Nanotechnology For Dummies

If You're Serious About Learning Nanotechnology...Look Elsewhere 2010-06-13

Reviewer: Casey Kemp

If you want a 'fluff laden' book, then this one is for you; however, if you want to know more than just how to spell 'nanotechnology' you may want to look elsewhere. Remember, it is for Dummies.

I bought this book from amazon.com at very affordable price.
I got the book within a week. Book was in a very good shape like new.
I think it is wise to shop at Amazon.com

Nanomaterials, Nanointermediates, Nano-enabled products 2006-12-03

Reviewer: Golden Lion

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 atoms throughout the nanotube is right above the energy level used by electrons attached. A nanotube is semiconducting if the energy level of the conduction band is high enough sou that there is an energy gap between it and the valence band. Nanotubes will provide more efficient energy transmission and faster and more power computers. Nanotube tensile strength (GPa)=200, Young's modulus(GPa)=1000, and density=2.

Nanowire: Researchers have demonstrated using nanowires to create memory devices and transistors. A nanowire crosslatched arrangement will be able to store 40 gigabits per square centimeter.

Polymer composites: "Scientist at University of Urbana-Champaign have demonstrated a unique self-healing composite. It involves dispersing microcapsules and catalyst within the composite. When the catalyst comes in contact with the healing agent inside the microcapsule, the healing agent polymerizes and hardens." Heals microcracks resulting from temperature changes or pressures of mechnical loading.

NanoTransistor: A transistor is the switch that says whether a bit is 0 or 1. Think of a water dam. In the off position no water is flowing through and on the water is flowing, electrons are flowing freely. The smaller the transistor, the smaller your electron gate-which means faster switching between on and off, resulting in a faster overall processor.

Photoelectrochemical hydrogen extraction: A photoelectrochemical device is a 30 nm layer of nanoparticles placed on a conductive glass. The nanoparticles are composed of semi-conducting oxides. The conducting glass is connected to an electrode. The space between electrode and nanoparticle film and conductive glass is filled with water. Light strikes the layer of nanoparticles knocking the electron's loose. Those electrons move through the conducting glass layer to the metal electrode putting a negative charge in it. You have a layer of nanoparticles that electrons are rushing out and a nearby metal electrode that electrons are rushing in. Hydrogen is emitted. (Hydrogen Solar Ltd)
