| 1 | Molecular behaviors in thin film lubrication——Part two: Direct observation of the molecular orientation near the solid surface显示文摘Over the past twenty years, thin film lubrication(TFL) theory has been used to characterize the molecular behaviors in lubrication films thinner than 100 nm, effectively bridging the gap between elastohydrodynamic lubrication and boundary lubrication. Unfortunately, to date, the TFL molecular model proposed in 1996 has not been directly proven by experimental detection. Herein, a method based on surface-enhanced Raman spectroscopy was developed to show both the packing and orienting of liquid molecules in the TFL regime. By trapping liquid crystal molecules between a structured silver surface and a glass surface, molecular ordering states dominated by shear effect and surface effect were successfully distinguished. A nanosandwich structure consisting of an adsorbed layer, an ordered-molecule layer, and a fluid layer was demonstrated. Molecule imaging in TFL was achieved. Our results illustrate the molecular behaviors and lubrication mechanism in nanoconfined films and facilitate the lubrication design of nanoelectromechanical and microelectromechanical systems. | Ming GAO Haoyu LI Liran MA Yuan GAO Linwei MA Jianbin LUO | 2019 | Friction2019，7，5： | 5 |
| 2 | Cephalopods-inspired Repairable MWCNTs/PDMS Conductive Elastomers for Sensitive Strain Sensor显示文摘Flexible electronic devices based on reversible bonds for self-curing capabilities arouses extensive interest.However,most of the composite conductive elastomers have the problems of poor mechanical properties and slow recovery of mechanical properties during multiple stretching,which hinder their stability in continuous operation.In this study,hyperbranched-MWCNTs/hyperbranched-PDMS self-healable conductive elastomers inspired by cephalopods were successfully developed.The prepared conductive elastomer exhibited good self-healing ability(91%)at room temperature excited by multiple reversible interactions.The prepared elastomer showed outstanding mechanical properties and anti-fatigue ability,so that it can cope with more arduous tasks.Moreover,the elastomer was sensitive to the change of stress states and can be used as a stable strain sensor.Therefore,the self-repairing conductive elastomer has potential practicability in the fields of human-computer interaction,motion monitoring,soft robot and so on. | Kaiming Zhang Zhe Wang Yuetao Liu Haoyu Zhao Chuanhui Gao Yumin Wu | 2022 | Chinese Journal of Polymer Science2022，40，4： | 2 |
| 3 | Finite-element analysis for surface discharge on polyimide insulation in air at atmospheric pressure under pulsed electrical stress显示文摘A surface discharge non-equilibrium plasma model of air–polyimide under pulsed electrical stress is established, byconsidering the reaction of charged particles on the dielectric surface and the secondary electron emission caused by thecondition that high-energy particles bombard the material surface. The model defines the chemical reaction of air discharge byusing simplified set of reactions, which greatly reduces the complexity of the model. To avoid the negative value of particledensity in the process of solution, the logarithmic finite-element method is used to solve the model established, so as toimplement the dynamic simulation of the surface discharge process. Also, the temporal and spatial evolution of themicroparameters such as charge and electric field distribution during discharge are obtained, and the reliability of the model isverified by experiments in terms of discharge development pattern and surface charge accumulation. By comparing thedevelopment process of surface discharge under single pulse and repetitive pulses, it can be seen that surface dischargedevelops from needle electrode to ground electrode under both repetitive pulses and single pulse stress, but the relationshipbetween the discharge propagation time under repetitive pulses and pulse repetition rate is a ‘u’ curve, and the inflection pointmoves to higher repetition rate region with the increase of voltage. | Guojing Dong Qingmin Li Tao Liu Haoyu Gao Minhao Zhang | 2020 | High Voltage2020，5，2： | 2 |

