a thin, transparent film made from microscopic tubes called carbon nanotubes (CNTS), aligned parallel to the plane of the film.
gasgetting CNT films to emit sound is not the same as producing good-quality sound over the whole frequency range of human hearing,
So while the CNT speakers might have valuable applications such as sonar#they work perfectly well underwater#it isn't yet clear
One of the ways in which#to improve sound output is to surround the CNT film with a gas that has a lower heat capacity than air,
All things considered, Barnard and colleagues conclude that a high power CNT loudspeaker is feasible, but it won't be simple.
The CNT films will need probably to be enclosed and immersed in xenon, for example, which would pose serious challenges for making robust"wearable#speakers.

#Wearable sensor clears path to long-term EKG EMG monitoring Researchers from North carolina State university have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography
The new nanowire sensor is comparable to the wet sensors in terms of signal quality, but is a"dry"electrode-it doesn't use a gel layer,
because the nanowires are inlaid in the polymer.""The sensors stem from Zhu's earlier work to create highly conductive and elastic conductors made from silver nanowires,
and consist of one layer of nanowires in a stretchable polymer. The new sensor is also more accurate than existing technologies at monitoring electrophysiological signals
when a patient is in motion.""The silver nanowire sensors conform to a patient's skin, creating close contact,
"Zhu says.""And, because the nanowires are so flexible, the sensor maintains that close contact even when the patient moves.
The nanowires are also highly conductive, which is key to the high signal quality.""The new sensors are also compatible with standard EKG
-and EMG-reading devices.""I think these sensors are essentially ready for use, "Zhu says"The raw materials of the sensor are comparable in cost to existing wet sensors,

MOLDED IMAGES Previously, it was impossible to make nanopillars through cheap molding processes because the pillars were made from materials that preferred adhering to the mold rather than whatever surface they were supposed to cover.

when an optimal amount of PID2 was added the highest ever for solar cells made up of two types of polymers with fullerene
In order for a current to be generated by the solar cell electrons must be transferred from polymer to fullerene within the device.
But the difference between electron energy levels for the standard polymer-fullerene is large enough that electron transfer between them is difficult.
The tricky bit according to Rice university chemist Angel Martã is keeping the densely packed nanotubes apart before they re drawn together into a fiber.
Left to their own devices carbon nanotubes form clumps that are perfectly wrong for turning into the kind of strong conductive fibers needed for projects ranging from nanoscale electronics to macro-scale power grids.
Earlier research at Rice by chemist and chemical engineer Matteo Pasquali a coauthor of the new paper used an acid dissolution process to keep the nanotubes separated until they could be spun into fibers.
otherwise dampen the nanotubes ability to repel one another. Put enough nanotubes into such a solution and they re caught between the repellant forces
and an inability to move in a crowded environment Martã says. They re forced to align a defining property of liquid crystals
and tightly binds the nanotubes together says Martã an assistant professor of chemistry and bioengineering and of materials science and nanoengineering.
But to make macroscopic materials Martã s team needed to pack many more nanotubes into the solution than in previous experiments. s you start increasing the concentration the number of nanotubes in the liquid crystalline phase becomes more abundant than those in the isotropic (disordered) phase
The researchers discovered that 40 milligrams of nanotubes per milliliter gave them a thick gel after mixing at high speed
and filtering out whatever large clumps remained. t s like a centrifuge together with a rotary drummartã says of the mixing gear. t produces unconventional forces in the solution. eeding this dense nanotube gel through a narrow needle-like opening produced

because the setup is sealed. he nanotube electrolyte solution could be protected from oxygen and water which would have caused precipitation of the nanotubeshe says. t turns out that this is not a showstopper
because we want the nanotubes to precipitate and stick to each other as soon as they exit the sealed system through the needle.
The technology uses aluminum nanoparticles to create the vivid red blue and green hues found in today s top-of-the-line LCD televisions and monitors.
The color display technology delivers bright red blue and green hues from five-micron-square pixels that each contains several hundred aluminum nanorods.
By varying the length of the nanorods and the spacing between them researchers Stephan Link and Jana Olson showed they could create pixels that produced dozens of colors including rich tones of red green
because it s compatible with microelectronic production methods but until now the tones produced by plasmonic aluminum nanorods have been muted
and washed outsays Link associate professor of chemistry at Rice and the lead researcher on the PNAS study. he key advancement here was to place the nanorods in an ordered array. lson says the array setup allowed her to tune the pixel s color in two
ways first by varying the length of the nanorods and second by adjusting the length of the spaces between nanorods. his arrangement allowed us to narrow the output spectrum to one individual color instead of the typical muted shades that are produced usually by aluminum nanoparticlesshe adds.
Olson s five-micron-square pixels are about 40 times smaller than the pixels used in commercial LCD displays.
To make the pixels she used aluminum nanorods that each measured about 100 nanometers long by 40 nanometers wide.
She used electron-beam deposition to create arrays regular arrangements of nanorods in each pixel.
and the inherent directionality of the nanorods provides another advantage. ecause the nanorods in each array are aligned in the same direction our pixels produce polarized lighthe says. his means we can do away with one polarizer in our setup
By increasing the strength of the pili nanowires she improved their ability to clean up uranium and other toxic wastes.
The Geobacter biofilm encased by a network of nanowires and slime gives the bacteria a shield

Caltech materials scientist Julia Greer and her colleagues have developed a method for constructing new structural materials by taking advantage of the unusual properties that solids can have at the nanometer scale where features are measured in billionths of meters.
if you use the concept of the nanoscale to create structures and then use those nanostructures like LEGO to construct larger materials you can obtain nearly any set of properties you want.
You can create materials by design. he researchers use a direct laser writing method called two-photon lithography to ritea three-dimensional pattern in a polymer by allowing a laser beam to crosslink
what they call three-dimensional nanolattices that are formed by a repeating nanoscale pattern. After the patterning step they coated the polymer scaffold with a ceramic called alumina
(i e. aluminum oxide) producing hollow-tube alumina structures with walls ranging in thickness from 5 to 60 nanometers and tubes from 450 to 1380 nanometers in diameter.
and prodding materials on the nanoscale they squished stretched and otherwise tried to deform the samples to see how they held up.
They found that the alumina structures with a wall thickness of 50 nanometers and a tube diameter of about 1 micron shattered when compressed.
However compressing lattices with a lower ratio of wall thickness to tube diameter#where the wall thickness was only 10 nanometers#produced a very different result. ou deform it
when you reduce these structures down to the point where individual walls are only 10 nanometers thick both the number of flaws
and body scanners used in airport security. he research is published in Nature Nanotechnology. Current technological applications for terahertz detection are limited as they need to be kept extremely cold to maintain sensitivity.

A new one-step process to etch nanoscale spikes into silicon lets the maximum amount of sunlight reach a solar cell,

Black silicon is simply silicon with a highly textured surface of nanoscale spikes or pores that are smaller than the wavelength of light.
the phosphorous acid reduces the copper ions to copper nanoparticles. The nanoparticles attract electrons from the silicon wafer surface,
oxidizing it and allowing hydrogen fluoride to burn inverted pyramid-shaped nanopores into the silicon. Fine-tuning the process resulted in a black silicon layer with pores as small as 590 nanometers (billionths of a meter) that let through more than 99 percent of light.
By comparison, a clean, un-etched silicon wafer reflects nearly 100 percent of light. The spikes will still require a coating to protect them from the elements,
