The book illustrates the fascinating world of the different forms of water - from ice and snow to liquid water. The water molecule, H2O, is the second most common molecule in the Universe (behind hydrogen, H2) and ice is the most abundant solid material. Snow and ice appear in a countless large number of different shapes and with properties which can be quite different. Detailed knowledge of the properties of snow is of great importance for the Sami people involved in reindeer herding and several hundred names are used to characterize the different types. The properties of ice and liquid water are very special and unique in several respects. In contrast to most other substances, the density of ice is lower than that of liquid water, which has many very important consequences in our daily life. Water plays a unique role in chemistry and although tremendous research has been spent on this seemingly simple substance, there are still many unsolved questions about the structure of liquid water. The special properties of water are due to hydrogen bonding between the H2O molecules, and this book may be seen as a tribute to the hydrogen bond. The general properties of the hydrogen bond are treated in three separate papers. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together. -- Provided by publisher.

The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment, and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together.The unique properties of water are of great importance in our daily life. The origin of these special properties is often not recognized. Even among chemists and physicists, the fundamental facts are not always known. In spite of very active research, there are still many questions to be answered about the structure of liquid water, for instance.The book differs from most books on water as it covers basic facts about structure and properties as well as the influence of these properties in our daily life. Why does ice float on water? Why is the maximum density of water at 4°C? The beauty of snow crystals is amply illustrated, and many of the pictures are unique.

As one of the typical intermolecular interactions, hydrogen-bonding plays a significant role in molecular structure and function. When the hydrogen bond research system is connected with the photon, the hydrogen-bonding effect turns to an excited-state one influencing photochemistry, photobiology, and photophysics. Thus, the hydrogen bond in an excited state is a key topic for understanding the excited-state properties, especially for optoelectronic or luminescent materials.The approaches presented in this book include quantum chemical calculation, molecular dynamics simulation and ultrafast spectroscopy, which are strong tools to investigate the hydrogen bond. Unlike other existing titles, this book combines theoretical calculations and experiments to explore the nature of excited-state hydrogen bonds. By using these methods, more details and faster processes involved in excited-state dynamics of hydrogen bond are explored.This highly interdisciplinary book provides an overview of leading hydrogen bond research. It is essential reading for faculties and students in researching photochemistry, photobiology and photophysics, as well as novel optoelectronic materials, fluorescence probes and photocatalysts. It will also guide research beginners to getting a quick start within this field.
Breathtaking photography and fascinating facts about snow crystals “will instill appreciation for these tiny, cool objects” in both children and adults (The Washington Post). How do snow crystals form? What shapes can they take? Is it true that there are no two snow crystals alike? These questions and more are answered in this visually stunning exploration of the science of snow. Perfect for reading on winter days, the book features photos of real snow crystals in all their beautiful diversity. Snowflake-catching instructions are also included! “Settle down in a comfy chair. . . . By the end, you’ll be hoping there’s a day when you can follow the careful directions for catching and viewing snow crystals.” —Chicago Tribune “The clear and direct narrative takes readers into the clouds to explain snow-crystal formation...and then zooms in on the actual crystals. Sure to get young scientists outside in the cold.” —Kirkus Reviews “Nature photographer Cassino’s gallery of snow crystals is [a] riveting exhibition.” —Bulletin of the Center for Children’s Books (starred review)
