This book was released on 1995 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ground state electronic structure and optical spectra of Ce(III), Ce(IV) and Eu(III) octaethyl bisporphyrin dimers (double deckers) are examined using the Intermediate Neglect of Differential Overlap (INDO/S) model and multireference configuration interaction (MRCI). The low energy electronic excited states of the dimers are interpreted in terms of their monomer contributions, and the charge transfer and excitonic character of the transitions are analyzed. Particular attention is focused on the nature of the near infrared band (NIR) that characterizes the spectra of the electron deficient bisporphyrin dimers, justifying its shift to higher energy as the ionic radii of the central ion decreases, and relating its broadness to the contribution of closely spaced electronic transitions that become allowed through vibronic coupling. The influence of an electric perturbation on the dimeric Ce(IV) and Eu(III) structures is used to explain their conductivity. The results are compared to those derived from resonant Raman spectroscopy, which show the importance of the vibrational fine structure in the assignment of the NIR band. jg p4.

Download or read book Combinatorial Chemistry written by Stephen R. Wilson and published by John Wiley & Sons. This book was released on 1997-03-28 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new time-saving revolution in drug discovery. Combinatorial chemistry, a method for synthesizing millions of chemical compounds much faster than usual, is becoming one of the most useful technical tools available to chemists and researchers working today. Using current advances in computer and laboratory techniques, combinatorial chemistry has freed professionals from the drudgery of piecemeal experimental work and opened new creative possibilities for experimentation. Combinatorial Chemistry: Synthesis and Application details critical aspects of the technique, featuring the work of some of the world's leading chemists, many of whom played a key role in its development. Including examples of both solution-phase and solid-phase approaches as well as the full complement of organic chemistry technologies currently available, the book describes: * Concepts and terms of combinatorial chemistry * Polymer-supported synthesis of organic compounds * Macro beads as microreactors * Solid-phase methods in combinatorial chemistry * Encoded combinatorial libraries, including Rf-encoding of synthesis beads * Strategies for combinatorial libraries of oligosaccharides * Combinatorial libraries of peptides, proteins, and antibodies using biological systems. While combinatorial chemistry originated in peptide chemistry, this volume has deliberately focused on nonpeptide organic applications, illustrating the technique's wide uses. Combinatorial Chemistry introduces organic, medicinal, and pharmaceutical chemists as well as biochemists to this exciting, cost-effective, and practical technique, which has unlocked creative potential for the next millennium.

Download or read book Nanohybrids written by Gaurav Sharma and published by Materials Research Forum LLC. This book was released on 2021-01-20 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers preparation, designing and utilization of nanohybrid materials for biomedical applications. These materials can improve the effectiveness of drugs, promote high cell growth in new scaffolds, and lead to biodegradable surgical sutures. The use of hybrid magneto-plasmonic nanoparticles may lead to non-invasive therapies. The most promising materials are based on silica nanostructures, polymers, bioresorbable metals, liposomes, biopolymeric electrospun nanofibers, graphene, and gelatin. Much research focuses on the development of biomaterials for cell regeneration and wound healing applications. Keywords: Biomedical Materials, Cell Growth, Cell Regeneration, Wound Healing, Surgical Sutures, Non-invasive Therapies , Drug Transport, Tissue Engineering, Cardiovascular Implants, Fracture Repair Implants, Biodegradable Materials, Hybrid Magneto-plasmonic Nanoparticles, Silica Nanostructures, Polymers, Bioresorbable Metals, Liposomes, Biopolymeric Electrospun Nanofibers, Graphene, Gelatin-based Hydrogels.
