The Porphyrin Handbook, Volume 18: Multiporphyrins, Multiphthalocyanines and Arrays provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the results obtained in the research concerning the properties and formation of a class of metal phthalocyanine derivatives containing of two macrocyclic units. This text then examines the luminescence and photophysical data of multiporphyrin systems in which the chromophore centers are held together by weak, medium, or strong bonding interactions. Other chapters consider the intensive electronic absorption and circular dichroism properties of chiral phthalocyanines. This book discusses as well the chemistry porphyrin and corrin systems. The final chapter deals with geoporphyrins or sedimentary porphyrins, which are the most abundant porphyrin derivatives on earth. This book is a valuable resource for research scientists, engineers, and clinicians.

The Porphyrin Handbook, Volume 14: Medical Aspects of Porphyrins provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into 12 chapters, this volume begins with an overview of the underlying diagnostic features, mechanisms, and available treatments of erythropoietic disorders due to defective heme biosynthesis. This text then examines the physiopathology of acute intermittent porphyria, which is transmitted as autosomal dominant disorders with incomplete penetrance. Other chapters consider the main characteristics of congenital erythropoietic porphyria, which includes an increased synthesis, accumulation, ad excretion of porphyrins. This book discusses as well the biochemistry, pathophysiology, and clinical features of variegate porphyria in the light of several essential advances in the understanding, management, and diagnosis of variegate porphyria. The final chapter deals with the legal use of herbal and complementary medicines. This book is a valuable resource for research scientists, engineers, and clinicians.

This is the first set of Handbook of Porphyrin Science.Porphyrins, phthalocyanines and their numerous analogues and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorophyll); they are also excellent ligands that can coordinate with almost every metal in the Periodic Table. Grounded in natural systems, porphyrins are incredibly versatile and can be modified in many ways; each new modification yields derivatives demonstrated new chemistry, physics and biology, with a vast array of medicinal and technical applications.As porphyrins are currently employed as platforms for study of theoretical principles and applications in a wide variety of fields, the Handbook of Porphyrin Science represents a timely ongoing series dealing in detail with the synthesis, chemistry, physicochemical and medical properties and applications of polypyrrole macrocycles. Professors Karl Kadish, Kevin Smith and Roger Guilard are internationally recognized experts in the research field of porphyrins, each having his own separate area of expertise in the field. Between them, they have published over 1500 peer-reviewed papers and edited more than three dozen books on diverse topics of porphyrins and phthalocyanines. In assembling the new volumes of this unique Handbook, they have selected and attracted the very best scientists in each sub-discipline as contributing authors of the chaptersThis Handbook will prove to be a modern authoritative treatise on the subject as it is a collection of up-to-date works by world-renowned experts in the field. Complete with hundreds of figures, tables and structural formulas, and thousands of literature citations, all researchers and graduate students in this field will find the Handbook of Porphyrin Science an essential, major reference source for many years to come.

The Porphyrin Handbook, Volume 16: Phthalocyanines: Spectroscopic and Electrochemical Characterization provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the photophysical properties of phthalocyanines that are important in relation to photosensitizers in photodynamic therapy, photoconductor, solar cells, and artificial photosynthesis. This text then describe how the data obtained from magnetic circular dichroism spectroscopy has provided the critical information required to describe the excited and ground state degeneracies of main group metallophthalocyanines complexes. Other chapters consider the electrocatalysis by electrodes modified with phthalocyanine sensors and complexes. This book discusses as well the properties of phthalocyanines and of their complexes. The final chapter deals with the experiments with organic pigment thin films. This book is a valuable resource for research scientists, engineers, and clinicians.

How I Feel books help children ages 2-6 recognize and identify their emotions and give them a vocabulary to describe what they are feeling. If children can name an emotion, they are on their way to understanding it. And when children can talk about what they are feeling, their parents will be better able to help them.Features: -- 8 x 8 24-page hardcover or -- softcover full-color picture book -- Each book includes an activity card and reusable stickers -- Question-answer format stimulates conversation between parent and child

The Porphyrins, Volume I: Structure and Synthesis, Part Ais the first in a series of seven volumes and covers topics like nomenclature, purification, and structural determination of porphyrins, metalloporphyrins, and other related compounds. This volume serves to be a critical review of the topics covered and presents a complete and comprehensible discussion on the chemistry and biochemistry of porphyrins. The chapters in the text tackle the history and geochemistry of porphyrins and related systems. Also covered and discussed in the chapters is the synthesis of porphyrins from mono-, di-, and tetrapyrrolic intermediates. The isolation and modification of porphyrins from natural sources are also discussed. Other related compounds are also included, such as metallo-, aza-, and N-methylporphyrins, and their synthesis and properties. This book is a good introduction and reference for students studying in the fields of chemistry and biochemistry.
