| 1 | Preparation of activated carbon from cattail and its application for dyes removal显示文摘Activated carbon was prepared from cattail by H3PO4 activation. The effects influencing the surface area of the resulting activated carbon followed the sequence of activated temperature > activated time > impregnation ratio > impregnation time. The optimum condition was found at an impregnation ratio of 2.5, an impregnation time of 9 hr, an activated temperature of 500°C, and an activated time of 80 min. The Brunauer-Emmett-Teller surface area and average pore size of the activated carbon were 1279 m2/g and 5.585 nm, respectively. A heterogeneous structure in terms of both size and shape was highly developed and widely distributed on the carbon surface. Some groups containing oxygen and phosphorus were formed, and the carboxyl group was the major oxygen-containing functional group. An isotherm equilibrium study was carried out to investigate the adsorption capacity of the activated carbon. The data fit the Langmuir isotherm equation, with maximum monolayer adsorption capacities of 192.30 mg/g for Neutral Red and 196.08 mg/g for Malachite Green. Dye-exhausted carbon could be regenerated effectively by thermal treatment. The results indicated that cattail-derived activated carbon was a promising adsorbent for the removal of cationic dyes from aqueous solutions. | Qianqian Shi Jian Zhang Chenglu Zhang Cong Li Bo Zhang Weiwei Hu Jingtao Xu Ran Zhao | 2010 | Journal of Environmental Sciences2010，22，1： | 13 |
| 2 | An all-round AI-Chemist with a scientific mind显示文摘The realization of automated chemical experiments by robots unveiled the prelude to an artificial intelligence(AI)laboratory.Several AI-based systems or robots with specific chemical skills have been demonstrated,but conducting all-round scientific research remains challenging.Here,we present an all-round AI-Chemist equipped with scientific data intelligence that is capable of performing basic tasks generally required in chemical research.Based on a service platform,the AI-Chemist is able to automatically read the literatures from a cloud database and propose experimental plans accordingly.It can control a mobile robot in-house or online to automatically execute the complete experimental process on 14 workstations,including synthesis,characterization and performance tests.The experimental data can be simultaneously analysed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization,allowing a new hypothesis for the next iteration to be proposed.The competence of the AI-Chemist has been scrutinized by three different chemical tasks.In the future,the more advanced all-round AI-Chemists equipped with scientific data intelligence may cause changes to the landscape of the chemical laboratory. | Qing Zhu Fei Zhang Yan Huang Hengyu Xiao LuYuan Zhao XuChun Zhang Tao Song XinSheng Tang Xiang Li Guo He BaoChen Chong JunYi Zhou YiHan Zhang Baicheng Zhang JiaQi Cao Man Luo Song Wang GuiLin Ye WanJun Zhang Xin Chen Shuang Cong Donglai Zhou Huirong Li Jialei Li Gang Zou WeiWei Shang Jun Jiang Yi Luo | 2022 | National Science Review2022，9，10： | 5 |

| 4 | Efficacy,safety and immunogenicity of hexavalent rotavirus vaccine in Chinese infants显示文摘A randomized,double-blind,placebo-controlled multicenter trial was conducted in healthy Chinese infants to assess the efficacy and safety of a hexavalent live human-bovine reassortant rotavirus vaccine(HRV)against rotavirus gastroenteritis(RVGE).A total of 6400 participants aged 6-12 weeks were enrolled and randomly assigned to either HRV(n?3200)or placebo(n?3200)group.All the subjects received three oral doses of vaccine four weeks apart.The vaccine efficacy(VE)against RVGE caused by rotavirus serotypes contained in HRV was evaluated from 14 days after three doses of administration up until the end of the second rotavirus season.VE against severe RVGE,VE against RVGE hospitalization caused by serotypes contained in HRV,and VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were also investigated.All adverse