Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

open access: yesAdvanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

Solvent‐Free Mechanocatalytic Reduction of Nitro Compounds with Hydrogen Gas and its Application in the Synthesis of Drugs and their Intermediates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.
