Imaging the spot of UV light produced by a “bow tie” nano-antenna
The intense light measures less than 70nm in diameter, far below the resolution of an optical microscope set by the diffraction limit.

New roles for two common materials
The goal is to improve the strength and mechanical stability of alumina while promoting the orderly distribution of pores on its surface.

A material concern for energy
From solar, wind and nuclear to coal, oil and natural gas, says John DuPont, the solutions to the world’s growing demand for energy share a common requirement — a sound understanding of the principles that underlie the joining of materials.
