The commonly used tool for land mine detection today is the hand-held metal detector. Chemical sensors have been investigated for mine detection. For chemical species having favorable spectral properties, remote sensing can be achieved by fluorescence light detection and ranging LIDAR. Nitroaromatic explosives exhibit strong ultraviolet absorption but low fluorescence, thus direct detection is not practical.

Most of the Zinc Metal Complexes are  fluorescent in nature. But they lose this ability when exposed to chemicals contained in plastic explosives. ( commonly reffered as Quenching). Since each of the complexes react by losing different amounts of their fluorescent ability, they can be used to create sensor arrays that produce a different visual display when exposed to different explosives. This differential que

Got a moment? I ll give u some important information. Have you heard of Bispheol A? Are you aware of its negative effects? If u are, thats great! Or otherwise, i ll detail it.

Bisphenol A is a  chemical used in high volume during the production of polycarbonate plastics and some resins.  Polycarbonate plastics are widely employed in food and drink containers. Resins are also used as protective lining in metal food containers and in water supply pipes. 

The problem comes from the finding that BPA can mimic female sex hormone, estradiol.  Studies reveal that a pregnant mom's exposure to BPA can affect the fertility of the female fetus later in her life.  Experiments on rats reveal breast and prostrate tissue abmormalities in offsprings, which may possibly lead to cancer. 

But these results as such may not be applicable to humans, as the in vivo and animal studies involve higher doses of BPA.  But considering its wide exposure in humans on a daily basis, there is some concern about the health effects of BPA, a report of US National Toxicology Program says.  Govt. o

As it is well known that most of the available antiferromagnets finds application in magnetic heads for reading data from a disc, chromium being an antiferromagnet can be a suitable candidate for these applications.

Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. Its is the basic structural element of all other graphitic materials including graphite, and fullerenes. It is a large aromatic molecule, an extension of a family of flat polycyclic aromatic hydrocarbons.

We can hope that it will soon replace the custom Silicon wafer technology which is always under the shadow of the threatening Moore's Law!
