  2. Electronic properties of graphene - Wikipedia

    en.wikipedia.org/wiki/Electronic_properties_of...

    The electronic properties of graphene are significantly influenced by the supporting substrate. [59] [60] The Si(100)/H surface does not perturb graphene's electronic properties, whereas the interaction between it and the clean Si(100) surface changes its electronic states significantly. This effect results from the covalent bonding between C ...

  6. CMYK color model - Wikipedia

    en.wikipedia.org/wiki/CMYK_color_model

    To reproduce color, the CMYK color model codes for absorbing light rather than emitting it (as is assumed by RGB). The "K" component absorbs all wavelengths and is therefore achromatic. The cyan, magenta, and yellow components are used for color reproduction and they may be viewed as the inverse of RGB.

  7. Graph coloring - Wikipedia

    Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable. For the larger multipole design, which is available in up to 700 A sizes, each color is physically keyed so as to mate only with a like colored connector, and Anderson published a list of recommended voltage for each color:
