A glimpse inside the atom

An electron microscope can't just snap a photo like a mobile phone camera can. The ability of an electron microscope to image a structure – and how successful this imaging will be – depends on how well you understand ...

A 'bridge' of carbon between nerve tissues

A new material made of carbon nanotubes supports the growth of nerve fibers, bridging segregated neural explants and providing a functional re-connection. The study, which was coordinated by SISSA in Trieste, also observed ...

Tiny DNA 'legs' walk with record fuel efficiency

(Phys.org)—For the first time, researchers have demonstrated a DNA nanomotor that can "walk" along a track with sustainable motion. The nanomotor also has the highest fuel efficiency for any type of walking nanomotor, or ...

Scientists grow atomically thin transistors and circuits

In an advance that helps pave the way for next-generation electronics and computing technologies—and possibly paper-thin gadgets —scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley ...

Hybrid nanogenerator harvests hard-to-reach ocean energy

(Phys.org)—Energy from the ocean, or "blue energy," is arguably the most underexploited power source, according to researchers in a new study. Although the oceans contain enough energy to meet all of the world's energy ...

Engineered 'sand' may help cool electronic devices

Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry ...

'Golden' silver nanoparticle looks and behaves like gold

(Phys.org)—In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and ...

Electrical circuit made of gel can repair itself

(Phys.org)—Scientists have fabricated a flexible electrical circuit that, when cut into two pieces, can repair itself and fully restore its original conductivity. The circuit is made of a new gel that possesses a combination ...

Researchers uncover new light harvesting potentials

Researchers for the first time have found a quantum-confined bandgap narrowing mechanism where UV absorption of the graphene quantum dots and TiO2 nanoparticles can easily be extended into the visible light range.
