning molecular screening, experimental validation, and process optimization, the team identified an eco-friendly ionic liquid entrainer that breaks the stubborn azeotrope between these industrially important chemicals, paving the way for more sustainable and cost-effective manufacturing.

Researchers have developed a quantum-dot imaging technique that makes the usually difficult to visualize surface plasmon polaritons visible with a conventional fluorescence microscope. The method captures and measures plasmonic waves in device structures intended for practical use, including buried interfaces, providing a practical tool for designing future nanophotonic, optoelectronic, and plasmonic technologies.

Salk scientists identify two cellular programs linked to age-related dysfunction, ferroptosis and senescence, are mechanistically linked through the enzyme acid ceramidase. The team finds that senescent “zombie” cells are more vulnerable to regulated cell death through ferroptosis and that they can pass that sensitivity on to neighboring cells. The observations suggest acid ceramidase could be a powerful therapeutic target for supporting healthy aging and preventing age-related diseases and disorders such as arthritis, dementia, and cancer.
