| 1 | Plant diversity reduces the effect of multiple heavy metal pollution on soil enzyme activities and microbial community structure显示文摘It is unclear whether certain plant species and plant diversity could reduce the impacts of multiple heavy metal pollution on soil microbial structure and soil enzyme activities. Random amplified polymorphic DNA (RAPD) was used to analyze the genetic diversity and microbial similarity in planted and unplanted soil under combined cadmium (Cd) and lead (Pb) pollution. A metal hyper- accumulator, Brassica juncea, and a common plant, Festuca arundinacea Schreb, were used in this research. The results showed that microorganism quantity in planted soil significantly increased, compared with that in unplanted soil with Cd and Pb pollution. The order of microbial community sensitivity in response to Cd and Pb stress was as follows: actinomycetes 〉 bacteria 〉 fungi. Respiration, phosphatase, urease and dehydrogenase activity were significantly inhibited due to Cd and Pb stress. Compared with unplanted soil, planted soils have frequently been reported to have higher rates of microbial activity due to the presence of additional surfaces for microbial colonization and organic compounds released by the plant roots. Two coexisting plants could increase microbe population and the activity of phosphatases, dehydrogenases and, in particular, ureases. Soil enzyme activity was higher in B. juncea phytoremediated soil than in F. arundinacea planted soil in this study. Heavy metal pollution decreased the richness of the soil microbial community, but plant diversity increased DNA sequence diversity and maintained DNA sequence diversity at highlevels. The genetic polymorphism under heavy metal stress was higher in B. juncea phytoremediated soil than in F. arundinacea planted soil. | Yang GAO Chiyuan MIAO Jun XIA Liang MAO Yafeng WANG Pei ZHOU | 2012 | Frontiers of Environmental Science & Engineering2012，6，2： | 14 |
| 2 | Surrounding rock control mechanism of deep coal roadways and its application显示文摘Aiming at the surrounding rock control problem of mining and preparation entries in Xingdong mine with large mining depth, and the comprehensive control countermeasures including high pre-stress cable truss system, this study put forward powerful anchor support system and anchor cable adaption technology to surrounding rock deformation. Furthermore, the control measures possess the supporting performance with ‘‘primary rigid-following flexible-new rigid, and primary resistance-following yield-new resistance'', which suits deep roadway surrounding rock control. The mechanical model of truss anchor supporting roof beams was established, and the inverted arch deflection produced by the cable pre-stress with stress increment effect and roof beam deflection were obtained. And then the system working mechanism was illustrated. Finally, the surrounding rock support parameters were determined by means of comprehensive methods, and put into practice. The results show that surrounding rock deformation realized secondary stability after three months. The roadway sides convergence value was less than 245mm, and roof subsidence was less than 124mm. In addition, there was no expansion and renovation during service period. | Xie Shengrong Li Erpeng Li Shijun Wang Jinguang He Chongchong Yang Yafeng | 2015 | International Journal of Mining Science and Technology2015，25，3： | 10 |

| 4 | Improving in vitro and in vivo corrosion resistance and biocompatibility of Mg-1Zn-1Sn alloys by microalloying with Sr显示文摘Magnesium(Mg)and its alloys have attracted attention as potential biodegradable materials in orthopedics due to their mechanical and physical properties,which are compatible with those of human bone.However,the effect of the mismatch between the rapid material degradation and fracture healing caused by the adverse effect of hydrogen(H2),which is generated during degradation,on surrounding bone tissue has severely restricted the application of Mg and its alloys.Thus,the development of new Mg alloys to achieve ideal degradation rates,H2 evolution and mechanical properties is necessary.Herein,a novel Mg-1Zn-1Sn-xSr(x=0,0.2,0.4,and 0.6 wt%)quaternary alloy was developed,and the microstructure,mechanical properties,corrosion behavior and biocompatibility in vitro/vivo were investigated.The results demonstrated that a minor amount of strontium(Sr)(0.2 wt%)enhanced the corrosion resistance and mechanical properties of Mg-1Zn-1Sn alloy through grain refinement and second phase strengthening.Simultaneously,due to the high hydrogen overpotential of tin(Sn),the H2 release of the alloys was significantly reduced.Furthermore,Sr-containing Mg-1Zn-1Sn-based alloys significantly enhanced the viability,adhesion and spreading of MC3T3-E1 cells in vitro due to their unique biological activity and the ability to spontaneously form a network structure layer with micro/nanotopography.A low corrosion rate and improved biocompatibility were also maintained in a rat subcutaneous implantation model.However,excessive Sr(>0.2 wt%)led to a microgalvanic reaction and accelerated corrosion and H2 evolution.Considering the corrosion resistance,H2 evolution,mechanical properties and biocompatibility in vitro and in vivo,Mg-1Zn-1Sn-0.2Sr alloy has tremendous potential for clinical applications. | Yafeng Wen Qingshan Liu Jingfeng Wang Qiming Yang Weikang Zhao Bo Qiao Yuling Li Dianming Jiang | 2021 | Bioactive Materials2021，6，12： | 3 |
| 5 | Blockchain-based data transmission control for Tactical Data Link显示文摘Tactical Data Link(TDL)is a communication system that utilizes a particular message format and a protocol to transmit data via wireless channels in an instant,automatic,and secure way.So far,TDL has shown its excellence in military applications.Current TDL adopts a distributed architecture to enhance anti-destruction capacity.However,It still faces a problem of data inconsistency and thus cannot well support cooperation across multiple militarily domains.To tackle this problem,we propose to leverage blockchain to build an automatic and adaptive data transmission control scheme for TDL.It achieves automatic data transmission and realizes information consistency among different TDL entities.Besides,applying smart contracts based on blockchain further enables adjusting data transmission policies automatically.Security analysis and experimental results based on simulations illustrate the effectiveness and efficiency of our proposed scheme. | Wei Feng Yafeng Li Xuetao Yang Zheng Yan Liang Chen | 2021 | Digital Communications and Networks2021，7，3： | 3 |

