KIST researchers have developed a material that has properties similar to graphene but is ...

For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.  Read More

Researchers have increased the toughness of various metals by giving them a 'gradient stru...

Steel is a common benchmark against which the strength of materials is measured, with "stronger than steel" a familiar catch cry for those touting the properties of some new space-age material. But now researchers at North Carolina State University have created steel that is stronger than steel using a process that increases the toughness of various metals by altering the microstructures within them.  Read More

In its low-drag configuration, the 'smorph' looks like a golf ball (Image: MIT)

Researchers at MIT have developed a smart curved surface that can morph at will to reduce drag, generating a series of small, evenly spaced dimples that make it resemble the outside of a golf ball. This technology could be used to reduce hurricane damage on some public buildings, as well as increase the aerodynamic and fuel efficiency in cars.  Read More

The underside of the reinforced concrete beam has been fitted with two iron-based SMA stri...

Shape memory alloys (SMAs), which when heated are able to return to their original shape after being severely deformed, have found their way into everything from spectacle frames to cars. Now researchers at Empa in Switzerland have developed a new type of SMA that could allow the material to find applications in the building and construction industries.  Read More

Lawrence Livermore Engineer Xiaoyu 'Rayne' Zheng studies a macroscale version of the unit ...

Imagine materials strong enough to use in building airplanes or motor cars, yet are literally lighter than air. Soon, that may not be so hard to do because a team of researchers from MIT and Lawrence Livermore National Laboratory (LLNL) have developed new ultra-lightweight materials that are as light as aerogel, but 10,000 times stiffer, and may one day revolutionize aerospace and automotive designs.  Read More

Can garbage be used as an eco-material to construct a house? That's the intriguing premise behind the recently-completed Waste House project, which is believed by those involved to be the first permanent British building built almost solely from waste and recycled materials. Constructed at the University of Brighton's Grand Parade campus, the Waste House is an ongoing experiment which aims to prove, in the organizer's own words, that "there is no such thing as waste, just stuff in the wrong place."  Read More

Raydiance's R-Cut femtosecond laser system allows for mobile phones with complex shapes

Smartphones have come a long way in a few short years, but two things have remained constant; most sport a "slab of glass" form factor, and dropping one makes you wish you’d had it insured. Designers have used new materials, such as Gorilla glass and sapphire to make phone displays lighter and more durable, but these have introduced their own problems – especially when it comes to manufacturing. Gizmag spoke with Raydiance, a company specializing in cutting-edge laser fabrication methods, about its new R-Cut femtosecond laser system that promises a “new paradigm" in high-tech glass fabrication.  Read More

The flexible supercapacitor composed of graphene and carbon nanotubes (Photo: Dr.Dingshan ...

An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.  Read More

A regenerative plastic developed at the University of Illinois seals up more than cracks

Dropping your mobile phone can ruin your whole day as you look down at the spiderweb of cracks surrounding a small hole in the once-pristine plastic case. Now imagine watching as those cracks and that hole seal up by themselves, leaving behind a completely healed case. That may sound like science fiction, but it may not be for long with a team of researchers at the University of Illinois having developed a new system that doesn't just repair minor cracks in plastic, but regenerates to heal large holes.  Read More

Scientists at Los Alamos National Laboratory (LANL) in the US have confirmed a 7.68 oz (217.78 g) piece of gold is in fact a singular crystal, increasing its value from around US$10,000 to an estimated $1.5 million. The specimen, the largest single crystal piece of gold in the world, was discovered in Venezuela decades ago, but it is only by using advanced probing instruments that experts can now verify its authenticity.  Read More
