According to the researchers, the chip would theoretically have several hundred times more storage than
conventional microchips of the same size. Five Terabits could fit on, coincidentally, a nickel. If nanodot
memory chips eventually succeed, the entire contents of the Library of Congress could fit onto a pocket
full of "change."

Nanotechnologists' new plastic can see in the dark
"Our calculations show that, with further improvements in efficiency, combining infrared and
visible photovoltaics could allow up to 30 per cent of the sun's radiant energy to be harnessed,
compared to six per cent in today's best plastic solar cells."

Nano paint could boost antiterrorism, rescue efforts
The material has the potential to enhance infrared images tenfold by coating lenses with a film a
10th of a millimetre thick and powering the material with a laser.

IBN Pioneers Breakthrough Method in Nanoparticle Synthesis
The Institute of Bioengineering and Nanotechnology (IBN) has developed a novel method
to simultaneously control the size and morphology of nanoparticles, which can be used in
pharmaceutical synthesis and novel biomedical applications.
Research Scientist Dr. Yu Han and IBN Executive Director Prof. Jackie Y. Ying have
developed a fluorocarbon-mediated-synthesis technique that produces nanometer-sized
particles of between 50 and 300 nm with tunable pore sizes in the range of 5-30 nm.

"We have shown that solar cells based on quantum dots theoretically could convert more than
65 percent of the sun's energy into electricity, approximately doubling the efficiency of solar cells,"
Nozik said. The best cells today convert about 33 percent of the sun's energy into electricity.
