which the company says could boost computing power of verything from smartphones to spacecraft. he company unveiled the industry first seven-nanometer chip that could hold more than 20 billion tiny switches or transistors for improved computing power.
The new chips could help meet demands of future cloud computing and Big data systems, cognitive computing, mobile products and other emerging technologies, according to IBM,
which developed the chip as part of a $3 billion research effort with Samsung and Globalfoundries at the State university of New york at Albany.
Most chips today in PCS and other devices use microprocessors between 14 and 22 nanometers.
Enabling the first 7nm node transistors is a significant milestone for the entire semiconductor industry as we continue to push beyond the limitations of our current capabilities,

along with the imbedded electronics, eventually got covered up with more layers of plastic. Of course Voxel8's printer is designed to do more than just print tiny drones.
The company will also be releasing new printing materials in order to try its hand at printing resistors, sensors and, for future models of its printer, even lithium-ion batteries.
in addition to the custom circuit boards that Voxel8's printers have perfected already.""We're talking about printing out a circuit at your desk in less than 30 minutes,
This represents a vast improvement over earlier options for printing custom circuit boards, a process that,
they'll also be able to try out unconventional geometries for their electronics, Oliver said. For example, rather than trying to get a rectangular circuit board to fit inside a curved object,
it will now be possible to customize the shape of a circuit so that it fits inside objects of any shape or size."
Light emitting diodes (LEDS) are now everywhere from consumer electronics like smart phones to light bulbs for home lighting.
The key to its success in replicating a sunny sky uses nanostructured materials to scatter light from LEDS in the same way tiny particles scatter sunlight in the atmosphere so-called Rayleigh scattering.
Illuminating research Only recently has the full utility of LEDS been realized for general lighting. While red and green LEDS had been in commercial use for more than a decade,
the missing color for producing white light was blue. Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura cracked the blue conundrum in the early 1990s.
Now, thanks to their work, white light LEDS are ubiquitous. In recognition of this energy saving invention, they received the Nobel prize in Physics last year.
Take LEDS for example. Research in blue LEDS started more than 40 years ago at Radio Corporation of America,
but changes in the company funding structure stymied their development for two decades until last year Nobel prize winners solved the materials problem
and receive data with high bandwidths as well as to detect trace molecules or bio-agents. Construction of our nanolaser required precise control over the shape and location of the adjacent gold nanoparticles.
That such nanostructures could even be made is because of the decades-long investment by the electronics industry in developing nanofabrication tools to make the tiny components in computers.
In addition to testing out different locations for the machine and communicating with local community members about how it works, the Janicki team's trial run in Senegal will also test out a system of sensors

The electronics that ecoatm reclaims can be mined for the valuable and rare metals they contain.

Whereas conventional microelectronics shuffle electrons around wires, in recent years, scientists have begun developing so-called microfluidic devices that shuffle liquids around pipes.
These devices can theoretically perform any operation a conventional electronic microchip can. Although microfluidic devices are dramatically slower than conventional electronics,
the goal is not to compete with electronic computers on traditional computing tasks such as word processing. Rather
"Current applications for microfluidic chips include serving as miniaturized chemistry and biology laboratories. Instead of performing experiments with dozens of test tubes, each droplet in a lab-on-a-chip can serve as a microscopic test tube,
The core of the new microfluidic chip, which is about half the size of a postage stamp,
The layout of the bars on these new microfluidic chips is analogous to the layout of circuits on microchips, controlling interactions among the droplets.
"Making the droplets smaller will allow the chip to carry out more operations, "Prakash said. The researchers now plan to make a design tool for these droplet circuits available to the public,
and a simple antenna with the receivers can pick up this energy. Talla demonstrated his claim by connecting an antenna to a temperature sensor
and placing it close to a Wi-fi router. The resulting voltage in the device was measured then
When the team connected a camera to their antenna the results were remarkable. Talla informed,"The battery-free camera can operate up to about five meters from the router,
which could run LED LIGHTS and even drive a miniature car! Sahin informed that his system could be hundreds times cheaper to build per unit area than solar tapping,
In the process, the electrodes are suspensions of small particles carried by a liquid and pumped through different compartments of the battery.
"We realized that a better way to make use of this flowable electrode technology was to reinvent the lithium ion manufacturing process".
"In the new method, the electrode material remained in a liquid state. Having the electrode in the form of tiny suspended particles reduces the path length for charged particles as they move through the material, a property known as tortuosity.
Less tortuous path simplifies production and proves cost effective. The new system leads to the production of battery that is more flexible and resilient.
#Flexible devices are a step closer For wearable technology a truly flexible electronic device is the goal.

