Multiscale Modeling and Simulation of Falling Collision Damage Sensitivity of Kiwifruit.

Falling damage is the most common form of damage sustained by kiwifruit during the process of picking and post-processing, and it is difficult to conduct a quantitative analysis of this phenomenon through traditional experimental methods. In order to deeply understand the sensitivity of kiwifruit to falling collision damage, the finite element numerical simulation method was used to evaluate and predict the sensitivity of kiwifruit to falling collision damage during harvesting. First, we obtained the appearance characteristics of kiwifruit through reverse engineering technology and determined the geometric and mechanical property parameters of kiwifruit through physical mechanics experiments.

Nucleation and growth of BaFxCl2-x nanorods.

Different ratios and sizes of Ba2F3Cl (BaFxCl2-x, x=1.5) nanorods and nanowires and orthorhombic BaF2 (BaFxCl2-x, x=2) nanorods were prepared by using a liquid-solid-solution approach at 160 approximately 180 degrees C. The processes and results of the experiments conducted to prepare monodisperse Ba2F3Cl nanorods and nanowires showed that the specific surface area increased as the initial concentrations were multiplied.
