Microsoft buy Skype for $8.5bn
in their latest acquisition:
Why? when
Skype has changed hands so many times, never made money, and comes
with substantial debt! It's
worked before. Microsoft's hardware/software integrated devices,
Xbox and Kinect, are enjoying strong revenue growth and great margins:
$1.9bn revenue last quarter, 50% more than last year, with 10% operating
profit.
They already own Nokia making them
one of the worlds major players in smartphone communications. It
seems that microsoft's diversification is set to corner yet another
market.

Graphene
THE FUTURE of electronics and many other
Graphene,
a single-atom-thick honeycomb lattice of carbon atoms, can transport
electrons more quickly than other semiconductors, a quality called
electron mobility.
Scientists
at the University of Pittsburgh have created the first single-electron
transistor, made of oxide-based materials (Graphene) and artificial
atoms.
These researchers
say their SketchSET (sketch-based single-electron transistor) could
be the first step to the next generation of quantum computers, advanced
electronic materials, and more powerful solid-state computer memory.
The experimental
transistor's central element is a 1.5-nanometer wide island, that
only needs 1 or 2 electrons to operate. The miniscule size of the
transistors could be used to manufacture denser memory modules,
for more storage capability.
More importantly,
the transistor's ability to control electrons without an external
current could lead to data storage without the need for batteries.
When this technology hits the real world, the result would have
a dramatic impact on all silicon based electronics including much
smaller and more powerful computers and vast data storage capabilities.
But this is just the tip of the iceburg, the potential is limitless
and will have as much effect on electronics as the silicon chip
had way back in the "dark ages"
After you
have seen this you will all want one !
Graphene
news and resources
One more use for this
exciting mew material. Graphene can be used in many industries -
from electronics to water purifiers, from displays to super-capacitors
and car batteries. We offer daily news and resource about this exciting
new technology.
NRL researchers show that graphene's valley degree of freedom can
be polarized via scattering off a line defect
Researchers from the
Naval Research Laboratory (NRL) shown that the valley degree of
freedom in graphene can be polarized through scattering off a line
defect. This makes valley-based electronics (valleytronics) one
step closer to reality. Valleytronics may present a middle-ground
between spintronics and electronics using the valley degree of freedom
(which exists in certain crystals, including graphene).
The NRL research shows
that an extended line defect in graphene acts as a natural valley
filter. "As the structure is already available, we are hopeful
that valley-polarized currents could be generated in the near future"
said Dr. Daniel Gunlycke who made the discovery together with Dr.
Carter White. Both work in NRL's Chemistry Division.

Graphene paper - a new strong
and flexible material
Researhcers from the
University of Technology in Sydney, Australia, developed a new material
called Graphene paper (GP), made from Graphite which is lighter,
stronger, harder and more flexible than steel. It's also eco-friendly
and recyclable. The new material is thinner than paper and ten times
stronger than steel. The researchers say that the new material can
be used in the automotive and aviation industries - to create lighter
planes and cars which will be require less fuel, and yet be even
more safe.
The new GP is made
using raw graphite which is milled and purified using a chemical
bath. This allows it to be pressed into thin sheets.
Watch
out for Graphene IT IS the future !
