The phrase "after their surface" is correct and usable in written English.
It can be used in contexts where you are discussing something that occurs or is relevant following the outer layer or exterior of an object or concept.
Example: "The researchers found that the chemical reactions took place after their surface was exposed to the catalyst."
Alternatives: "beyond their surface" or "following their surface".
But soon after, their surface became mottled.
ZSM-5 type zeolite crystals with high coverage were then hydrothermally grown on the SiC nano-whiskers after their surface was properly modified with zeolite precursor gel.
The physical network structure of BFs is also improved after their surface treatment, and as a result, the composites with treated BF have more tensile cycles and higher elongation levels than the one with pristine BF.
The resulting pyrolyzed bamboo sticks were tested as electrodes, after their surface were cleaned with an acid attack to achieve a high degree of purity, as confirmed by TGA and XPS analysis.
Samples were taken out of the water and were weighed after their surface water had been removed.
The samples were subjected to 1000 cycles each, where after their surface resistivity was measured in accordance with previous description.
It was previously published by the authors that granules can either coalesce through Type I (when granules coalesce by viscous dissipation in the surface liquid layer before their surfaces touch) or Type II (when granules are slowed to a halt during rebound, after their surfaces have made contact) (AIChE J. 46 (3) (2000) 529).
The two layers were bonded after their surfaces were processed by a plasma cleaner.
After measuring their surface area, these materials (slide: 5 × 1.5 × 0.16 cm; filaments: length 10 cm, diameter 0.06 cm, 9 filaments per replicate) were anchored at a 30-cm depth below the water surface.
Golgi apparatus and endoplasmic reticulum areas were calculated after outlining their surface based on the staining for GM130 and calreticulin, respectively.
Nevertheless, after their synthesis their surface chemistry needs to be rationally engineered, in order to warrant colloidal stability in biological milieu, as well as to keep their bioactivity.
