| 1 | Ultrasound-assistant preparation of Cu-SAPO-34 nanocatalyst for selective catalytic reduction of NO by NH_3显示文摘The influence of the various preparation methods of Cu-SAPO-34 nanocatalysts on the selective catalytic reduction of NO with NH3 under excess oxygen was studied. Cu-SAPO-34 nanocatalysts were prepared by using four techniques: conventional impregnation(IM),ultrasound-enhanced impregnation(UIM), conventional deposition precipitation(DP) using Na OH and homogeneous deposition precipitation(HDP) using urea. These catalysts were characterized in detail by various techniques such as N2-sorption, XRD, TEM, H2-TPR,NH3-TPD and XPS to understand the catalyst structure, the nature and the dispersed state of the copper species, and the acid sites for NH3 adsorption. All of the nanocatalysts showed high activities for NO removal. However, the activities were different and followed the sequence of Cu-SAPO-34(UIM) > Cu-SAPO-34(HDP) > Cu-SAPO-34(IM) > Cu-SAPO-34(DP).Based on the obtained results, it was concluded that the NO conversion on Cu-SAPO-34 nanocatalysts was mainly related to the high reducibility of the isolated Cu2+ions and Cu O species, the number of the acid sites and the dispersion of Cu O species on SAPO-34. | Parvaneh Nakhostin Panahi Ali Niaei Darush Salari Seyed Mahdi Mousavi Gérard Delahay | 2015 | Journal of Environmental Sciences2015，27，9： | 7 |

| 12 | 纳米分子筛催化剂(Cu,Mn,Fe,Co等)选择性催化NH_3还原NO:Taguchi方法的过程优化(英文)显示文摘A series of different transition metals(V,Co,Cr,Mn,Fe,Ni,Cu and Zn) promoted H-ZSM-5 catalysts were prepared by impregnation method and characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and transmission electron microscopy(TEM).The catalytic activity of these catalysts was evaluated for the selective catalytic reduction(SCR) of NO with NH_3 as reductant in the presence of oxygen.The results revealed that the catalytic activity of Cu-ZSM-5 nanocatalyst for NO conversion to N_2 was 80%at 300 ℃,which was the best among various promoted metals.Design of experiments(DOEs) with Taguchi method was employed to optimize NH_3-SCR process parameters such as NH_3/NO ratio,O_2 concentration,and gas hourly space velocity(GHSV) over Cu-ZSM-5 nanocatalyst at 250 and 300 ℃.Results showed that the most important parameter in NH_3-SCR of NO is O_2 concentration;followed by NH_3/NO ratio and GHSV has little importance.The NO conversion to N_2 of 63.1%and 94.86%was observed at 250℃ and 300℃,respectively under the obtained optimum conditions. | Parvaneh Nakhostin Panahi Darush Salari Aligholi Niaei Seyed Mahdi Mousavi | 2015 | Chinese Journal of Chemical Engineering2015，23，10： | 1 |

| 14 | Validation of the functional rating index for the assessment of athletes with neck pain显示文摘AIM: To validate the culturally-adapted Persian Functional Rating Index(PFRI) for assessing neck pain(NP) in athletes. METHODS: In this cross-sectional study, 100 athletes with NP and 50 healthy athletes participated and responded to the PFRI. Fifty athletes with NP completed the PFRI for at least 7 d later to establish test-retest reliability. RESULTS: The athletes with NP responded to all items, indicating excellent clinical utility. No floor and ceiling effects were found, indicating content validity and responsiveness. The PFRI revealed capability to discriminate between the athletes with NP and healthy athletes. The PFRI demonstrated strong correlation with the Numerical Rating Scale(Spearman's rho = 0.94), and the Persian Neck Disability Index(Pearson r = 0.995), supporting criterion and construct validity. Internal consistency reliability was high(Cronbach's α coefficient: 0.97). The test-retest reliability was excellent(ICCagreement = 0.96). The absolute reliability values of standard error of measurement and smallest detectable change were 3.2 and 8.84, respectively. An exploratory factor analysis yielded one factor explaining 78.03% of the total variance. CONCLUSION: The PFRI is a valid and reliable measure of functional status in athletes with NP. | Soofia Naghdi Noureddin Nakhostin Ansari Somaye Shams Salehi Ronald J Feise Ebrahim Entezary | 2016 | World Journal of Orthopedics2016，7，8： | 0 |
