1Multi-layered micro/nanofibrous nonwovens for functional face mask filter显示文摘The worldwide COVID-19 pandemic has led to an attention on the usage of personal protective face masks.However,the longevity and safety of the commercial face masks are limited due to the charge dissipation of the electret meltblown nonwovens,which are dominate in the face mask filters.Herein,we design a type of multi-layer structured nonwovens using meltblowing and electrospinning technologies.The complex nonwovens involving meltblown and electrospun fibers are designed to possess multilevel fiber diameters and pore sizes.The micro/nanofibers with porous and wrinkled surface morphologies can well capture particulate matters(PMs),and the multilevel pore sizes contribute to low air resistance under high filtration efficiency.Airflow field simulation was carried out to understand the pressure distribution within the nonwovens in the filtration process.Meanwhile,by adding Ag nanoparticles(AgNPs)as additives,the nonwovens exhibit excellent antibacterial performance.The resultant nonwovens exhibit filtration efficiency of 99.1%for PM0.3 and low pressure drop of 105 Pa under the 10.67 cm/s inlet air velocity,and antibacterial rate of>99.99%for Escherichia coli.These performances and functions make the designed complex nonwovens a promising filter core for face masks.Yuanqiang Xu Xiaomin Zhang Defang Teng Tienan Zhao Ying Li Yongchun Zeng 2022Nano Research2022，15，8：6

16Comparison on Detection Results of PRV Wild Virus Antibody Provided by Different Institutions显示文摘The detection results from different institutions were performed at the first stage of PRV wild virus antibody supervision in swine breeding. The serum samples were collected from 71 individuals and each individual was sampled twice at one week interval. The results showed that the positive coincidences for g E antibody between two institutions were 35. 71% and 45. 45% respectively,with the total detection coincidences of 87. 32% and 91. 55% correspondingly. The positive coincidences for g E antibody between the two detections of each institution were 40. 00% and 75. 00% respectively,with the total detection coincidences of 87. 32%and 97. 18% correspondingly. It indicates that it is very necessary to screen the detection institution at the first supervision stage of PRV wild virus for swine population.Sun Hua Song Zhongxu Zeng Defang Li Lianghua Li Mingbo Dong Binke Mei Shuqi Peng Xianwen Wu Huayu 2015Animal Husbandry and Feed Science2015，7，2：0
