Graphene

Monash University researchers have created a compact electrode that uses a liquid electrol...

Graphene-based supercapacitors have already proven the equal of conventional supercapacitors – in the lab. But now researchers at Melbourne’s Monash University claim to have developed of a new scalable and cost-effective technique to engineer graphene-based supercapacitors that brings them a step closer to commercial development.  Read More

Graphene continues to strengthen its reputation as a wonder material, this time in the fie...

Researchers from the Universities of Bath and Exeter have shown that a few layers of graphene stacked on top of each other could act as a formidable material for optical switches, delivering speeds up to 100 times faster than current telecommunications technology.  Read More

Researchers have found that a layer of graphene can keep electronic component hotspots up ...

For a two-dimensional material, graphene is certainly punching above its weight in terms of potential applications. Already set to enable faster, stronger and foldable electronic devices, researchers claim that the single layer lattice of carbon atoms can also help keep electronic components up to 25 percent cooler, giving it the potential to significantly extend the working life of computers and other electronic devices.  Read More

Columbia University researchers have come up with a way to produce large joined sheets of ...

A study conducted at Columbia University has revealed that even when stitched together from much smaller fragments, large sheets of graphene still retain much of their mechanical properties. The discovery may be a crucial step forward in the mass-production of carbon nanotubes that could be used to manufacture flexible electronics, ultra-light and strong materials, and perhaps even the first space elevator.  Read More

Assistant Professor Wang Qijie from NTU’s School of Electrical & Electronic Engineering (P...

A team of scientists at Nanyang Technological University (NTU) in Singapore has developed a new image sensor from graphene that promises to improve the quality of images captured in low light conditions. In tests, NTU claims it has proved to be 1,000 times more sensitive to light than existing complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD) camera sensors in addition to operating at much lower voltages, consequently using 10 times less energy.  Read More

A finger on the hydrogel hand bends in response to near-infrared laser light

For many people, the word “robot” is likely to conjure up images of metal, mechanical men not unlike Cygan. But instead of creating robots in our own image, the relatively new field of “soft robotics” takes inspiration from creatures such as octopuses, squids, starfish and caterpillars for soft, flexible robots that could squeeze through small spaces. Such robots could benefit from a new hydrogel developed at the University of California, Berkeley that flexes in response to light.  Read More

The new electrodes are made from a film consisting of graphene and silver nanowires (Image...

Transparent electrodes are in and of themselves nothing all that new – they’re currently used in things like touchscreens and flat-screen TVs. Thanks to research being conducted at Indiana’s Purdue University, however, a new class of such electrodes may soon find use in a variety of other applications, including flexible electronic devices.  Read More

Scientist have created inkjet-printable graphene-based ink, that could be used to create e...

While we hear a lot about flexible electronics that can be gently bent, how about ones that could actually be folded up? Things like the recently-developed graphite-based paper circuits definitely show promise, but now researchers from Illinois-based Northwestern University have taken another step forward – they’ve created graphene-based inkjet-printable ink.  Read More

A chunk of germanium in its natural form (Photo: Gibe)

It consists of one-atom-thick sheets and it could revolutionize electronics ... but it’s not graphene. Chemists at Ohio State University, instead of creating graphene from carbon atoms, have used sheets of germanium atoms to create a substance known as germanane. Because of its numerous advantages over silicon, it could become the material of choice for semiconductors.  Read More

The graphene aerogel can be supported by blades of grass

Not even a year after it claimed the title of the world’s lightest material, aerographite has been knocked off its crown by a new aerogel made from graphene. Created by a research team from China’s Zhejiang University in the Department of Polymer Science and Engineering lab headed by Professor Gao Chao, the ultra-light aerogel has a density lower than that of helium and just twice that of hydrogen.  Read More
