| 1 | Machine learning in materials science显示文摘Traditional methods of discovering new materials,such as the empirical trial and error method and the density functional theory(DFT)-based method,are unable to keep pace with the development of materials science today due to their long development cycles,low efficiency,and high costs.Accordingly,due to its low computational cost and short development cycle,machine learning is coupled with powerful data processing and high prediction performance and is being widely used in material detection,material analysis,and material design.In this article,we discuss the basic operational procedures in analyzing material properties via machine learning,summarize recent applications of machine learning algorithms to several mature fields in materials science,and discuss the improvements that are required for wide-ranging application. | Jing Wei Xuan Chu Xiang-Yu Sun Kun Xu Hui-Xiong Deng Jigen Chen Zhongming Wei Ming Lei | 2019 | InfoMat2019，1，3： | 9 |
| 2 | Effects of external stress on biodegradable orthopedic materials: A review显示文摘Biodegradable orthopedic materials(BOMs)are used in rehabilitation and reconstruction of fractured tissues.The response of BOMs to the combined action of physiological stress and corrosion is an important issue in vivo since stress-assisted degradation and cracking are common.Although the degradation behavior and kinetics of BOMs have been investigated under static conditions,stress effects can be very serious and even fatal in the dynamic physiological environment.Since stress is unavoidable in biomedical applications of BOMs,recent work has focused on the evaluation and prediction of the properties of BOMs under stress in corrosive media.This article reviews recent progress in this important area focusing on biodegradable metals,polymers,and ceramics. | Xuan Li Chenglin Chu Paul K.Chu | 2016 | Bioactive Materials2016，1，1： | 5 |
| 3 | Evaluation of humic acid removal by a flat submerged membrane photoreactor显示文摘A flat submerged membrane combined with a TiO 2 /UV photocatalytic reactor (FSMPR) was employed in batch mode to remove humic acid (HA). HA removal efficiency was characterized by UV 254 absorbance, UV-vis spectra, dissolved organic carbon (DOC) concentration, specific UV absorbance (SUVA), and trihalomethane formation potential (THMFP). The FSMPR process was effective in removing more than 86% of DOC and nearly 100% of UV 254 absorbance, while the THMFPs of samples were reduced to < 19 μ g/L after 150 min of treatment. In addition, changes in transmembrane pressure (TMP) with and without UV were evaluated; TiO 2 /UV was effective at controlling membrane fouling by HA. Analysis of the molecular weight (MW) distributions and three-dimensional excitation-emission matrix (EEM) fluorescence spectra of HAs revealed that the effectiveness in membrane fouling control is a result of changes in HA molecular characteristics. The TiO 2 /UV photocatalytic reactor caused the degradation of high MW, hydrophobic humic-like molecules to low MW, hydrophilic protein-like molecules, although this fraction was not completely removed during 150 min of treatment and was less responsible for membrane fouling. | WEI Yong CHU HuaQiang DONG BingZhi LI Xuan | 2011 | Chinese Science Bulletin2011，56，32： | 3 |
| 4 | Implementing the communication for development strategy to improve knowledge and coverage of measles vaccination in western Chinese immunization programs:a before-and-after evaluation显示文摘Background:Communication for Development(C4D)is a strategy promoted by the United Nations Children’s Fund to foster positive and measurable changes at the individual,family,community,social,and policy levels of society.In western China,C4D activities have previously been conducted as part of province-level immunization programs.In this study,we evaluated the association of C4D with changes in parental knowledge of immunization services,measles disease,and measles vaccine,and changes in their children’s measles vaccine coverage.Methods:From April 2013 to April 2014,C4D activities were implemented as part of provincial immunization programs in the Inner Mongolia,Guangxi,Chongqing,Guizhou,Tibet,Shaanxi,Gansu,Ningxia,and Qinghai provinces.We used a before-and-after study design and employed face-to-face interviews to assess changes in parental knowledge and vaccination coverage.Results:We surveyed 