Lab clocks 'hot' electrons: Plasmon-generated electrons timed moving from nanorods to graphene

more »

Scientists time "hot" electrons as they transfer from excited plasmons in gold nanorods to graphene. Plasmonic nanoparticles are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly as well understood. Scientists are working on that, too. They suggest that the extraction of electrons generated by surface plasmons in metal nanoparticles may be optimized.

Super-strong graphene oxide: In situ bandgap tuning of graphene oxide achieved by electrochemical bias

more »

The ability to modulate the physical properties of graphene oxide within electronic components could have numerous applications in technology. Super-strong graphene oxide (GO) sheets are useful for ultrathin, flexible nano-electronic devices, and display unique properties including photoluminescence and room temperature ferromagnetism.

Imaging ferroelectric domains

more »

(Phys.org) —When thin films of ferroelectric materials are grown on single-crystal substrates, they can develop regions of aligned polarization—called "domains"—that often adopt complex patterns. Manipulation of ferroelectric domains can lead to advances in a number of technologies. However, in order to manipulate the domains, it is important to study their natural development. Previous studies have shown that interfacial strain and electrical boundary conditions play a large role. Accurate measurements of the local polarization can help science learn more. By changing the properties of the substrate and the interfaces of the ferroelectric materials, one can control the size and shape of the domains and thus influence the behavior of the material.

Galaxies, Stars and Nebulae series A breathtaking outer space picture showing a spectacular three-colour composite mosaic image of the Eagle Nebula (Messier 16, or NGC 6611). It's based on images obtained with the Wide-Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory.

At the centre, the so-called “Pillars of Creation” can be seen and this wide-field image shows not only the central pillars, but also several others in the same star-forming region, as well as a huge number of stars in front of, in, or behind the Eagle Nebula.

The cluster of bright stars to the upper right is NGC 6611, home to the massive and hot stars that illuminate the pillars. The “Spire” - another large pillar - is in the middle left of the image.

Light Pillars from a Little Planet

more »

Eerie pillars of light ring the edges of this snowy little planet. Of course the little planet is planet Earth, shown in a nadir-to-zenith, around-the-horizon, little planet projection. The spherical panoramic image mosaic maps a view from Siilinjärvi in eastern Finland. Flat ice crystals, like those more often found in high, thin clouds, are gently fluttering in very cold air near the surface. The pillars of light appear as their briefly horizontal facets reflect upward directed light from ground sources downward, toward the observer. In fact, the fluttering crystals produce an effect analogous to the shimmering columns of moonlight or sunlight reflected by surface waves across water.

What your company can learn from NASA tragedies

Scientists have been researching how NASA recognizes "near-miss" events ever since the Columbia shuttle was destroyed in flight 11 years ago Saturday. A new study finds recognition of near-misses goes up when leaders emphasize project significance and weigh safety over other goals.
