| 1 | Three-dimensional artificial transpiration for efficient solar waste-water treatment显示文摘Solar steam generation is emerging as promising solar-energy conversion technology for potential applications in desalination, sterilization and chemical purification. Despite the recent use of photon management and thermal insulation, achieving optimum solar steam efficiency requires simultaneous minimization of radiation, convection and conduction losses without compromising light absorption.Inspired by the natural transpiration process in plants, here we report a 3 D artificial transpiration device with all three components of heat loss and angular dependence of light absorption minimized, which enables over 85% solar steam efficiency under one sun without external optical or thermal management. It is also demonstrated that this artificial transpiration device can provide a complementary path for waste-water treatment with a minimal carbon footprint, recycling valuable heavy metals and producing purified water directly from waste water contaminated with heavy metal ions. | Xiuqiang Li Renxing Lin George Ni Ning Xu Xiaozhen Hu Bin Zhu Guangxin Lv Jinlei Li Shining Zhu Jia Zhu | 2018 | National Science Review2018，5，1： | 27 |
| 2 | A Simplified Numerical Approach for the Prediction of Rainfall-Induced Retrogressive Landslides显示文摘Retrogressive landslides are common geological phenomena in mountainous areas and on onshore and offshore slopes. The impact of retrogressive landslides is different from that of other landslide types due to the phenomenon of retrogression. The hazards caused by retrogressive landslides may be increased because retrogressive landslides usually affect housing, facilities, and infrastructure located far from the original slopes. Additionally, substantial geomorphic evidence shows that the abundant supply of loose sediment in the source area of a debris flow is usually provided by retrogressive landslides that are triggered by the undercutting of water. Moreover, according to historic case studies, some large landslides are the evolution result of retrogressive landslides. Hence the ability to understand and predict the evolution of retrogressive landslides is crucial for the purpose of hazard mitigation. This paper discusses the phenomenon of a retrogressive landslide by using a model experiment and suggests a reasonably simplified numerical approach for the prediction of rainfall-induced retrogressive landslides. The simplified numerical approach, which combines the finite element method for seepage analysis, the shear strength reduction finite element method, and the analysis criterion for the retrogression and accumulation effect, is presented and used to predict the characteristics of a retrogressive landslide. The results show that this numerical approach is capable of reasonably predicting the characteristics of retrogressive landslides under rainfall infiltration, particularly the magnitude of each landslide, the position of the slip surface, and the development processes of the retrogressive landslide. Therefore, this approach is expected to be a practical method for the mitigation of damage caused by rainfall-induced retrogressive landslides. | LIN Hungchou YU Yuzhen LI Guangxin YANG Hua PENG Jianbing | 2016 | Acta Geologica Sinica(English Edition)2016，90，4： | 2 |
| 3 | NMR used to study the side-reactions between peroxides and antioxidants during the reactive extrusion process of the impact polypropylene显示文摘Side reaction pathways are observed to occur between antioxidants and peroxide during the processing of multiple resin grades mediated by controlled peroxide-induced degradation of impact polypropylene.In the present work,the reaction mechanism and main by-products between antioxidants and peroxides were investigated.The results demonstrate that peroxides greatly accelerate the decomposition reactions,and the free radicals formed from peroxide decomposition react with,for example,the antioxidant AO1010 to produce dehydrogenation of phenyl propionic unit(s)at the a position(cinnamic acid ester moiety),which generates a conjugated system leading to the increased color of the product.It is the first time to confirm the cinnamic acid moiety's existence and report its NMR data.Further,this work confirms the dehydrogenation mechanism by comparison with different sterically hindered phenolic antioxidants.It also systematically summarizes the oxidation and degradation mechanism of AO168 and AO1010 under air and peroxide environments,respectively.Based on present study,clear guidelines are obtained to improve the quality of polymeric products,especially the appearance and stability,during product development. | Chunfa Li Ting Huang Yubin Bao Zhe Chen Guangxin Lin | 2022 | Magnetic Resonance Letters2022，2，2： | 1 |
| 4 | Immunization with recombinant baculovirus expressing the VP6 protein of grass carp reovirus induces immunity in grass carp显示文摘Dear Editor,Grass carp reovirus(GCRV),a member of the genus Aquareovirus in the family Reoviridae(Attoui H,et al,2002),is one of the most virulent aquareoviruses iden-tified so far,leading to high fatality rates(up to 85%)of fingerlings and yearlings of grass carp(Fang Q,et al,2007).No commercial vaccines against GCRV infection have been developed as yet. | Qin Li Liyue Liu Li Lin Zeming Li Guangxin Liu Shusheng Wu Min Wang Lijuan Li Junfa Yuan Gailing Yuan Xueqin Liu | 2014 | Virologica Sinica2014，29，4： | 0 |