| 5 | Is oral microbiome of children able to maintain resistance and functional stability in response to short-term interference of ingesta?显示文摘Dear Editor,A series of studies had focused on the ecological stability of human microbiome(Lozupone et al.,2012;Faith et al.,2013;Moya and Ferrer,2016).Despite the continuous perturbation and the highly personalized composition within the human microbiome(Human Microbiome Project,2012),healthy adults stably maintain their microbial communities in terms of space and time(Faith et al.,2013;Moya and Ferrer,2016;Oh et al.,2016).This stability is proved to be critical for the well-being of human body(Lozupone et al.,2012).On the contrary,major shifts in microbial community composition are often related to diseases(Lynch and Pedersen,2016). | Fangqiao Wei Xiangyu Sun Yufeng Gao Haoyu Dou Yang Liu Lili Su Haofei Luo Ce Zhu Qian Zhang Peiyuan Tong Wen Ren Zhe Xun Ruochun Guo Yuanlin Guan Shenghui Li Yijun Qi Junjie Qin Feng Chen Shuguo Zheng | 2021 | Protein & Cell2021，12，6： | 1 |

| 9 | Integrated in silico formulation design of selfemulsifying drug delivery systems显示文摘The drug formulation design of self-emulsifying drug delivery systems(SEDDS)often requires numerous experiments,which are time-and money-consuming.This research aimed to rationally design the SEDDS formulation by the integrated computational and experimental approaches.4495 SEDDS formulation datasets were collected to predict the pseudo-ternary phase diagram by the machine learning methods.Random forest(RF)showed the best prediction performance with 91.3% for accuracy,92.0% for sensitivity and 90.7% for specificity in 5-fold cross-validation.The pseudo-ternary phase diagrams of meloxicam SEDDS were experimentally developed to validate the RF prediction model and achieved an excellent prediction accuracy(89.51%).The central composite design(CCD)was used to screen the best ratio of oil-surfactant-cosurfactant.Finally,molecular dynamic(MD)simulation was used to investigate the molecular interaction between excipients and drugs,which revealed the diffusion behavior in water and the role of cosurfactants.In conclusion,this research combined machine learning,central composite design,molecular modeling and experimental approaches for rational SEDDS formulation design.The integrated computer methodology can decrease traditional drug formulation design works and bring new ideas for future drug formulation design. | Haoshi Gao Haoyue Jia Jie Dong Xinggang Yang Haifeng Li Defang Ouyang | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 1 |

| 12 | Smart palm-size optofluidic hematology analyzer for automated imaging-based leukocyte concentration detection显示文摘A critical function of flow cytometry is to count the concentration of blood cells,which helps in the diagnosis of certain diseases.However,the bulky nature of commercial flow cytometers makes such tests only available in hospitals or laboratories,hindering the spread of point-of-care testing(POCT),especially in underdeveloped areas.Here,we propose a smart Palm-size Optofluidic Hematology Analyzer based on a miniature fluorescence microscope and a microfluidic platform to lighten the device to improve its portability.This gadget has a dimension of 35×30×80 mm and a mass of 39 g,less than 5%of the weight of commercially available flow cytometers.Additionally,automatic leukocyte concentration detection has been realized through the integration of image processing and leukocyte counting algorithms.We compared the leukocyte concentration measurement between our approach and a hemocytometer using the Passing-Bablok analysis and achieved a correlation coefficient of 0.979.Through Bland-Altman analysis,we obtained the relationship between their differences and mean measurement values and established 95%limits of agreement,ranging from−0.93×10^(3)to 0.94×10^(3)cells/μL.We anticipate that this device can be used widely for monitoring and treating diseases such as HIV and tumors beyond hospitals. | Deer Su Xiangyu Li Weida Gao Qiuhua Wei Haoyu Li Changliang Guo Weisong Zhao | 2023 | Opto-Electronic Science2023，2，12： | 1 |
