| 1 | Catalytic hydrogenation of aromatic nitro compounds by functionalized ionic liquids-stabilized nickel nanoparticles in aqueous phase:The influence of anions显示文摘Two kinds of nickel nanoparticles (NPs) well-dispersed in aqueous phase have been conveniently prepared by reducing nickel(II) salt with hydrazine in the presence of amino group (-NH2) functionalized ionic liquids:1-(3-aminopropyl)-2,3-dimethylimidazolium bromide ([AMMIM][Br]) and 1-(3-aminopropyl)-2,3-dimethylimidazolium acetate ([AMMIM][AcO]).The Ni(0) particles are composed of smaller ones which assemble in a blackberry-like shape.The Ni nanoparticles stabilized with [AMMIM][AcO] are much larger than those stabilized with [AMMIM][Br],and the former unexpectedly give much higher activity in the selective hydrogenation of citral and nitrobenzene (NB) in aqueous phase.The Ni(0) nanocatalysts dispersed in aqueous phase are stable enough to be reused at least five times without significant loss of catalytic activity and selectivity during the catalytic recycles. | HU Yu YU YinYin ZHAO XiuGe YANG HanMing FENG Bo LI Huan QIAO YunXiang HUA Li PAN ZhenYan HOU ZhenShan | 2010 | Science China Chemistry2010，53，7： | 3 |
| 2 | Alteration of dominant cyanobacteria in different bloom periods caused by abiotic factors and species interactions显示文摘Freshwater cyanobacterial blooms have drawn public attention because they threaten the safety of water resources and human health worldwide.Heavy cyanobacterial blooms outbreak in Lake Taihu in summer annually and vanish in other months.To find out the factors impacting the cyanobacterial blooms,the present study measured the physicochemical parameters of water and investigated the composition of microbial community using the 16S rRNA gene and internal transcribed spacer amplicon sequencing in the months with or without bloom.The most interesting finding is that two major cyanobacteria,Planktothrix and Microcystis,dramatically alternated during a cyanobacterial bloom in 2016,which is less mentioned in previous studies.When the temperature of the water began increasing in July,Planktothrix appeared first and showed as a superior competitor for M.aeruginosa in NO3^−-rich conditions.Microcystis became the dominant genus when the water temperature increased further in August.Laboratory experiments confirmed the influence of temperature and the total dissolved nitrogen(TDN)form on the growth of Planktothrix and Microcystis in a co-culture system.Besides,species interactions between cyanobacteria and non-cyanobacterial microorganisms,especially the prokaryotes,also played a key role in the alteration of Planktothrix and Microcystis.The present study exhibited the alteration of two dominant cyanobacteria in the different bloom periods caused by the temperature,TDN forms as well as the species interactions.These results helped the better understanding of cyanobacterial blooms and the factors which contribute to them. | Zhenyan Zhang Xiaoji Fan WJ.G.M.Peijnenburg Meng Zhang Liwei Sun Yujia Zhai Qi Yu Juan Wu Tao Lu Haifeng Qian | 2021 | Journal of Environmental Sciences2021，33，1： | 2 |
| 3 | Epoxidation of olefins with hydrogen peroxide catalyzed by a reusable lacunary-type phosphotungstate catalyst显示文摘Olefins and allylic alcohols have been epoxidized with commercially available hydrogen peroxide (30% H2O2) using a phase transfer catalyst,composed of cetyltrimethylammonium cations and a lacunary-type phosphotungstate anion [PW11O39]7-or the complete Keggin-type heteropolyanion [PW12O40]3-,under two-phase conditions using ethyl acetate as the solvent. It was found that the lacunary-type catalyst showed higher activity and better recyclability than the complete Keggin-type catalyst under the same reaction conditions. 31P NMR spectroscopy and solubility measurements for the two catalysts revealed that the [PW11O39]7-anion had a much faster degradation rate than the [PW12O40]3-anion in an excess of H2O2,which resulted in the formation of more catalytically active species. As a result,the lacunary-type phosphotungstate anion-based catalyst gave a better catalytic performance than the complete Keggin-type anion in ethyl acetate. | HUA Li,QIAO YunXiang,LI Huan,FENG Bo,PAN ZhenYan,YU YinYin,ZHU WenWen & HOU ZhenShan Key Laboratory for Advanced Materials Research Institute of Industrial Catalysis,East China University of Science and Technology,Shanghai 200237,China | 2011 | Science China Chemistry2011，54，5： | 1 |

