| 1 | Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing. | Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group | 2020 | National Science Review2020，7，12： | 51 |

| 3 | A review on tribology of polymer composite coatings显示文摘Self-lubricating polymer composite coatings,with tailorable tribological and mechanical properties,have been widely employed on mechanical parts to reduce friction and wear,which saves energy and improves the overall performance for applications such as aerospace satellite parts,shafts,gears,and bushings.The addition of functional fillers can overcome the limitations of single-polymer coatings and extend the service life of the coatings by providing a combination of low friction,high wear resistance,high load bearing,high temperature resistance,and high adhesion.This paper compares the heat resistance,and the tribological and mechanical properties of common polymer matrices,as well as the categories of functional fillers that improve the coating performance.Applicable scopes,process parameters,advantages,and limitations of the preparation methods of polymer coatings are discussed in detail.The tribological properties of the composite coatings with different matrices and fillers are compared,and the lubrication mechanisms are analyzed.Fillers reduce friction by promoting the formation of transfer films or liquid shear films.Improvement of the mechanical properties of the composite coatings with fillers of different morphologies is described in terms of strengthening and toughening mechanisms,including a stress transfer mechanism,shear yielding,crack bridging,and interfacial debonding.The test and enhancement methods for the adhesion properties between the coating and substrate are discussed.The coating adhesion can be enhanced through mechanical treatment,chemical treatment,and energy treatment of the substrate.Finally,we propose the design strategies for high-performance polymer composite coating systems adapted to specific operating conditions,and the limitations of current polymer composite coating research are identified. | Yilong REN Lin ZHANG Guoxin XIE Zhanbo LI Hao CHEN Hanjun GONG Wenhu XU Dan GUO Jianbin LUO | 2021 | Friction2021，9，3： | 13 |
| 4 | INFORMATION STRUCTURES AND PRICING DECISIONS IN COMPETING SUPPLY CHAINS显示文摘The paper investigates the pricing decisions of two competing supply chains under the different information structures. Each retailer has private information about the market demand and has the right to decide whether or not to share the information with the manufacturer. Three demand-information structures, i.e., information sharing in both supply chains, information sharing in only one supply chain and information sharing in neither supply chain, are considered. We investigate the value of information by comparing the information structures, and find that the information value not only works in the channel directly, but also does in the competing channel indirectly. Information sharing in a supply chain always benefits its manufacturer, but hurts its retailer; while it benefits both the manufacturer and the retailer of competing supply chain, regardless of whether this competing supply chain has information sharing. From the perspective of channel, when the competition is more intense, information sharing in a supply chain makes this supply chain better off, and when the competition is less intense, the information sharing in a supply chain makes this supply chain worse off. However, it always makes the competing supply chain better off regardless of whether the competing supply chain has information sharing. | Kebing CHEN Jun LIANG Jianbin LI | 2012 | Journal of Systems Science and Systems Engineering2012，21，2： | 9 |
| 5 | Isolation and identification of the thermophilic alkaline desulphuricant strain显示文摘A desulfurization strain that belongs to the thermophilic alkaline desulphuricant is designated as strain GDJ-3 and isolated from Inner Mongolia, China. The colony of the strain shows tiny, yellow, or white-yellow, and it becomes henna with the protracting of cultivated time. The cells are bacilliform (0.3 -0.6 × 1.0-1.2 μm), motive, and Gram negative. The strain GDJ-3 is able to utilize respectively the thiosulphate, sulfate, sulfite, or sulfide as sulfur source, utilize the carbon dioxide as the carbon source, and utilize the ammonium or nitrate as the nitrogen source. According to GenBank data, 16s RNA results of