When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. [24] 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).
There are two primary growth models for the CVD growth of VANTAs: “tip-growth model” and the “base-growth model.” [2] In the case of the tip-growth model, hydrocarbon decomposes on the top surface of the metal, carbon diffuses down through the metal, and CNT precipitates out across the metal bottom, pushing the whole metal particle off ...
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 ...
Vantablack is an extremely black chemical substance. Vantablack may also refer to: Vantablack, a 2017 dubstep extended play by Dirtyphonics and Sullivan King "Vantablack", a 2017 song by French synthwave musician Perturbator "Vantablack", a 2022 episode of Fleishman Is in Trouble
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)
Platinum black (Pt black) is a fine powder of platinum with good catalytic properties. The name of platinum black is due to its black color. It is used in many ways; as a thin film electrode, a fuel cell membrane catalyst, or as a catalytic ignition of flammable gases for "self-lighting' gas lamps, ovens, and stove burners.
The measurement of sales of popular music starts high relative to the wedding anniversary scale, concentrating on gold and platinum (see gold album).Likewise, credit card companies usually have a "gold card" and a "platinum card" (many formerly had a "silver card" then followed by a "gold card", but due to similarity in appearance between silver and platinum these were often discontinued with ...
