Public Release: 8-Dec-2014
New technique allows low-cost creation of 3-D nanostructures
Researchers have developed a new lithography technique that uses nanoscale spheres to create 3-D structures with biomedical, electronic and photonic applications. The new technique is less expensive than conventional methods and does not rely on stacking two-dimensional patterns to create 3-D structures.

Finding the Achilles' heel of GaN-based LEDs in harsh radiation environments
Toyohashi Tech researchers in Japan have discovered that proton irradiation of gallium nitride causes more damage in p-type material than n- doped layers. This unexpected finding is important for the application of GaN-based devices in extreme environments.

Light propagation in solar cells made visible
How can light which has been captured in a solar cell be examined in experiments? Jülich scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

When noise gets electrons moving
Studying the motion of electrons in a disordered environment is no simple task. Often, understanding such effects requires a quantum simulator designed to expose them in a different physical setup. This was precisely the approach adopted by Denis Makarov and Leonid Kon'kov in a new study published in EPJ B. They relied on a simulator of electronic motion subjected to noise stemming from a flux of sound waves.

Electron pairs on demand
Physicists from Leibniz University Hannover and from the Physikalisch-Technische Bundesanstalt have demonstrated for the first time the on-demand emission of electron pairs from a semiconductor quantum dot and verified their subsequent splitting into two separate conductors. Their results -- which could be important for quantum computers and quantum cryptography -- have been published in the current online issue of Nature Nanotechnology.

Geckos are sticky without effort
Scientists have studied a variety of features in geckos such as the adhesive toe pads on the underside of the feet with which geckos attach to surfaces with remarkable strength. UC Riverside biologists have now conducted experiments in the lab on live and dead geckos that show, for the first time, that dead geckos can adhere to surfaces with the same strength as living geckos. The research could have applications in the field of robotics.

Colorful nano-guides to the liver
Jena scientists have been successful in producing highly specific nanoparticles. Depending on the bound dye the particles are guided to the liver or to the kidney and deliver their payload of active ingredients directly to the targeted tissue. Moreover, the dyes enable the tracking of the transport processes by intravital microscopy or, in a non-invasive way, by multi spectral optoacoustic tomography. The reduction of cholesterol production induced by siRNA served as the proof-of-principle for the developed method.

Wireless nanorod-nanotube film enables light stimulation of blind retina
Scientists have developed a new light-sensitive film that could one day form the basis of a prosthetic retina to help people suffering from visual impairment. Hebrew University researchers collaborated with Tel Aviv University and Newcastle University colleagues to develop a novel device that absorbs light and stimulates neurons without using wires or external power. Combining semiconductor nanorods and carbon nanotubes, it could potentially form part of a future prosthetic device that replaces damaged retinal cells.

A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial 'nanodrills' assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells' outer membranes.

'Smart dust' technology could reshape space telescopes
Scientists at Rochester Institute of Technology and the NASA Jet Propulsion Laboratory are exploring a new type of space telescope with an aperture made of swarms of particles released from a canister and controlled by a laser. These floating lenses would be larger, cheaper and lighter than apertures on conventional space-based imaging systems like NASA's Hubble and James Webb space telescope.

Possible read head for quantum computers
Nitrogen-vacancy centers in diamonds could be used to construct vital components for quantum computers. But hitherto it has been impossible to read optically written information from such systems electronically. Using a graphene layer, a team of scientists headed by Professor Alexander Holleitner of the Technische Universität München has now implemented just such a read unit.

Scanning tunneling microscopy: Computer simulations sharpen insights into molecules
The resolution of scanning tunneling microscopes can be improved dramatically by attaching small molecules or atoms to their tip. The resulting images were the first to show the geometric structure of molecules and have generated a lot of interest among scientists over the last few years. Scientists from Forschungszentrum Jülich and the Academy of Sciences of the Czech Republic in Prague have now used computer simulations to gain deeper insights into these new imaging techniques.

New electrolyte for the construction of magnesium-sulfur batteries
The Helmholtz Institute Ulm established by Karlsruhe Institute of Technology is pushing research relating to batteries of the next and next-but-one generations: A research team has now developed an electrolyte that may be used for the construction of magnesium-sulfur battery cells. With magnesium, higher storage densities could be achieved than with lithium. Moreover, magnesium is abundant in nature, it is non-toxic, and does not degrade in air. The new electrolyte is now presented in the journal Advanced Energy Materials.

Particles, waves and ants
Particles or waves traveling through disordered media are scattered at small impurities. Surprisingly, the density of these impurities does not affect the overall dwell time the particle -- or wave -- spends inside the medium. This remarkable finding applies not only to particles and waves, but also to crawling ants or drunken sailors hitting streetlamps.
