Phosphorescence

“Both timeless and timely, this is a book of wisdom and wonder” (Geraldine Brooks, Pulitzer Prize–winning author of March), a deeply personal exploration of what can sustain us through our darkest moments. “What has fascinated and sustained me over these last few years has been the notion that we have the ability to find, nurture, and carry our own inner, living light—a light to ward off the darkness. This is not about burning brightly; it’s about yielding a more simple phosphorescence—being luminous, having stored light for later use. Staying alive, remaining upright, even when lashed by doubt.” After surviving a difficult heartbreak and battle with cancer, acclaimed author and columnist Julia Baird began thinking deeply about how we, as people, persevere through the most challenging circumstances. She started to wonder, when we are overwhelmed by illness, loss or pain, or a tragedy outside our control: How can we keep putting one foot in front of the other? Baird went in search of the magic that fuels the light within—our own phosphorescence. In this stunning book, she reflects on the things that lit her way through the darkness, especially the surprising strength found in connecting with nature and not just experiencing awe and wonder about the world around her, but deliberately hunting it, daily. Baird also writes about crossbeams of resilience: nurturing friendships and a quiet faith, pursuing silence, fighting for what she believes in, the importance of feeling small, learning from her mother's example of stoic grace. She also explores how others nurture their inner light, interviewing the founder of the modern forest therapy movement in Tokyo, a jellyfish scientist in Tasmania, and a tattooed priest from Colorado, among others. Weaving together candid and moving memoir with deep research and reflections on nature and the world around her, Baird inspires readers to embrace new habits and to adopt a phosphorescent outlook on life, to illuminate ourselves and our days—even in the darkest times.

"After surviving a difficult heartbreak and battle with cancer, Julia Baird began to explore how she and others persevere through the most challenging circumstances life throws at us. She asks: when our world goes dark, when we are overwhelmed by illness or heartbreak, loss or pain, tragedy outside our control, how do we survive, stay alive and even bloom? She went in search of "the magic that will sustain us and fuel the light within - our own phosphorescence ". Phosphorescence can be found in nature - in glow worms, fireflies, flashlight fish, bioluminescent oceans; it is a phenomenon that allows creatures to give off light amidst darkness. Baird writes about the things that lit her way through the darkness: a connection to nature, friendships, her faith, experiencing awe, and other habits that changed her life. She also goes in search of how others nurture their inner light, interviewing the founder of the modern forest therapy movement in Tokyo, a jellyfish scientist in Tasmania, and a tattooed priest from Colorado, among others.

Significant progress has been made in recent years in quenched-phosphorescence oxygen sensing, particularly in the materials and applications of this detection technology that are open to commercialization, like uses in brain imaging and food packaging. Prompted by this, the editors have delivered a dedicated book that brings together these developments, provides a comprehensive overview of the different detection methodologies, and representative examples and applications. This book is intended to attract new researchers from various disciplines such as chemistry, physics, biology and medicine, stimulate further progress in the field and assist in developing new applications. Providing a concise summary at the cutting edge, this practical guide for current experts and new potential users will increase awareness of this versatile sensing technology.

Fluorescence and phosphorescence are proving to be extremely sensitive probes for elucidating conformation of proteins and nucleic acids and for studying molecular interactions. Newer instrumentation and techniques hold forth great promise for the future of these luminescence methods in biopolymer research. It must be noted, however, that the discovery that certain amino acids, purines, and pyrimidines emit fluorescence or phosphorescence is relatively recent, occurring within the last decade. Professor Konev is one of the pioneers in the application of these procedures to biopolymers and is highly qualified to write about this subject. This book, though written largely as a monograph of the author's own contributions, is also an excellent review of the subject. Of particular interest are the references to many important Russian papers in this field which have not been recognized in the Western literature. It is apparent from this book that fluorescence and phosphorescence methods are being used about as widely in Russia as elsewhere in the world and that we must not overlook these im portant contributions. Konev's studies on protein fluorescence have been widely recognized. It is of interest to learn about these and other of his applications. The last part of the book, which deals with fluorescence as a means to probe into the structure and conforma tion of macromolecules in intact cells, is most interesting. Aside from published symposia this book is the first written specifically about luminescence of biopolymers. Sidney Udenfriend Bethesda.

Fluorescence and Phosphorescence Spectroscopy: Physicochemical Principles and Practice deals with the physicochemical principles and applications of fluorescence and phosphorescence spectroscopy in experimental biology and chemistry. Topics covered include the absorption of light by molecules; instrumentation for the measurement of fluorescence and phosphorescence; solvent and acidity effects on electronic spectra; and polarization of fluorescence and phosphorescence. Comprised of four chapters, this book begins with a discussion on photophysical processes in isolated molecules and molecules in solution, paying particular attention to thermal equilibration of electronically excited molecules, phototautomerism, and coordination by metal ions. The next chapter describes the instrumentation for measuring fluorescence and phosphorescence, which consists essentially of a light source to electronically excite the sample; a monochromator to separate the light of desired energy from the source; a sample compartment; a second monochromator to isolate the sample's fluorescence energy from the excitation energy; a photodetector to translate the fluorescent light into an electrical signal; and a readout system such as a galvanometer or a recorder, coupled with an amplifier to determine the intensity of fluorescent light that is emitted. The final chapter is devoted to various applications of fluorescence and phosphorescence spectroscopy, including the analysis of organic and inorganic compounds. This monograph is written primarily for analytical chemists and biological scientists.