events(AEs)were collected for 30 days after each dose.Serious AEs(SAEs)and intussusception cases were collected during the entire study.Our data showed that VE against RVGE caused by serotypes contained in HRV was 69.21%(95%CI:53.31-79.69).VE against severe RVGE and RVGE hospitalization caused by serotypes contained in HRV were 91.36%(95%CI:78.45-96.53)and 89.21%(95%CI:64.51-96.72)respectively.VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were 62.88%(95%CI:49.11-72.92),85.51%(95%CI:72.74-92.30)and 83.68%(95%CI:61.34-93.11).Incidences of AEs from the first dose to one month post the third dose in HRV and placebo groups were comparable.There was no significant difference in incidences of SAEs in HRV and placebo groups.This study shows that this hexavalent reassortant rotavirus vaccine is an effective,well-tolerated,and safe vaccine for Chinese infants. | Zhiwei Wu Qingliang Li Yan Liu Huakun Lv Zhaojun Mo Fangjun Li Qingchuan Yu Fei Jin Wei Chen Yong Zhang Teng Huang Xiaosong Hu Wei Xia Jiamei Gao Haisong Zhou Xuan Bai Yueyue Liu Zhenzhen Liang Zhijun Jiang Yingping Chen Jiuwei Zhang Jialiang Du Biao Yang Bo Xing Yantao Xing Ben Dong Qinghai Yang Chen Shi Tingdong Yan Bo Ruan Haiyun Shi Xingliang Fan Dongyang Feng Weigang Lv Dong Zhang Xiangchu Kong Liuyifan Zhou Dinghong Que Hong Chen Zhongbing Chen Xiang Guo Weiwei Zhou Cong Wu Qingrong Zhou Yuqing Liu Jian Qiao Ying Wang Xinguo Li Kai Duan Yuliang Zhao Gelin Xu Xiaoming Yang | 2022 | Virologica Sinica2022，37，5： | 2 |
| 5 | DTHMM based delay modeling and prediction for networked control systems显示文摘In the forward channel of a networked control system (NCS), by defining the network states as a hidden Markov chain and quantizing the network-induced delays to a discrete sequence distributing over a finite time interval, the relation between the network states and the network-induced delays is modelled as a discrete-time hidden Markov model (DTHMM). The expectation maximization (EM) algorithm is introduced to derive the maximumlikelihood estimation (MLE) of the parameters of the DTHMM. Based on the derived DTHMM, the Viterbi algorithm is introduced to predict the controller-to-actuator (C-A) delay during the current sampling period. The simulation experiments demonstrate the effectiveness of the modelling and predicting methods proposed. | Shuang Cong Yuan Ge Qigong Chen Ming Jiang Weiwei Shang | 2010 | Journal of Systems Engineering and Electronics2010，21，6： | 2 |

| 7 | Eco-friendly biodegradable polyurethane based coating for antibacterial and antifouling performance显示文摘Biofouling, which comprises the absorption of proteins and the adhesion of bacteria to the surface of living entities, is a severe concern for the maritime sector since it ultimately leads to hydrodynamic drag,resulting in a higher increase in fuel consumption. As a result, polymer resins are crucial in the marine sector for anti-biofouling coatings. In this work, the poly(caprolactone-ethylene glycol-caprolactone)-p olyurethane(PECL-PU) are prepared through ε-caprolactone(CL), poly(ethylene glycol)(PEG), 4,4'-methylene bis(cyclohexyl isocyanate) and 1,4 butanediol. Our study demonstrate that the PECL-PU copolymer degraded in artificial seawater(5.21%), enzymatic solution(12.63%), and seawater(13.75%)due to the presence of PEG segments in the laboratory-based test under static condition. Because the addition of PEG segments are increased the polymer's amorphous area and decreased the crystallization of the polycaprolactone(PCL) in the copolymer, as demonstrated by differential scanning calorimetry, X-ray diffraction, and water contact angle studies. Therefore, the hydrolysis rates of PECL-PU were higher than the caprolactone-co-polyurethane(CL-PU). The antifouling test showed that PECL-PU3 copolymer had about 90.29% protein resistance, 85.2% Escherichia coli(E. coli) reduction and 94.61% marine diatom Navicula incerta reduction comparison to the control. We have developed an eco-friendly and inexpensive promising degradable polyurethane for reduction of bacterial biofilm, which can preserve the formation of biofouling on marine coating under practical sea conditions. | Abid Ali Bilal Ul Amin Wenwu Yu Taijiang Gui Weiwei Cong Kai Zhang Zheming Tong Jiankun Hu Xiaoli Zhan Qinghua Zhang | 2023 | Chinese Journal of Chemical Engineering2023，54，2： | 1 |

