Advective skew dispersion is a natural Markov process defined by a diffusion with drift across an interface of jump discontinuity in a piecewise constant diffusion coefficient. In the absence of drift ...

In the present paper the phenomenon of diffusion is examined in the light of the theory of the Brownian motion. The coefficients of self-diffusion, ordinary diffusion and thermal diffusion are ...

Diffusion is critical to processes such as drug delivery, water purification, and the normal operation of living cells. Key to the diffusion process is the manner in which the motion of one ...

This movement came to be known as Brownian motion and it allows substances to disperse and mix. Albert Einstein, in his seminal 1905 paper, explained diffusion at the microscopic level and showed that ...

This random movement is called Brownian motion, and a well-constructed motor at the nanoscale actually makes use of this to generate a directed movement (and therefore work).

At its heart, Brownian motion is still described by classical Newtonian physics, even if we cannot define a classical velocity and can only measure mean square displacement.

The system seems to be energy harvesting from Brownian motion. The amount of graphene and processing needed to achieve this energy harvesting is system is something that can make sense for certain ...

They will need millions of miniaturized circuits powering a capacitor to replace the battery for a tiny low power chip. Harvesting energy from graphene is controversial because it disproves physicist ...
