#Carbon nanotube finding could lead to flexible electronics with longer battery life Led by materials science Associate professor Michael Arnold
In addition to paving the way for improved consumer electronics this technology could also have specific uses in industrial and military applications.
In a paper published recently in the journal ACS Nano Arnold Gopalan and their students reported transistors with an on-off ratio that's 1000 times better and a conductance that's 100 times better than previous state-of-the-art carbon nanotube transistors.
so they could also be used to make flexible displays and electronics that can stretch and bend allowing you to integrate electronics into new places like clothing says Arnold.
The advance enables new types of electronics that aren't possible with the more brittle materials manufacturers are currently using.
Carbon nanotubes are single atomic sheets of carbon rolled up into a tube. As some of the best electrical conductors ever discovered carbon nanotubes have long been recognized as a promising material for next-generation transistors
which are semiconductor devices that can act like an on-off switch for current or amplify current. This forms the foundation of an electronic device.
However researchers have struggled to isolate purely semiconducting carbon nanotubes which are crucial because metallic nanotube impurities act like copper wires and short the device.
Researchers have struggled also to control the placement and alignment of nanotubes. Until now these two challenges have limited the development of high-performance carbon nanotube transistors.
The team's most recent advance also brings the field closer to realizing carbon nanotube transistors as a feasible replacement for silicon transistors in computer chips
Our carbon nanotube transistors are an order of magnitude better in conductance than the best thin film transistor technologies currently being used commercially

#Laser-induced graphene'super'for electronics: Flexible 3-D supercapacitors tested Rice university scientists advanced their recent development of laser-induced graphene (LIG) by producing
and testing stacked, three-dimensional supercapacitors, energy storage devices that are important for portable, flexible electronics. The Rice lab of chemist James Tour discovered last year that firing a laser at an inexpensive polymer burned off other elements and left a film of porous graphene, the much-studied atom-thick
lattice of carbon. The researchers viewed the porous, conductive material as a perfect electrode for supercapacitors or electronic circuits.
An electron microscope image shows the cross section of laser-induced graphene burned into both sides of a polyimide substrate.
The flexible material created at Rice university has the potential for use in electronics or for energy storage.

members of the Tour group have extended since their work to make vertically aligned supercapacitors with laser-induced graphene on both sides of a polymer sheet.
The sections are stacked then with solid electrolytes in between for a multilayer sandwich with multiple microsupercapacitors.
Capacitors use an electrostatic charge to store energy they can release quickly, to a camera's flash, for example.
Unlike chemical-based rechargeable batteries, capacitors charge fast and release all their energy at once when triggered.
Supercapacitors combine useful qualities of both--the fast charge/discharge of capacitors and high-energy capacity of batteries--into one package.
LIG supercapacitors appear able to do all that with the added benefits of flexibility and scalability.
-and-release characteristics of a supercapacitor. In testing, the researchers charged and discharged the devices for thousands of cycles with almost no loss of capacitance.
To show how well their supercapacitors scale up for applications, the researchers wired pairs of each variety of device in serial and parallel.
The vertical supercapacitors showed almost no change in electrical performance when flexed, even after 8, 000 bending cycles.
LIG supercapacitors of the same size offer three times the performance in power (the speed at which energy flows).

As a result an electrode particle swells as a whole i e. it increases in volume only to shrink again once the charges leave the particle.
This process may lead to instabilities in the electrode material in terms of structural changes and contact losses.
To produce an efficient electrode the researcher coated the vanadate-borate powder with reduced graphite oxide (RGO.
This increases conductivity while at the same time protecting the electrode particles. However it does not impede electrons

During initial trials with vanadate-borate electrodes which were made not with material coated in RGO the discharge capacity dropped drastically after 30 charge/discharge cycles

#New superconducting hybrid crystals A new type of'nanowire'crystals that fuses semiconducting and metallic materials on the atomic scale could lay the foundation for future semiconducting electronics.
The development and quality of extremely small electronic circuits are critical to how and how well future computers and other electronic devices will function.
The new material, composed of both a semiconductor and metal, has a special superconducting property at very low temperatures
and could play a central role in the development of future electronics.""Our new material was born as a hybrid between a semiconducting nanowire and its electronic contact.
Thus we have invented a way to make a perfect transition between the nanowire and a superconductor.
Nanowire and contact formed at the same time Nanowires are extremely thin nanocrystal threads used in the development of new electronic components
like transistors and solar cells. Part of the challenge of working with nanowires is creating a good transition between these nanowires and an electrical contact to the outside world.
not only in the semiconductor and the metal, but also in the transition between the two very different components,
Of course this opens many opportunities to make new types of electronic components on the nanoscale and in particular,

and its properties and has shown also that they can make a chip with billions of identical semiconductor-metal nanowire hybrids."

and that is why the research into nanowires is interesting for the largest electronics companies, "says Thomas Sand Jespersen.

#Toward quantum chips: Packing single-photon detectors on an optical chip is crucial for quantum-computational circuits Single-photon detectors are notoriously temperamental:
Of 100 deposited on a chip using standard manufacturing techniques only a handful will generally work.
In a paper appearing today in Nature Communications the researchers at MIT and elsewhere describe a procedure for fabricating
and testing the detectors separately and then transferring those that work to an optical chip built using standard manufacturing processes.
In addition to yielding much denser and larger arrays the approach also increases the detectors'sensitivity. In experiments the researchers found that their detectors were up to 100 times more likely to accurately register the arrival of a single photon than those found in earlier arrays.
You make both parts--the detectors and the photonic chip--through their best fabrication process which is dedicated
and then bring them together explains Faraz Najafi a graduate student in electrical engineering and computer science at MIT and first author on the new paper.
According to quantum mechanics tiny physical particles are counterintuitively able to inhabit mutually exclusive states at the same time. A computational element made from such a particle--known as a quantum bit
The researchers'process begins with a silicon optical chip made using conventional manufacturing techniques. On a separate silicon chip they grow a thin flexible film of silicon nitride upon
At both ends of the resulting detector they deposit gold electrodes. Then to one end of the silicon nitride film they attach a small droplet of polydimethylsiloxane a type of silicone.
They then press a tungsten probe typically used to measure voltages in experimental chips against the silicone.
and attach it to the optical Chip in previous arrays the detectors registered only 0. 2 percent of the single photons directed at them.
Even on-chip detectors deposited individually have topped historically out at about 2 percent. But the detectors on the researchers'new chip got as high as 20 percent.
That's still a long way from the 90 percent or more required for a practical quantum circuit but it's a big step in the right direction n

If they reach the other electrode, the electrons have a path within the battery, shorting out the circuit.
