| 2 | B-doped and La_(4)NiLiO_(8)-coated Ni-rich cathode with enhanced structural and interfacial stability for lithium-ion batteries显示文摘Ni-rich layered oxides are considered promising cathodes for advanced lithium-ion batteries(LIBs)in the future,owing to their high capacity and low cost.However,the issues on structural and interfacial stability of Ni-rich cathodes still pose substantial obstacles in the practical application of advanced LIBs.Here,we employ a one-step method to synthesize a B-doped and La_(4)NiLiO_(8)-coated LiNi_(0.82)5Co_(0.115)Mn_(0.06)O_(2)(BL-1)cathode with reliable structure and interface,for the first time.The La_(4)NiLiO_(8)coating layer can prevent cathodes from electrolyte assault and facilitate Li+diffusion kinetics.Moreover,B-doping can effectively restrain the pernicious H_(2)-H_(3) phase transition and adjust the orientation of primary particles to a radial alignment,which is obstructive to the arise of microcracks induced by the change of anisotropic volume.Specifically,when tested in pouch cells,the BL-1 cathode exhibits outstanding capacity retention of 93.49%after 500 cycles at 1 C.This dual-modification strategy dramatically enhances the stability of the structure and interface for Ni-rich cathode materials,consequently accelerating the commercialization process of high-energy–density LIBs. | Lingjun Li Lizhi Fu Miao Li Chu Wang Zixiang Zhao Shangchen Xie Haichen Lin Xianwen Wu Haodong Liu Li Zhang Qiaobao Zhang Lei Tan | 2022 | Journal of Energy Chemistry2022，31，8： | 10 |

| 4 | Achieving high-capacity and long-life K^(+)storage enabled by constructing yolk-shell Sb_(2)S_(3)@N,S-doped carbon nanorod anodes显示文摘As promising anode candidates for potassium-ion batteries(PIBs),antimony sulfide(Sb_(2)S_(3))possesses high specific capacity but suffers from massive volume expansion and sluggish kinetics due to the large K^(+)insertion,resulting in inferior cycling and rate performance.To address these challenges,a yolk-shell structured Sb_(2)S_(3)confined in N,S co-doped hollow carbon nanorod(YS-Sb_(2)S_(3)@NSC)working as a viable anode for PIBs is proposed.As directly verified by in situ transmission electron microscopy(TEM),the buffer space between the Sb_(2)S_(3)core and thin carbon shell can effectively accommodate the large expansion stress of Sb_(2)S_(3)without cracking the shell and the carbon shell can accelerate electron transport and K^(+)diffusion,which plays a significant role in reinforcing the structural stability and facilitating charge transfer.As a result,the YS-Sb_(2)S_(3)@NSC electrode delivers a high reversible K^(+)storage capacity of 594.58 m A h g^(-1)at 0.1 A g^(-1)and a long cycle life with a slight capacity degradation(0.01%per cycle)for 2000 cycles at 1 A g^(-1)while maintaining outstanding rate capability.Importantly,utilizing in in situ/ex situ microscopic and spectroscopic characterizations,the origins of performance enhancement and K^(+)storage mechanism of Sb_(2)S_(3)were clearly elucidated.This work provides valuable insights into the rational design of high-performance and durable transition metal sulfides-based anodes for PIBs. | Bensheng Xiao Hehe Zhang Zhefei Sun Miao Li Yingzhu Fan Haichen Lin Haodong Liu Bing Jiang Yanbin Shen Ming-Sheng Wang Meicheng Li Qiaobao Zhang | 2023 | Journal of Energy Chemistry2023，，1： | 1 |
| 5 | Atomic mechanisms of hexagonal close-packed Ni nanocrystallization revealed by in situ liquid cell transmission electron microscopy显示文摘The fundamental understanding of the mechanism underlying the early stages of crystallization of hexagonal-close-packed(hcp)nanocrystals is crucial for their synthesis with desired properties,but it remains a significant challenge.Here,we report using in situ liquid cell transmission electron microscopy(TEM)to directly capture the dynamic nucleation process and track the real-time growth pathway of hcp Ni nanocrystals at the atomic scale.It is demonstrated that the growth of amorphous-phase-mediated hcp Ni nanocrystals is from the metal-rich liquid phases.In addition,the reshaped preatomic facet development of a single nanocrystal is also imaged.Theoretical calculations further identify the non-classical features of hcp Ni crystallization.These discoveries could enrich the nucleation and growth model theory and provide useful information for the rational design of synthesis pathways of hcp nanocrystals. | Junyu Zhang Miao Li Zewen Kang Bensheng Xiao Haichen Lin Jingyu Lu Haodong Liu Xue Zhang Dong-Liang Peng Qiaobao Zhang | 2022 | Nano Research2022，15，7： | 0 |
