It was found that three factors affect the biotransformation rates of A9PEO the origin of the bacterial culture, temperature, and the initial concentration of A9PE0n. Biotransformation kinetics of mixed bacterial cultures from the brackish water layer was faster than those from the saline water layer. Rate constants (based on first order kinetics) for... 

The question of compatibility in polymers, therefore, is much more complicated than the corresponding problem in low molecular weight systems. In addition, the kinetics of mixing must inevitably be considered.

Models for the static spectral sensitization of coordination compounds are discussed. Among them, ion pairs with oppositely charged metal complexes, where intervalence charge-transfer interactions occur, appear to be promising exarrples. The spectra and the electron transfer kinetics,of mixed-valence ion pairs of ihe type M /fMCNjgJ4-, where M + = Fe3 Cu2 UO V02 are discussed in detail. 

James Douglas Julio Ottino at the University of Massachusetts has just completed a book on the subject that should make this material easier to teach. The title of the book is The Kinetics of Mixing Stretching, Chaos and Transport, and it s published by Cambridge University Press.

Ni Sorption on Clay Minerals A Case Study. Initial research with Co/clay mineral systems demonstrated the formation of nucleation products using XAFS spectroscopy, but the stmcture was not strictly identified and was referred to as a Co hydroxide-like stmcture (11,12). Thus, the exact mechanism for surface precipitate formation remained unknown. Recent research in our laboratory and elsewhere suggests that during sorption of Ni and Co metal ions, dissolution of the clay mineral or aluminum oxide surface can lead to precipitation of mixed Ni/Al and Co/Al hydroxide phases at the mineral/water interface (14,16,17,67,71). This process could act as a significant sink for metals in soils. The following discussion focuses on some of the recent research of our group on the formation kinetics of mixed cation hydroxide phases, using a combination of macroscopic and molecular approaches (14-17). 

The structure ofthis polymer was confirmed by NMR-spectroscopy [157], Such copolymers can be formulated into a high performance positive photoresist. By comparison, a physical blend of a phenolic and poly-4-hydroxystyrene was not useful because of its slow kinetics of mixing. Therefore, the synthesis of a copolymer of both components yields a material with improved lithographic...

Frese et al. [38] studied the adsorption kinetics of mixed anionic/cationic surfactant systems, finding that net charge-neutral mixed micelles were formed. They found that the dynamic surface tension was higher than expected for small-surface ages, possibly due to an activation barrier associated with the mixed-micelle complexes.
