Polymeric Liquid Crystals
This book originated in the Proceedings of the Second Symposium on Polymeric Liquid Crystals held by the Division of Polymer Chemistry in the framework of the 1983 Fall Meeting of the American Chemical Society. At the First Symposium in 1977, the literature in this field could be encompassed in a single volume. To day, that is no longer possible. The field of Polymeric Liquid Crystals grew, and continues to grow, at a very rapid pace. At present, we know of every major mesophase in its polymeric form and of polymeric glasses, elastomers and fluids in their liquid crystalline form. Every year, new polymeric mesophases are being discovered. The aim of this book is to go beyond a compilation of...
Adhesive Chemistry
Since the first symposium on Recent Advances in Adhesion, held September, 1971 in Washington, D. C. , this Division of the American Chemical Society has continuously sponsored several symposia on adhesion and adhesives. The chemists have gradually realized the importance of adhesion in various fields of science and technology. During these years, the science of adhesion has steadily grown along with progress in surface science and fracture mechanics. Moreover, new adhesives have been invented and applied in actual structures, for example, structural and aerospace adhesives. In response to socio-economic demands, new forms of adhesives have been introduced to combat the problems of pollution ...
Polymeric Materials in Medication
The art of using chemical agents for medication dates back into antiquity, although most of the earliest examples used plants, herbs, and other natural materials. The old Egyptian medical papyri, which date from before 1400 B. C. , contain dozens of examples of such medicinal plants and animal extracts. In the Old Testament of the Bible, we can find references to using oil to soften the skin and sores (Isaiah 1:6), the use of tree leaves for medicine (Ezekiel 47:12) and various medical balms (Jeremiah 8:22). Not all these recipes were effective in curing the ailments for which they were used and sometimes the treatment was worse than the disease. Nevertheless, the art of using chemical deriv...
Operation Barbarossa and its Aftermath
The 1941 invasion of the Soviet Union, codenamed Operation Barbarossa, remains one of Nazi Germany’s most significant military campaigns. Executed by Hitler’s Wehrmacht army, this event saw troops from all over Europe defeat the Red Army and temporarily colonize large swathes of Eastern Europe, ultimately laying the groundwork for the Holocaust. In this illuminating re-examination of this multifaceted event, Operation Barbarossa and its Aftermath refocuses our attention on the multiethnic nature of the campaign, shedding light on the role of soldiers from Slovakia, Italy, Romania, and Spain as well as other important issues. This volume highlights how viewing Operation Barbarossa as a multiethnic campaign, rather than a strictly German-Russian conflict, offers new ways of understanding the Holocaust, World War II and the history of European collaboration.
Liquid Crystalline Order in Polymers
Liquid Crystalline Order in Polymers examines the topic of liquid crystalline order in systems containing rigid synthetic macromolecular chains. Each chapter of the book provides a review of one important area of the field. Chapter 1 discusses scattering in polymer systems with liquid crystalline order. It also introduces the field of liquid crystals. Chapter 2 treats the origin of liquid crystalline order in macromolecules by describing the in-depth study of conformation of such macromolecules in their unassociated state. The chapters that follow describe successively the liquid crystalline order in polymers with mesogenic side groups and rigid backbones, in polypeptides, and in block copolymers. Chapter 7 discusses the rheology of such systems. The last two chapters examine liquid crystalline order in biological materials and mesomorphic order in the realm of polymers with inorganic backbones. This book is intended to provide the polymer scientist, the materials scientist, and the biologist with a valuable source of information.
