Significant progress made in inverse photoconductance

Valencia University (UV) researchers have modified the photoconductance of nanoparticles of tungsten oxide (WO3) in a controlled manner. This has potential applications in photonics and optomechanics. The results have been ...

Gem-like nanoparticles of precious metals shine as catalysts

A Northwestern University research team has developed a new method for making highly desirable catalysts from metal nanoparticles that could lead to better fuel cells, among other applications. The researchers also discovered ...

Chameleon inspires 'smart skin' that changes color in the sun

A chameleon can alter the color of its skin so it either blends into the background to hide or stands out to defend its territory and attract a mate. The chameleon makes this trick look easy, using photonic crystals in its ...

Conductivity at the edges of graphene bilayers

The conductivity of dual layers of graphene greatly depends on the states of carbon atoms at their edges; a property which could have important implications for information transmissions on quantum scales.

Time-saving simulation of peeling graphene sheets

Control of atomic-scale friction and adhesion is critical for effective manipulation of the motion of nano- or micro-meter scale objects at interfaces. For example, in nanotechnology controlling adhesion during the peeling ...

Optical vacuum cleaner can manipulate nanoparticles

Scientists at Tomsk Polytechnic University jointly with Russian and international colleagues developed the concept for constructing an "optical vacuum cleaner." Due to its optical properties, it can trap nanoparticles from ...

Metal-organic framework nanoribbons

The nanostructure of metal-organic frameworks (MOFs) plays an important role in various applications since different nanostructures usually exhibit different properties and functions. In this work, the authors reported the ...

Creating new opportunities from nanoscale materials

A hundred years ago, "2d" meant a two-penny, or 1-inch, nail. Today, "2-D" encompasses a broad range of atomically thin flat materials, many with exotic properties not found in the bulk equivalents of the same materials, ...
