Example Sentences

The mechanism of these pattern formations is related to the reaction-diffusion theory proposed by Alan Turing, a famous English mathematician regarded as one of the fathers of modern computing, in which the activator with a smaller diffusion coefficient induces local preferential growth.

From Science Daily

The diffusion coefficient is less than one-quadrillionth of a meter-squared per second, a billion times less than what we consider tight in most rocks we use in construction and toxic chemical waste disposal.

From Forbes

By using a transmission line model, electrical cell parameters, such as the resistances for electron diffusion and recombination, the chemical capacitance of the films, the diffusion coefficient of the redox mediator in the electrolyte, the resistance for electron transfer at the counter electrode and the series resistance of the cells can be extracted.
