Title: DIAMOND/CARBON NANO-MATERIALS HYBRID FILM AND THE FABRICATION METHOD THEREOF
Abstract:
A diamond/carbon nano-material hybrid film is a novel carbon material in which a diamond film is formed at one surface thereof and carbon nano-material is formed at another surface thereof at the atomic level. In a CVD (Chemical Vapor Deposition) diamond synthesis process, layered micro particles are used as matrix and a CVI synthesis technique is employed to provide dual gas chemistry conditions in which a diamond phase is stabilized at an upper surface of a matrix particle layer and a graphite phase is stabilized at a lower surface thereof, thereby fabricating the hybrid film. Also, porous sacrificial matrix particles are used as a matrix, non-deposition portions, at which the diamond or carbon nano-material is not deposited, are formed on the particles during the synthesis process, and the matrix is removed by a capillary-enhanced etching. Accordingly, a diamond/carbon nano-material hybrid film in the form of a free-standing film can be fabricated. This hybrid film has a large surface area and characteristics in which the diamond and the graphite are merged with each other (electrical anisotropy). Also, this method is provided for fabricating a carbon nano-material film well-aligned on a silicon or a metallic or ceramic plate, and for mass producing carbon nano-material in the form of a free-standing film.

Cancer/Viruses/Immunity
Researchers have found that mice with a tumor treated with a viral cancer killer not only have the tumor cured but months later when injected with another tumor have the ability to fight off the tumor themselves - their immune system does so on its own, without any need for more virus cancer tumor killer.
Cancer Vaccine
The procedure used in this study triggered an immune response to cancer cells, which means that it could be used as a cancer vaccine to prevent recurrence.
"We show that if you kill tumor cells directly in the tumor itself, you can get a weak immunity against the tumor, but if you use this virus to kill tumor cells in the lymph nodes, you get a higher immunity against the tumor," Dr. Vile says.
Link
Makes me wonder if that same learning experience by the immune system would be in play with a viricide treatment for any particular virus such as those under development by Nanoviricides who have viricides which can kill viruses. Perhaps when a flu virus of a particular kind is killed by the viricide the immune system is trained, somehow, to fight off any future viral infection of that particular flu bug without the need for more viricide itself - in effect a vaccine is created in the first instance of treatment.
It is thus envisioned that a vaccine could be created in a healthy person by first giving them the viral infection - then treating it with the viricide, killing it off and thereby providing a long lasting immunity - a vaccination, in effect.

Applied Nanotech Inc - ANI - enters the DNA scaffolding self-assembly picture
Biophysicist / Biochemist
Applied Nanotech, Inc., (Austin TX) is looking for a Biophysicist / Biochemist to help start a project in DNA electronics, sensors or similar applications. This could include using DNA scaffolding for self-assembly of devices or systems. Will require building a team, which may include collaborative efforts with university or other organizations or companies. Require writing proposals to help acquire funding support.
Education: PhD or equivalent required. Candidate should demonstrate good verbal and written command of the English language. US citizen or Green Card desired. Please send resumes to Jsoptick@appliednanotech.net
http://www.nano-proprietary.com/ANI/EmploymentANI.asp
The next frontier for information processing may lie at the interface of nanoelectronics and biotechnology.
DNA scaffolding
Special report: Minnesota's Digital Dynasty
An interdisciplinary team led by electrical and computer engineering professor Richard Kiehl is exploring the use of DNA as a programmable scaffolding for the self-assembly of nanoscale electronic components. As a model for fabricating and designing semiconductor devices and circuits, DNA offers two key advantages: size scale and programmability.
Most industry experts believe that within the next 10 to 15 years the ability to scale down conventional technologies will reach its limit. At that point, the operating principles of conventional devices—and the techniques used to fabricate them—will break down. The basic elements of the DNA molecule are at just the right scale, says Kiehl.
Self-assembly uses bio-recognition, a natural process in which one molecule is attracted to and binds with another to form small structures. In the case of DNA, the attraction can be programmed so that the molecules will spontaneously assemble in solution to achieve a desired result.
“It's possible to synthesize small versions of DNA molecules in the laboratory and program in whatever code you want,” says Kiehl. “And because the two strands of DNA have complementary codes that match up, you can design one strand of DNA in a certain way so it will match another strand and assemble a nanoscale structure this way."
The matched segments form a scaffolding on which nanoparticles are affixed at highly selective attachment points. It's an approach that offers the programmability and precision needed for assembling electronic circuitry on the nanoscale.
“We have to make a real paradigm shift,” Kiehl says. “Not only do we have to keep improving performance, but we also must look at the kinds of devices we can make at those scales and how we want to use them to process information."
To that end, the researchers are turning to the human brain for inspiration. They envision devices whose electrical characteristics resemble those of neuron-like electrical waveforms in the brain. Like certain regions of the brain, the devices would process information based on pattern recognition rather than on individual bits of information. It's a more sophisticated level of information processing than can be achieved using conventional computers.
Kiehl predicts there will be a wide range of applications for this technology, including signal processing, communications systems, and computer systems. “The higher end of this [work] will be things that computers can't do very well today because the operations they use are too restrictive. One is the ability to recognize a pattern, such as identifying a letter as being an 'A' or a 'B', or being able to identify a face.
“It won't be just making things faster and faster in the conventional way,” he says. “It will really be opening up new ways to process information in machines."

