#Running the color gamut If LCD TVS start getting much more colorful and energy-efficient in the next few years,
Quantum dots are light-emitting semiconductor nanocrystals that can be tuned by changing their size, nanometer by nanometer to emit all colors across the visible spectrum.
QD Vision has developed an optical component that can boost the color gamut for LCD televisions by roughly 50 percent,
Last June, Sony used QD Vision product, called Color IQ, in millions of its Bravia riluminostelevisions, marking the first-ever commercial quantum dot display.
In September, Chinese electronics manufacturer TCL began implementing Color IQ into certain models. These are currently only available in China,
Replacing the bulb In conventional LCD TVS pixels are illuminated by a white LED backlight that passes through blue, red,
and green filters to produce the colors on the screen. But this actually requires phosphors to convert a blue light to white;
Manufacturers can potentially boost color by incorporating more LEDS, but this costs more and requires more energy to run.
Manufacturers use a blue LED in the backlight, but without the need for conversion phosphors.
LCD TVS equipped with Color IQ produce 100 percent of the color gamut, with greater power efficiency than any other technology. he value proposition is that you are not changing the display,
Other technologies, called organic light-emitting diode (OLED) displays, use an organic compound to reach upward of 100 percent of the color gamut
LCD TVS made with Color IQ are just as colorful but are made for a few hundred dollars less
on implementing quantum dots into electronic devices. In a study funded by MIT Deshpande Center for Technological Innovation, Coe-Sullivan, QD Vision cofounder Jonathan Steckel Phd 6,
and others developed a pioneering technique for producing quantum dot LEDS (QLEDS). To do so, they sandwiched a layer of quantum dots, a few nanometers thick, between two organic thin films.
Coe-Sullivan enrolled in 15.390 (New Ventures) to further develop a business model. hat led to the more rigorous formation of a sales and marketing plans,
the company eventually caught the eye of Sony, and last year became the first to market with a quantum dot display.
Along with Color IQ-powered LCD TVS, Amazon released a quantum dot Kindle last year, and Asus has a quantum dot notebook. nd there nothing in between that quantum dots can address,

#Bacteria become genomic tape recorders MIT engineers have transformed the genome of the bacterium E coli into a long-term storage device for memory.
They envision that this stable erasable and easy-to-retrieve memory will be suited well for applications such as sensors for environmental and medical monitoring.

which is why we re viewing it as a tape recorder because you can direct where that signal is written Lu says.

The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.
Prepared to send sizeable chunks of data at any given time the amplifiers stay at maximum voltage eating away power more than any other smartphone component and about 75 percent of electricity consumption in base stations#and wasting
But Eta Devices has developed a chip (for smartphones) and a shoebox-size module (for base stations) based on nearly a decade of MIT research to essentially switch gears to adjust voltage supply to power amplifiers as needed cutting the waste.
You can look at our technology as a high-speed gearbox that every few nanoseconds modulates the amount of power that the power amplifier draws from the battery explains Joel Dawson Eta Devices chief technology officer
and a former associate professor of electrical engineering and computer science who co-invented the technology. That turns out to be the key to keeping the efficiency very high.
When trialed in a base station last year Eta Devices module became the first transmitter for 4G LTE networks to achieve an average efficiency greater than 70 percent Dawson says.
Eta Devices has entered also conversations with major manufacturers of LTE-enabled smartphones to incorporate their chips by the end of next year.
If all midsized carrier networks were to replace current radio amplifiers with Eta Devices technology he says the reduction in greenhouse gases would be equivalent to taking about 5 million cars off the road.
In 2008 Dawson and Perreault who directs the Power Electronics Research Group submitted an early concept of the Eta technology then called asymmetrical multilevel outphasing (AMO) to an Innovation Teams
The AMO technology was a new transmitter architecture where algorithms could choose from different voltages needed to transmit data in each power amplifier
A paper detailing the technology was presented at that year s IEEE Radio frequency Integrated circuits Symposium. That Deshpande Center grant was big in terms of the funding
#Spinning out a company has been the best way to validate the technology especially with novel power-electronics hardware Dawson says.

