| 1 | Organic solvent-and phase transfer catalyst-free oxidation of cyclohexanol to cyclohexanone with dilute H_2O_2显示文摘The oxidation of cyclohexanol to cyclohexanone with 30% aqueous hydrogen peroxide by using peroxotung-state complexes formed in situ from sodium tungstate di-hydrate and various bidentate organic ligands as the catalysts, without organic solvents, halide and phase transfer catalyst has been carried out. The influence of 13 ligands on the oxidation is investigated. The maximum yield of cyclohexanone is obtained when using 1,10-phenanthroline (96%) and oxalic acid (95%) as the ligand. Very high yields (around 90%) have also been obtained for the instances of using salicylic acid, 3,5-dibromosalicylic acid, and 8-hydro- xylquino-line as ligands. A research to improve the reaction condition using cheap oxalic acid as the ligand indicates that the optimum condition is that the reaction mixture with a molar ratio of cycohexanol:tungstate dihydrate:oxalic acid: 30% H2O2=100:2:2:120 was stirred at 85-90℃ for 12 h. | WEI Junfa, SHI Xianying, HE Diping & ZHANG MinSchool of Chemistry and Material Science, Shaanxi Normal University, Xi’an 710062, China | 2002 | Chinese Science Bulletin2002,47,24: | 3 |

| 6 | Association of immunoglobulin G4-related disease with a family history of malignancy:A retrospective study of 168 cases显示文摘Objective:Immunoglobulin G4-related disease(IgG4-RD)is a systemic immune-mediated fibroinflammatory condition.Previous studies have indicated relationships between malignancy and autoimmunity.This retrospective cohort study aimed to determine IgG4-RD incidence and clinical features in patients with a family history of malignancy.Methods:To analyze the relationship between IgG4-RD and family history of malignancy,we reviewed IgG4-RD patients with a family history of malignancy diagnosed in various departments in West China Hospital,Sichuan University from December 2012 to September 2019.Clinical data and laboratory features were compared between IgG4-RD patients with and without a family history of malignancy.Results:Among 168 enrolled patients with IgG4-RD,22(13.1%)had a family history of malignancy.The most frequently involved system in family members with malignancy was the digestive system(38.5%).Among patients with a family history of malignancy,the most frequently involved organs in IgG4-RD were the pancreas(31.9%)and lymph nodes(31.9%).Age at symptom onset was older in IgG4-RD patients with a family history of malignancy than in patients without a family history of malignancy(50–59 years:36.3%vs.16.4%,p=0.0393).Hemoglobin(p=0.0172)and albumin(p=0.0247)levels were higher and globulin(p=0.0232)levels were lower in patients with a family history of malignancy.Conclusions:Our findings suggest that a family history of malignancy may be associated with IgG4-RD development.We hypothesize that genetic susceptibility may be involved in the pathogenesis of IgG4-RD. | Diping Hu Yanhong Li Yu Zhou Yubin Luo Lu Cheng Chunyu Tan Qiuping Zhang Yi Zhao Yi Liu | 2021 | Rheumatology & Autoimmunity2021,1,2: | 1 |
| 7 | Non-linear Dynamics of Inlet Film Thickness during Unsteady Rolling Process显示文摘The inlet film thickness directly affects film and stress distribution of rolling interfaces. Unsteady factors, such as unsteady back tension, may disturb the inlet film thickness. However, the current models of unsteady inlet film thickness lack unsteady disturbance factors and do not take surface topography into consideration. In this paper, based on the hydrodynamic analysis of inlet zone an unsteady rolling film model which concerns the direction of surface topography is built up. Considering the small fluctuation of inlet angle, absolute reduction, reduction ratio, inlet strip thickness and roll radius as the input variables and the fluctuation of inlet film thickness as the output variable, the non-linear relationship between the input and output is discussed. The discussion results show that there is 180° phase difference between the inlet film thickness and the input variables, such as the fluctuant absolute reduction, the fluctuant reduction ratio and non-uniform inlet strip thickness, but there is no phase difference between unsteady roll radius and the output. The inlet angle, the steady roll radius and the direction of surface topography have significant influence on the fluctuant amplitude of unsteady inlet film thickness. This study proposes an analysis method for unsteady inlet film thickness which takes surface topography and new disturbance factors into consideration. | FU Kuo ZANG Yong GAO Zhiying QIN Qin WU Diping | 2016 | Chinese Journal of Mechanical Engineering2016,29,3: | 1 |

