Stars in the visible-light images are between 1 million and several billion years old; the youngest stars, those between 1 million and 100 million years old, shine prominently in ultraviolet light
Although our eyes have three color receptors, one of which is blue sensitive, we have no mechanism to see ultraviolet light
because this blue-light receptor has only a very slight sensitivity to near-ultraviolet light.
Irresistible Materials is in the final stages of testing a new photo-resist coating which will enable chip manufacturers to meet a new industry standard related to the width of the ultraviolet light
With its vibrating base plate Bed Vac starts by loose, then zaps them with ultraviolet light
killing them to feed.
is energetic enough to break chemical bonds, which is exactly what it does to a photoinitiator that is incorporated into the mix.
(A) All creatures glow under ultraviolet light
, and now scientists have discovered why.
Even when the ultraviolet light
was turned off, the animals stayed stunned.
(See last photo on page 12.) Once this is done, the LED will glow with a violet and ultraviolet light
. While you can see the violet light, you won't be able to see the ultraviolet light
Irradiation with ultraviolet light
is gaining attention as an alternative to chemicals and thermal treatments for sterilizing food products that can be marketed to consumers as natural and safe.
VITAL CLUE SmartWater, pictured under ultraviolet light
, is almost impossible to remove.
Extracted apple juice was treated with ultraviolet light
(14 mJ per [cm.sup.2]), microfiltration (0.45[micro]m) and pasteurization (71 C for 6 seconds and 85 C for 60 seconds) to eliminate unwanted microorganisms prior to the fermentation process.
They hope the changeover will revive a detector that collects ultraviolet light
