| 1 | Preparation and microstructure characterization of a nano-sized Ti^(4+)-doped AgSnO_2 electrical contact material显示文摘A Ti4+-doped nano-structured AgSnO2 material was prepared using sol-gel method and characterized by X-ray diffraction (XRD), transmis-sion electron microscopy (TEM), and scanning electron microscopy (SEM). The results show that Ti4+ cations are successfully doped into the crystal lattice of SnO2, and thus significantly improve the electrical conductivity of the sample. Furthermore, the coating of Ag on Ti4+-doped SnO2 nano-sized particles enhances the surface wettability and enables the resulting AgSnO2 material to have better mechanical properties. | ZHENG Ji LI Songlin DOU Fuqi LI Tonghui | 2009 | Rare Metals2009，28，1： | 24 |
| 2 | Lightweight Design of Automobile Drive Shaft Based on the Characteristics of Low Amplitude Load Strengthening显示文摘There are two kinds of internationally recognized approaches in terms of lightweight design.One is based on fatigue accumulated damage theory to achieve better reliability by optimal structural design;another is to use high performance lightweight materials.The former method takes very few considerations on the structural strengthening effects caused by the massive small loads in service.In order to ensure safety,the design is usually conservative,but the strength potential of the component is not fully exerted.In the latter method,cost is the biggest obstacle to lightweight materials in automotive applications.For the purpose of light weighting design on a fuel cell vehicle,the new design method is applied on drive shafts.The method is based on the low amplitude load strengthening characteristics of the material,and allows the stress,corresponding to test load,to enter into the strengthened range of the material.Under this condition,the light weighting design should assure that the reliability of the shaft is not impaired,even maximizes the strength potential of machine part in order to achieve the weight reduction and eventually to reduce the cost.At last,the feasibility of the design is verified by means of strength analysis and modal analysis based on the CAD model of light weighted shaft.The design applies to the load case of half shaft in independent axle,also provides technological reference for the structural lightweight design of vehicles and other machineries. | ZHENG Songlin XU Honghui FENG Jinzhi ZHENG Zuanxi WANG Youtao LU Leilei | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 16 |
| 3 | Research and Practice of Blending Teaching Based on “MOOC + SPOC + Flipped Classroom” for Software Engineering显示文摘Based on 'MOOC + SPOC + Flipped Classroom', a particular blending teaching pattern adapting to MOOC teaching is proposed to strengthen software engineering students' abilities to study themselves and practice innovatively. Firstly, the process of MOOC development in China is introduced. The distinguishing feature and effect of MOOC teaching are analyzed, followed by the comparison with traditional class. The online Plus offline blending teaching pattern is the combination of online self-study on MOOC before class, seminar study of flipped classroom in class and the summary after class. With the demonstration of a typical case, a progressive strategy is given to implement blending teaching. Finally, the blending teaching pattern is assessed from multiple perspectives, of which both advantages and disadvantages are dissected. Through primary exploration, introducing online study and flipped classroom, blending teaching plays a positive role in software engineering teaching, which means traditional teaching pattern is changed. Meanwhile, students' innovative consciousness and practical ability are inspired. Nevertheless, new problems arise, so that intensive practice and improvement are necessary. | Ce Zhang Dianhui Chu Songlin Gu Xiaofei Xu Jianan Jiang Zheng Wang Hua Zhang | 2018 | 计算机教育2018，，12： | 14 |

| 5 | A zinc finger protein, interacted with cyclophilin,affects root development via IAA pathway in rice显示文摘The plant hormone auxin plays a crucial role in lateral root development. To better understand the molecular mechanisms underlying lateral root formation,an auxin-responsive gene OsCYP2(Os02g0121300) was characterized from rice. Compared to the wild type,OsCYP2-RNAi(RNA interference) lines exhibited distinctive defects in lateral root development. Yeast two-hybrid and glutathione S-transferase pull-down results confirmed that OsCYP2 interacted with a C2HC-type zinc finger protein(OsZFP, Os01g0252900) which is located in the rice nucleus. T_2 OsZFP-RNAi lines had significantly fewer lateral roots than did wild-type plants, which suggests a role for OsCYP2 and OsZFP in regulating lateral root development.Quantitative real-time polymerase chain reaction showed that the expression of certain Aux/IAA(auxin/indole-3-acetic acid) genes was altered in OsCYP2-and Os ZFP-RNAi lines in response to IAA. These findings imply that OsCYP2 and OsZFP participate in IAA signal pathways controlling lateral root development. More importantly, OsIAA11 showed functional redundancy not only in OsCYP2-RNAi lines but also in Os ZFP-RNAi lines, which provides important clues for the elucidation of mechanisms controlling lateral root development in response to auxin. | Peng Cui Hongbo Liu Songlin Ruan Basharat Ali Rafaqat Ali Gill Huasheng Ma Zhifu Zheng Weijun Zhou | 2017 | Journal of Integrative Plant Biology2017，59，7： | 4 |
