| 1 | Dielectric polymer based electrolytes for high-performance all-solid-state lithium metal batteries显示文摘Solid polymer electrolytes (SPEs) are urgently required for achieving practical all-solid-state lithium metal batteries (ASSLMBs) but remain plagued by low ionic conductivity.Herein,we propose a strategy of salt polarization to fabricate a highly ion-conductive SPE by employing a high-dielectric polymer that can interact strongly with lithium salts.Such a polymer with large dipole moments can guide lithium cations (Li^(+)) to be arranged along the chain,forming a continuous pathway for Li^(+) hopping within the SPE.The as-fabricated SPE,poly(vinylidene difluoride)(PVDF)-LiN(SO_(2)F)_(2)(LiFSI),has an extraordinarily high dielectric constant (up to 10^(8)) and ultrahigh ionic conductivity (0.77×10^(-3)S cm^(-1)).Based on the PVDF–LiFSI SPE,the assembled Li metal symmetrical cell shows excellent Li plating/stripping reversibility at 0.1 m A cm^(-2),0.1 m Ah cm^(-2)over 1500 h^(-1) the ASS LiFePO_(4) batteries deliver long-term cycling stability at 1 C over 350 cycles (2.74 mg cm^(-2)) and an ultralong cycling lifespan of over 2600 h(100 cycles) with high loading (11.5 mg cm^(-2)) at 28°C.First-principles calculations further reveal the ion-dipole interactions-controlled conduction of Li^(+) in PVDF–LiFSI SPE along the PVDF chain.This work highlights the critical role of dielectric permittivity in SPE,and provides a promising path towards high-energy,long-cycling lifespan ASSLMBs. | Qi Kang Yong Li Zechao Zhuang Dingsheng Wang Chunyi Zhi Pingkai Jiang Xingyi Huang | 2022 | Journal of Energy Chemistry2022，31，6： | 7 |
| 2 | Rapid, high-efficient and scalable exfoliation of high-quality boron nitride nanosheets and their application in lithium-sulfur batteries显示文摘Boron nitride nanosheets(BNNSs)have gained significant attraction in energy and environment fields because of their two-dimensional(2D)nature,large band gap and high thermal/mechanical performance.However,the current low production efficiency of high-quality BNNSs is still a bottleneck limiting their applications.Herein,based on sonication-assisted liquid-phase exfoliation,we demonstrated a rapid,high-efficient and scalable production strategy of BNNSs and documented the effects of a spectrum of exfoliation factors(e.g.,ultrasonic condition,solvent and bulk material feeding)on the yield of BNNSs.A record of yield of 72.5%was achieved while the exfoliated BNNSs have few-layer and defect-free feature.Thanks to the Lewis acid sites of the boron atoms,the BNNSs can interact with the polysulfide anions in liquid electrolyte and also can facilitate the uniform lithium deposition,which finally endow a lithium-sulfur(Li-S)battery with long life.This work provides a facile and rapid strategy for large scale preparation of high-quality BNNSs,also contributes a long-life strategy for dendrite-free Li-S battery,opens new avenues of BNNSs in energy application. | Yu Chen Qi Kang Pingkai Jiang Xingyi Huang | 2021 | Nano Research2021，14，7： | 7 |
| 3 | Spider Web‑Inspired Graphene Skeleton‑Based High Thermal Conductivity Phase Change Nanocomposites for Battery Thermal Management显示文摘Phase change materials(PCMs)can be used for efficient thermal energy harvesting,which has great potential for cost-effective thermal management and energy storage.However,the low intrinsic thermal conductivity of polymeric PCMs is a bottleneck for fast and efficient heat harvesting.Simultaneously,it is also a challenge to achieve a high thermal conductivity for phase change nanocomposites at low filler loading.Although constructing a three-dimensional(3D)thermally conductive network within PCMs can address these problems,the anisotropy of the 3D framework usually leads to poor thermal conductivity in the direction perpendicular to the alignment of fillers.Inspired by the interlaced structure of spider webs in nature,this study reports a new strategy for fabricating highly thermally conductive phase change composites(sw-GS/PW)with a 3D spider web(sw)-like structured graphene skeleton(GS)by hydrothermal reaction,radial freeze-casting and vacuum impregnation in paraffin wax(PW).The results show that the sw-GS hardly affected the phase transformation behavior of PW at low loading.Especially,sw-GS/PW exhibits both high cross-plane and in-plane thermal conductivity enhancements of~1260%and~840%,respectively,at an ultra-low filler loading of 2.25 vol.