| 7 | Fate of river‐transported carbon in china:implications for carbon cycling in coastal ecosystems显示文摘Rivers play an important role in carbon(C)exchange between terrestrial and oceanic water bodies and the atmosphere.The aim of this study was to systematically quantify fluxes in riverine C export and C exchange in the air-sea interface of marine ecosystems in China.Results show that annual C transport from rivers to coastal ecosystems in China can reach up to 64.35 TgC,which accounts for approximately 4.8%-8.1%of global C transport from river systems.In the Bohai Sea,particulate inorganic carbon is the main form of C influx,and it can reach up to 20.79 TgC/yr.Conversely,dissolved inorganic carbon is the main form of C influx into the East China Sea,and it can reach up to 10.52 TgC/yr,which is 42.6%of the total annual C imported into the East China Sea.China’s marine ecosystems including the Yellow Sea,the Bohai Sea,the East China Sea,and the South China Sea can absorb 65.06 TgC/yr from the atmosphere. | Yang Gao Tiantian Yang Yafeng Wang Guirui Yu | 2017 | Ecosystem Health and Sustainability2017，3，3： | 2 |
| 8 | Role of surface roughness in the magnesite flotation and its mechanism显示文摘Surface roughness has a significant influence on mineral flotation.The assisting effect of surface roughness on minerals flotation is extensively investigated from its physical properties(e.g.,the existing form of asperity and its size),however,the associated effect on mineral flotation based on the differences in surface chemical property caused by surface roughness has been rarely touched.With such a question in mind,in this study,we investigated the flotation recoveries of two batches of magnesite particles with varying degree of surface roughness produced by two different mills,and associated the flotation performances to their surface chemical properties(amount of adsorption sites for the collector)via a series of detections,including Scanning Electron Microscope-Energy Dispersive Spectrometry(SEM-EDS)observations,X-ray photoelectron spectroscopy(XPS)analysis,adsorption capacity tests,and contact angle measurements.Finally,we concluded that rougher magnesite particles could provide more active sites(Mg^(2+))for a larger capacity of sodium oleate(NaOL),thereby improving the hydrophobicity and floatability. | Zhanglei Zhu Yafeng Fu Wanzhong Yin Haoran Sun Keqiang Chen Yuan Tang Bin Yang | 2022 | Particuology2022，20，3： | 2 |

| 20 | Highly ductile hypereutectic Al-Si alloys fabricated by selective laser melting显示文摘In the endeavor to maximize the refinement effect of primary Si and alleviate the inherent brittleness of hypereutectic Al-Si alloy,the approach of coating P as a modifier on powder was adopted.The ultimate aim was to create more heterogeneous fine Al P nucleus and enhance the nucleation efficiency of primary Si on Al P to refine the coarse primary Si to nano-scale during 3D printing.In the combination of large undercooling and high density of nucleation sites,the size of primary Si was successfully refined to 200–300 nm and the divorced eutectic was also induced to modify the microstructure of matrix.In the presence of nano-scale primary Si,the melting pool boundary(MPB)feature disappeared and the fracture mechanism also changed from load transfer to interfacial fracture.Compared with the pristine alloy,the ductility was increased four times without significantly changing the ultimate tensile strength(UTS)and wear resistance.The improvement of ductility is attributed to the refinement of primary Si,the disappearance of MPB features and the formation of divorced eutectic.The optimal tensile properties were:UTS-482 MPa,yield strength-320 MPa and ductility of 8.1%at 0.05 wt.%P.These are comparable to those for high-strength Al alloys. | Yafeng Yang Kang Geng Shaofu Li Michael Bermingham R.D.K.Misra | 2022 | Journal of Materials Science & Technology2022，，15： | 1 |
