The phrase "a low surface defects" is not correct in English.
It should be "low surface defects" or "a low surface defect" depending on the intended meaning. You can use it when discussing the quality of a surface in manufacturing or materials science, referring to the presence of few or minor imperfections.
Example: "The product was praised for its low surface defects, ensuring a smooth finish."
Alternatives: "few surface imperfections" or "minimal surface flaws."
A low surface roughness, high porosity, small pore size and fewer defects of the supporting substrate significantly favor membrane fabrication and performance.
For this reason we applied polymer complex solution (PCS) synthesis [23] since we found earlier that the PCS method provides sesquioxides with low surface area and defects and no adsorbed species on the surface [24 26].
Indeed, in [1], the study of the structural properties of single-layer h-BN by molecular dynamics (MD) demonstrated that the lowest energy surface defect in single-layer h-BN involves out-of-plane displacement of a nitrogen atom to form a tetrahedron with three boron atoms in the plane.
The coatings must have excellent mechanical and chemical properties at high temperatures to withstand the stresses during molding and simultaneously extreme low surface roughness and defect density.
Dislocations in high quality single crystal CVD diamond are shown to be reduced by using substrates with a combination of low surface damage and low densities of extended defects.
However, the size distribution and the crystallinity of nanoparticles are generally poor because of low synthetic temperature and surface defects [23].
However, as a result of the surface defects formed during the fast growth in microenvironment, CdSe NCs prepared by microreaction exhibited generally low QY of PL, and this situation was exacerbated for the reactions performed in open air [16, 31].
Annealing CNTs above 1500 °C leads to a well graphitisized wall structure of CNTs with a nearly oxygen-free surface with a low number of defects.
Ordered structures such as nanowires should contain a lower density of such surface defects, but suffer from the low surface to volume ratio that leads to much lower dye adsorption capability.
There is a large variety of surface defects for different steel products.
The plenty oxygen-containing defects on the GO surface brought out the low exchange current density, because the surface defects cut down the electrical conductivity [15].
