New Journal of Physics, 2010 The paper addresses a new approach to passive acoustic cloaking, which is an alternative to the well-known approach of transformation optics. It is shown first that the scattered acoustic field of a body is completely determined by special surface impedances defined at the body surface. The surface impedances of a non-scattering, i.e.

Double-negative flexural acoustic metamaterial
New Journal of Physics, 2014 We present an acoustic metamaterial for flexural waves with both negative density and elastic modulus. By means of an analytical lumped-element approach, we introduce a combination of resonant elements on the surface of a plate.

Advanced Science, EarlyView.We developed an ultrasound‐controlled biomimetic nanoplatform, mRNA/V@M NPs, to co‐deliver CD74 mRNA and V‐9302 for fibrotic TNBC therapy. CD74 mRNA reprograms myCAFs into antigen‐presenting apCAF cells through the CD74‐MHC II pathway, while V‐9302 induces ICD and activates MHC I‐CD8+ T cell immunity.

Machine Learning Driven Inverse Design of Broadband Acoustic Superscattering
Advanced Intelligent Discovery, EarlyView.Multilayer acoustic superscatterers are designed using machine learning to achieve broadband superscattering and strong sound insulation. By incorporating a weighted mean absolute error into the loss function, the forward and inverse neural networks accurately map structural parameters to spectral responses.