| 5 | Effect of Rare Earth (Niobium) on Costed and Hot-Rolled Microstructure and Properties of Heavy Rail Steels显示文摘A compared investigation was made on the microstructure and mechanical properties of continuous casting square blanks of BNbRE and U71Mn heavy rail steels having eutectoid composition. The variation of solidified structure of the square blanks was demonstrated by measuring hardness. The observation to the structure and inclusions in the head, waist and base of the hot-rolled rails of the test steels were carried out with optical microscope and SEM. It is found that the casting blanks of both tested steels compose of three areas with constant hardness and three hardness varying areas, and there is considerable P-eutectic structure in the blank of the U71Mn steel. The distribution of the inclusions in the U71Mn steel rail is mainly oxides in both rail head and rail base, and is mainly MnS in the waist of the rail. There has strong effect of the addition of rare earth elements on them. The discussion on these results was made. | Yu Ning Sun Zhenyan Ji Jingwen Ren Xinjia Wang Yunsheng Wang Longmei | 2005 | Journal of Rare Earths2005，23，5： | 1 |

| 8 | Research for length change of four seasons over China in recent 47 years显示文摘Using daily temperature data from 599 Chinese weather stations during 1961-2007, the length change trends of four seasons during the past 47 years were analyzed. Results show that throughout the region, four seasons' lengths are: spring becomes shorter (?0.8 d/10yrs), summer becomes longer (3.2 d/10yrs), autumn (?0.5 d/10yrs) and winter (?1.6 d/10yrs) becomes shorter. This trend is different in spatial distribution, namely it is very obvious in northern than southern China, and also remarkable in eastern than western China. Summer change is most obvious, but autumn has little change comparatively. This trend is highly obvious in North, East, Central and South China. In the Southwest starting in the 21st century, summer becomes longer and winter shortens. The trend in the Plateau region since the 1980s is that spring becomes longer and winter shortens. The average annual temperature increased during the past 47 years, and the change of the average annual temperature precedes seasons' length. Thus, the average annual temperature has a certain influence on the length change of seasons. | ZhenYan Yu GuangZhou Fan Wei Hua DingWen Zhou Xin Lai YaXing Liu | 2011 | Research in Cold and Arid Regions2011，3，6： | 1 |
| 9 | Activating Connexin43 gap junctions primes adipose tissue for therapeutic intervention显示文摘Adipose tissue is a promising target for treating obesity and metabolic diseases.However,pharmacological agents usually fail to effectively engage adipocytes due to their extraordinarily large size and insufficient vascularization,especially in obese subjects.We have previously shown that during cold exposure,connexin43(Cx43)gap junctions are induced and activated to connect neighboring adipocytes to share limited sympathetic neuronal input amongst multiple cells.We reason the same mechanism may be leveraged to improve the efficacy of various pharmacological agents that target adipose tissue.Using an adipose tissue-specific Cx43 overexpression mouse model,we demonstrate effectiveness in connecting adipocytes to augment metabolic efficacy of theβ_(3)-adrenergic receptor agonist Mirabegron and FGF21.Additionally,combing those molecules with the Cx43 gap junction channel activator danegaptide shows a similar enhanced efficacy.In light of these findings,we propose a model in which connecting adipocytes via Cx43 gap junction channels primes adipose tissue to pharmacological agents designed to engage it.Thus,Cx43 gap junction activators hold great potential for combination with additional agents targeting adipose tissue. | Yi Zhu Na Li Mingyang Huang Xi Chen Yu AAn Jianping Li Shangang Zhao Jan-Bernd Funck Jianhong Cao Zhenyan He Qingzhang Zhu Zhuzhen Zhang Zhao VWang Lin Xu Kevin W.Williams Chien Li Kevin Grove Philipp E.Scherer | 2022 | Acta Pharmaceutica Sinica B2022，12，7： | 0 |