US Department of Defense grant gives $6M to team of 9 scholars for the study of quantum electronic arrays
The U.S. Department of Defense (DoD) has awarded a team of nine scholars from six universities a grant of $6 million over five years to exploit precise biological assembly techniques for the study of quantum physics in nanoparticle arrays. This research will produce a fundamental understanding of quantum electronic systems that could impact future electronics.
Leading the effort is electrical and computer engineering professor Richard Kiehl of the University of Minnesota, who has wide experience in investigating the potential of novel fabrication techniques, physical structures and architectures for electronics. Kiehl has brought together a multidisciplinary team to develop biological strategies combining DNA, proteins and peptides with chemical synthesis techniques to construct arrays of nanoparticles and to systematically characterize the resulting quantum electronic systems.
Interactions between precisely arranged nanoparticles could lead to exotic quantum physics, as well as to new mechanisms for computing, signal processing and sensing. But even basic studies of such nanoparticle arrays have been hampered by the need to fabricate test structures with extreme control and precision. "By exploiting biology to precisely control size, spacing and composition in the arrays, we will be able to examine electronic, magnetic and optical interactions at much smaller scales than before," said Kiehl. "Our project blends some really fascinating science at the edges of biology, chemistry, materials science and physics. And, I'm excited about the chance to impact how electronic circuits could be engineered in the future."
The team members are UCLA professors Yu Huang (materials science), Kang Wang (electrical engineering) and Todd Yeates (biochemistry); New York University professors Andrew Kent (physics) and Nadrian Seeman (chemistry); University of Texas at Austin professor Allan MacDonald (physics); University of Pennsylvania professor Christopher Murray (chemistry & materials science); and Columbia University professor Colin Nuckolls (chemistry).
Kiehl and Seeman have previously collaborated in the first demonstrations of metallic nanoparticle self-assembly by DNA scaffolding, which will be central to this project. Seeman will exploit DNA nanotechnology to construct 2-D and 3-D scaffolding, while Huang and Yeates will use peptides and proteins to make nanoparticle clusters for assembly onto the scaffolding. Murray and Nuckolls will synthesize metallic and magnetic nanoparticles with organic shells that will self-assemble onto the scaffolding and control the interparticle coupling. Kent, Kiehl and Wang will carry out experiments to characterize the electronic, magnetic and optical properties of the arrays. MacDonald will provide theoretical guidance for the studies and analysis of the experimental results.
The award was made by the Army Research Office (Marc Ulrich, research topic chief) and is one of 36 recently made under the highly competitive DoD Multidisciplinary University Research Initiative (MURI).

Immediately following such appointment, our existing directors resigned effective immediately and terminated their association with us. Accordingly, such creditor may be deemed to control us at the date of the filing of this Report.

