| 1 | 超级电容器用生物质基多孔炭的研究进展显示文摘在最近的几十年中,超级电容器(SC)已在电化学能量存储设备中获得了更为重要的地位。SC为使用寿命长的能量存储设备提供了可观的功率密度和令人满意的能量密度,适用于多种应用。因此,这些装置的进一步发展依赖于提供合适,低成本,环境友好和丰富的材料作为SC的电极活性材料。在用于SC的电极材料中,活性炭表现出优异的性能。它们具有优异的电化学效率,高比表面积,高吸附性,可调节的表面化学性质,快速的离子/电子传输,低成本和丰富的特性,使其成为SC电极的最佳材料。如果从生物质前驱体制备活性炭,则可以协同增强这些优势。由于生物质为可再生来源,低成本,便捷的加工过程以及对环境的友好性,研究者们将注意力集中在生物质上。在本文中,试图全面了解作为电化学储能装置的SC的基本原理。然后,对各种来源的生物质进行分类和分析。最后,讨论了这些生物质前驱体作为SCs电极材料的应用和活化技术。 | Majid Shaker Ali Asghar Sadeghi Ghazvini 曹蔚琦 Reza Riahifar 葛奇 | 2021 | 新型炭材料2021，36，3： | 9 |
| 2 | Diagnostic accuracy of fluorine-18-fluorodeoxyglucose positron emission tomography in gallbladder cancer: A meta-analysis显示文摘AIM: To meta-analyze published data about the diagnostic accuracy of fluorine-18-fluorodeoxyglucose(18F-FDG) positron emission tomography(PET) and PET/computed tomography(PET/CT) in the evaluation of primary tumor in patients with gallbladder cancer(GBCa).METHODS: A comprehensive literature search of studies published through 30 th June 2014 regarding the role of 18F-FDG PET and PET/CT in the evaluation of primary gallbladder cancer(GBCa) was performed. All retrieved studies were reviewed. Pooled sensitivity and specificity of 18F-FDG PET or PET/CT in the evaluation of primary GBCa were calculated. The area under the summary receiving operator characteristics curve(AUC) was calculated to measure the accuracy of these methods. Sub-analyses considering the device used(PET vs PET/CT) were carried out.RESULTS: Twenty-one studies comprising 495 patients who underwent 18F-FDG PET or PET/CT for suspicious GBCa were selected for the systematic review. The meta-analysis of 13 selected studies provided the following results: sensitivity 87%(95%CI: 82%-92%),specificity 78%(95%CI: 68%-86%). The AUC was 0.88. Improvement of sensitivity and specificity was observed when PET/CT was used.CONCLUSION: 18F-FDG-PET and PET/CT demonstrated to be useful diagnostic imaging methods in the assessment of primary tumor in GBCa patients,nevertheless possible sources of false-negative and false-positive results should be kept in mind. PET/CT seems to have a better diagnostic accuracy than PET alone in this setting. | Salvatore Annunziata Daniele Antonio Pizzuto Carmelo Caldarella Federica Galiandro Ramin Sadeghi Giorgio Treglia | 2015 | World Journal of Gastroenterology2015，21，40： | 8 |
| 3 | LaZn_xFe_(1-x)O_3钙钛矿型纳米催化剂的制备、表征及其甲苯燃烧性能(英文)显示文摘Nanostructured LaFeO3 and substituted LaZnxFe1-xO3(x = 0.01,0.05,0.1,0.2,and 0.3) perovskites were synthesized by the sol-gel auto-combustion method and used in the catalytic combustion of toluene.Their structures and surface properties were investigated by X-ray diffraction,Fourier transmission infrared spectroscopy,BET surface area,and scanning electron microscopy.Characterization data revealed that the total insertion of zinc into LaFeO3 takes place when x ≤ 0.1.However,ZnO segregation occurs to some extent,especially at x > 0.1.The performance of these perovskites was evaluated by toluene combustion.The catalytic activity of the catalysts increased substantially with an increase in zinc substitution.These results can be attributed to the cooperative effect between LaZnxFe1-xO3 and the zinc oxide phases.The relative concentration of these phases determines their oxygen activation ability and reactivity. | Seyed Ali HOSSEINI Mohammad Taghi SADEGHI Abdolali ALEMI Aligholi NIAEI Dariush SALARI Leila KAFI-AHMADI | 2010 | 催化学报2010，31，7： | 7 |

| 5 | 微空心阴极放电机理及其在电热式推力器中的应用显示文摘近年来,微空心阴极放电(MHCD)技术的发展为研制适用于小卫星的先进新型微推力器提供了可能。MHCD是微放电领域中一种新颖的非平衡高气压辉光放电,其优点是可以在高气压下稳定放电,并且只需要非常低的电压(几百伏特)或者输入功率(百毫瓦数量级)。本文针对MHCD,实验研究了微放电的电流-电压特性,并利用光学发射光谱的方法测量了微等离子体中电子数密度和中性气体温度。结果表明,在稳定的辉光放电下,MHCD孔内的电子数密度和中性气体温度随着压强和放电电流的增加而增大,电子数密度可达1014cm-3,中性气体温度可达1000K。由此可以推断,微空心阴极放电较小的尺寸结构与强烈并可控的气体加热相结合,完全可以开发应用在新型的电热式等离子体推进上,研制成微空心阴极放电等离子体推力器。由于在微放电等离子体中加热了工质气体,因此其性能可大大高于冷气推进。 | 夏广庆 毛根旺 Nader Sadeghi | 2008 | 宇航学报2008，29，5： | 6 |
