Penn researchers make flexible, low-voltage circuits using nanocrystals
Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications in a world where electronics are becoming more pervasive. Finding materials with the right mix of performance and manufacturing cost, however, remains a challenge. Now researchers from the University of Pennsylvania has shown that nanoscale particles, or nanocrystals, of the semiconductor cadmium selenide can be "printed" or "coated" on flexible plastics to form high-performance electronics.

New device hides, on cue, from infrared cameras
Now you see it, now you don't. A new device invented at the Harvard School of Engineering and Applied Sciences can absorb 99.75 percent of infrared light that shines on it. When activated, it appears black to infrared cameras.

Following in Marie Curie's footsteps
More than a century ago, a brilliant young chemist and physicist named Marie Curie, won a Nobel Prize for her ground-breaking discoveries in radioactivity. Emma Martin Rodriguez, a post-doctoral researcher in Concordia's Department of Chemistry, is carrying on Curie's spirit of trail-blazing scientific inquiry, thanks to a prestigious research fellowship, created in Curie's name.

Transforming 'noise' into mechanical energy at nanometric level
A team of researchers at the Freie Universität Berlin, co-ordinated by José Ignacio Pascual (current leader of the Nanoimagen team at CIC nanoGUNE), have developed a method that enables efficiently using the random movement of a molecule in order to make a macroscopic-scale lever oscillate. The research was published in Science.

Tiny probes shine brightly to reveal the location of targeted tissues
Nanostructures called BRIGHTs seek out biomarkers on cells and then beam brightly to reveal their locations. In the tiny gap between the gold skin and the gold core of the nanoparticle, there is an electromagnetic hot spot that lights up the reporter molecules trapped there. BRIGHTs, which shine about 1.7 x 10^11 more brightly than isolated Raman reporters, are intended for use in noinvasive bioimaging.

Researchers build synthetic membrane channels out of DNA
Physicists at the Technische Universitaet Muenchen and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence that their nature-inspired nanostructures may also behave like biological ion channels. Their results could mark a step toward applications of synthetic membrane channels as molecular sensors, antimicrobial agents, and drivers of novel nanodevices.

Lava dots: Rice makes hollow, soft-shelled quantum dots
Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way to use molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots. The results appear online this week in the journal Nanotechnology.

Rice unveils super-efficient solar-energy technology
Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics is so effective it can even produce steam from icy cold water. Details of the solar steam method were published online today in ACS Nano. The technology's inventors said they expect it will first be used in sanitation and water-purification applications in the developing world.

Study reveals clues to cause of hydrogen embrittlement in metals
Hydrogen can easily dissolve and migrate within metals to make these otherwise ductile materials brittle and more prone to failures. Now, researchers at McGill University in Montreal and Ecole Polytechnique Federale de Lausanne in Switzerland, have shown that the physics of hydrogen embrittlement may be rooted in how hydrogen modifies material behaviors at the nanoscale. In a study published in Nature Materials, they present a model that can accurately predict the occurrence of hydrogen embrittlement.

Fabrication on patterned silicon carbide produces bandgap to advance graphene electronics
By fabricating graphene structures atop nanometer-scale "steps" etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.

Breakthrough nanoparticle halts multiple sclerosis
In a breakthrough for nanotechnology and multiple sclerosis (MS), a biodegradable nanoparticle delivers an antigen that tricks the immune system and halts MS in mice. The approach, the first that doesn't suppress the immune system, is being tested in a clinical trial for MS patients, but with white blood cells delivering the antigen. The nanoparticle is an easier, cheaper option and can be used in other immune-related diseases including Type 1 diabetes, food and airway allergies.
