| 1 | Aerodynamics and mechanisms of elementary morphing models for flapping wing in forward flight of bat显示文摘Large active wing deformation is a significant way to generate high aerodynamic forces required in bat's flapping flight. Besides the twisting, elementary morphing models of a bat wing are proposed, including wing-bending in the spanwise direction,wing-cambering in the chordwise direction, and wing area-changing. A plate of aspect ratio 3 is used to model a bat wing, and a three-dimensional unsteady panel method is used to predict the aerodynamic forces. It is found that the cambering model has great positive influence on the lift, followed by the area-changing model and then the bending model. Further study indicates that the vortex control is a main mechanism to produce high aerodynamic forces. The mechanisms of aerodynamic force enhancement are asymmetry of the cambered wing and amplification effects of wing area-changing and wing bending. Lift and thrust are generated mainly during downstroke, and they are almost negligible during upstroke by the integrated morphing model-wing. | Ziwu GUAN Yongliang YU | 2015 | Applied Mathematics and Mechanics(English Edition)2015，36，5： | 5 |
| 2 | Preparation of phosphorus-doped carbon nanospheres and their electrocatalytic performance for O_2 reduction显示文摘Phosphorus-doped carbon nanospheres without any metal residues were synthesized and characterized.The results revealed that the doping phosphorus atoms could significantly improve the electrocatalytic activity of graphitic carbon for the oxygen-reduction reaction(ORR) both in acidic and alkaline media,and the materials exhibited high electrocatalytic activity,long-term stability,and excellent tolerance to crossover effects especially in alkaline media.Quantum mechanics calculations with the density functional theory demonstrated that the changes in charge density and energetic characteristics of frontier orbitals for the P-doped graphene sheet could facilitate the ORR. | Ziwu Liu Feng Peng Hongjuan Wang Hao Yu Wenxu Zheng Xianyong Wei | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 4 |
| 3 | Learning from bat:Aerodynamics of actively morphing wing显示文摘Different from birds and insects,bats have complex wing-deformation capacity to generate high aerodynamic forces.In flight,the actively morphing of bat wing includes the twisting from wing root to wing tip,the cambering along the chordwise direction,the bending along the spanwise direction and the wing area-changing caused by the stretch and retraction of the wingspan.It was found that the high thrust and lift required in bat flight are dependent on the wing twisting and cambering respectively.Moreover,the integrated wing-morphing generates the aerodynamic lift and thrust mainly during the downstroke and almost negligible forces during the upstroke.The wing area-changing and bending can be used to amplify the positive forces in the downstroke duration and reduce the negative forces in the upstroke duration. | Yongliang Yu Ziwu Guan | 2015 | Theoretical & Applied Mechanics Letters2015，5，1： | 3 |
| 4 | The influence of the type of N dopping on the performance of bifunctional N-doped ordered mesoporous carbon electrocatalysts in oxygen reduction and evolution reaction显示文摘To develop more ideal bifunctional heteroatom-doped carbon electrocatalysts toward the oxygen reduction reaction(ORR) and oxygen evolution reaction(OER) for regenerative fuel cells and rechargeable metal–air batteries, herein, tobacco-derived N-containing ordered mesoporous carbon(N-OMC) electrocatalysts with different N species distributions are designed. Results indicate that the as-prepared N-OMC with more pyrrolic and pyridinic Ns exhibits much higher activities for the ORR and OER than N-OMC with more graphitic N in both acidic and alkaline media, suggesting that the increase of pyrrolic and pyridinic Ns favors the improvement of ORR and OER activities of the N-containing carbon catalysts, and showing a great potential for the designing of more effective, lower-cost ORR and OER bifunctional electrocatalysts for future regenerative fuel cells and rechargeable metal–air batteries. | Meng Li Ziwu Liu Fang Wang Jinjin Xuan | 2017 | Journal of Energy Chemistry2017，26，3： | 2 |
