| 1 | A Super-robust Armoured Superhydrophobic Surface with Excellent Anti-icing Ability显示文摘It has been proved that the construction of interconnected armour on superhydrophobic surface could significantly enhance the mechanical robustness.Here,a new kind of armour with frame/protrusion hybrid structure was achieved by nanosecond laser technology.Then,this armoured superhydrophobic surface demonstrated excellent durability,which could withstand linear abrasion(~3 N press)800 cycles,water jet test(1.0 MPa pressure)40 times and 100℃treatment 18 days.Particularly,the armoured superhydrophobic sample shows outstanding anti-icing ability,which can speed up the supercooled water dropping(no adhesion within 2 h),increase the freezing delay time by~3 times and maintain low adhesion force(less than 35 kPa)after 30 icing/de-icing cycles.Further finite element analysis and theoretical modeling proved that the developed frame/protuberance hybrid structure could effectively enhance the durability.The relatively low surface accuracy in this study can significantly reduce processing cost,which provides a bright future for the practical application of armour superhydrophobic materials. | Peng Wang Hui Zhao Boyuan Zheng Ximei Guan Bin Sun Yongli Liao Ying Yue Wei Duan Haimin Ding | 2023 | Journal of Bionic Engineering2023，20，5： | 1 |
| 2 | Precipitation regulated soil nematode community and footprint in cropland ecosystems显示文摘●Nematode abundance and footprint show unimodal patterns with precipitation levels.●MAP governed nematode diversity along the precipitation gradient of agroecosystem.●Soil pH determined nematode abundance and footprint in low precipitation levels.Precipitation plays a crucial role in global biodiversity change across terrestrial ecosystems.Precipitation is proven to affect soil organism diversity in natural ecosystems.However,how precipitation change affects the function of the soil nematode community remains unclear in cropland ecosystems.Here,we tested soil nematode communities from different precipitation sites(300 mm to 900 mm)of the agricultural ecosystem.The abundance of total nematodes,fungivores,and plant parasites,together with the footprint of fungivores was significantly affected by mean annual precipitation(MAP)in cropland ecosystem.Plant parasites diversity and footprint showed negative relationships with MAP.The random forest suggested plant parasite footprint was the most responsive to MAP.The structural equation model revealed that MAP affected nematode abundance and footprint indirectly via soil pH;nematode diversity was affected by MAP directly.We conclude that precipitation could act as the main selection stress for nematode diversity among the large gradient of agricultural ecosystems.However,the soil pH may act as a stress factor in determining nematode community and carbon flow in the soil food web.Our study emphasized that using nematode value by trophic group would provide a deep understanding of nematode response to precipitation in cropland ecosystems. | Pingting Guan Jianan Li Cao Hao Jingjing Yang Lihong Song Ximei Niu Ping Wang Mohammad Mahamood Donghui Wu | 2023 | Soil Ecology Letters2023，5，4： | 0 |
| 3 | First Outbreak of Occupational Brucellosis Involving Multiple Clusters--Hubei Province,China,2019显示文摘What is already known on this topic?Human brucellosis,a neglected zoonotic disease,causes more than 500,000 new cases each year globally.The disease is of major public health concern in China,and northern provinces are traditionally endemic areas.What is added by this report?This is the first published outbreak of occupational brucellosis involving multiple clusters in Hubei Province.This investigation characterizes the transmission chain of the outbreak and reveals that provinces south of the Yangtze River are faced with a series of challenges and hurdles to overcome including,but not limited to,health education,law enforcement,and occupational protection.What are the implications for public health practice?In addition to measures aimed at this outbreak,the local agricultural department has issued special notices based on this investigation to adjust and strengthen local eradication program of brucellosis. | Zhong Zhang Yeqing Tong Xinjun Lei Li Liu Zhiqiang Deng Fei Sun Huilai Ma Zhaorui Chang Lijie Zhang Huihui Liu Qi Chen Jianzhong Zheng Haibing Chen Ximei Sun Yang Wu Xuhua Guan | 2020 | China CDC weekly2020，2，39： | 0 |
