Man Ray (1890–1976) was a polymath modernist, working in painting, sculpture, film, printmaking, and poetry. But it was his work in photography, with nude studies, fashion work, and portraiture that saw him pioneering a new chapter in the history of camerawork and art. With a wide-ranging collection of both his famous and lesser-known works, this monograph gives a vivid overview of Man Ray’s multifaceted practice and photographic legacy. It traces Ray from his artistic beginnings in New York through to his central role in the Parisian avant-garde, where he featured in the first Surrealist exhibition with Jean Arp, Max Ernst, André Masson, Joan Miró, and Pablo Picasso and produced such now iconic works as Noire et blanche and Le Violon d’Ingres. Through numerous examples of still life, portraiture, and beyond, we see how Ray constantly experimented with new techniques, pushing photography out of its documentary domain into ethereal, poetic expressions through multiple exposure, solarization, and the particular brand of photograms he wittily termed “rayography.”

X-Ray Crystallographic and Theoretical Investigations on Aromatic Compounds

X-Ray Crystallographic and Theoretical Investigations on Aromatic Compounds

This book targets a broad readership for young researchers(Postgraduate students) in X-ray crystallography and Quantum Chemistry as it contains a wide and comprehensive coverage of all important aspects of the subject including up-to- date survey of recent revolutionary advances. Molecular structure determination using crystallographic technique of pyrazolo 3,4-d] pyrimidines, naturally occurring drugs as well as synthetic molecular crystals has been discussed.The optimized structures and the electronic properties of the molecules using quantum mechanical methods have also been discussed and results have been compared with crystallographic data, which could enable one to understand and evaluate different quantum mechanical methods. It should be a valuable asset to established researchers in this area due to very detailed explanation of the behavior of aromatic - interactions on the basis of experimental and theoretical results. The crystallographic and theoretical investigations on some synthetic and natural drugs attract the research in the area of drug design using Molecular modeling of the reported compounds with suitable targets.

X-Ray Diffraction Imaging of Biological Cells

X-Ray Diffraction Imaging of Biological Cells

In this book, the author describes the development of the experimental diffraction setup and structural analysis of non-crystalline particles from material science and biology. Recent advances in X-ray free electron laser (XFEL)-coherent X-ray diffraction imaging (CXDI) experiments allow for the structural analysis of non-crystalline particles to a resolution of 7 nm, and to a resolution of 20 nm for biological materials. Now XFEL-CXDI marks the dawn of a new era in structural analys of non-crystalline particles with dimensions larger than 100 nm, which was quite impossible in the 20th century. To conduct CXDI experiments in both synchrotron and XFEL facilities, the author has developed apparatuses, named KOTOBUKI-1 and TAKASAGO-6 for cryogenic diffraction experiments on frozen-hydrated non-crystalline particles at around 66 K. At the synchrotron facility, cryogenic diffraction experiments dramatically reduce radiation damage of specimen particles and allow tomography CXDI experiments. In addition, in XFEL experiments, non-crystalline particles scattered on thin support membranes and flash-cooled can be used to efficiently increase the rate of XFEL pulses. The rate, which depends on the number density of scattered particles and the size of X-ray beams, is currently 20-90%, probably the world record in XFEL-CXDI experiments. The experiment setups and results are introduced in this book. The author has also developed software suitable for efficiently processing of diffraction patterns and retrieving electron density maps of specimen particles based on the diffraction theory used in CXDI.