Nanotechnology: The Rubber (Finally) Meets the Road
Editorial: Nanotechnology: The Rubber (Finally) Meets the Road
By Paul Nesdore
January/February 2008
Starting from less than front-page applications like non-absorbent clothing (spill red wine on your necktie and it runs right off ), water-free auto windshields (no need for wipers), and airbag sensors, nanotechnology is beginning to fulfill its promises in many areas; and the world of gases is no exception.
An excellent example of the nano-gas connection is the work being done by Applied Nanotech (ANI)*, a company I have been talking with for a number of years about their cutting-edge research and products. My initial conversation, over a year ago, with Dr. Zvi Yaniv, President and COO of ANI, was concerning CO2 and O2 sensors used inside of shipping containers to detect whether a human was concealed. Recently, ANI released information on their ongoing foray into the nanoworld [See News, this issue, page 6] where a further development is taking place with their PhotoScrub® product, a thin film coating on a flexible fiberglass cloth that decomposes organic pollutants at the molecular level in gases and liquids.
The principle of PhotoScrub is based on the catalytic effect of UV light on titanium oxide, TiO2. While this phenomenon was known earlier, by introducing nanophase material as ANI did and creating crystalline columns of TiO2 , the surface area is significantly increased making the catalytic effect much stronger. Because of this, Dr. Yaniv explains, “We will be able to destroy larger organisms.”
The principle is that when UV light impinges on the surface, a disassociation occurs with organic molecules consisting of carbon, hydrogen, and oxygen, resulting in water and carbon dioxide. “Also, it should be noted, that if you can monitor the water and the amount of CO2 created, it becomes a good sensor,” explains Yaniv.
The application to homeland security is important. Among other pathogens, this process can also destroy anthrax. PhotoScrub was tested with actual anthrax (not a surrogate) with excellent results. Tests showed a 99.4% reduction of anthrax spores in less than 20 minutes in a laboratory HVAC setup. Phase II of ANI’s work on PhotoScrub will involve the creation of a unit that can be installed in air ducts of HVAC systems.
Another interesting project that ANI is involved in relates to the ionization process based on electron emission from carbon nanotubes (CNT). “Several years ago we were the first in the world to provide an electron source based on CNT,” relays Yaniv. The history of CNT and ionization goes back about 10 years ago, when as Yaniv explains, advancement was stymied because everyone believed you needed a very high vacuum to produce the emissions. Now ANI has shown, that is not necessary.
Sionex Corporation is partnering with ANI to replace a radioactive ion source in a particular Sionex detection device using electron emission from CNT. Chief Scientist at Sionex, Dr. Erkinjon Nazarov explains, “The project is the result of applying sound fundamental scientific principles to very sound high technology. The result is the stable production of ions, both positive and negative, at atmospheric pressure without the need for a radioactive source, conventional plasma, or corona discharge technologies.”The elimination of the radioactive source is especially important to Homeland Security, reducing the potential proliferation of radioactive materials that could be used in “dirty bombs.”
Future applications are many, perhaps most importantly, detectors. “With the ionized particles, you can attract them, differentiate by mass; you can differentiate by electrical charge—and suddenly you have a beautiful nano-mechanism for sensing,” quotes Yaniv.
So where is nanotechnology headed now? Yaniv looks at the development of nano-science as “enormous.” “It will be in facilitating products, not pure ‘nano-products.’ Yaniv even expands this further. “Is there a product that does not use natural science (physics, chemistry, biology, mathematics) on the market?” Nanotechnology he explains, is just natural science

The history of CNT and ionization goes back about 10 years ago, when as Yaniv explains, advancement was stymied because everyone believed you needed a very high vacuum to produce the emissions. Now ANI has shown, that is not necessary.
Sionex Corporation is partnering with ANI to replace a radioactive ion source in a particular Sionex detection device using electron emission from CNT. Chief Scientist at Sionex, Dr. Erkinjon Nazarov explains, “The project is the result of applying sound fundamental scientific principles to very sound high technology. The result is the stable production of ions, both positive and negative, at atmospheric pressure without the need for a radioactive source, conventional plasma, or corona discharge technologies.”The elimination of the radioactive source is especially important to Homeland Security, reducing the potential proliferation of radioactive materials that could be used in “dirty bombs.”
Future applications are many, perhaps most importantly, detectors. “With the ionized particles, you can attract them, differentiate by mass; you can differentiate by electrical charge—and suddenly you have a beautiful nano-mechanism for sensing,” quotes Yaniv.
So where is nanotechnology headed now? Yaniv looks at the development of nano-science as “enormous.” “It will be in facilitating products, not pure ‘nano-products.’ Yaniv even expands this further. “Is there a product that does not use natural science (physics, chemistry, biology, mathematics) on the market?” Nanotechnology he explains, is just natural science

Welcome
Welcome to my world - weird, wacky and wonderful.
Nano is small and yet will impact our lives more than anything else - an anomaly.
