- As a model compound for redox components on the donor side of photosystem II (PS II) in green plants, a supramolecular complex 2 was synthesized and characterized. In this complex, two {[(2-hydroxy-3-(morpholin-4-ylmethyl)-5-tert-butyl-benzyl)(pyridyl-2-methyl)amino]methyl} arms are linked to the ortho-positions of a phenol which is expected covalently to be linked to Ru(II) tris-bipyridine through an amide bond. The arms on the substituted-phenol can coordinate two Mn(III) ions. The structure of complex 2 was confirmed by electrospray ionization mass spectrometry (ESI-MS) and 2D-NMR (gCOSY, HSQC and HMBC). Its photochemical and electrochemical properties were studied. The results showed that the MLCT band of the compound was red-shifted compared to that of [Ru(byp)(3)](2+) and the luminescence quantum yield was enhanced. In addition, the oxidation potential of ruthenium was higher than the phenol(+)/phenol and Mn(III, IV)/Mn(III) which was consisted with the electron transfer sequence of the donor side of PS II in nature. All these showed that this compound was a good model to mimic the donor side of PS II.

- This study aimed at investigating the mechanism of the human rib fracture under various impact loading conditions based on different failure models. For this purpose, a validated FE thorax model was utilized for analysis of the rib fractures. Based on the human anatomical structures, the human thorax FE model consists of ribs, vertebras, sternum, costal cartilages, internal organs, and soft tissues. Material properties used in this model were based on the published literature. The phenomenon of human rib fractures was simulated in different configurations, including structural experiments of single rib and human thorax frontal crash experiments with a cylinder impactor. Based on different rib fracture failure models in human injury biomechanics, the rib fractures from simulations were analyzed and compared with the impact responses obtained from all of the experiments from the literature. The simulation results with the FE model showed that the applicability of rib fracture failure model would depend on the loading conditions. It was proved that the FE model could be used in research of human rib fracture biomechanics under various impact loading conditions in vehicle traffic accidents.

- The purpose of the current study was to analyze the influence of changes of the material of the human thoracic skeleton and soft tissues on the thorax responses under frontal impact loading conditions. A series of human thorax impact simulations were conducted based on a developed and validated human thorax finite element (FE) model. A number of thoracic response parameters were output to investigate the effect of material property changes on the predicted thoracic responses by using polynomial fitting analysis. The results of the simulations indicated that varying thoracic material properties affects the impact responses with different level. The impact force (Fmax) and chest deflection (Dmax) were obviously affected, and the number of rib fractures (NRF) and T12 accelerations (Gmax-T12) were additionally affected by the material properties. However, the influences of the material properties on the deflection rate (Vmax) and T1 acceleration (Gmax-T1) were small. Specifically, the Fmax, Dmax, and Gmax-T12 were mainly influenced by the soft tissue material properties, while the NRF was primarily determined by the thoracic skeletal structure material properties.

- According to the biological material properties used in predecessors' literature, a FE thorax model is developed based on human anatomical structures. With the model a series of simulations on predecessors' experiments are conducted, including simulations on three-point bending test for ribs performed by Kallieris, the rib structural experiments conducted by Zuoping Li, and Patrick's series experiments of low-speed impact. The results indicate that the thorax FE model can be effectively used for biomechanical researches on human thorax injuries in vehicle collisions.
