Topological insulators: Persuading light to mix it up with matter

Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been predicted by theorists, ...

The ultimate molecular chess match

For the last two decades, it's been said that carbon nanotubes hold the promise to transform a range of fields, from alternative energy to drug delivery. But making that happen has proved difficult, according to Hicham Fenniri, ...

Large wave-vector phonon modes in silicon nanomembranes

(Phys.org) —Modified large wave-vector phonons in semiconductor membranes via hard X-ray thermal diffuse scattering (TDS) were observed that provide new insight into the fundamental thermal and electronic properties of ...

Jagged graphene edges can slice into cell membranes

(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt ...

Optics: Statistics light the way

Millions of years of evolution have molded our eyes into highly sensitive optical detectors, surpassing even many man-made devices. Now, Leonid Krivitsky and his co-workers at the A*STAR Data Storage Institute and the A*STAR ...
