This volume, occasioned by the centenary of the Fritz Haber Institute, formerly the Institute for Physical Chemistry and Electrochemistry, covers the institute's scientific and institutional history from its founding until the present. The institute was among the earliest established by the Kaiser Wilhelm Society, and its inauguration was one of the first steps in the development of Berlin-Dahlem into a center for scientific research. Its establishment was made possible by an endowment from Leopold Koppel, granted on the condition that Fritz Haber, well-known for his discovery of a method to synthesize ammonia from its elements, be made its director. The history of the institute has largely ...
The study of intermolecular forces began over one hundred years ago in 1873 with the famous thesis of van der Waals. In recent decades, knowledge of this field has expanded due to intensive research into both its theoretical and the experimental aspects. This is particularly true for the type of very strong cohesive force stressed in 1920 by Latimer and Rodebush: the hydrogen bond, a phenomenon already outlined in 1912 by Moore and Winemill. Hydrogen bonds exert a profound influence on most of the physical and chemical properties of the materials in which they are formed. Not only do they govern viscosity and electrical conductivity, they also intervene in the chemical reaction path which de...
This book shows the different molecular devices used for solar energy conversion and storage and the important characterization techniques for this kind of device. It has five chapters describing representative molecule-based solar cells, such as organic solar cells, dye-sensitized solar cells and hybrid solar cells (perovskite solar cell and quantum dots solar cells). It also includes two chapters demonstrating the use of molecular devices in the areas of solar fuel, water splitting and carbon dioxide reduction. There are further two chapters with interesting examples of solar energy storage related devices, like solar flow battery, solar capacitor and solar energy-thermal energy storage. Three chapters introduce important techniques used to characterize, investigate and evaluate the mechanism of molecular devices. The final chapter discusses the stability of perovskite solar cells. This book is relevant for a wide readership, and is particularly useful for students, researchers and industrial professionals who are working on molecular devices for solar energy utilization.

The book covers the fundamentals, synthesis, processing, material properties, struc...
What Is Amorphous Metal An amorphous metal is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure. But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity and they also display superconductivity at low temperatures. How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Amorphous metal Chapter 2: Bioabsorbable metallic glass Chapter 3: Glass-ceramic-to-metal sea...
Vielen Studienanfängern der Chemie macht vor allem die Physikalische Chemie große Probleme. Dass Chemie nicht nur in Labors stattfi ndet, sondern sich auch mit mathematischen und physikalischen Formulierungen beschäftigt, stellt die Studierenden vor große Herausforderungen. Diesen Schwierigkeiten begegnet das vorliegende Buch, indem es schrittweise und verständlich in alle Teilgebiete der Physikalischen Chemie einführt. Es ist vorlesungsbegleitend für Studierende in den ersten beiden Semestern sowohl im Hauptfach als auch Nebenfach Chemie geeignet.

Im Rahmen dieser Arbeit wurde ein Niedertemperatur Sol-Gel Verfahren zur Beschichtung von Silizium und Edelstahl mit Aluminiumhydroxidfluoriden und reinen Aluminiumfluoriden entwickelt. Diese Schichten wurden auf ihre Verwendbarkeit in der Katalyse, aber auch auf ihre optischen Eigenschaften hin untersucht. Die mit Hilfe eines neuartigen fluorolytischen Sol-Gel Verfahrens und mit der spin und dip coating Technik hergestellten Schichten auf Silizium und Edelstahl wurden mit der Rasterkraftmikroskopie auf ihre morphologische Struktur, mit der Photoelektronenspektroskopie auf ihre chemische Zusammensetzung und mit der Ellipsometrie auf ihre optischen Eigenschaften und die Schichtdicke untersuch...
