An Acoustic Lens for Underwater Sound [PDF]
The Journal of the Acoustical Society of America, 1947 In order to meet a demand for plane or converging waves in underwater acoustic measurements an acoustic lens has been developed. The lens employs carbon tetrachloride contained in a metal form. The curved surfaces of the lens are spun to the desired curvature from 0.026-in. aluminum sheet, and these are assembled with a brass frame.

Advanced Science, EarlyView.Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.
