Dragonfly wings are known to have relatively large surface features (Ivanova et al., 2013; Nguyen et al., 2013), while polystyrene and silicon wafers are known to be quite smooth (Decuzzi and Ferrari, 2010; Gentile et al., 2010; Zeiger et al., 2013), and all three samples are less conductive than the previously utilized metallic titanium.
He and other scientists — including New Horizons' principal scientist Alan Stern — were curious as to how such a large surface feature became such a conspicuous color.
However, significant differences are observed if only the largest surface features are resolved.
The Great Red Spot is Jupiter's largest surface feature, a swirling red oval storm twice the size of Earth.
Improved telescope technology in the late 19th and 20th centuries allowed astronomers to resolve (that is, see as distinct objects) large-scale surface features on Io.
From Earth, Io remained just a point of light until the late 19th and early 20th centuries, when it became possible to resolve its large-scale surface features, such as the dark red polar and bright equatorial regions.
Simplified triangular representations of molecular surfaces are useful for easy manipulation, efficient rendering and for the display of large-scale surface features.
There is little variability between lightcurves obtained through visible-light and infrared filters, but there are significant deviations in the ultraviolet, suggesting large surface or compositional features near 285° (75° west longitude).
Concluding this section, such properties of zeolites as high porosity and large surface area are key features in the processes of oil removal from water.
More importantly, using 800 nm PMMA microspheres, a hexagonally ordered macroporous crystalline structure can be created, which features large surface area (20.14 m2 g−1) and large, open, interconnected channels for facile reactants and ions diffusions.
Unusually large diamonds with proximal surface features and population characteristics are well known to occur in rivers and streams that drain the stratigraphic succession in the Quiricó Basin, prompting the search for their presumably local primary source(s) and a possibly associated Archean basement or cratonic root.
