1Advances on three-dimensional electrodes for micro-supercapacitors:A mini-review显示文摘Owing to the high power density,long cycle life and maintain-free,micro-supercapacitors(MSCs)stand out as preferred miniaturized energy source for themiscellaneous autonomous electronic components.However,the shortage of energy density is the main stumbling block for their practical applications.To solve this energy issue,constructing a three-dimensional(3D)electrode within the limited footprint area is proposed as a new solution for improving the energy storage capacity ofMSCs.In the last few years,extensive efforts have been devoted to developing 3D electrodes for MSCs,and significant progress and breakthrough have been achieved.While,there is still lack of systematic summary on the 3D electrode design strategies.To this end,it is imperative to outline the basic design conception,summarize the current states,and discuss the future research about 3D electrodes in MSCs based on the latest development.Long Liu Huaping Zhao Yong Lei 2019InfoMat2019,1,1:11

3Immunity-and-matrix-regulatory cells derived from human embryonic stem cells safely and effectively treat mouse lung injury and fibrosis显示文摘Lung injury and fibrosis represent the most significant outcomes of severe and acute lung disorders,including COVID-19.However,there are still no effective drugs to treat lung injury and fibrosis.In this study,we report the generation of clinical-grade human embryonic stem cells(hESCs)-derived immunity-and matrix-regulatory cells(IMRCs)produced under good manufacturing practice requirements,that can treat lung injury and fibrosis in vivo.We generate IMRCs by sequentially differentiating hESCs with serum-free reagents.IMRCs possess a unique gene expression profile distinct from that of umbilical cord mesenchymal stem cells(UCMSCs),such as higher expression levels of proliferative,immunomodulatory and anti-fibrotic genes.Moreover,intravenous delivery of IMRCs inhibits both pulmonary inflammation and fibrosis in mouse models of lung injury,and significantly improves the survival rate of the recipient mice in a dose-dependent manner,likely through paracrine regulatory mechanisms.IMRCs are superior to both primary UCMSCs and the FDA-approved drug pirfenidone,with an excellent efficacy and safety profile in mice and monkeys.In light of public health crises involving pneumonia,acute lung injury and acute respiratory distress syndrome,our findings suggest that IMRCs are ready for clinical trials on lung disorders.Jun Wu Dingyun Song Zhongwen Li Baojie Guo Yani Xiao Wenjing Liu Lingmin Liang Chunjing Feng Tingting Gao Yanxia Chen Ying Li Zai Wang Jianyan Wen Shengnan Yang Peipei Liu Lei Wang Yukai Wang Liang Peng Glyn Nigel Stacey Zheng Hu Guihai Feng Wei Li Yan Huo Ronghua Jin Ng Shyh-Chang Qi Zhou Liu Wang Baoyang Hu Huaping Dai Jie Hao 2020Cell Research2020,30,9:7

5Atomistic insight into ordered defect superstructures at novel grain boundaries in CuO nanosheets: From structures to electronic properties显示文摘Determining atomistic structures of grain boundaries (GBs) is essential to understand structure--property interplay in oxides.Here,different GB superstructures in CuO nanosheets,including (111) and (114) twinning boundaries (TBs) and (002)/(223) GB,are investigated.Unlike the lower-energy stoichiometric (111) TB,both experimental and first-principles investigations reveal a severe segregation of Cu and O vacancies and a nonstoichiometric property at (114) TB,which may facilitate ionic transportation and provide space for elemental segregation.More importantly,the calculated electronic structures have shown the increased conductivity as well as the unanticipated magnetism in both (114) TB and (002)/(223) GB.These findings could contribute to the race towards the property-directing structural design by GB engineering.Lulu Zhao Lei Li Huaping Sheng He Zheng Shuangfeng Jia Weiwei Meng Huihui Liu Fan Cao Huayu Peng Jianbo Wang 2019Nano Research2019,12,5:5

