• Twisting light: Novel metasurface offers compact solution for circularly polarized light
  Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from enhancing medical imaging techniques to enabling advanced communication technologies. However, generating circularly polarized light often requires complex and bulky optical set-ups, which hinders its […]
• Redefining the second: Optical atomic clock achieves record accuracy in comparison measurement
  The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at present. These optical clocks are still being assessed, but already now, some are 100 times more accurate than cesium clocks. They will […]

• New chainmail-like material could be the future of armor
  January 16, 2025
  Resembling the interlocking links in chainmail, novel nanoscale material is incredibly strong and flexible. The interlocked material contains 100 trillion mechanical bonds per 1 square centimeter — the highest density of mechanical bonds ever achieved. Small amounts of the mechanically interlocked polymer added to Ultem fibers increased the high-performance material's toughness.

Remember this annoying color change when you look at your screen at different angles? Professor So group at NCSU Materials Science and Engineering department offers a solution. The article is published in The Journal of the Society for Information Display (https://doi.org/10.1002/jsid.792)

The power has been restored. All IMAKS instruments are up and running. Good luck with your experiments.

All power will be down on NCSU Centennial campus starting at 7:30 a.m. on Sunday, June 2 . The crews will connect power lines to newly constructed buildings. As a result, all instruments have to be powered down and unplugged from wall outlets.

The facilities were planning to do work on secondary power lines (emergency lights, signs, and such). Accidentally, this morning they switched off the HVAC system and lab hoods. As a result, the lab got hot beyond the operating range of ultrafast lasers. facilities have been contacted. The temperature is getting to normal now. We anticipate we can start running experiments around 11 a.m.
