A lint roller for superclean graphene

NanoWerk.com - Thu, 09/26/2019 - 13:26
Researchers demonstrate that the amorphous carbon contaminants on CVD-produced graphene, which could greatly degrade its properties, can be removed by an activated carbon-coated lint roller, relying on the strong interactions between the amorphous carbon and activated carbon. Large-area graphene surfaces treated with this lint roller exhibit a high cleanliness of 99% with a low degree of polymer residue after transfer onto a functional substrate. This superclean graphene has extremely low contact resistance and ultrahigh carrier mobility.

Mosquito eye inspires artificial compound lens

ScienceDaily.com: Nanotechnology News - Wed, 09/25/2019 - 19:51
Anyone who's tried to swat a pesky mosquito knows how quickly the insects can evade a hand or fly swatter. The pests' compound eyes, which provide a wide field of view, are largely responsible for these lightning-fast actions. Now, researchers have developed compound lenses inspired by the mosquito eye that could someday find applications in autonomous vehicles, robots or medical devices.

Inspired by nacre, epoxy-graphene layered nanocomposites are tough and self-monitoring

NanoWerk.com - Wed, 09/25/2019 - 17:53
To make epoxy-graphene nanocomposites, the graphene nanosheets are commonly mixed homogeneously with the epoxy matrix. However, one of the problems that bedevils these nanocomposites is the issue of agglomeration of the nanofillers. Researchers now report that they have sucessfully tackled this dispersion problem by constructing a continuous graphene-based scaffold. The results show that the team's novel strategy boosts the fracture toughness to about 3.6 times that of pure epoxy.

Plastic teabags release microscopic particles into tea

ScienceDaily.com: Nanotechnology News - Wed, 09/25/2019 - 16:38
Many people are trying to reduce their plastic use, but some tea manufacturers are moving in the opposite direction: replacing traditional paper teabags with plastic ones. Now, researchers have discovered that a soothing cup of the brewed beverage may come with a dose of micro- and nano-sized plastics shed from the bags. Possible health effects of ingesting these particles are currently unknown, the researchers say.

Engineered protein crystals make cells magnetic

ScienceDaily.com: Nanotechnology News - Wed, 09/25/2019 - 16:38
If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside them have resulted in only weak magnetic forces. Now, researchers have engineered genetically encoded protein crystals that can generate magnetic forces many times stronger than those already reported.
