| 1 | Improving methane storage on wet activated carbons at various amounts of water显示文摘Different mesoporous activated carbons were prepared by both chemical and physical activation processes and were examined for methane uptake in the presence of water.Methane isotherms were obtained at wet condition by wetting samples with water at mass ratio of water/carbon(R) close to 1.0.To compare,the amount of methane storage were also measured at dry situation.The maximum amount of methane stored was attained as 237 V/V at R=1.0 by hydrate formation at the methane critical pressure.In the next step,mass ratios of water/carbon were changed to investigate various amount of water for methane storage enhancement.Two other values of mass ratio of water/carbon(R=0.8 and 1.4) were selected and methane isotherms were obtained at the same conditions.Maximum values of 210 and 248 V/V were reached for methane storage,respectively.It was also observed that,in the pressure range lower than hydrate pressure,by increasing water ratio the hydrate formation pressure was decreased and methane uptake was much less than that of dry condition due to pore filling by water. | MOHAMMAD JABER DARABI MAHBOUB ALI AHMADPOUR HAMED RASHIDI | 2012 | 燃料化学学报2012,40,4: | 7 |
| 2 | Support effects on the chemical property and catalytic activity of Co-Mo HDS catalyst in sulfur recovery显示文摘Effects of carbon nanotubes (CNT) and alumina (γ-Al2O3) supports on the catalytic activities of hydrodesulfurization (HDS) process over CoMo catalyst have been studied. XRD results indicated that the main active phases in CNT and γ-Al2O3 supported Co-Mo catalysts are MoO2 and MoO3, respectively. The TPR results reveal that the reduction peak temperatures of the active species on CNT supported Co-Mo catalyst is lower than those on alumina supported Co-Mo catalyst, indicating that the CNT supports favor the reduction of active species. Catalytic evaluation results displayed that the sulfur content in the reaction products on the CNT supported Co-Mo catalyst is lower than that on the alumina supported Co-Mo catalyst if the HDS reaction was carried out at a temperature above 583 K. | Ali Nakhaei Pour Ali Morad Rashidi Kherolah Jafari Jozani Ali Mohajeri Payman Khorami | 2010 | Journal of Natural Gas Chemistry2010,19,1: | 7 |
| 3 | Parameter analysis of a photonic crystal fiber with raised-core index profile based on effective index method显示文摘Photonic crystal fibers (PCFs) with a stepped raised-core profile and one layer equally spaced holes in the cladding are analyzed. Using effective index method and considering a raised step refractive index difference between the index of the core and the effective index of the cladding, we improve the characteristic parameters such as numerical aperture and V-parameter, and reduce its bending loss to about one tenth of a conventional PCF. Implementing such a structure in PCFs may be one step forward to achieve low loss PCFs for communication applications. | Faramarz E.Seraji Mahnaz Rashidi Vajieh Khasheie | 2006 | Chinese Optics Letters2006,4,8: | 7 |
| 4 | Effect of Electroplating Parameters on Microstructure of Nanocrystalline Nickel Coatings显示文摘In order to achieve the optimum conditions for electroplating nanocrystalline nickel coating from Watts-type bath, the effect of some process parameters namely, bath temperature, current density, and saccharin addition on grain size and texture coefficient (TC= I(200)/I(111)) of the deposits were investigated by X-ray diffraction (XRD). The results showed that in a bath containing 5 g/L saccharin, by increasing the bath temperature from 45°C to 55°C, the grain size decreased, whereas further increase of bath temperature resulted in a contrary effect. By increasing the current density from 10 to 75 mA/cm2, both the grain size and TC decreased, while further increase in current density had no significant effect on the grain size. At a given current density, the grain size and TC decreased rapidly by increasing the saccharin content before leveling off at 3 g/L of saccharin. Finally, based on the grain refining the optimum conditions for producing nanocrystalline nickel coating from Watts-type bath have been proposed. | A.M. Rashidi A.

