A high-efficiency circular vibration/polarization ultrasonic conversion technology capable of detecting cracks, which can occur in various directions within a structure, has been developed for the ...

Recent advances in the study of acoustic radiation and vibrational analysis of circular plates have significantly deepened our understanding of how structural motions generate sound. This field ...

Scientists engineered a nanostring that cascades energy through five vibration modes from a single push, opening new paths for ultrasensitive nanoscale sensors.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The last few years have shown progress in finite-element analysis intended for use by design engineers. Many programs that work with CAD provide several different types of analysis, and the range of ...

(Nanowerk Spotlight) A theory analysis of energy/momentum conservation laws in a spatially confined coupled system of nearly free electrons and phonons hints that the absorption of electromagnetic ...