GDJ-3 are in good agreement with Alpha proteobacterrium sp. (97%) and Ochrobactrum sp. (98%). For GDJ-3, the optimum growth temperature is at 45℃, the optimum pH is at 8.5-8.8, and the optimum rocking speed of sorting table is at 150 r/min. Under the optimum culture condition, the cells of the strain can live for about 18 h. In the desulfurization solution, which is prepared according to the composition of DDS solution, the objectionable constituents of sodium thiosulphate and sodium sulfide were added factitiously, and the bacterial cell concentration was set at 107/mL. After the regeneration of the above desulfurization solution by the strain cells, the concentration of sodium thiosulphate was decreased by 14.75 g/L (percentage loss of content 13.21%), the concentration of sodium sulfide was decreased by 0.76 g/L (percentage loss of content 87.36%) in the desulfurization solution in 9.5 hours, and sulfur appeared. Maybe, this kind of strain can be used as the regeneration's bacterial source of DDS solution. | ZHANG JianBin ZHANG Tong MA Kai CHEN GuoHua ZHANG DongYan WEI XiongHui | 2008 | Science China Chemistry2008，51，2： | 9 |
| 6 | Modified graphene as novel lubricating additive with high dispersion stability in oil显示文摘Graphene is a promising material as a lubricant additive for reducing friction and wear.Here,a dispersing method which combines chemical modification of graphene by octadecylamine and dicyclohexylcarbodiimide with a kind of effective dispersant has been successfully developed to achieve the remarkable dispersion stability of graphene in base oil.The stable dispersion time of modified graphene(0.5 wt%)with dispersant(1 wt%)in PAO-6 could be up to about 120 days,which was the longest time reported so far.At the same time,the lubricant exhibits a significant improvement of tribological performance for a steel ball to plate tribo-system with a normal load of 2 N.The coefficient of friction between sliding surfaces was~0.10 and the depth of wear track on plate was~21 nm,which decreased by about 44%and 90%when compared to pure PAO-6,respectively.Furthermore,the analysis of the lubricating mechanisms in regard to the sliding-induced formation of nanostructured tribo-film has been contacted by using Raman spectra and TEM. | Pu WU Xinchun CHEN Chenhui ZHANG Jiping ZHANG Jianbin LUO Jiyang ZHANG | 2021 | Friction2021，9，1： | 9 |
| 7 | Tribological Properties of Few-layer Graphene Oxide Sheets as Oil-Based Lubricant Additives显示文摘The performance of a lubricant largely depends on the additives it involves. However, currently used additives cause severe pollution if they are burned and exhausted. Therefore, it is necessary to develop a new generation of green additives. Graphene oxide(GO) consists of only C, H and O and thus is considered to be environmentally friendly. So the tribological properties of the few-layer GO sheet as an additive in hydrocarbon base oil are investigated systematically. It is found that, with the addition of GO sheets, both the coefficient of friction(COF) and wear are decreased and the working temperature range of the lubricant is expanded in the positive direction. Moreover, GO sheets has better performance under higher sliding speed and the optimized concentration of GO sheets is determined to be 0.5wt%. After rubbing, GO is detected on the wear scars through Raman spectroscopy. And it is believed that, during the rubbing, GO sheets adhere to the sliding surfaces, behaving like protective films and preventing the sliding surfaces from contacting with each other directly. This paper proves that the GO sheet is an effective lubricant additive, illuminates the lubrication mechanism, and provides some critical parameters for the practical application of GO sheets in lubrication. | CHEN Zhe LIU Yuhong LUO Jianbin | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 9 |

| 11 | A facile and general approach for the synthesis of fluorescent silica nanoparticles doped with inert dyes显示文摘A general and facile approach was developed for the synthesis of almost monodisperse fluorescent silica nanoparticles (NPs) doped with inert dyes, which are organic fluorophores that are strongly fluorescent but are hydrophobic or lack a covalent binding group. The prepared NPs were mesoporous and the dye molecules were encapsulated in the pores via hydrophobic interaction with the CTAB template. The NPs were stable and highly fluorescent in aqueous solution, and have potential applications in bioanalysis and fluorescence encoding. | MU Xue WU ChuanLiu LAI JinPing CHEN JianBin ZHENG JinSheng LI Chong ZHAO YiBing | 2011 | Chinese Science Bulletin2011，56，31： | 5 |
