| 1 | Insulating materials for realising carbon neutrality:Opportunities,remaining issues and challenges显示文摘The 2050 carbon-neutral vision spawns a novel energy structure revolution,and the construction of the future energy structure is based on equipment innovation.Insulating material,as the core of electrical power equipment and electrified transportation asset,faces unprecedented challenges and opportunities.The goal of carbon neutral and the urgent need for innovation in electric power equipment and electrification assets are first discussed.The engineering challenges constrained by the insulation system in future electric power equipment/devices and electrified transportation assets are investigated.Insulating materials,including intelligent insulating material,high thermal conductivity insulating material,high energy storage density insulating material,extreme environment resistant insulating material,and environmental-friendly insulating material,are cat-egorised with their scientific issues,opportunities and challenges under the goal of carbon neutrality being discussed.In the context of carbon neutrality,not only improves the understanding of the insulation problems from a macro level,that is,electrical power equipment and electrified transportation asset,but also offers opportunities,remaining issues and challenges from the insulating material level.It is hoped that this paper en-visions the challenges regarding design and reliability of insulations in electrical equipment and electric vehicles in the context of policies towards carbon neutrality rules.The authors also hope that this paper can be helpful in future development and research of novel insulating materials,which promote the realisation of the carbon-neutral vision. | Chuanyang Li Yang Yang Guoqiang Xu Yao Zhou Mengshuo Jia Shaolong Zhong Yu Gao Chanyeop Park Qiang Liu Yalin Wang Shakeel Akram Xiaoliang Zeng Yi Li Fangwei Liang Bin Cui Junpeng Fang Lingling Tang Yulin Zeng Xingtao Hu Jiachen Gao Giovanni Mazzanti Jinliang He Jianxiao Wang Davide Fabiani Gilbert Teyssedre Yang Cao Feipeng Wang Yunlong Zi | 2022 | High Voltage2022，7，4： | 4 |
| 2 | Mechanical,corrosion and magnetic behavior of a CoFeMn_(1.2)NiGa_(0.8) high entropy alloy显示文摘In this study,a magnetic high entropy alloy(HEA)of CoFeMn_(1.2)NiGa_(0.8)was designed and prepared by arc melting in order to investigate its mechanical,corrosion and magnetic behavior.The results show that the alloy mainly possesses body-centered cubic(BCC)phase and face-centered cubic(FCC)phase.A high compressive strength of 1450 MPa,a strain of 18.5%and a relatively low yield strength of 303MPa in as-cast condition at room temperature can be achieved in the present alloy.In-situ high-energy X-ray diffraction technique was employed to reveal the deformation mechanism of Co Fe Mn_(1.2)Ni Ga_(0.8)under uniaxial compression and the results show that the competition between BCC phase and FCC phase plays a significant role during the compressive process.The corrosion behavior of Co Fe Mn_(1.2)Ni Ga_(0.8)was investigated in 3.5 wt%Na Cl solution and it turned out that the alloy possessed good corrosion resistance.At last,the magnetic behavior of the Co Fe Mn_(1.2)Ni Ga_(0.8)alloy was studied and it can present a high saturation magnetization of 94.5 emu/g and a coercivity of 26.4 Oe at 4 K.This work indicates that the present Co Fe Mn_(1.2)Ni Ga_(0.8)HEA has promising applications as future magnetic functional materials. | Xiaoming Sun Lingzhong Du Hao Lan Jingyi Cui Liang Wang Runguang Li Zhiang Liu Junpeng Liu Weigang Zhang | 2021 | Journal of Materials Science & Technology2021，，14： | 2 |
| 3 | Phase separation-hydrogen etching-derived Cu-decorated Cu-Mn bimetallic oxides with oxygen vacancies boosting superior sodium-ion storage kinetics显示文摘Understanding the crystal phase evolution of bimetallic oxide anodes is the main concern to profoundly reveal the conversion reaction kinetics and sodium-ion storage mechanisms.Herein,an integrated selfsupporting anode of the Cu-decorated Cu-Mn bimetallic oxides with oxygen vacancies(Ov-BMO-Cu)are in-situ generated by phase separation and hydrogen etching using nanoporous Cu-Mn alloy as selfsacrificial templates.On this basis,we have elucidated the relationship between the phase evolution,oxygen vacancies and sodium-ion storage mechanisms,further demonstrating the evolution of oxygen vacancies and the inhibition effect of manganese oxides as an“anchor”on grain aggregation of copper oxides.The kinetic analyses confirm that the expanded lattice space and increased oxygen vacancies of cycled Ov-BMO-Cu synergistically guarantee effective sodium-ion diffusion and storage mechanisms.Therefore,the Ov-BMO-Cu electrode exhibits higher reversible capacities of 4.04 mA h cm^(-2)at 0.2 mA cm^(-2)after 100 cycles and 2.20 m A h cm^(-2)at 1.0 mA cm^(-2)after 500 cycles.Besides,the presodiated Ov-BMO-Cu anode delivers a considerable reversible capacity of 0.79 m A h cm^(-2)at 1.0 mA cm^(-2)after 60 cycles in full cells with Na_(3)V_(2)(PO_(4))_(3)cathode,confirming its outstanding practicality.Thus,this work is expected to provide enlightenment for designing high-capacity bimetallic oxide anodes. | Lin Yan Lingshuo Zong Qi Sun Junpeng Guo Zhenyang Yu Zhijun Qiao Jiuhui Han Zhenyu Cui Jianli Kang | 2023 | Journal of Energy Chemistry2023，，5： | 1 |