| 6 | Positioning Analysis of AY Field Brand显示文摘For a considerable duration,the traditional dairy product market in China has been dominated by a dual oligopoly,primarily led by Mengniu and Yili.Regional brands such as Guangming,Junlebao,and Sanyuan have engaged in staggered competition,contributing to a pattern of feudal separatism among local brands.AY Group,positioned as a significant independent player in the China dairy industry,has strategically extended its reach downstream in the supply chain,establishing the consumer brand AY Field.Despite possessing a robust advantage in self-owned ranches and delivering high-quality products,AY Field grapples with challenges related to unclear market positioning and low brand awareness among final consumers.This study employs a SWOT analysis to delve into identifying a market positioning strategy that best suits the AY Field brand.The research reveals that the current dynamics of competition in the dairy industry market are predominantly concentrated in the high-end and low-end segments,leaving a noticeable gap in the middle market.Leveraging the natural,high-quality,and competitively priced attributes of AY Field milk,the recommended market position involves supplying ambient liquid milk that aligns with the consumption habits of young individuals and office workers.This strategic positioning aims to offer high-quality products at moderate prices,addressing the specific needs of the identified consumer demographic. | Haichen Ding Xuehua Lin Ping Yu Lingfan Zhang Qinjing Fan | 2023 | Proceedings of Business and Economic Studies2023，6，6： | 0 |
| 7 | Analysis of AY Field Brand Planning Based on Raw Milk Traceability显示文摘Mengniu and Yili have virtually monopolized the traditional Chinese dairy market,while new media marketing and digital strategies have opened up substantial business opportunities for emerging brands.Leveraging a differentiation strategy,the Adopt A Cow brand has successfully carved out its niche in the market,serving as an exemplary example.However,AY Field,as a self-owned brand by a supplier,faces the challenge of low product awareness among end consumers.This paper primarily concentrates on brand planning for the AY Field milk brand,with a focus on positioning the product for mid-range consumers,including students and office workers.The strategy involves the development of a new logo and packaging design,the selection of sports stars as brand ambassadors,and the implementation of innovative online sales promotions to bolster brand awareness and competitiveness.Research indicates that incorporating raw milk traceability and digital technology to establish a product brand with transparent ranches can significantly enhance AY Field’s competitive edge,facilitating the execution of a differentiated marketing strategy. | Haichen Ding Lingfan Zhang Ping Yu Xuehua Lin Qinjing Fan | 2023 | Proceedings of Business and Economic Studies2023，6，6： | 0 |
| 8 | Understanding the growth mechanisms of metal-based core–shell nanostructures revealed by in situ liquid cell transmission electron microscopy显示文摘Metal-based core-shell nanostructures have garnered enduring interest due to their unique properties and functionalities.However,their growth and transformation mechanisms in liquid media remain largely unknown because they lack direct observation of the dynamic growth process with high spatial and temporal resolution.Developing the in situ liquid cell transmission electron microscopy(TEM)technique offers unprecedented real-time imaging and spectroscopy capabilities to directly track the evolution of structural and chemical transformation of metal-based core–shell nanostructures in liquid media under their working condition.Here,this review highlights recent progress in utilizing in situ liquid cell TEM characterization technique in investigating the dynamic evolution of material structure and morphology of metal-based core–shell nanostructures at the nano/atomic scale in real-time.A brief introduction of the development of liquid cells for in situ TEM is first given.Subsequently,recent advances in in situ liquid cell TEM for the fundamental study of growth mechanisms of metal based core–shell nanostructures are discussed.Finally,the challenge and future developments of metalbased core–shell nanostructures for in situ liquid cell TEM are proposed.Our review is anticipated to inspire ongoing interest in revealing unseen growth dynamics of core–shell nanostructures by in situ liquid cell TEM technique. | Junyu Zhang Bensheng Xiao Junhui Zhao Miao Li Haichen Lin Zewen Kang Xianwen Wu Haodong Liu Dong-Liang Peng Qiaobao Zhang | 2022 | Journal of Energy Chemistry2022，31，8： | 0 |
| 9 | A Method of Disc Inclination Correction Based on the Inversion Model of Rotation Law显示文摘Under the traditional dynamic model,the conventional method for solving the rotation angle of a rigid body is to use the fixed-axis rotation law of the rigid body,but the known rotation shaft position must be used as a prerequisite.In practical work,for the rotation of a rigid body under multiple forces,solving the shaft is often a difficult problem.In this paper,we consider the rigid body of the disc is subjected to the force of uneven magnitude from multiple angles,the position of the rotating shaft is obtained by iterative inversion through the rigid body rotation law and the dichotomy method.After the position of the shaft is determined,we establish a differential equation model based on the law of rigid body rotation,the rotation angle of the rigid body thus being solved based on this model.Furthermore,an optimization algorithm such as genetic algorithm is used to search for a correction scheme to return the rigid body to equilibrium at any given deflection angle.The model and method are based on computer to explore the law of rotation,the practical application of them play an important role in studying the concentric drum movement and the balance of handling furniture. | Yanan Zhang Lin Ouyang Qinqin Li Haichen Ju | 2020 | Journal on Big Data2020，2，3： | 0 |
