    A crosslinkable side chain NLO-polymer of the bis-azobenzene type and an AB-type main chain NLO-polymer of the sulphonyl-tolane type have been synthesized and characterized with respect to their curing and electric poling : Manfred Eich, Siegfried Ohl, Rudolf Zentel, Heike Baumann, Leonie Goebel, Hartmut Krueger, Werner F. Photopolymers for imaging exhibit a high photosensitivity. The development of semiconductor lasers has resulted in a quantitative substitution of gas lasers by these sources emitting either in the near infrared (NIR) region ( or nm) or violet spectral part ( nm).

    This book is a greatly expanded edition of what has become one of the best known introductions to the principles, techniques and applications of optical holography. Where necessary, existing sections have been updated, and two new chapters have been by: Y. Zhao and T. Ikeda. Smart Light-Responsive Materials: Azobenzene-Containing Polymers and Liquid Crystals, Wiley, New Jersey (USA). , p. Author: B. Abbas, Y.T. Salman, M.S. EL-Dahr.

    Various components needed for optical backplane applications have been demonstrated from gelatin-based polymer integrated op[tic material. An array of waveguides have been realized with packaging density as high as channels per cm and loss of dB per cm.   The photochemical behavior of thin films and solutions of main chain nematic liquid crystalline trans-stilbene dicarboxylate polyesters (SDA) is discussed. Observation of spectral differences between solutions and thin films indicates the presence of chromophore aggregation. Hypochromic effects attributed to aggregation of chromophores become more pronounced upon thermal annealing Cited by: 1.

The unification of the star coupler and a modulator array is for backplane optical interconnects is under investigation. While some products are made with ceramics and metallic materials, most of the. products are made with high strength plastics such as acrylonitrile butadiene styrene (ABS) and polycarbonate (PC).

The literature review of photopolymers and 3D printing are mostly dealt in separate topics. A team of leading international experts provides the latest research results on such materials as new photoinitiators, hybrid photopolymers, and metallic carbon nanotube composites.

They also cover promising applications and prospective trends, including photonic crystals, microfluidic devices, biological scaffolds, metamaterials, waveguides, and functionalized hydrogels.

Photopolymers generally consist of a monomer, a photosensitive dye and an initiator. They can either be liquid or dry layer by: 2. Three-dimensional (3D) printing is a process of fabricating 3D objects by adding successive layers of materials (e.g. polymers) on top of each other.

Among various 3D printing approaches, the photochemical approach is extremely attractive as objects can be produced via photopolymerisation reactions of monome Emerging Investigators Most Downloaded Articles. Although most of applications of zeolites are closely related to their structural and chemical properties (i.e., type of zeolite, modification by ion exchange, and/or isomorphous substitution), size of zeolite crystals may play a crucial role in the mode and efficiency of their application as catalysts, adsorbents, and cation exchangers.

ACKNOWLEDGMENTS.The application of HABIs in photochromic windows is a daunting challenge. The radicals are excellent hydrogen abstractors and cannot develop media that lack abstractable hydrogen. Additionally, the color of the generated free radicals is weak, compared to real dyes, with extinction coefficients un, compared to dyes, such as crystal.
