Nanotechnology news

	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 of properties that are not typically seen together: high conductivity, flexibility, and room-temperature self-healing. The gel could potentially offer self-healing for a variety of applications, including flexible electronics, soft robotics, artificial skins, biomimetic prostheses, and energy storage devices.
	Quantum dot solar windows go non-toxic, colorless, with record efficiency A luminescent solar concentrator is an emerging sunlight harvesting technology that has the potential to disrupt the way we think about energy; It could turn any window into a daytime power source.
	Big questions about risk assessment of nanomaterials When it comes to nanotechnology, Australians have shown strong support for regulation and safety testing.
	Physicists build stable diffraction structure in atomically thin graphene Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed the delocalization of molecules at the thinnest possible grating, a mask milled into a single layer of atoms. The presented experiments explore the technical limits of matter wave technologies and respond to a famous Gedanken experiment by Einstein and Bohr of almost 80 years ago. The results are published in the journal Nature Nanotechnology.
	Research trio outlines ways nanodiamonds are being used to treat cancer (Phys.org)—A trio of researchers, Dean Ho, with UCLA in the U.S., Chung-Huei Katherine Wang, with BRIM Biotechnology Inc., in Taipei and Edward Kai-Hua Chow with the National University of Singapore, has published a review in Science Advances, of the ways nanodiamonds are being used in cancer research and offer insights into the ways they may be used in the future.
	Glitter from silver lights up Alzheimer's dark secrets Scientists have caught a glimpse of the elusive toxic form of the Alzheimer's molecule, during its attempt to bore into the outer covering of a cell decoy, using a new method involving laser light and fat-coated silver nano-particles.
	Self-assembled aromatic molecular stacks, towards modular molecular electronic components Being able to effectively tune the electron-transport properties of a single-molecule has been a long-standing issue towards the crystallization of molecular electronics, where individual molecules mimic the behavior of common electronic components as a true alternative to conventional silicon devices. To functionalize electron transport properties, each and every individual molecule must be precisely aligned in place with sub-nanometer precision. In that sense, stacks of self-assembled aromatic components in which non-covalently bound π-stacks act as replaceable modular components are promising building blocks.

Physics news

	Magnon, meet phonon: Magnetoelastic waves can drive magnetic bubbles through photoexcitation (Phys.org)—Research in spintronics (short for spin transport electronics – the study of the electron's intrinsic spin and associated magnetic moment in solid-state devices) continues to be focused on methods for exercising precise control of magnetic domain walls, which are topological solitons (that is, phase defects in the spin alignment separating magnetic domains) separating magnetic domains. Moreover, spin momentum can be delivered to and exchanged with magnetic domain walls using magnons – quantized spin waves – in both metals and insulators.
	How long does it take an electron to tunnel? The combination of ab-initio numerical experiments and theory shows that optical tunnelling of an electron from an atom can occur instantaneously.
	Dynamics of nuclear fission at low excitation energy The mechanisms of nuclear fission, especially the origin of asymmetric mass division in the low-excitation region of U and Pu, are still not clear. There are many conflicting arguments to explain the experimental data, making a proper prediction of unmeasured quantities quite difficult.
	Birth of photo-sensitive magnets: New functional photonic materials and devices based on magnetism Digital information technology has great impact on our lives that has strongly motivated scientists to look for faster and more energy-efficient ways to process streams of digital signals. Recently, electrical engineers has proposed using not just electricity but also light to send the signals even inside semiconductor chips, and condensed matter physicists are studying ways of exploiting the spin instead of the charge of electrons for electronic devices.
	Single-crystal phosphors suitable for ultra-bright, high-power white light sources The Optical Single Crystals Group at NIMS, in collaboration with Tamura Corporation and Koha Co., Ltd., successfully developed single-crystal phosphors that use a blue LD (laser diode) as an excitation light source, are suitable for ultra-bright, high-power white lighting, and have outstanding temperature characteristics.

