| 1 | Theory and Practice of Oxide Inclusion Composition and Morphology Control in Spring Steel Production显示文摘In order to control the composition, morphology and size distribution of oxide inclusions in spring steel, the relationship between the content or activity of aluminum and calcium in molten steel and compositions of oxide inclusion precipitated at different temperatures was determined based on thermodynamic equilibrium for spring steel 60Si2MnA, and has been verified by practice. The size distribution of non-metallic inclusions electrolytically extracted from specimens of hot rolled spring steel was determined by image analyzer. The results show that there are a great deal of large inclusions in spring steel produced by the conventional process, and the quantity and the size of large inclusions in spring steel produced by new process are largely reduced. As a result, the fatigue properties of the spring steel produced by new process are highly improved, and the ratio of σ-1/σb is raised from 0.451 to 0.468. | XUEZheng-liang LIZheng-bang ZHANGJia-wen YANGWu GANChao-fu WANGYu | 2003 | Journal of Iron and Steel Research(International)2003，10，2： | 5 |
| 2 | Exogenous rare earth element-yttrium deteriorated soil microbial community structure显示文摘In this study, we selected yttrium as the representative of REEs to investigate the impacts of exogenous yttrium on soil physicochemical properties and microbiota. The results showed that exogenous yttrium has no significant effect on soil physical properties but a significantly negative impact on soil chemical properties. The results of high-throughput sequencing demonstrate that exogenous yttrium significantly decreases the number of OTUs, ACE, Chao 1, and Shannon indices while increases the Simpson index(P < 0.05), indicating the low soil microbial diversity. The relative abundances of soil microbes are significantly changed at phylum and genus level. Principal component analysis(PCA) showed the significant difference of microbial community between yttrium treatments(YCl_3-250 and YCl_3-500) and non-yttrium treatment(CK) and the similarity of that between YCl_3-250 and YCI_3-500. Proteobacteria and Bacteroidetes are found to be the most tolerant phyla to exogenous yttrium while Verrucomicrobia the most sensitive phylum. Redundancy analysis(RDA) results suggest that exogenous yttrium affects soil microbiota only through changing the soil chemical properties but not soil physical properties, and C/N ratio is the key environmental factor. | Caigui Luo Yangwu Deng Jian Liang Sipin Zhu Zhenya Wei Xiaobin Guo Xianping Luo | 2018 | Journal of Rare Earths2018，36，4： | 5 |
| 3 | Determination of Heroin Based on Analyte Pulse Perturbation to an Oscillating Chemical Reaction显示文摘A new analytical method is proposed for the determination of heroin based on a sequential perturbation caused by trace amounts of heroin in the Cu(Ⅱ)-catalyzed oscillating reaction between hydrogen peroxide and sodium thiocyanate in an alkaline medium with the aid of a continuous-flow stirred tank reactor(CSTR). The method relies on the linear relationship between the change in oscillation period of the system and the concentration of heroin, with a detecting limit of 4.0×10-7 mol/L. The calibration curve fits a linear equation very well when the concentration of heroin is in the range of 2.0×10-61.2×10-5 mol/L(r=0.9971). This method features good precision(RSD=0.98%). The influences of temperature, injection point, flow rate and reaction variables on the oscillation period were investigated in detail and a possible mechanism of the performance of heroin in the Cu(Ⅱ)-catalyzed oscillating reaction system is also discussed. The proposed method opens a new avenue for the determination of heroin. | RENJie GAOJin-zhang Suo-nan ZHAOGuo-hu YANGWu LüDong-yu SUNKan-jun LIChong-yang | 2004 | Chemical Research in Chinese Universities2004，20，5： | 4 |
| 4 | Magnetic plasmon resonances in nanostructured topological insulators for strongly enhanced light-MoS_(2) interactions显示文摘Magnetic resonances not only play crucial roles in artificial magnetic materials but also offer a promising way for light control and interaction with matter.Recently,magnetic resonance effects have attracted special attention in plasmonic systems for overcoming magnetic response saturation at high frequencies and realizing high-performance optical functionalities.As novel states of matter,topological insulators(TIs)present topologically protected conducting surfaces and insulating bulks in a broad optical range,providing new building blocks for plasmonics.However,until now,high-frequency(e.g.visible range)magnetic resonances and related applications have not been demonstrated in TI systems.Herein,we report for the first time,to our knowledge,a kind of visible range magnetic plasmon resonances(MPRs)in TI structures composed of nanofabricated Sb_(2)Te_(3) nanogrooves.The experimental results show that the MPR response can be tailored by adjusting the nanogroove height,width,and pitch,which agrees well with the simulations