Ultrathin films of widely different materials exhibit a dramatic enhancement of projectile penetration resistance under high–velocity impact. Despite extensive simulations and experiments, a unifying ...

In iron-based superconductors, the dz2 orbital band lies deep below the Fermi energy and is conventionally excluded from the superconducting pairing process. This work overturns this view. Using a ...

Multilayer graphene moiré systems have revealed rich correlated and topological quantum phases, yet twisted transition metal dichalcogenides have been studied mainly as bilayer. Here we show that ...

Habitat split drives assembly of less protective host microbiomes ...

Lü raises an important broader question about aerophilic interfaces: how nanobubbles form, persist, and influence surface behavior over longer timescales. We believe that this is an interesting ...
