5Oxygen-assisted spinodal structure achieves 1.5 GPa yield strength in a ductile refractory high-entropy alloy显示文摘Refractory high-entropy alloys(RHEAs)with room-temperature ductility are drawing growing attention for potential high-temperature applications.However,the most widely used metallurgical mechanisms appear weak in optimizing their strength and ductility.Here,we report that the nanoscale spinodal struc-ture in Ti_(41)V_(27)Hf_(15)Nb_(15)O_(2)leads to the highest tensile yield strength(∼1.5 GPa)among the existing RHEAs and good elongation of∼12%.With the aid of thermodynamic calculations,we show that oxygen plays a dominant role in controlling the formation of the spinodal structure by influencing the spinodal gap of the Ti-V-Hf-Nb system.Exploring the atomic structure of the spinodal structure(β+β^(∗)),we showed that the large lattice misfit of the spinodal phases is mainly responsible for the excellent strengthen-ing effect while the planar to wavy dislocation glide mode transition accounts for the retained ductility.This work provides a novel strategy to improve the mechanical properties of the RHEAs and deepens the understanding of their phase stabilities.Dingcong Cui Yuyu Zhang Linxiang Liu Yue Li Lei Wang Zhijun Wang Junjie Li Jincheng Wang Feng He 2023Journal of Materials Science & Technology2023,,26:1
6Pacific decadal oscillation impact on East China precipitation and its imprint in new geological documents显示文摘This paper briefly introduces the history of the study of the Pacific decadal oscillation(PDO) and explores the relationship between the PDO and sediment grain size from two typical sediment cores from the lower Changjiang(Yangtze River) and Huanghe(Yellow River) estuaries. It is found that the median grain sizes of both cores exhibit relatively high correlation with the PDO. This is because the PDO causes interdecadal variability of precipitation in the East Asia Monsoon region, thus changing the hydrodynamics in both the Changjiang and Huanghe catchments, eventually resulting in variation of sediment grain size. Our analysis also revealed that during different phases of the PDO, the sediment grain size of the Changjiang and Huanghe estuaries showed different variations in cold and warm PDO phases. This is related to movement of the precipitation center driven by the shift in different PDO phases. Moreover, we compared more high resolution geological proxies with the PDO, including stalagmites and tree rings, in East China over the past century. The results indicate that variations of studied geological proxies are generally well correlated with the PDO but have some differences. Finally, longer variations of sediment grain sizes in the Changjiang and Huanghe estuaries are compared with a reconstructed PDO over the last 200 years;sediment grain sizes were still correlated with the PDO, implying that sediment grain size may be used as a new proxy for studying the long-term behavior of the PDO. This result supports previous knowledge of the PDO impact on East China climate evolution and offers a new proxy for further PDO study. Our study will improve paleoenvironment reconstruction in East China on a decadal time scale and benefit future climatic predictions.Jiahui YAO Linxiang XIAO Mengmeng GOU Chao LI Ergang LIAN Shouye YANG 2018Science China Earth Sciences2018,61,4:1
7Biopolymer passivation for high-performance perovskite solar cells by blade coating显示文摘Thin films of perovskite deposited from solution inevitably introduce large number of defects,which serve as recombination centers and are detrimental for solar cell performance.Although many small molecules and polymers have been delicately designed to migrate defects of perovskite films,exploiting credible passivation agents based on natural materials would offer an alternative approach.Here,an ecofriendly and cost-effective biomaterial,ploy-L-lysine(PLL),is identified to effectively passivate the defects of perovskite films prepared by blade-coating.It is found that incorporation of a small amount(2.5 mg mL^(-1))of PLL significantly boosts the performance of printed devices,yielding a high efficiency of 19.45% with an increase in open-circuit voltage by up to 100 mV.Density functional theory calculations combined with X-ray photoelectron spectroscopy reveal that the functional groups(-NH2,-COOH)of PLL effectively migrate the Pb-I antisite defects via Pb-N coordination and suppress the formation of metallic Pb in the blade-coated perovskite film.This work suggests a viable avenue to exploit passivation agents from natural materials for preparation of high-quality perovskite layers for optoelectronic applications.Shudi Qiu Xin Xu Linxiang Zeng Zhen Wang Yijun Chen Culling Zhang Chaohui Li Jinlong Hu Tingting Shi Yaohua Mai Fei Guo 2021Journal of Energy Chemistry2021,30,3:1

10Purified protein derivative skin testing on HIV/AIDS patients and logistic regression analysis of its risk factors显示文摘Objective: To understand the reactivity of purified protein derivative skin test(PPD test) in HIV-infected persons and to determine the influential factors associated with PPD. Methods: 174 HIV/AIDS patients registered in the local center for disease control and prevention(CDC) participated this study from April to June in 2006. Questionnaire,CD4 count and thoracic roentgenogram were performed for all participants. Results: In this study, response rate of questionnaires was 83.65%. The majority of these participants had a different degree of immunodeficiency that accounted for 93.64%. Female patients had a higher CD4 count than that of males. The total positive rate of PPD was 38.15%. Analysis of single factor in our study indicated that CD4 count, previous tuberculosis history, tuberculosis contact history and thoracic roentgenogram manifestation of patients were related to their PPD diameters. Further analysis of multiple factors also supports the previous conclusion that CD4 count and previous tuberculosis history of patients were risk factors in the PPD test. Conclusion: The PPD test of HIV/AIDS patients could be affected by several factors. For persons infected with HIV, the confirmation of latent tuberculosis infection (LTBI) should be considered the combination effect of previous MTB infection and body cellular immune function.Fengren Liu Jianjun Ye Changfu Xiong Jiguo Yin Weihua He Gaobo Li Dingyuan Zha Linxiang Ye 2007Journal of Nanjing Medical University2007,21,3:0
11Calculating single layer production contribution of heavy oil commingled wells by analysis of aromatic parameters in whole-oil GC-MS显示文摘Traditional fluid production profile logging is not usually suitable for heavy-viscous crude oil wells. Biodegradation of heavy oil can lead to the loss of n-alkanes, and the use of chromatogram fingerprint techniques in studying the production contributions of single layers in heavy oil commingled wells has limitations. However, aromatic compounds are relatively well preserved. We took the heavy oil commingled wells of small layers NG55 and NG61 in the ninth area of the Gudong oil field as examples. Based on the principle of chromatography, the whole-oil GC-MS was used, and the aromatic parameters which have a strongly linear relationship with the ratio of mixed two end member oils were verified and selected in laboratory. Studies showed that the ratio of(1, 4, 6-+ 2, 3, 6-trimethylnaphthalene) to 1, 2, 5-trimethylnaphthalene has a strongly linear relationship with the ratio of the mixed two end member oils(R2=0.992). The oil contributions from single layers NG55 and NG61 in six commingled heavy oil wells were calculated using established charts and this relationship. The calculated results are consistent with the results of long period dynamic monitoring and logging interpretation in the study area and can provide a scientific basis for monitoring production performance and hierarchical management of reservoirs. The study provides a new geochemical method for calculation of the contributions of single layers in heavy oil commingled wells when conventional fluid production profile logging is not suitable.Xu Yaohui Ma Li Li Linxiang Cui Wenfu Cheng Xiaowei Wang Xiaoping 2014Petroleum Science2014,11,1:0
