N-Heterocyclic Carbene-Catalyzed Synthesis of C–N Atropisomers and Heteroatom Chiral Molecules
Asymmetric catalysis has received worldwide interest due to the increasing demand for optically pure compounds in pharmaceuticals, agrochemicals, natural products, and materials science. Traditionally, research in this ... -
Studies on film boiling
A boundary layer analysis is made for the two-phase flow problem in laminar film boiling under various situations. The situations considered are: Film boiling on horizontal cylinders and spheres Forced convection film ... -
Stochhastic chatter theory
The machining process on modern machine tools is a dynamic phenomenon having cause-and-effect interaction under stochastic environments. With a steady increase in utilization parameters, intensive vibrations occur, which ... -
Casing boundary layer decelopment in axial impellers with TIP clearence
Casing wall boundary layers are heavily skewed under the action of secondary and tip clearance flows, relative wall motion and the transverse forces associated with the blade rows. The growth of the casing boundary layers ... -
studies in terpenoids
Chapter 1 This chapter is devoted to the isolation and structure elucidation of some natural products which are important as drugs in the Indian system of medicine. Section 1 (i): The chemistry of Barringtonia species is ... -
Transition metal complexes in the structure, streochemistry and synthesis
The thesis entitled "Transition Metal Complexes in Structure, Stereochemistry and Synthesis of Some Naturally Occurring Compounds" consists mainly of two chapters. The first chapter is divided into two parts, and Part I ... -
