| 1 | Preparation and cytocompatibility of polylactic acid/hydroxyapatite/graphene oxide nanocomposite fibrous membrane显示文摘A series of polylactic acid (PLA) based nanocomposite fibrous membranes,including neat PLA,PLA/hydroxyapatite (HA) and PLA/HA/graphene oxide (GO),were fabricated via electrospinning method.The morphology and composition were investigated by scanning electron microscopy (SEM),X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) respectively.The thermal stability was determined by thermogravimetric analysis (TGA).To estimate the cytocompatibility of asprepared PLA/HA/GO fibrous membrane,MC3T3-E1 cells were cultured,and the corresponding cell adhesion and differentiation capability were investigated by fluorescence microscopy,SEM and MTT test.The electrospun ternary PLA/HA/GO membrane exhibited three-dimensional fibrous structure with relatively rough surface morphology,which made itself ideal for cell attachment and proliferation in bone tissue regeneration.The fluorescence microscopy,SEM and MTT test confirmed that the PLA/HA/GO nanocomposite fibrous membrane created a proper environment for the seeding and proliferation of MC3T3-E1 cells. | MA HaiBin SU WenXin TAI ZhiXin SUN DongFei YAN XingBin LIU Bin XUE QunJi | 2012 | Chinese Science Bulletin2012，57，23： | 11 |
| 2 | Facile synthesis of Co and Ce dual-doped Ni3S2 nanosheets on Ni foam for enhanced oxygen evolution reaction显示文摘Nano Research volume 13,pages2130–2135(2020)Cite this article 376 Accesses 2 Citations Metrics details Abstract Developing efficient and stable oxygen evolution reaction(OER)electrocatalysts via doping strategy has well-documented for electrochemical water splitting.Herein,a homogeneous structure(denoted as Co/Ce-Ni3S2/NF)composed of Co and Ce dual doped Ni3S2 nanosheets on nickel foam was synthesized by a facile one-step hydrothermal method.Co and Ce dopants are distributed inside the host sulfide,thereby raising the active sites and the electrical conductivity.Besides,the CeOx nanoparticles generated by part of the Ce dopants as a cocatalyst further improve the catalytic activity by adding defective sites and enhancing the electron transfer.As a consequence,the obtained Co/Ce-Ni3S2/NF electrode exhibits better electrocatalytic activity than single Co or Ce doped Ni3S2 and pure Ni3S2,with low overpotential(286 mV)at 20 mA-cm^−2,a small Tafel slope and excellent long-term durability in strong alkaline solution.These results presented here not only offer a novel platform for designing transition metal and lanthanide dual-doped catalysts,but also supply some guidelines for constructing catalysts in other catalytic applications. | Xiaoxia Wu Tong Zhang Jiaxu Wei Pengfei Feng Xingbin Yan Yu Tang | 2020 | Nano Research2020，13，8： | 5 |
| 3 | Effect of surface area and heteroatom of porous carbon materials on electrochemical capacitance in aqueous and organic electrolytes显示文摘A series of porous carbon materials with wide range of specific surface areas and different heteroatom contents had been prepared using polyaniline as carbon precursor and KOH as an activating agent. Effect of surface area and heteroatom of porous carbon materials on specific capacitance was investigated thoroughly in two typical aqueous KOH and organic 1-butyl-3- methylimidazolium tetrafluoroborate/acetonitirle electrolytes. The different trends of capacitance performance were observed in these two electrolytes. Electrochemical analyses suggested that the presence of faradaic interactions on heteroatom-enriched carbon materials in organic environment is less significant than that observed in aqueous electrolytes. Thus, in aqueous electrolyte, a balance between surface area and heteroatom content of activated porous carbon would be found to develop a supercapacitor with high energy density. In organic electrolyte, the capacitance performance of porous carbon is strongly dependent on the surface area. The results may be useful for the design of porous carbon-based supercapacitor with the desired capacitive performance in aqueous and organic electrolytes. | WANG RuTao LANG JunWei YAN XingBin | 2014 | Science China Chemistry2014，57，11： | 4 |