%.The thermal infrared results also demonstrate that sw-GS/PW possessed promising applications in battery thermal management. | Ying Lin Qi Kang Han Wei Hua Bao Pingkai Jiang Yiu‑Wing Mai Xingyi Huang | 2021 | Nano-Micro Letters2021，13，11： | 5 |
| 4 | Manipulating dielectric property of polymer coatings toward highretention-rate lithium metal full batteries under harsh critical conditions显示文摘Lithium(Li)metal batteries(LMBs)can potentially deliver much higher energy density but remain plagued by uncontrollable Li plating with dendrite growth,unstable interfaces,and highly abundant excess Li(>50 mAh·cm^(-2)).Herein,different from the artificial layer or three-dimensional(3D)matrix host constructions,various dielectric polymers are initially well-comprehensively investigated from experimental characterizations to theoretical simulation to evaluate their functions in modulating Li ion distribution.As a proof of concept,a 3D interwoven high dielectric functional polymer(HDFP)nanofiber network with polar C-F dipole moments electrospun on copper(Cu)foil is designed,realizing uniform and controllable Li deposition capacity up to 5.0 mAh·cm^(-2),thereby enabling stable Li plating/stripping cycling over 1400 h at 1.0 mA·cm^(-2).More importantly,under the highcathode loading(~3.1 mAh·cm^(-2))and only 0.6×excess Li(N/P ratio of 1.6),the full cells retain capacity retention of 97.4%after 200 cycles at 3.36 mA·cm^(-2)and achieve high energy density(297.7 Wh·kg^(-1)at cell-level)under lean electrolyte conditions(15μL),much better than ever-reported literatures.Our work provides a new direction for designing high dielectric polymer coating toward high-retention-rate practical Li full batteries. | Qi Kang Zechao Zhuang Yong Li Yinze Zuo Jian Wang Yijie Liu Chaoqun Shi Jie Chen Hongfei Li Pingkai Jiang Xingyi Huang | 2023 | Nano Research2023，16，7： | 3 |
| 5 | Flexible,Highly Thermally Conductive and Electrically Insulating Phase Change Materials for Advanced Thermal Management of 5G Base Stations and Thermoelectric Generators显示文摘Thermal management has become a crucial problem for high-power-density equipment and devices.Phase change materials(PCMs)have great prospects in thermal management applications because of their large capacity of heat storage and isothermal behavior during phase transition.However,low intrinsic thermal conductivity,ease of leakage,and lack of flexibility severely limit their applications.Solving one of these problems often comes at the expense of other performance of the PCMs.In this work,we report core–sheath structured phase change nanocomposites(PCNs)with an aligned and interconnected boron nitride nanosheet network by combining coaxial electrospinning,electrostatic spraying,and hot-pressing.The advanced PCN films exhibit an ultrahigh thermal conductivity of 28.3 W m^(-1)K^(-1)at a low BNNS loading(i.e.,32 wt%),which thereby endows the PCNs with high enthalpy(>101 J g^(-1)),outstanding ductility(>40%)and improved fire retardancy.Therefore,our core–sheath strategies successfully balance the trade-off between thermal conductivity,flexibility,and phase change enthalpy of PCMs.Further,the PCNs provide powerful cooling solutions on 5G base station chips and thermoelectric generators,displaying promising thermal management applications on high-power-density equipment and thermoelectric conversion devices. | Ying Lin Qi Kang Yijie Liu Yingke Zhu Pingkai Jiang Yiu‑Wing Mai Xingyi Huang | 2023 | Nano-Micro Letters2023，15，3： | 2 |