| 6 | Field investigation on effects of railway track geometric parameters on rail wear显示文摘Rail wear has dramatic impact on track performance, ride quality and maintenance costs. The amount of rail wear is influenced by various elements among which geometric parameters play an important role. The amount of wear in Iran’s railway lines and its imposed maintenance costs oblige us to make modifications on the various geometrical parameters. In order to ensure the effectiveness of these changes, it is necessary to investigate these parameters and their effects on the wear. This research is aimed at studying the effects of different track geometrical parameters on the vertical and lateral wear by conducting a three phase field investigation. The first phase was carried out at the switches of a station, the second phase at a straight line, and the third at a curved line out of the station. The results obtained are analyzed and the role of each track geometrical parameter in the rail wear is discussed. Recommendations for prevention or reduction of rail wear are presented. | SADEGHI J.

| 8 | Overlapping gastroesophageal reflux disease and irritable bowel syndrome:Increased dysfunctional symptoms显示文摘AIM:To investigate the association of gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) in Iranian patients and examine the prevalence of functional symptoms of the gastrointestinal tract in patients presenting with either IBS, GERD or both.METHODS: Six thousand four hundred and seventy six patients presented to the Gastro-intestinal (GI) clinic with symptoms of functional dysfunction of GI tract, 1419 patients (62.0% women, 38.0% men; mean age: 37.4±11.5 years) met Rome or Rome criteria(depending on the year of diagnosis)for IBS.2658 patients were diagnosed with GERD based on clinical presentation and endoscopic findings.We assessed other functional symptoms(epigastric pain,nausea,vomiting,belching,constipation and diarrhea)in patients suffering from GERD,IBS or both.RESULTS: Among IBS subjects, 63.6% (69.0% women, 31.0% men; mean age: 36.4±10.3 years) also hadGERD, whereas 34.7% of the non-IBS patients had GERD [odds ratio (OR) =3.2, 95% confidence interval (CI): 2.9-3.7, P<0.0001]. Among patients with GERD, 33.9% of subjects met Rome criteria compared to 13.5% of non-GERD patients (OR=3.6, 95% CI: 3.1-4.3, P<0.0001). Prevalence of all functional symptoms was higher in overlapping GERD and IBS subjects, when compared with their prevalence in the IBS subjects without GERD or GERD only subjects (P<0.05).CONCLUSION: This finding shows that in overlapping GERD and IBS, other functional abnormalities of the GI tract are also highly prevalent, suggesting a common underlying dysfunction. | Shadi Sadeghi Yarandi Siavosh Nasseri-Moghaddam Pardis Mostajabi Reza Malekzadeh | 2010 | World Journal of Gastroenterology2010，16，10： | 5 |
| 9 | A new impedance and robust adaptive inverse control approach for a teleoperation system with varying time delay显示文摘This paper presents a new robust adaptive inverse control approach for a force-reflecting teleoperation system with varying time delay. First,an impedance control is designed for the master robot. Second,an adaptive inverse control is proposed for the slave robot. Finally,the slave side controller is modified such that the robust stability and performance are achieved. In addition,robust stability analysis has been performed and optimal behavior is ensured by using standard characteristic polynomials. It is shown that despite of presence of randomly-varying time delay,the proposed control algorithm compensates the position drifts efficiently. Demonstrable simulation studies confirm the effectiveness of the proposed control system and its advantages over the existing sliding mode control strategies. | Mokhtar SHA SADEGHI Hamid Reza MOMENI | 2009 | Science China(Technological Sciences)2009，52，9： | 5 |
