| 2 | Reductive transformation and detoxification mechanism of 2,4-dinitrochlorobenzene in combined zero valent iron and anaerobic-aerobic process显示文摘A combined zero valent iron (ZVI) and anaerobic-aerobic process was adopted for the treatment of 2,4-dinitrochlorobenzene (DNCB)-containing wastewater. The transformation pathway, reduction of acute toxicity and enhancement of biodegradability were investigated. After pretreatment by ZVI, DNCB in wastewater could be completely converted into 2,4-diaminochlorobenzene (DACB). The ratio of BOD5/COD increased from 0.005±0.001 to 0.168±0.007, while EC 50, 48 hr (V/V) increased from 0.65% to 5.20%, indicating the enhancement of biodegradability and reduction of acute toxicity with the pretreatment by ZVI. DACB was further dechlorinated to m-phenylenediamine during the anaerobic process using methanol as electron donor, with EC50, 48 hr increasing from 5.20% to 48.2%. After the subsequent anaerobic-aerobic process, m-phenylenediamine was degraded completely, with effluent COD of 67.5±10.8 mg/L. This effluent of the subsequent anaerobic-aerobic process was not toxic to zebrafish. The combined ZVI and anaerobic-aerobic process offers bright prospects for the treatment of chlorinated nitroaromatic compound-containing wastewater. | Jinyou Shen Zongyuan Zhou Changjin OU Xiuyun Sun Jiansheng Li Weiqing Han Lin Zhou Lianjun Wang | 2012 | Journal of Environmental Sciences2012,24,11: | 4 |
| 3 | Hydrogen production from ammonia decomposition over Ni/CeO_(2) catalyst:Effect of CeO_(2) morphology显示文摘Ammonia(NH_(3)) decomposition to release CO_x-free hydrogen(H_(2)) over non-noble catalysts has gained increasing attention.In this study,three nanostructured CeO_(2) with different morphologies,viz.rod(R).sphere(Sph),and spindle(Spi),were fabricated and served as supports for Ni/CeO_(2) catalyst.The CeO_(2)supports are different in particle sizes,specific surface area and porosity,resulting in the formation of Ni nanoparticles with distinguished sizes and dispersions.The surface properties of the Ni/CeO_(2) catalysts are not only distinct but also influential,affecting the adsorption and desorption of NH_(3),N_(2),and/or H_(2)molecules.The Ni/CeO_(2)-R catalyst shows superior catalytic activity compared to the other two,owing to its smaller Ni crystallite size and larger BET surface area.The most abundant strong basic sites are observed for Ni/CeO_(2)-Spi catalyst based on its exposed CeO_(2)(110) planes,which facilitates the donation of electrons to the Ni particles,benefiting the associative desorption of N atoms.Thus,Ni/CeO_(2)-Spi shows higher catalytic activity than Ni/CeO_(2)-Sph,despite their almost identical Ni crystallite sizes. | Chongqi Chen Xiaoshuang Fan Chen Zhou Li Lin Yu Luo Chaktong Au Guohui Cai Xiuyun Wang Lilong Jiang | 2023 | Journal of Rare Earths2023,41,7: | 3 |
| 4 | Improving the ammonia synthesis activity of Ru/CeO_(2) through enhancement of the metal–support interaction显示文摘The metal–support interactions induced by high-temperature hydrogen reduction have a strong influence on the catalytic performance of ceria-supported Ru catalysts. However, the appearance of the strong metal–support interaction leads to covering of the Ru species by Ce suboxides, which is detrimental to the ammonia synthesis reaction that requires metallic species as active sites. In the present work, the interaction between Ru and ceria in the Ru/CeO_(2) catalyst was induced by NaBH_(4) treatment. NaBH_(4) treatment enhanced the fraction of metallic Ru, proportion of Ce^(3+), content of exposed Ru species, and amount of surface oxygen species. As a result, a larger amount of hydrogen species would desorb by the H_(2)-formation pathway and the strength of hydrogen adsorption would be weaker, weakening the inhibition effect of the hydrogen species on ammonia synthesis. In addition, the strong electronic metal–support interaction aids in nitrogen dissociation. Consequently, Ru/CeO_(2) with NaBH_(4) treatment showed higher ammonia synthesis rates than that with only hydrogen reduction. | Chunyan Li Yuying Shi Zecheng Zhang Jun Ni Xiuyun Wang Jianxin Lin Bingyu Lin Lilong Jiang | 2021 | Journal of Energy Chemistry2021,30,9: | 2 |