7Unexpected intercalation-dominated potassium storage in WS2 as a I potassium-ion battery anode显示文摘Unexpected intercalation-dominated process is observed duri ng K^+insertion in WS2 in a voltage range of 0.01-3.0 V.This is different fromthe previously reported two-dimensional(2D)transition metal dichalcogenides that undergo a conversion reaction in a low voltage rangewhen used as anodes in potassium-ion batteries.Charge/discharge processes in the K and Na cells are studied in parallel to demonstrate thedifferention storage mechanisms.The Na^+storage proceeds through intercalation and conversion reactions while the K^+storage is governedby an intercalation reaction.Owing to the reversible K^+intercalation in the van der Waals gaps,the WS2 anode exhibits a low decay rate of 0.07%per cycle,delivering a capacity of 103 mAh·g^-1 after 100 cycles at 100 mA·g^-1.It maintains 57%capacity at 800 mA·g^-1 and shows stablecyclability up to 400 cycles at 500 mA·g^-1.Kinetics study proves the facilitation of K^+transport is derived from the intercalation-dominatedmecha nism.Furthermore,the mechanismis verified by the density functional theory(DFT)calculations,showing that the progressive expansion of the interlayer space can account for the observed results.Vuhan Wu Yang Xu Yueliang Li Pengbo Lyu Jin Wen Chenglin Zhang Min Zhou Yaoguo Fang Huaping Zhao Ute Kaiser Yong Lei 2019Nano Research2019,12,12:3
8Anode materials for potassium-ion batteries: Current status and prospects显示文摘Potassium-ion batteries(KIBs)as one of the most promising alternatives to lithium-ion batteries have been highly valued in recent years.However,progress in KIBs is largely restricted by the sluggish development in anode materials.Therefore,it is imperative to systematically outline and evaluate the recent research advances in the field of anode materials for KIBs toward promoting the development of high-performance anode materials for KIBs.In this review,the recent achievements in anode materials for KIBs are summarized.The electrochemical properties(ie.charge storage mechanism,capacity,rate performance,and cycling stability)of these reported anode materials,as well as their advantages/disadvantages,are discerned and analyzed,enabling high-performance KIBs to meet the requirements for practical applications.Finally,technological developments,scientific challenges,and future research opportunities of anode materials for KIBs are briefly reviewed.Mo Sha Long Liu Huaping Zhao Yong Lei 2020Carbon Energy2020,2,3:3
9Highly-rough surface carbon nanofibers film as an effective interlayer for lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)battery with a new configuration is demonstrated by inserting a flexible nitrogen-doping carbon nanofiber(N-CNFs)interlayer between the sulfur cathode and the separator.The N-CNFs film with high surface roughness and surface area is fabricated by electrospinning and a subsequent calcination process.The N-CNFs film interlayer not only effectively traps the shuttling migration of polysulfides but also gives the whole battery reliable electronic conductivity,which can effectively enhance the electrochemical performance of Li–S batteries.Finally,Li–S batteries with long cycling stability of 785 mAh/g after 200 cycles and good rate capability of 573 mAh/g at 5 C are achieved.Hongfan Zhu Mo Sha Huaping Zhao Yuting Nie Xuhui Sun Yong Lei 2020Journal of Semiconductors2020,41,9:3
10Micro-nano structural electrode architecture for high power energy storage显示文摘The necessity and superiorities of micro-nano structural electrodes toward high power:Electrochemical energy storage(EES)technologies have achieved great success in portable electronics and electric vehicles owing to their environmental friendliness and cost effectiveness.With the promotional concepts such as the Internet of Things and ultra-high efficiency self-powered systems in recent years,there are substantial demand for superior EES systems,including but not limited to high-performance,miniaturization and multifunction[1−4].In a particular EES cell,active materials are carried by electrodes as the basic building blocks of energy storage or release.Material innovation(includes composition,structure,size and morphology)has revealed remarkable energy density,power density and lifespan for associated devices in the lab setting of low mass loading slurry-coating electrodes[5].Xin Chao Chengzhan Yan Huaping Zhao Zhijie Wang Yong Lei 2023Journal of Semiconductors2023,44,5:2

12Forming process and numerical simulation of making upset on oil drill pipe显示文摘The flow stress behavior of grade G-105 steel(API standard) for oil drill pipe in hot compressive deformation was studied by isothermal compression tests on Gleeble-1500 thermal-mechanical machine.Referring to established empirical formulas,the constitutive equation of the flow stress for G-105 steel was obtained.For the grade G-105 oil drill pipe(φ114.3×10.92 mm),through proper design of the die and applying suitable process parameters,and using coupled rigid viscoplastic thermo-mechanical finite element method,the forming process of making upset on oil drill pipe was numerically simulated.The simulation results show that the internal transition section of the oil drill pipe is not only continuous and smooth but also long(up to about 220-250 mm).Huaping TANG Changqian HAO Yongzheng JIANG Lei DU 2010Acta Metallurgica Sinica(English Letters)2010,23,1:1