| 4 | High-performance triboelectric nanogenerator based on theoretical analysis and ferroelectric nanocomposites and its high-voltage applications显示文摘With the growing economy and technology,disease prevention and individual health are becoming more and more important.It is highly urgent to develop a non-toxic,self-powered,and safe high-voltage power source to prevent diseases spread by mosquitoes,especially in isolated or remote areas.Herein,we reported a high-performance rotary triboelectric nanogenerator(R-TENG)based on customized theoretical simulations and a ferroelectric nanocomposite intermediate layer.The customized theoretical simulations based on gradient electrode gaps were established to optimize gap angles and segment numbers of the electrodes,which could prevent air breakdown and enhance the R-TENG output energy by at least 1.5 times.Meanwhile,the electrical output performance of the TENG was further enhanced with a highly oriented BaTiO3(BTO)nanoparticles intermediate layer by about 2.5 times.The open-circuit voltage of R-TENG reached more than 6 kV and could continuously light 3420 light-emitting devices(LEDs)or 4 serially connected 36 W household fluorescent lamps.Therefore,a self-powered high-voltage disease prevention system is developed based on the high-performance R-TENG to reduce the risk of disease transmission.This work provides a prospective strategy for the further development of TENGs and expands practical applications of self-powered and high-voltage systems. | Xuhua Guo Jianwei He Yang Zheng Junpeng Wu Caofeng Pan Yunlong Zi Hongzhi Cui Xiaoyi Li | 2023 | Nano Research Energy2023，2，3： | 1 |

| 6 | Quiet rest ameliorates biochemical metabolism in the brain in a simple concussion rabbit model Evaluation of hydrogen proton magnetic resonance spectroscopy显示文摘The present study analyzed changes in the biochemical metabolites N-acetyl aspartate, choline, and creatine in a simple concussion rabbit model following quiet rest, hyperbaric oxygen therapy, or interference stimulation through the use of hydrogen proton magnetic resonance spectroscopy detection. Experimental findings showed that brain N-acetyl aspartate and choline peak values significantly decreased, while creatine peak values significantly increased following simple concussion. Following treatments, N-acetyl aspartate and choline peaks returned to normal levels in the quiet rest and hyperbaric oxygen therapy groups, but no changes were observed in the interference stimulation group. Results demonstrated abnormal changes in the brain biochemical metabolism environment following simple concussion. Quiet rest was shown to play an important role in restoration of biochemical metabolism following simple concussion. | Lin Ouyang Yuhui Xiao Cui Yue Junpeng Ma Rongyue Shi Lin Gao Yihe Guo Jiarong Meng Qianxin Jia | 2011 | Neural Regeneration Research2011，6，33： | 0 |
| 7 | Exploiting ultra-large linear elasticity over a wide temperature range in nanocrystalline NiTi alloy显示文摘Many shape memory alloys can support large recoverable strains of a few percent by reversible stressinduced martensite transformation,yet they behave non-linear within a narrow operating temperature ra nge.Developing the bulk metallic materials with ultra-large linear elasticity over a wide tempe rature range has proven to be difficult.In this work,a material design concept was proposed,that is true elastic deformation and reversible twinning-detwinning deformation run in parallel to overcome this challe nge.By engineering the residual internal stress to realize the concurrency of true elastic deformation and twinning-detwinning deformation,a bulk nanocrystalline NiTi that possesses an ultra-large linear elastic strain up to 5.1 % and a high yield stress of 2.16 GPa over a wide temperature range of 270℃ was developed.This study offers a new avenue for developing the metallic materials with ultra-large linear elasticity over a wide temperature range of 270℃(from 70℃ to-197℃). | Zhen Sun Shijie Hao Genfa Kang Yang Ren Junpeng Liu Ying Yang Xiangguang Kong Bo Feng Cheng Wang Kun Zhao Lishan Cui | 2020 | Journal of Materials Science & Technology2020，54，22： | 0 |