| 6 | Effect of Low Temperature on Germination Characteristics of Rice Cultivars显示文摘The effects of low temperature on germination characteristics of rice seeds were studied,using three rice varieties as materials.The results showed that the germination rate,germination energy,germination index,vigor index,shoot length and root length all reduced with the decrease of temperature.When the treatment temperature was 10 ℃,whether or not cold-resistant varieties,the values of all parameters showed an extremely significant difference from the control's.When the stress temperature was 15 ℃,compared with the normal condition,the parameter values of the non-tolerant variety( Changbai 9) had an extremely significant difference and the germination rate,germination potential,seedling length and root length of two cold-tolerance varieties( Jisheng 202 and Tongjing 9) had little difference from the control.Therefore,the above four indicators at 15 ℃ can be considered as the evaluation indices of cold tolerance at early stage. | Yadong ZHAO Dianfa ZHOU Xiuyun LIN Qiang SUN Pengzhi Li Ding Zaisong Jinming WANG | 2018 | Agricultural Biotechnology2018,7,6: | 1 |

| 8 | Boosting Efficient Ammonia Synthesis over Atomically Dispersed Co-Based Catalyst via the Modulation of Geometric and Electronic Structures显示文摘Ammonia(NH_(3))synthesis at mild conditions is of great significance,while the significant bottleneck of this process is the activation of N_(2) to realize the desired NH_(3) synthesis performance,which requires deep insight and rational design of active sites at the atomic level.Here,were synthesized atomically dispersed Co-based catalysts with different Co-N coordination numbers(CNs)to explore the coordination-sensitive NH_(3) synthesis reaction for the first time.Our studies showed that Co-based catalysts increased the NH_(3) synthesis rate gradually with a decrease in CN.The Co-N_(2) catalyst exhibited the highest NH_(3) synthesis rate of 85.3 mmol gCo^(−1) h^(−1) at 300℃ and 1 MPa,which outperformed most of the previously reported Co-based catalysts.Various characterizations and theoretical calculations demonstrated that atomically dispersed Co catalyst with low CN could generate more unoccupied Co 3d charges and tetrahedral cobalt(Ⅱ)sites.The unoccupied Co 3d charge,in turn,promoted the electron donation from the Co active center to the antibonding π-orbital(π*)of N_(2) and expedites N_(2) hydrogenation.Furthermore,the Co-N_(2) catalyst with more tetrahedral cobalt(II)sites could effectively facilitate the desorption of N-containing intermediate species(such as*NH_(3) and*N_(2)H_(4))to obtain a high NH_(3) synthesis rate. | Yanliang Zhou Congying Wang Xuanbei Peng Tianhua Zhang Xiuyun Wang Yafei Jiang Haifeng Qi Lirong Zheng Jianxin Lin Lilong Jiang | 2022 | CCS Chemistry2022,4,5: | 1 |

| 11 | High-performance self-organized Si nanocomposite anode for lithium-ion batteries显示文摘Silicon is being investigated extensively as an anodic material for next-generation lithium ion batteries for portable energy storage and electric vehicles.However,the large changes in volume during cycling lead to the breakdown of the conductive network in Si anodes and the formation of an unstable solid-electrolyte interface,resulting in capacity fading.Here,we demonstrate nanoparticles with a Si@Mn_(22.6)Si_(5.4)C_4@C double-shell structure and the formation of self-organized Si-Mn-C nanocomposite anodes during the lithiation/delithiation process.The anode consists of amorphous Si particles less than 10 nm in diameter and separated by an interconnected conductive/buffer network,which exhibits excellent charge transfer kinetics and charge/discharge performances.A stable specific capacity of 1100 mAh·g^(-1) at 100 mA·g^(-1) and a coulombic efficiency of 99.2%after 30 cycles are achieved.Additionally,a rate capacity of 343 mAh·g^(-1) and a coulombic efficiency of 99.4%at 12000 mA·g^(-1) are also attainable.Owing to its simplicity and applicability,this strategy for improving electrode performance paves a way for the development of high-performance Si-based anodic materials for lithium ion batteries. | Xiuyun Zhao Dingguo Xia Lin Gu Juncheng Yue Biao Li Hang Wei Huijun Yan Ruqiang Zou Yingxia Wang Xiayan Wang Ze Zhang Jixue Li | 2014 | Journal of Energy Chemistry2014,23,3: | 1 |