2107 households at baseline and 2070 households after 1 year of C4D activities.Following C4D,95%of caregivers were aware of the vaccination record check requirement for entry into kindergarten and primary school;80%of caregivers were aware that migrant children were eligible for free vaccination;more than 70%of caregivers knew that measles is a respiratory infectious disease;and 90%of caregivers knew the symptoms of measles.Caregivers’willingness to take their children to the clinic for vaccination increased from 51.3%at baseline to 67.4%in the post-C4D survey.Coverage of one-dose measles-containing vaccine(MCV)increased from 83.8%at baseline to 90.1%after C4D.One-dose MCV coverage was greater than 95%in the Guangxi,Shaanxi,and Gansu provinces.Two-dose MCV coverage increased from 68.5 to 77.6%.House-to-house communication was the most popular C4D activity among caregivers(91.6%favoring),followed by posters and educational talks(64.8 and 49.9%favoring).Conclusions:C4D is associated with increased caregiver knowledge about measles,increased willingness to seek immunization services for their children,and increased measles vaccination coverage.Tailored communication strategies based on insights gained from these analyses may be able to increase vaccination coverage in hard-to-reach areas.C4D should be considered for larger scale implementation in China. | Ming Lu Yao-Zhu Chu Wen-Zhou Yu Robert Scherpbier Yu-Qing Zhou Xu Zhu Qi-Ru Su Meng-Juan Duan Xuan Zhang Fu-Qiang Cui Hua-Qing Wang Yi-Biao Zhou Qing-Wu Jiang | 2017 | Infectious Diseases of Poverty2017，6，1： | 3 |

| 6 | Nischarin-siRNA delivered by polyethyleniminealginate nanoparticles accelerates motor function recovery after spinal cord injury显示文摘A previous study by our group found that inhibition of nischarin promotes neurite outgrowth and neuronal regeneration in Neuro-2 a cells and primary cortical neurons.In recent years,more and more studies have shown that nanomaterials have good prospects in treatment of spinal cord injury.We proposed that small interfering RNA targeting nischarin(Nis-si RNA) delivered by polyethyleneimine-alginate(PEIALG) nanoparticles promoted motor function recovery in rats with spinal cord injury.Direct microinjection of 5 μL PEI-ALG/Nis-si RNA into the spinal cord lesion area of spinal cord injury rats was performed.From day 7 after surgery,Basso,Beattie and Bresnahan score was significantly higher in rats from the PEI-ALG/Nis-si RNA group compared with the spinal cord injury group and PEI-ALG/Control-si RNA group.On day 21 after injection,hematoxylin-eosin staining showed that the necrotic area was reduced in the PEI-ALG/Nis-si RNA group.Immunohistochemistry and western blot assay results confirmed successful inhibition of nischarin expression and increased protein expression of growth-associated protein-43 in the PEI-ALG/Nis-si RNA group.These findings suggest that a complex of PEI-ALG nanoparticles and Nis-si RNA effectively suppresses nischarin expression,induces expression of growth-associated protein-43,and accelerates motor function recovery after spinal cord injury. | Yue-min Ding Yu-ying Li Chu Wang Hao Huang Chen-chen Zheng Shao-han Huang Yang Xuan Xiao-yi Sun Xiong Zhang | 2017 | Neural Regeneration Research2017，12，10： | 2 |

| 9 | Study on Shear Strength Characteristics of Columnar Jointed Basalt Based on in-situ Direct Shear Test at Baihetan Hydropower Station显示文摘Columnar jointed basalt(CJB) widely distributes in the dam site of the Baihetan Hydropower Station.The columnar joint structure and fracture development of CJB have significant influence on the mechanical properties of rock mass,and the mechanical properties of CJB are of great significance to the Baihetan Hydropower Project.Therefore,in-situ direct shear tests were carried out on ten test adit at different locations in the dam site area to study the shear behavior of CJB.In this study,21 sets of in-situ direct shear tests were conducted for rock types of type Ⅱ_(2),type Ⅲ_(1)and type Ⅲ_(2),with horizontal and vertical shear planes and two different specimen sizes of CJB.Shear strength parameters of CJB were obtained by linear fitting of in-situ direct shear test results based on the Mohr-Coulomb strength criterion.The results indicate that the shear strength parameters of CJB with horizontal shear plane increase as the increase of rock type grade.The shear strength parameters