Zhang, X. (author)With the aims of understanding the protective mechanism of chromate conversion coatings and developing alternatives to chromate treatments, the physical natures and corrosion properties of Cr(VI) and Cr(III) treated zinc have been investigated in this work. The Cr(VI) treatments were carried out in dichromate and sulfuric acid solution with...doctoral thesis 2005

Zhang, L.X. (author), Leburton, J.P. (author), Hanson, R. (author), Kouwenhoven, L.P. (author)We show that the design of a quantum point contact adjacent to a quantum dot can be optimized to produce maximum sensitivity to single-electron charging in the quantum dot. Our analysis is based on the self-consistent solution of coupled three-dimensional Kohn-Sham and Poisson equations for the quantum circuit. We predict a detection sensitivity...journal article 2004

Wang, X.W. (author), Gao, F.L. (author), Zhang, X.M. (author), Ruan, B.Q. (author)Water resources contribute greatly to human well being, both directly and indirectly. Water resources are irreplaceable natural resources, and are limited. However, due to a growing population and related economic development, the water demand from urban, industry and agriculture has increased dramatically. Water shortage has become one of the...report 2002

Rem, P.C. (author), Zhang, S. (author)The present invention relates to a method of separating non-ferro metal particles using a rotating magnetic field. According to the invention the particles are surrounded by a fluid restricting the fall-velocity significantly, suitably a fluid having a density of at least 0.1 kg/l. The presence of such a medium causes the particle, if it is a...patent 2000

Rem, P.C. (author), Zhang, S. (author), Forssberg, E. (author), De Jong, T.P.R. (author)Separability and separation mechanisms of small particles in modern rotating type eddycurrent separators (ECSs) were discussed in Part I. In order to address problems associated with this design concept, a number of novel ECSs, each with a unique design, have been developed. Part II reports on investigation into the separability and separation...journal article 2000

Zhang, S. (author), Rem, P.C. (author), Forssberg, E. (author)Owing to the growing emergence of the end-of-life electrical and electronic products with complex material structures and an ever-diminishing particle size of the valuable metals involved, development of eddy current separators (ECS) has been targeting selective separation of small non-ferrous metal particles smaller than 5 mm. Separability of...journal article 1999

Zhang, C.K.

Zhang, C. (author)In the last decade, several mathematical models for cross-shore sediment transport have been developed under the assumption that the instantaneous sediment transport is directly related to the instantaneous horizontal velocity just above the boundary layer. Although some models took beach slopes into account, most of the calibrated data were...report 1994
