Bioresorbable electronic stent could provide feedback, therapy

May 27, 2015 10:39 am | by American Chemical Society | News | Comments

Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. Scientists report in ACS Nano a new kind of multi-tasking stent that could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.

Mission possible: This device will self-destruct when heated

May 21, 2015 3:06 pm | by Liz Ahlberg, Physical Sciences Editor, Univ. of Illinois, Urbana-Champaign | Videos | Comments

Where do electronics go when they die? Most devices are laid to eternal rest in landfills. But what if they just dissolved away, or broke down to their molecular components so that the material could be recycled? Univ. of Illinois researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing.

New options for spintronic devices

May 18, 2015 10:46 am | by Helmholtz-Zentrum Berlin | News | Comments

Scientists from Paris and Helmholtz-Zentrum Berlin have been able to switch ferromagnetic domains on and off with low voltage in a structure made of two different ferroic materials. The switching works slightly above room temperature. Their results, which are published online in Scientific Reports, might inspire future applications in low-power spintronics, for instance for fast and efficient data storage.

Things You Need to Know about Digital Oscilloscopes

May 18, 2015 9:42 am | by Lisa Clark, Product & Test Engineer | Articles | Comments

Oscilloscopes are a staple for any individual or firm involved with electronics and their functioning due to their versatility. An oscilloscope, also called a scope, is a type of electronic test equipment that allows signal voltages to be viewed, usually as a 2-D graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis).

The laser-induced graphene device benefits greatly when boron becomes part of the mix. The Rice lab of chemist James Tour uses commercial lasers to create thin, flexible supercapacitors by burning patterns into common polymers.

Controlling swarms of robots with a finger

May 13, 2015 8:05 am | by Jason Maderer, Georgia Institute of Technology | Videos | Comments

Using a smart tablet and a red beam of light, Georgia Institute of Technology researchers have created a system that allows people to control a fleet of robots with the swipe of a finger. A person taps the tablet to control where the beam of light appears on a floor. The swarm robots then roll toward the illumination, constantly communicating with each other and deciding how to evenly cover the lit area.

The cane also features GPS functionality to aid navigation.

Improving organic transistors that drive flexible, comfortable electronics

May 5, 2015 12:40 pm | by Janet Lathrop, Univ. of Massachusetts, Amherst | News | Comments

A revolution is coming in flexible electronic technologies as cheaper, more flexible, organic transistors come on the scene to replace expensive, rigid, silicone-based semiconductors, but not enough is known about how bending in these new thin-film electronic devices will affect their performance, say materials scientists at the Univ. of Massachusetts Amherst.

New chip architecture may provide foundation for quantum computer

May 5, 2015 11:25 am | by American Institute of Physics | News | Comments

Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could revolutionize chemistry, biology and material science, but the development of quantum computers has been limited by the ability to increase the number of quantum bits, or qubits, that encode, store and access large amounts of data.

A first for field-effect transistors

May 5, 2015 11:14 am | by Bonnie Davis, Office of Communications and External Relations, Wake Forest Univ. | News | Comments

Researchers from Wake Forest Univ. and the Univ. of Utah are the first to successfully fabricate halide organic-inorganic hybrid perovskite field-effect transistors and measure their electrical characteristics at room temperature. The team designed the structure of these field-effect transistors to achieve electrostatic gating of these materials and determine directly their electrical properties.

Channeling valleytronics in graphene

May 5, 2015 8:05 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

To the list of potential applications of graphene we can now add valleytronics, the coding of data in the wave-like motion of electrons as they speed through a conductor. Lawrence Berkeley National Laboratory researchers have discovered topologically protected 1-D electron conducting channels at the domain walls of bilayer graphene. These conducting channels are “valley polarized".

“Fingerprinting” chips to fight counterfeiting

May 1, 2015 7:37 am | by Rob Matheson, MIT News Office | News | Comments

It’s often said that no two human fingerprints are exactly alike. For that reason, police often use them as evidence to link suspects to crime scenes. The same goes for silicon chips: Manufacturing processes cause microscopic variations in chips that are unpredictable, permanent, and effectively impossible to clone.

Chemists cook up three-atom-thick electronic sheets

April 30, 2015 8:41 am | by Anne Ju, Cornell Univ. | News | Comments

Making thin films out of semiconducting materials is analogous to how ice grows on a windowpane: When the conditions are just right, the semiconductor grows in flat crystals that slowly fuse together, eventually forming a continuous film. This process of film deposition is common for traditional semiconductors like silicon or gallium arsenide, but Cornell Univ. scientists are pushing the limits for how thin they can go.

Putting a new spin on computing memory

April 22, 2015 11:23 am | by Britt Faulstick, Drexel Univ. | News | Comments

Ever since computers have been small enough to be fixtures on desks and laps, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data. Unfortunately, the same drawbacks and perils of the mechanical sketch board have been just as pervasive in computing.
