Advanced Materials, EarlyView.Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...

The Effect of Geometrical and Material Modification of Sound Diffusers on Their Acoustic Parameters
Archives of Acoustics, 2013 Sound diffusers, in particular those based on changes in the phase of the reflected wave (Schroeder diffusers), have recently gained greatly in popularity in acoustics as an effective means to eliminate defects and improve the acoustic performance of ...

Advanced Materials, EarlyView.Er3⁺/Mn2⁺ co‐doped ZnS/CaZnOS heterostructures are developed for remote temperature and force/sound sensing. The material exhibits UV/NIR photoluminescence, with energy transfer influencing color. Mechanoluminescence intensity is measured against applied power. Temperature‐dependent photoluminescence enabled luminescence thermometry.

Advanced Materials Interfaces, EarlyView.This study investigates how the mode of application affects drug delivery from coated microneedles. Combining finite element modeling with custom 3D‐printed Franz Diffusion Cells, the researchers found that prolonged application pressure from microneedles in situ reduces drug permeation.
