| 1 | 采用不同吸附剂从铜电解液中除锑(英文)显示文摘采用不同吸附剂,如活性炭、膨润土、高岭土、树脂、沸石和白沙从铜电解液中去除Sb(Ⅴ),得到不同吸附剂从铜电解液中去除锑(Ⅴ)的吸附容量顺序为:白沙(27)阴离子型树脂(27)沸石(27)高岭土(27)活性炭(27)膨润土。利用FTIR、XRF、XRD、SEM和BET等手段对膨润土进行表征。结果表明:膨润土的比表面积为95 m^2/g,粒度为175 nm;最大去除锑(Ⅴ)的最佳条件为接触时间10 min、4 g膨润土和温度40°C;膨润土吸附锑(Ⅴ)遵守伪二级动力学方程(R^2=0.996,k=9×10^(-5) g/(mg·min))。热力学结果显示,膨润土从铜电解液中吸附锑(Ⅴ)是吸热和自发的过程(ΔG~Θ=-4806 kJ/(mol·K),吸附数据与Freundlich和Langmuir等温线模型吻合。在铜电解液中膨润土具有最大的吸附锑(Ⅴ)容量为10000 mg/g,对于铜电解液中的Zn,Co,Cu和Bi的吸附很低且影响不大。 | Katereh SALARI Saeedeh HASHEMIAN Mohammad Taghi BAEI | 2017 | Transactions of Nonferrous Metals Society of China2017，27，2： | 7 |

| 3 | Isogeometric analysis of free-form Timoshenko curved beams including the nonlinear effects of large deformations显示文摘In the present paper, the isogeometric analysis(IGA) of free-form planar curved beams is formulated based on the nonlinear Timoshenko beam theory to investigate the large deformation of beams with variable curvature. Based on the isoparametric concept, the shape functions of the field variables(displacement and rotation) in a finite element analysis are considered to be the same as the non-uniform rational basis spline(NURBS) basis functions defining the geometry. The validity of the presented formulation is tested in five case studies covering a wide range of engineering curved structures including from straight and constant curvature to variable curvature beams. The nonlinear deformation results obtained by the presented method are compared to well-established benchmark examples and also compared to the results of linear and nonlinear finite element analyses. As the nonlinear load-deflection behavior of Timoshenko beams is the main topic of this article, the results strongly show the applicability of the IGA method to the large deformation analysis of free-form curved beams. Finally, it is interesting to notice that, until very recently, the large deformations analysis of free-form Timoshenko curved beams has not been considered in IGA by researchers. | Seyed Farhad Hosseini Ali Hashemian Behnam Moetakef-Imani Saied Hadidimoud | 2018 | Acta Mechanica Sinica2018，34，4： | 4 |
| 4 | In-vitro bioactivity evaluation and physical properties of an epoxy-based dental sealer reinforced with synthesized fluorine-substituted hydroxyapatite, hydroxyapatite and bioactive glass nanofillers显示文摘The purpose of this study was to evaluate the physical properties and bioactivity potential of epoxy-based dental sealers modified with synthesized bioactive glass(BAG),hydroxyapatite(HA)and fluorine substituted hydroxyapatite(FHA)nanoparticles.The synthesized powders were incorporated at 10%and 20%into the epoxy-based dental sealer.The setting time,flow and solubility and microhardness of the modified and unmodified samples were examined.The bioactivity was evaluated using FESEM-EDX and elemental mapping,ATR-FTIR and XRD.The flow value of all of the experimental groups except the FHA modified samples,was greater than 20 mm.Concerning solubility,no specimens exhibited more than 1%weight loss.The solubility value of the FHA groups was statistically significant lower than other groups(p≤0.001).The mean hardness values of all of the modified samples were significantly higher