"Textbook of Physical Pharmaceutics-II" offers an insightful journey into the realm of physical pharmaceutics, essential for both students and professionals. This comprehensive guide begins with an exploration of colloidal dispersions, delving into their classifications, properties, and the intricate behavior of colloidal particles. It provides a deep understanding of their optical, kinetic, and electrical properties, and the influence of electrolytes. The book then navigates through the complexities of Rheology, discussing Newtonian and Non-Newtonian systems, the Law of Flow, Kinematic Viscosity, and the effects of temperature on these systems. It also covers the unique properties of pseudoplastic, dilatant, and plastic materials, crucial for practical formulation aspects. A detailed section on the deformation of solids, including topics like the Heckel equation, stress, strain, and Elastic Modulus, offers valuable insights. The exploration of coarse dispersion sheds light on the formulation of suspensions and emulsions, their stability, and emulsification theories. In "Micromeretics," readers will discover the nuances of particle size and distribution, methods for determining particle size, shape, surface area, and their impacts on pharmaceutical formulations. The final chapter on drug stability covers reaction kinetics, factors influencing pharmaceutical degradation, stabilization techniques, and accelerated stability testing.
