Researchers at the National Institute of Standards and Technology have conducted simulations suggesting that graphene, in addition to its many other useful features, can be modified with special pores to act as a tunable filter or strainer for ions (charged atoms) in a liquid.
Imagine a world where cell phones and laptops can be charged in a matter of minutes instead of hours, rolled up and stored in your pocket, or dropped without sustaining any damage. To make this world a reality, scientists have patented an idea to improve battery performance by introducing tapers into the polymer membrane electrolytes that allow the lithium ions inside the battery to travel back and forth faster.

Researchers have shown a way to use graphene oxide to add some backbone to hydrogel materials made from alginate, a natural material derived from seaweed that is currently used in a variety of biomedical applications.

Researchers have developed a single-layer surface of nanostructures that can correct chromatic aberrations (which cause lenses to focus different wavelengths of light in different spots) across the visible spectrum and can be incorporated into commercial optical systems, from simple lenses to high-end microscopes.

Physicists have found the first evidence of a two-dimensional material that can become a magnetic topological insulator even when it is not placed in a magnetic field.

Researchers have discovered how to extend the useful life of "superalloys" by thousands of hours. The discovery could improve materials performance for electrical generators and nuclear reactors.