| 4 | An aqueous zinc-ion hybrid super-capacitor for achieving ultrahigh-volumetric energy density显示文摘Zinc-ion hybrid super-capacitors are regarded as promising safe energy storage systems,However,the relatively low volumetric energy density has become the main bottlenecks in practical applications of portable electronic devices,In this work,the zinc-ion hybrid super-capacitor with high volumetric energy density and superb cycle stability had been constructed which employing the high-density threedimensional graphene hydrogel as cathode and Zn foil used as anode in 1 mol/L ZnSO4 electrolyte.Benefiting from the abundant ion transport paths and the abundant active sites for graphene hydrogel with high density and porous structure,the zinc-ion hybrid super-capacitor exhibited an extremely high volumetric energy density of 118.42 Wh/L and a superb power density of 24.00 kW/L,as well as an excellent long cycle life(80% retention after 30,000 cycles at 10 A/g),which was superior to the volumetric energy density of the reported zinc-ion hybrid super-capacitors.This device,based on the fast ion adsorption/deso rption on the capacitor-type graphene cathode and reversible Zn^(2+) plating/stripping on the battery-type Zn anode,which will inspire the development of zinc-ion hybrid super-capacitor in miniaturized devices. | Li Zhang Dandan Wu Gaowei Wang Yongtai Xu Hongxia Li Xingbin Yan | 2021 | Chinese Chemical Letters2021，32，2： | 4 |
| 5 | Rolling up MXene sheets into scrolls to promote their anode performance in lithium-ion batteries显示文摘Although Ti3 C2 MXene sheets have attracted extensive attention in lithium-ion storage techniques,their restacking makes against and even hinders the Li ions diffusion within them,thereby decreasing the capacity as well as rate performance of conventional MXene anode.Here,for the first time,we roll up the Ti3 C2 Tx sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem.Thus,Ti3 C2 Tx scrolls as anode materials in lithium-ion batteries(LIBs)have higher capacity and better rate performance than Ti3 C2 Tx sheets.On the bases of these,high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti3 C2 Tx/Si composite scrolls.The addition of 10%silicon nanoparticles shows the best overall improvement among capacity,rate capability and cyclic stability for Ti3 C2 Tx scrolls. | Jianing Meng Fangfang Zhang Li Zhang Lingyang Liu Jiangtao Chen Bingjun Yang Xingbin Yan | 2020 | Journal of Energy Chemistry2020，29，7： | 4 |

| 8 | All-climate aqueous supercapacitor enabled by a deep eutectic solvent electrolyte based on salt hydrate显示文摘Aqueous supercapacitors(SCs)have received considerable attention owing to the utilization of low-cost,non-flammable,and low-toxicity aqueous electrolytes thus could eliminate the safety and cost concerns,but their wide temperature range applications have generally suffered from frozen of electrolyte and insufficient ionic conductivity at low temperatures.Herein,we demonstrate the feasibility of using an unconventional Deep Eutectic Solvent(DES)based on H2O-Mg(ClO4)2·6 H2O binary system as electrolyte to construct all-climate aqueous carbon-based SC.This unconventional class DES completely base on inorganic substances and achieving simply mix inexpensive salts and water together at the right proportions.Attributed to the attractive feature of extremely low freeze temperature of-69℃,this electrolyte can enable the 1.8 V carbon-based SC to fully work at-40℃with outstanding cycling stability.This DES electrolyte comprising of a single salt and a single solvent without any additive will open up an avenue for developing simple and green electrolytes to construct all-climate SC. | Xudong Bu Yurong Zhang Yinglun Sun Lijun Su Jianing Meng Xionggang Lu Xingbin Yan | 2020 | Journal of Energy Chemistry2020，29，10： | 2 |
| 9 | Monitoring the mechanical properties of the solid electrolyte interphase(SEI)using electrochemical quartz crystal microbalance with dissipation显示文摘Stable solid electrolyte interphase(SEI)has been well established to be critical for the reversible operation of Li(ion)batteries,yet our understanding of its mechanical properties currently remains incomplete.Here,we used an electrochemical quartz crystal microbalance combined with dissipation monitoring(EQCM-D)to investigate SEI formation.By quantitatively estimating in-situ,the change in mass,shear modulus,and viscosity of the SEI,we show that the SEI formation in propylene carbonate(PC)-and ethylene carbonate/diethyl carbonate(EC/DEC)-based electrolytes involves the growth of a rigid laye r followed by a viscoelastic layer,whereas a distinct'one-layer'rigid model is applicable to the SEI formulated in tetraethylene glycol dimethyl ether(TEGDME)-based electrolyte.With the continuous formation of the SEI,its shear modulus decreases accompanied by an increase in viscosity.In TEGDME,the lightest/thinnest SEI(mass lower than in PC by a factor of nine)yet having the greatest stiffness(more than five times that in PC)is obtained.We attribute this behavior to differences in the chemical composition of the SEIs,which have been revealed by tracking the mass-change-per-mole-of-electrontransferred using EQCM-D and further confirmed by X-ray photoelectron spectroscopy. | Yinguang Chai Wenshan Jia Zhiqiu Hu Song Jin Hongchang Jin Huanxin Ju Xingbin Yan Hengxing Ji Li-Jun Wan | 2021 | Chinese Chemical Letters2021，32，3： | 2 |
