Compatibility testing of spacecraft materials and spacestorable liquid propellants [PDF]
Compatibility data for aluminum alloy 2219-T87 and titanium alloy Ti-6Al-4V were obtained while these alloys were exposed to both liquid and vapor fluorine and FLOX at -320 F + or -10 F.

Advanced Materials, EarlyView.A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials
Advanced Materials, EarlyView.Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Atomically‐Thin Freestanding Racetrack Memory Devices
Advanced Materials, EarlyView.Ultrathin and flexible freestanding racetrack membranes are fabricated using a water‐soluble Sr3Al2O6 release layer, without a buffer between the release layer and the magnetic heterostructure. The absence of any buffer layer enables local modulation of the current‐ and field‐induced manipulation of the racetrack magnetization via direct coupling with ...

Surface roughness-informed fatigue life prediction of L-PBF Hastelloy X at elevated temperature [PDF]
arXivAdditive manufacturing, especially laser powder bed fusion (L-PBF), is widely used for fabricating metal parts with intricate geometries. However, parts produced via L-PBF suffer from varied surface roughness which affects the dynamic or fatigue properties.

Advanced Materials Interfaces, EarlyView.Atomic transition rates for manipulating single silicon atoms in graphene with an electron beam in the scanning transmission electron microscope are experimentally extracted. Automated experiments and deep learning methods provide a means to probe and collect vast amounts of data to determine transition probabilities as a function of beam coordinate. A
