NMR of Liquid Crystal Dendrimers
Dendrimers are hyperbranched molecules with well-defined nanometer-scale dimensions. Important technological applications of these systems, both in biomedicine and materials science, have been recently proposed. Liquid crystal dendrimers are fascinating materials that combine the characteristics of dendrimers with the anisotropic physical behaviour and molecular self-organization typical of liquid crystals. This unique association of physical and chemical properties, together with the possibility of multi-selective functionalization put forward by dendrimers, opens new perspectives for applications. Nuclear magnetic resonance (NMR) is a powerful experimental technique applied in materials sc...
Ionic Liquid Crystals
In this book we have collected a series of state-of-the art papers written by specialists in the field of ionic liquid crystals (ILCs) to address key questions concerning the synthesis, properties, and applications of ILCs. New compounds exhibiting ionic liquid crystalline phases are presented, both of calamitic as well as discotic type. Their dynamic and structural properties have been investigated with a series of experimental techniques including differential scanning calorimetry, polarized optical spectroscopy, X-ray scattering, and nuclear magnetic resonance, impedance spectroscopy to mention but a few. Moreover, computer simulations using both fully atomistic and highly coarse-grained force fields have been presented, offering an invaluable microscopic view of the structure and dynamics of these fascinating materials.
Gunpowder, Explosives and the State
Gunpowder studies are still in their infancy despite the long-standing civil and military importance of this explosive since its discovery in China in the mid-ninth century AD. In this second volume by contributors who meet regularly at symposia of the International Committee for the History of Technology (ICOHTEC), the research is again rooted in the investigation of the technology of explosives manufacture, but the fact that the chapters range in scope from the Old World to the New, from sources of raw materials in south-east Asia to the complications of manufacture in the West, shows that the story is more than the simple one of how an intriguing product was made. This volume is the first...
Nematic and Cholesteric Liquid Crystals
Liquid crystals allow us to perform experiments that provide insight into fundamental problems of modern physics, such as phase transitions, frustration, elasticity, hydrodynamics, defects, growth phenomena, and optics (linear and non linear). This excellent volume meets the need for an up-to-date text on liquid crystals.Nematic and Cholesteric Liq
Essays on Paula Rego
In these powerful and stylishly written essays, Maria Manuel Lisboa dissects the work of Paula Rego, the Portuguese-born artist considered one of the greatest artists of modern times. Focusing primarily on Rego's work since the 1980s, Lisboa explores the complex relationships between violence and nurturing, power and impotence, politics and the family that run through Rego's art. Taking a historicist approach to the evolution of the artist's work, Lisboa embeds the works within Rego's personal history as well as Portugal's (and indeed other nations') stories, and reveals the interrelationship between political significance and the raw emotion that lies at the heart of Rego's uncompromising i...
The Shaping of Africa
This title was first published in 2002. When did Africa emerge as a continent in the European mind? This book aims to trace the origins of the idea of Africa and its evolution in Renaissance thought. Particular attention is given to the relationship between the process of acquiring knowledge through travel and exploration, and its representation within a discourse which also includes previously acquired cosmographical elements. Among the themes investigated are: How did the image of Africa evolve from the conception of a symbolic space to a Euclidean representation? How did the Renaissance rediscovery of Antiquity interact with the Portuguese discoveries along the African coast? And once Africa was circumnavigated, how was the inner landmass depicted in the absence of first-hand knowledge? Also, overall, in this whole process what was the interplay of myth and reality?
A Companion to Portuguese Literature
This companion volume offers an introduction to European Portuguese literature for university-level readers. It consists of a chronological overview of Portuguese literature from the twelfth century to the present day, by some of the most distinguished literary scholars of recent years, leading into substantial essays centred on major authors, genres or periods, and a study of the history of translations. It does not attempt an encyclopaedic coverage of Portuguese literature, but provides essential chronological and bibliographical information on all major authors and genres, with more extensive treatment of key works and literary figures, and a particular focus on the modern period. It is u...
