| 1 | The global oxygen budget and its future projection显示文摘Atmospheric oxygen (O_2 ) is the most crucial element on earth for the aerobic organisms that depend on it to release energy from carbon-based macromolecules. This is the first study to systematically analyze the global O_2 budget and its changes over the past 100 years. It is found that anthropogenic fossil fuel combustion is the largest contributor to the current O_2 deficit, which consumed 2.0 Gt/a in 1900 and has increased to 38.2 Gt/a by 2015. Under the Representative Concentration Pathways (RCPs) RCP8.5 scenario, approximately 100Gt (gigatonnes) of O_2 would be removed from the atmosphere per year until 2100,and the O_2 concentration will decrease from its current level of 20.946%to 20.825%. Human activities have caused irreversible decline of atmospheric O_2 . It is time to take actions to promote O_2 production and reduce O_2 consumption. | Jianping Huang Jiping Huang Xiaoyue Liu Changyu Li Lei Ding Haipeng Yu | 2018 | Science Bulletin2018,63,18: | 14 |
| 2 | Adjusting energy level alignment between HTL and CsPbI_(2)Br to improve solar cell efficiency显示文摘Lead halide perovskites are at the forefront of optoelectronic materials due to their high absorption coefficient,tunable bandgap,long carrier diffusion length,and small exciton binding energy[1−3],yielding high-performance optoelectronic devices. | Zihan Zhang Jia Li Zhimin Fang Haipeng Xie Yongbo Yuan Chuantian Zuo Liming Ding Bin Yang | 2021 | Journal of Semiconductors2021,42,3: | 3 |
| 3 | Muscle-fiber array inspired,multiple-mode,pneumatic artificial muscles through planar design and one-step rolling fabrication显示文摘Advances in development of artificial muscles have enabled creation of soft robots with biological dexterity and self-adaption in unstructured environments;however,production of scalable artificial muscles with multiple-mode actuations remains elusive.Inspired by muscle-fiber arrays in muscular hydrostats,we present a class of versatile artificial muscles called MAIPAMs(muscle-fiber array inspired pneumatic artificial muscles),capable of multiple-mode actuations(such as parallel elongation-bending-spiraling actuations,10 parallel bending actuations and cascaded elongation-bending-spiraling actuations).Our MAIPAMs consist of active 3D elastomer-balloon arrays reinforced by a passive elastomer membrane,achieved through a planar design and one-step rolling fabrication approach.We introduce prototypical designs for the MAIPAMs and demonstrate their muscle-mimic structures and versatility,as well as their scalable ability to integrate flexible but non-stretchable layers for contraction and twisting actuation modes and compliant electrodes for self-sensing.We further demonstrate that this class of artificial muscles shows potential for versatile robotic applications,such as carrying a camera for recording videos,gripping or manipulating objects,and climbing a pipe-line. | Jiang Zou Miao Feng Ningyuan Ding Peinan Yan Haipeng Xu Dezhi Yang Nicholas X.Fang Guoying Gu Xiangyang Zhu | 2021 | National Science Review2021,8,10: | 3 |
| 4 | Synchronization of chaos using radial basis functions neural networks显示文摘The Radial Basis Functions Neural Network (RBFNN) is used to establish the model of a response system through the input and output data of the system. The synchronization between a drive system and the response system can be implemented by employing the RBFNN model and state feedback control. In this case, the exact mathematical model, which is the precondition for the conventional method, is unnecessary for implementing synchronization. The effect of the model error is investigated and a corresponding theorem is developed. The effect of the parameter perturbations and the measurement noise is investigated through simulations. The simulation results under different conditions show the effectiveness of the method. | Ren Haipeng Liu Ding | 2007 | Journal of Systems Engineering and Electronics2007,18,1: | 2 |

| 18 | Effect of Titanium,Antimony,Cerium and Carbon Nanotubes on the Morphology and Microhardness of Mg-based Icosahedral Quasicrystal Phase显示文摘For the first time, petal-like and spherical Mg-based icosahedral quasicrystal phase (I-phase) were obtained by introducing Ti, Sb, Ce and C nanotubes into Mg-Zn-Y alloy under normal casting conditions. The formation mechanism and stability criterion of spherical I-phase were discussed. The morphology and microhardness of I-phase and their determinants were studied in this paper. The results show that the different value of microhardness of I-phase could be attributed to the different kinds of the fourth component and its content, and its different innate characters. The final morphology of icosahedral quasicrystalline (IQC) is decided by the size of critical stable radius Rr, the content of the fourth component and degree of undercooling. | Zhifeng Wang, Weimin Zhao, Haipeng Li, Jian Ding, Yongyan Li and Chunyong Liang School of Materials Science and Engineering, Hebei University of Technology, Tianjin 300130, China | 2010 | Journal of Materials Science & Technology2010,26,1: | 1 |
