| 1 | Using Pd-salen complex as an efficient catalyst for the copper-and solvent-free coupling of acyl chlorides with terminal alkynes under aerobic conditions显示文摘The palladium-salen complex palladium(Ⅱ) N,N'-bis{[5-(triphenylphosphonium)-methyl]salicylidene}-l,2-ethanediamine chloride was found to be a highly active catalyst for the copper- and solvent-free coupling reaction of terminal alkynes with different acyl chlorides in the presence of triethylamine as base, giving excellent ynones under aerobic conditions. | Mohammad Bakherad Amir Hossein Amin Ali Keivanloo Bahram Bahramian Mersad Raessi | 2010 | Chinese Chemical Letters2010，21，6： | 2 |
| 2 | Simultaneous effects of mesh refinement, grid configuration and wall boundary condition on prediction of pressure gradients and velocity profiles of microparticles in a conical fluidized bed显示文摘The reliability and accuracy of numerical results of microparticle fluidization in a conical bed, affected simultaneously by mesh refinement, the grid configuration and the wall boundary condition (BC), are analyzed. Specifically, pressure gradients and velocity profiles of titania powder are studied for a conical bed. The Gidaspow drag correlation and different wall BCs are considered using a Eulerian-Eulerian two-fluid model. Predictions of the pressure fluctuation, power spectra of the corresponding pressure fluctuations, bed pressure drop, minimum fluidizati on veloc ity, axial solid velocity, bed expansi on ratio, and particle size distribution are compared with experimental data. Mesh sensitivity analysis using hexahedral and tetrahedral cells with a un iform mesh and n ear-wall mesh refineme nr is con ducted to inv estigate the effects of mesh configurations in estimating particle flow patterns. Simulations show that significant savings in terms of computational time are realized by choosing a uniform mesh while the hexahedral structure, the near-wall mesh refinement, and the free-slip BC give the closest fit to the experimental data. | Alireza Bahramian | 2019 | Particuology2019，17，2： | 2 |
| 3 | Osteochondral autograft transfer (mosaicplasty) for treatment of patients with osteochondral lesions of talus显示文摘Purpose:Osteochondral lesion of talus(OLT)is one of the common causes of ankle pain.This disorder is common in young athletes after ankle injury.There are various therapeutic options.One of the options is mosaic plasticizer.The purpose of this study was to investigate the effect of mosaicplasty on improvement of symptoms of patients with osteochondral lesions of talus.Methods:Nineteen patients with osteochondral lesions of talus participated in this study,who were treated with mosaicplasty.Before and after treatment,pain(visual analogue scale),function(American Orthopaedic Foot and Ankle Society),range of motion and radiographic signs were evaluated.Results:The results of this study showed that mosaicplasty could significantly reduce pain,increase function and improve radiographic symptoms.The range of motion increased after treatment,which was not significant.Conclusion:We can confirm the effect of mosaicplasty on the improvement of patients with osteochondral lesions of the ankle,suggesting it as a treatment option. | Amir Sabaghzadeh Fateme Mirzaee Heydar Shahriari Rad Fateme Bahramian Ardeshir Alidousti Hamidreza Aslani | 2020 | Chinese Journal of Traumatology2020，23，1： | 2 |
