A theoretically pure and defect-free diamond would be completely colorless, and a unique attribute would be its transparency (or lack of light absorption) across a wide portion of the electromagnetic ...

We test the relationship between canopy photosynthesis and reflected near-infrared radiation from vegetation across a range of functional (photosynthetic pathway and capacity) and structural ...

As well as enabling wearers to perceive more detail within the infrared spectrum, these color-coding nanoparticles might be modified to help color blind people see wavelengths that they would ...

Thus, a novel fault diagnosis method based on spectrum transition entropy (SpTE) is proposed. First, a symbolization method is constructed to represent the time-frequency distribution (TFD) of signals ...

As well as extending our ability to perceive more of the infrared spectrum, another potential use here could be correcting color-blind vision. This is because the lenses can be made to color code ...

In a previous study, researchers at the University of Science and Technology of China demonstrated how injecting nanoparticles into the retinas of mice allowed them to see in the near-infrared ...

though infrared vision was enhanced when participants had their eyes closed. An additional tweak to the contact lenses allows users to differentiate between different spectra of infrared light by ...

In typical human-centric fashion, we call that the 'visible' part of the spectrum, even though other animals can see beyond it. In a new study, scientists have helped humans catch a glimpse of light ...

The upconverting nanoparticles absorb multiple low-energy infrared photons, each invisible on its own, and combine their energy to emit a single, higher-energy photon in the visible spectrum.