| 5 | SMFs-supported Pd nanocatalysts in selective acetylene hydrogenation:Pore structure-dependent deactivation mechanism显示文摘In the present study,CNFs,ZnO and Al2O3 were deposited on the SMFs panels to investigate the deactivation mechanism of Pd-based catalysts in selective acetylene hydrogenation reaction.The examined supports were characterized by SEM,NH3-TPD and N2adsorption-desorption isotherms to indicate their intrinsic characteristics.Furthermore,in order to understand the mechanism of deactivation,the resulted green oil was characterized using FTIR and SIM DIS.FTIR results confirmed the presence of more unsaturated constituents and then,more branched hydrocarbons formed upon the reaction over alumina-supported catalyst in comparison with the ones supported on CNFs and ZnO,which in turn,could block the pores mouths.Besides the limited hydrogen transfer,N2 adsorption-desorption isotherms results supported that the lowest pore diameters of Al2O3/SMFs close to the surface led to fast deactivation,compared with the other catalysts,especially at higher temperatures. | Elaheh Esmaeili Ali Morad Rashidi Yadollah Mortazavi Abbas Ali Khodadadi Mehdi Rashidzadeh | 2013 | Journal of Energy Chemistry2013,22,5: | 5 |
| 6 | Transcranial direct current stimulation for auditory verbal hallucinations:a systematic review of clinical trials显示文摘Transcranial direct current stimulation(tDCS)has been reportedly beneficial for different neurodegenerative disorders.tDCS has been reported as a potential adjunctive or alternative treatment for auditory verbal hallucination(AVH).This study aims to review the effects of tDCS on AVH in patients with schizophrenia through combining the evidence from randomized clinical trials(RCTs).The databases of PsycINFO(2000–2019),PubMed(2000–2019),EMBASE(2000–2019),CINAHL(2000–2019),Web of Science(2000–2019),and Scopus(2000–2019)were systematically searched.The clinical trials with RCT design were selected for final analysis.A total of nine RCTs were eligible and included in the review.Nine RCTs were included in the final analysis.Among them,six RCTs reported a significant reduction of AVH after repeated sessions of tDCS,whereas three RCTs did not show any advantage of active tDCS over sham tDCS.The current studies showed an overall decrease of approximately 28%of AVH after active tDCS and 10%after sham tDCS.The tDCS protocols targeting the sensorimotor frontal-parietal network showed greater treatment effects compared with the protocols targeting other regions.In this regard,cathodal tDCS over the left temporoparietal area showed inhibitory effects on AVHs.The most effective tDCS protocol on AVHs was twice-daily sessions(2 mA,20-minute duration)over 5 consecutive days(10 sessions)with the anode over the left dorsolateral prefrontal cortex and the cathode over the left temporal area.Some patient-specific and diseasespecific factors such as young age,nonsmoking status,and higher frequencies of AVHs seemed to be the predictors of treatment response.Taken together,the results of tDCS as an alternative treatment option for AVH show controversy among current literatures,since not all studies were positive.However,the studies targeting the same site of the brain showed that the tDCS could be a promising treatment option to reduce AVH.Further RCTs,with larger sample sizes,should be conducted to reach a conclusion on the efficacy of tDCS for AVH and to develop an effective therapeutic protocol for clinical setting. | Samaneh Rashidi Myles Jones Eric Murillo-Rodriguez Sergio Machado Youguo Hao Ali Yadollahpour | 2021 | Neural Regeneration Research2021,16,4: | 4 |