| 12 | From Symbols to Embeddings:A Tale of Two Representations in Computational Social Science显示文摘Computational Social Science(CSS),aiming at utilizing computational methods to address social science problems,is a recent emerging and fast-developing field.The study of CSS is data-driven and significantly benefits from the availability of online user-generated contents and social networks,which contain rich text and network data for investigation.However,these large-scale and multi-modal data also present researchers with a great challenge:how to represent data effectively to mine the meanings we want in CSS?To explore the answer,we give a thorough review of data representations in CSS for both text and network.Specifically,we summarize existing representations into two schemes,namely symbol-based and embeddingbased representations,and introduce a series of typical methods for each scheme.Afterwards,we present the applications of the above representations based on the investigation of more than 400 research articles from 6 top venues involved with CSS.From the statistics of these applications,we unearth the strength of each kind of representations and discover the tendency that embedding-based representations are emerging and obtaining increasing attention over the last decade.Finally,we discuss several key challenges and open issues for future directions.This survey aims to provide a deeper understanding and more advisable applications of data representations for CSS researchers. | Huimin Chen Cheng Yang Xuanming Zhang Zhiyuan Liu Maosong Sun Jianbin Jin | 2021 | Journal of Social Computing2021，2，2： | 4 |

| 15 | Injectable kartogenin and apocynin loaded micelle enhances the alleviation of intervertebral disc degeneration by adipose-derived stem cell显示文摘Cell transplantation has been proved the promising therapeutic effects on intervertebral disc degeneration(IVDD).However,the increased levels of reactive oxygen species(ROS)in the degenerated region will impede the efficiency of human adipose-derived stem cells(human ADSCs)transplantation therapy.It inhibits human ADSCs proliferation,and increases human ADSCs apoptosis.Herein,we firstly devised a novel amphiphilic copolymer PEG-PAPO,which could self-assemble into a nanosized micelle and load lipophilic kartogenin(KGN),as a single complex(PAKM).It was an injectable esterase-responsive micelle,and showed controlled release ability of KGN and apocynin(APO).Oxidative stimulation promoted the esterase activity in human ADSCs,which accelerate degradation of esterase-responsive micelle.Compared its monomer,the PAKM micelle possessed better bioactivities,which were attributed to their synergistic effect.It enhanced the viability,autophagic activation(P62,LC3 II),ECM-related transcription factor(SOX9),and ECM(Collagen II,Aggrecan)maintenance in human ADSCs.Furthermore,it is demonstrated that the injection of PAKM with human ADSCs yielded higher disc height and water content in rats.Therefore,PAKM micelles perform promoting cell survival and differentiation effects,and may be a potential therapeutic agent for IVDD. | Chao Yu Dongdong Li Chenggui Wang Kaishun Xia Jingkai Wang Xiaopeng Zhou Liwei Ying Jiawei Shu Xianpeng Huang Haibin Xu Bin Han Qixin Chen Fangcai Li Jianbin Tang Chengzhen Liang Nigel Slater | 2021 | Bioactive Materials2021，6，10： | 3 |

| 17 | An investigation on the tribological behaviors of steel/copper and steel/steel friction pairs via lubrication with a graphene additive显示文摘In this study,the tribological behaviors of graphene as a lubricant additive for steel/copper and steel/steel friction pairs were compared.For the steel/copper friction pair,the graphene sheets remarkably decreased the coefficient of friction and wear scar depth under low loads,but these slightly increased under high loads.The steel/steel friction pair showed excellent tribological properties even under high loads.Severe plastic deformation on the copper surface reduced the stability of the graphene tribofilm because of a rough copper transfer film on the steel during the running-in period.The results provide a better understanding of the mechanism of graphene as a lubricant additive. | Junyuan MAO Guangyan CHEN Jun ZHAO Yongyong HE Jianbin LUO | 2021 | Friction2021，9，2： | 2 |
