| 2 | Review on photocatalytic and electrocatalytic artificial nitrogen fixation for ammonia synthesis at mild conditions: Advances,challenges and perspectives显示文摘The ammonia synthesis from nitrogen and water under ambient conditions is one of the most inviting but challenging reaction routes.Although nitrogen is abundant in the atmosphere and the ammonia synthesis reaction is exothermic on the thermodynamics,the conversion of N2 to ammonia is actually hard to proceed owing to the chemical inertness and stability of N2 molecules.In industry,ammonia synthesis is carried out by the Haber-Bosch process under harsh conditions (300-500 ℃,20-30 MPa) associated with the requirement of substantial energy input and the enormous emission of greenhouse gases (e.g.,CO2).Recently,a growing number of studies on photo(electro)catalytic and electrocatalytic nitrogen reduction reaction (NRR) in aqueous solution have attracted extensive attention,which holds great promise for nitrogen fixation under room temperature and atmospheric pressure.However,the very low efficiency and ambiguous mechanism still remain as the major hurdles for the development of photochemical and electrochemical NRR systems.Here we provide an overview of the latest progresses,remaining challenges and future prospects in photocatalytic and electrocatalytic nitrogen fixation.Moreover,this review offers a helpful guidance for the reasonable design of photocatalysts and electrocatalysts towards NRR by combining theory predictions and experiment results.We hope this review can stimulate more research interests in the relatively understudied but highly promising research field of NRR. | Xiaolan Xue Renpeng Chen Changzeng Yan Peiyang Zhao Yi Hu Wenjun Zhang Songyuan Yang Zhong Jin | 2019 | Nano Research2019，12，6： | 20 |
| 3 | Geodynamic Background of Intracontinental Cenozoic Alkaline Volcanic Rocks in Laojiezi, Western Yangtze Craton: Constraints from Sr-Nd-Hf-O Isotopes显示文摘The Laojiezi alkaline volcanic rocks, which are located in the intraplate region of the Yangtze craton, coincide with the formation of the Jinshajiang-Ailaoshan-Red River alkaline rock belt. Although this belt has been widely studied by geologists because of its porphyry-related Pb-Ag-Au polymetallic deposit and geotectonic location, the material sources of this belt are still debate. Whole-rock analyses show that these rocks have high total alkali contents(3.73–11.08 wt%), and their aluminum saturation index(ASI) values widely vary from 0.82 to 3.07, which comprise a metaluminous-peraluminous magma series. These rocks are characterized by high K(K2 O/Na2 O>1) and low Ti and Mg contents; enrichment in large-ion lithophile elements, such as Rb, Ba, K and light rare earth elements; and depletion in high field strength elements, such as Ta, Nb, P, and Ti. These rocks exhibit moderate Eu(Eu/Eu*=0.86–1.04) and Ce(Ce/Ce*=0.63–0.96) anomalies. Their(87 Sr/86 Sr)i, εNd(t), zircon εHf(t) and δ18 O values range from 0.70839 to 0.71013, from-10.16 to-12.45, from-19.6 to-5.8, and from 5.69‰ to 8.54‰, respectively, and their Nd and Hf two-stage model ages(TDM2) are 1.67–1.86 Ga and 1.27–2.02 Ga, respectively. These data reflect the primary partial melting of Paleoproterozoic to Mesoproterozoic lower crust with minor residual continental lithospheric mantle and supracrustal metasediments. The lithosphere was likely thickened along the southeastern margin of the Tibetan Plateau following the Indian-Asian continentcontinent collision(65–41 Ma). During the post-collision phase(36–16 Ma), the transition from a compressional to extensional setting triggered the convective removal of the over-thickened CLM beneath the Yangtze craton, which led to the upwelling of asthenospheric materials. This process created alkali-rich and high-K magma through the partial melting of the thickened lower crust. Magma that carried Cu-Au-Pb-Ag minerals was emplaced by strike-slip motion along the E-to W-or ENE-to WSWtrending tectonically weak zone, finally forming an alkaline porphyry Cu-Au-Pb-Ag polymetallic deposit. | YAN Qinggao JIANG Xiaojun LI Chao ZHOU Limin WANG Zhongqiang Sultan Baig SHER QU Wenjun DU ANDao | 2018 | Acta Geologica Sinica(English Edition)2018，92，6： | 12 |
| 4 | Status of hyperhomocysteinemia in China: results from the China Stroke High-risk Population Screening Program, 2018显示文摘A nationwide survey was conducted from October 2018 to September 2019 to assess the prevalence of hyperhomocysteinemia(Hhcy)and its influencing factors in China.A standardized questionnaire was used to collect information.Hhcy was defined as the level of serum homocysteine(HCY)≥15.0µmol/L.The H-type hypertension(HHYP)was defined as hypertension with an elevated serum HCY(≥15.0µmol/L).Finally,110551 residents≥40 years of age from 31 provinces in the mainland of China were included.Overall,the median serum HCY level was 10.9µmol/L(interquartile range 7.9–15.1).A total of 28633 participants(25.9%)were defined as Hhcy.The Hhcy prevalence ranged from 7.9%in Shanghai to 56.8%in Tianjin.The data showed that serum HCY levels were associated with age,male gender,cigarette smoking,hypertension,diabetes,ethnicity,endurance in exercise(inverse),and fruit and vegetable intake(inverse).In addition,15486 participants were defined as HHYP,and the rate was 14.0%.HHYP was an independent predictor of stroke with an adjusted odds ratio of 1.752(95%CI 1.338–2.105).The geographical distribution pattern of the Hhcy epidemic reflects dynamic differences,and national strategies should be carried out to further improve the care of patients with Hhcy across China. | Wenjun Tu Feng Yan Baohua Chao Xunming Ji Longde Wang | 2021 | Frontiers of Medicine2021，15，6： | 12 |
