| 1 | A novel aminated polymeric adsorbent for removing refractory dissolved organic matter from landfill leachate treatment plant显示文摘Refractory dissolved organic matter (DOM) from landfill leachate treatment plant was with high dissolved organic carbon (DOC) content. An aminated polymeric adsorbent NDA-8 with tertiary amino groups and sufficient mesopore was synthesized, which exhibited high adsorption capacity to the DOM (raw water after coagulation). Resin NDA-8 performed better in the uptake of the DOM than resin DAX-8 and A100. Electrostatic attraction was considered as the decisive interaction between the adsorbent and adsorbate. Special attention was paid to the correlation between porous structure and adsorption capacity. The mesopore of NDA-8 played a crucial role during uptake of the DOM. In general, resin in chloride form performed a higher removal rate of DOC. According to the column adsorption test, total adsorption capacity of NDA-8 was calculated to 52.28 mg DOC/mL wet resin. 0.2 mol/L sodium hydroxide solution could regenerate the adsorbent efficiently. | ZHANG Long, LI Aimin, WANG Jinnan, LU Yufei, ZHOU Youdong State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing 210093, China. | 2009 | Journal of Environmental Sciences2009，21，8： | 5 |
| 2 | Correlation Between Dynamic Compressive Strength and Fracture Behaviors of Bulk Metallic Glasses显示文摘The mechanical behaviors of Zr43.5Cu43.5Ni4Al8Nb1,Zr55.4Cu31.6Ni4Al8Nb1,Ti32.8Zr30.2Ni5.3Cu9Be22.7(at.%)metallic glass at different strain rates were studied.For all the present alloys,the dispersion over 700 MPa was observed on the strength in the repeated dynamic compressions,which was much stronger than that of the quasi-static compressive strength.Such the dispersion of the dynamic compressive strength was well correlated with the corresponding fracture behaviors.The area of fracture surface was calculated and also showed a strong dispersion for all the fractured specimens tested at the strain rate of 500 s^-1 and 1000 s^-1.All the specimens showed a linear relationship between the square of dynamic compressive strength and the area of fracture surface in the dynamic compression tests.This phenomenon was mainly thought to be related to the difference of mean initial free volume concentration of different samples,stress concentration caused by the split Hopkinson pressure bar experimental setup and high sensitivity of defects under dynamic deformation.These findings were beneficial to deeply understand the effect of strain rate on the mechanical properties of the metallic glass. | Wenqing Li Zhengwang Zhu Guojie Li Long Zhang Zhengkun Li Huameng Fu Hongwei Zhang Hong Li Aimin Wang Haifeng Zhang | 2020 | Acta Metallurgica Sinica(English Letters)2020，33，10： | 2 |

| 4 | The effect of continuous Ni(Ⅱ) exposure on the organic degradation and soluble microbial product(SMP) formation in two-phase anaerobic reactor显示文摘A two-phase anaerobic reactor fed with glucose substrate(3 g chemical oxygen demand(COD)/L) was used to investigate the effects of toxic metals on the degradation of organics and the soluble microbial product(SMP) formation. Low concentrations of Ni(II)(5 and10 mg/L) promoted the acid phase, whereas high concentrations(15, 20, and 25 mg/L)exhibited an inhibitory effect on, but did not alter the fermentative method, which mainly involved the fermentation of propionic acid. The methanogenic microorganism exhibited a strong capability adapting constantly increased Ni(II) levels. The acid phase was an accumulation stage of SMP. In the absence of Ni(II), the high-molecular-weight material in the effluent SMP mainly contained polysaccharide, tryptophan, and casein. Methanogens metabolized most of the polysaccharide, the whole tryptophan content, and part of the casein, leading to the presence of humic acid and protein in effluent. After Ni(II) dosage, the protein and polysaccharide of the acid phase increased, and tryptophan changed, while casein remained stable. More protein than polysaccharide was produced, suggesting the prominent function of protein when addressing the negative effect of toxic metals. The analysis of DNA confirmed the change of bacterial activity. | Wei Wu Tengteng Duan Hailiang Song Yan Li Ang Yu Long Zhang Aimin Li | 2015 | Journal of Environmental Sciences2015，27，7： | 2 |

| 8 | Corrosion mechanisms of Zr-based bulk metallic glass in NaF and NaCl solutions显示文摘So far,some investigations related to the corrosion mechanism of Zr-based metallic glasses in solutions containing Cl-have been developed.However,few attentions have been paid to the situation in F--containing solution.This paper describes the corrosion behaviours of Zr52Al10Ni6Cu32 bulk metallic glass(BMG)in Na F and Na Cl aqueous solutions.The corrosion mechanism of Zr-based BMG in F–containing solution was proposed for the first time.It was found that in Na Cl solutions,Zr-based BMG samples underwent typical pitting corrosion.Selective dissolution of Zr,Al and enrichment of Cu were observed in corrosion pits.However,corrosion occurred in the form of general breakdown of passive film in Na F solutions.Such difference is interpreted in terms of the binding ability of anions to surrounding molecules,i.e.,Cl-with loose surrounding water passes through the passive film to cause pitting;F-with a tight surrounding molecules layer absorbs on passive film then coordinates with cations from matrix. | Zhangweijia Qiu Zhengkun Li Huameng Fu Hongwei Zhang Zhengwang Zhu Aimin Wang Hong Li Long Zhang Haifeng Zhang | 2020 | Journal of Materials Science & Technology2020，42，11： | 1 |

