The multifunctional asymmetric bilayer MXene-graphene oxide (MG)-MXene aerogel with ultrahigh absorption electromagnetic interference (EMI) shielding is constructed by 3D printing and subsequent ...
(Nanowerk News) Professor Yeom’s research team (Department of Materials Science and Engineering, KAIST) developed chiral ceramic nanostructures with broad chiroptical activity through a self-assembly ...
A theory from 2006 predicts that it should be possible to use graphene in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular ...
BUFFALO, N.Y. — A team from the University of Buffalo has developed an organic material which is capable of absorbing three photons at infrared (IR) wavelengths and re-emitting the light in the ...
A thermochromic film embedded with size-optimized microcapsules autonomously switches between passive heating and cooling ...
Imec, the nanoelectronics and digital technologies research hub, has announced the successful integration of a pinned photodiode structure into thin-film image sensors. With the addition of a ...
Speaker one Minus 273 degrees Celsius is the lowest possible temperature. It’s called absolute zero. Any object with a temperature above this will emit and absorb infrared radiation, even the Earth.
