| 2 | Vitamin B2 functionalized iron oxide nanozymes for mouth ulcer healing显示文摘Mouth ulcer is associated with inflammation and high risk of bacterial infection, which aggravates the patient's condition.Currently, there is no effective treatment for mouth ulcer. Herein, we report that vitamin-modified iron oxide nanoparticles improve the healing of mouth ulcer through anti-inflammation and antibacterial activities. We discovered that vitamin B2(VB2)modified iron oxide nanoparticles performed enhanced peroxidase-like, catalase-like, and superoxide dismutase(SOD)-like activities, acting as typical iron oxide nanozymes(IONzymes) with triad activities. In particular, VB2 modification significantly improved the SOD-like activity, thus providing a reactive oxygen species(ROS)-scavenging ability. Cellular antioxidant experiments showed that vitamin B2 modified IONzymes(VB2-IONzymes) protect human oral keratinocytes(HOK) and BALB/3 T3 cells from hydrogen peroxide(H2O2), and these cells have high biocompatibility to eukaryotic cells. In addition, VB2-IONzymes exerted an antibacterial activity against Streptococcus mutans, Staphylococcus aureus, and Escherichia coli. Importantly, VB2-IONzymes accelerated the recovery of mouth ulcer and reduced the local secretion of inflammatory factors in mouse ulcer model via ROS scavenging and antibacterial activity. Taken together, our work demonstrates that vitamin B2 modification endows iron oxide nanoparticles with enhanced enzyme-like activities and VB2-IONzymes may be a promising reagent in the treatment of mouth ulcer because of their intrinsic anti-inflammation and antibacterial capabilities. | Yunhao Gu Yixin Huang Zhiyue Qiu Zhuobin Xu Dandan Li Lei Chen Jing Jiang Lizeng Gao | 2020 | Science China(Life Sciences)2020，63，1： | 10 |
| 3 | High-resolution Surface Relative Humidity Computation Using MODIS Image in Peninsular Malaysia显示文摘Forest fire is a serious disaster all over the world. The Fire Weather Index (FWI) System can be used in ap- plied forestry as a tool to investigate and manage all types of fire. Relative humidity (RH) is a very important parameter to calculate FWI. However, RH interpolated from meteorological data may not be able to provide precise and confident values for areas between far separated stations. The principal objective of this study is to provide high-resolution RH for FWI using MODIS data. The precipitable water vapor (PW) can be retrieved from MODIS using split window tech- niques. Four-year-time-series (2000-2003) of 8-day mean PW and specific humidity (Q) of Peninsular Malaysia were analyzed and the statistic expression between PW and Q was developed. The root-mean-square-error (RMSE) of Q es- timated by PW is generally less than 0.0004 and the correlation coefficient is 0.90. Based on the experiential formula between PW and Q, surface RH can be computed with combination of auxiliary data such as DEM and air temperature (Ta). The mean absolute errors of the estimated RH in Peninsular Malaysia are less than 5% compared to the measured RH and the correlation coefficient is 0.8219. It is proven to be a simple and feasible model to compute high-resolution RH using remote sensing data. | PENG Guangxiong LI Jing CHEN Yunhao Abdul Patah NORIZAN Liphong TAY | 2006 | Chinese Geographical Science2006，16，3： | 9 |

| 5 | Hierarchical coupling effect in hollow Ni/NiFe2O4-CNTs microsphere via spray-drying for enhanced oxygen evolution electrocatalysis显示文摘Design and fabrication of cost-effective transition metal and their oxides-based nanocomposites are of paramount significance for metal-air batteries and water-splitting.However,the traditional optimized designs for nanostructure are complicated,low-efficient and underperform for wide-scale applications.Herein,a novel hierarchical framework of hollow Ni/NiFe2O4-CNTs compositemicrosphere forcibly-assembled by zero-dimensional(OD)Ni/NiFo204 nanoparticle(<16 nm)and one-dimensional(1D)self-supporting CNTs was fabricated successfully.Benefitted from the unique nanostructure,such monohybrids can achieve remarkable oxygen evolution reaction(OER)performance in alkaline media with a low overpotential and superior durability,which exceeds most of the commercial catalysts based on IrO/RuO2 or other non-noble metal nanomaterials.The enhanced OER performance of Ni/NiFe2OA-CNTs composite is mainly ascribed to the increased catalytic activity and the optimized conductivity induced by the effects of strong hierarchical coupling and charge transfers between CNTs and Ni/NiFe204 nanoparticles.These effects are greatly boosted by the polarized heterojunction interfaces confirmed by electron holography.The density functional theory(DFT)calculation indicates the epitaxial Ni further enriches the intrinsic electrons contents of NiFe204 and thus accelerates absorption/desorption kinetics of OER intermediates.This work hereby paves a facile route to construct the hollow composite microsphere with excellent OER electrocatalytic activity based on non-noble metal oxide/CNTs. | Xuefeng Yu Guanyu Chen Yizhe Wang Jiwei Liu Ke Pei Yunhao Zhao Wenbin You Lei Wang Jie Zhang Linshen Xing Jingjun Ding Guangzhou Ding Min Wang Renchao Che | 2020 | Nano Research2020，13，2： | 3 |
