Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% [4] in the visible spectrum. The name is a portmanteau of the acronym VANTA ( vertically aligned nanotube arrays ) [ 5 ] and black .
As a result, infrared light of a wavelength longer than a few micrometers penetrates through the dark layer and has much higher reflectivity. The reported spectral dependence increases from about 1% at 3 μm to 50% at 20 μm. [3] In 2009, a competitor to the super black material, Vantablack, was developed based on carbon nanotubes. It has a ...
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.
Here’s what you need to know. What is black salve? Black salve is a real concoction that’s been called “dangerous” by the Food and Drug Administration (FDA). The ointment is considered a ...
[1] In color theory, a shade is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. In practice, many off-black colors possess a hue and a colorfulness (also called saturation).
