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]
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 ...

MM2 may refer to: MM2, a class of force fields; see force field (chemistry) MM2 (MMS), an interface utilized by the Multimedia Messaging Service standard; Mega Man 2, a 1988 video game for the NES; Mega Man II, a 1991 video game for the Game Boy; Midtown Madness 2, a 2000 video game for the PC; Motocross Madness 2, a 2000 video game for the PC
For example, the point groups 1, 2, and m contain different geometric symmetry operations, (inversion, rotation, and reflection, respectively) but all share the structure of the cyclic group C 2. All isomorphic groups are of the same order , but not all groups of the same order are isomorphic.
