| 1 | The Influence of Phacoemulsification on Corneal Endothelia Cells at Varying Blood Glucose Levels显示文摘Purpose:To investigate the influence of phacoemulsification on corneal endothelial cells in diabetes patients and normal controls. Methods:Phacoemulsification and intraocular lens implantation were performed on 75 patients with diabetic cataract (126 eyes) who were divided into two groups: Trial group 1 (Glu≤6 mmol/L); Trial group 2 (Glu 6-10 mmol/L) and 65 nondiabetic controls (112 eyes).The density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia were measured before surgery and 1 day,1 month and 3 months postoperatively. Results: There was no statistical difference in the density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia prior to phacoemulsification.(P>0.05) between the three groups.The density and percentage of hexagonal cells of the corneal endothelia decreased significantly after surgery in all three groups(P<0.05),while the Coefficient of variation increased in all groups(P<0.05). The rate of loss of corneal endothelial cells in the diabetic groups was significantly higher than for the control group (P<0.05), the percentage of hexagonal cells in the diabetic groups was significantly lower than for the control group (P<0.05), and the coefficient of variation in the diabetic groups was significantly higher than for the control group (P<0.05) at 1 day, 1 month and 3 months post-operatively. There was no statistical difference between the two diabetic groups in terms of these post-operative measurements. Conclusion:The corneal endothelium of diabetic patients is more prone to damage from phacoemulsification. It is advisable to evaluate the corneal endothelium routinely prior to phacoemulsification, particularly in diabetic persons. | RuiMing Yang Xiangyin Sha Mingbing Zeng Yingqian Tan Yu Zheng Feihong Fan | 2011 | Eye Science2011，26，2： | 14 |
| 2 | Unraveling the influence of interface defects on antimony trisulfide solar cells显示文摘Antimony trisulfide(Sb_(2)S_(3)) solar cells suffer from large open circuit voltage deficits due to their intrinsic defects which limit the power conversion efficiency.Thus,it is important to elucidate these defects’ origin and defects at the interface.Here,we discover that sulfide radical defects have a significant impact on the performance of Sb_(2)S_(3)solar cells.Moreover,it has been illustrated that these defects at the CdS/Sb_(2)S_(3)interface can be reduced by optimizing the deposition process.A trap distribution model is used to quantify the defect density at the CdS/Sb_(2)S_(3)interface.It shows that the interface defects can be reduced by24% by improving the deposition process.This work reveals the importance of interface defects and guides the future optimization of Sb_(2)S_(3)solar cells. | Hongyi Chen Cheng Wang Shaoying Wang Ruiming Li Yan Zeng Zhe Li Zhengwei Ou Qianqian Lin Jianmin Li Ti Wang Hongxing Xu | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 3 | Low-temperature dry reforming of methane tuned by chemical speciations of active sites on the SiO_(2) and γ-Al_(2)O_(3) supported Ni and Ni-Ce catalysts显示文摘The cognition of active sites in the Ni-based catalysts plays a vital role and remains a huge challenge in improving catalytic performance of low temperature CO_(2) dry reforming of methane(LTDRM).In this work,typical catalysts of SiO_(2) and γ-Al_(2)O_(3) supported Ni and Ni-Ce were designed and prepared.Importantly,the difference in the chemical speciations of active sites on the Ni-based catalysts is revealed by advanced characterizations and further estimates respective catalytic performance for LTDRM.Results show that larger[Ni0-]particles mixed with[Ni-O-Sin])species on the Ni/SiO_(2)(R)make CH_(4) excessive decomposition,leading to poor activity and stability.Once the Ce species is doped,however,superior activity(59.0%CH_(4) and 59.8%CO_(2) conversions),stability and high H_(2)/CO ratio(0.96)at 600℃ can be achieved on the Ni-Ce/SiO_(2)(R),in comparison with other catalysts and even reported studies.The improved performance can be ascribed to the formation of integral([Ni0_(n))]-[CeⅢ-□-CeⅢ])species on the Ni-Ce/SiO_(2)(R)catalyst,containing highly dispersed[Ni]particles and rich oxygen vacancies,which can synergistically establish a new stable balance between gasification of carbon species and CO_(2) dissocia-tion.With respect to Ni-Ce/γ-Al_(2)O_(3)(R),the Ni and Ce precursors are easily captured by extra-framework Al_(n)-OH groups and further form stable isolated([Ni0_(n))]-[Ni-O-Al_(n)])and[CeⅢ-O-Al_(n)]species.In such a case,both of them preferentially accelerate CO_(2) adsorption and dissociation,causing more car-bon deposition due to the disproportionation of superfuous CO product.This deep distinguishment of chemical speciations of active sites can guide us to further develop new efficient Ni-based catalysts for LTDRM in the future. | Yimin Zhang Ruiming Zeng Yun Zu Linhua Zhu Yi Mei Yongming Luo Dedong He | 2022 | Chinese Journal of Chemical Engineering2022，35，8： | 0 |
