NANO The Essentials

December 9, 2008

In his insightful memoirs, War As I Knew It, General George S. Patton, one of history’s most charismatic, famous and successful generals, gifted us an priceless gem of his human resource management wisdom: “Never tell people how to do things. Tell them what to do and they will surprise you with their ingenuity”.

 

Ever since I read this illuminating book more than thirty years ago, I have followed this adage with great success in my multifarious avatars as a Human Resource Manager, a Project Manager, a Design Engineer, a Teacher and a Mentor.

 

A few days ago, a young lady, Prachi A Deshmukh, a fresh engineering graduate, joined our department as a research fellow; and I gave her a book from my bookcase, told her to review it and email me her book review by the end of the day. [As per my style, I just curtly told her what to do, not how to do it].

 

When I opened my email early next morning, the book review was there, waiting for me, and yes, Prachi Deshmukh had indeed surprised me with her ingenuity. I am truly proud of my young colleague and mentee.

 

A delight to read, written in a refreshingly youthful vibrant style, breathtaking in its simplicity, I liked the book review so much that I am placing it below as it is, with minimal editing, for you to read. We look forward to your comments and feedback; do tell us if you enjoyed reading the review, and the book.

[Reviewed by Prachi A. Deshmukh]

 

At the root of every invention, there is a seed of a thought which was unbelievable at that time. Yesterday’s dream is today’s truth; yesterday’s imagination is today’s reality. Let us take an example of ATM. Today we use ATM as if its ‘Any Time Money’ machine; but if we had told about this to somebody in the last century, he might had thought that we have gone mad! The same thing happened in December 1959, when Richard Feynman gave an after dinner speech at the annual meeting of the ‘American Physical Society’. He took the audience in the amazing world of his imagination. He was telling about the future where everything will be so small that there will be machines smaller than the tip of a needle. People were laughing, enjoying his ideas but no one knew the real meaning of his words-“There is plenty of room at the bottom.” Feynman is now credited for his great foresight which made him the first prophet of nanotechnology.

 

21st century is the era of great revolution in technology. Information Technology, Bio Technology and Nano Technology are some of the great windows which have tremendous capabilities to change the world around us. Especially Nanotechnology is a promising field in the near future which will provide us with many breakthroughs in a wide range of applications. It has been predicted that by the year 2015 the market share of nanotechnology and nanoscience will be worth 350 billion dollars. This calls for new investments in human resource development. These people must have strong foundation to build strong building. For those who are interested in this new technology, the book ‘Nano: The Essentials’ will prove to be a true guide.

 

The author of this book- Prof. T. Pradeep is with the IIT – Madras [Chennai]. Being a professor, he has structured this book so nicely that the reader gets his concepts clear right from the beginning. Starting from the preface we get more and more interest in this amazing world of nanotechnology and nanoscience.

 

The content of the book is well organized into five parts. In the first introductory part the author takes us in the world of nanotechnology with its relation with the nature. This part is enriched with the details of the technological inventions of 20th and 21st century.

 

In second part, we move towards the experimental methods. The author introduces us with the different types of microscopies . The neat diagrams, graphs and pictures in this part make it easier to understand the different experimental methods.

 

In the third part, we enter into the world of fullerenes, carbon nanotubes, gas phase clusters, nanoshells etc. In this section also, author addresses us with his simple language. There are sufficient diagrams and graphs to understand the concept properly.

 

In fourth part we become familiar with nanobiology, nanosensors,  nanomedicines , nanotribiology and molecular nanomachines.

 

Whenever some new technology comes into picture it’s the duty of every conscientious technologist to study the societal implications of it. In the fifth part we go through the relationship between nanotechnology and the society.

 

The most appreciable thing in this book is I think the ‘History of nanoscience and nanotechnology’ which tells us about all the important events in the development of Nanotechnology. Hats off to the author for this effort. The glossary of nanoterms at the end of this book summarizes all the important terms used throughout the book.

 

The author has given the references and additional related reading books at the end of every chapter for the keen readers to know more about the things.

