Summary

Summary

Water covers more than 70% of the earth's surface and is an essential and major component of all living matter. However, artificially hydrated materials, including hydrophilic materials, are far fewer than one might expect. Currently, these materials are in a state of development for applications in fields such as biomedicine, environmental engineering, and industrial engineering. So what do artificially hydrated materials hold for the future? This book is a great introduction to hydrated materials, presenting academic and practical content that gives a feel of theoretical as well as real-world problems.


Author Notes

Yoshitaka Nakanishi received his Dr. Eng. Degree in tribology from the Graduate School of Mechanical Engineering, Kyushu University, Japan, in 1998. Currently, he is a full professor at the Graduate School of Science and Technology of Kumamoto University, Japan, and vice-chairman of the Kumamoto University Innovative Collaboration Organization, Japan. His current research interests include soft-tribology research and its applications in bioengineering and sustainable technology, Prof. Nakanishi has authored or coauthored 3 books and more than 100 scientific papers as well as organized many conferences and workshops in the field of bioengineering.