#One step closer to a single-molecule device Researchers have designed a new technique to create a single-molecule diode,
and, in doing so, they have developed molecular diodes that perform 50 times better than all prior designs.
The group, under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, is the first to develop a single-molecule diode that may have real-world technological applications for nanoscale devices.
Their paper,"Single-Molecule Diodes with High On-Off Ratios through Environmental Control,"is published May 25 in Nature Nanotechnology."
"Our new approach created a single-molecule diode that has a high(>250) rectification and a high"on"current (0. 1 micro Amps),"says Venkataraman."
ever since its inception with Aviram and Ratner's 1974 seminal paper, represents the ultimate in functional miniaturization that can be achieved for an electronic device."
"With electronic devices becoming smaller every day, the field of molecular electronics has become ever more critical in solving the problem of further miniaturization,
The idea of creating a single-molecule diode was suggested by Arieh Aviram and Mark Ratner who theorized in 1974 that a molecule could act as a rectifier, a one-way conductor of electric current.
They have shown that single-molecules attached to metal electrodes (single-molecule junctions) can be made to act as a variety of circuit elements
including resistors, switches, transistors, and, indeed, diodes. They have learned that it is possible to see quantum mechanical effects, such as interference, manifest in the conductance properties of molecular junctions.
Since a diode acts as an electricity valve, its structure needs to be asymmetric so that electricity flowing in one direction experiences a different environment than electricity flowing in the other direction.
In order to develop a single-molecule diode, researchers have designed simply molecules that have asymmetric structures.""While such asymmetric molecules do indeed display some diode-like properties,
they are not effective, "explains Brian Capozzi, a Phd student working with Venkataraman and lead author of the paper."
"A well-designed diode should only allow current to flow in one direction-the'on'direction
-and it should allow a lot of current to flow in that direction. Asymmetric molecular designs have suffered typically from very low current flow in both'on and off'directions,
and used gold metal electrodes of different sizes to contact the molecule. Their results achieved rectification ratios as high as 250: 50 times higher than earlier designs.
including those that are made with graphene electrodes.""It's amazing to be able to design a molecular circuit,
An illustration of the molecule used by Columbia Engineering professor Latha Venkataraman to create the first single-molecule diode with a non-trivial rectification ratio overlaid on the raw current versus voltage data.
Diodes are fundamental building blocks of integrated circuits; they allow current to flow in only one direction.
#Researchers develop a semiconductor chip made almost entirely of wood Portable electronics-typically made of nonrenewable,
In an effort to alleviate the environmental burden of electronic devices, a team of University of Wisconsin-Madison researchers has collaborated with researchers in the Madison-based U s. Department of agriculture Forest Products Laboratory (FPL) to develop a surprising solution:
a semiconductor chip made almost entirely of wood. The research team, led by UW-Madison electrical
and computer engineering professor Zhenqiang"Jack"Ma, described the new device in a paper published May 26, 2015 by the journal Nature Communications("High-performance green flexible electronics based on biodegradable
or support layer, of a computer chip, with cellulose nanofibril (CNF), a flexible, biodegradable material made from wood."
"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,
"Now the chips are so safe you can put them in the forest and fungus will degrade it.
"Working with Shaoqin"Sarah"Gong, a UW-Madison professor of biomedical engineering, Cai's group addressed two key barriers to using wood-derived materials in an electronics setting:
CNF offers many benefits over current chip substrates, she says.""The advantage of CNF over other polymers is that it's a bio-based material and most other polymers are based petroleum polymers.
"The group's work also demonstrates a more environmentally friendly process that showed performance similar to existing chips.
The majority of today's wireless devices use gallium arsenide-based microwave chips due to their superior high-frequency operation and power handling capabilities.
However, gallium arsenide can be environmentally toxic, particularly in the massive quantities of discarded wireless electronics.
"I've made 1, 500 gallium arsenide transistors in a 5-by-6 millimeter chip. Typically for a microwave chip that size,
there are only eight to 40 transistors. The rest of the area is wasted just, "he says."
and make a completely functional circuit with performance comparable to existing chips.""While the biodegradability of these materials will have a positive impact on the environment,
Ma says the flexibility of the technology can lead to widespread adoption of these electronic chips."
"Mass-producing current semiconductor chips is so cheap, and it may take time for the industry to adapt to our design,
"But flexible electronics are the future, and we think we're going to be well ahead of the curve

what is now done with electric currents in semiconductor integrated circuits. Researchers have developed many approaches to do this, but have not yet been able to put the oldest and simplest artificial light sourcehe incandescent light bulbnto a chip.
This is primarily because light bulb filaments must be extremely hothousands of degrees Celsiusn order to glow in the visible range
