Non-catalytic gas-phase deconstruction methods, such as the homogeneous pyrolysis of lignin dispersed in the gas phase, as explored in the current paper, could become more practically significant as potential biodiesel surrogates if they achieve high yields and selectivity toward low-molecular-weight PAHs.

In the samples of PAL1- and PAL2-modified lignin, the content of S unit and the value of S/G showed a decreasing trend ( Figure 3 d–f).

In fact, there is a clear trend of increasing capacity with both the interlayer spacing and microporosity.

Table 6 demonstrated a decreasing trend from the universal solvent extract (ELE) to the semi-polar solvent extract (EAE), and further to the fraction (CF5).

While an increasing trend in cholesterol values was observed with rising TMAO levels, a direct correlation could not be established.

In addition, the content of compound 2 in the root secretion showed a trend of first increasing and then decreasing with the increase in time.

Conversely, the Γ max values show a decreasing trend.

The nearly significant AB interaction term suggested that the conversion of PWW to pyrolysis oil was also affected.

This indicated a strong synergistic or antagonistic effect between temperature and the N 2 flow rate on the kerosene-like yield, in contrast to the pyrolysis oil yield, where the AB interaction was only marginally significant.

There has been an increasing trend in recent decades to use therapeutically active molecules from natural sources, and some of them have been found to show promising activities in the symptoms as well as in the control of the progression and complexities related to diabetes and Alzheimer’s disease.

According to the results of the ANOVA, the F value of the regression model is 198.00 ( p < 0.01), and the significance level is much less than 0.0001, indicating that the regression variance model is highly significant.

These examples highlight a clear trend towards the development of real-time and field-deployable lead sensors, which could complement advanced laboratory-based techniques and expand the applicability of potentiometric sensing in routine environmental monitoring.

The results obtained for bread samples enriched with buckwheat husk showed significant ( p ≤ 0.05) variations in antioxidant activity between different treatments (type of bread, buckwheat husk concentration), with a clear trend of increased antioxidant activity as the concentration of buckwheat husk increased ( Table 1 ).

A decreasing trend in these ratios during storage indicates oxidative degradation of the UFA [ 41 ].

In contrast, C 4 + selectivity showed a decreasing trend with rising temperature up to 290 °C, then stabilized and remained nearly constant at higher temperatures.

During the entire vegetative period, the amount of chlorophyll a was higher than that of chlorophyll b , and an increasing trend in the chlorophyll a / b ratio was also observed ( Table 2 ).

Later, the content of these pigments maintained a decreasing trend and reached the lowest content (almost 6 times lower than at the beginning of vegetation) at the beginning of September.

Both compounds, as shown in Figure 11 , show highly significant anti-inflammatory activity compared to that of free Chr.

Consequently, there is a clear trend towards replacing CNCbl supplements, which were previously almost the only option on the market, with their natural forms, especially MeCbl [ 35 , 38 ].

Although there is a considerable amount of data in the literature, it remains challenging to identify a clear trend that would lead to an optimized structure with high activity and low toxicity [ 7 ].

The weight of the dual-side chain cleavage reaction pathway generally exhibits an increasing trend with increasing kinetic energy, reaching a plateau at 75 eV and subsequently maintaining fluctuations.

When analyzing ROS levels in HaCaT cells, there is a clear trend that for each sample with Kombucha ferments and peel extract, normalized fluorescence decreases with concentration.

A clear trend of increasing biolubricant yield as the catalyst concentration increased was observed within the range of 0.8 to 2.5% (by mass).

It can be seen in Table 2 that R 2 ≥ 0.97 for all models, and the p value for lack-of-fit (based on a 95% confidence interval), was highly significant.

The effect of 10 μM NAA did not lead to a statistically significant increase in the LPO products; however, the diagram shows a clear trend toward increased LPO activity.
