As a continuous study on the integrated application of volatile β-pinene as an abundant bioresource, the further and broader activity assessment of β-pinene analogues was necessary. On the basis of previous research, the larvicidal activities were carried out against two agricultural insect pests Plutella xylostella and Mythimna separata. In accordance with the overall insecticidal effect, it was remarkable that compounds 5k and 5l demonstrated extreme activity, with LC50 values 1.846 and 1.621 μg/mL against Plutella xylostella. The preliminary structure–activity relationship (SAR) was analyzed, and compounds with the appropriate amphipathic feature displayed more desirable performance. In the meantime, the quantitative structure–activity relationship (QSAR) model (R 2 = 0.9485, F = 82.94, S 2 = 0.0067) was built. The model indicated the most important structural feature was the μc value, which represented the total hybridization components of the molecular dipole. The work provided a potential and alternative approach to take advantage of a forest resource in agriculture.

“…The optimization method through structural design mainly focuses on changing the structure and material of existing components in the furnace, such as cover [8,9], argon tube [10], insulation partition [11], bottom grille [12], heater [13] and so on. The optimization of process parameters mainly focuses on the investigations of argon ow rate [14], furnace pressure [15], thermal stress[16], heater power [17], growth rate[18], and so on. In recent years, the DS furnace has been developing towards the preparation of large size and high-quality silicon ingots, and the size upgrade and hot zone optimization are still widely concerned by researchers.…”

Size upgrading is the main method to increase production capacity and reduce production costs during the directional solidi cation of silicon ingots. The performance of solar cells depends directly on the quality of the wafer and impurities distributions in silicon ingots. The distributions of oxygen and carbon impurities in G6 and G7 directional solidi cation furnaces are studied. The transient global simulation method is used to calculate the coupled thermal and ow elds in the furnaces, considering the convection of gas and melt, chemical reactions, and segregations of the impurities at the crystal-melt interface. The simulation results show that the distributions of oxygen and carbon impurities change signi cantly in the silicon ingot at different growth stages, especially the position of the highest concentration of carbon impurities has shifted. Compared with the G6 furnace, the average concentrations of oxygen and carbon in silicon crystal in the G7 furnace are reduced by 6.7%, and 7.3% respectively. With the growth of silicon crystal, the average concentration of oxygen gradually decreases, while the average concentration of carbon gradually increases.
