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 ...

Current data suggest that anticoagulation with warfarin or dabigatran is far superior to aspirin in the prevention of stroke or systemic embolism in AF. There is no dispute on the recommendations ...

To try to better characterize the nature of this missing C, we have compared the bulk infrared (IR) absorption spectra of a number of primitive chondrites with those of their previously reported ...

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 ...

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.
