Nanotechnology for Dummies

Nanomaterials: nanoparticles, nanotubes, quantum dots, fullerense, dendrimers, nanoprorous materials. Nanointermediates: coatins, fabrices, memory and logic chips, optical components Nano-enabling products: finished goods for cars, clothing, airplaines, computers, video, pharmaceuticals, appliances. I found the Lux Research Index reference interesting (LUXI). I read about companies building products like: Zyvex , Mems and Nanotechnology , Nanosys, Altair, NVE (spin state storage MRAM) , FEI (visualization systems), Veeco (data storage and semiconductor), and Accelrys. Hurdles: 1. Cost. The smaller the product being worked on, the more sophisticated and expensive the equipment needed to monitor quality control. 2. Availability. The equipment needed to producing nanomaterials may not be readily available or could be expensive. 3. Regulatory barriers. Evaluations and government approvals are needed to bring products such as a new drug to market, this takes time and time to market means sunk costs. Growth: "Nanotechnology is likely to become a trillion-dollar industry in less than ten years." If this is true the Nanotech indexes reflect the exponential growth explosion. The time required for manufacturing process transform suggests companies are making purchases now and generating capital nanotechnology projects. For example, Toyota should be in the process of covering major sections of their car production lines to use nanomaterials. It may be true that no process modification is required and that raw materials can be substituted for nanomaterials. This is the best scenerio. If nanotechnology is too emerge it could start with a series of new companies that will create radical and disruptive technology. Nanotubes: Researchers found that by adding a few percentage points of vaporized nichkel nanoparticels to the vaporized carbon, they could make as nanotubes as buckyballs. There are three methods for producing nanotubes: 1. High-pressure carbon monoxide deposition, HiPCO. This method involves a heated chamber which carbon monoxide molecules gas and small clusters of iron atoms flow. When the carbon monoxide molecules lands on the iron clusters and the iron acts as a catalyst breaking the molecule into carbon and oxygen. The result is a carbon nanotube and Carbon dioxide. The second method is called chemical-vapor deposition, CVD. In this method a hydrocarbon, such as, methane flows into a heated chamber coated with an iron catalyst. The high temperature causes the carbon and hydrogen break apart. The carbon atoms attach to the catalyst particles forming a nanotube. The third methods uses plasma torch to break apart hydrocarbon producing nanotubes. Nanotube have three topology arrangements: armchair, zigzag, and Chiral. Nanotubes are elastic and strong. Nanotubes conduct heat and cold very well. A nanotube can be either metallic or semiconducting. A nanotube is metallic I the energy level that allows delocalized electrons t flow between a

Before reading this book, I didn't know, nor did I care about nanotechnology. But now, I see all the applications of it in every day life!

It's *amazing* what you can find in the "For Dummies" series... :) I've always enjoyed the Dummies series, especially when it comes to a complex subject where "I don't know what I don't know". A book that can explain the subject in simple terms gives me the mental framework on which to build my learning. This book is a perfect example... Nanotechnology For Dummies by Richard Booker and Earl Boysen. Contents: Part 1 - Getting Small with Nanotechnology: The Hitchhiker's Guide to Nanotechnology; Nano in Your Life; Gathering the Tools of the Trade Part 2 - Building a Better World with Nanomaterials: Nanomaterials Galore; Adding Strength with Composites Part 3 - "Smarter" Computers! Faster Internet! Cheaper Energy!: Building a Better Digital Brain; Routing Information at the Speed of Light; Nano-fying Electronics; Getting Energy and a Cleaner Environment with Nanotech Part 4 - Living Healthier Lives: Diagnosing Personal Health Quickly, Easily, and Pain-Free; The Fantastic Voyage into Medical Applications Part 5 - Investing in Nanotech: Industries Going Small; Countries Investing In a Nano Future; Nanotechnology Goes to School Part 6 - The Parts of Tens: Ten (or so) Nanotech Movers and Shakers; Further Reading on the Web and in Your Library Glossary; Index My prior knowledge of nanotech was pretty much restricted to the sci-fi realm, where machines build themselves and nanotech runs amok. But if asked how it all works, I'd be at a complete loss. In this Dummies title, Booker and Boysen do an excellent job in making the very, very tiny... very understandable. You won't be ready to launch your own nanotech firm or get a degree in nano-medicine, but you'll at least walk away with a better understanding of the subject. While the authors do tend to be wonderfully enthusiastic about the nanotech future, I think that their optimism is somewhat warranted. They show you the edge of the future that we are about to enter, and even after dismissing the hype, there's some intriguing stuff out there. I think I was most fascinated about where the medical field is going with nanotech. Customized delivery systems for medicines that can put the dosage right where it's needed. Nanocells that can attach themselves to cancer cells and then respond to laser stimulation and fry away the cancer. Obviously not next week's cure, but the authors show you it's closer than you might think. If this subject is something you've thought interesting but still don't understand very well, it's well worth getting a copy of Nanotechnology For Dummies. It's an enjoyable read, and you'll come away with many "small" pieces of insight (sorry, bad nano-joke there...)

Sometimes I have to chuckle at the titles contained in the For Dummies series. Nanotechnology is not something that I would normally think of as being of interest to Dummies. I guess I'd best not give examples of subjects I'd think of as being suitable For Dummies. However, that misses the point. The For Dummies series has pioneered a writing style that enables the non-informed reader to get a much better understanding of complex subjects. Nanotechnology is a science that is only about twenty years old. I say 'about' twenty years because it really depends on just what you consider to be the start of the science. Nanotechnology deals with things that are nano in size, say around 1/5000 the size of a red blood cell, about 1/75,000 the diameter of a human hair. At that size, all kinds of strange and wonderful things begin to happen. The technology promises to offer significant improvements in all kinds of areas from energy, health, to computers. I can't really talk about the subject in this short review, it's too big, that's why it takes a whole book to cover. Conclusion: Written in the For Dummies style, this is a book on Nanotechnology that makes it understandable to the average person. I'd consider it mandatory reading for anyone thinking of going into chemistry or physics for a career. My prediction (and the authors) is that this is going to be the hot science subject of the next generation. If I knew a high school student interested in science....