| 10 | Anisotropy of mechanical properties and crystallographic texture in hot rolled AZ31+XSr sheets显示文摘The influences of Sr on the microstructure,texture and mechanical properties including flow and anisotropy behavior of AZ31 alloys are investigated.Slabs containing no,0.4 and 0.8 wt%of strontium were cast and subjected to hot rolling.Results indicate that Sr reduces the basal texture intensity(23%in the AZ31+0.8Sr alloy)and homogenizes the distribution of strain in uniaxial tension.Furthermore,Sr increases both the strength coefficient and the strain hardening exponent in all directions.In the transverse direction,enhancements are more significant.Moreover,Sr enhances the combination of tensile strength and total elongation;i.e.,toughness,whether tests are performed parallel to the rolling,diagonal or transverse directions,to significant extents. | Alireza Sadeghi Hossein Mortezapour Javad Samei Mihriban Pekguleryuz David Wilkinson | 2019 | Journal of Magnesium and Alloys2019，7，3： | 4 |

| 12 | In vitro differentiation of human umbilical cord Wharton's jelly mesenchymal stromal cells to insulin producing clusters显示文摘AIM: To investigate the differentiation of human Wharton's jelly derived mesenchymal stromal cells(WJMSCs) to insulin producing clusters(IPC) this study was conducted. METHODS: The umbilical cords samples were collected from full term caesarian section mothers and the WJ-MSCS were cultured from tissue explants in High glucose-Dulbecco's Modified Eagle Medium(H-DMEM); H-DMEM supplemented with 10% fetal bovine serum(FBS) and antibiotics. The expression of CD90, CD44, CD105, CD34 and CD133 as well as osteogenic and adipogenic differentiation of cells in appropriate medium were also evaluated. The cells were differentiated toward IPC with changing the culture medium and adding the small molecules such as nicotinic acid, epidermal growth factor, and exendin-4 during 3 wk period. The gene expression of PDX1, NGN3, Glut2, insulin was monitored by reveres transcription polymerase chain reaction method. The differentiated clusters were stained with Dithizone(DTZ) which confirms the presence of insulin granules. The insulin challenge test(low and high glucose concentration in Krebs-Ringer HEPES buffer) was also used to evaluate the functional properties of differentiated clusters.RESULTS: WJ-MSCS were positive for mesenchymal surface markers(CD90, CD44, CD105), and negative for CD34 and CD133. The accumulation of lipid vacuoles and deposition of calcium mineral in cells were considered as adipogenic and osteogenic potential of WJ-MSCS. The cells also expressed the transcriptional factors such as Nanog and OCT4. During this three step differentiation, the WJ-MSCS morphology was gradually changed from spindle shaped cells in to epithelioid cells and eventually to three dimensional clusters. The clusters expressed PDX1, NGN3, Glut2, and insulin. The cells became bright red color when stained with DTZ and the insulin secretion was also confirmed. In glucose challenge test a significant increase in insulin secretion from 0.91 ± 0.04 μIu/mL(2.8 mmol/L glucose) to to 8.34 ± 0.45 μIu/mL(16.7 mmol/L glucose) was recorded(P < 0.05). The insulin secretion of undifferentiated WJ-MSCS was not changed in this challenge test.CONCLUSION: WJ-MSCs have the ability to differentiate in to islet-like cells in vitro. However, this process needs further optimization in order to generate efficient and functional IPCs. | Seideh Masoomeh Nekoei Negar Azarpira Ladan Sadeghi Sulmaz Kamalifar | 2015 | World Journal of Clinical Cases2015，3，7： | 3 |