| 10 | Intra-host Ebola viral adaption during human infection显示文摘The onsite next generation sequencing(NGS)of Ebola virus(EBOV)genomes during the 2013–2016 Ebola epidemic in Western Africa provides an opportunity to trace the origin,transmission,and evolution of this virus.Herein,we have diagnosed a cohort of EBOV patients in Sierra Leone in 2015,during the late phase of the outbreak.The surviving EBOV patients had a recovery process characterized by decreasing viremia,fever,and biochemical parameters.EBOV genomes sequenced through the longitudinal blood samples of these patients showed dynamic intra-host substitutions of the virus during acute infection,including the previously described short stretches of 13 serial TNC mutations.Remarkably,within individual patients,samples collected during the early phase of infection possessed Ts at these nucleotide sites,whereas they were replaced by Cs in samples collected in the later phase,suggesting that these short stretches of TNC mutations could emerge independently.In addition,up to a total of 35 nucleotide sites spanning the EBOV genome were mutated coincidently.Our study showed the dynamic intra-host adaptation of EBOV during patient recovery and gave more insight into the complex EBOV-host interactions. | William JLiu Weifeng Shi Wuyang Zhu Cong Jin Shumei Zou Ji Wang Yuehua Ke Xiaofeng Li Mi Liu Tao Hu Hang Fan Yigang Tong Xiang Zhao Wenbin Chen Yuhui Zhao Di Liu Gary Wong Chengchao Chen Chunyu Geng Weiwei Xie Hui Jiang Idrissa Laybor Kamara Abdul Kamara Matt Lebby Brima Kargbo Xiangguo Qiu Yu Wang Xiaofeng Liang Mifang Liang Xiaoping Dong Guizhen Wu George F.Gao Yuelong Shu | 2019 | Biosafety and Health2019，1，1： | 1 |

| 14 | Synthesis and biological evaluation of ^(99m)Tc-HEDTA/HYNIC-MPP4 complex for 5-HT1A receptor imaging显示文摘5-HT1A receptor is associated with a variety of pathophysiology of neuropsychiatric disorders. Accordingly, we have synthesized a new 5-HT1A receptor ligand (HYNIC-MPP4) and labeled it with 99mTc using N-(2-hydroxyethyl)ethylenediaminetriacetic acid (HEDTA) as coligand. 99mTc-HEDTA/HYNIC-MPP4 was prepared under pH 6 at room temperature. Biodistribution of 99mTc-HEDTA/HYNIC-MPP4 in normal mice showed that this complex had moderate brain uptake (0.60% ID·g-1 at 2 min p.i.) and good retention. The hippocampus had the highest radioactivity uptake at 2 min p.i. (1.84% ID·g-1). The ratio of Hipp/CB was 3.1 at 2 min p.i. and increased to 4.4 at 60 min p.i. After blocking with 8-hydroxy-2-(dipropylamino) tetralin, the uptake of hippocampus was decreased significantly from 1.84% ID·g-1 to 0.53% ID·g-1 at 2 min p.i., while the cerebellum had no significant decrease. This 99mTc complex could be a potent agent for 5-HT1A receptor imaging. | FAN WeiWei*, LIN Yan*, ZHANG XianZhong, PANG Yan, MA Cong, TANG ZhiGang, ZHANG JunBo & WANG XueBin Key Laboratory of Radiopharmaceuticals, Ministry of Education, College of Chemistry, Beijing Normal University, Beijing 100875, China | 2009 | Science China Chemistry2009，52，5： | 1 |

| 17 | Petrology and PGE Abundances of High-Cr and High-Al Podiform Chromitites and Peridotites from the Bulqiza Ultramafic Massif, Eastern Mirdita Ophiolite, Albania显示文摘The Bulqiza ultramafic massif, which is part of the eastern Mirdita ophiolite of northern Albania, is world renowned for its high-Cr chromitite deposits. High-Cr chromitites hosted in the mantle section are the crystallized products of boninitic melts in a supra-subduction zone(SSZ). However,economically important high-Al chromitites are also present in massive dunite of the mantle-crust transition zone(MTZ). Chromian-spinel in the high-Al chromitites and dunites of the MTZ have much lower Cr~# values(100 Cr/(Cr+Al))(47.7-55.1 and 