  2. SmartWater - Wikipedia

    en.wikipedia.org/wiki/SmartWater

    SmartWater is a clear, water-based liquid containing an identifying code that can be viewed under ultraviolet light. [6] It is intended to be applied to valuable items, including equipment at construction sites, merchandise in retail stores, and vacant residential or commercial properties. [7]

  3. Ultraviolet index - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_index

    The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface. It cannot be simply related to the irradiance (measured in W / m 2 ) because the UV of greatest concern occupies a spectrum of wavelengths from 295 to 325 nm, and shorter wavelengths have already been absorbed a ...

  4. UV coloration in flowers - Wikipedia

    en.wikipedia.org/wiki/UV_coloration_in_flowers

    The pollen grains reflect UV-beta to shield their chromosomes stored in the pollen from UV-alpha which is important for making sure of reproductive success. [10] The technique of UV coloration has evolved in other species as well for various reasons. Similarly, carnivorous plants reflect and absorb UV to attract prey to it. [10]

  5. Gloeocapsin - Wikipedia

    en.wikipedia.org/wiki/Gloeocapsin

    Gloeocapsin is an extracellular pigment of some cyanobacteria, believed to provide UV-protection to the cell. [1] [2] It is especially abundant in cyanobacterial species that inhabit places exposed to high levels of sunlight, such as the surface of rocks.

  6. Hindered amine light stabilizers - Wikipedia

    en.wikipedia.org/wiki/Hindered_amine_light...

    Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.

  7. UV detectors - Wikipedia

    en.wikipedia.org/wiki/UV_detectors

    Diode array detectors (DADs) collect entire UV spectra at every point of the eluting peaks while operating as a multi-wavelength UV-Vis detector. This way they give additional information, which help understand more about the nature of the substances appearing in the chromatogram and allow their identification. [6]
