#Can supercapacitor wafers make power cords obsolete? Vanderbilt University rightoriginal Studyposted by David Salisbury-VU on May 22 2014imagine a future in which plugs and external power sources no longer limit our electrical gadgets.

The new device that Pint and Westover have developed is a supercapacitor that stores electricity by assembling electrically charged ions on the surface of a porous material instead of storing it in chemical reactions the way batteries do.

As a result supercaps can charge and discharge in minutes instead of hours and operate for millions of cycles instead of thousands of cycles like batteries.

and Westover report that their new structural supercapacitor operates flawlessly in storing and releasing electrical charge while subject to stresses or pressures up to 44 psi and vibrational accelerations over 80 g (significantly greater than those acting on turbine blades in a jet engine).

Furthermore the mechanical robustness of the device doesn t compromise its energy storage capability. n an unpackaged structurally integrated state our supercapacitor can store more energy

and operate at higher voltages than a packaged off-the-shelf commercial supercapacitor even under intense dynamic

One area where supercapacitors lag behind batteries is in electrical energy storage capability: Supercaps must be larger and heavier to store the same amount of energy as lithium-ion batteries.

However the difference is not as important when considering multifunctional energy storage systems. attery performance metrics change when you re putting energy storage into heavy materials that are needed already for structural integritysays Pint. upercapacitors store ten times less energy than current lithium-ion batteries

and solidifies it forms an extremely strong mechanical bond. he biggest problem with designing load-bearing supercaps is preventing them from delaminatingsays Westover. ombining nanoporous material with the polymer electrolyte bonds the layers together tighter than superglue. he use

of silicon in structural supercapacitors is suited best for consumer electronics and solar cells but Pint and Westover are confident that the rules that govern the load-bearing character of their design will carry over to other materials such as carbon nanotubes and lightweight porous metals like aluminum.

#New transistors offer high output at low voltage A new type of transistor could pave the way for fast computing devices that would use very low energy including smart sensor networks and implanted medical devices.

Called a near broken-gap tunnel field effect transistor (TFET) the new device uses the quantum mechanical tunneling of electrons through an ultrathin energy barrier to provide high current at low voltage.

Tunnel field effect transistors are considered to be a potential replacement for current CMOS transistors as device makers search for a way to continue shrinking the size of transistors and packing more transistors into a given area.

The main challenge facing current chip technology is that as size decreases the power required to operate transistors does not decrease in step.

Various new types of transistor architecture using materials other than the standard silicon are being studied to overcome the power consumption challenge. his transistor has previously been developed in our lab to replace MOSFET transistors for logic applications

To improve amplification the researchers moved all the contacts to the same plane at the top surface of the vertical transistor.

#Calculations find best phosphors for better LEDS University of California Santa barbara rightoriginal Studyposted by Sonia Fernandez-UCSB on November 12 2013new research makes it possible to optimize phosphorsâ##a key component in white

LED lightingâ##allowing for brighter more efficient lights. hese guidelines should permit the discovery of new and improved phosphors in a rational rather than trial-and-error mannersays Ram Seshadri a professor in the department of materials at University of California

and postdoctoral associate researcher Jakoah Brgoch appear in The Journal of Physical chemistry C. LED (light-emitting diode) lighting has been a major topic of research due to the many benefits it offers over traditional incandescent or fluorescent lighting.

LEDS use less energy emit less heat last longer and are less hazardous to the environment than traditional lighting.

and televisions LED TECHNOLOGY is becoming more popular as it becomes more versatile and brighter. According to Seshadri all of the recent advances in solid-state lighting have come from devices based on gallium nitride LEDS a technology that is largely credited to UC Santa barbara materials professor Shuji Nakamura who invented the first high-brightness

blue LED. In solid-state white lighting technology phosphors are applied to the LED chip in such a way that the photons from the blue gallium nitride LED pass through the phosphor

which converts and mixes the blue light into the green-yellow-orange range of light. When combined evenly with the blue the green-yellow-orange light yields white light.

The notion of multiple colors creating white may seem counterintuitive. With reflective pigments mixing blue and yellow yields green;

s LEDS become brighter for example as they are used in vehicle front lights they also tend to get warmer

#First supercapacitor on a silicon chip could power phones Vanderbilt University rightoriginal Studyposted by David Salisbury-VU on October 24 2013engineers have constructed the first supercapacitor made out of silicon.

and a variety of other electromechanical devices providing a considerable cost savings. f you ask experts about making a supercapacitor out of silicon they will tell you it is a crazy ideasays Cary Pint an assistant professor of mechanical engineering at Vanderbilt University who headed the development

These properties have allowed commercial supercapacitors which are made out of activated carbon to capture a few niche markets such as storing energy captured by regenerative braking systems on buses

Supercapacitors still lag behind the electrical energy storage capability of lithium-ion batteries so they are too bulky to power most consumer devices.

This allowed them to create surfaces with optimal nanostructures for supercapacitor electrodes but it left them with a major problem.

Silicon is considered generally unsuitable for use in supercapacitors because it reacts readily with some of chemicals in the electrolytes that provide the ions that store the electrical charge.

