Foreword

First of all, I would like to congratulate Dr Dibya Prakash Rai for successfully publishing the first edited version of the book entitled “Advanced Materials and Nanosystems: Theory and Experiment”. Nothing surprised me more than the fact that, in comparison to his first release, Dr. Rai prepared the second edited book in such a short period. I know Dr. Rai since when he joined MSc. Physics at Mizoram University in 2007 and he has completed his Ph.D. degree under my supervision in 2013. He was a very hardworking student and later he emerged as a promising researcher. He has a dynamic personality with exceptional leadership qualities which reflect his intellectuality in management by coordinating the authors and the publishers, as a result, he could compile two edited books within a short period.

I'm overjoyed today for two reasons. First, my student has followed the route I've shown him. Second, for his achievements and efforts in a subject that I have always been passionate about (R & D). The title of the book makes me very happy. I wanted to read the full book, but I only had time to skim over each chapter of this edited book due to time constraints. All the chapters and the titles are diverse, very attractive, and cover most of the latest research topics. Though I would love to read every chapter thoroughly once it is published.

The content in this book is concise and thorough, and it covers current advanced materials and nanosystems research. This book takes us on a voyage to a newly found mystical realm that allows us to view atoms with the invention of transmission electron microscopy (TEM). We can now manipulate atoms to obtain useful information thanks to technological advancements. Electronics experts working with integrated circuits competed in a size-minimizing race that progressed from micro to submicron dimensions, bringing them closer and closer to the nanoscale. When scientists eventually get to the point where they can use a single electron as the basis of electronics, the entire concept of electronics will have to be rethought.

This evolution is not limited to electronics, since other disciplines of study such as mechanics, optics, chemistry, and biology have begun to develop their nanoworlds, which we now refer to as microsystems. Nanosystems, on the other hand, do not yet exist. It will take some time for them to emerge from the laboratory. As one must read this book to understand the difficulties and latest technical advancements, in the said topics, which raise the curtain from certain unclear concepts. As a result, we must be conscious of the ongoing difficulties and the stakes.

I'd like to encourage Dr. Rai for publishing a series of volumes of such books every year. I also encourage all the material scientists, engineers, and scholars to read this book and contribute to it.

Once again I would like to congratulate & wish you all the good luck !!!
