This book is about radioactive gases and particles which are dispersed in the environment, either from natural causes, or following nuclear test and accidental emissions. In the first five chapters of this book, the formation and properties of radioactive aerosols are described. Radon, which is of natural origin, is treated at some length, because its contribution to background radiation dose is important. Chapters describe the release of fission products, tritium and plutonium, in bomb tests and nuclear accidents. Particular reference is made to the pathways leading via agricultural products to man. The emphasis then changes to cover experimental aspects of radioactive aerosols. For example, problems in micrometeorology, the study of mass transfer, the mechanics of the human lung and uptake of lead from motor exhausts. Arthur Chamberlain has worked at the Atomic Energy Research Establishment at Harwell for thirty years as the leader of the Aerosol Group. It is a unique exposition and will be used by chemists, geographers, environmentalists as well as governments and other agencies involved in the nuclear debate.

The book covers the physical side of colloid science from the individual forces acting between submicron particles suspended in a liquid through the resulting equilibrium and dynamic properties. The relevant forces include Brownian motion, electrostatic repulsion, dispersion attraction, both attraction and repulsion due to soluble polymer, and viscous forces due to relative motion between the particles and the liquid. The balance among Brownian motion and the interparticle forces decides the questions of stability and phase behavior. Imposition of external fields produces complex effects, i.e. electrokinetic phenomena (electric field), sedimentation (gravitational field), diffusion (concentration/chemical potential gradient), and non-Newtonian rheology (shear field). The treatment aims to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterized model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of technological problems and design critical experiments. Some exposure to fluid mechanics, statistical mechanics, and electricity and magnetism is assumed, but each subject is reintroduced in a self-contained manner.

The fourth volume of Water Science Reviews presents three fascinating accounts of hydration phenomena in collodial systems. O. Fennell Evans and David Miller provide a reappraisal of the role of water in promoting amphiphilic assembly and structure. Donald Eagland's review of water-soluble polymers highlights those which show unique solution properties or where there is contention as to the explanation for the behaviour. The final review, from Kenneth Newman, deals with the hydration of surfaces, a topic of profound scientific and technological importance.

Formulation is a key step in the drug design process, where the active drug is combined with other substances that maximise the therapeutic potential, safety, and stability of the final medicinal product. Regulatory and quality demands, in addition to advances in processing technologies, result in growing challenges as well as possibilities for the field. Following on from Pharmaceutical Formulation, which covered traditional dosage forms such as tablets and capsules, this volume expands upon those formulations to cover a more diverse range of less common dosage forms. Novel routes of administration are covered from inhalational, dermal and transdermal formulations to ocular, oral suspensions, vaccines and nanoparticle drug delivery. The methods through which these formulations are processed and manufactured is also covered, providing essential knowledge to ensure quality, efficiency, and acceptable costing. Specialised Pharmaceutical Formulation is an essential, up to date resource for students and researchers working in academia and in the pharmaceutical industry and will equip readers with the ability to effectively and reliably produce products which can be approved, manufactured and made available to administer to patients.

Colloidal systems are important across a range of industries, such as the food, pharmaceutical, agrochemical, cosmetics, polymer, paint and oil industries, and form the basis of a wide range of products (eg cosmetics & toiletries, processed foodstuffs and photographic film). A detailed understanding of their formation, control and application is required in those industries, yet many new graduate or postgraduate chemists or chemical engineers have little or no direct experience of colloids.

Based on lectures given at the highly successful Bristol Colloid Centre Spring School, "Colloid Science: Principles, Methods and Applications" provides a thorough introduction to colloid science for industrial chemists, technologists and engineers. Lectures are collated and presented in a coherent and logical text on practical colloid science.

Practical scope of modern-day colloid science may be presented through a set of achievements and actual aims in preparation of novel materials and construction of novel technologies based on the foundation of knowledge on colloid systems. Yet many uncertainties pervade such field, ranging from the true potential of self-organising and self-assembling systems in the design of advanced material structures to numerous encounters over the question of practical viability between the tendencies to invest in knowledge on small-scale, molecular recognition processes and on spontaneous, large-scale mesoscopic formation phenomena. Albeit the existence of belief in advancement of knowledge on stereoscopic molecular recognition and molecular assembly manipulation that would eventually lead to perfect control inherent in the design of macroscopic structures, trial-and-error phenomena seem to permeate all relevant levels of organisation within practical colloid science approaches, from enzymatic, biomolecular recognition processes to the macroscopic design of novel functional outcomes. As genetic evolution teaches us, the major point of any design conductance is not elimination of inherent mistakes, but their productive acceptance, that is mutual coupling with development of improved and more richly organised contexts of knowledge. Within this perspective, inter-disciplinarity, that is constructive crossing of separate scientific areas of investigation, presents a necessary approach immanent in advancement of practical colloid science achievements in the coming era.
