| 1 | Magnetically levitated/piezoelectric/triboelectric hybrid generator as a power supply for the temperature sensor显示文摘The combination of new intelligent materials and structure technology is becoming an effective way in energy havesting and self-powered sensing. In this work, we demonstrate a magnetically levitated/piezoelectric/triboelectric hybrid generator, which does not use complex structure and has high steady output performance. It includes three parts: magnetically levitated generator(MLG), piezoelectric generator(PNG), triboelectric nanogenerator(TENG). The peak power of each is 135 μW, 22 mW and3.6 mW, which are obtained at 1 MΩ, 10 kΩ and 1 kΩ, respectively. The hybrid generator can completely light up light-emitting diodes(LEDs) under the vibration frequency of 20 Hz and the vibration amplitude of 10 mm. It also can charge a 470 μF capacitor.On this basis, we have integrated the hybrid generaor as a power supply into a self-powered tempreature sensing system. The combination of three generators can not only broaden the operating range, but also increase the operating length and sensitivity.This work will extend the application of self-powered sensor in automatic production line and promote the development of industrial control technology. | ZHANG ZengXing HE Jian HAN JianQiang XU HongYan MU JiLiang WEN Tao WANG DaWei TIAN ZhuMei CHEN ZeTian XUE ChenYang | 2017 | Science China(Technological Sciences)2017，60，7： | 3 |
| 2 | A stretchable triboelectric generator with coplanar integration design of energy harvesting and strain sensing显示文摘The rapid development of flexible triboelectric nanogenerators(TENGs)has become an alternative to batteries for wearable devices.Stretchable,multifunctional,and low-cost are the primary development directions for these wearable devices based on TENG.Herein,a stretchable triboelectric generator with coplanar integration was designed for energy harvesting and force sensing.The industrial conductive silicone and silicone were used to fabricate the TENG with a thickness of less than 0.9 mm.When the elongation was less than 150%,TENG exhibited excellent linear characteristics in the resistance-tensile strain correspondence,and the coefficient of determination was 0.99.This stretchable TENG with a sufficient contact area of 9 cm^(2) could generate a short-circuit current of 2μA when it was in contact with the skin.Lastly,an intelligent tension monitoring wearable device that can effectively measure the tensile force was developed.Such a stretchable,coplanar integration-based,and low-cost wearable device has excellent applicability in wearable electronics. | WU Bin ZHANG ZengXing XUE XiaoBin HAO CongCong ZHANG WenJun BI RuiYu WANG Qiang XUE ChenYang | 2022 | Science China(Technological Sciences)2022，65，1： | 3 |
| 3 | Coil-levitated hybrid generator for mechanical energy harvesting and wireless temperature and vibration monitoring显示文摘The development of wireless monitoring is currently restricted by the short lifetime of batteries,requiring frequent replacement.Utilization of abundant mechanical energy from the surrounding environment has attracted increasing attention in real-time monitoring.Herein,a coil-levitated hybrid generator was developed for the efficient harvesting of mechanical energy from mechanical motion.The novel coil-levitated structure adapted to the metal and magnetic environment.The output currents were systematically analyzed at different operation modes based on the unique combination of triboelectrification,electromagnetic induction,and piezoelectric effect.Under the excitation of vibration frequency and amplitude of 8 Hz and 5 mm respectively,the as-constructed triboelectric nanogenerator delivered a peak power density of 11.40 W/m3 at 10 MΩ.Meanwhile,the middle electromagnetic part and bottom piezoelectric generator provided peak power densities of 6.97 and 79.93 W/m2 at 10000Ω,respectively.More importantly,the battery charging experiment was verified,in which a 30 mA h Li-ion battery can be charged from 2.57 to 3.27 V in about 90 min.In sum,a self-powered temperature and vibration monitoring system was successfully developed based on hybrid generator,promising for realizing wireless monitoring of mechanical equipment without any external power supply. | XUE XiaoBin ZHANG ZengXing WU Bin HE ShanShan WANG Qiang ZHANG WenJun BI RuiYu CUI Juan ZHENG YongQiu XUE ChenYang | 2021 | Science China(Technological Sciences)2021，64，6： | 2 |
| 4 | Synergistic effect of the metal-support interaction and interfacial oxygen vacancy for CO_(2) hydrogenation to methanol over Ni/In_(2)O_(3) catalyst:A theoretical study显示文摘Indium oxide supported nickel catalyst has been experimentally confirmed to be highly active for CO_(2) hydrogenation towards methanol.In this work,the reaction mechanism for CO_(2) hydrogenation to methanol has been investigated on a model Ni/In_(2)O_(3) catalyst,i.e.,Ni_(4)/In_(2)O_(3),via the density functional theory(DFT)study.Three possible reaction pathways,i.e.,the formate pathway,CO hydrogenation and the reverse water-gas-shift(RWGS)pathways,have been examined on this model catalyst.It has been demonstrated that the RWGS pathway is the most theoretically-favored for CO_(2) hydrogenation to methanol.The complete RWGS pathway follows CO_(2)+6 H→COOH+5 H→CO+H_(2)O+4 H→HCO+H_(2)O+3 H→H_(2)CO+H_(2)O+2 H→H_(3)CO+H_(2)O+H→H_(3)COH+H_(2) O.Furthermore,it has been also proved that the interfacial oxygen vacancy can serve as the active site for boosting the CO_(2) adsorption and charge transfer between the nickel species and indium oxide,which synergistically promotes the consecutive CO_(2) hydrogenation towards methanol. | Chenyang Shen Qianqian Bao Wenjuan Xue Kaihang Sun Zhitao Zhang Xinyu Jia Donghai Mei Chang-jun Liu | 2022 | Journal of Energy Chemistry2022，31，2： | 2 |