| 7 | Production of single-walled carbon nanotubes from methane over Co-Mo/MgO nanocatalyst:A comparative study of fixed and fluidized bed reactors显示文摘In this study,the performances of fixed and fluidized bed reactors in the production of single-walled carbon nanotubes(SWNTs)have been investigated.In both reactors,single-walled carbon nanotubes were grown by catalytic chemical vapor decomposition(CCVD)of methane over Co-Mo/MgO nanocatalyst under two different operating conditions.The synthesized samples were characterized by TEM,TGA and Raman spectroscopy.It is found that the performance of a fluidized bed in the synthesis of carbon nanotubes is much better than that of a fixed bed.The quality of carbon nanotubes obtained from the fluidized bed was significantly higher than that from the fixed bed and the former one with the ID/IG ratio of 0.11 while the latter one with the ID/IG ratio of 0.71.Also,the yield of SWNTs in the fluidized bed was 92 wt%,while it was 78 wt%in the fixed bed.These advantages of fluidized bed reactors for the synthesis of carbon nanotubes can be attributed to more available space for the growth of carbon nanotubes and more uniform temperature and concentration profiles. | Alimorad Rashidi Roghayeh Lotfi Ehsaneh Fakhrmosavi Masoud Zare | 2011 | Journal of Natural Gas Chemistry2011,20,4: | 3 |

| 11 | Immunogenicity of recombinant hepatitis B virus vaccine in patients with and without chronic hepatitis C virus infection:A case-control study显示文摘AIM: To compare the response of standard hepatitis B virus (HBV) vaccination between patients with chronic hepatitis C virus (HCV) infection and healthy individuals. METHODS: This is a prospective case-control study. A total of 38 patients with chronic HCV infection and 40 healthy controls were included. Vaccination was performed by injection of 20 μg recombinant HBsAg into the deltoid muscle at mo 0, 1 and 6. Anti-HBs concentration was determined 3 mo after the last dose and compared between the two groups. The response pattern was characterized as (1) high-response when the anti-HBs antibody titer was > 100 IU/L, (2) low-response when the titer was 10-100 IU/L and (3) no-response when the titer was < 10 IU/L. RESULTS: In the patient group, there were 10/38 (26.3%) non-responders, 8/38 (21.1%) low-responders and 20/38 (52.6%) high-responders. The corresponding values in the control group were 2/40 (5.0%), 7/40 (17.5%) and 31/40 (77.5%), respectively. The response pattern was statistically different between the two groups. In multivariate analysis, smoking was a significant confounder, while HCV infection lost its significant correlation with lower antibody response. CONCLUSION: Patients with chronic HCV infection tend to respond weakly to HBV vaccination compared to healthy individuals, though this correlation is not independent according to multivariate analysis. | Naser Ebrahimi Daryani Mohsen Nassiri-Toosi Armin Rashidi Iman Khodarahmi | 2007 | World Journal of Gastroenterology2007,13,2: | 2 |
| 12 | Prospective evaluation of the cause of acute pancreatitis,with special attention to medicines显示文摘AIM: To investigate the cause of acute pancreatitis(AP) by conducting a thorough investigation of drugs and their possible etiological role.METHODS: We investigated the cause of AP in a large retrospective cohort of 613 adult patients admitted with AP at the Akershus University Hospital, Norway, from 2000 until 2009, who were evaluated with standard ward investigations. This group was compared with a prospectively evaluated group(n = 57) admitted from January 2010 until September 2010 who investigated more extensively using medical history and radiological assessment.RESULTS: The groups were comparable with regards to gender, age, comorbidity and severity. The most common etiology was bile stones and alcohol, occurring in 60% in both groups. The prospective