	Flood damage after Katrina could have been prevented, expert says A decade after hurricane Katrina hit New Orleans, experts say the flooding that caused over 1,800 deaths and billions of dollars in property damage could have been prevented had the U.S. Army Corps of Engineers retained an external review board to double-check its flood-wall designs.
Fire damage to soils sets back bushfire recovery Soils in areas hit by bushfires like the Sampson Flat fire may take several years to recover, say University of Adelaide soil scientists starting a new study into the effects of bushfires on soils.
	Geologic record of ancient earthquakes and tsunamis will help understand future impacts The devastating 2004 Indian Ocean earthquake and tsunami that killed 230,000 people has raised questions among coastal residents about when the next big tsunami will strike. It's a question that University of Rhode Island geologist Simon Engelhart knows cannot be answered with any precision.
	Organic is not always the best choice for you or the planet Eating organically grown food might make you feel good inside, but a University of Queensland researcher says organic agriculture is not necessarily sustainable and— contrary to popular belief—often relies on chemical sprays.
	Christmas Island plate corals hit hard by disease A survey of Christmas Island reefs has revealed twice as much plate coral was destroyed by a 2008 disease outbreak than previously feared.
	Water covers 70 percent of the Earth's surface, but only a fraction is fresh Fresh water—connecting and sustaining all aspects of life on Earth, including food and energy—is in great danger. Moreover, scientists are worried not only about fresh water; they worry that we are not worried enough about fresh water, especially in light of growing concern over recent events, such as the prolonged California drought. The current Special Issue Section of Technology and Innovation - Journal of the National Academy of Inventors has a special section devoted to fresh water and the challenges it faces from us and from the changing environment.
Malformed fossil plankton reveal that heavy metal pollution might have contributed to world's largest extinction events Several Palaeozoic mass extinction events during the Ordovician and Silurian periods (ca. 485 to 420 to million years ago) shaped the evolution of life on our planet. Although some of these short-lived, periodic events were responsible for eradication of up to 85% of marine species, the exact kill-mechanism responsible for these crises remains poorly understood.
	NASA finds vegetation essential for limiting city warming effects Cities are well known hot spots - literally. The urban heat island effect has long been observed to raise the temperature of big cities by 1 to 3°C (1.8 to 5.4°F), a rise that is due to the presence of asphalt, concrete, buildings, and other so-called impervious surfaces disrupting the natural cooling effect provided by vegetation. According to a new NASA study that makes the first assessment of urbanization impacts for the entire continental United States, the presence of vegetation is an essential factor in limiting urban heating.
	Cracking open diamonds for messages from the deep earth Geochemist Yaakov Weiss deals in diamonds. Not the brilliant jewelry-store kind, but the flawed, dirty-looking ones used more for industry than decoration. Gem-grade diamonds are generally pure crystallized carbon, but many lower-grade stones contain so-called inclusions–chemical intruders bottled up inside the crystal. Inclusions lower the stone's value; but they contain worlds of information about the deep, inaccessible regions where diamonds come from. Their compositions speak to not only how diamonds form (and maybe how to find them), but other basic processes below.
	Purifying contaminated water with crab shells Copper and cadmium exist naturally in the environment, but human activities including industrial and agricultural processes can increase their concentrations. At high concentrations, copper can cause unwanted health effects such as nausea, while cadmium can be toxic to the kidneys.

	Community of soil bacteria saves wild tobacco plants from root rot Root bacteria are known to form symbiotic relationships with plants by improving the plants' supply of nutrients. Yet as scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, found recently, the bacteria actually play a much more profound role. During field experiments in Utah, in the western USA, researchers discovered that the right mixture of soil microbiota directly influences the survival of Nicotiana attenuata, a species of wild tobacco. Plants that had been unable to establish a protective alliance with the vitally important soil bacteria were susceptible to an infectious wilt disease that could kill them overnight. The pathogens that caused the disease had built up and spread because the researchers had been continuously growing this native plant in the same field. Moreover, a sterile medium had been used for germination before the plants had been planted out on the field, a procedure which prevente! d the plants from recruiting symbiotic bacteria early on, as they normally would do when germinating in nature. The results of the study emphasize the importance of crop rotation to prevent the buildup of soil borne diseases and reveal the complex ecology of plants, especially with respect to the multitude of beneficial and harmful microorganisms that interact with them.
