BrandAuthen is a covert product authentication technology used to protect brands against counterfeits. BrandAuthen enhances your brand security by providing a covert authentication mechanism which is all but impossible to duplicate, but very easy to authenticate.
Transmission electron microscopy image of BrandAuthen
(1 yard or 1 meter =1,000,000,000 nm)BrandAuthen particles are about 10,000 times thinner than the human hair. This small size makes them to be undetectable to the naked eye, so they can be printed in completely transparent layers over other graphics. By contrast, older flourescent particles are visible to the naked eye due to their large particle size, some 1,000 times larger than BrandAuthen. To achieve the small particle size and advanced functionality of BrandAuthen, a counterfeiter would need a large group of specialized PhD’s. Because globally there are only a handful of individuals with the requisite expertise, counterfeiters are unable to conduct this type of reverse engineering. Thus, BrandAuthen provides a very high level of security.

Mirage effect helps researchers hide objects
Ali Aliev and coworkers at The University of Texas at Dallas, US, have demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible. This invisibility for light oblique to the nanotube sheets is caused by the mirage effect, in which a thermally generated refractive index gradient bends light away from a hidden object.

Nano: The Next Dimension
"Nanosciences and nanotechnologies represent a formidable challenge for the research community and industry.
World-class infrastructure, new fundamental knowledge, novel equipment for characterization and manufacturing, multi-disciplinary education and training for innovative and creative engineering, and a responsible attitude to societal demands are required.
This documentary film, made available by the European Commission, provides a glimpse of some of the many activities that are being carried out in Europe in these fast-grozing fields of research and technological development."

Japan nano-tech team creates palladium-like alloy: report
The alloy has similar properties to palladium, which is used in cars' emission-reducing catalytic converters as well as in computers, mobile phones, flatscreen TVs and dentistry instruments. Like other white metals, such as silver and platinum, palladium is expensive, with its deposits largely limited to South Africa and Russia...' http://www.physorg.com/news/2010-12-japan-nano-tech-team-palladium-like-alloy...
