Sol-Gel-Technology in Praxis
Finally! A book on the topic of sol gels that focuses on practical application - designed to fit the needs of hands-on-beginners who want to develop a basic understanding of sol-gel and nano-technology as well as to meet the requirements of advanced formulators seeking a practical guide that will lead them straight into implementable solutions.

With 61 real-life examples drawn from patent literature and accompanying explanations and interpretations, knowledge can be gained quickly and immediately translated into concrete solutions.
Sol-Gel-Technology in Praxis
from Author :
This is not a conventional textbook about colloidal chemistry or the sol-gel process. Many excellent textbooks already have been written about these subjects [1, 2, 5, 23, 60, 137]. This book aims to be a guide for the practical worker and uses an unusual approach. It focuses on practical examples mainly from the patent literature, accompanied by interpretations and explanations. The theoretical basis for these explanations is given in a preface to each example at a minimum level.

When I was a beginner in sol-gel chemistry, now almost 22 years ago, I often felt kind of lost because in publications, textbooks, or the patent literature the authors did not reveal the rationale behind their decisions to use exactly this solvent, that catalyst etc. I always wished for a book for the praxis-orientated beginner which explains all these questions. Now, since I never came across such a book, you hold in your hands my answer to this need.

The interpretations and explanations stem from my own lab experience and are not official statements of the inventors or applicants. The explanations and examples cannot and will not be complete and are not meant to be so. They focus on some practical aspects and try to explain the theoretical background with the help of the examples. Where necessary, all examples have been reworked and adapted for better readability.

Such a book always is a balancing act. A practical guide should be a pragmatic shortcut to a basic understanding and getting quick results. The necessary simplifications should be tolerated by the more experienced reader. Wherever it was possible and appropriate, further literature is recommended for a deeper understanding of the subject. I hope you can feel the joy and excitement I felt during my lab work and during the writing of this book. Even more so, I hope that you feel inspired and can enjoy your own experienceswith sol-gel- and nanotechnology.
