A needed resource for pharmaceutical scientists and cosmetic chemists, Essential Chemistry for Formulators of Semisolid and Liquid Dosages provides insight into the basic chemistry of mixing different phases and test methods for the stability study of nonsolid formulations. The book covers foundational surface/colloid chemistry, which forms the necessary background for making emulsions, suspensions, solutions, and nano drug delivery systems, and the chemistry of mixing, which is critical for further formulation of drug delivery systems into semisolid (gels, creams, lotions, and ointments) or liquid final dosages. Expanding on these foundational principles, this useful guide explores stability testing methods, such as particle size, rheological/viscosity, microscopy, and chemical, and closes with a valuable discussion of regulatory issues. Essential Chemistry for Formulators of Semisolid and Liquid Dosages offers scientists and students the foundation and practical guidance to make and analyze semisolid and liquid formulations. - Unique coverage of the underlying chemistry that makes possible stable dosages - Quality content written by experienced experts from the drug development industry - Valuable information for academic and industrial scientists developing topical and liquid dosage formulations for pharmaceutical as well as skin care and cosmetic products

By the 1950s CFCs had found further applications: as propellants in aerosol spray cans, in the manufacture of Styrofoam, and as vital industrial solvents. Then, in 1974, after millions of tons of CFCs had been released into the Earth's atmosphere, two scientists at the University of California demonstrated that these same "safe" wonder substances had altered the fundamental chemistry of the atmosphere and had begun to erode the ozone layer - the protective shield of all life on earth. The battle to restrict CFCs was fought in laboratories, at international conferences, and in the halls of Congress, pitting environmentalists intent on remedying what had become a global crisis against industrialists and government officials opposed to regulation. Finally, in 1987, fifty-seven nations signed the first global environmental treaty - the Montreal Protocol, which regulated the further production of CFCs and ushered in a new era of international cooperation on the environment.

Anesthesia Equipment: Principles and Applications, 2nd Edition, by Dr. Jan Ehrenwerth and Dr. James B. Eisenkraft, offers expert, highly visual, practical guidance on the full range of delivery systems and technology used in practice today. It equips you with the objective, informed answers you need to ensure optimal patient safety. "This is a comprehensive, up-to-date reference textbook covering all aspects of physics and equipment for the modern American anaesthetist. It may be helpful to those studying for American fellowship examinations but is not suited to preparation for the UK FRCA examinations." Reviewed by: I.Wrench on behalf of the British Journal of Anaesthesia, Feb 2014 Make informed decisions by expanding your understanding of the physical principles of equipment, the rationale for its use, delivery systems for inhalational anesthesia, systems monitoring, hazards and safety features, maintenance and quality assurance, special situations/equipment for non-routine adult anesthesia, and future directions for the field. Ensure patient safety with detailed advice on risk management and medicolegal implications of equipment use. Apply the most complete and up-to-date information available on machines, vaporizers, ventilators, breathing systems, vigilance, ergonomics, and simulation. Visualize the safe and effective use of equipment thanks to hundreds of full-color line drawings and photographs.

Fluorine: A Paradoxical Element, Volume Five, deals with the link between fluorine, humanity and the environment. It is divided into three main sections, including i) The history and developmental stages of fluorinated products, ii) Awareness of its importance in our environment, and iii) Recent contributions of fluoride products in medicine, pharmacy and our daily lives. Made engaging through interesting figures and accessible language, and written by a leading expert, Professor Tressaud, the book supports the work of scientists working in materials, toxicology and environmental science. It complements the author's edited series, Progress in Fluorine Science, covering recent advances. - Describes background and contextual information regarding the history, development of understanding, and applications of this important element - Explores the impacts of fluorine, both positive and negative, in the environment and biological systems - Includes applied, real-world information from agencies, such as CNRS, NASA, HWS and DOH
