Introduction In modern engineering fields such as aerospace, structural design typically focuses on weight reduction while maintaining performance, with an overall trend toward integrating materials, structures, and functionality [ 1 ].
For the MWCNT/Au sensor, as shown in Figure 8 b, the resistance showed a trend of decreasing with the increase in hydrogen pressure above 10 −5 Pa, and the resistance recovered by about 70~95% within one hour after terminating the hydrogen.
The silica content is highly significant in pozzolans used as an additive or partial replacement for cement in concrete, as the silica present in these ashes can react with the calcium hydroxide released during cement hydration, forming calcium silicate hydrates (C-S-H) [ 7 ], which are responsible for the mechanical properties of cement [ 1 , 8 ].
It can be seen that due to the combined effect of the diffusion mechanism and the agglomeration mechanism, the further increase in rare earth content in a certain range will make the size of rare earth inclusions have an increasing trend.
On the other hand, when the deflection angle was maintained at a certain value and the gradient spacing was increased to 0.12, a decreasing trend both in flexural strength and fracture toughness was observed.
(6) v ω = d s d t = π D v 360 1 D x − x 2 According to Figure 2 c, it can be seen that v ω shows an increasing trend from the center to the edge of the brass wire.
At the same time, it can also be seen from the figure that the overall transmembrane pressure difference before and after cleaning shows a slightly increasing trend. 4.
In the linear viscoelastic region (LVR) at small strains (<0.1), G′ remains relatively stable, with a clear trend of increasing stiffness as the glass bead concentration increases.
Additionally, we identified positive and highly significant correlations between Ni content and Cu, Mn, and Co; between Cu content and Mn and Co; and between Mn content and Co.
Across all three rotation speeds, the I D /I G ratio exhibits a decreasing trend with prolonged growth time, though a sudden increase occurs at 15 min.
As shown in Figure 4 , no significant differences in I D /I G were observed among CNTs prepared with varying Ni contents, while the CNT yield exhibited an increasing trend with higher Ni catalyst loading. 3.3.
After tempering at 200–800 °C, the hardness of the 1Cr13 specimens showed a trend of first increasing, then significantly decreasing and finally rapidly increasing with the increase in the tempering temperature, while the hardness of 2Cr13 showed a consistent decreasing trend, after tempering at 200–770 °C, with the increase in the tempering temperature.
Among these, the thermal decomposition temperatures of PBPR-1, PBPR-2, and PBPR-5 show a gradual increase, while the weight loss rate during decomposition exhibits an increasing trend.
