The Tern Nano-Technology Article

Some time ago I ran across the tern Nano-Technology while searching the net. According to Wikipedia, a brief description is “the control of matter on an atomic and molecular scale”. The Nano-scale is so small it is hard to imagine. To give you some idea a typical penny is about 19,000,000 Nano meters in diameter.

Even as small as it is, Scientists and Engineers have discovered how to manage and manipulate these tiny Nano Element Particles into some very useful and amazing new materials. The other amazing aspect of Nano-Technology is that when elements are reduced to a Nano-scale their physical characteristics change. Solids turn to liquids, stable materials turn combustible, insulators become conductors and opaque substances become transparent. With this knowledge there are and will be some amazing new products introduced into our daily lives.

Although most experts think that the changes brought about by this new science would improve our way of living, some are not so sure. I still continued my quest for new products and would do a search every so often just to see what was out there or what was new. During one of those searches, I ran across a company called Cermet Labs Inc. Their web site was very impressive and the information presented on the site was interesting. They made some claims that I am sure we have all heard before, however since it involved Nano-Technology I read on.

They seemed to have a variety of evidence to back up their statements about what their product would do. I considered the independent lab tests presented and the data on the field testing. It sounded reasonable and I decided to give them a call for more information. As it turns out they were located in a Detroit suburb which was within easy driving distance for me. I make an appointment and met with their CEO and Sales Manager. They made a very detailed presentation about the science behind their product. I understood some of it and some I did not. I guess wasn’t as concerned about how to build a watch, just could I get the correct time. The end result was that I felt it was a reputable company and product; however I still wanted to prove to myself that the claims were true.

The old seeing is believing theory. We went out to the parking lot and injected a 10ml syringe into the oil filler inlet of my car. I discovered later we really did not install it exactly as the instructions called for but it was in the engine now so I was anxious to see the results. Since I hadn’t kept actuate records on my mileage I decided I had better start so I could have a before number to compare to. When I started to keep track of my mileage the car had 205,427 miles on it. I though the car ran well and was getting reasonable mileage. During the first 636 miles the mpg was 21.18 which I though was not bad for a full size 96 Buick Park Avenue.

I was told that during the first 2000 miles of the run in period my mileage could vary. After 1912 miles I was pleased to find that my mpg was now at 25.14. Also it seemed that the car just ran smoother and had reasonably good power. I stopped keeping track for a while and just went about my normal driving. One day it seemed like I was going through a tank of gas quicker that usual. So I decided to check a tank full just to see if anything had changed. My odometer now read 213056 miles and the tank full of gas gave me 24.63 miles per gallon.

According to the EPA rating when the car is new, it should produce 17 and 27 highway. Considering the age and I believe I got this car miles mileage and the best performance is possible. I also believe that, the car’s performance and it is a ceramic ceramic processing laboratory reason. As a side note, I have to laugh when I saw a new car, claiming they will get 27 miles per gallon, $30000 worth of TV advertising. I can fill the tank at $30000 600. It is about 230000 miles.

Carbon Nanotubes For Solar Energy Systems

With the high demand of each priority list of alternative sources of energy, in every state of the engineer working with the hope to save the solar energy can provide the enterprises and individuals more gentle. Solar energy technology, and one of the most spectacular improvement is the introduction of carbon nanotubes (hollow tubes of carbon atoms) is a new solar power system. Carbon Nanotubes are not a recent discovery, they proposed a few years ago, they are their own strength promotion. People realize that they can be used in aircraft construction, lighter and stronger cars, buildings, and even soft ball. However, the fact that the new solar energy, carbon nanotube has launched in the solar system the system stored energy level increased in 100 times more common photovoltaic solar cells.

This finding is credited, for the most part, to a group of MIT chemical engineers. Through their research, they found that by using carbon nanotubes, solar energy can be super concentrated. Their studies showed that the nanotubes could form antennas that are capable of capturing and focusing light energy more effectively thus allowing smaller and more powerful solar arrays.

According to a recent study released in the Journal of Nature Materials by Michael Strano, Associate Professor of Chemical Engineering at MIT and the associated research team, the carbon nanotube antenna, or as they call it the “solar funnel”, might also be useful for other applications that require concentrated light. Among these applications, they specifically made mention of night vision goggles and telescopes.