| 6 | Self-cleaning of superhydrophobic nanostructured surfaces at low humidity enhanced by vertical electric field显示文摘Self-cleaning is the key factor that makes superhydrophobic nanostructured materials have wide applications.The self-cleaning effect,however,strongly depends on formations and movement of water droplets on superhydrophobic nanostructured surfaces,which is greatly restricted at low humidity(<7.6 g·kg^(-1)).Therefore,we propose a self-cleaning method at low humidity in which the pollution is electro-aggregated and driven in the electric field to achieve the aggregation and cleaning large areas.The cleaning efficiency of this method is much higher than that of water droplet roll-off,and will not produce'pollution bands'.A simplified numerical model describing pollution movements is presented.Simulation results are consistent with experimental results.The proposed method realizes the self-cleaning of superhydrophobic nanostructured surfaces above dew point curve for the first time,which extends applications of superhydrophobic nanostructured materials in low humidity,and is expected to solve self-cleaning problems of outdoor objects in low humidity areas(<5.0 g·kg^(-1)). | Yijie Liu Yujun Guo Xueqin Zhang Guoqiang Gao Chaoqun Shi Guizao Huang Pengli Li Qi Kang Xingyi Huang Guangning Wu | 2022 | Nano Research2022，15，5： | 1 |

| 9 | Moisture sorption and thermodynamic properties of Camellia oleifera seeds as influenced by oil content显示文摘Moisture sorption isotherms and thermodynamic properties of Camellia oleifera seeds as influenced by oil content were investigated.Moisture desorption and adsorption isotherms of Camellia oleifera seeds,kernels and shells from three varieties were determined using constant temperature and humidity chamber method at different temperatures(10°C,25°C,and 40°C)with water activity ranging from 0.20 to 0.90.Six selected mathematic models were employed to fit the experimental data.The Peleg model gave the best results for both seeds and kernels and Langmuir model was the best for shells.The difference of equilibrium moisture contents at the same water activities during desorption and adsorption indicated the occurrence of hysteresis of adsorption processes and the equilibrium moisture contents tended to decrease with the increasing oil content and temperature.The binding energy and average capacity per unit mass decreased with increasing temperature and oil content.The relationships between water activity and the logarithm of sorption activity showed the capillary porous body characteristics of the seeds. | Guangfei Zhu Qi Jin Yanhong Liu Yawen Lin Jun Wang Xingyi Li | 2021 | International Journal of Agricultural and Biological Engineering2021，14，1： | 1 |
| 10 | Scalable synthesis of A_2S_3 (A=Sb, Bi) submicro/nanowires using their powders via solvothermal proceeding显示文摘Single-crystal A2S3 (A=Sb, Bi) nanowires were successfully prepared via using their powders as precursors by solvothermal proceeding. The reac-tion temperature and time as well as solvent strongly influence final A2S3 crystalline morphology and size. Experimental results show that Sb2S3 rods prepared in ethylene glycol are thicker than its wires with av-erage diameter of 400 nm prepared in the mixture solvent of ethylene glycol and ethylenediamine at 200 oC for 24 h. However, under the same reaction con-dition, uniform submicrowires of Bi2S3 with average diameter of 150 nm can be obtained. When reaction temperature is decreased to 150 oC and reaction time is 40 h, pure Sb2S3 wires cannot be prepared. The possible mechanism is briefly discussed for the transformation of the Sb2S3 powders to their wire-like crystals. | JI Tianhao LIU Guanrao QI Xingyi YANG Qinglin DENG Yuan GUO Lin | 2006 | Chinese Science Bulletin2006，51，6： | 1 |