| 13 | Teaching Reform for HarmonyOS Mobile Application Development显示文摘In recent years,the IT industry in China has developed rapidly and made remarkable achievements.However,there is still a big gap between China and foreign countries in the core fields of information technology,such as system hardware and software platform.Currently,foreign countries have gradually raised the restrictions of information technology in China,and even added many domestic enterprises to the restricted list,which has rung the alarm to the information security of the country.Therefore,in order to break through the foreign technology blockade and find a unique way in independent software and hardware platform,it is urgent to carry out the curriculum construction and talent training mechanism on core software and hardware platform.HarmonyOS is a“future-oriented”distributed operating system developed by Huawei.It proposes a distributed concept based on the same system capability and adapts to a variety of terminal forms,and supports a variety of terminal devices such as mobile phones,watches and smart screens.Our course on HarmonyOS aims to increase the theoretical knowledge of the core independent software and hardware platform.In the course,we exploit our teaching reform experience in the course of“Mobile Application Development”,and investigate the teaching mechanism of HarmonyOS to contribute to the rapid development of information technology and ecological construction in China. | Ruipeng Gao Weiwei Xing Haoyue Zhao Dan Tao | 2021 | 计算机教育2021，，12： | 1 |
| 14 | Identification of biomarkers associated with the feed efficiency by metabolomics profiling:results from the broiler lines divergent for high or low abdominal fat content显示文摘Background:Improving feed efficiency(FE)is one of the main objectives in broiler breeding.It is difficult to directly measure FE traits,and breeders hence have been trying to identify biomarkers for the indirect selection and improvement of FE traits.Metabolome is the'bridge'between genome and phenome.The metabolites may potentially account for more of the phenotypic variation and can suitably serve as biomarkers for selecting FE traits.This study aimed to identify plasma metabolite markers for selecting high-FE broilers.A total of 441 birds from Northeast Agricultural University broiler lines divergently selected for abdominal fat content were used to analyze plasma metabolome and estimate the genetic parameters of differentially expressed metabolites.Results:The results identified 124 differentially expressed plasma metabolites(P<0.05)between the lean line(highFE birds)and the fat line(low-FE birds).Among these differentially expressed plasma metabolites,44 were found to have higher positive or negative genetic correlations with FE traits(|r_g|≥0.30).Of these 44 metabolites,14 were found to display moderate to high heritability estimates(h~2≥0.20).However,among the 14 metabolites,4 metabolites whose physiological functions have not been reported were excluded.Ultimately,10 metabolites were suggested to serve as the potential biomarkers for breeding the high-FE broilers.Based on the physiological functions of these metabolites,reducing inflammatory and improving immunity were proposed to improve FE and increase production efficiency.Conclusions:According to the pipeline for the selection of the metabolite markers established in this study,it was suggested that 10 metabolites including 7-ketocholesterol,dimethyl sulfone,epsilon-(gamma-glutamyl)-lysine,gamma-glutamyltyrosine,2-oxoadipic acid,L-homoarginine,testosterone,adenosine 5'-monophosphate,adrenic acid,and calcitriol could be used as the potential biomarkers for breeding the'food-saving broilers'. | Zhiyong Su Xue Bai Haoyu Wang Shouzhi Wang Chong Chen Fan Xiao Huaishun Guo Haihe Gao Li Leng Hui Li | 2023 | Journal of Animal Science and Biotechnology2023，14，1： | 0 |

| 16 | Realizing the Long Lifespan of Molybdenum Trioxide in Aqueous Aluminum Ion Batteries Through Potential Regulation显示文摘MoO_(3) is one of the most promising anode materials for aqueous aluminum batteries due to its high theoretical capacity and suitable aluminum insertion/de-insertion potential.However,the inferior cycling stability limits its further application,and the failure mechanism is still unclear.In this article,we provide a straightforward potential regulation technique to manage phase evolution during the charge/discharge process,which ultimately results in a markedly enhanced MoO_(3) electrode cycling stability.The failure mechanism study reveals that the excessive oxidation of the electrode during charge/discharge generates the H_(0.34)MoO_(3) phase,which has high solubility and is the primary cause of MoO_(3) deactivation.Although the dissolved