| 1 | Microstructures of metallic film and diamond growth from Fe-Ni-C system显示文摘The microstructures of metallic film surrounding diamond have been systemically studied using the transmission electron microscopy (TEM) and the atom force microscopy (AFM). The film can be divided into three layers (inner layer near diamond, external layer near graphite and middle layer). The graphite cannot be directly transformed into diamond in the film at HTHP: there exists a parallelrelationship between (111) of γ-(Fe,Ni) and (110) of Fe3C in the inner layer; the sawtooth-like step morphology found by AFM on the film is similar to that of corresponding diamond surface. A new model for diamond growth at HPHT is proposed from the parallel relationship and sawtooth-like step morphology. It is believed that Fe3C may be a transitional phase in the course of diamond growth, γ-(Fe,Ni) in the inner layer can absorb carbon atom groups with lamella structure from Fe3C, and then the carbon groups stack on growing diamond. | XU Bin LI Musen YIN Longwei CUI Jianjun LIU Yuxian GONG Jianhong | 2002 | Chinese Science Bulletin2002，47，15： | 12 |
| 2 | CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance. | Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding | 2019 | Science Bulletin2019，64，20： | 2 |

| 5 | A high-performance potassium-ion capacitor based on a porous carbon cathode originated from the Aldol reaction product显示文摘Potassium-ion capacitors(KICs) emerge as a promising substitute for the well-developed lithium-ion capacitors(LICs),however,the energy density of KICs is below expectations because of lacking a suitable electrical double-layer positive electrode.Using chemical activation of the Aldol reaction product of acetone with KOH,we synthesized a porous ca rbon with a Brunauer-Emmett-Teller surface area of up to 2947 m2/g and a narrow pore size distribution ranging from 1 nm to 3 nm.Half-cell(versus potassium metal) test demonstrates that this porous carbon has high capacitive performance in K+ based organic electrolytes.Furthermore,a novel KIC fabricated by this porous carbon as the cathode,yields high values of energy density and power density.The processes used to make this porous carbon are readily low-cost to fabricate metal-ion capacitors. | Xu Yu Mingjie Shao Xuemei Yang Chongxing Li Tong Li Danyu Li Rutao Wang Longwei Yin | 2020 | Chinese Chemical Letters2020，31，9： | 1 |

| 7 | Influence of Heating Rate on Double Reversible Transformation in CuZnAlMnNi Shape Memory Alloy显示文摘The influence of heating rate on double reversible transformation in CuZnAlMnNi shape memory alloy was investigated by differential scanning calorimetry. It was found that rapid heating inhibits X-M transformation but is fa- vorable to the reverse medensite transformation, giving rise to the approach of the two transformation peaks. With the decrease of heating rate, the two transformation peaks separate gradually. | Yujun Bai, Chengwei Lu, Xiangang Xu, Guili Geng, Longwei Yin (Mechanical Department, Shandong University of Science and Technology, Jinan 250031, China Institute of Materials Science and Engineering, Shandong University, Jinan 250061, China) | 2001 | Rare Metals2001，20，2： | 1 |
| 8 | Structural Imperfections Associated with Supersaturated Vacancies in an HPHT-Grown Diamond Single Crystal显示文摘A diamond single crystal, which was synthesized at a high temperature of 1570 K and a high pressure of 5.5 GPa in a Fe-Ni-C system, was directly and systematically examined by transmission electron microscopy (TEM). It is proposed that there exists a variety of imperfections such as dislocation loops, stacking faults, twins and stacking-fault tetrahedral in the diamond, which may be derived from the supersaturated vacancies generated during rapid cooling from high temperature. The formation process of the imperfections is discussed briefly. | Longwei YIN, Musen LI, Dongsheng SUN, Zhangying YAO and Jianjun CUI School of Materials Science and Engineering, Shandong University, Jinan 250061, China Zhaoyin HAO StateKey Laboratory for Superhard Materials, Jilin University, Changchun 130012, China | 2001 | Journal of Materials Science & Technology2001，17，5： | 1 |