| 12 | Transcriptome shock in an interspecific F1 triploid hybrid of Oryza revealed by RNA sequencing显示文摘Interspecific hybridization is a driving force in evolution and speciation of higher plants. Interspecific hybridization often induces immediate and saltational changes in gene expression,a phenomenon collectively termed 'transcriptome shock'. Although transcriptome shock has been reported in various plant and animal taxa,the extent and pattern of shock-induced expression changes are often highly idiosyncratic,and hence entails additional investigations. Here,we produced a set of interspecific F_1 triploid hybrid plants between Oryza sativa,ssp. japonica(2n=2x=24,genome AA) and the tetraploid form of O. punctata(2n=4x=48,genome,BBCC),and conducted RNA-seq transcriptome profiling of the hybrids and their exact parental plants. We analyzed both homeolog expression bias and overall gene expression level difference in the hybrids relative to the in silico 'hybrids'(parental mixtures). We found that approximately 16%(2,541) of the 16,112 expressed genes in leaf tissue of the F_1 hybrids showed nonadditive expression, which were specifically enriched in photosynthesis-related pathways. Interestingly,changes in the maternal homeolog expression, including non-stochastic silencing, were the major causes for altered homeolog expression partitioning in the F_1 hybrids. Our findings have provided further insights into the transcriptome response to interspecific hybridization and heterosis. | Ying Wu Yue Sun Xutong Wang Xiuyun Lin Shuai Sun Kun Shen Jie Wang Tingting Jiang Silin Zhong Chunming Xu Bao Liu | 2016 | Journal of Integrative Plant Biology2016,58,2: | 1 |
| 13 | Effect of pore-size distribution on Ru/ZSM-5 catalyst for enhanced N2 activation to ammonia via dissociative mechanism显示文摘In the present study,a series of Ru/ZSM-5 catalysts with different pore-size distributions were prepared and investigated for NH3 synthesis.Our studies indicate that Ru/ZSM-5-Mic with micropore structure exhibits superior NH3 synthesis rate,which is much higher than those of Ru/ZSM-5-Mac(with macroporous structure)and Ru/ZSM-5-Mes(with mesoporous structure)catalysts.A series of TPD experiments demonstrate that pore-size distributions play an important role in N2 adsorption and activation over Ru/ZSM-5.Moreover,the addition of La significantly promotes the NH3 synthesis performance over Ru/ZSM-5-Mic.Additionally,in situ DRIFTS studies indicate that the main intermediate species over Ru/ZSM-5-Mic are-NH2,and most of the surface hydrogen species desorb following the H2O-formation pathway. | Jihui Cai Congying Wang Yi Liu Jun Ni Bingyu Lin Xiuyun Wang Jianxin Lin Lilong Jiang | 2020 | Journal of Rare Earths2020,38,8: | 1 |

| 17 | Genomic mosaicism due to homoeologous exchange generates extensive phenotypic diversity in nascent allopolyploids显示文摘Allopolyploidy is an important process in plant speciation,yet newly formed allopolyploid species typically suffer from extreme genetic bottlenecks.One escape from this impasse might be homoeologous meiotic pairing,during which homoeologous exchanges(HEs)generate phenotypically variable progeny.However,the immediate genome-wide patterns and resulting phenotypic diversity generated by HEs remain largely unknown.Here,we analyzed the genome composition of 202 phenotyped euploid segmental allopolyploid individuals from the fourth selfed generation