The phrase "altering their surface" is correct and usable in written English.
It can be used in contexts where changes or modifications to the outer layer or appearance of an object or material are being discussed.
Example: "The artist focused on altering their surface to create a more textured and dynamic visual effect."
Alternatives: "modifying their exterior" or "changing their appearance".
Designed colloids of Mb at pH 4.5 and 7.5 have been mixed with collagen solution at pH 7.5 and 4.5 in different concentrations altering their surface charges.
The fate and impact of CNT in the environmental compartments will be affected by altering their surface properties.
However, the data presented here suggest that the processes altering their surface characteristics are similar, although the features these processes generate are variable.
Therefore, many methodologies and innovative techniques have been developed to enhance the intestinal absorption of particles, either by altering their surface properties or by conjugating a targeting molecule at their surface [14].
Theoretical calculations predict that it is possible to alter the electronic properties of MXenes by altering their surface terminations.
It is already established that infection of RBCs by P. falciparum causes changes in the physical properties of RBCs, altering their surface biochemistry, elasticity, volume, and density.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition that is, the surfaces are either repelled or attracted by water.
These materials were characterized before and after use in a typical CMP process in order to assess changes that may affect their toxicological profile and alter their surface chemistry due to polishing.
Three typical porous materials including copper mesh, fabric, and sponge were dipped into the solution of polyfluorowax-hydrophobic SiO2 to alter their surface texture and chemistry, allowing them to exhibit superhydrophobic property.
A promising approach to overcome these limitations is surface modification of biomedical devices by nanostructured coatings, which can alter their surface energy, roughness, and hydrophilicity, and consequently enhance their biocompatibility as well as providing special functionality such as drug delivery and inhibiting biofilm formation.
Not totally sure if he's saying that some people have the power to alter their surface texture, but if so, this is probably what it would look like if you walked in on them while they're in the middle of it.
