Sound waves create whirlpools to round up tiny signs of disease
Sound waves create whirlpools tiny signs of disease
2017/2/16
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...
Enhanced sequential carrier capture into individual quantum dots and quantum posts controlled by surface acoustic waves
Quantum Dots Quantum Posts Surface Acoustic Waves
2010/11/24
Individual self-assembled Quantum Dots and Quantum Posts are studied under the in uence of
a surface acoustic wave. In optical experiments we observe an acoustically induced switching of the occupanc...
Five-minutes oscillations is one of the basic properties of solar convection. Observations show mixture of a large number of acoustic wave fronts propagating from their sources. We investigate the pr...
Dynamic radiation force of acoustic waves on absorbing spheres
Acoustic Radiation Force Viscoelasticity Scattering
2010/6/30
We present a theoretical study on how dynamic radiation force of acoustic waves actuates on absorbing spheres. We consider the radiation force is generated by the difference-frequency component of a b...
