| 1 | COVID-19 Super Spreading Event Amongst Elderly Individuals—Jilin Province,China,January 2021显示文摘Summary What is already known on this topic?Clusters of COVID-19 cases often happened in small settings(e.g.,families,offices,school,or workplaces)that facilitate person-to-person virus transmission,especially from a common exposure.What is added by this report?On January 10 and 11,2021,an individual gave three product promotional lectures in Tonghua City. | Laishun Yao Mingyu Luo Tiewu Jia Xingang Zhang Zhulin Hou Feng Gao Xin Wang Xiaogang Wu Weihua Cheng Guoqian Li Jing Lu Bing Zhao Tao Li Enfu Chen Dapeng Yin Biao Huang | 2021 | China CDC weekly2021，3，10： | 13 |

| 4 | Soil splash erosion:An overlooked issue for sustainable rubber plantation in the tropical region of China显示文摘Soil erosion by water is known to be a major driver of land degradation.Splash erosion is the initial stage of water erosion and directly contributes to the detachment of soil particles on sloping land.Splash erosion may be exacerbated or mitigated by ongoing land use/cover change.To estimate the effects of various land use and management systems on splash erosion in the humid tropics,we measured the actual splash erosion under natural rainfall conditions in a tropical rainforest(TR),rubber monoculture(RM),and four rubber agroforestry ecosystems in Xishuangbanna,Southwestern China.The average cumulative splash mass in the RM was 48.7 times higher compared to that in the TR,indicating that the replacement of TR by RM results in severe splash erosion.In the rubber agroforestry systems,the throughfall kinetic energy and splash mass were 34-76%and 86-97%lower,respectively,than that in the RM,indicating that intercropping crops with rubber trees can effectively alleviate erosive power of throughfall and thus splash erosion.Under all land use regimes,in the plots where the litter layer was removed,splash erosion was significantly(2.0-12.1 times)higher and more spatially heterogeneous than in those with litter cover.This highlighted the key role of the forest litter layer in protecting the soil from raindrop detachment.In the study area,the actual splash erosion was strongly correlated with the conditions of precipitation(amount and intensity(I10)of rainfall)and the vegetation structure(especially the crown base height,leaf area index,and canopy cover),but weakly correlated with the soil properties.Given the importance of near-ground intercrops(height<5 m)for improving the vegetation structure,surface cover,and soil conditions,the intercropping of Camellia sinensis and Theobroma cacao with rubber trees is a promising approach for controlling splash erosion and also has benefits on the sus-tainable development of rubber plantation. | Xiai Zhu Xia Yuan Enfu Lu Bin Yang Haofei Wang Yiyuan Du Ashutosh Kumar Singh Wenjie Liu | 2023 | International Soil and Water Conservation Research2023，11，1： | 0 |
| 5 | Preparation of PVA@PEI@BAC@CNC composite nanofibrous film with high efficiency filtration for PM2.5显示文摘It is still a challenge to prepare a water-and polymer-based electrospun air filter film with high efficiency filtration,low pressure drop,and good mechanical properties.To address this issue,polyvinyl alcohol(PVA)was employed as the main material,mixing polyethyleneimine(PEI),bamboo-based activated carbon(BAC)and cellulose nanocrystal(CNC)to construct the air filter film by electrostatic electrospinning.In this system,the negatively charged BAC and CNC are fixed in the system through bonding with the positively charged PEI,showing a double adsorption effect.One is the mechanical filtration of the porous network structure constructed by PVA@PEI electrospun nanofibers,and the other is the electrostatic adsorption of PM2.5 on the surface of BAC and CNC.It is significant that the resulting composite air filter displays a high filtration efficiency of 95.86%,a pressure drop of only 59 Pa,and good thermal stability.Moreover,the introduced methyltrimethoxysilane(MTMS)endows it with good water-resistance.Given these excellent performances,this system can provide theoretical and technical references for the development of water-and polymerbased electrospun air filter film. | Jingda Huang Yi Wang Yuxin Cai Yipeng Liang Shite Lin Enfu Wang Jinhuan Zhong Wenbiao Zhang Kuichuan Sheng | 2023 | Frontiers of Materials Science2023，17，4： | 0 |
