The phrase "a compact layer of" is correct and usable in written English.
It can be used to describe a thin, dense, or tightly packed layer of a material or substance.
Example: "The geologist noted a compact layer of sedimentary rock that indicated a period of significant geological activity."
Alternatives: "a dense layer of" or "a thin layer of".
As aforementioned, Pt was deposited on the surface of Ag wires as a compact layer of nanocrystals.
Via spray pyrolysis at 500 °C, a compact layer of TiO2 substrate was deposited on FTO glass.
With respect to 1-D Au-Ag nanostructure, AuAg alloy nanocrystals were deposited on the surface of Ag wires as a compact layer of nanocrystals.
Powders used in additive manufacturing (AM) are spread onto a compact layer of particles for sintering and this process is repeated layer by layer to form the final products.
When the concentration of ({text{Zn}}({text{OH}})_{4}^{2 - }) exceeds the solubility product of Zn(OH 2, precipitation of a compact layer of Zn(OH 2 will occur on the anode surface.
A compact layer of TiO2 was first prepared by spin coating 0.38 M ethanolic solution of di-isopropoxytitanum bis acetylacetonate) on the FTO surface of the substrate at 3,000 rpm for 10 s.
A series of perovskite-based solar cells were fabricated wherein a compact layer (CL) of TiO2 of varying thickness (0 390 nm) was introduced by spray pyrolysis deposition between fluorine-doped tin oxide (FTO) electrode and TiO2 nanoparticle layer in perovskite-based solar cells.
Two different stages of growth were observed, the first corresponding to the formation of a compact layer with average thickness of about 200 nm, the second corresponding to the growth of a branched structure.
The process is repeated several times until a thin, compact layer of red frosting tops each court.
The internal crack surfaces were covered with a thick, compact layer of healing products, mainly composed of calcite and ettringite.
Then a thin compact layer of TiO2 nanoparticles referred to as the blocking layer (approximately 80 nm) is deposited by aerosol spray-pyrolysis at 450°C using ambient air as carrier gas[15].
