Detail photo of the positioning of a small glass tube filled with argon gas that contains a twisted nanocarbon across from a high-resolution micro lens, which will be used to monitor the local temperature of the small filaments in an experiment in the Kotov Lab at the North Campus Research Center of the University of Michigan in Ann Arbor on Wednesday, December 18, 2024. This lens and the software used with it allowed for precise thermal mapping of the twisted nanocarbon. The glass tube is filled with argon because nanocarbon is highly susceptible to oxidation under air conditions, especially when heated. Argon, being an inert gas, prevents oxidation and ensures the stability of the nanocarbon during high-temperature operation.
Researchers from the Kotov Lab have found that submicrometer twisted filaments made from materials like nanocarbon or metals can produce strong chiral infrared photons, especially in the wavelength range of 500 to 300 nanometers. The twisted filaments emit light that is significantly brighter, up to 100 times more bright than other similar light emitters. The special helical shape of the filaments helps in controlling the type of twisted light they emit. Additionally, coating these nanocarbons with durable, transparent ceramics results in bright and adjustable chiral emitters capable of functioning at temperatures that were previously thought to be unreachable. This advancement opens new possibilities in the field of chiral photonics and high-temperature applications. COMPASS is the Center for Complex Particle Systems which is directed by Nicholas Kotov, the Irving Langmuir Distinguished University Professor of Chemical Sciences and Engineering.

I like how this crab spider is color coordinated. I looked up what it might be and found "a highly variable White Banded Crab Spider, Misumenoides formosipes, and it is harmless". (At least to humans) Not sure if I'm right, but it looks like it.
