Graphene Holds Promise For Spintronics
Graphene is a nanomaterial
combining very simple atomic
structure with intriguingly
complex and largely
unexplored physics. Since
its first isolation about
four years ago researchers

Hearing The Sound Of Quantum Drums
Forty years ago,
mathematician Mark Kac asked
the theoretical question,
"Can one hear the shape of a
drum?" If drums of different
shapes always produce their
own unique sound spectrum,

Optical Atomic Clock: A Long Look At The Captured Atoms
February 8, 2008 — Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. As its ... > full story -
'Hot' Oxygen Atoms On Titanium Dioxide Motivated By More Than Just Temperature
February 8, 2008 — Catalysts typically break down an oxygen molecule into two identical atoms that behave the same. But on a titanium oxide catalyst, the two atoms of a split oxygen molecule act differently: one fills ... > full story -
Particle Accelerator: Signals Sent Racing Ahead At Light Speed To Keep Particles Colliding
February 7, 2008 — Imagine trying to catch up to something moving close to the speed of light - the fastest anything can move -- and sending ahead information in time to make mid-path flight corrections. Impossible? ... > full story -
Helium-8 Study Gives Insight Into Nuclear Theory, Neutron Stars
February 6, 2008 — The most neutron-rich matter that can be made on Earth--the nucleus of the helium-8 atom--has been created, trapped and characterized by researchers. This new measurement gives rise to several ... > full story -
New Process Makes Nanofibers In Complex Shapes And Unlimited Lengths
February 6, 2008 — The continuous fabrication of complex, 3-D nanoscale structures and the ability to grow individual nanowires of unlimited length are now possible with a new process. Based on the rapid evaporation of ... > full story -
Particle Accelerator May Reveal Shape Of Alternate Dimensions
February 4, 2008 — When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions. String theory, which describes ... > full story -
Some Solids Mimic Liquids On Nanoscale
February 4, 2008 — Physicists and astronomers have shown how some solids behave like liquids on the nanoscale. This is a major step forward in discovering how to measure polymer substances using nanoscale technology. ... > full story -
Scientists Propose Test Of String Theory Based On Neutral Hydrogen Absorption
February 1, 2008 — Ancient light absorbed by neutral hydrogen atoms could be used to test certain predictions of string theory, say cosmologists. Making the measurements, however, would require a gigantic array of ... > full story -
Tiny Avalanche Photodiode Detects Single UV Photons
February 1, 2008 — Researchers have demonstrated visible-blind avalanche photodiodes capable of detecting single photons in the ultraviolet region (360-200 nm). This is a world's first for demonstrating ... > full story -
Magnetism Loses Under Pressure
January 30, 2008 — Scientists discovered that the magnetic strength of magnetite -- the most abundant magnetic mineral on Earth -- declines drastically when put under pressure. Researchers have found that when ... > full story
