#Breakthrough quantum dot hybrid LED is inexpensive and delivers vibrant color Light-emitting diodes (LEDS) are prevalent in everything from digital clocks to solar panels, traffic lights, electronic banners and signs, Christmas decorations,
as well as smartphone and tablet displays. However, LEDS are created using organic materials that can be costly for researchers.
The end result of the manufacturing process is that LEDS cost more for the consumer.
While LED lighting systems last longer, are more energy-efficient, and provide an improved color gamut above that of fluorescent lights,
cost-effective quantum dot (QD) hybrid LED could enable LED lighting system adoption on a mass scale.
University of Hiroshima (Japan) researchers created the new light-emitting diode using silicon quantum dot solution and a polymer solution on top of an indium-tin-oxide (ITO) glass ply that was used as the anode for the LED.
The silicon quantum dot solution was placed in the bottom of a glass vial that sat on a rotating stage.
The study is the first of its kind to produce silicon quantum dot LEDS by way of a solution-based process
and marks an advancement of LED TECHNOLOGY, seeing that the use of organic film as the electron transport in past LED production resulted in a decreased photoluminescence and an inaccurate color reproduction.
resulting in a more cost-efficient process by which to manufacture LEDS. Fluorescent bulbs are cheaper than LEDS,
with a box of fluorescent bulbs costing no more than a few dollars, but consume more energy and lead to higher energy bills.
LEDS are more expensive up-front, with some costing as high as $70 a piece,
QLED TVS, like LED lighting systems, cost more up-front than traditional LCD TVS but are cost-efficient and color-effective.
Sony worked with Quantum dot supplier QD Vision to produce its own QD TVS in 2013 under the riluminouslabel,
but Samsung is one of the major manufacturers now advancing QD technology over OLED with the recent release of its Super Ultra High-Definition TVS (SUHD)

coated the foil with electrode-laden, conductive material; and then replaced the 300mah battery inside Samsung Gear 2 smartwatch with the coated kirigami-cut aluminum foil.
To test out the new battery, the researchers connected the aluminum foil with two pliers, attached it to both the Gear 2 smartwatch
and an elastic band that was pulled up from the wrist to the bicep, and stretched the lithium-ion battery to 150%of its original size.
and the Gear 2 smartwatch continued its video playback. ASU leader Dr. Jiang says that the kirigami-based design is the secret to the future of flexible electronics. he kirigami-based methodology can be expanded readily to other applications to develop highly stretchable devices
and thus deeply and broadly impact the field of stretchable and wearable electronics, he said. ther applications may include smart bracelets and smart headbands.
The results and other details regarding the study can be found in the Scientific Reports journal as well as Nature magazine.

Sinitskii turned these short whiskers into titanium trisulfide transistors, and tested their performance, confirming that they had expected the properties, and abilities.
What this means is that purely scientific proofs of concept like current graphene computer chips might be made fully digital
Right now, graphene lack of a useful bandgap means that graphene computers are limited to analog computation only;
and off by the same process as a silicon transistor could let it power continued increases in processing speed without requiring engineers to invent a whole new sort of logical architecture.
Its achievable bandgap also makes silicon highly absorptive to incoming energy sources like photons, and today most solar cells are based on silicon.
In theory, the success with simple transistors implies that this material could also help continue advances in solar cells.
is that there was only a few months needed to take this purely theoretical 2d substance from a computer simulation to practical, working transistors.
The pure transistor density already achieved with graphene, combined with the ability to create relatively ormaldigital architecture,

Headlamp arrays offer promise, once the US signs on Ford system uses LED LIGHTS separate from the headlamp systems.
but such technologies change the transistor design, and thus the manufacturing process for solar panels. Their impacts tend to be limited by cost concerns, more than anything else.
These researchers chose to accept the absorptive abilities of current silicon transistors, and instead looked to make the light conform to the panels.
there is huge potential in offering such large improvements without the need to completely reinvent the transistor manufacturing process.

