LG Chem cable batteries may reshape mobile designs

(Phys.org)—LG Chem says it has a cable-type lithium-ion battery that is so flexible it can be tied in knots and worn as a bracelet or woven into textiles. For mobile device designers, the eventual commercial production ...

A way to cause graphene to self-fold into 3-D shapes

(Phys.org)—A team of researchers with Johns Hopkins University and MIT has found a way to cause flat sheets of graphene to self-fold into 3-D geometric shapes. In their paper published on the open access site Science Advances, ...

Imperfect graphene renders 'electrical highways'

(Phys.org) —Just an atom thick, 200 times stronger than steel and a near-perfect conductor, graphene's future in electronics is all but certain. But to make this carbon supermaterial useful, it needs to be a semiconductor ...

Organic 2-D films could lead to better solar cells

(PhysOrg.com) -- Solar cells made from organic materials are inexpensive, lightweight and flexible, but their performance lags behind cells that contain silicon or other inorganic materials. Cornell chemist William Dichtel ...

Kinematics of stretched sheets

In a new study now published as a report and also illustrated as the online cover-page of Science Advances, Julien Chopin, Arshad Kudrolli, and a research team in Physics in the U.S. and Brazil showed how twisted hyper-elastic ...

Chemists invent shape-shifting nanomaterial

Chemists have developed a nanomaterial that they can trigger to shape shift—from flat sheets to tubes and back to sheets again—in a controllable fashion. The Journal of the American Chemical Society published a description ...

Nanotechnology may lead to more energy-efficient electronics

Carbon nanotubes and graphene consist of just a couple of layers of carbon atoms, but they are lighter than aluminium, stronger than steel and can bend like spring-coils. Physicist Niklas Lindahl at the University of Gothenburg, ...