| 13 | Antimony-Doping Induced Highly Efficient Warm-White Emission in Indium-Based Zero-Dimensional Perovskites显示文摘Indium(In)-based halide perovskites are desirable for next-generation phosphors and emitting devices,due to their broad emission,nontoxicity,and oxidization avoidance capabilities.However,the In-based perovskites always exhibit low external photoluminescence quantum efficiency(PLQE)as a result of their weak light absorption near the corresponding excitation region,and thus,are limited in extended applications.Herein,we have developed an antimony(Sb)-doping strategy to improve the absorption ability of Cs2InCl5·H2O in the ultraviolet region.Excitingly,we obtained a warm-light phosphor with ultrahigh external(internal)PLQE of 72.8%(86.7%).Typically,upon 1.5%Sb doping,the single-crystalline Cs2InCl5·H2O perovskite displayed a stronger warm-light emission at∼610 nm with a large Stokes shift of 295 nm and full width at half maximum(FWHM)of 164 nm.Density functional theory(DFT)calculations revealed that the Sb-doping induced an impurity level in the bandgap,increasing the density of state(DOS),and promoted more carriers into the conduction band maximum.Furthermore,external PLQE from 18%to 59%could be realized in other zero-dimensional In-based perovskites through the same doping strategy. | Xingyi Liu Xi Xu Ben Li Yongqi Liang Qi Li Hong Jiang Dongsheng Xu | 2020 | CCS Chemistry2020，2，2： | 0 |
| 14 | Overlapping community‐based particle swarm optimization algorithm for influence maximization in social networks显示文摘Influence maximization,whose aim is to maximise the expected number of influenced nodes by selecting a seed set of k influential nodes from a social network,has many applications such as goods advertising and rumour suppression.Among the existing influence maximization methods,the community‐based ones can achieve a good balance between effectiveness and efficiency.However,this kind of algorithm usually utilise the network community structures by viewing each node as a non‐overlapping node.In fact,many nodes in social networks are overlapping ones,which play more important role in influence spreading.To this end,an overlapping community‐based particle swarm opti-mization algorithm named OCPSO for influence maximization in social networks,which can make full use of overlapping nodes,non‐overlapping nodes,and their interactive information is proposed.Specifically,an overlapping community detection algorithm is used to obtain the information of overlapping community structures,based on which three novel evolutionary strategies,such as initialisation,mutation,and local search are designed in OCPSO for better finding influential nodes.Experimental results in terms of influence spread and running time on nine real‐world social networks demonstrate that the proposed OCPSO is competitive and promising comparing to several state‐of‐the‐arts(e.g.CGA,CMA‐IM,CIM,CDH‐SHRINK,CNCG,and CFIN). | Lei Zhang Yutong Liu Haipeng Yang Fan Cheng Qi Liu Xingyi Zhang | 2023 | CAAI Transactions on Intelligence Technology2023，8，3： | 0 |
| 15 | Universal precursors dispersed in Vaseline-octadecene gel for nanocrystal synthesis显示文摘A great variety of high-quality inorganic nanocrystals are synthesized solely in hydrocarbon solvents in both academic and industrial settings on a daily basis,which is largely complicated by lack of simple precursors containing inorganic element(s)yet soluble in the reaction solvents at ambient temperatures.Here,we introduce a new strategy for preparing the precursors,namely inorganic(or element-containing organic)molecules dispersed in hydrocarbon(Vaseline-octadecene)gel.This strategy not only greatly expands spectra of potential precursors and their concentration range,but also simplifies synthetic system,enables automated large-scale synthesis,and minimizes environmental concerns. | Yijie Liu Yujun Guo Xueqin Zhang Guoqiang Gao Chaoqun Shi Guizao Huang Pengli Li Qi Kang Xingyi Huang Guangning Wu | 2022 | Nano Research2022，15，5： | 0 |