| 10 | Effect of carboxylic acid groups on the supercapacitive performance of functional carbon frameworks derived from bacterial cellulose显示文摘Three-dimensional(3D) carbonaceous materials derived from bacterial cellulose(BC) has been introduced as electrode for supercapacitors in recent. Here, we report a simple strategy for the synthesis of functional carbon frameworks through 2,2,6,6-tetramethylpilperidine 1-oxyl radical(TEMPO)-mediated oxidation of bacterial cellulose(BC) followed by carbonization. TEMPO-mediated oxidation can efficiently convert the hydroxyls on the surface of BC to carboxylate groups to improve electrochemical activity. Because of its high porosity, good hydrophilicity, rich oxygen groups, and continuous ion transport in-between sheet-like porous network, the TEMPO-oxidized BC delivers a much higher gravimetric capacitance(137.3 F/g) at low annealing temperature of 500℃ than that of pyrolysis BC(31 F/g) at the same annealing temperature. The pyrolysis modified BC obtained at 900℃ shows specific capacitance(160.2 F/g), large current stability and long-term stability(84.2% of its initial capacitance retention after 10,000 cycles). | Tianyun Zhang Junwei Lang Li Liu Lingyang Liu Hongxia Li Yipeng Gu Xingbin Yan Xin Ding | 2017 | Chinese Chemical Letters2017，28，12： | 2 |
| 11 | The roles of graphene in advanced Li-ion hybrid supercapacitors显示文摘Lithium-ion hybrid supercapacitors(LIHSs), also called Li-ion capacitors, are electrochemical energy storage devices that combining the advantages of high power density of supercapacitor and high energy density of Li-ion battery. However, high power density and long cycle life are still challenges for the current LIHSs due to the imbalance of charge-storage capacity and electrode kinetics between capacitor-type cathode and battery-type anode. Therefore, great efforts have been made on designing novel cathode materials with high storage capacity and anode material with enhanced kinetic behavior for LIHSs. With unique two-dimensional form and numerous appealing properties, for the past several years, the rational designed graphene and its composites materials exhibit greatly improved electrochemical performance as cathode or anode for LIHSs. Here, we summarized and discussed the latest advances of the stateof-art graphene-based materials for LIHSs applications. The major roles of graphene are highlighted as(1) a superior active material,(2) ultrathin 2D flexible support to remedy the sluggish reaction of the metal compound anode, and(3) good 2D building blocks for constructing macroscopic 3D porous carbon/graphene hybrids. In addition, some high performance aqueous LIHSs using graphene as electrode were also summarized. Finally, the perspectives and challenges are also proposed for further development of more advanced graphene-based LIHSs. | Junwei Lang Xu Zhang Bao Liu RutaoWang Jiangtao Chen Xingbin Yan | 2018 | Journal of Energy Chemistry2018，27，1： | 2 |

| 15 | High-performance nitrogen and sulfur co-doped nanotube-like carbon anodes for sodium ion hybrid capacitors显示文摘Sodium ion hybrid capacitors are of great concern in large-scale and cost-effective electrical energy storage owing to their high energy and power densities,as well as natural abundance and wide distribution of sodium.However,it is difficult to find a well-pleasing anode material that matches the high-performance cathode materials to achieve good energy and power output for sodium ion hybrid capacitors.In this paper,nitrogen and sulfur co-doped nanotube-like carbon prepared by a simple carbonization process of high sulfur-loaded polyaniline nanotubes is introduced as the anode.The assembled sodium ion half cell based on the optimal nanotube-like carbon delivers a high reversible capacity of ~304.8 mAh/g at 0.2 A/g and an excellent rate performance of ~124.8 mAh/g at 10 A/g in a voltage window of 0.01-2.5 V(versus sodium/sodium ion).For the hybrid capacitors assembled using the optimal nanotube-like carbon as the anode and high-capacity activated carbon as the cathode,high energy densities of ~100.2 Wh/kg at 250 W/kg and ~50.69 Wh/kg at 12,500 W/kg are achieved. | Yongqiang Ding Yali Li Junshuai Li Xingbin Yan | 2020 | Chinese Chemical Letters2020，31，9： | 1 |
