Over the course of the last thirty years, the investigation of objects at the nano scale has rocketed. Nanoscale scientific research has not only powerfully affected the amount and orientation of knowledge, it has perhaps even more significantly redirected the ways in which much research work is carried out, changed scientists' methodology and reasoning processes, and influenced aspects of the structure of career trajectory and the functioning of scientific disciplines. This book identifies key historical moments and episodes in the birth and evolution of nanoscience, discusses the novel repertory of epistemological concerns of practitioners, and signals sociological propensities. As Galileo's telescope explored the moon's surface four hundred years ago, nano instrumentation now makes it possible to see the surface of single molecules. Moreover, practitioners are able to manipulate individual atoms and molecules at will to produce pre-designed synthetic materials, non-existent in nature. The combinatorial of heightened observational capacity and the tailoring of synthetic artificial materials exhibiting hitherto novel physical properties has widened and transformed the worlds of scientific knowledge and technical artefact. This book invites the question: to what extent does nanoscale scientific research constitute a kind of 'scientific revolution'?

This adaptation of Bentley's Textbook of Pharmaceutics follows the same goals as those of the previous edition, albeit in a new look. The content of the old edition has been updated and expanded and several new chapters, viz. Complexations, Stability Testing as per ICH Guidelines, Parenteral Formulations, New Drug Delivery Systems and Pilot Plant Manufacturing, have been included, with an intention to make the book more informative for the modern pharmacists. The book has six sections: Section I deals with the physicochemical principles. Two new chapters: Complexations and ICH Guidelines for Stability Testing, have been added to make it more informative. Section II conveys the information regarding pharmaceutical unit operations and processes. Section III describes the area of pharmaceutical practice. Extensive recent updates have been included in many chapters of this section. Two new chapters: Parenteral Formulations and New Drug Delivery Systems, have been added. Section IV contains radioactivity principles and applications. Section V deals with microbiology and animal products. Section VI contains the formulation and packaging aspects of pharmaceuticals. Pilot Plant Manufacturing concepts are added as a new chapter, which may be beneficial to readers to understand the art of designing of a plant from the pilot plant model.

Volume IV (2005) covers preparation, characterization of colloids, stability and interaction between pairs of particles, and in concentrated systems, their rheology and dynamics. This volume contains two chapters written, or co-authored by J. Lyklema and edited contributions by A.P.Philipse, H.P. van Leeuwen, M. Minor, A. Vrij, R.Tuinier and T. van Vliet. The volume is logically followed by Vol V, but is equally valuable as a stand alone reference. * Combined with part V, this volume completes the prestigious series Fundamentals of Interface and Colloid Science * Together with volume V this book provides a general physical chemical background to colloid science * Covers all aspects of particle colloids
