Scientists print nanoscale imaging probe onto tip of optical fiber

A team of researchers has developed a way to print a nanoscale imaging probe onto the tip of a glass fiber as thin as a human hair, accelerating the production of the promising new device from several per month to several per day. The high-throughput fabrication technique opens the door for the widespread adoption of this and other nano-optical structures, which squeeze and manipulate light in ways that are unachievable by conventional optics.

Water-repellant material sheds like a snake when damaged

Imagine a raincoat that heals a scratch by shedding the part of the outer layer that’s damaged. To create such a material, scientists have turned to nature for inspiration. They report a water-repellant material that molts like a snake’s skin when damaged to reveal another hydrophobic layer beneath it.

Stenciling with atoms in 2-dimensional materials possible

The possibilities for the new field of two-dimensional, one-atomic-layer-thick materials, including but not limited to graphene, appear almost limitless. In new research, material scientists report two discoveries that will provide a simple and effective way to ‘stencil’ high-quality 2-D materials in precise locations and overcome a barrier to their use in next-generation electronics.