| 6 | Fatigue Life Prediction under Service Load Considering Strengthening Effect of Loads below Fatigue Limit显示文摘Lightweight design requires an accurate life prediction for structures and components under service loading histories. However, predicted life with the existing methods seems too conservative in some cases, leading to a heavy structure. Because these methods are established on the basis that load cycles would only cause fatigue damage, ignore the strengthening effect of loads. Based on Palmgren-Miner Rule(PMR), this paper introduces a new method for fatigue life prediction under service loadings by taking into account the strengthening effect of loads below the fatigue limit. In this method, the service loadings are classified into three categories: damaging load, strengthening load and none-effect load, and the process for fatigue life prediction is divided into two stages: stage I and stage II, according to the best strengthening number of cycles. During stage I, fatigue damage is calculated considering both the strengthening and damaging effect of load cycles. While during stage II, only the damaging effect is considered. To validate this method, fatigue lives of automobile half shaft and torsion beam rear axle are calculated based on the new method and traditional methods, such as PMR and Modified Miner Rule(MMR), and fatigue tests of the two components are conducted under service loading histories. The tests results show that the percentage errors of the predicted life with the new method to mean life of tests for the two components are –3.78% and –1.76% separately, much lesser than that with PMR and MMR. By considering the strengthening effect of loads below the fatigue limit, the new method can significantly improve the accuracy for fatigue life prediction. Thus lightweight design can be fully realized in the design stage. | ZHAO Lihui ZHENG Songlin FENG Jinzhi | 2014 | Chinese Journal of Mechanical Engineering2014，27，6： | 4 |
| 7 | Colour compound lenses for a portable fluorescence microscope显示文摘In this article,we demonstrated a handheld smartphone fluorescence microscope(HSFM)that integrates dualfunctional polymer lenses with a smartphone.The HSFM consists of a smartphone,a field-portable illumination source,and a dual-functional polymer lens that performs both optical imaging and filtering.Therefore,compared with the existing smartphone fluorescence microscope,the HSFM does not need any additional optical filters.Although fluorescence imaging has traditionally played an indispensable role in biomedical and clinical applications due to its high specificity and sensitivity for detecting cells,proteins,DNAs/RNAs,etc.,the bulky elements of conventional fluorescence microscopes make them inconvenient for use in point-of-care diagnosis.The HSFM demonstrated in this article solves this problem by providing a multifunctional,miniature,small-form-factor fluorescence module.This multifunctional fluorescence module can be seamlessly attached to any smartphone camera for both bright-field and fluorescence imaging at cellular-scale resolutions without the use of additional bulky lenses/filters;in fact,the HSFM achieves magnification and light filtration using a single lens.Cell and tissue observation,cell counting,plasmid transfection evaluation,and superoxide production analysis were performed using this device.Notably,this lens system has the unique capability of functioning with numerous smartphones,irrespective of the smartphone model and the camera technology housed within each device.As such,this HSFM has the potential to pave the way for realtime point-of-care diagnosis and opens up countless possibilities for personalized medicine. | Bo Dai Ziao Jiao Lulu Zheng Hunter Bachman Yongfeng Fu Xinjun Wan Yule Zhang Yu Huang Xiaodian Han Chenglong Zhao Tony Jun Huang Songlin Zhuang Dawei Zhang | 2019 | Light(Science & Applications)2019，8，1： | 3 |