| 6 | Distribution of Asbestos Enterprises and Asbestosis Cases--China, 1997−2019显示文摘What is already known on this topic?Asbestos is classified as a Class I Carcinogen by the International Agency for Research on Cancer(IARC)because exposure causes mesothelioma and lung cancer in addition to asbestosis and plaques.So far,asbestos has been banned in 67 countries,but chrysotile,a commonly encountered form of asbestos,is still widely used in China and most developing countries.Most asbestos-caused cancers are not reported,recorded,and compensated in many countries.What is added by this report?Enterprises manufacturing asbestos products have been migrating from economically developed Eastern China to relatively underdeveloped central and western regions between 2010 and 2019.Asbestosis cases reported in Tianjin,Beijing,Shandong,Xinjiang,Gansu,Qinghai,and Sichuan accounted for a large proportion of the total cases in China,which was inconsistent with the distribution of asbestos-related enterprises(AREs).The reported asbestosis cases versus total pneumoconiosis cases declined from 2.81%to 0.39%from 2006–2017,and this proportion reached 0.69%in 2018.What are the implications for public health practice?Robust occupational and environmental health assessments and reporting are needed to define the epidemiology of asbestos-related lung diseases,and management of using asbestos and existing products containing asbestos need strengthening and follow-up.Enterprises should be encouraged to use safer substitutes and gradually ban asbestos materials in China. | Mingfeng Chen Huanqiang Wang Jianfang Zhang Chen Yu Weidong Liu Yunhao Xu | 2020 | China CDC weekly2020，2，18： | 2 |
| 7 | Changes and spatial patterns of eco-environment in the farming-pastoral region of northern China显示文摘This paper firstly selects 10 kinds of indexes to reflect eco-environment background condition and builds the multi-subject spatial database by using ground meteorological data, remote sensing data and DEM. It then discusses in detail the methods about evaluating eco-environment background condition and analyzing eco-environment change. The eco-environment background conditions of 1989 and 1999 are synthetically appraised. Finally, the paper analyzes the spatial distribution, quantitative change, the trend of change, the areas of change and the dynamic spatial pattern of eco-environment. The results are as follows: (1) The eco-environment background condition becomes worse from southeast to northwest in the farming-pastoral region of northern China. (2) The eco-environment background condition deteriorates from 1989 to 1999. (3) In the adjacent areas of Shanxi-Shaanxi-Inner Mongolia-Gansu-Ningxia, Horqin Sandy Land and its peripheries, and eastern Qinghai province, eco-environmental deterioration is very serious. | JIANG Weiguo LI Jing LI Jiahong CHEN Yunhao WU Yongfeng | 2005 | Journal of Geographical Sciences2005，15，3： | 2 |

| 9 | WiSH:WiFi-Based Real-Time Human Detection显示文摘Sensorless sensing using wireless signals has been rapidly conceptualized and developed recently. Among numerous applications of WiFi-based sensing, human presence detection acts as a primary and fundamental function to boost applications in practice. Many complicated approaches have been proposed to achieve high detection accuracy, but they frequently omit various practical constraints such as real-time capability, computation efficiency, sampling rates, deployment efforts, etc. A practical detection system that works in realworld applicati ons is lacki ng. In this paper, we design and implement WiSH, a real-time system for con tactless human detection that is applicable for whole-day usage. WiSH employs lightweight yet effective methods and thus enables detection under practical conditions even on resource-limited devices with low signal sampling rates. We deploy WiSH on commodity desktops and customized tiny no des in different everyday scenarios. The experimental results dem on strate the superior performance of WiSH, which has a detection accuracy of >98% using a sampling rate of 20 Hz with an average detection delay of merely 1.5 s. Thus, we believe WiSH is a promising system for real-world deployment. | Tianmeng Hang Yue Zheng Kun Qian Chenshu Wu Zheng Yang Xiancun Zhou Yunhao Liu Guilin Chen | 2019 | Tsinghua Science and Technology2019，24，5： | 2 |
