The effect of the laminar velocity profile and its variation on mixing phenomena at the reduced scale is studied. It is shown that the diffusive mass flux between two miscible streams, flowing laminar in a microchannel, is enhanced if the velocity at their diffusion interface is increased. Based on this idea, an in-plane passive micromixing concept is proposed and implemented in a working device (sigma micromixer). This mixer shows considerable mixing performance by periodically varying the flow...

Binary betting is a relatively new concept to both traders and investors, and has really only been available for the financial markets in the last 2-3 years. It is gaining in popularity for reasons which I hope will become clear shortly. For those of you familiar with fixed odds betting, and also spread betting, binary betting provides a bridge between the two worlds.

Solid-liquid equilibria in the system propanoic acid-formamide were determined from time-temperature cooling and warming curves. In the system, two solid adducts, stable and metastable, were found and their equilibrium dissociation constants were calculated. \copyright 2007 Institute of Organic Chemistry and Biochemistry.
