Chromium Electroplating Solutions as Two-Phase Fluids: The Influence on Solution Conductivity

The contribution of N.T. Kudryavtsev (and later his son V.N. Kudryavtsev) to the development of electrodeposition science and technology, and especially to that of chromium, is inestimable. It is a privilege on this occasion to present some considerations of the two-phase nature of chromium electroplating solutions, caused by the generation of hydrogen gas and the use of vigorous air agitation, and to discuss its influence on fluid conductivity and consequent power consumption during electrodeposition.     

On <Emphasis Type="Italic">g</Emphasis>-functions for Laguerre function expansions of Hermite type

We examine weighted L ^p boundedness of g-functions based on semigroups related to multi-dimensional Laguerre function expansions of Hermite type. A technique of vector-valued Calderón–Zygmund operators is used.
