Growth of convection and boundary layers in binary mixtures

In binary mixtures exposed to gravitation and a large enough temperature gr adient a complicated transition occurs from a pure heat-conducting to a con vective state. During this transition, the spatiotemporal behaviour of the concentration field in the bulk of the layer and close to the boundaries va ries dramatically, which is the main issue of this publication.