| 12 | Carbon-to-chlorophyll ratio and carbon content of phytoplankton community at the surface in coastal waters adjacent to the Zhujiang River Estuary during summer显示文摘Chlorophyll a(Chl a),particulate organic carbon(POC)and biogenic silica(BSi)were determined in coastal waters adjacent to the Zhujiang(Pearl)River Estuary(ZRE)during summer,in order to examine the C:Chl a ratio of phytoplankton and phytoplankton carbon in the plume-impacted coastal waters during summer,as well as to assess the relative contribution of diatoms to the phytoplankton biomass,by the regression between Chl a,POC and BSi.Our results showed that the C:Chl a ratio(g/g)of phytoplankton was high(up to 142),likely due to high light intensity and nutrient limitation.The river plume input stimulated phytoplankton growth,especially diatoms,resulting in higher relative contribution of phytoplankton carbon(55%)and diatoms(34%)to POC in the plume-impacted region than those(33%and 13%)in high salinity area,respectively.Phytoplankton carbon(up to 538μg/L)in the plume-impacted region was much higher than that(<166μg/L)in high salinity area.Our findings were helpful to improve the biogeochemical model in coastal waters adjacent to the ZRE. | Xiaoyong Yu Jie Xu Aimin Long Ruihuan Li Zhen Shi Qian P Li | 2020 | Acta Oceanologica Sinica2020，39，2： | 1 |

| 16 | Designing new work-hardenable ductile Ti-based multilayered bulk metallic glass composites with ex-situ and in-situ hybrid strategy显示文摘To overcome the trade-off between the devisable micro structure and the excellent tensile ductility of bulk metallic glass composites(BMGCs),a novel ex-situ and in-situ hybrid strategy is successfully proposed to design a series of the work-hardenable ductile Ti-based multilayered BMGCs(ML-BMGCs).The asprepared ML-BMGCs,consisting of α-phases,β-phases and amorphous phases,exhibit a controllable multilayered structure of the Ti layers and the amorphous layers with alternative distribution.The size and volume fraction of the crystalline phases are tuned by Nb microalloying.It is found that the ML-BMGCs possess a suitable size and volume fraction of the crystalline phases when Nb microalloying content are5%(at.) or 8%(at.),and they obtain an optimum combination of the specific strength of 243 MPa g kg-1 or 216 MPa g kg-1,and tensile plasticity of 4.33%±0.1 % or 5.10%±0.1%.The deformation mechanism of the as-prepared ML-BMGCs during tension is also revealed.The ex-situ Ti layers and in-situ dendrites together effectively serve as absorbers to suppress the propagation of shear bands and multiply shear bands.And the defo rmation of ex-situ α-Ti phases by dislocation slip and the transformation from in-situ metastable β-Ti phase to orthorhombic α-Ti during tension impart significant work-hardening capability to the ML-B MGCs.The present study provides a guidance of developing novel high-performance BMGCs with a controllable micro structure. | Shifeng Lin Zhengwang Zhu Shaofan Ge Long Zhang Dingming Liu Yanxin Zhuang Huameng Fu Hong Li Aimin Wang Haifeng Zhang | 2020 | Journal of Materials Science & Technology2020，47，15： | 1 |

| 18 | High-temperature Mechanical Properties and Dynamic Recrystallization Mechanism of in situ Silicide-reinforced MoNbTaTiVSi Refractory High-entropy Alloy Composite显示文摘The hypoeutectic composite material composed of BCC phase and in situ precipitated Ti_(5)Si_(3) was prepared by adding Si into MoNbTaTiV high-entropy alloy.The obvious oriented in situ Ti_(5)Si_(3) phase formed eutectic phase with BCC phase in the inter-dendritic area,which leads to excellent properties of the composite.The alloy exhibits ultra-high yield stress of 718 MPa at 1200℃ and obvious compression plasticity.After reaching the maximum strength,dynamic recovery(DRV)and dynamic recrystallization(DRX)caused soften phenomena.The DRX mechanism of the dual-phase eutectic structure is analyzed by electron backscatter diffraction.The DRX of the BCC phase conforms to the discontinuous DRX and continuous DRX mechanisms,while the Ti_(5)Si_(3) phase has a geometric DRX mechanism in addition to the above two mechanisms.The high performance of this composite has enough potential high-temperature applications such as nuclear and aero engine. | Shaofan Ge Shifeng Lin Huameng Fu Long Zhang Tieqiang Geng Zhengwang Zhu Zhengkun Li Hong Li Aimin Wang Hongwei Zhang Haifeng Zhang | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，10： | 1 |