 

In simple words, the book ‘Nano: The Essentials’ is really essential for those who are keen to know about nanotechnology and nanoscience . With his simple language the author has maintained the flow throughout the book. There are plenty of diagrams, graphs, tables and pictures which make the study more meaningful. If you are really serious about nanotechnology, then I will insist you to have a copy of this book. It’s easier for understanding if you have enough base of science and technology. I recommend this book to students, engineers, teachers and technologists who are willing to enter in this amazing world of nanotechnology and nanoscience.

EMC for Product Designers – Book Review

December 9, 2008

A Comprehensive Reference Book for IT, Electronic, Telecom and Electrical Engineering and Design Professionals

 

 

Title: EMC for Product Designers

Author: Tim Williams

Elsevier [Fourth Edition, 2007] 498 pages

ISBN – 13: 978-0-75-068170-4

ISBN – 10: 0-750-68170-5

 

 

 

Most of us consider a number of factors, exoteric and esoteric, while designing [or selecting] our homes and in the configuration of the numerous modern technological devices and domestic appliances, most of them electrical and electronic, therein.

 

Recently I saw a programme on TV where a Vastu Shastra expert was advising viewers not only regarding the various aspects of designing and building living environments that are in harmony with the physical and metaphysical forces but also specifying optimal locations and layouts for various electrical and electronic appliances and devices in both residential homes and workplaces.

 

I listened with intriguing interest as he gave precise directions and specified exact locations for positioning of Televisions, Computers, Communication Devices, Microwave Ovens, Music systems and other appliances, and fascinated by the congruence between principles and aspects of Vastu and Electromagnetic Compatibility [EMC] and wondered whether the expert in reality was actually an EMC Design Engineer in addition to being a Vastu Shastra Specialist.

 

When you design or select or configure your house or office I am sure you consider various aesthetic, architectural, financial, utilitarian, geographical, interior and exterior design and other practical aspects, maybe even incorporate the principles of Vastu Shastra and Feng Shui, but do you give even a fleeting thought to EMC?

 

In today’s world with the increasing use of electrical, communication, electronic and information technologies we are under continual exposure to Electromagnetic Field [ EMFs ], both inside and outside our homes, in our workplaces and even in the open wherever we go, radiating from radiating from electricity power lines, household wiring, microwave ovens, computers, monitors, televisions, communication devices, cellular phones, electrical, electronic and IT appliances.

 

“Electro-pollution” is an increasingly serious form of Environment Pollution and merits serious consideration, as much as, if not more than, other well-known forms of pollution.

 

Electro-pollution seems to be omnipresent. Apart from hazards to our health, Electromagnetic Interference [EMI] is detrimental to the proper functioning of most electrical, electronic, IT, ITES, communication and technology-based systems and may cause malfunctions and even potentially disastrous and fatal accidents.

 

The book being reviewed – EMC for Product Designers by Tim Williams – is one of the most comprehensive reference books I have read on the subject of the Design Management aspects of Electromagnetic Interference and Electromagnetic Compatibility [EMI / EMC].

 

The book comprises sixteen chapters arranged in three parts [Legislation and Standards, Testing and Design] the author lucidly covers most micro and macro aspects of EMC Management in meticulous detail.

 

The logical sequence of topics, clear diagrams, tables and illustrations facilitate easy understanding of this complicated subject.

 

The Design Checklist, interesting Case Studies and useful mathematical formulae in the appendices and the extensive bibliography add value to this reference book.

 

Whilst the earlier chapters provide an excellent understanding of the EMC Standards and the basic theoretical principles of EMI / EMC, the “meat” of the book lies in the chapters on Systems EMC and EMC Management which encapsulate all relevant facets of EMC in a holistic manner.

 

I wish the author had included a detailed chapter on Electromagnetic Health Hazards and mitigation techniques. This most vital topic concerning all of us humans seems to have not been accorded the due importance it deserves and I hope the author presents a more holistic and systemic view of EMC and includes a comprehensive chapter on pertinent aspects of Bio-electromagnetics, Thermal and Athermal EMR Hazards and their mitigation in the next edition.

 

I commend this book – it is an excellent reference book for Electrical, Electronic, Telecommunication and IT Engineers and Managers, Designers, Students, practising professionals in the field and, with the increasing awareness and compliance requirements of EMC Standards worldwide, this book will prove a valuable addition to the shelnves of engineering and technical libraries.
