The Journal of the Acoustical Society of America, 1964 Tapered solid elastic rods have previously been used as horns or velocity transformers for longitudinal and torsional vibrations. Such structures may also be employed as velocity transformers when vibrating in flexure. An approximate 1-dimensional wave equation describing the vibration of such “flexural horns” has been derived from thin-bar theory. The

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion
Advanced Materials Technologies, EarlyView.This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off