| 5 | Recent Advances in Molybdenum-Based Materials for Lithium-Sulfur Batteries显示文摘Lithium-sulfur(Li-S)batteries as power supply systems possessing a theoretical energy density of as high as 2600 Wh kg−1 are considered promising alternatives toward the currently used lithium-ion batteries(LIBs).However,the insulation characteristic and huge volume change of sulfur,the generation of dissolvable lithium polysulfides(LiPSs)during charge/discharge,and the uncontrollable dendrite formation of Li metal anodes render Li-S batteries serious cycling issues with rapid capacity decay.To address these challenges,extensive efforts are devoted to designing cathode/anode hosts and/or modifying separators by incorporating functional materials with the features of improved conductivity,lithiophilic,physical/chemical capture ability toward LiPSs,and/or efficient catalytic conversion of LiPSs.Among all candidates,molybdenum-based(Mo-based)materials are highly preferred for their tunable crystal structure,adjustable composition,variable valence of Mo centers,and strong interactions with soluble LiPSs.Herein,the latest advances in design and application of Mo-based materials for Li-S batteries are comprehensively reviewed,covering molybdenum oxides,molybdenum dichalcogenides,molybdenum nitrides,molybdenum carbides,molybdenum phosphides,and molybdenum metal.In the end,the existing challenges in this research field are elaborately discussed. | Henghan Dai Lumin Wang Yue Zhao Jialu Xue Ruicong Zhou Chenyang Yu Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Research2021，，1： | 1 |
| 6 | A joint call for actions to advance taxonomy in China显示文摘Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China. | Chaodong Zhu Arong Luo Ming Bai Michael COrr Zhonge Hou Siqin Ge Jun Chen Yibo Hu Xuming Zhou Gexia Qiao Hongzhi Kong Limin Lu Xiaohua Jin Lei Cai Xinli Wei Ruilin Zhao Wei Miao Qingfeng Wang Zhongli Sha Qiang Lin Meng Qu Jianping Jiang Jiatang Li Jing Che Xuelong Jiang Xiaoyong Chen Lianming Gao Zongxin Ren Chunlei Xiang Shixiao Luo Donghui Wu Dong Liu Yanqiong Peng Tao Su Chenyang Cai Tianqi Zhu Wanzhi Cai Xingyue Liu Hu Li Huaijun Xue Zhen Ye Xuexin Chen Pu Tang Shujun Wei Hong Pang Qiang Xie Feng Zhang Feng Zhang Xianjin Peng Aibing Zhang Taiping Gao Changfa Zhou Chen Shao Libin Ma Zhaoming Wei Yunxia Luan Ziwei Yin Wu Dai Cong Wei Xiaolei Huang Jingxian Liu Xiangsheng Chen Tianci Yi Zhisheng Zhang Zhulidezi Aishan Qin Li Hongying Hu | 2022 | Zoological Systematics2022，47，3： | 1 |

| 9 | Mesh-like vertical structures enable both high areal capacity and excellent rate capability显示文摘In order to balance electrochemical kinetics with loading level for achieving efficient energy storage with high areal capacity and good rate capability simultaneously for wearable electronics,herein,2 D meshlike vertical structures(NiCo_2 S_4@Ni(OH)_2) with a high mass loading of 2.17 mg cm^(-2) and combined merits of both 1 D nanowires and 2 D nanosheets are designed for fabricating flexible hybrid supercapacitors.Particularly,the seamlessly interconnected NiCo_2 S_4 core not only provides high capacity of 287.5 μAh cm^(-2) but also functions as conductive skeleton for fast electron transport;Ni(OH)_2 sheath occupying the voids in NiCo_2 S_4 meshes contributes extra capacity of 248.4 μAh cm^(-2);the holey features guarantee rapid ion diffusion along and across NiCO_2 S_4@Ni(OH)_2 meshes.The resultant flexible electrode exhibits a high areal capacity of 535.9 μAh cm^(-2)(246.9 mAh g^(-1)) at 3 mA cm^(-2) and outstanding rate performance with 84.7% retention at 30 mA cm^(-2),suggesting efficient utilization of both NiCo_2 S_4 and Ni(OH)_2 with specific capacities approaching to their theoretical values.The flexible solid-state hybrid device based on NiCo_2 S_4@Ni(OH)_2 cathode and Fe_2 O_3 anode delivers a high energy density of 315 μWh cm^(-2) at the power density of 2.14 mW cm^(-2) with excellent electrochemical cycling stability. | Ruyi Chen Jialu Xue Yujiao Gong Chenyang Yu Zengyu Hui Hai Xu Yue Sun Xi Zhao Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Journal of Energy Chemistry2021，30，2： | 1 |

| 20 | Porous monoliths of 3D graphene for electric double-layer supercapacitors显示文摘For delivering the nanoscaled extraordinary characteristics in macroscopical bulk,it is essential to integrate two-dimensional nanosheets into threedimensional(3D)porous monoliths,alternatively called as 3D architectures,3D networks,or aerogels.The intersupported structure of porous monolithic 3D graphene(3DG)can prevent aggregation or restacking of graphene individuals,and the interconnected sp^(2) network of 3DG not only can provide the highway for the transport of electron/phonon but also can present continual cavities/channels for mass transfer.This review summarizes the synthesis methodology of 3DG porous monoliths and highlights the application for electric double-layer capacitors.Present challenges and future prospects about the manufacture and application of 3DG are also discussed. | Jinjue Zeng Chenyang Xu Tian Gao Xiangfen Jiang Xue‐Bin Wang | 2021 | Carbon Energy2021，3，2： | 1 |