| 5 | Decoding Cortical Glial Cell Development显示文摘Mouse cortical radial glial cells(RGCs)are primary neural stem cells that give rise to cortical oligodendrocytes,astrocytes,and olfactory bulb(OB)GABAergic interneurons in late embryogenesis.There are fundamental gaps in understanding how these diverse cell subtypes are generated.Here,by combining single-cell RNA-Seq with intersectional lineage analyses,we show that beginning at around E16.5,neocortical RGCs start to generate ASCL1^(+)EGFR^(+)apical multipotent intermediate progenitors(MIPCs),which then differentiate into basal MIPCs that express ASCL1,EGFR,OLIG2,and MKI67.These basal MIPCs undergo several rounds of divisions to generate most of the cortical oligodendrocytes and astrocytes and a subpopulation of OB interneurons.Finally,single-cell ATAC-Seq supported our model for the genetic logic underlying the specification and differentiation of cortical glial cells and OB interneurons.Taken together,this work reveals the process of cortical radial glial cell lineage progression and the developmental origins of cortical astrocytes and oligodendrocytes. | Xiaosu Li Guoping Liu Lin Yang Zhenmeiyu Li Zhuangzhi Zhang Zhejun Xu Yuqun Cai Heng Du Zihao Su Ziwu Wang Yangyang Duan Haotian Chen Zicong Shang Yan You Qi Zhang Miao He Bin Chen Zhengang Yang | 2021 | Neuroscience Bulletin2021，37，4： | 2 |

| 15 | Anharmonic multi-phonon nonradiative transition: A n ab initio calculation approach显示文摘Nonradiative carrier recombinations at deep centers in semiconductors are of great importance for both fundamental physics and device engineering.In this article,we provide a revised analysis of Huang's original nonradiative multi-phonon(NMP)theory with ab initio calculations.First,we confirmed at the first-principles level that Huang's concise formula gives the same results as the matrix-based formula,and that Huang's high-temperature formula provides an analytical expression for the coupling constant in Marcus theory.Secondly,we correct for anharmonic effects by taking into account local phonon-mode variations for different charge states of a defect.The corrected capture rates for defects in GaN and SiC agree well with experiments. | Yao Xiao ZiWu Wang Lin Shi XiangWei Jiang ShuShen Li LinWang Wang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，7： | 0 |

| 17 | A Broad Range Triboelectric Stiffness Sensor for Variable Inclusions Recognition显示文摘With the development of artificial intelligence,stiffness sensors are extensively utilized in various fields,and their integration with robots for automated palpation has gained significant attention.This study presents a broad range self-powered stiffness sensor based on the triboelectric nanogenerator(Stiff-TENG)for variable inclusions in soft objects detection.The Stiff-TENG employs a stacked structure comprising an indium tin oxide film,an elastic sponge,a fluorinated ethylene propylene film with a conductive ink electrode,and two acrylic pieces with a shielding layer.Through the decoupling method,the Stiff-TENG achieves stiffness detection of objects within 1.0 s.The output performance and characteristics of the TENG for different stiffness objects under 4 mm displacement are analyzed.The Stiff-TENG is successfully used to detect the heterogeneous stiffness structures,enabling effective recognition of variable inclusions in soft object,reaching a recognition accuracy of 99.7%.Furthermore,its adaptability makes it well-suited for the detection of pathological conditions within the human body,as pathological tissues often exhibit changes in the stiffness of internal organs.This research highlights the innovative applications of TENG and thereby showcases its immense potential in healthcare applications such as palpation which assesses pathological conditions based on organ stiffness. | Ziyi Zhao Zhentan Quan Huaze Tang Qinghao Xu Hongfa Zhao Zihan Wang Ziwu Song Shoujie Li Ishara Dharmasena Changsheng Wu Wenbo Ding | 2023 | Nano-Micro Letters2023，15，12： | 0 |
