TechAndComputer (Nov. 27, 2012) A seamless graphene/nanotube hybrid created at Rice University may be the best electrode interface material possible for many energy storage and electronics applications.
Led by Rice chemist James Tour, researchers have successfully grown forests of carbon nanotubes that rise quickly from sheets of graphene to astounding lengths of up to 120 microns, according to a paper...

TechAndComputer (Oct. 8, 2012) Businesses and consumers may soon have a simple, cheaper way to store large amounts of digital data.
Case Western Reserve University researchers have developed technology aimed at making an optical disc that holds 1 to 2 terabytes of data -- the equivalent of 1,000 to 2,000 copies of Encyclopedia Britannica. The entire print collection of the Library of Congress could fit on five to 10 discs.
The discs would provide small- and medium-sized...

TechAndComputer (Oct. 1, 2012) September 28, for the first time ever, SES, the Luxembourg-based satellite operator, has allowed an Ariane 5 rocket to transport a TV satellite into space, which is made by Astrium and runs entirely on latest generation software. Every single one of the programs used to operate the satellite was written in the new satellite language SPELL. The acronym stands for "Satellite...

TechAndComputer (Sep. 25, 2012) The current trend to digitize everything is not lost on fine art. Documenting, distributing, conserving, storing and restoring paintings require that digital copies be made. The Google Art Project, which brings art from galleries around the world to online audiences, was launched in early 2011 for precisely these reasons. Google's project has been a complex undertaking, however, carried out under carefully controlled settings using state-of-the-art...
