| 1 | A new understanding of the effect of Cr on the corrosion resistance evolution of weathering steel based on big data technology显示文摘In this work,we studied the effect of Cr element on the corrosion resistance evolution of weathering steel based on corrosion big data technology.It suggested that corrosion big data technology is suitable for evaluation of the effect of microalloying Cr element on the corrosion evolution behavior of weathering steel.New understandings prove that the effect of Cr on the corrosion process is dynamic rather than static,the processes is affected by both of the environmental factors and the electrochemical or chemical reactions in the rust layer.Besides,Cr element has both beneficial effect and detrimental effect on the corrosion resistance of weathering steel.The beneficial effect is that the general corrosion resistance of Cr-additional steel is better than that of Cr-free steel,while the detrimental effect is that localized corrosion is intensified as the increase of Cr content in the Cr-additional steel. | Xiaojia Yang Ying Yang Meihui Sun Jinghuan Jia Xuequn Cheng Zibo Pei Qing Li Di Xu Kui Xiao Xiaogang Li | 2022 | Journal of Materials Science & Technology2022，，9： | 12 |
| 2 | Distinct beneficial effect of Sn on the corrosion resistance of Cr-Mo low alloy steel显示文摘In this work,the beneficial effect of Sn addition on the corrosion resistance mechanism of Cr-Mo low alloy steel was studied.Results demonstrated that Sn improves the corrosion resistance of the steel matrix mainly by influencing the microstructural transformation.Sn addition and the synergistic effect of Sn,Cr,and Mo promote the formation of α-FeOOH,SnO_(2),SnO,Cr(OH)_(3),and molybdates,lead to the improved protection and stability of the rust layer.This synergistic effect also endows the inner rust layer with cation selectivity,preventing the further penetration of Cl-and inhibiting the localized corrosion of steel. | Meihui Sun Xiaojia Yang Cuiwei Du Zhiyong Liu Yong Li Yumin Wu Hongyu San Xiandong Su Xiaogang Li | 2021 | Journal of Materials Science & Technology2021，，22： | 6 |
| 3 | A micro-nano optogenetic system based on probiotics for in situ host metabolism regulation显示文摘Genetically engineered bacteria have aroused attention as micro-nano drug delivery systems in situ.However,conventional designs of engineered bacteria usually function constantly or autonomously,which might be non-specific or imprecise.Therefore,designing and optimizing in situ control strategy are important methodological progress for therapeutic researches of intestinal engineered bacteria.Here,a micro-nano optogenetic system based on probiotic was developed combining microelectronics,nanotechnology,and synthetic biology to achieve in situ controllable drug delivery.Firstly,optogenetic engineered Lactococcus lactis was orally administrated in the intestinal tract.A wearable optical device was designed to control optical signals remotely.Then,L.lactis could be customized to secrete peptides according to optical signals.As an example,optogenetic L.lactis system can be constructed to secrete glucagon-like peptide-1(GLP-1)under the control of the wearable optical device to regulate metabolism.To improve the half-life of GLP-1 in vivo,Fc-domain fused GLP-1 was optimally used.Using this strategy,blood glucose,weight,and other features were well controlled in rats and mice models.Furthermore,upconversion microcapsules were introduced to increase the excitation wavelength of the optogenetic system for better penetrability.This strategy has biomedical potential to expand the toolbox for intestinal engineered bacteria. | Xinyu Zhang Ning Ma Wei Ling Gaoju Pang Tao Sun Jing Liu Huizhuo Pan Meihui Cui Chunli Han Chun Yang Jin Chang Xian Huang Hanjie Wang | 2023 | Nano Research2023，16，2： | 2 |
| 4 | Material patterning on substrates by manipulation of fluidic behavior显示文摘Patterned materials on substrates are of great importance for a wide variety of applications.In solution-based approaches to material patterning;fluidic flow is inevitable.Here we demonstrate not only the importance of fluidic behavior but also the methodology of engineering the flow pattern to guide the material crystallization and assembly.We show by both experiment and simulation that substrate heating;which is generally used to accelerate evaporation,produces irregular complex vortexes.Instead;a top-heating-bottom-cooling(THBC)set-up offers an inverse temperature gradient and results in a single Marangoni vortex,which is desired for ordered nanomaterial patterning near the contact line.We then realize the fabrication of large-scale patterns of iodide perovskite crystals on different substrates under THBC conditions.We further demonstrate that harnessing the flow behavior is a general strategy with great feasibility to pattern various functional materials ranging from inorganic;organic,hybrid to biological categories on different substrates,presenting great potential for practical applications. | Yitan Li Hao Wang Henglu Xu Shiting Wu Xuemei Li Jiapeng Yu Chaoyu Huang Zeyao Zhang Hao Sun Lu Han Meihui Li Anyuan Cao Zhenhai Pan Yan Li | 2019 | National Science Review2019，6，4： | 0 |
| 5 | An investigation of long-term outcome of rabbit anti-thymocyte globulin and cyclosporine therapy for pediatric severe aplastic anemia显示文摘Children with severe aplastic anemia(SAA)face heterogeneous prognoses after immunosuppressive therapy(IST).There are few models that can predict the long-term outcomes of IST for these patients.The objective of this paper is to develop a more effective prediction model for SAA prognosis based on clinical electronic medical records from 203 children with newly diagnosed SAA.In the early stage,a novel model for long-term outcomes of SAA patients with IST was developed using machine-learning techniques.Among the indicators related to long-term efficacy,white blood cell count,lymphocyte count,absolute reticulocyte count,lymphocyte ratio in bone-marrow smears,C-reactive protein,and the level of IL-6,IL-8 and vitamin B12 in the early stage are strongly correlated with long-term efficacy(P<.05).Taken together,we analyzed the long-term outcomes of rabbit antithymocyte globulin and cyclosporine therapy for children with SAA through machine-learning techniques,which may shorten the observation period of therapeutic effects and reduce treatment costs and time. | Lixian Chang Mingchen Yan Jingliao Zhang Binghang Liu Li Zhang Ye Guo Jing Sun Yang Wan Meihui Yi Yang Lan Yuli Cai Yuanyuan Ren Haihui Zheng Aoli Zhang Zhenyu Li Jian Wang Yingrui Li Xiaofan Zhu | 2023 | Blood Science2023，5，3： | 0 |
| 6 | Structure and optical characterization of GaP-SiO_2 co-sputtered films显示文摘The films of GaP nanocrystals embedded in SiO2 matrix were prepared by radio frequency magnetron co-sputtering and subsequent anneal- ing technology. The structure and morphology of the films were investigated by scanning electron microscope, X-ray diffraction, and energy dispersive spectrum. Raman spectra results showed that the transverse optical phonon model (TO) and the longitudinal optical phonon model (LO) of GaP nanocrystals were both discovered to undergo red shift, broadening, and asymmetry. The red shift degree of the TO model was about 8.8 cm-1. The luminescence spectrum of the GaP/SiO2 film consisted of several emission peaks. 2.84-2.54 eV blue light emission was explained by the quantum confinement-luminescence centers model (QC-LCs). | CHAI Yuesheng YANG Meihui ZHANG Mingang SUN Gang | 2008 | Rare Metals2008，27，6： | 0 |
