Book Description
Nitroxides are versatile small organic molecules possessing a stabilised free radical. With their unpaired electron spin they display a unique reactivity towards various environmental factors, enabling a diverse range of applications. They have uses as synthetic tools, such as catalysts or building blocks; imaging agents and probes in biomedicine and materials science; for medicinal antioxidant applications; and in energy storage. Polynitroxides (polymers bearing pendant nitroxide sidechains) have been used in organic radical batteries, oxidation catalysts and in exchange reactions for constructing complex architectures. Chapters in this book cover the synthesis of nitroxides, EPR studies and magnetic resonance applications, physiochemical studies, and applications including in batteries, imaging and organic synthesis. With contributions from leaders in the field, Nitroxides will be of interest to graduate students and researchers across chemistry, physics, biology and materials science.

Book Description
Extending the use of nitroxides as probes into more complex systems such as viable cells and whole animals requires greater knowledge of their interactions in functioning biological systems and appropriate model systems. Nitroxide Spin Labels: Reactions in Biology and Chemistry presents information essential for research in this area. Nitroxide research offers the promise of important new ways of measuring metabolism and will be useful in the diagnosis of important disease categories such as cancer, inflammation, and ischemia.

Book Description
What might the end of the world look like, to people who inhabit high mountains, whose lives are governed by the dependable revolution of the seasons? Perhaps the sun might slip beneath a western ridge one evening, and not return in the morning. In the first half of the 20th century, that terrifying prospect represented a mild version of hell. Real hell would be knowing in advance that it was going to happen. And so, revisiting a theme that Charles Ferdinand Ramuz had explored many times before in his fiction-notably in a short story that he wrote in 1912, on the eve of another war-he bestowed upon the villagers of Upper Saint-Martin the dreadful knowledge that the sun was sick and would soon expire, leaving them to die alone in the cold and the dark. The prophecy falls from the lips of the village sage and healer, Antoine Anzevui. The weather seems to bear him out. But the sun abandons those parts for a few months every year, so to accept the prophecy means to have faith in the prophet-to believe him when he says that the life-giving star won't return as expected in the spring. What holds for Upper Saint-Martin holds for the rest of the world, because in Ramuz's novels the village is the world and the world is the village Written in Fench as Si le soleil ne revenait pas and translated into English for the first time by Michelle Bailt-Jones, here are both the 1912 short story and the 1937 novel - What if the sun..."

Book Description
On sait, depuis l'avènement du laser, que l'intensité de la lumière est susceptible de modifier les propriétés optiques des matériaux. Cette optique « non linéaire » autorise l'interaction entre faisceaux lumineux par l'intermédiaire des milieux qu'ils traversent. Du fondamental à l'appliqué, cet ouvrage aborde la diversité de ces aspects « matériaux » et « fonctions ».

Book Description
Depuis l’invention des lasers, l’optique non linéaire n’a cessé de se développer dans de multiples directions. Fondée sur la réponse non linéaire de matériaux soumis à des ondes électromagnétiques intenses, elle permet la génération de seconde harmonique ou de nouvelles fréquences par effets paramétriques, ou encore de modifi...
