In this work, a synergistic MXene/(NH₄)₂SO₄ treatment strategy is proposed and systematically validated. By combining salt‐out processing based on the Hofmeister effect with a MXene-enabled conductive network, a double‐network MXene-composite hydrogel is fabricated. At an extremely low filler content (0.12 wt%), MNMSPC hydrogel exhibits an approximately threefold improvement in overall mechanical performance, including strength, toughness, and stretchability. Meanwhile, the gel achieves efficient broadband EMI shielding covering the X, Ku, Ka, and terahertz frequency bands, with a maximum shielding effectiveness exceeding 60 dB, together with excellent infrared stealth performance.

A thousand times faster than conventional testing, an ion beam approach to qualifying materials for use in the cores of advanced nuclear reactors is advancing through stages of approval by the industry standards organization ASTM. 

The methodology, developed with leadership by University of Michigan Engineering, will be presented at a special event hosted by the Electric Power Research Institute, March 10-11 in Charlotte, North Carolina. 

Dining on the moon or Mars might seem like a fantasy reserved for science fiction, but researchers are investigating how it could become a reality. Their efforts to recycle plant and human waste into a fertilizer material — turning the barren surfaces of the moon and Mars into fertile fields that might be suitable for extraterrestrial agriculture — are described in ACS Earth and Space Chemistry.

​Scientists have warned that the world’s tiniest organisms need to be taken into account in efforts to improve soil health. AMI has launched a new policy report setting out key recommendations to support the long-term protection, restoration and sustainable management of soils across the UK’s four nations.