of CJB show obvious anisotropy and the friction coefficient of the horizontal shear plane is greater than the vertical shear plane.The friction coefficient in the horizontal direction of the shear plane is 1.27 times that in the vertical direction of the shear plane.With the increase of rock type grade,the difference of friction coefficient becomes larger.However,the cohesion changes little whether the shear plane is horizontal or vertical.In addition,the size effect of CJB in this area is significant.The shear strength parameters of large size(100 cm × 100 cm) specimens are lower than those of regular size(50 cm × 50 cm) specimens.The reduction of cohesion is greater than that of the friction coefficient.For rock type Ⅲ_(2),the cohesion of large-size specimens is 0.637 of the regular-size specimens.The reduction percentage of the friction coefficient for type Ⅲ_(2)is 1.66 times that of type Ⅲ_(1).The reduction percentage of the cohesion for type Ⅲ_(2)is 1.27 times that of type Ⅲ_(1).The size effect decreases with the increase of rock type grade.The research results of this study can provide an important basis for the selection of rock mechanics parameters in the dam site area of Baihetan Hydropower Station and the stability analysis of the dam foundation and rocky slopes. | Peng Xia Xinli Hu Shuangshuang Wu Chunye Ying Chu Xu Xuan Wang Hao Chen | 2023 | Journal of Earth Science2023，34，4： | 1 |

| 13 | Impact behaviors of poly-lactic acid based biocomposite reinforced with unidirectional high-strength magnesium alloy wires显示文摘A novel poly-lactic acid(PLA) based biocomposite reinforced with unidirectional high-strength magnesium alloy(Mg-alloy) wires for bone fracture fixation was fabricated by hot-compressing process. The macroscopical and microscopical impact behaviors of the biocomposite were investigated using impact experiments and finite element method(FEM), respectively. The results indicated that the biocomposite had favorable impact properties due to the plastic deformation behavior of Mg-alloy wires during impact process. While the content of Mg-alloy wires reached20 vol%, the impact strength of the composite could achieve 93.4 k J/m2, which is approximate 16 times larger than that of pure PLA fabricated by the same process. According to FEM simulation results, the complete destruction life of the composites during impact process increased with increasing volume fraction of Mg-alloy wires, indicating a high impact-bearing ability of the composite for bone fracture fixation.Simultaneously, the energy absorbed by Mg-alloy wires in the composites had a corresponding increase. In addition, it denoted that the impact properties of the composites are sensitive to the initial properties of the matrix material. | Xuan Li Chao Guo Xiaokai Liu Lei Liu Jing Bai Feng Xue Pinghua Lin Chenglin Chu | 2014 | Progress in Natural Science:Materials International2014，24，5： | 1 |

| 20 | The influence of alternating cyclic dynamic loads with different low frequencies on the bio-corrosion behaviors of AZ31B magnesium alloy in vitro显示文摘The real physiological environment of human body is complicated with different degrees and forms of dynamic loads applied to implanted medical devices due to the daily activities of the patients,which would have impacts on the degradation behaviors of magnesium alloy implants.In this work,the bio-corrosion behaviors of AZ31B magnesium alloy under alternating cyclic dynamic loads with different low frequencies(0.1-2.5 Hz)were specially investigated.It was found that the bio-degradation performances under external dynamic stressed conditions were much severer than those under unstressed conditions and static loads.The corrosion rates were generally accelerated as the rise of cyclic frequency.Hereby a numerical model for the degradation process of Mg alloy was established.The corrosion current density icorr of Mg alloy and the applied loading frequency f matches a linear relationship of ln icorr∝f,which is the result of interactions between the cyclic alternating load and corrosive environment.This work could provide a theoretical reference and an experimental basis for further researches on the biodegradation behaviors of biomedical materials under dynamic conditions. | Linyuan Han Zhenwei Zhang Jianwei Dai Xuan Li Jing Bai Zhihai Huang Chao Guo Feng Xue Chenglin Chu | 2022 | Bioactive Materials2022，7，1： | 0 |