Mo species will be deposited onto the electrode sheet again,the deposition is not electrochemically active and cannot contribute to the capacitance.Controlling the cutoff potential prevented the production of H_(0.34)MoO_(3),resulting in excellent cycling performance(80.1% capacity retention after 4000 cycles).The as-assembled α-MoO_(3)//MnO_(2) full battery exhibits high discharge plateaus(1.4 and 0.9 V),large specific capacity(200 mAhg^(-1) at 2 Ag^(-1)),and ultra-high coulombic efficiency(99%).The research presented here may contribute to the development of highly stable electrode materials for aqueous batteries. | Haodong Fan Xuejin Li Jie Zhou Xiaoning Wang Xiuli Gao Haoyu Hu Li Zhou Tonghui Cai Yongpeng Cui Pengyun Liu Qingzhong Xue Zifeng Yan Wei Xing | 2023 | Renewables2023，1，4： | 0 |

| 18 | Eco-geographical Regionalization of China:An Approach Using the Rough Set Method显示文摘Eco-geographical regionalization involves dividing land into regions by considering both intra-regional consistency and interregional disparity and is based on the pattern of differentiation of eco-geographical elements.Owing to the complexity of the land surface,and the limitation of data and appropriate methods,regions in China have hitherto been mapped manually,meaning that the process of mapping was non-repeatable.To make the regionalization technique repeatable,this study aimed to extract and quantify the expert knowledge of regionalization using an automated method.The rough set method was adopted to extract rules of regionalization based on the existing eco-geographical regionalization map of China,as well as its corresponding meteorological and geological datasets.Then,the rules for regionalization were obtained hierarchically for each natural domain,each temperature zone,and each humidity region.Owing to differences in zonal differentiation,the rule extraction sequence for the eastern monsoon zone and Tibetan Alpine zone was temperature zone first followed by humidity region,with the reverse order being applied for the northwest arid/semi-arid zone.Results show that the extracted indicators were similar to those of the existing(expert-produced)regionalization scheme but more comprehensive.The primary indicator for defining temperature zones was the≥10℃ growing season,and the secondary indicators were the January and July mean temperatures.The primary and secondary indicators for identifying humid regions were aridity index and precipitation,respectively.Eco-geographical regions were mapped over China using these rules and the gridded indicators.Both the temperature zones and humidity regions mapped by the rules show≥85%consistency with the existing regionalization,which is higher than values for mapping by the commonly used simplified method that uses the classification of one indicator.This study demonstrates that the proposed rough set method can establish eco-geographical regionalization that is quantitative and repeatable and able to dynamically updated. | DENG Haoyu WU Shaohong YIN Yunhe GAO Jiangbo ZHAO Dongsheng | 2022 | Chinese Geographical Science2022，32，1： | 0 |
| 19 | Design and Fabrication of Reflective Phase Shifter for Two-Dimensional Terahertz Beam-Scanning Reflectarray显示文摘A reflective phase shifter is proposed to realize the two-dimensional beam-scanning reflectarray.The reflectarray is composed of double-dipole resonant elements in which the phase shift is implemented by applying a driving voltage to the liquid crystal(LC). A 30 ×30 phase shifter sample is fabricated on a quartz substrate with a 480 μm thickness and a 4 cm × 4 cm area.According to the experimental results, 0 to 360° phase shift can be achieved within the bandwidth of 5 GHz. In order to accomplish two-dimensional beam-scanning and reduce the negative impact of driving lines on the reflectarray, a new LC driving method is developed. To verify the accuracy of the proposed approach, three samples of different driving line numbers are designed using the above-mentioned phase shifter, which all have achieved a0-360° phase shift in the bandwidth of 4 GHz. Considering the influence of LC anisotropy and inhomogeneity, an improved calculation result is obtained and compared with experimental data. | YANG Jun YIN Mingjun GAO Haoyu YIN Zhiping YE Yang DENG Guangsheng LU Hongbo | 2022 | Chinese Journal of Electronics2022，31，3： | 0 |