| 5 | Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells. | Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang | 2017 | Nano Research2017，10，9： | 9 |
| 6 | Hierarchical space–time block codes signals classification using higher order cumulants显示文摘An efficient method for blind classification of space–time block codes(STBCs) based on fourth-order cumulants is proposed for a single receiver antenna.This paper presents a model of received STBCs signals in multiple input single output(MISO) communication systems and applies the characteristics of coding matrices to derive analytical expressions for the fourth-order cumulants to be used as the basis of an algorithm.The fourth-order cumulants at various delay vectors present non-null values that depend on the transmitted STBCs.Tests of nullity are accomplished by hypothesis testing.The proposed algorithm avoids the need for a priori information of modulation scheme,channel coefficients,and noise power.Consequently,it is well suited for non-cooperative scenarios.Simulations show that this method performs well even at low signal-to-noise ratios(SNRs). | Ling Qing Zhang Limin Yan Wenjun Kong Dongming | 2016 | Chinese Journal of Aeronautics2016，29，3： | 9 |
| 7 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 8 | Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes. | Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li | 2020 | Cell Research2020，30，2： | 7 |
| 9 | The ninth-mode sectorial oscillation of acoustically levitated drops显示文摘We report on the ninth-mode sectorial oscillation of acoustically levitated drops excited by actively modulating sound pressure. A numerical computation based on the level set method was performed to model drop shape evolution by solving an incompressible two-phase flow problem. The calculated shapes of the oscillating drop are in good agreement with experimental observations. The relationship between the oscillation frequency and parameters describing the flattened drops is studied both experimentally and numerically. The frequency of the ninth-mode sectorial oscillation decreases with increasing equatorial radius and can be well-described by a modified Rayleigh equation. | YAN ZhenLin XIE WenJun GENG DeLu WEI BingBo | 2011 | Chinese Science Bulletin2011，56，31： | 5 |
| 10 | A Polysaccharide-Degrading Marine Bacterium Flammeovirga sp.MY04 and Its Extracellular Agarase System显示文摘Bacteria of the genus Flammeovirga can digest complex polysaccharides (CPs), but no details have been reported regarding the CP depolymerases of these bacteria. MY04, an agarolytic marine bacterium isolated from coastal sediments, has been identified as a new member of the genus Flammeovirga. The MY04 strain is able to utilize multiple CPs as a sole carbon source and grows well on agarose, mannan, or xylan. This strain produces high concentrations of extracellular proteins (490 mg L-1 ± 18.2 mg L-1 liquid culture) that exhibit efficient and extensive degradation activities on various polysaccharides, especially agarose. These proteins have an activity of 310 U mg-1 ± 9.6 U mg-1 proteins. The extracellular agarase system (EAS) in the crude extracellular enzymes contains at least four agarose depolymerases, which are with molecular masses of approximately 30-70 kDa. The EAS is stable at a wide range of pH values (6.0-11.0), temperatures (0-50℃), and sodium chloride (NaCl) concentrations (0- 0.9 mol L-1). Two major degradation products generated from agarose by the EAS are identified to be neoagarotetraose and neoagarohexaose, suggesting that β-agarases are the major constituents of the MY04 EAS. These results suggest that the Flammeovirga strain MY04 and its polysac-charide-degradation system hold great promise in industrial applications. | HAN Wenjun GU Jingyan YAN Qiujie LI Jungang WU Zhihong GU Qianqun LI Yuezhong | 2012 | Journal of Ocean University of China2012，11，3： | 5 |

| 20 | Analysis of GNSS radio occultation data from satellite ZH-01显示文摘The electromagnetic satellite Zhangheng 01(ZH-01) was successfully launched on February 2, 2018. The GNSS Radio Occultation(GRO) receiver on board the satellite is able to observe the occultation events of GPS and BeiDou navigation satellites. We analyzed the data acquired during the in-orbit testing period. We concludes that the GRO ionosphere inversion results are reasonable,the trend is correct, the satellite can observe about 600 ionosphere occultation events each day. The global coverage of more than 30000 consecutive GRO events in more than two months were analyzed and compared with COSMIC observations: both the GRO and COSMIC occultation can realize global coverage: the Nm F2 and Hm F2 global distributions are similar and change obviously with latitude. We used three digisondes at different latitudes to analyze and compare the spatio-temporally consistent GRO data: the RMSE of GRO Nm F2 relative to digisonde is better than 9.41%, the correlation coefficient is better than 0.8682: the relative RMSE of Hm F2 is better than 7.80% and the correlation coefficient is better than 0.7066. | Yan Cheng Jian Lin XuHui Shen Xiang Wan XinXing Li WenJun Wang | 2018 | Earth and Planetary Physics2018，2，6： | 2 |
