A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...

When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline ...
