Excerpts

The cathodic zone of the member reacted the most actively, and the potential difference between the cathodic and anodic zones first showed an increasing trend and then decreased with time.

Overall, the magnitude of the tensile stress shows a decreasing trend with increasing angle, with a more significant change occurring in the latter range.

The SEM analysis for the TBT/EG pattern ( Figure 2 b) exhibited TiO 2 particles with plate-like or irregular shapes, along with a strong trend of agglomeration.

On the contrary, if the magnetic field strength is significantly greater than 1500 A/m, the magnetic flux density of the AA under the same magnetic field strength will show a decreasing trend with the increase in temperature.

From the figure, it can be seen that the specimens with different fiber doping and with the coupling effect gradually increased, while the relative dynamic elastic modulus shows a decreasing trend.

Although lower compared to some reports in the literature [ 43 , 68 , 74 , 75 , 76 , 77 ], which show compressive strength increases of 10% to 80%, depending on test age and NT content (1–4 wt.% NT), it can be said that the research results are in agreement with these reports, maintaining an increasing trend, and in contradiction with those indicated by Shekari and Razzaghi [ 60 ], who for a cementitious composite with 1.5% NTs report a reduction in compressive strength of 20.73% at the age of 28 days.

Figure 14 shows a decreasing trend in the plotted curve at oxygen pressures of 10 −17 atm.

Post 60 min: The particle size distribution continues to fluctuate with an overall trend toward larger sizes, indicating ongoing dissolution and recrystallization processes, with an increase in the proportion of larger particles (>1 μm).

From L1 to L7, the tensile strength and modulus of elasticity showed an overall trend of steady decrease ( Figure 6 d).

The bending strength and modulus of elasticity both showed a decreasing trend from L1 to L7 on these two bending directions ( Figure 5 e,f).

In the figure, the C–C/C=C and C–H/C–N stretching modes due to the pyrrole ring in the range of 1319–1594 cm −1 show an increasing trend in their relative intensity in the Ag NW@PPy.

With the increase in BWR content, the S max , S mean , and S total values of bee-like structures of aged asphalt showed a trend of increasing first and then decreasing, and the N value showed a trend of decreasing first and then increasing, indicating that BWR may affect the formation and disaggregation of bee-like structures.

Conversely, at a constant strain rate, the grain size shows an increasing trend with rising deformation temperatures.

With a constant deformation temperature, there is a decreasing trend in grain size as the strain rate increases.

It can be seen from the figure that the compressive strength of each group of concrete test blocks shows an increasing trend with age, but the increasing amplitude is different.

On this basis, with the whisker content increasing from 0% to 0.5%, the proportion of harmless holes in concrete showed a trend of first increasing and then decreasing, while the proportion of multi-damaged holes showed a trend of first decreasing and then increasing, and the proportion of harmless holes was the highest when the whisker content was 0.4% (HF4).

The only exception is represented by the epoxy composite containing the highest boric acid content; The results of mechanical tests in compression mode do not indicate a clear trend of the influence of boric acid content on the mechanical characteristics of the tested epoxy composites.

found nanoscale grain size in the [(Ba 0.85 Ca 0.15 ) 0.995 Nd 0.005 ](Ti 0.9 Hf 0.1 )O 3 ceramics prepared via hydrothermal method exhibited an increasing trend with the increase in sintering temperature and holding time, which significantly affected the dielectric constant and T C temperature [ 22 ].

A comparison between Figure 7 a and the subsequent Figure 7 b–d reveals a clear trend: as batteries experience micro-overcharge cycling, the number of cracks (highlighted within blue circles) on the cathode material surface proliferates [ 28 ].

As the temperature increased, the residual compressive strength and elastic modulus of concrete generally showed a decreasing trend.

Thus, the effect of CO 2 on reducing the diffusion barrier for hydrogen was almost insignificant. 4.

As can be seen in Figure 13 and Figure 14 , this study of the mechanical properties of aged Sikadur (up to 163 days) and Loctite (up to 231 days) shows a clear trend towards a progressive decrease in ultimate tensile strength (UTS) with the exposure time.

As depicted in Figure 8 a, there is a clear trend of the increased adsorption capacity of ARPA with rising temperatures for both dyes, which is indicative of an endothermic adsorption process.

With the increase in temperature and decrease in strain rate, the peak stress shows a decreasing trend.

Moreover, with an increase in CN content, the compressive strength of the cement paste shows an initial increase followed by a decreasing trend.
