| 1 | Effect of strontium substitution on the activity of La_(2-x)Sr_xNiO_4(x=0.0-1.2)in NO decomposition显示文摘The aim of this work is to study the effect of Sr substitution on the redox properties and catalytic ac- tivity of La2-xSrxNiO4(x=0.0-1.2)for NO decomposition.Results suggest that the x=0.6 sample shows the highest activity.The characterization(TPD,TPR,etc.)of samples indicates that the x=0.6 sample possesses suitable abilities in both oxidation and reduction,which facilitates the proceeding of oxygen desorption and NO adsorption.At temperature below 700℃,the oxygen desorption is difficult, and is the rate-determining step of NO decomposition.With the increase of reaction temperature(T> 700℃),the oxygen desorption is favorable and,the active adsorption of NO on the active site(NO+Vo+ Ni2+→NO^--Ni3+)turns out to be the rate-determining step.The existence of oxygen vacancy is the prerequisite condition for NO decomposition,but its quantity does not relate much to the activity. | ZHU JunJiang 1 ,YANG XiangGuang 2 ,XU XueLian 3 &WEI KeMei 1 1 National Research Center of Chemical Fertilizer Catalysts,Fuzhou University,Fuzhou 350002,China 2 Changchun Institute of Applied Chemistry,Chinese Academy of Sciences,Changchun 130022,China 3College of Chemistry&Chemical Engineering,Fuzhou University,Fuzhou 350002,China | 2007 | Science China Chemistry2007，50，1： | 4 |

| 9 | Plasma Surface Cu Alloyed Layer as a Lubricant on Stainless Steel Sheet:Wear Characteristics and On-job Performance in Incremental Forming显示文摘To solve the problems of poor forming and easy adhesion of the stainless steel,Cu alloyed layer on the stainless steels was prepared by the double glow plasma surface alloying technique.The experimentalresults indicated that the supersaturated copper dispersedly precipitated in grain interior and crystalboundaries and formed the vermicular structure.The tribologicaltests indicated that the friction coefficient of the Cu alloyed layer was lower than that of the stainless steels.The wear rate of stainless steelin the presence of Cu alloyed layer was approximately 2-fold lower than that in the absence of the alloyed layer.The results of the incrementalforming indicated that the ploughing phenomenon was not observed on the stainless steelin the presence of Cu alloyed layer during the incrementalforming,while the stainless steelpresented the deep ploughing.Therefore,Cu alloyed layer on stainless steelexhibited excellent self-lubrication and forming properties. | 吴红艳 WEI Hongyu Ghulam Hussain TAO Kemei Asif Iqbal 饶伟峰 | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，2： | 1 |

| 16 | Characteristics and removal mechanism of the precursors of N-chloro-2,2-dichloroacetamide in a drinking water treatment process at Taihu Lake显示文摘N-chloro-2,2-dichloroacetamide(N-Cl-DCAM)is an emerging nitrogenous disinfection by-product(N-DBP)which can occur in drinking water.In this study,an analytical method based on liquid chromatography with tandem mass spectrometry(LC-MS/MS)was developed to validate the concentration of N-Cl-DCAM,which was found to be 1.5µg/L in the effluent of a waterworks receiving raw water from Taihu Lake,China.The changes of N-Cl-DCAM formation potential(N-Cl-DCAMFP)in the drinking water treatment process and the removal efficiency of its precursors in each unit were evaluated.Non-polar organics accounted for the majority of N-Cl-DCAM precursors,accounting for 70%of the N-Cl-DCAM FP.The effect of conventional water treatment processes on the removal of N-Cl-DCAM precursors was found to be unsatisfactory due to their poor performance in the removal of low molecular weight(MW)or non-polar organics.In the ozonation integrated with biological activated carbon(O_(3)-BAC)process,the ozonation had little influence on the decrease of N-Cl-DCAM FP.The removal efficiency of precursors by a new BAC filter,in which the granular activated carbon(GAC)had only been used for four months was higher than that achieved by an old BAC filter in which the GAC had been used for two years.The different removal efficiencies of precursors were mainly due to the different adsorption capacities of GAC for individual precursors.Low MW or non-polar organics were predominantly removed by GAC,rather than biodegradation by microorganisms attached to GAC particles. | Mengqing Ge Tao Lin Kemei Zhou Hong Chen Hang Xu Hui Tao Wei Chen | 2021 | Frontiers of Environmental Science & Engineering2021，15，5： | 1 |
