SILKWORMS SPIN SUPER-STRONG SILK AFTER EATING GRAPHENE

BY ANTHONY CUTHBERTSON ON 10/10/16 AT 6:13 AM

Carbon-reinforced silk that is twice as strong as regular silk has been created by feeding the “wonder material” graphene to silkworms.

Scientists at Tsinghua University in Beijing, China, fed the silkworms mulberry leaves coated in a solution that contained graphene in order to create the material. Applications for the material created include wearable electronics, durable fabrics and biodegradable medical implants.

“Silkworm silk is gaining significant attention from both the textile industry and research society because of its outstanding mechanical properties and lustrous appearance,” states a paper describing the research published in the journal Nano Letters. “The possibility of creating tougher silks attracts particular research interest.

“We report mechanically enhanced silk directly collected by feeding…silkworms with single-walled carbon nanotubes and graphene. We found that parts of the fed carbon nanomaterials were incorporated into the as-spun silk fibers.”

According to scientists not involved in the most recent research, the results suggest that production of the super-strong material could be scaled up. Materials scientist Yaopeng Zhang of Donghua University said that the method provided an “easy way to produce high-strength silk fibers on a large scale,” according to Chemical and Engineering News.

Graphene, first created in a laboratory by researchers at the University of Manchester in 2004, has been heralded for its remarkable properties and vast potential. The one-atom thick material consists of carbon atoms in a honeycomb lattice that is 200-times stronger than steel, more conductive than copper and as flexible as rubber.

These properties could potentially be used to create everything fromindoor solar cells to “tattoos” capable of testing and treating diabetics.

“For many years people have been looking for graphene applications that will make it into mainstream use,” Professor Ravi Silva, a graphene researcher at the University of Surrey, told Newsweek in an interview earlier this year. “We are finally now getting to the point where these applications are going to happen.”

Silkworms get Spiderman-like strength: Insects fed with graphene produce strong fibres that conduct electricity
  • Researchers fed silkworms small amounts of carbon nanomaterials
  • They found the caterpillars incorporated the materials into a 'super silk'
  • The reinforced fibres were far tougher and more conductive than normal
  • They believe the approach could be used be used for large-scale production of silks with added strength and new properties

Legend puts the discovery of silk down to an empress thousands of years ago, who unravelled the fine threads after the cocoon of a silkworm fell in her tea.

But the luxury thread, prized for its strength, light weight and versatility, has now been given new properties, thanks to the work of Chinese scientists.

By feeding silkworms carbon nanotubes and graphene, researchers enabled the insects to spin ‘super silk’ – far tougher, more durable and conductive than normal threads – opening up new possibilities for fabrics, medical implants and more.

REINFORCED SUPER SILK

Silkworms fed graphene produced super silk which was far stronger than normal silk and conducted electricity after heating to high temperatures.

A team in China fed the insects just 0.2 per cent nanomaterials by total weight of their food.

They believe the approach could be used be used for large-scale production of silks with added strength and new properties.

Silk is produced by the caterpillars of the silk moth, as they feed on the leaves of mulberry trees.

When ready, the larvae cocoon themselves in a tangle of the fibre – produced from proteins in their salivary glands – while transforming into the adult moths.

Textile manufacturers frequently tweak the properties of silk fibres, adding dyes and antimicrobial compounds to them.

But a team at Tsinghua University found that feeding the larvae a diet fortified with nanomaterials, including graphene and carbon nanotubes, enabled the larvae to reinforce the threads themselves.

Parts of the nanomaterials were incorporated into the fibres spun by the insects.

But a team at Tsinghua University found that feeding the larvae a diet fortified with nanomaterials, including graphene and carbon nanotubes, enabled the larvae to reinforce the threads themselves.

According to Scientific American, the reinforced silk is far stronger and able to withstand 50 per cent more stress before the strands break.

What’s more, they found that after heating the fibres to high temperatures, the threads were able to conduct electric currents far better and had a more ordered crystal structure.

The amount of carbon nanomaterials fed to the insects is tiny, just 0.2 per cent by weight of their food and avoids the need to dissolve the carbon components in toxic solvents, as would be needed to treat normal silk.

It is unclear exactly how the silk is incorporated into the silk, or how much needs to be fed to the caterpillars in order to make it into the thread – that the animals don’t use themselves or excrete as a waste product.

But the team, led by Yingying Zhang, say the threads could potentially be used for sensors embedded in smart sensors or even medical implants.

Writing in the journal Nano Letters, the team explains: ‘The successful generation of these [silks] by…feeding is expected to open up possibilities for the large-scale production of high-strength silk fibers.’

WHAT IS GRAPHENE?

Graphene is a single atomic layer of carbon atoms bound in a hexagonal network.

It not only promises to revolutionize semiconductor, sensor, and display technology, but could also lead to breakthroughs in fundamental quantum physics research.

It is often depicted as an atomic-scale chicken wire made of carbon atoms and their bonds.

Scientists believe it could one day be used to make transparent conducting materials, biomedical sensors and even extremely light, yet strong, aircraft of the future.

Similar to another important nanomaterial - carbon nanotubes - graphene is incredibly strong - around 200 times stronger than structural steel.

Huawei unveils breakthrough graphene-assisted Li-ion battery

huawei-logo-mwc-2015-4-840x473.jpg


Watt Laboratory, an organization under Huawei’s Central Research Institute, has introduced a new graphene-assisted Li-ion battery which can withstand higher temperatures when compared with ordinary Li-ion batteries.

The new batteries are able to function at a temperature of 60°C (140℉), which is 10°C (50℉) above the current upper limit. They can be used in cellular base stations in high-temperature regions around the world and have a lifespan that is twice as long as ordinary Li-ion batteries.

In addition, the new batteries can extend the range of EVs in high temperatures and can also be used in drones, which tend to produce quite a bit of heat.

Dr. Yangxing Li, Chief Scientist at Watt Laboratory, has stated that there are three technologies that have assisted them in making a breakthrough in this battery technology. The first is a special additive in the electrolytes that can remove trace water and prevent the electrolytes from evaporating in high temperatures.

The second is modified large-crystal NMC materials that are used for the cathode and are able to improve the thermal stability of the cathode powder, while the third is graphene, which allows for more efficient cooling of the Li-ion battery.

Dr. Yangxing Li also said that charging and discharging tests in a high-temperature environment have shown that the graphene-assisted high-temperature Li-ion battery is 5°C (41℉) cooler than ordinary Li-ion batteries. And after being recharged 2,000 times at a temperature of 60°C (140℉), the graphene battery retains more than 70 percent of its capacity.

In other battery-related news, Huawei’s Watt Laboratory introduced a quick charging technology back in 2015, which is able to charge 48 percent of a 3,000 mAh battery in only 5 minutes. The company has now said that that technology will soon be available. Huawei plans on announcing a new smartphone in late December that will have the new quick battery charging tech onboard.

There is no other information regarding the device for now, so we’ll just have to wait for a month or so to see what Huawei will bring to the table. Stay tuned.

Huawei unveiled the world's first long-lifespan graphene-assisted high temperature Li-ion batteries,which allow Li-ion batteries to remain functional in a 60°C environment, a temperature 10°C higher than the existing upper limit. These new batteries lifespan will also be twice as long as ordinary ones. This technology breakthrough will allow base stations to be rapidly deployed without air-conditioning, and also pave the way for potential high temperature applications for drones and electric vehicles.
