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 ...
CVD Vantablack was an improvement over similar substances developed at the time. Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F). NASA had previously developed a similar substance that was grown at 750 °C (1,380 °F), which required materials to be more heat resistant than Vantablack. [24]
Oxidants can not only remove or prevent amorphous carbon growth, but may also etch into graphite layers when used at higher than favorable concentrations. Hata et al. reported millimeter-scale vertically aligned 2.5 mm long SWCNTs using the water assisted ethylene CVD process with Fe/Al or aluminum oxide multilayers on Si wafers. [17]
The sentence "Vantablack was an improvement over similar substances developed at the time." seems a bit odd, as no points of time have yet been mentioned at this point in the article. Maybe it should say something like "Vantablack is an improvement over similar substances developed before it"? JoaCHIP 10:39, 8 June 2019 (UTC)
It really shows the difference between the two animals. In the video, Peppa, the miniature Jack Russell Terrier, definitely has energy for days.She was running so fast, we're surprised she didn't ...
Trump’s plan to eliminate taxes on Social Security benefits would help current beneficiaries, but future recipients may be hurt by the move.
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.
In his new Netflix comedy special “What Had Happened Was,” Jamie Foxx finally told the story behind the mysterious and harrowing medical emergency that left him hospitalized and fighting for ...