And when they used it to make supercapacitors they found that the graphene coating improved energy densities by over two orders of magnitude compared to those made from uncoated porous silicon and significantly better than commercial supercapacitors.

The novel supercapacitor design is described in a paper published in the journal Scientific Reports. The graphene layer acts as an atomically thin protective coating.

The supercapacitors would store excess electricity that the cells generate at midday and release it when the demand peaks in the afternoon. ll the things that define us in a modern environment require electricitysays Pint. he more that we can integrate power storage into existing materials

Mihail Roco a senior advisor for nanotechnology at the National Science Foundation called the work n important scientific breakthrough. t was roughly 15 years ago that carbon nanotubes were fashioned first into transistors the on-off switches

and its cousins. uch concerns arise from the demands that designers place upon semiconductors and their fundamental workhorse unit those on-off switches known as transistors.

For decades progress in electronics has meant shrinking the size of each transistor to pack more transistors on a chip.

But as transistors become tinier they waste more power and generate more heatâ##all in a smaller and smaller space as evidenced by the warmth emanating from the bottom of a laptop.

Many researchers believe that this power-wasting phenomenon could spell the end of Moore s Law named for Intel Corp. cofounder Gordon Moore who predicted in 1965 that the density of transistors would double roughly every two years

and low-power switching make carbon nanotubes excellent candidates to serve as electronic transistors. NTS could take us at least an order of magnitude in performance beyond where you can project silicon could take uswong said.

The Stanford team used this imperfection-immune design to assemble a basic computer with 178 transistors a limit imposed by the fact that they used the university s chip-making facilities rather than an industrial fabrication process.

A supercapacitor combines the best qualities of capacitors that charge in seconds and discharge energy in a burst and rechargeable batteries that charge slowly but release energy on demand over time.

The ideal supercapacitor would charge quickly, store energy, and release it as needed. esearchers have been trying for years to make energy storage devices like batteries and supercapacitors that work reliably in high-temperature environments,

but this has been given challenging the traditional materials used to build these devices, explains Pulickel Ajayan,

#Compact graphene device could shrink supercapacitors Monash University rightoriginal Studyposted by Emily Walker-Monash on August 5 2013monash U. AUS)# A new strategy to engineer graphene-based supercapacitors could make them viable

Supercapacitors are made generally of highly porous carbon impregnated with a liquid electrolyte to transport the electrical charge.

and the ability to recharge in seconds the drawback of existing supercapacitors is their low energy-storage-to-volume ratio#known as energy density.

Low energy density of five to eight watt-hours per liter means supercapacitors are unfeasibly large or must be recharged frequently.

and his team created a supercapacitor with energy density of 60 watt-hours per liter#comparable to lead-acid batteries and around 12 times higher than commercially available supercapacitors.#

#It has long been a challenge to make supercapacitors smaller lighter and compact to meet the increasingly demanding needs of many commercial uses#says Li.

They used liquid electrolytes#generally the conductor in traditional supercapacitors#to control the spacing between graphene sheets on the subnanometer scale.

For more than ten years, engineers have been worrying that they are running out of tricks for continuing to shrink silicon transistors.

Intel s latest chips have transistors with features as small as 14 nanometers, but it is unclear how the industry can keep scaling down silicon transistors much further or

what might replace them. A project at IBM is now aiming to have built transistors using carbon nanotubes ready to take over from silicon transistors soon after 2020.

According to the semiconductor industry s roadmap transistors at that point must have features as small as five nanometers to keep up with the continuous miniaturization of computer chips.

That s where silicon scaling runs out of steam, and there really is nothing else,

by offering a practical way to make both smaller and faster transistors, he says. In 1998, researchers at IBM made one of the first working carbon nanotube transistors.

a prediction originating in 1965 that the number of transistors that could be crammed into a circuit would double every two years.

Now it is working on a transistor design that could be built on the silicon wafers used in the industry today with minimal changes to existing design and manufacturing methods.

The design was chosen in part based on simulations that evaluated the performance of a chip with billions of transistors.

Those simulations suggest that the design chosen should allow a microprocessor to be five times as fast as a silicon one using the same amount of power.

IBM s chosen design uses six nanotubes lined up in parallel to make a single transistor.

and switches the transistor on and off to represent digital 1s and 0s. The IBM team has tested nanotube transistors with that design,

and filters out the tubes with the right properties for transistors using a modified version of a machine used to filter molecules such as proteins in the pharmaceutical industry.

It uses electric charge to separate semiconducting nanotubes useful for transistors from those that conduct electricity like metals

and can t be used for transistors. Last year researchers at Stanford created the first simple computer built using only nanotube transistors.

But those components were bulky and slow compared to silicon transistors says However, for now IBM s nanotube effort remains within its research labs, not its semiconductor business unit.

there s little else that shows much potential to take over from silicon transistors in that time frame.

and unlike carbon nanotubes, they don t behave similarly to silicon transistors, says Hannon. Subhasish Mitra, a professor who worked on the project.