14Effects of direct aging treatment on microstructure,mechanical properties and residual stress of selective laser melted AlSi10Mg alloy显示文摘Direct aging treatment is an important post-processing procedure,yet little research has been done on how it balances the mechanical properties and the stress removal for selective laser melted(SLMed)AlSi10Mg alloys.Here,we proposed a typical direct aging treatment on SLMed AlSi10Mg alloys,and studied the effects on their microstructure,properties and residual stress evolution.The results indi-cate that the as-built microstructure is mainly composed of fine cellularα-Al and reticulated Si phases,and some pre-existing precipitates and dislocations are found in these cells.The direct aging treatment promotes the precipitation of nano-scaled Si phases and preserves a network-like Si structure.Therefore,the strength of the peak-aged alloy increases while the ductility decreases.As the aging temperature in-creases from 160 to 200℃,aging hardening behavior was accelerated significantly.Aging at 160℃ for 4-9 h removes 32.0%-43.0%of the residual stress,which is attributed to the decomposition of the su-persaturatedα-Al matrix,the precipitation of the nano-Si phase and the exposure of low-angle grain boundaries(LAGBs).Considering the overal alloy performance obtained,over-aging at 160℃ for 4 h is the optimized heat treatment regime.Under this condition,the yield strength(YS),ultimate tensile strength(UTS)and elongation(EL)of the alloy in the transverse and longitudinal direction are 309.5 MPa,464.4 MPa and 8.3%and 286.4 MPa,464.9 MPa and 5.1%,respectively.Huaping Tang Chaofeng Gao Yong Zhang Nannan Zhang Chuan Lei Yunjie Bi Ping Tang Jeremy Heng Rao 2023Journal of Materials Science & Technology2023,,8:1

17Emerging smart design of electrodes for micro-supercapacitors:A review显示文摘Owing to high power density and long cycle life,micro-supercapacitors(MSCs)are regarded as a prevalent energy storage unit for miniaturized electronics in modern life.A major bottleneck is achieving enhanced energy density without sacrificing both power density and cycle life.To this end,designing electrodes in a“smart”way has emerged as an effective strategy to achieve a trade-off between the energy and power densities of MSCs.In the past few years,considerable research efforts have been devoted to exploring new electrode materials for high capacitance,but designing clever configurations for electrodes has rarely been investigated from a structural point of view,which is also important for MSCs within a limited footprint area,in particular.This review article categorizes and arranges these“smart”design strategies of electrodes into three design concepts:layer-by-layer,scaffoldassisted and rolling origami.The corresponding strengths and challenges are comprehensively summarized,and the potential solutions to resolve these challenges are pointed out.Finally,the smart design principle of the electrodes of MSCs and key perspectives for future research in this field are outlined.Jiajia Qiu Huaping Zhao Yong Lei 2022SmartMat2022,3,3:1

19Recent progress and future prospects of high-entropy materials for battery applications显示文摘Due to the energy crisis caused by limited fossil fuel reserves,extensive use of the renewable energy sources such as wind or solar energy is deemed to replace the use of traditional fossil fuels in the future^([1−3]).However,most renewable energy sources face the same problem,which is the intermittency of energy.For example,solar energy cannot be utilized at night.That means the continuous energy demand required for large-scale power grids can’t be satisfied by a single solar panel model.Wenbo Qiu Zidong Wang Shijiang He Huaping Zhao Yong Lei 2024Journal of Semiconductors2024,45,3:0
20Hierarchical Sb-Ni nanoarrays as robust binder-free anodes for high-performance sodium-ion half and full cells显示文摘A novel hierarchical electrode material for Na-ion batteries composed of Sbnanoplates on Ni nanorod arrays is developed to tackle the issues of the rapidcapacity fading and poor rate capability of Sb-based materials. The three-dimensional (3D) Sb-Ni nanoarrays as anodes exhibit the synergistic effects ofthe two-dimensional nanoplates and the open and conductive array structureas well as strong structural integrity. Further, their capacitive behavior isconfirmed through a kinetics analysis, which shows that their excellent Na-storageperformance is attributable to their unique nanostructure. When used asbinder-free sodium-ion battery (SIB) anodes, the nanoarrays exhibit a highcapacity retention rate (more than 80% over 200 cycles) at a current density of0.5 A.g-1 and excellent rate capacity (up to 20 A·g^-1), with their capacity being580 mAh-g-1. Moreover, a P2-Na2/3Nil/3Mn2/302//3D Sb-Ni nanoarrays full celldelivers a highly reversible capacity of 579.8 mAh.g-1 over 200 cycles and an energydensity as high as 100 Wh-kg^-1 This design strategy for ensuring fast and stableNa storage may work with other electrode materials as well.Liying Liang Yang Xu Liaoyong Wen Yueliang Li Min Zhou Chengliang Wang Huaping Zhao Ute Kaiser Yong Lei 2017Nano Research2017,10,9:0