group was examined more thoroughly with regards to the use of alcohol and medicines. An increased number of radiological investigations during hospital stay and at follow-up were also performed. A more extensive use of radiological evaluation did not increase the detection frequency of bile stones. In the prospective group, more than half of the patients had two or more possible causes of pancreatitis, being mostly a combination of bile stones and drugs. No possible cause was found in only 3.5% of these patients, compared with 29.7% in the retrospective group.CONCLUSION: A detailed medical history and extensive radiological evaluation may determine a possible etiology in almost all cases of AP. Many patients have several possible risk factors, and uncertainty remains in establishing the definitive etiology. | Mitra Rashidi Ola Røkke | 2016 | World Journal of Gastroenterology2016,22,6: | 2 |
| 13 | 纳米TiO_2/炭黑改性PET织物及其导电与光活性的表征(英文)显示文摘对聚对苯二甲酸乙二醇酯(PET)织物进行碱性水解预处理。通过浸渍法以十二烷基硫酸钠作为分散剂在原始的和经预处理的PET中加入纳米炭黑(CB1515和CB156),纳米二氧化钛(NTO)-NCBs(CB1515或CB156)混合物。以柠檬酸(CA)和次磷酸钠(SHP)分别为交联剂和催化剂,分别在预处理前后的PETs中加入NTO+CB1515和NTO+CB156作对比研究。结果表明,CB156比CB1515更能有效地降低样品的电阻率。加入NTO后,由原始PET所制样品比预处理PET所制样品具有更低的电阻率。然而,这与不加NTO所制样品结果相反。通过增加添加量和改善NCBs和NTO在织物中的分散均匀性,采用CA和SHP可明显降低样品的电阻率。发现NCBs与NTO的协同效应可提高预处理织物的紫外吸收。由原始PET中加入NCB和NTO所制样品比预处理的PET对亚甲基蓝降解具有更高活性。通过添加NTO或CA-SHP可提高活性,前者比后者更有效。 | A Ebrahimbeiki Chimeh M Montazer A Rashidi | 2013 | 新型炭材料2013,28,4: | 2 |
| 14 | Hydrocarbon Vertical Continuity Evaluation in the Cretaceous Reservoirs of Azadegan Oilfield, Southwest of Iran: Implications for Reservoir Geochemistry显示文摘A collection of data obtained from analytical methods in geochemistry along with the reservoir engineering and geologic data were used to investigate the reservoir continuity in the Cretaceous Fahliyan, Gadavan, Kazhdumi and Sarvak reservoirs of the super-giant Azadegan oilfield, SW Iran. The geochemical data indicate that the oil samples, with medium to high level of thermal maturity, have been generated from the anoxic marine marl/carbonate source rock(s). The Sargelu(Jurassic) and Garau(Cretaceous) formations are introduced as the main source rocks for the studied oils. The dendrogram obtained from the cluster analysis of high-resolution gas chromatography data introduces two main oil groups including Fahliyan reservoir, and Kazhdumi along with Sarvak/Gadvan reservoirs. This is confirmed by C7 Halpern star diagram, indicating that, the light oil fraction from Fahliyan reservoir is distinct from the others. Also, different pressure gradient of the Fahliyan Formation(over-pressured) relative to other reservoirs(normally-pressured) show the presence of compartments. The relation between toluene/n-heptane and n-heptane/methylcyclohexane represents the compartmentalization due to maturation/evaporative fractionation for Fahliyan and water washing for other studied reservoirs. Also, the impermeable upper part of the Fahliyan Formation and thin interbedded shaly layers in the Kazhdumi, Sarvak and Gadvan formations have controlled reservoir compartmentalization. | Bahram ALIZADEH Mehrab RASHIDI Alireza ZARASVANDI Seyed Rasoul SEYEDALI Mohammad Hasan ALIEE | 2020 | Acta Geologica Sinica(English Edition)2020,94,3: | 2 |
| 15 | 基于图像和飞行时间的基础设施三维重建技术比较显示文摘竣工空间数据在众多与建筑相关的应用方面颇为实用,例如质量控制和进度监控。这些数据可以通过使用多种基于图像和基于飞行时间的(例如激光扫描)传感器法来收集。每种应用都对数据的精度和质量水平有特定要求,但几乎没有什么信息可以帮助工程师选择最具成本效益的数据收集方法。本文对摄影测量法、摄像测量法和基于飞行时间法在精度、质量、时间效率和成本方面进行了分析和定量比较。为此,对具有代表性的基于图像的三维重建软件和商用硬件(两台相机和一台飞行时间激光扫描仪)进行了评价。使用不同的设置收集了典型基础设施(2座桥梁和1栋楼)的空间数据。实验参数包括成像传感器的相机类型、分辨率和拍摄距离。通过将这些数据与全站仪收集的地面实况进行比较,发现摄像/摄影测量可以产生中等精度和质量的结果,但成本比激光扫描低得多。所获得的信息有助于工程师做出具有成本效益的决策,并帮助研究人员更好地了解这些设置对传感器技术的性能影响。 | 蔡建国(译) Fei Dai Abbas Rashidi loannis Brilakis | 2021 | 四川建材2021,47,2: | 2 |
