Applied crystallography

Crystallography is the branch of science that deals with the geometric forms of crystals. It is the experimental sience of determining the arrangement of atoms in the crystalline solids. The external morphology of crystals reflects their growth rates in different directions. These directions remain constant during the course of the growth process, and are represented mathematically as the normal to sets of parallel planes that are imagined as being added on as growth proceeds. The book "Applied Crystallography" is divided into eighth chapters. the concept of crystallographic based optical filters has been introduced in first chapter. In second chapter, we focus on two-dimensional photonic crystal devices and emphasize their use as building blocks in photonic integrated circuits with applications in high bandwidth optical communication systems. Third chapter presents a new photo-acoustic gas detection scheme based on a widely tunable coupled-cavity photonic crystal laser operating around 1900 nm. We present experimental and theoretical works on the applications of the magneto-optical trap by modifying the trap conditions, which is termed as an asymmetric magneto-optical trap (AMOT) in fourth chapter. The objective of fifth chapter is to investigate the effect of the applied electric field and phase order (before the polymerization) on the alignment on the polymer network formed in the FLC host. Sixth chapter discusses the F1 catalyst for polymerization of olefin. The use of two-photonpolymerization fabrication of doped microstructures has been discussed in seventh chapter. Various hypotheses about the mechanism of particle formation in emulsion polymerization have been discussed in last chapter.