| 11 | Physical principle of wind erosion on sandy land surface in southern Beijing显示文摘The endangerment of aeolian sand is one of the most serious eco-environmental problems facing the southern suburb of Beijing. To control wind erosion is thus a matter of great urgency. This paper chooses typical land-use types, i.e., cultivated land, wild grassland, drifting sandy land, etc. based on the fixed experimental observation and quantitative analysis, to conduct studies on the principles and characteristics of aeolian activities and measures controlling wind erosion in Daxing District of Beijing. The results show that: the near ground wind velocity yielded the logarithmic distribution with height; there are significant differences among different ground cover roughness; there are significant differences in the corresponding friction velocities caused by different properties of the underlying surface; there are differences in the threshold wind velocities speed in different land use types; and there are minus exponential relations between the sediment discharge percentage and the height at a range of 0–20 cm air flow layer. Different land use types result in various degrees of coarse component. There is a significant exponential relation between sediment transport concentration and wind velocity. | YUE Depeng LIU Yongbing WANG diping LI Hailong CUI Weijia | 2006 | Journal of Geographical Sciences2006,16,4: | 1 |

| 13 | Intelligent fire information system based on 3D GIS显示文摘Background This work aims to build a comprehensive and effective fire emergency management system based on the Internet of Things(IoT)and achieve an actual intelligent fire rescue.A smart fire protection information system was designed based on the IoT.A detailed analysis was conducted on the problem of rescue vehicle scheduling and the evacuation of trapped persons in the process of fire rescue.Methods The intelligent fire visualization platform based on the three-dimensional(3D)Geographic Information Science(GIS)covers project overview,equipment status,equipment classification,equipment alarm information,alarm classification,alarm statistics,equipment account information,and other modules.The live video accessed through the visual interface can clearly identify the stage of the fire,which facilitates the arrangement of rescue equipment and personnel.The vehicle scheduling model in the system primarily used two objective functions to solve the Pareto Non-Dominated Solution Set Optimization:emergency rescue time and the number of vehicles.In addition,an evacuation path optimization method based on the Improved Ant Colony(IAC)algorithm was designed to realize the dynamic optimization of building fire evacuation paths.Results The experimental results indicate that all the values of detection signals were significantly larger in the smoldering fire scene at t=17s than the initial value.In addition,the probability of smoldering fire and the probability of open fire were relatively large according to the probability function of the corresponding fire situation,demonstrating that this model could detect fire.Conclusions The IAC algorithm reported here avoided the passages near the fire and spreading areas as much as possible and took the safety of the trapped persons as the premise when planning the evacuation route.Therefore,the IoT-based fire information system has important value for ensuring fire safety and carrying out emergency rescue and is worthy of popularization and application. | Jinxing HU Zhihan LV Diping YUAN Bing HE Dongmei YAN | 2023 | Virtual Reality & Intelligent Hardware2023,5,2: | 0 |
| 14 | Functionalized TiO_2@ZrO_2@Y_2O_3:Eu^(3+) core-multishell microspheres and their photoluminescence properties显示文摘TiO2@ZrO2@Y2O3:Eu3+composite particles with a core-multishell structure were synthesized through the combination of a layer-by-layer(LBL) self-assembly method and a sol-gel process.The obtained samples were characterized with scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD),and fluorescence spectrophotometry.The results showed that the composite particles had a core-multishell structure,spherical morphology,and a narrow size distribution.The presence of a ZrO2 layer on the TiO2 core can effectively prevent the reaction between the TiO2 core and a Y2O3 shell;the temperature for the reaction between the TiO2 core and the Y2O3 shell in the TiO2@ZrO2@Y2O3:Eu core-multishell phosphor can be elevated by 300℃ compared to that for TiO2@Y2O3:Eu.Upon excitation of the core-multishell particles in the ultraviolet(254 nm),the Eu^(3+)ion in the Y2O3:Eu^(3+) shell shows its characteristic red emission(611 nm,~5D0→~7F2),and the photoluminescence(PL) intensity of the phosphor with the core-multishell structure was obviously greater than that of the core-shell TiO2@Y2O3:Eu phosphor. | Jiali Sun Xuan Gao Diping He Juan Chen Xin Meng Qiao Zhang Lili Shen Huan Jiao | 2013 | Particuology2013,11,6: | 0 |
