This book highlights the dynamical behavior of self-similar waves in asymmetric dual-core waveguides. The proposed dual-core waveguide consists of two closely spaced adjoining fibers in which one fiber is active and the other is passive. Due to the linear coupling between them, the dynamics of the wave propagating through the passive core can be controlled by manipulating the dynamics of the wave propagating in the active core. The optimal pulse compression or amplification of these waves as the length of the fiber tends to infinity is presented. The exact Mobius transform self-similar solutions that propagate through these waveguides self-similarly are subject to simple scaling rules. The book includes experiments conducted to corroborate the analytical predictions.

Nowadays, chirality is widely accepted as an important factor in molecular recognition processes and the biological activity of many pharmaceutical drugs and agrochemicals; this is confirmed by the continuous need for synthetic methods which lead to single or enriched enantiomers of such compounds. By presenting a review of the various and more recently developed approaches for both metal-transition and organocatalysis, this volume describes the development of "greener" asymmetric reactions which preserve stereoselectivity. The author summarizes the impressive amount of research that has been gathered within this field into three chapters focusing on: i)the search of alternative catalysts, ii) alternative solvents, and iii) alternative synthetic strategies and processes. For each topic, the fundamentals and some valuable applications are discussed.
