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.
Inspired by characteristics of polar bear fur, lotus leaves, and gecko feet, engineering researchers have developed a new way to make arrays of nanofibers that could lead to coatings that are sticky, repellant, or insulating, or could emit light.

Many materials exhibit new properties when in the form of thin films composed of just a few atomic layers. Most people are familiar with graphene, the two-dimensional form of graphite, but thin film versions of other materials also have the potential to facilitate technological breakthroughs. Researchers have shed light on the behavior of one of these ultrathin materials, called tin telluride.

Researchers have invented a roll-to-roll process to coat electrically conductive carbon fibers with semiconducting silicon carbide nanoparticles. When enough of this coated fiber is embedded in a polymer, the resulting composite is stronger than other fiber-reinforced composites and can monitor its own structural health.