and theoretical calculations.Moreover,we innovatively integrated monolayer MoS_(2) onto a TI nanostructure and observed strongly reinforced light-MoS_(2) interactions induced by a significant MPR-induced electric field enhancement,remarkable compared with TI-based electric plasmon resonances(EPRs).The MoS_(2) photoluminescence can be flexibly tuned by controlling the incident light polarization.These results enrich TI optical physics and applications in highly efficient optical functionalities as well as artificial magnetic materials at high frequencies. | Hua Lu Zengji Yue Yangwu Li Yinan Zhang Mingwen Zhang Wei Zeng Xuetao Gan Dong Mao Fajun Xiao Ting Mei Weiyao Zhao Xiaolin Wang Min Gu Jianlin Zhao | 2020 | Light(Science & Applications)2020，9，1： | 3 |
| 5 | A Multifunctional Anti-Proton Electrolyte for High-Rate and Super-Stable Aqueous Zn-Vanadium Oxide Battery显示文摘Large volumetric expansion of cathode hosts and sluggish transport kinetics in the cathode–electrolyte interface,as well as dendrite growth and hydrogen evolution at Zn anode side are considered as the system problems that cause the electrochemical failure of aqueous Zn-vanadium oxide battery.In this work,a multifunctional anti-proton electrolyte was proposed to synchronously solve all those issues.Theoretical and experimental studies confirm that PEG 400 additive can regulate the Zn^(2+) solvation structure and inhibit the ionization of free water molecules of the electrolyte.Then,smaller lattice expansion of vanadium oxide hosts and less associated by-product formation can be realized by using such electrolyte.Besides,such electrolyte is also beneficial to guide the uniform Zn deposition and suppress the side reaction of hydrogen evolution.Owing to the integrated synergetic modifica-tion,a high-rate and ultrastable aqueous Zn-V_(2)O_(3)/C battery can be constructed,which can remain a specific capacity of 222.8 m Ah g^(-1)after 6000 cycles at 5 A g^(-1),and 121.8 m Ah g^(-1) even after 18,000 cycles at 20 A g^(-1),respectively.Such“all-in-one”solution based on the electrolyte design provides a new strategy for developing high-performance aqueous Zn-ion battery. | Yangwu Chen Dingtao Ma Kefeng Ouyang Ming Yang Sicheng Shen Yanyi Wang Hongwei Mi Lingna Sun Chuanxin He Peixin Zhang | 2022 | Nano-Micro Letters2022，14，9： | 3 |
| 6 | Degradation of crystal violet using nanometer TiO_2 under the synergistic action of H_2O_2 and ultrasonic wave显示文摘TiO2 nanoparticles with different phases are prepared by hydrolysis of titanium tetrabutoxide in the presence of HCl. The composition and microstructure of the resulting samples are studied by XRD and TEM. These results show that the range of particle size of TiO2 is from 20 to 30 nm. The mechanism of TiO2 photocatalysis reaction has been discussed extensively. Photocatalytic activities of nanometer TiO2 are also evaluated by degradation of the crystal violet solution. Experimental results indicate that the synergistic action of H2O2 and ultrasonic wave greatly enhances photo-catalytic reaction of TiO2. | GUOXiaojun YUANLi QIYouli LIXien YANGWu GAOJinzhang | 2004 | Rare Metals2004，23，4： | 2 |

| 16 | Different J-Type Aggregates of meso-Tetrakis (4-hydroxyphenyl) porphyrin (H_(2)THPP) Formed in Different Solvents显示文摘The aggregation of meso-tetrakis(4-hydroxyphenyl)porphyrin (H2THPP) in dimethyl- formamide (DMF)-water solution and in DMF-chloroform solution was studied by UV-vis absorption spectroscopy. The red shift of Soret band indicates the formation of J-type aggregates of H2THPP in these two solutions. However, different shift extent of Soret band, 12 nm in DMF-water solution and 32 nm in DMF-chloroform solution, implies structural difference between these two J-type aggregates. The hydrogen bond between hydroxyl group and N-H bonds in porphyrin ring is thought as the main cause to the formation of J-type aggregate in DMF- chloroform solution, whereas the π?σ interaction between two adjacent porphyrin cores is thought as the main cause of the formation of J-type aggregate in DMF-water | YingHuiZHANG YangWU | 2005 | Chinese Chemical Letters2005，16，4： | 0 |
| 17 | Microplastics affect activity and spatial distribution of C,N, and P hydrolases in rice rhizosphere显示文摘Microplastics provide a new ecological niche for microorganisms,and the accumulation levels of microplastics(MPs)in terrestrial ecosystems are higher than those in marine ecosystems.Here,we applied the zymography to investigate how MPs–polyethylene[PE],and polyvinyl chloride[PVC])at two levels(0.01%and 1%soil weight)impacted the spatial distribution of soil hydrolases,nutrient availability,and rice growth in paddy soil.MPs increased the above-ground biomass by 13.0%–15.5%and decreased the below-ground biomass by 8.0%–15.1%.Addition of 0.01%and 1%MPs reduced soil NH4+content by 18.3%–63.2%and 52.2%–80.2%,respectively.The average activities of N-and P-hydrolases increased by 0.8%–4.8%and 1.9%–6.3%with addition of MPs,respectively.The nutrient uptake by rice plants and the enzyme activities in hotspots increased with MP content in soil.The accumulation of MPs in paddy soil could provide an ecological niche that facilitates microbial survival,alters the spatial distribution of soil hydrolases,and decreases nutrient availability. | Yaoyao Tong Jina Ding Mouliang Xiao Muhammad Shahbaz Zhenke Zhu Ming Chen Yakov Kuzyakov Yangwu Deng Jianping Chen Tida Ge | 2023 | Soil Ecology Letters2023，5，3： | 0 |
