Natural Substances for Cancer Prevention explores in detail how numerous investigations in chemical biology and molecular biology have established strong scientific evidence demonstrating how the properties of naturally occurring bioactive chemicals hamper all stages of cancers (from initiation to metastasis). Accordingly, important goals for cancer prevention are the modification of our dietary habits and an increase in the intake of more anticancer-related natural substances. More significantly, the bioactive chemicals presented in the functional foods should be readily available, inexpensive, non-toxic, and nutritional.

A fascinating collection of the pictures, figures, and diagrams that chemists create to explain their craft

In A Chemical History Tour, Arthur Greenberg took readers on a wild romp through the history of chemistry, introducing the unique characters, sometimes bizarre theories, and novel experiments that ultimately produced the modern science. Now Greenberg returns with more tales of chemistry glory, lovingly chronicling the extraordinary artwork that alchemists and chemists have produced in their pursuit of understanding the nature of matter in The Art of Chemistry: Myths, Medicines, and Materials.

The Art of Chemistry employs 187 figures (including 16 full-color plates) to illuminate 72 essays on the mythical origins, wondrous experiments, and adventurous explorers in the annals of chemistry. Greenberg divides his delightful study into eight sections:

• Spiritual and Mythological Roots
• Stills, Cupels, and Weapons
• Medicines, Purges, and Ointments
• An Emerging Science
• Two Revolutions in France
• A Young Country and a Young Theory
• Specialization and Systemization
• Some Fun

Each section tracks chemistry’s incremental progress from myth to modern science, featuring the figures and diagrams that early chemists used to explain their craft. Along the way, readers will meet the deadly basilisk and the fabulous phoenix that populated the lore of pre-modern chemistry, learn the contributions to chemistry of the American natural philosopher Benjamin Franklin, and encounter Antoine Lavoisier, the father of modern chemistry and perhaps France’s greatest economist.

Greenberg also examines our fundamental connections with science through two personal essays, one on an adolescent friend who improbably (but perhaps inevitably) became a world-renowned entomology professor and the other on his quest to discover his own chemical heritage. The Art of Chemistry is sure to inform and entertain anyone interested in our eternal quest to know the natural world.

Prefaces are like speeches before the c- tain; they make even the most self-forgetful performers seem self-conscious. - William Allen Neilson The study of phenomena and processes at the phase boundaries of m- ter is the realm of the surface scientist. The tools of his trade are drawn from across the spectrum of the various scienti?c disciplines. It is therefore interesting that, in investigating the properties of such boundaries, the s- facist must transcend the interdisciplinary boundaries between the subjects themselves. In this respect, he harkens back to the days of renaissance man, when knowledge knew no boundaries, and was pursued simply for its own sake, in the spirit of enlightenment. Chemisorption is a gas-solid interface problem, involving the inter- tion of a gas atom with a solid surface via a charge-transfer process, during which a chemical bond is formed. Because of its importance in such areas as catalysis and electronic-device fabrication, the subject of chemisorption is of interest to a wide range of surfacists in physics, chemistry, materials science, as well as chemical and electronic engineering. As a result, a vast lite- ture has been created, though, despite this situation, there is a surprising scarcity of books on the subject. Moreover, those that are available tend to be experimentally oriented, such as, Chemisorption: An Experimental - proach (Wedler 1976). On the theoretical side, The Chemisorption Bond (Clark 1974) provides a good introduction, but is limited in not describing the more advanced techniques presently in use.

This book closes a current gap by providing the scientific basis for consumer exposure assessment in the context of regulatory risk assessment. Risk is defined as the likelihood of an event occurring and the severity of its effects. The margin between the dose that leads to toxic effects and the actual dose of a chemical is identified by estimating population exposure. The objective of this book is to provide an introduction into the scientific principles of consumer exposure assessment, and to describe the methods used to estimate doses of chemicals, the statistics applied and computer tools needed. This is presented through the backgrounds of the special fields in exposure analysis, such as exposure via food and by the use of consumer products, toys, clothing and other items. As a general concept, human exposure is also understood to include exposure via the environment and from the work setting. In this context, the specific features of consumer exposure are pointed out and put into the context of regulation, in particular food safety, chemicals safety (REACh) and consumer product safety. The book is structured into three parts: The first part deals with the general concepts of consumer exposure as part of the overall risk analysis framework of risk characterization, risk assessment and risk communication. It describes the three basic features of exposure assessment (i) the exposure scenario (ii) the exposure model and (iii) the exposure parameters, addressing external and internal exposure. Also, the statistical presentation of data to characterize populations, in connection with variability, uncertainty and quality of information and the presentation of exposure evaluation results is described. The second part deals with the specific issues of exposure assessment, exposure via food consumption, exposure from use of consumer products, household products, toys, cosmetic products, textiles, pesticides and others. This part also covers methods for acquisition of data for exposure estimations, including the relevant information from regulations needed to perform an accurate exposure assessment. The third part portrays a prospect for further needs in the development and improvement of consumer exposure assessment, as well as international activities and descriptions of the work of institutions that are involved in exposure assessment on the regulatory and scientific level. And conversely, it creates the rationale for the exposure assessment details necessary to satisfy regulatory needs such as derivation of upper limits and risk management issues.
