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.

Use Up Raw Materials First In The US

In the United States we have abundant raw materials and natural resources. Many in the United States of America the mines have been closed, the raw materials we too much from other countries, must arrive here at a very high cost. Many of the raw materials we get from other nations are not as good as the raw materials we have here and that is a real problem.

Likewise in the future many of the raw materials we have in the United States we will not need because the likelihood of us making things out of steel and copper are not too probable. We will have Nano diamond powder tubes may have carbon, fiber optics, special composites and super alloys made from exotic metals or that have be re-engineered at the molecular level. Because this is the obvious future, we should use our own raw materials in the United States first.

Many economists and the old way of thinking believe we should use raw materials from other nations first and then when they ran out we would be last with our own raw materials and not have anything to worry about. However technology and the rapid advances in research and development has shown us that in the future we will not need these raw materials anyway.

Our goal should be to use our own raw materials in the United States first and work on innovation, research and development was prospected materials in the future to make things better, with their own raw materials. As long as we can use our own in a responsible and environmentally friendly way of raw material that is meaningful to the ground here for the first time to use our materials to use their own. Please consider take this into consideration in 2006.

Carbon Nanotubes Are Invisible Barricade

You know that carbon nanotubes are very small and very strong, they do a lot of things almost perfect material. The increase in material science, this technique will allow us to build lighter vehicles that get better gas mileage, the stronger the aircraft structure, more powerful, and all other all.Indeed, our intranet style think tank often discusses Carbon Nanotubes, graphene coatings, and other high-tech materials which are just now hitting the scene. Of course, we are most interested in commercial applications.

Now then, let me tell you about a concept I recently came up with; carbon nanotube road blocks to be used in areas like Afghanistan where we are fighting insurgents. We can build a system which raises and lowers these road blocks so our convoys can get through. If we find insurgents are moving in the middle of the night, perhaps to plant roadside bombs merely leave the roadblocks down and in place. Since we can make these carbon Nanotubes very strong, very thin, you wouldn’t be able to see them as you approached.

Instead, you could have many strings of carbon nano tubes, perhaps only 100 Nanotubes thick, not much wider than a very thin fishing line across the road. The only difference is these fishing lines, would be 250 times stronger than steel. And if you thought the insurgents would most likely be coming on a motorcycle, you could put them across the road at about neck height. These carbon nanotubes would not only stop vehicles, they would cut right through them and make them unable to drive. Indeed they would cut through flesh like it wasn’t even there, shesh – I can hear the angry insurgents now; “that’s not fair!”

Remember, in this case we are dealing with terrorists, members of Al Qaeda, insurgents, or the Taliban and which are hellbent on killing US and NATO troops. And they love to plant their roadside bombs late at night. Of course, if we set up these carbon nano-tube roadblocks, they certainly wouldn’t be able to do that now would they? Please consider all this.Lance Winslow is the Founder of the Online Think Tank, a diverse group of achievers, experts, innovators, entrepreneurs, thinkers, futurists, academics, dreamers, leaders, and general all around brilliant minds.

Nano Element Particles on Dispersing in ODS Steel

From the irradiation resistance and high-temperature strength, oxide dispersion strengthened (ODS) ferritic steels are candidate materials for advanced and fusion reactors. For the development of advanced steels the key issue is to homogenize nano-particles into matrix. Recent studies have indicated that Ti addition can homogenize Y-Ti complex particles into ferrite matrix, but the reason of the effect of additional elements has not been clarified. In this model study, we focus on the effect of additional elements, such as IV and V families and other oxide formers, which can control potentially the distribution of the oxide particles.

The materials used in this study were based on Fe-9Cr-Y2O3 alloys which were mechanical alloyed (MA) from the powder of Fe, Cr and Y2O3, which was added systematically with the element of Ti, Zr, Ta, V, Nb, Hf, Al, Si and others. Usually ODS fabrication process is required for hot extrusion, but we annealed up to 1150 C for simplify the microstructure. To evaluate the distribution of ODS Nano Element Particles ; we used TEM equipped with EDS after electro-polishing or FIB techniques.

(1) In the case of Si or Al addition, oxides were disappeared after MA process, which means Y2O3 and other elements should be in solution at non-equilibrium condition. Two types of oxides of Y2O3 and Al2O3 or SiO2 developed after the annealing at 850 C,b> developed after the annealing at 850 C, but only complex oxides were developed after the annealing at 1150 C. This result suggests that the oxide formation is independent process for Y and Si or Al. (2) In the case of Ti addition, oxides also were disappeared after MA process, but developed after annealing at 1150 C. This means that Ti can stabilize complex oxides of Y and Ti, and enhance the fine distribution of the oxides comparing with simple Fe-9Cr-Y2O3 alloy.

Antimony Doped Tin Oxide market demand

 

With the rapid economic development, electronics, chemicals, textiles, machine room, static electricity problems in packaging and other industries have attracted wide attention. Conductive filler can eliminate the matrix materials, such as plastics, coatings, chemical fiber, rubber, ceramic tile is the main method of static electricity, by on the principle of conductive filler in the insulating substrate forming a conductive network charge to reach the matrix release purposes. Commonly used include permanently conductive filler metal powder, carbon, oxides, and so on. To reduce costs or improve existing in conductive fillers fillers chroma can be chemically heterogeneous nucleation theory in some white powder coating formation of Antimony Doped Tin Oxide composite conductive powder. Due to the conductive path formed in the substrate is a prerequisite for eliminating static electricity, so using high aspect ratio materials, such as conductive carbon nanotubes, carbon fiber, conductive metal fibers (stainless, nickel fiber, etc), needle-shaped titanium dioxide coated ATO, can reduce the amount of conductive material, thereby reducing production costs.

Antimony Doped Tin Oxide coating should first consider its dispersion in the paint, though Antimony Doped Tin Oxide compared to have better dispersion of metal powders, but due to its high surface energy of nanometer powder made prevailing in its powder agglomeration, increase of the dispersion degree of difficulty. This years of slow progress in the application of nano-ATO conductive powder are the main reasons. Of nanometer ATO powder by dispersing and anti-static application data show that, with the decrease of slurry particle size of nano-ATO particles in, that are required to achieve the same anti-static effect of nanometer ATO powder dosage reduced, reduce operating costs, while mechanical and optical properties of materials have also been improved.

Its good insulating properties, is widely used in the coatings, chemical fibre, polymer film and other fields. In addition as a conductive materials, dispersion, activity, thermoplastic-resistance, abrasion resistance, security with other conductive material (such as graphite, surfactants, such as metal powders), incomparable advantages. Is used in optoelectronic display, transparent electrode, solar cell and LCD, catalytic, and so on.

Antimony Doped Tin Oxide powders and conductive material offers significant advantages over traditional, in transparent, conductive, anti-static, infrared blocking and other fields, has broad application prospects. But in electro-optical mechanism of Antimony Doped Tin Oxide powders, Nano-ATO powder application and secondary development of nanometer ATO powders and other aspects to be further studied.