| 18 | Strain of 2D materials via substrate engineering显示文摘Two-dimensional(2D)materials have received extensive attention in the fields of electronics,optoelectronics,and magnetic devices attributed to their unique electronic structures and physical properties.The application of strain is a simple and effective strategy to change the lattice structure of 2D materials thus modulating their physical properties,which further facilitate their applications in carrier mobility transistor,magnetic sensor,single-photon emitter etc.In this short review,we focus on the strain applied via substrate engineering.Firstly,the relationship between the strain and physical properties has been summarized.Secondly,the methods for achieving substrate engineering-induced strain have been demonstrated.Finally,the latest applications of strained 2D materials have been introduced.In addition,the future challenges and development prospects of strain-modulated 2D materials have also been proposed. | Yangwu Wu Lu Wang Huimin Li Qizhi Dong Song Liu | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
| 19 | Evaluation of the stability of shortcut nitrification-denitrification process based on online specific oxygen uptake rate monitoring显示文摘Shortcut nitrification-denitrification(SCND)is widely concerned because of its low energy consumption and high nitrogen removal efficiency.However,the current difficulty lies in the stable maintenance of SCND performance,which leads to the challenge of large-scale application of this new denitrification technology.In this study,the nitrogen removal pathway from complete nitrification-denitrification(CND)to SCND was rapidly realized under high free ammonia(FA),high pH and low dissolved oxygen(DO)conditions.The variations of specific oxygen uptake rate(SOUR)of activated sludge in both processes were investigated by an online SOUR monitoring device.Different curves of SOUR from CND to SCND process were observed,and the ammonia peak obtained based on SOUR monitoring could be used to control aeration time accurately in SCND process.Accordingly,the SOUR ratio of ammonia oxidizing bacteria(AOB)to nitrite oxidizing bacteria(NOB)(SOURAOB/SOURNOB)was increased from 1.40 to 2.93.16S rRNA Miseq high throughput sequencing revealed the dynamics of AOB and NOB,and the ratio of relative abundance(AOB/NOB)was increased from 1.03 to 3.12.Besides,SOURAOB/SOURNOB displayed significant correlations to ammonia removal rate(P<0.05),ammonia oxidation rate/nitrite oxidation rate(P<0.05),nitrite accumulation rate(P<0.05)and the relative abundance of AOB/NOB(P<0.05).Thus,a strategy for evaluation the SCND process stability based on online SOUR monitoring is proposed,which provides a theoretical basis for optimizing the SCND performance. | Zhouliang Tan Yue Guan Yajun Luo Lin Wang Houzhen Zhou Chong Yang Dan Meng Yangwu Chen | 2023 | Chinese Chemical Letters2023，34，8： | 0 |
| 20 | Systemic and single cell level responses to 1 nm size biomaterials demonstrate distinct biological effects revealed by multi-omics atlas显示文摘Although ultra-small nanoclusters(USNCs,<2 nm)have immense application capabilities in biomedicine,the investigation on body-wide organ responses towards USNCs is scant.Here,applying a novel strategy of single-cell mass cytometry combined with Nano Genome Atlas of multi-tissues,we systematically evaluate the interactions between the host and calcium phosphate(CaP)USNCs at the organism level.Combining single-cell mass cytometry,and magnetic luminex assay results,we identify dynamic immune responses to CaP USNCs at the single cell resolution.The innate immune is initially activated and followed by adaptive immune activation,as evidenced by dynamic immune cells proportions.Furthermore,using Nano Genome Atlas of multi-tissues,we uncover CaP USNCs induce stronger activation of the immune responses in the cartilage and subchondral bone among the five local tissues while promote metabolic activities in the liver and kidney.Moreover,based on the immunological response profiles,histological evaluation of major organs and local tissue,and a body-wide transcriptomics,we demonstrate that CaP USNCs are not more hazardous than the Food and Drug Administration-approved CaP nanoparticles after 14 days of injection.Our findings provide valuable information on the future clinical applications of USNCs and introduce an innovative strategy to decipher the whole body response to implants. | Tao Zhang Tingyun Lei Ruojin Yan Bo Zhou Chunmei Fan Yanyan Zhao Shasha Yao Haihua Pan Yangwu Chen Bingbing Wu Yuwei Yang Lijuan Hu Shen Gu Xiaoyi Chen Fangyuan Bao Yu Li Hanqi Xie Ruikang Tang Xiao Chen Zi Yin | 2022 | Bioactive Materials2022，7，12： | 0 |