The resulting, lower-wavelength photons can move on to be absorbed by the transistors of the solar panel as normal,
Wi-fi radio broadcasts are a form of energy that a simple antenna can pick up. Until now, Wi-fi receivers have all been designed to harvest the information that these broadcasts carry.
Talla simply connected an antenna to a temperature sensor placed it close to a Wi-fi router
and measured the resulting voltages in the device and for how long it can operate on the remote power source alone.
Even more ambitiously, the team also connected a camera to their antenna. This was a low-power sensor capable of producing 174×144 pixel black and white images,
which requires 10.4 millijoules of energy per picture. To store energy, they attached a low leakage capacitor to the camera
which activates when the capacitor is charged and continues operating until the voltage drops to 2. 4 Volts.
The images were stored in a 64kb random access memory (RAM. In the subsequent tests, the camera performed remarkably well. he battery-free camera can operate up to about five meters from the router,
perhaps connected to a movement sensor to trigger the camera when something moves in its field of view,

#Rare case uncovers missing clue to Fragile X Fragile X syndrome may not only be a problem of receivers in the brain letting in too much information.
A new study finds that transmitters may be sending out too much data, as well. The findings raise the possibility that drugs recently tested as treatments for fragile X may be ineffective, at least in part,
because they only dialed down the brain receivers, presumably leaving transmitters on overdrive. Scientists made the discovery by studying the case of someone who doesn even have the disordernly two of its classic symptoms.
In patients with fragile Xhe most common cause of inherited intellectual disability key gene is disabled completely
Like radio transmitters and receivers, brain cells send and receive transmissions in fine-tuned ways that separate the signals from the noise.
Until recently, most fragile X research has focused on problems with overly sensitive receivers, those that allow in too much information.
published in the Proceedings of the National Academy of Sciences, suggests that fragile X likely also causes overactive transmitters that send out too much information. he mechanisms that researchers have thought long were the entirety of the problem with fragile X are obviously still very much in play,
In other words, the patient brain cells had entirely normal receivers, which appeared to work in ways that were indistinguishable from those in healthy people. his single point mutation does not seem to affect the classical,
Surprisingly, the fruit fly studies indicated that this single mutation increased the number of transmitters in brain cells, implicating a fundamental problem in

#Hybrid crystals fuse semiconductors and metal Tomorrow's computers and electronics will require extremely small high-quality circuits.
Comprised of both a semiconductor and metal the material has a special superconducting property at very low temperatures.
Nanowires are extremely thin nanocrystal threads used in the development of new electronic components like transistors and solar cells.
The atoms sit in a perfectly ordered lattice in the nanowire crystal not only in the semiconductor and the metal but also in the transition between the two very different components which is significant in itself explains Peter Krogstrup an assistant professor who helped develop the contact.
He thinks it opens many opportunities to make new types of electronic components on the nanoscale to study the electrical properties with much greater precision than before In their publication in Nature Materials the research group has demonstrated this perfect contact
and its properties and has shown also that they can make a chip with billions of identical semiconductor-metal nanowire hybrids.
We think that this new approach could ultimately form the basis for future superconducting electronics says Jespersen.

"The chip is designed to funnel blood through a field of microscopic triangle-shaped posts. The posts are arranged so that every two posts channels cells towards the tip of a third post.
and continue through the chip until reaching the next tip. However, CTC clusters are left stuck at the tip due to forces pulling them down the post in opposite directions.

The new technology uses implanted sensors sending wireless signals to the artificial limb's built-in computer, enabling subconscious, real-time control and faster, more natural responses and movements.
It works by laying sensors on the skin of the vestigial limb, which picks up electrical impulses that control, for example, an artificial arm.
these sensors pick up electric impulses from more than one muscle. This degrades performance, requires a lot of practice to operate properly,
One answer to this is to use more precise sensor arrangements that make the limb, for all practical purposes, mind-controlled.
#New process prints electroluminescent layers directly onto three-dimensional objects Electroluminescent (EL) panels are found in many electronics applications, particularly as backlighting for LCD displays, keypads, watches,

Essentially the equivalent of a capacitor when used in an AC (Alternating current) circuit, EL panels encase their light-emitting material between two electrodes.
In standard panels, one electrode is generally clear glass or plastic coated with a transparent conductive coating,
while the opaque rear electrode is made generally from a reflective metal foil. In the KIT/Binder EL panel,
