A novel high-efficiency composite photocatalyst, carbon quantum dots (CQDs) are embedded onto out-surface surface of the TiO2 nanotubes (TNTs) with high percentage of photocatalytic reactive facets, was fabricated through an improved hydrothermal method.
He showed how complex function theory illuminates the study of minimal surfaces (surfaces of least area that span a given boundary).
Images of real engineering surfaces, surfaces of adhesive wear particles and trabecular bone were used for the tests.
For example, in a study conducted in an ICU, multiple-antibiotic-resistant Acinetobacter spp. isolates were recovered from bed surfaces, surfaces of equipment, floor mops (when dry) and curtains [ 18].
The method is based on morphometric determination of relative surface (surface density) and volume (volume density).
Up close, their performances deliver a tremulous, tensile control, a precision that shivers with the passions straining to break out just below the surface the surface of behavior, the surface of decorum, the surface of the skin.
"The surface will look like the surface of the moon".

The reception desk has a pock-marked, sand-colored surface that resembles the surface of Venus.
There is not a single flat surface other than the surface of the river".
In a geometrical sense, curved surfaces, like the surface of a sphere, just don't lie flat — they don't have enough surface area.