At the most basic level, the way this process works; solar panels generate electricity by converting photons (packets of light energy) into an electric current. The nanotube boosts the number of photons that can be captured and then transforms this increased level of light into energy that can be funneled into the solar storage cell.

What the MIT team accomplished was the construction a special antenna consisting of fibrous ropes, only 10 micrometers (millionths of a meter) long and 4 micrometers thick. Each fibrous rope contained about 30 million carbon nanotubes. These ropes or micro fibers were made up of two layers of nanotubes with different electrical properties or bandgaps*. The inner layer of the antenna contained nanotubes with a smaller bandgap than the outer layer. This is important because excitons flow from high energy to low energy or, in this specific case, from the outer layer to the inner layer where they can exist in a lower, yet still excited, energy state.

So, what does all of this mean? Well, when light energy strikes the antenna, all of the excitons flow to the center of the fiber where they are concentrated and stored. Better methods of energy storage translate to improved efficiency and improved efficiency means more economical energy resources. As solar power becomes more economical more people will migrate to solar panel installation and solar powered homes and businesses.

The electrons can exist at different energy levels of any material existence.When the excitation energy of the electron is more a photon hits the surface in the material level, to be specific, particular material. The interaction between the excited electrons and holes left called excitons. The band gap of the difference between the electron and hole energy levels of labeled.

Tungsten Carbide Cobalt Nanopowder Insert Recycling:

Tungsten carbide cobalt nanopowder, also known as cemented carbide, is a relatively precious material which is critical to many manufacturing processes. Metal machining process must use tungsten carbide insert tool tip AS, AS hard alloy hardness and wear resistance of a hot ideal shaping, boring, and the metal workpiece. Face Mills the most modern, tool and cutter old lathe used for cutting tools

The only downside of using carbide inserts for such a wide range of machining processes is that the tungsten material used in creating tungsten carbide alloys is both scarce and expensive. With most tungsten reserves in the US and other Western countries exhausted, China supplies over 80% of the tungsten used worldwide. In 2005, the International Tungsten Industry Association estimated that at the current rate of global consumption, all tungsten reserves will be used up within 140 years. Tungsten carbide inserts are typically treated as disposable materials, even though only the cutting edges of the inserts are worn when they’re disposed.

Rather than disposing of inserts, many manufacturers are turning to recycling companies which purchase used tools.

Why Recycle Carbide Inserts?

Financial Benefits
Tungsten carbide is an expensive material, and most recycling companies are willing to pay for used scrap. By turning used inserts over to recycling facilities, manufacturers can recoup at least a portion of their expenses, lowering their overall material costs. Rates for scrap tungsten carbide fluctuate widely, depending on current market values.

Environmental Benefits
Because carbide inserts contain heavy metals, disposing of them in traditional ways can be quite harmful to the environment. Heavy metals may leech into the soil over time, contaminating ground water. By recycling these, these harmful effects can be largely avoided and global tungsten reserves can be preserved for future generations.

How to Find a Tungsten Carbide Insert Recycling Facility

As more manufacturers are becoming aware of the financial and environmental benefits of recycling inserts, more and more carbide scrap recycling facilities are becoming available around the world. Major worldwide toolmaking companies, including Sandvik Coromant, Kennametal and ATI Stellram, offer their own recycling services for customers. While these companies typically offer recycling services to their own customers, they generally offer a reimbursement for the carbide scrap.

Independent tungsten carbide insert and scrap recycling facilities offer an alternative which in many cases may be more financially beneficial to manufacturers. Carbide recycling providers such as Carbide Recycling Company and Machine Tool Recyclers, Inc. tend to offer the highest and most recent going rate for tungsten carbide, so manufacturers may get more in return for their scrap carbide.

Another option is to require manufacturers and their suppliers to help find the best hard alloy recyclers. Some manufacturers may provide internal circulation, or may have some other use of the waste. Turning with carbide blade back to their interests of suppliers, manufacturers can get a credit for future procurement suppliers.