| 18 | In situ monitoring of the structural change of microemulsions in simulated gastrointestinal conditions by SAXS and FRET显示文摘Microemulsions are promising drug delivery systems for the oral administration of poorly watersoluble drugs. However, the evolution of microemulsions in the gastrointestinal tract is still poorly characterized,especially the structural change of microemulsions under the effect of lipase and mucus. To better understand the fate of microemulsions in the gastrointestinal tract, we applied small-angle X-ray scattering(SAXS) and fluorescence resonance energy transfer(FRET) to monitor the structural change of microemulsions under the effect of lipolysis and mucus. First, the effect of lipolysis on microemulsions was studied by SAXS, which found the generation of liquid crystalline phases. Meanwhile, FRET spectra indicated micelles with smaller particle sizes were generated during lipolysis, which could be affected by CaCl_2, bile salts and lecithin. Then, the effect of mucus on the structural change of lipolysed microemulsions was studied. The results of SAXS and FRET indicated that the liquid crystalline phases disappeared, and more micelles were generated. In summary, we studied the structural change of microemulsions in simulated gastrointestinal conditions by SAXS and FRET, and successfully monitored the appearance and disappearance of the liquid crystalline phases and micelles. | Xia Lv Shuguang Zhang Huipeng Ma Peipei Dong Xiaodong Ma Ming Xu Yan Tian Zeyao Tang Jinyong Peng Haibo Chen Jianbin Zhang | 2018 | Acta Pharmaceutica Sinica B2018，8，4： | 2 |
| 19 | A Geometric Robust Watermarking Algorithm Based on DWT-DCT and Zernike Moments显示文摘This paper proposed a novel multibits watermarking algorithm providing robustness against geometric attacks. The robustness is achieved from three aspects: ① Choosing the in- scribed disk of the host image as the Zernike moments computa- tion domain and the square in the disk as the watermarking em- bedding domain. ② Embedding the watermark in the cascade discrete wavelet transform-discrete cosine transform (DWT-DCT) domain by modulating the specified coefficient pair in each sub block. ③ Saving two selected Zernike moments of the original watermarked image to estimate and correct the geometric attacks before watermark extraction. Experimental results show that the proposed algorithm is robust to any angle of rotation attacks and wide range of scaling attacks, and as well, a variety of other attacks such as lossy compression, common signal processing. | CHEN Yu QU Fang HU Jianbin CHEN Zhong | 2008 | Wuhan University Journal of Natural Sciences2008，13，6： | 2 |
| 20 | Improvement of the lubrication properties of grease with Mn_(3)O_(4)/graphene (Mn_(3)O_(4)#G) nanocomposite additive显示文摘Although grease can effectively lubricate machines,lubrication failure may occur under high speed and heavy load conditions.In this study,Mn_(3)O_(4)/graphene nanocomposites(Mn_(3)O_(4)#G)were synthetized using a hydrothermal method as lubricant additives.The lubrication properties of compound grease with Mn_(3)O_(4)#G nanocomposite additive under heavy contact loads of 600–900 N(3.95–4.59 GPa)were investigated.First,the nanocomposites were dispersed into L-XBCEA 0 lithium grease via successive electromagnetic stirring,ultrasound vibration,and three-roll milling.Compound grease with additives of commercial graphene(Com#G)was also investigated for comparison.Tribological test results revealed that the trace amounts of Mn_(3)O_(4)#G(as low as 0.02 wt%)could reduce the coefficient of friction(COF)of grease significantly.When the concentration of Mn_(3)O_(4)#G was 0.1 wt%,the COF and wear depth were 43.5%and 86.1%,lower than those of pure graphene,respectively.In addition,under the effect of friction,the microstructure of graphene in Mn_(3)O_(4)#G nanocomposites tends to be ordered and normalized.Furthermore,most of the Mn_(3)O_(4) transformed into Mn_(2)O_(3) owing to the high temperature generated from friction.Using the Ar gas cluster ion beam sputtering method,the thickness of the tribofilm was estimated to be 25–34 nm.Finally,the improvement of the lubrication properties was attributed to the synergistic effect of the adsorbed tribofilm,i.e.,the graphene island effect and the filling effect of Mn_(3)O_(4)#G. | Bao JIN Guangyan CHEN Jun ZHAO Yongyong HE Yiyao HUANG Jianbin LUO | 2021 | Friction2021，9，6： | 2 |