| 8 | Near‑Instantaneously Self‑Healing Coating toward Stable and Durable Electromagnetic Interference Shielding显示文摘Durable electromagnetic interference(EMI)shielding is highly desired,as electromagnetic pollution is a great concern for electronics’stable performance and human health.Although a superhydrophobic surface can extend the service lifespan of EMI shielding materials,degradation of its protection capability and insufficient self-healing are troublesome issues due to unavoidable physical/chemical damages under long-term application conditions.Here,we report,for the first time,an instantaneously self-healing approach via microwave heating to achieve durable shielding performance.First,a hydrophobic 1H,1H,2H,2H-perfluorooctyltriethoxysilane(POTS)layer was coated on a polypyrrole(PPy)-modified fabric(PPy@POTS),enabling protection against the invasion of water,salt solution,and corrosive acidic and basic solutions.Moreover,after being damaged,the POTS layer can,for the first time,be instantaneously self-healed via microwave heating for a very short time,i.e.,4 s,benefiting from the intense thermal energy generated by PPy under electromagnetic wave radiation.This self-healing ability is also repeatable even after intentionally severe plasma etching,which highlights the great potential to achieve robust and durable EMI shielding applications.Significantly,this approach can be extended to other EMI shielding materials where heat is a triggering stimulus for healing thin protection layers.We envision that this work could provide insights into fabricating EMI shielding materials with durable performance for portable and wearable devices,as well as for human health care. | Lihua Zou Chuntao Lan Songlin Zhang Xianhong Zheng Zhenzhen Xu Changlong Li Li Yang Fangtao Ruan Swee Ching Tan | 2021 | Nano-Micro Letters2021，13，11： | 3 |
| 9 | Suspended penetration wetting state of droplets on microstructured surfaces显示文摘When a water droplet on a micropillar-structured hydrophobic surface is submitted to gradually increased pressure, the CassieBaxter wetting state transforms into the Wenzel wetting state once the pressure exceeds a critical value. It has been assumed that the reverse transition(Wenzel-to-Cassie-Baxter wetting state) cannot happen spontaneously after the pressure has been removed.In this paper, we report a new wetting-state transition. When external pressure is exerted on a droplet in the Cassie-Baxter wetting state on textured surfaces with high micropillars to trigger the breakdown of this wetting state, the droplet penetrates the micropillars but does not touch the base of the surface to trigger the occurrence of the Wenzel wetting state. We have named this state the suspended penetration wetting state. Spontaneous recovery from the suspended penetration wetting state to the initial Cassie-Baxter wetting state is achieved when the pressure is removed. Based on the experimental results, we built models to establish the penetration depth that the suspended penetration wetting state could achieve and to understand the energy barrier that influences the equilibrium position of the liquid surface. These results deepen our understanding of wetting states on rough surfaces subjected to external disturbances and shed new light on the design of superhydrophobic materials with a robust wetting stability. | Jing Lou SongLin Shi Chen Ma CunJing Lv QuanShui Zheng | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，4： | 2 |

| 18 | Sweat-Driven Silk-yarn Switches Enabled by Highly Aligned Gaps for Air-conditioning Textiles显示文摘Smart textiles are attracting great interest.Particularly,air-conditioning textiles are highly desired for their merits in energy conservation and personal temperature/humidity management.Currently,air-conditioning textiles can be fabricated by two strategies.One uses infrared-radiation-adaptive materials,and the other uses moisture-responsive actuators that can regulate temperature and humidity simultaneously.Here,the fabrication of a silk-yarn switch comprising electrospun highly aligned nanofibers is reported and its application in air-conditioning textiles is demonstrated.Silk yarn rotates in contact with liquid,and can be recovered by drying.The different responses and wetting behaviors of the switch to H_(2)O and C_(2)H_(6)O is investigated.It is argued that alignment and surface hydrophilicity of nanofibers play important roles in this term.To elaborate,actuating trait is mainly controlled by reduction of the surface free energy of aligned silk nanofibers,during the wetting process.As proof of concept,the application of the sweat-driven silk-yarn switch in regulating the temperature/humidity of the human body is demonstrated in this work.Considering the large production,versatile processibility,and good biocompatibility,silk actuator may have practical applications in designing smart switches(or valves)for intelligent textiles,artificial muscles,and other application scenarios. | Zhe Yin Songlin Shi Xiaoping Liang Mingchao Zhang Quanshui Zheng Yingying Zhang | 2019 | Advanced Fiber Materials2019，1，3： | 1 |
