It can be used in contexts where you are discussing changes or modifications made to the outer layer or appearance of an object or concept.
Example: "The artist decided to alter their surface by applying a new layer of paint to the canvas."
Alternatives: "change their exterior" or "modify their appearance".
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.
Yeast hyphal switching is but one of the ways in which Candida species can alter their surface shape and surface properties.
Third, structural constraints may make it difficult for some pathogens to alter their surface molecules at the sites attacked by host antibodies.
Orbiting near the magnetic equator, these bodies serve as sources and sinks of magnetospheric plasma, while energetic particles from the magnetosphere alter their surfaces.
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].