than the unmodified group(p≤0.001).Regarding bioactivity,in vitro study revealed that after 3 days immersion in SBF a compact and continuous calcium phosphate layer formed on the surface of epoxy sealers containing BAG and HA nanoparticles.Based on these results,the addition of BAG and HA nanoparticles did not adversely alter the physical properties of epoxy sealers.Additionally,they improved the in vitro bioactivity of the epoxy sealer. | Bahaa Abdulrazzaq Jerri Al-Bakhsh Farhad Shafiei Atieh Hashemian Kiana Shekofteh Behnam Bolhari Marjan Behroozibakhsh | 2019 | Bioactive Materials2019，4，1： | 3 |
| 5 | 白内障摘除术后不同后囊膜混浊的发生率和分布(英文)显示文摘目的:评价院内白内障手术和人工晶状体(IOL)植入术后不同类型PCO的频率和分布。方法:本横断、观察和描述性研究包括200名2003/2007年间提交白内障手术的患者。男123名,女77名,年龄43~77(平均62.4)岁之间。患者平均随访期为23(16~60)mo。随访期间通过一份问卷收集数据并使用SPSS软件输入计算机。使用方差分析和卡方检验分析。结果:不同类型的后囊膜混浊,包括纤维化(63%),残留上皮细胞增殖(15%)和混合型(22%)。由PCO引起的视力减退发生的平均时间为19.3(3~48)mo。年轻患者白内障手术后视力明显提高(P=0.0001),但PCO的发生率也多些。在老年组,纤维化后囊膜混浊明显多见,而混合型混浊是最不普遍的(P=0.016)。结论:目前的研究并没有测定PCO发生的任何特定的危险因素,最常见的类型是纤维化。所有的病例都经历定性和定量的视力减退,其中一些需要YAG激光晶状体囊膜切开术治疗,比较昂贵并有其自身的并发症。 | Abolghasem Rastegar Manijah Mahdavi Zahra Hashemian | 2010 | 国际眼科杂志2010，10，1： | 2 |

| 7 | Ocular higher-order aberrations and mesopic pupil size in individuals screened for refractive surgery显示文摘AIM: To study the distribution of ocular higher-order aberrations(HOAs) and mesopic pupil size in individuals screened for refractive surgery. · METHODS: Ocular HOAs and mesopic pupil size were studied in 2 458 eyes of 1 240 patients with myopia, myopic astigmatism and compound myopic astigmatism and 215 eyes of 110 patients with hyperopia, hyperopic astigmatism and compound hyperopic astigmatism using the Zywave aberrometer (Busch& Lomb). All patients had correctable refractive errors without a history of refractive surgery or underlying diseases. Root-mean-square values of HOAs, total spherical aberration, total coma and mesopic pupil size were analyzed. Ocular HOAs were measured across a ≥ 6.0 mm pupil, and pupil size measurements were performed under the mesopic condition. · RESULTS: The mean values of HOAs, total spherical aberration and total coma in the myopic group were 0.369 μm, ±0.233, 0.133±0.112μm and 0.330±0.188μm, respectively. In the hyperopic group the mean values of HOAs, total spherical aberration and total coma were 0.418μm±0.214, 0.202±0.209μm and 0.343±0.201μm, respectively. Hyperopes showed greater total HOAs (P <0.01) and total spherical aberration (P <0.01) compared to myopes. In age-matched analysis, only the amount of total spherical aberration was higher in the hyperopic group (P =0.05). Mesopic pupil size in the myopic group was larger (P ≤0.05). · CONCLUSION: The results suggested that significant levels of HOAs were found in both groups which are important for planning refractive surgeries on Iranians. There were significantly higher levels of total spherical aberration in hyperopes compared to myopes. Mesopic pupil size was larger in myopic group. | Seyed Javad Hashemian Mohammad Soleimani Alireza Foroutan Mahmood Joshaghani Mohammad Jafar Ghaempanah Mohammad Ebrahim Jafari Mehdi Yaseri | 2012 | International Journal of Ophthalmology(English edition)2012，5，2： | 2 |
