An international team of scientists, which included researchers from Nanjing Tech University, used a simple but powerful technique called luminescence spectroscopy to measure the velocities of tiny ...

A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy (in so-called Brownian motion), physicist Mark ...

Brownian motion of particles affects many branches of science. We report on the Brownian motion of micrometer-sized beads of glass held in air by an optical tweezer, over a wide range of pressures, ...

Abstract: Plane-wave and divergent-wave ultrasound imaging can speed up Doppler measurements compared to methods that use a sharp transmit beam. However, conventional pulsed Doppler and color Doppler ...

A new approach referred to as (P-w) method, has been developed at Wayne State University to determine the instantaneous friction and its components in internal combustion engines. The method is based ...
