The phrase "acid layer" is correct and usable in written English.
It can be used in contexts related to chemistry, geology, or biology, where it refers to a layer that has acidic properties or characteristics.
Example: "The acid layer in the soil affects the types of plants that can thrive in that environment."
Alternatives: "acidic layer" or "layer of acid".
It is assumed that the ultimate target of these different additions is primarily the outer mycolic acid layer.
Atomic force microscopy (AFM) in the tapping mode showed that a smooth polyacrylic acid layer covered the fiber surfaces.
The superhydrophobicity of the prepared Zn coatings is attributed to the surface micro/nanostructure and the formed stearic acid layer with a low surface energy.
After binding of Rose Bengal (RB) guest molecules to dendrimers, an assay using the Klotz plot showed that the hydrophobic amino acid layer slightly affected the guest site number, but significantly increased intrinsic binding of the dendrimers to guest molecules.
The PEG-modified dendrimers with the hydrophobic amino acid layer were better able to retain guest molecules than the dendrimer without the layer: they are therefore useful for drug delivery.
In order to increase efficiency and sensitivity of immunoassay Raman labels consisting of gold nanorods coated by 5-thio-nitrobenzoic acid layer with covalently bounded antibodies have been constructed.
Photocatalytic activity of the coatings was determined by the destruction of stearic acid layers, monitored using FT-IR spectroscopy.
The work in this manuscript clearly shows that ethanol as a solvent is not suited to form stable organic acid layers on the surface.
The photografting reaction on the top surface of a solution is much faster, and the grafted poly acrylic acid) layers have ultra-high equilibrium swelling ratios (>100) and very high swelling and pH response rates (in seconds).
When modified with organic molecules, such as octadecylsilane or octadecylphosphonic acid layers, the surfaces showed a superhydrophobic behavior.
Photocatalytic activity of the coatings was determined by the destruction of stearic acid layers, monitored using FT-IR spectroscopy and laser desorption ionization (LDI) mass spectrometry.
