Excerpts

When the additional ammonia content was less than 1000 mg/kg, the fluidity loss after the first hour exhibited a decreasing trend.

The T m of the PHBV blends presented a decreasing trend with the increasing amount of Sn(Oct) 2 .

With the increase of Sn(Oct) 2 content, the tensile strength, impact strength, and elongation at break of the blends all showed a trend of increasing first and then decreasing.

As presented in Figure 7 A, the peak area of AH exhibits a decreasing trend with the increase of incorporating amount.

There is a clear trend toward decreasing impedance values after N-doping, which confirms the improved general electrical conductivity of the N- TiO 2 photoanode substrate if compared with the TiO 2 photoanode substrate without N-doping.

Interestingly, comparing the maximum values of areas (or D eq as previously reported), a decreasing trend moving from SF_EW to SFG_EW is noticeable.

This suggests that all of the elements have a role and are likely to be significant.

The release curve profiles ( Figure 6 a–c) and the correlation equations ( Table S4 ) describing those curves showed fairly significant sorption of peptides 1 – 3 by the fibrous carrier on which they were deposited.

The DC-bias% shows an increasing trend as the phosphating concentration is increased from 0.4 to 1.6 wt.%.

Despite the wide range of E 0 values, the present results highlighted an increasing trend in E 0 values as a function of indenter diameter up to 6 mm.

With prolonged aging time, the strength of the alloy shows an increasing trend at times longer than 5 to 8 h, and then the strength of the alloy decreases again.

The test results showed that with increases in temperature, the uniaxial compressive strength, shear strength, and elastic modulus of concrete all presented a decreasing trend, while the peak strain had an increasing trend.

Therefore, the absorption peak in our measured transient absorption spectrum showed a trend of blue shift first and then red shift with the increase in pressure [ 56 , 57 ].

The P 2 O 5 content of the C 2 S particles showed a decreasing trend from the edge toward the center.

This showed a decreasing trend.

As can be seen from the figure, with the increase in the speed of the powder-feeding motor, the microhardness of the coating on the whole showed a trend of first increasing and then decreasing.

Compared to other samples, the AESO/VDM/DMPA showed an increasing trend over the entire measured time interval.

The Ti NPs showed a decreasing trend in size with respect to suspension time that could be modeled by a forced linear equation with a regression fit (R 2 ) of 0.62.

These results show that the relationship between Y 1 and Y 2 and the equations in the quadratic regression model are extremely significant in accordance with the statistical law.

The output electrical signal of the PVDF/CA EFM nanogenerator showed a trend of increasing first and then decreasing with an increase in the proportion of CA, indicating that adding an appropriate amount of CA could improve the piezoelectric performance of PVDF EFMs.

(2) With the increase of the p parameter, the distribution error shows a decreasing trend, and the peak value error remains unchanged or decreases.

Since Vickers hardness tests are always carried out on an area of microstructure, it must be assumed that these stochastically distributed ferrite or martensite grains influence the recorded hardness value, which explains the partially significant standard deviations of the measured values after the tempering tests or even generally irregular results as demonstrated by Figure 11 .

Thus, the COF of the wire rope shows a decreasing trend in this process.

It was not possible to identify a clear trend for the failure mechanism of either the tests performed at high cross-head rate or under impact conditions.

In using laser cladding to apply HEACs, there are still large blind zones, and the development of the parameters is theoretically and practically significant.