| 15 | Sediment contribution from different geologic formations and land uses in an Iranian small watershed,case study显示文摘Many intra and extra problems occurred due to unsustainable human use of natural resources leading to increasing sediment loads in the watersheds.However,few studies have been comprehensively conducted in progressing countries to prioritize sediment sources from different points of views,particularly in some countries like Iran where such valuable information is essential for proper watershed resources management.The present study was therefore planned to assess the importance of potential sediment sources viz.,spatial sources(geologic units) and source types(land use units) in sediment yield in Idelo watershed as one of the important sub-watersheds of Sefidrood large Watershed in Zanjan Province,Iran,using composite fingerprinting.In addition,the results of the sediment fingerprinting approach were compared with those of field measurement data obtained from studying soil erosion types(viz.,sheet,rill and gully erosion).Toward this attempt,16 tracers were detected in different geologic units and land uses and the sediment yielded at the watershed outlet.The results showed that the composite fingerprints of the different geologic units comprising As,N,Cu,Zn,OC and Co tracers could correctly distinguish 86% of the sediment source samples.The red gypsiferous marl contributed 85 percent in sediment yield.In regard to source types,the optimum composite fingerprint encompassed only N and Cu and provided a discriminatory efficiency of 90%.Besides that,the rangelands with 48.8% study area coverage had a significant contribution of 88% in sediment yield.The field measurements confirmed the reliability of results of fingerprinting approach in apportioning watershed scale sediment sources on the base of consistency of the two sets of results.It was also understood from the results,besides successful applicability of composite fingerprinting in assessing the provenance of the sediment yielded at the watershed outlet that the geologic formations and land use types played different roles in sediment yield.Such information helps managers and decision makers to properly regulate appropriate and adaptive management approaches in the study watershed. | Seyed Hamidreza Sadeghi Saeed Najafi Alireza Riyahi Bakhtiari | 2017 | International Journal of Sediment Research2017，32，2： | 3 |

| 20 | Dietary organic acid and fiber sources affect performance,intestinal morphology, immune responses and gut microflora in broilers显示文摘This experiment was designed to investigate the effects of a dietary organic acid(OA) mixture and 2 fiber sources on performance, intestinal morphology, immune responses and gut microflora in broilers. A total of 390 one-day-old broiler chicks(Ross 308) were allocated to 6 dietary treatments with 5 replicate pens and 13 chicks each based on a factorial arrangement(2 x 3) in a completely randomized design. The experiment lasted 42 d. The following experimental diets and as well as their interaction were considered: a basal diet supplemented with or without OA(0 or 1 g/kg) and 2 fiber sources(sugar beet pulp[soluble fiber] or rice hull [insoluble fiber];0 or 30 g/kg). Dietary supplementation of OA increased daily weight gains of broilers across the entire rearing period(P < 0.05). The dietary fibrous materials did not affect the performance of broilers. Antibody titer against influenza disease virus was higher in birds fed diets containing rice hull compared with other experimental groups(P < 0.05). The population of Lactobacillus bacteria was greater in birds fed OA-added diets without or with 30 g/kg rice hull supplementation compared with other experimental groups(P < 0.05). In conclusion, dietary supplemental OA improved performance of broilers, and dietary supplemental OA with rice hull enhanced humoral immune responses. | Sakineh Sabour Sayed A.Tabeidian Ghorbanali Sadeghi | 2019 | Animal Nutrition2019，，2： | 2 |
