Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Propellants, Explosives, Pyrotechnics, EarlyView.This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Safety Science and Technology, EarlyView.Explosion process of propylene oxide (PO)/Al/AlH3/air was investigated. The PO/Al/AlH3/air multiphase clouds under strong ignition detonation have reached a quasi‐detonation state. ABSTRACT Fuel‐air explosives (FAE) are an important source of explosion energy. The density advantage of aluminum hydride (AlH3) dust is obvious compared with that of liquid

Critical point drying of brain tissue for X‐ray phase‐contrast imaging
Journal of Synchrotron Radiation, EarlyView.X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.
