| 1 | Numerical study of the effects of local atmospheric circulations on a pollution event over Beijing–Tianjin–Hebei, China显示文摘Currently, the Chinese central government is considering plans to build a trilateral economic sphere in the Bohai Bay area, including Beijing, Tianjin and Hebei(BTH), where haze pollution frequently occurs. To achieve sustainable development, it is necessary to understand the physical mechanism of the haze pollution there. Therefore, the pollutant transport mechanisms of a haze event over the BTH region from 23 to 24 September 2011 were studied using the Weather Research and Forecasting model and the FLEXible-PARTicle dispersion model to understand the effects of the local atmospheric circulations and atmospheric boundary layer structure. Results suggested that the penetration by sea-breeze could strengthen the vertical dispersion by lifting up the planetary boundary layer height(PBLH) and carry the local pollutants to the downstream areas; in the early night, two elevated pollution layers(EPLs) may be generated over the mountain areas: the pollutants in the upper EPL at the altitude of 2–2.5 km were favored to disperse by long-range transport, while the lower EPL at the altitude of 1 km may serve as a reservoir, and the pollutants there could be transported downward and contribute to the surface air pollution.The intensity of the sea–land and mountain–valley breeze circulations played an important role in the vertical transport and distribution of pollutants. It was also found that the diurnal evolution of the PBLH is important for the vertical dispersion of the pollutants,which is strongly affected by the local atmospheric circulations and the distribution of urban areas. | Yucong Miao Shuhua Liu Yijia Zheng Shu Wang Bicheng Chen Hui Zheng Jingchuan Zhao | 2015 | Journal of Environmental Sciences2015，27，4： | 14 |

| 4 | Biphasic mineralized collagen-based composite scaffold for cranial bone regeneration in developing sheep显示文摘Appropriate mechanical support and excellent osteogenic capability are two essential prerequisites of customized implants for regenerating large-sized cranial bone defect.Although porous bone scaffolds have been widely proven to promote bone regeneration,their weak mechanical properties limit the clinical applications in cranioplasty.Herein,we applied two previously developed mineralized collagen-based bone scaffolds(MC),porous MC(pMC)and compact MC(cMC)to construct a biphasic MC composite bone scaffold(bMC)to repair the large-sized cranial bone defect in developing sheep.A supporting frame composed of cMC phase in the shape of tic–tac–toe structure was fabricated first and then embedded in pMC phase.The two phases had good interfacial bond,attributing to the formation of an interfacial zone.The in vivo performance of the bMC scaffold was evaluated by using a cranial bone defect model in 1-month-old sheep.The computed tomography imaging,X-ray scanning and histological evaluation showed that the pMC phase in the bMC scaffold,similar to the pMC scaffold,was gradually replaced by the regenerative bone tissues with comprehensively increased bone mineral density and complete connection of bone bridge in the whole region.The cMC frame promoted new bone formation beneath the frame without obvious degradation,thus providing appropriate mechanical protection and ensuring the structural integrity of the implant.In general,the sheep with bMC implantation exhibited the best status of survival,growth and the repair effect.The biphasic structural design may be a prospective strategy for developing new generation of cranioplasty materials to regenerate cranial bone defect in clinic. | Jingchuan Zheng Zhijun Zhao Yongdong Yang Shuo Wang Yonggang Zhao Yang Xiong Shuhui Yang Zhiye Qiu Tianxi Song Chunyang Zhang Xiumei Wang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
