| 1 | Oxidative coupling of methane over (Na_2WO_4+Mn or Ce)/SiO_2 catalysts:In situ measurement of electrical conductivity显示文摘The effects of manganese oxide or ceria promoters on the performance of Na2WO4/SiO2 catalysts for oxidative coupling of methane (OCM) are reported. The OCM reaction was performed in a continuous-flow microreactor at 800 ℃, atmospheric pressure and under GHSV = 13200 ml gC-1at h-1. Catalysts were characterized by in situ conductivity measurement, FT-IR spectroscopy, XRD, SEM and temperature programmed reduction analysis. Manganese oxide promoted Na2WO4/SiO2 is considered as one of the active and selective catalysts for OCM reaction. Ceria with high oxygen storage capacity is selected as a proper oxygen activator, providing a higher concentration of the oxy-anion species which is suitable for OCM reaction and compared with manganese oxide. Electrical conductivity of the catalysts was measured in OCM reaction under oxidizing atmosphere, i.e. in the absence of methane. It was found that the trimetallic catalysts, i.e. the catalysts having sodium, tungsten and Mn or Ce species, exhibited similar crystalline structures and morphologies, which lead to suitable bulk properties for the formation of an active and selective catalyst. However, tungsten had significant effect on the texture and redox properties of the catalysts. It was also shown that the crystalline structure of the bimetallic (Na+Mn or Ce)/SiO2 samples was quite different. This reveals that the metal oxides have significant effect on the extent of crystallization, taking place in the course of interaction of sodium with silica support. Similar conductivities and catalytic performances of (Na2WO4+Mn or Ce)/SiO2 catalysts propose that the ability of Na2WO4/SiO2 for utilizing oxy-anions formed in presence of different metal oxides is limited. | Zeinab Gholipour Azim Malekzadeh Reza Hatami Yadollah Mortazavi Abasali Khodadadi | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 3 |

| 3 | Improvement in the protective performance and adhesion of polypyrrole coating on AZ31 Mg alloys显示文摘The electrochemical synthesis of polypyrrole(Ppy) coating on AZ31 magnesium alloy was successfully achieved in a solution containing sodium salicylate and monomer of pyrrole through cyclic voltammetry technique.The effect of potential range,passivation pretreatment and number of cycles of polymerization on the quality and protective performance of the coatings was evaluated using surface analysis and electrochemical techniques.Through taking the advantage of charge transfer resistance,current density,corrosion potential,optical microscopy images and SEM micrographs,the optimum condition of synthesis of a Ppy coating with the best adhesion and corrosion protection was determined.The optimal PPy coating synthesized over AZ31 increases the polarization resistance and decreases the corrosion current more than one order of magnitude and shift the corrosion potential about 200 mV toward nobler potentials.The SEM studies showed that Ppy coating have cauliflower morphology of Ppy grains with a diameter ranging from 20 nm to 60 nm. | Maryam Hatami Mohsen Saremi Reza Naderi | 2015 | Progress in Natural Science:Materials International2015，25，5： | 2 |

| 6 | Effect of fiber angle on LYP steel shear walls behavior显示文摘Steel shear wall(SSW) was properly determined using numerical and experimental approaches.The properties of SSW and LYP(low yield point) steel shear wall(LSSW) were measured.It is revealed that LSSW exhibits higher properties compared to SSW in both elastic and inelastic zones.It is also concluded that the addition of CFRP(carbon fiber reinforced polymers) enhances the seismic parameters of LSSW(stiffness,energy absorption,shear capacity,over strength values).Also,stress values applied to boundary frames are lower due to post buckling forces.The effect of fiber angle was also studied and presented as a mathematical equation. | Farzad Hatami Ali Ghamari Farshad Hatami | 2014 | Journal of Central South University2014，21，2： | 2 |
| 7 | Emotional evaluation of architectural interior forms based on personality differences using virtual reality显示文摘Recent studies have shown that architectural interior forms could impact the affective state of inhabitants.However,the direct relation of specific forms with specific affective states is difficult to determine.In addition,no systematic categorization of architectural forms and their relation to emotional states exists.The investigation of the impact of architectural features on inhabitants'emotions is further complicated by the use of two-dimensional images of forms in laboratory investigations,which cannot perceive real-world architecture.Furthermore,the interior form consists of a combination of different forms rather than only pure forms,which was considered in previous studies.This study aimed to rill these gaps by evaluating interior forms on the basis of clustering different images of built living rooms throughout history as well as their impact on emotions.This study used pleasure,arousal,and dominance ratings with an emphasis on individual differences in personality.Virtual sample rooms were created based on formal clusters of architectural forms.Results showed a relationship between forms and emotional states for different personality traits.This work provided a novel approach on the influence of architecture on emotion by considering systematic form categorization and combinations,personality differences,and a virtual reality setup. | Maryam Banaei Ali Ahmadi Klaus Gramann Javad Hatami | 2020 | Frontiers of Architectural Research2020，9，1： | 2 |

| 10 | Fischer-Tropsch synthesis over ruthenium-promoted Co/Al_2O_3 catalyst with different reduction procedures显示文摘The effect of reduction procedure on catalyst properties, activity and products selectivity of ruthenium-promoted Co/γ-Al2O3 catalyst in Fischer-Tropsch synthesis (FTS) was investigated. Catalyst samples were reduced with different reduction gas compositions and passivated before being characterized by TPR and XRD techniques. Different activity and product selectivity analyses were also performed. These results showed that the catalyst dispersion, particle size, and the degree of reduction changed with different reduction gas compositions, which were resulted from the water partial pressures in reduction process that give varying degrees of interaction with the support. It has been suggested that the FTS activity of cobalt catalyst was directly dependent on the catalyst reducibility. A reduction gas with a molar ratio of H2/He = 1 was used to prevent the formation of Co-support compound during catalyst reduction. | Ali Karimi Ali Nakhaei Pour Farshad Torabi Behnam Hatami Ahmad Tavasoli Mohammad Reza Alaei Mohammad Irani | 2010 | Journal of Natural Gas Chemistry2010，19，5： | 1 |
