Air-permeable hydrogels through viscoelastic phase separation of aerogels

Nature, Published online: 08 July 2026; doi:10.1038/s41586-026-10712-3

Viscoelastic phase separation is used to fabricate non-collapsible, air-rich networks in high-water-content hydrogels containing silica aerogel beads, allowing air to permeate through the material and enabling a tenfold increase in oxygen permeability over pristine hydrogels.

Lattice reconstruction strategy for fast-charging plateau-type hard carbon anodes in ultra-long-life sodium-ion batteries

By decoupling defect passivation and graphitization, lattice reconstruction of hard carbon yields large interlayer spacing, small crystallites, and an inorganic-rich SEI, enabling superior fast-charging in ultra-long-life sodium-ion batteries.