| 10 | Assessment of residual chlorine in soil microbial community using metagenomics显示文摘Chlorine-containing disinfectants have been widely used around the world for the prevention and control of the COVID-19 pandemic.However,at present,little is known about the impact of residual chlorine on the soil micro-ecological environment.Herein,we treated an experimental soil-plant-microbiome microcosm system by continuous irrigation with a low concentration of chlorine-containing water,and then analyzed the influence on the soil microbial community using metagenomics.After 14-d continuous chlorine treatment,there were no significant lasting effect on soil microbial community diversity and composition either in the rhizosphere or in bulk soil.Although metabolic functions of the rhizosphere microbial community were affected slightly by continuous chlorine treatment,it recovered to the original status.The abundance of several resistance genes changed by 7 d and recovered by 14 d.According to our results,the chlorine residue resulting from daily disinfection may present a slight long-term effect on plant growth(shoot length and fresh weight)and soil micro-ecology.In general,our study assisted with environmental risk assessments relating to the application of chlorine-containing disinfectants and minimization of risks to the environment during disease control,such as COVID-19. | Yitian Yu Qi Zhang Zhenyan Zhang Nuohan Xu Yan Li Mingkang Jin Guoqiang Feng Haifeng Qian Tao Lu | 2023 | Soil Ecology Letters2023，5，1： | 0 |

| 12 | Internal Friction and Profile of Property and Structure of PD_3 and PD_3RE Rail Steels显示文摘The profile of both hardness and microstructure of continuous casting blanks and rails of PD3 heavy rail steel and PD3RE steel containing small amount of rare earth(RE) added from tundish were studied. It is found that the addition of RE makes the fluctuation of the hardness value decrease, and inhibits effectively and/or even removes lower hardness value(zone) in the centric area of the blank with a cross section of 280 mm×380 mm, and that the surface layer in the rail head of PD3RE steel is obviously hardened and the reason causing this hardening is due to the thinning of the pearlite structure. The metallographic observation shows that there exists a Fe-P(C) eutectic structure in the blank center of the PD3 steel containing only 0.016%P, while the addition of RE can fully inhibit this structure. The internal friction measured on the specimens of the rail waist indicates that besides decreasing internal stress in the rail waist and increasing content of solution carbon in ferrite, the addition of RE also enhances nitriability of surface layer of the rail. | Li Huili Yu Ning Sun Zhenyan Ji Jingwen Chen Jianjun Ren Xinjian | 2006 | Journal of Rare Earths2006，24，5： | 0 |
| 13 | Prevalence of familial hypercholesterolemia and its association with coronary artery disease:A Chinese cohort study显示文摘Background:Familial hypercholesterolemia(FH)is underrecognized,and its association with coronary artery disease(CAD)remains limited,especially in China.We aimed to investigate the prevalence of FH and its relationship with CAD in a large Chinese cohort.Methods:FH was defined using the Make Early Diagnosis to Prevent Early Death(MEDPED)criteria.The crude and age-sex standardized prevalence of FH were calculated based on surveys of the Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)project during 2007−2008.The associations of FH with incident CAD and its major subtypes were estimated with the cohort-stratified multivariate Cox proportional hazard models based on the data from the baseline to the last follow-up(2018−2020).Results:Among 98,885 included participants,190 participants were defined as FH.Crude and age−sex standardized prevalence and 95%confidence interval(CI)of FH were 0.19%(0.17%-0.22%)and 0.13%(0.10%-0.16%),respectively.The prevalence varied across age groups and peaked in the group of 60-<70 years(0.28%),and the peak prevalence(0.18%)in males was earlier,yet lower than the peak crude prevalence in females(0.41%).During a mean follow-up of 10.7 years,2493 cases of incident CAD were identified.After multivariate adjustment,FH patients had a 2.03-fold greater risk of developing CAD compared to non-FH participants.Conclusions:The prevalence of FH was estimated to be 0.19%in the participants,and it was associated with an elevated risk of incident CAD.Our study suggests that early screening of FH has certain public health significance for the prevention of CAD. | Xiapikatijiang Aihaiti Shufeng Chen Jianxin Li Zhennan Lin Qingmei Cui Xue Xia Fangchao Liu Chong Shen Dongsheng Hu Keyong Huang Yingxin Zhao Fanghong Lu Xiaoqing Liu Jie Cao Ling Yu Ying Li Huan Zhang Zhenyan Fu Liancheng Zhao Jianfeng Huang Dongfeng Gu Xiangfeng Lu | 2023 | Chronic Diseases and Translational Medicine2023，9，2： | 0 |
