Achromatic FlatLenses Add More Color to the World of Optics A new, flat lens with the ability to focus light with a higher efficiency within the visible spectrum was reported by a team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) last summer. In order to bend and focus light as it passed, an ultrathin array of nanopillars was used in the lens.

Carbon nanotubes as transistors: Since the discovery of Carbon nanotubes made in 1991 scientists have tried to harness the unique properties of carbon nanotubes.  Some of them are calling it the material of 21. Century because of its extraordinary mechanical, electrical and thermal characteristics. The idea was to create high performance electronics that is faster and consume less power. Of course there was a number of challenges along the way and so far the silicon and gallium arsenide semiconductors outperformed carbon nanotube transistor. Just F.Y.I. the silicon and gallium arsenide semiconductors are used in computer chips. Read more >>>