46.5-51.7, respectively) than those in the high-Cr chromitites(78.2-80.4), harzburgites(72.6-77.9) and mantle dunites(79.4-84.3). The chemical differences in these two types of chromitites are reflected in the behaviors of their platinum-group elements(PGE).The high-Cr chromitites are rich in IPGE relative to PPGE with 0.10-0.45 PPGE/IPGE ratios, whereas the high-Al chromitites have relatively higher PPGE/IPGE ratios between 1.20 and 7.80. The calculated melts in equilibrium with the high-Cr chromitites are boninitic-like, and those associated with the high-Al chromitites are MORB-like but with hydrous, oxidized and TiO_2-poor features. We propose that the coexistence of both types of chromitites in the Bulqiza ultramafic massif may indicates a change in magma composition from MORB-like to boninitic-like in a proto-forearc setting during subduction initiation. | QIU Tian YANG Jingsui MILUSHI Ibrahim WU Weiwei MEKSHIQI Nezir XIONG Fahui ZHANG Cong SHEN Tingting | 2018 | Acta Geologica Sinica(English Edition)2018，92，3： | 1 |
| 18 | LDL receptor-related protein 1 (LRP1),a novel target for opening the blood-labyrinth barrier(BLB)显示文摘Inner ear disorders are a cluster of diseases that cause hearing loss in more than 1.5 billion people worldwide.However,the presence of the blood-labyrinth barrier(BLB)on the surface of the inner ear capillaries greatly hinders the effectiveness of systemic drugs for prevention and intervention due to the low permeability,which restricts the entry of most drug compounds from the bloodstream into the inner ear tissue.Here,we report the finding of a novel receptor,low-density lipoprotein receptor-related protein 1(LRP1),that is expressed on the BLB,as a potential target for shuttling therapeutics across this barrier.As a proof-ofconcept,we developed an LRP1-binding peptide,IETP2,and covalently conjugated a series of model small-molecule compounds to it,including potential drugs and imaging agents.All compounds were successfully delivered into the inner ear and inner ear lymph,indicating that targeting the receptor LRP1 is a promising strategy to enhance the permeability of the BLB.The discovery of the receptor LRP1 will illuminate developing strategies for crossing the BLB and for improving systemic drug delivery for inner ear disorders. | Xi Shi Zihao Wang Wei Ren Long Chen Cong Xu Menghua Li Shiyong Fan Yuru Xu Mengbing Chen Fanjun Zheng Wenyuan Zhang Xinbo Zhou Yue Zhang Shiwei Qiu Liyuan Wu Peng Zhou Xinze Lv Tianyu Cui Yuehua Qiao Hui Zhao Weiwei Guo Wei Chen Song Li Wu Zhong Jian Lin Shiming Yang | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 0 |
| 19 | Functional Analysis of Dunaliella salina Calmodulin Kinase Gene显示文摘[Objectives] This study was conducted to investigate the function of Dunaliella salina calmodulin kinase(CaM K) gene.[Methods] The sense and antisense gene fragments(223 bp) and spacer sequence(129 bp) of D.salina calmodulin kinase gene were cloned and inserted into the downstream part of the35 S promoter of the eukaryotic expression vector pM DCMGN-Cat.The siRNA expression system of CaM K gene was successfully constructed.The p CaM K-RNAi expression vector was transformed into D.salina cells by the LiA c/PEG-mediated method,giving transgenic D.salina.The expression of CaM K gene was then analyzed by real-time fluorescence quantitative PCR.[Results]The expression of CaM K gene in the transgenic D.salina was significantly reduced,by 70% compared with the control group,suggesting that the expression of CaM K gene was significantly inhibited.The examination of the growth status of D.salina showed that D.salina cell division and proliferation were also affected.It is proved that CaM K gene has a positive regulation effect on the division and proliferation of D.salina cells.[Conclusions] The study provides important information for further elucidating the function and action mechanism of D.salina calmodulin kinase gene. | Zhenyu XING Mingfang WANG Xiangnan GAO Weiwei XU Yuting CONG Xiaojie CHAI | 2020 | Agricultural Biotechnology2020，9，2： | 0 |
