| 1 | Hot Deformation Characteristics of 34CrMo4 Steel显示文摘The 34CrMo4(AISI 4130)steel is extensively utilized in the compressed natural gas cylinders.Due to the importance of thermomechanical processing in the production of these cylinders,the dynamic recrystallization(DRX)characteristics of 34CrMo4 steel were investigated.The effect of hot deformation parameters such as temperature and strain rate on the dynamic restoration processes of a 34CrMo4 alloy was studied.Hot compression tests were performed in the temperature range of 900 to 1100 ℃ and the strain rate range of 0.001 to 0.1 s-1.Hot workability of this alloy has been analyzed by employing flow localization parameter.The flow curves observed are typical of occurrence of dynamic recrystallization and have exhibited single or multiple peaks in flow stress curve before reaching steady state,depending on the temperature and strain rates.The flow stress decreases with the increase of deformation temperature and the decrease of strain rate.Finally the activation energy obtained in this research is 490.749 kJ/mol. | S V Sajadi Far M Ketabchi M R Nourani | 2010 | Journal of Iron and Steel Research(International)2010，17，12： | 4 |
| 2 | Sciatic nerve injury alters the spatial arrangement of neurons and glial cells in the anterior horn of the spinal cord显示文摘The spatial arrangement of the cell is important and considered as underlying mechanism for mathematical modeling of cell to cell interaction.The ability of cells to take on the characteristics of other cells in an organism,it is important to understand the dynamical behavior of the cells.This method implements experimental parameters of the cell-cell interaction into the mathematical simulation of cell arrangement.The purpose of this research was to explore the three-dimensional spatial distribution of anterior horn cells in the rat spinal cord to examine differences after sciatic nerve injury.Sixteen Sprague-Dawley male rats were assigned to control and axotomy groups.Twelve weeks after surgery,the anterior horn was removed for first-and second-order stereological studies.Second-order stereological techniques were applied to estimate the pair correlation and cross-correlation functions using a dipole probe superimposed onto the spinal cord sections.The findings revealed 7% and 36% reductions in the mean volume and total number of motoneurons,respectively,and a25% increase in the neuroglial cell number in the axotomized rats compared to the control rats.In contrast,the anterior horn volume remained unchanged.The results also indicated a broader gap in the pair correlation curve for the motoneurons and neuroglial cells in the axotomized rats compared to the control rats.This finding shows a negative correlation for the distribution of motoneurons and neuroglial cells in the axotomized rats.The cross-correlation curve shows a negative correlation between the motoneurons and neuroglial cells in the axotomized rats.These findings suggest that cellular structural and functional changes after sciatic nerve injury lead to the alterations in the spatial arrangement of motoneurons and neuroglial cells,finally affecting the normal function of the central nervous system.The experimental protocol was reviewed and approved by the Animal Ethics Committee of Shahid Beheshti University of Medical Sciences(approval No.IR.SBMU.MSP.REC1395.375) on October 17,2016. | Ali Rashidiani-Rashidabadi Mohammad Hassan Heidari Ensieh Sajadi Fatemeh Hejazi Fatemeh Fadaei Fathabady Yousef Sadeghi Abbas Aliaghaei Amir Raoofi Mohammad-Amin Abdollahifar Reza Mastery Farahni | 2019 | Neural Regeneration Research2019，14，10： | 2 |

| 5 | 采用积雪草树叶提取物生物合成二氧化镁纳米粒子负载的铜纳米颗粒用于高效催化还原有机染料和芳香硝基化合物(英文)显示文摘本文设计了一个经济、绿色的新型方法,采用积雪草树叶提取物作为自然的还原剂,在不使用稳定剂或表面活性剂的情况下合成了MnO_2纳米粒子负载的Cu纳米颗粒(CuNPs).该合成过程环境友好,且避免使用有毒的还原剂.树叶提取物中的酚羟基将溶液中的Cu^(2+)还原为Cu NPs,后者再稳定在MnO_2 NPs表面.采用X射线衍射、透射电镜、场发射扫描电镜、能量散射谱和红外光谱对所得Cu/MnO_2纳米复合物进行了表征.结果表明,该材料可用作高活性、高效可重复使用的多相催化剂,用于室温水溶液NaBH_4存在下刚果红、罗丹明B和亚甲基蓝,以及硝基化合物,如2,4二硝基苯肼和4-硝基苯酚的催化还原.Cu/MnO_2纳米复合物的高稳定性可使其被分离出来,重复使用数次而活性无明显下降. | Mahmoud Nasrollahzadeh Mohaddeseh Sajjadi S.Mohammad Sajadi | 2018 | Chinese Journal of Catalysis2018，39，1： | 1 |

| 10 | Preparation of a pH-sensitive pantoprazole-imprinted polymer and evaluation of its drug-binding and-releasing properties显示文摘The aim of this work was to synthesize a pantoprazole-imprinted polymer(MIPs)and study its binding and release properties in an aqueous media.Methacrylic acid(MAA),methacrylamide(MAAM),hydroxyethyl methacrylate(HEMA),and 4-vinyl pyridine(4VP)were tested as functional monomers.Different solvents were also applied as polymerization media under heat or UV radiation.The optimized MIP was prepared in chloroform as a solvent,4-vinyl pyridine as a functional monomer,and ethylene glycole dimethacrylate(EGDMA)as a crosslinker monomer under UV irradiation.Binding and release properties of MIP were studied in comparison with a non-imprinted polymer(NIP)in aqueous media,at different pH values.The protective effect of polymer for drugs against acidic conditions was evaluated at pH 2.Results indicated that the MIP had superior binding properties compared to NIP for pantoprazole.The percentage of drug released from MIP was significantly less than from NIP at all pH values,which was attributed to the presence of imprinted cavities in the MIP matrix.MIP also had a stronger protective effect for pantoprazole in acidic media,in comparison with NIP. | MOHAJERI Seyed Amin SAJADI TABASSI Sayyed Abolghasem HASSANPOUR MOGHADAM Maryam MOHAJERI Seyed Ahmad | 2014 | Science China Chemistry2014，57，6： | 1 |