When a DNA sample is exposed to this chip any strands that match the target sequences are trapped on the biochip.
After the laser-cut materials are layered together a microprocessor and one or more small motors are attached to the top surface.
the motors are synchronized by the microprocessor. Each leg in turn has eight mechanical linkages and the dynamics of the linkages convert the force exerted by the motor into movement.
Because they build it with the electronics on first you can now choose which folds occur when.

Such patterns may be useful in directing cells through a microchip s channels or wicking moisture from a windshield.
But at the boundary itself, the camera sensor receives both red and blue light, so it averages them out to produce purple.
The sensor of a digital camera consists of an array of photodetectors millions of them, even in commodity devices.
it less expensive to design the sensor hardware so that it reads off the measurements of one row of photodetectors at a time.
which could enable its use as a broadband light detector. The new findings are published in the journal Physical Review Letters in a paper by graduate student Alex Frenzel Nuh Gedik and three others.
This behavior is similar to that of traditional semiconductors such as silicon and germanium. But if the graphene starts out with high electron concentration the pulse decreases its conductivity the same way that a metal usually behaves.
and the bottom electrode the electron concentration of graphene could be tuned. The researchers then illuminated graphene with a strong light pulse
Our experiment reveals that the cause of photoconductivity in graphene is very different from that in a normal metal or semiconductors,
The researchers say the work could aid the development of new light detectors with ultrafast response times and high sensitivity across a wide range of light frequencies from the infrared to ultraviolet.
Practical application of such a detector would therefore require increasing absorption efficiency such as by using multiple layers of graphene,

while letting much more light pass through. Wetzstein envisions that commercial versions of a vision-correcting screen would use the same technique.
Then came diode-pumped solid-state (DPSS) lasers including disk and fiber that first transfer energy from diode lasers into a medium usually a crystal before converting it into a laser beam.
But the Terablade aptly called a direct-diode laser uses light directly from the diodes skipping the DPSS conversion step
Recently, scientists have explored ways to improve the efficiency of solar-thermal harvesting by developing new solar receivers and by working with nanofluids.

For powering remote automated environmental sensors even a tiny amount of energy might be sufficient;
which can be used to power microelectromechanical devices and small electronic devices. He adds Getting power from a condensation process is definitely a novel idea as condensation is used mainly for thermal management.#
But this requires an uninterrupted continuous path between the transmitter and the receiver which is obviously not ideal for consumer products Soljacic says.
Witricity s system of transmitters and receivers with magnetic coils on the other hand efficiently transfers power over longer distances says CEO Alex Gruzen 84 SM 86.
The transmitter emanated a magnetic field oscillating at megahertz frequencies which the receiver matched ensuring a strong coupling between the units
and weak interaction with the rest of the environment including nonmetallic materials and humans. In fact they demonstrated that they could light the bulb at roughly 45 percent efficiency with all six researchers standing in between the two coils.
when adding more receiver coils power transfer efficiency climbs by more than 10 percent. In that experiment they used larger transmitting coils
We expect to have much more of these embedded electronic devices in people over the next decade or so t
For example, many radar antennas are housed in spherical domes, which can collapse catastrophically in very high winds.
For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical engineering and Computer science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets,
it also solves one of the problems that has bedeviled previous attempts to design networks-on-chip:
In today chips, all the cores typically somewhere between two and six are connected by a single wire,
In a network-on-chip, each core is connected only to those immediately adjacent to it. ou can reach your neighbors really quickly,
Every core on a chip has its own cache a local, high-speed memory bank in which it stores frequently used data.
Most chips address this question with a protocol called noopy, because it involves snooping on other corescommunications.
But in a network-on-chip data is flying everywhere, and packets will frequently arrive at different cores in different sequences.
and their colleagues solve this problem by equipping their chips with a second network, which shadows the first.
During each interval, the chip 36 cores are given different, hierarchical priorities. Say, for instance, that during one interval,
