Mechanical engineers at Duke University have demonstrated a tiny whirlpool that can concentrate nanoparticles using nothing but sound. The innovation could gather proteins and other biological structu...
With more than 800,000 miles of sewer pipes in the United States, wastewater utilities tasked with keeping those pipes clear have their work cut out for them.Now, a small business has developed a quic...
Researchers from MIT, Pennsylvania State University, and Carnegie Mellon University have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their ...
In this article, we use an ecient analytical method called homotopy analysis method (HAM) to derive an approximate solution of nonlinear ion sound waves equation. Actually, we solved Korteweg-de Vrie...
Short wavelength ion sound waves (2-4kHz) are detected in association with the Langmuir waves (~15-30kHz) in the source regions of several local type III radio bursts. They are most probably not due t...
May 29, 2007,Sound waves escaping the suns interior create fountains of hot gas that shape and power a thin region of the suns atmosphere which appears as a ruby red "ring of fire" around the moon d...
