GE advises Korea to speed up innovation

Incheon South Korea

U.S. tech giant General Electric on Wednesday called for Korea to speed up its innovation to keep up with rapidly changing global trends that could make the country “easily left out.”

The company suggested that Korean society and businesses adopt “industrial Internet,” “advanced manufacturing” and a “global brain” to achieve stronger homegrown innovation, wider collaboration and education to become leaders in high-value industries.

Korean Research Team Develops One Atom Thick Semiconductor

A local research team has successfully developed a technique to make the thinnest semiconductor possible.

The National Research Foundation announced on June 25 that Professor Ahn Jong-ryeol and Ph.D. student Shin Ha-cheol at Sungkyunkwan University succeeded in developing a technique for a 0.25 nm semiconductor. The width is the minimum limit for making nanomaterials, because ~0.25 nm is the diameter of one atom.

Local semiconductor companies are currently conducting studies to make 10 nm semiconductor devices, but this research team pushed the limits, since they thought that it would be possible to produce a semiconductor material just one atom thick.

Samsung doubles battery capacity

Samsung researchers have developed materials that double the power capacity of lithium-ion batteries.

Samsung Advanced Institute of Technology (SAIT) said the technology uses silicon cathode material coded with high-crystalline graphene to produce batteries with twice as much capacity as ordinary lithium-ion batteries.

The institute said the research result was published in the international science journal Nature Communication on Thursday.

Graphene beyond the hype | Chemistry World


The wonder material. It’s just one atom thick but 200 times stronger than steel; extremely conductive but see-through and flexible. Graphene has shot to fame since its discovery in 2004 by UK-based researchers Andre Geim and Konstantin Novoselov, for which the University of Manchester pair were awarded the 2010 Nobel prize in physics.

Graphene gets bright: World’s thinnest lightbulb developed

World's thinnest lightbulb -- graphene gets bright!

“We’ve created what is essentially the world’s thinnest light bulb,” says Hone, Wang Fon-Jen Professor of Mechanical Engineering at Columbia Engineering and co-author of the study. “This new type of ‘broadband’ light emitter can be integrated into chips and will pave the way towards the realization of atomically thin, flexible, and transparent displays, and graphene-based on-chip optical communications.”

Rays of Hope: Fringe Fusion Ventures Take Small Steps Toward Energy Leap

Fusion Reactor

Multibillion-dollar projects are slowly moving ahead on the nuclear fusion frontier, but less traditional efforts to harness the power that fuels the sun say they’re making progress as well.

In the most basic fusion reaction, molecules of hydrogen isotopes are smashed together under high temperature and pressure to create helium — with part of the hydrogen mass converted into energy, in accordance with E=mc² from Albert Einstein’s special theory of relativity. The energy payoff can be immense, as demonstrated by the sun’s glare or the blast of an H-bomb. But can the reaction be controlled on Earth?

Memory Alloy Made From Base And Transition Metals To Find Greater Use In Medical Field


A new alloy produced recently by engineers will soon be used widely in the medical field, BBC reportedd. The alloy proved to be the most resilient material on record, which “springs back into shape even after it is bent more than 10 million times.”

The alloy is made up of nickel, copper and titanium, which can be applied in several areas, aircraft parts, artificial heart valves and refrigerators, the BBC report added. As it is, shape memory alloys are the choice material for heart stents.

Graphene layer could quadruple rate of condensation heat transfer in generating plants

Graphene layer could quadruple rate of condensation heat transfer in generating plants

A team of researchers at MIT has developed a way of coating these condenser surfaces with a layer of graphene, just one atom thick, and found that this can improve the rate of heat transfer by a factor of four—and potentially even more than that, with further work. And unlike polymer coatings, the graphene coatings have proven to be highly durable in laboratory tests.

Ames Laboratory scientists create cheaper magnetic material for cars, wind turbines

Melting material in preparation for producing a new type of magnet
Melting material in preparation for producing a new type of magnet

Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy’s Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare-earth permanent magnets.

The new alloy—a potential replacement for high-performance permanent magnets found in automobile engines and wind turbines—eliminates the use of one of the scarcest and costliest rare earth elements, dysprosium, and instead uses cerium, the most abundant rare earth.

The result, an alloy of neodymium, iron and boron co-doped with cerium and cobalt, is a less expensive material with properties that are competitive with traditional sintered magnets containing dysprosium.

Researchers used 4D printing to create a valve that opens and contracts according to water temperature

While 3D printing technology has proven to be a revolutionary solution with wide-ranging technological applications, a number of research teams have already begun looking beyond 3D printing, to the realm of 4D printing technology. While a number of 4D printed successes have already been achieved, researchers from the University of Wollongong in Australia have now created something very remarkable: a 4D printed a valve that automatically opens and contracts when exposed to either water or to high temperatures.
