Particularly for a rough surface, this absorption effect would make the surface smoother and decrease the frictional resistance further.
The surface structure was smoother with decreasing drying pressure.
Similar observation has been reported by Ichikawa et al. that the higher growth temperature results in a smoother surface with a decrease of the In composition[28].
Comparing Figure 4a,b,c, which presents 3-D views of the film surface morphology, it can be noted that the surface becomes smoother and the RMS value decreases as the RTA temperature increases from room temperature to 650°C.
CsTFA-derived films become smoother, and the grain size gradually decreased upon increasing the molar ratio of CsTFA PbBr2 (Supplementary Figure 4a d), which further confirms the beneficial role of TFA− ions in enhancing the density of CsPbBr3 nuclei.
The surfaces treated with multiple steps of decreasing energy produced a smoother surface with lower peak heights and a slightly higher increase in the hardness than the surface treated with only a single step.
Using native immature and mature cartilage as reference, we observed that growth factor-treated immature cartilages displayed increased nano-compressive stiffness, decreased surface adhesion, decreased water content, increased collagen content and smoother surfaces, correlating with a convergence to the mature cartilage phenotype.
This occurred because the roller tooth cut into the Au substrate, whose imprint force decreased with the tooth's smoother geometry.
When the TEOS/CMC-COOH ratio is decreased, hollow silica microcoils with smoother surface are obtained, suggesting that silica formation on the CMC-COOH surface is favoured over that occurring in the bulk solution (see Figure 5c,d).
First of all, the path of ΔCCC balance is smoother because the coefficient is gradually increasing or decreasing and the change between every 2 months is similar.
