The phrase "a decrease in thickness" is correct and usable in written English.
It can be used in contexts discussing materials, measurements, or physical changes where thickness is relevant.
Example: "The study observed a decrease in thickness of the material after prolonged exposure to heat."
Alternatives: "a reduction in thickness" or "a thinning of the material."
With a decrease in thickness there was a mode change from highly localized to non-localized deformation, with the critical thickness dependent on annealing temperature.
Characterization by X-ray diffraction, scanning electron microscopy and transmission electron microscopy/selected-area electron diffraction reveals that the rolling procedure results in a decrease in thickness of the elemental layers to below 0.1 μm and a reduction in grain size to below 50 nm, but does not induce formation of an intermediate phase.
Furthermore, with the increase in the amount of SS in the dry gel, the framework of SAPO-34 particles transformed to a plate-like structure with a decrease in thickness, suggesting that the particles mainly grew on the periphery of the nanosheet-like structure of the SD.
Scheimpflug tomography-measured pachymetry in Figure 8 shows a decrease in thickness at the 1-month follow-up and a gradual increase in both groups thereafter.
Both epithelial and connective tissues showed a decrease in thickness in roxithromycin treated rats in comparison with animals from the control groups.
After 24 weeks of treatment, most of the control cartilage showed a decrease in thickness, a marked loss of proteoglycan, chondrocyte clustering and cell death.
Moreover, macular edema may be resolved but damage to photoreceptors does not; therefore a decrease in ORL thickness would be a more important visual prognostic factor than the total retinal thickness which may change over time.
The decrease in width of the isotherms with increasing Zr concentration is due to a decrease in film thickness, leading to a decrease in the amount of hydrogen absorbed and hence the magnitude of the optical change.
Increasing the quenching speed can result in a decrease in ribbon thickness and grain boundary width.
The addition of graphene nanosheets leads to a decrease in unburned thickness of 12.8%.
A decrease in coating thickness and a reduction in surface roughness was however observed indicating, a change in coating chemistry.
