Vantablack has also sparked interest from the scientific community for use in cameras and sensors. Its distinctive characteristics make it a desirable material for cinema projectors, lenses, luxury products, and design items. Furthermore, its light-absorbing properties have the potential to improve the efficiency of solar panels and cells. [30]
A fine book shows no damage. Very good (VG) describes a book that is worn but untorn. For many collectors this is the minimum acceptable condition for all but the rarest items. Any defects must be noted. Good (G) describes the condition of an average used worn book that is complete. Any defects must be noted.
Rich black is often regarded as a color that is "blacker than black". While this is impossible from the point of view of color theory, the difference can often be seen in the printed piece. The difference is most apparent in backlit (also known as "translite") pieces, where rich black more thoroughly blocks the light from coming through.
A fact from Vantablack appeared on Wikipedia's Main Page in the Did you know column on 20 July 2014 (check views). The text of the entry was as follows: The text of the entry was as follows: Did you know ... that Vantablack , a material made from carbon nanotubes , is the blackest substance known?
The capacitance of the SWNT solid EDLC was estimated as 20 F g −1 from the discharge curves of cells charged at 2.5V for a two-electrode cell, and corresponds to 80 F g −1 for a three-electrode cell. The energy density (W = CV 2 /2) was estimated to be 69.4 W h kg −1 (from 80 F g −1) when normalized to the single electrode weight.
Overprinting refers to the process of printing one colour on top of another in reprographics.This is closely linked to the reprographic technique of 'trapping'.Another use of overprinting is to create a rich black (often regarded as a colour that is "blacker than black") by printing black over another dark colour.
The color displayed at right matches the color sample called taupe referenced below in the 1930 book A Dictionary of Color, the world standard for color terms before the invention of computers. However, the word taupe is currently often used to refer to lighter shades of taupe, and therefore another name for this color is dark taupe.
