| 2 | 3D-printed MoS_(2)/Ni electrodes with excellent electro-catalytic performance and long-term stability for dechlorination of florfenicol显示文摘Here,we report the production of 3D-printed MoS_(2)/Ni electrodes(3D-MoS_(2)/Ni)with longterm stability and excellent performance by the selective laser melting(SLM)technique.As a cathode,the obtained 3D-MoS_(2)/Ni could maintain a degradation rate above 94.0%for forfenicol(FLO)when repeatedly used 50 times in water.We also found that the removal rate of FLO by 3D-MoS_(2)/Ni was about 12 times higher than that of 3D-printed pure Ni(3D-Ni),attributed to the improved accessibility of H^(*).In addition,the electrochemical characterization results showed that the electrochemically active surface area of the 3D-MoS_(2)/Ni electrode is about 3-fold higher than that of the 3D-Ni electrode while the electrical resistance is 4 times lower.Based on tert-butanol suppression,electron paramagnetic resonance and triple quadrupole mass spectrometer experiments,a“dual path”mechanism and possible degradation pathway for the dechlorination of FLO by 3D-MoS_(2)/Ni were proposed.Furthermore,we also investigated the impacts of the cathode potential and the initial pH of the solution on the degradation of FLO.Overall,this study reveals that the SLM 3D printing technique is a promising approach for the rapid fabrication of high-stability metal electrodes,which could have broad application in the control of water contaminants in the environmental field. | Jianhui Xu Pengxu Wang Shenggui Chen Lei Li Dan Li Yunfei Zhang Qi Wu Jinhong Fan LumingMa | 2024 | Journal of Environmental Sciences2024，，3： | 1 |
| 3 | Towards Comprehensive Provable Data Possession in Cloud Computing显示文摘To check the remote data integrity in cloud computing,we have proposed an efficient and full data dynamic provable data possession(PDP) scheme that uses a SN(serial number)-BN(block number) table to support data block update.In this article,we first analyze and test its performance in detail.The result shows that our scheme is efficient with low computation,storage,and communication costs.Then,we discuss how to extend the dynamic scheme to support other features,including public auditability,privacy preservation,fairness,and multiple-replica checking.After being extended,a comprehensive PDP scheme that has high efficiency and satisfies all main requirements is provided. | LI Chaoling CHEN Yue TAN Pengxu YANG Gang | 2013 | Wuhan University Journal of Natural Sciences2013，18，3： | 1 |
| 4 | Anti-tarnish property of sterling silver alloy with yttrium addition显示文摘It has been demonstrated that sterling silver alloy is a widely used material in the jewelry industry. The anti-tarnish property is one of the most important properties of this material. In this work, the effect of yttrium on the corrosion resistance, and tarnish resistance properties of sterling silver alloy were investigated with the use of CIE-LAB uniform color scale, which gained acceptance as an effective way to assess color. To better understand the mechanism of the effect, the distribution of yttrium in the alloy was analyzed by mainly segregating in gaps among dendrite crystals and grain boundary. An increase in yttrium content in sterling silver alloy resulted in a decrease in the amount of eutectic structure. The tarnish and corrosion resistance of sterling silver were improved with yttrium content increase. However, too high yttrium content will lead to poor anti-tarnish properties. | XIANG Xiongzhi BAI Xiaojun CHEN Pengxu | 2012 | Rare Metals2012，31，5： | 1 |
| 5 | South-hemispheric marine aerosol Hg and S isotope compositions reveal different oxidation pathways显示文摘Particle-bound mercury(PBM)records the oxidation of elemental mercury,of which the main oxidation pathways(Br∙/Cl∙/OH∙/O3)remain unclear,especially in the Southern Hemisphere.Here,we present latitudinal covariations of Hg and Sisotopic anomalies in cross-hemispheric marine aerosols that evidence an equator-to-poleward transition of Hg oxidants from OH∙/O3 in tropics to Br∙/Cl∙in polar regions highlighting thus the presence of distinct oxidation processes producing PBM.The correlations between Hg,S and O-isotopic compositions measured in PBM,sulfates and nitrates respectively within the aerosols highlight the implication of common oxidants in their formations at different latitudes.Our results open a new window to better quantify the present-day atmospheric Hg,S and N budgets and to evaluate the influences of aerosols on climate and ecosystems once the isotopic fractionations associated with each process have been determined. | David AuYang Jiubin Chen Wang Zheng Yanxu Zhang Guitao Shi Jeroen ESonke Pierre Cartigny Hongming Cai Wei Yuan Liangzhi Liu Pengxue Gai Congqiang Liu | 2022 | National Science Open2022，1，2： | 1 |
| 6 | Development of MoS_(2)-stainless steel catalyst by 3D printing for efficient destruction of organics via peroxymonosulfate activation显示文摘Herein,a novel MoS_(2)-stainless steel composite material was first synthetized via a 3D printing method(3DP MoS_(2)-SS)for peroxymonosulfate(PMS)activation and organics degradation.Compared with MoS_(2)-SS powder/PMS system(0.37 g/(m^(2)/min)),4.3-fold higher k_(FLO)/S_(BET)value was obtained in 3DP MoS_(2)-SS/PMS system(1.60 g/(m^(2)/min),resulting from the superior utilization of active sites.We observed that 3DP MoS_(2)-SS significantly outperformed the 3DP SS due to the enhanced electron transfer rate and increased active sites.Moreover,Mo^(4+)facilitated the Fe^(2+)/Fe^(3+)cycle,resulting in the rapid degradation of florfenicol(FLO).Quenching experiments and electron paramagnetic resonance spectra indicated that·OH,SO_(4)·^(-),O_(2)·^(-)and^(1)O_(2)were involved in the degradation of FLO.The effect of influencing factors on the degradation of FLO were evaluated,and the optimized degradation efficiency of 98.69%was achieved at 1 mM PMS and pH of 3.0.Six degradation products were detected by UPLC/MS analyses and several possible degradation pathways were proposed to be the cleavage of C-N bonds,dechlorination,hydrolysis,defluorination and hydroxylation.In addition,3DP MoS_(2)-SS/PMS system also demonstrated superior degradation performance for 2-chlorophenol,acetaminophen,ibuprofen and carbamazepine.This study provided deep insights into the MoS_(2)-SS catalyst prepared by 3DP technology for PMS activation and FLO-polluted water treatment. | Yufeng Liu Jianhui Xu Xin Fu Pengxu Wang Dan Li Yunfei Zhang Shenggui Chen Chunhui Zhang Peng Liu | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
