New composite material made of carbon nanotubes

Wed, 2017-11-22 22:00
Due to their unique properties, carbon nanotubes would be ideal for numerous applications, but to date they cannot be combined adequately with other materials, or they lose their beneficial properties. Scientists have developed an alternative method of combining, so they retain their characteristic properties. As such, they 'felt' the thread-like tubes into a stable 3-D network.

Nano-watch has steady hands

Tue, 2017-11-21 23:55
A new nanomechanical hand shows the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less than a thousandth of a millimetre long, can be trapped in thin air using focused laser beams, and spun to follow the ticking of a clock, losing only one-millionth of a second over four days.

Topological insulators: One glimpse is enough

Tue, 2017-11-21 22:53
The Nobel Prize for physics in 2016 was awarded for the theory of topological matter. Topological insulators are new materials with special electronic properties and are of great fundamental and applications-oriented interest. Nevertheless, physicists have wrestled with a ten-year-old puzzle in which the results from the two best methods to probe their electronic states disagree. Researchers now know exactly why.

Spin current from heat: New material increases efficiency

Mon, 2017-11-20 21:18
Electronic devices such as computers generate heat that mostly goes to waste. Physicists have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents'. In future, these signals could replace some of the electrical current in electronic components.

Underwater Sniffing of Star-Nosed Moles Is Mimicked for Chemical-Detecting ‘Electronic Nose’

Mon, 2017-11-20 19:30
The star-nosed mole has several unusual abilities. One of them is “sniffing” underwater by blowing bubbles and quickly re-inhaling them, detecting odors of its prey through the water. The moles’ “star” nose features a ring of tiny, pink tentacles and is the most sensitive known touch organ of any mammal.

Breakthrough could launch organic electronics beyond cell phone screens

Sat, 2017-11-18 05:37
A new discovery points the way to more widespread use of an advanced technology generally known as organic electronics.

Strain-free epitaxy of germanium film on mica

Sat, 2017-11-18 00:47
Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it's making a comeback. It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica.

New window into electron behavior

Fri, 2017-11-17 00:51
For the first time, physicists have developed a technique to visualize the behavior of electrons beneath a material's surface.

Math gets real in strong, lightweight structures

Thu, 2017-11-16 23:51
Materials scientists lead a project to turn strong, light and compressible schwarzites from theory to reality with three-dimensional printers. The resulting materials share their properties from the nano- to the macroscale.

Ionic 'solar cell' could provide on-demand water desalination

Wed, 2017-11-15 23:39
Modern solar cells, which use energy from light to generate electrons and holes that are then transported out of semiconducting materials, have existed for over 60 years. Little attention has been paid, however, to the promise of using light to drive the transport of oppositely charged protons and hydroxides obtained by dissociating water molecules. Researchers report such a design, which has promising application in producing electricity to turn brackish water drinkable.

Three-dimensional nanomagnets for the computer of tomorrow

Wed, 2017-11-15 23:16
Since the late 60's electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.

Pulling iron out of waste printer toner

Wed, 2017-11-15 22:20
Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment. A research group reports that they have devised a method to recycle the residual powder in 'empty' cartridges into iron using temperatures that are compatible with existing industrial processes.

Molecular magnetism packs power with 'messenger electron'

Tue, 2017-11-14 06:20
A UW-Madison lab has made a molecule that gains magnetic strength through an unusual way of controlling those spins, which could lead to a breakthrough in quantam computing.

When electronics, photonics meet on a standard chip

Fri, 2017-11-10 19:16
Electronics and light don't go well together on a standard 'CMOS' chip. Researchers have succeeded in introducing a light connection into the heart of a semiconductor chip. In this way, two circuits can communicate. Or: the worlds of electronics and photonics are connected.

The next generation of power electronics? Gallium nitride doped with beryllium

Thu, 2017-11-09 23:42
Physicists have made a breakthrough in revising methods largely discarded 15 years ago. They have discovered a microscopic mechanism that will allow gallium nitride semiconductors to be used in electronic devices that distribute large amounts of electric power.

Transfer technique produces wearable gallium nitride gas sensors

Thu, 2017-11-09 23:41
A transfer technique based on thin sacrificial layers of boron nitride could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The technique could facilitate the production of low-cost wearable, mobile and disposable sensing devices for a wide range of environmental applications.

Thu, 2017-11-09 01:07
Researchers have developed a way to make optically based microchips that can flex and bend like rubber and could be used for skin-mounted diagnostics or flexible strain sensors.

Fully integrated circuits printed directly onto fabric

Wed, 2017-11-08 20:52
Researchers have successfully incorporated washable, stretchable and breathable electronic circuits into fabric, opening up new possibilities for smart textiles and wearable electronics. The circuits were made with cheap, safe and environmentally friendly inks, and printed using conventional inkjet printing techniques.

Wed, 2017-11-08 19:52
Engineers have created sensors that can be printed onto plant leaves and reveal when the plants are experiencing a water shortage, which could give farmers an early warning when their crops are in danger.
