BOOKS chapters, has complemented her considerable expertise on the subject by assembling a list of able contributors. Together they provide a comprehensive description of the powerful nonperturbative optical technique of surface light scattering (SLS). SLS can be used u n d e r e x t r e m e temperature and pressure conditions to m e a s u r e s u r f a c e t e n s i o n from > 300 m N / m for mercury to < 1CT4 mN/m for microemulsion systems. It also provides information about the surface a n d bulk viscoelasticity of the coexisting phases. The book is divided into four parts. P a r t I describes the general principles of t h e technique. P a r t II p r e sents the many contexts for application of SLS, including simple liquids, surface critical opalescence, liquid crystals, polymer solutions, adsorbed m o n o l a y e r s , lipid b i l a y e r s , microemulsions, thin liquid (soap) films, and the crystal-melt interface. P a r t III discusses several complementary techniques: externally excited surface w a v e s , light r e f l e c t i v i t y a n d ellipsometry, X-ray and neutron scattering from liquid surfaces, and fluorescence methods at the l i q u i d -
vapor interface. Finally, P a r t TV contains a single chapter on light scattering by solid surfaces and surface characterization. SLS is a timely topic, and readers whose work lies in surfactant science a n d surface c h a r a c t e r i z a t i o n could indeed benefit from t h e technique. For readers interested in developing t h e SLS m e t h o d for t h e i r s t u d i e s , P a r t I provides the fundamental e q u a t i o n s , e x p e r i m e n t a l steps, insight, and advice needed to initiate an SLS experiment. C h a p t e r 1, which d e s c r i b e s t h e h i s t o r i c a l d e v e l o p m e n t of SLS, is fairly accessible, b u t some of t h e subtle points in the ensuing chapters require careful reading to appreciate the delicate and intricate details involved in the technique. More importantly, the r e a d e r should be aware that the book was written mainly by physicists. Therefore, much of the terminology could be unfamiliar to analytical chemists or colloid scientists. Perhaps a simple gauge for the reader is to ask the following quest i o n s w i t h r e g a r d to t h e first two equations in Chapter 2: Are you familiar with writing a displacement

into a sum of Fourier components? Do you know what capillarity is? A reader who is not sure may find that the most important chapters on the principles of SLS (Chapters 2-6) will require substantial extra work before t h e t e c h n i q u e can be m a s tered. For example, a short section in C h a p t e r 3 summarizes some of the Born and Wolf calculations (Principles of Optics, P e r g a m o n P r e s s , 1959). Chemists who have not come across Born and Wolf (and I presume most have not) would need some preparation before tackling the physics of SLS. The principles chapters should be studied w i t h the original references for a more t h o r o u g h u n d e r standing of the details. In P a r t II on a p p l i c a t i o n s , t h e c h a p t e r s , as in P a r t I, are mostly w r i t t e n by Langevin. The chapters on simple liquids, surface critical opalescence (J.

Transuranium Elements: A Half Century
D
eveloped from an international symposium commemorating the 50th Anniversary of the discovery of transuranium elements, this volume honors the chemists, physicists, materials scientists, and engineers who were the pioneers of transuranium research in the 1940s. Opening with a comprehensive review by Glenn T. Seaborg of the discovery of transuranium elements and his perspective on the future of the field, the volume offers an outline of the discoveries of transuranium elements and of the chemical foundations of transuranium research, written by the pioneers themselves. The volume also emphasizes contemporary research with articles on nuclear chemistry and physics; spectroscopy, photophysics, and photochemistry; inorganic and analytical chemistry; materials physics and chemistry: and solution and environmental chemistry of the transuranium elements.