following chromosomal doubling of reciprocal F1 hybrids of crosses between rice subspecies,using whole-genome sequencing.We describe rampant occurrence of HEs that,by overcoming incompatibility or conferring superiority of hetero-cytonuclear interactions,generate extensive and individualized genomic mosaicism across the analyzed tetraploids.We show that the resulting homoeolog copy number alteration in tetraploids affects known-function genes and their complex genetic interactions,in the process creating extraordinary phenotypic diversity at the population level following a single initial hybridization.Our results illuminate the immediate genomic landscapes possible in a tetraploid genomic environment,and underscore HE as an important mechanism that fuels rapid phenotypic diversification accompanying the initial stages of allopolyploid evolution. | Ying Wu Fan Lin Yao Zhou Jie Wang Shuai Sun Bin Wang Zhibin Zhang Guo Li Xiuyun Lin Xutong Wang Yue Sun Qianli Dong Chunming Xu Lei Gong Jonathan F.Wendel Zhiwu Zhang Bao Liu | 2021 | National Science Review2021,8,5: | 1 |
| 18 | Aqueous Zn^(2+)/Na^(+) dual-salt batteries with stable discharge voltage and high Coulombic efficiency by systematic electrolyte regulation显示文摘While aqueous Zn-Na hybrid batteries have garnered widespread attention because of their low cost and high safety,it is still challenging to achieve long cycle-life and stable discharge-voltage due to sluggish reaction kinetics,zinc dendrite formation,and side reactions.Herein,we design a Zn^(2+)/Na^(+) dual-salt battery,in which sodiation of the NVP cathode favors zinc intercalation under an energy threshold,leading to decoupled redox reactions on the cathode and anode.Systematic investigations of the electrolyte effects show that the ion intercalation mechanism and the kinetics in the mixture of triflate-and acetate-based electrolytes are superior to those in the common acetate-only electrolytes.As a result,we have achieved fast discharging capability,suppressed zinc dendrites,a stable discharge voltage at 1.45 V with small polarization,and nearly 100%Coulombic efficiency in the dual-salt mixture electrolyte with optimized concentration of 1 M Zn(OAc)_(2)+1 M NaCF_(3)SO_(3).This work demonstrates the importance of electrolyte regulation in aqueous dual-salt hybrid batteries for the energy storage. | Chunli Wang Lianshan Sun Maoxin Li Lin Zhou Yong Cheng Xin Ao Xiuyun Zhang Limin Wang Bingbing Tian Hong Jin Fan | 2022 | Science China Chemistry2022,65,2: | 1 |

| 20 | Target-oriented confinement of Ru-Co nanoparticles inside N-doped carbon spheres via a benzoic acid guided process for high-efficient low-temperature ammonia synthesis显示文摘Ru-based heterogeneous catalysts have been used in a wide range of important reactions.However,due to the sintering of Ru nanoparticles their practical applications are somewhat restricted.Herein,for the first time we report a new and facile strategy to confine Ru and/or Co nanoparticles(NPs) in the channels of N-doped carbon using benzoic acid to guide the deposition location of Ru.The developed catalyst with confined RuCo alloy particles exhibits high resistance against Ru sintering and displays excellent activity and long term stability for NH3 synthesis,achieving an NH3 synthesis rate of up to 18.9 mmol NH_(3) gcat^(-1)h^(-1)at 400℃,which is ca.2.25 times that of the catalyst prepared without confinement(with metal deposited on the support surface).In the latter case,there is an increase of nanoparticle size from 2.52 to 4.25 nm together with ca.48% decrease of NH_(3) synthesis rate after 68 h at 400℃.This study provides a new avenue for simple fabrication of precious-metal-based catalysts that are highly resistant against sintering,specifically suitable for low-temperature synthesis of ammonia with outstanding efficiency. | Jun Ni Zhenni Tan Qianjin Sai Jie Zhu Xiuyun Wang Bingyu Lin Jianxin Lin Chak-tong Au Lilong Jiang | 2021 | Journal of Energy Chemistry2021,30,6: | 0 |
