Given the backdrop of intense interest and widespread discussion on the prospects of a hydrogen energy economy, this book aims to provide an authoritative and up-to-date scientific account of hydrogen generation using solar energy and renewable sources such as water. While the technological and economic aspects of solar hydrogen generation are evolving, the scientific principles underlying various solar-assisted water splitting schemes already have a firm footing. This book aims to expose a broad-based audience to these principles. This book spans the disciplines of solar energy conversion, electrochemistry, photochemistry, photoelectrochemistry, materials chemistry, device physics/engineering, and biology.

Candy, Josie and Buddy are three canine friends whose days are filled with fun and friendship at the local park. But their happy days are threatened when two bullies named Riff and Raff drive them from their park, perhaps for good. When the three timid friends return, unable to keep themselves away from their favourite spot, the bullies are determined to do them serious harm. This book teaches a valuable lesson that every child should learn, that if good friends stand together, bullies soon find out that they’re not as tough as they thought.

In this Christmas classic, six-year-old Sarah is determined to make the very best snowman possible, without the help of her older brother. When she sees her snowman, Max, come to life in a Christmas Eve frolic, her family refuses to believe her story. Although Sarah thinks she has proof that it was not all a dream, she decides in the end to keep the knowlege of her snowman friend as her very own special secret.

This book is dedicated to all relevant aspects of bulk fill materials and their uses in clinical practice. Today, we count over 30 different bulk fill materials, which can be used in the dental clinic. The composition of bulk fill materials and their different modes of application for moderate to large direct resin restorations placement are explained in this book. It is written by a group of international specialists and allows the reader to evaluate available materials, learn predictable techniques and evaluate long term survival as well as future developments. The book covers all fields related to the history of bulk fill composites, their composition and physical properties, and a step by step guide to their successful clinical applications. Practitioners will find it invaluable as a clinical manual and a good reference book.
