Fiber-optic probe can see molecular bonds

ScienceDaily.com: Nanotechnology News - Mon, 06/10/2019 - 19:15
Engineers have developed the world's first portable, inexpensive, optical nanoscopy tool that integrates a glass optical fiber with a silver nanowire condenser. The device is a high-efficiency round-trip light tunnel that squeezes visible light to the very tip of the condenser to interact with molecules locally and send back information that can decipher and visualize the elusive nanoworld.

Thwarting oil-pipeline corrosion by identifying a nanoscale villain

ScienceDaily.com: Nanotechnology News - Thu, 06/06/2019 - 21:37
Certain molecules of iron, when juxtaposed, have been found by researchers to cause microscopic holes in steel pipe used for oil transport. This hidden, localized corrosion causes oil pipes to rust unpredictably at rates faster than baselined, interfering with the accuracy of computer models that determine pipe replacement schedules. This problem, which is potentially environmental, may be addressed by changing the microstructure of the steel surface during forging.