| 11 | Scalable synthesis of macroscopic porous carbon sheet anode for potassium-ion capacitor显示文摘Carbon materials hold the great promise for application in energy storage devices owing to their low cost, high thermal/chemical stability, and high electrical conductivity. However, it remains challenging to synthesize high-performance carbon electrodes in a simple, scalable and sustainable way. Here, we report a facile method for scalable synthesis of porous carbon anode by using cheap and easily accessible zeolitic imidazolate framework-8 as a template and polyvinylpyrrolidone as an additional carbon source. The obtained porous carbon shows the macroscopic sheet-like morphology, which has the highly disordered structure, expanded interlayer spacing, abundant pore structure, and nitrogen doping properties. This porous carbon anode is demonstrated to have the excellent K^(+) charge storage properties in specific capacity, rate capability, and cycling stability. A potassium-ion capacitor assembled by using this porous carbon as the anode, delivers a maximum energy density of 85.12 Wh/kg and power density of 11860 W/kg as well as long cycle life exceeding 3000 cycles. This represents a critical advance in the design of low cost and scalable carbon material for applications in energy storage devices. | Yuying Qin Yuhao Xie Han Zhao Chunyan Zhu Tong Li Shuxian Zhang Rutao Wang Yuanchang Shi Longwei Yin | 2022 | Chinese Chemical Letters2022，33，3： | 1 |

| 19 | Electrocatalytic hydrogen evolution performance of modified Ti_(3)C_(2)O_(2)doped with non-metal elements:A DFT study显示文摘Developing highly conductive,stable,and active hydrogen evolution reaction(HER)catalysts is a critical step towards establishing the hydrogen economy.However,there are few catalysts,except for noble metals,that can meet all the requirements.Recently,two-dimensional(2D)transition metal carbon/nitride(MXene)materials have shown excellent performance in catalysis,and have attracted wide attention from researchers.In this study,the effectiveness of non-metal element(B,C,N,P,and S)-doped Ti_(3)C_(2)O_(2)MXene in the electrocatalytic hydrogen evolution reaction was investigated using density functional theory(DFT)calculations.Non-metal atoms as elec-tron donors can provide additional electrons to the O functional group on the catalyst surface,thereby reducing charge transfer from H to O and the interaction between H and O.The Gibbs free energy(ΔG H)of non-metal element-doped Ti_(3)C_(2)O_(2)is closer to 0 than that of pristine Ti_(3)C_(2)O_(2),demonstrating better hydrogen evolution performance.Furthermore,in the hydrogen evolution path,the desorption process is more inclined to the Hey-rovsky mechanism,and doping greatly reduces the energy barrier of the reaction,thereby improving the catalytic efficiency.The present results prove that doping with non-metallic elements is an effective means of improving the catalytic activity of Ti_(3)C_(2)O_(2)for hydrogen evolution. | Zhongxiao Wang Haoxiang Di Rui Sun Yuting Zhu Longwei Yin Zhiwei Zhang Chengxiang Wang | 2022 | ChemPhysMater2022，1，4： | 0 |
| 20 | Advanced all-solid-state lithium-selenium batteries enabled by selenium-nitrogen doped hierarchic meso-microporous carbon nanospheres composite cathode显示文摘Selenium,an element belonging to the same group in the periodic table as sulfur,has a high electronic conductivity(1×10^(-5)S/cm)and a high volumetric energy density(3253 mA h/cm^(3)),which is a prospective cathode material for high-energy all-solid-state rechargeable batteries.However,its wide use is hindered by large volume expansion and low utilization rate.In this work,Se-infused nitrogen-doped hierarchical meso-microporous carbon composites(Se/NHPC)are prepared by a melt-diffusion process.Amorphous Se is uniformly dispersed in meso-micropores of NHPC with a high mass loading of 81%.All-solid-state Li-Se batteries fabricated by using Se/NHPC as the cathode,a Li-In alloy as the anode,and Li_(6)PS_(5)Cl as the solid-state electrolyte,deliver a highly reversible capacity of 621 m Ah/g(92%of theoretical capacity),a good rate capability and a high capacity retention value of 80.9%after 100 cycles.It is found that the capacity decay of Se cathode is mainly related to the interfacial degradation and the separation of Se from the carbon substrate,as suggested by the continuous increase of interfacial resistance and the structural transformation from amorphous Senchains to Se8rings initial discharge/charge cycle and then to the trigonally crystalline Se chains structure after the long-term cycles. | Chongxing Li Renbo Liu Shuxian Zhang Qingyu Li Cong Wang Zhiwei Zhang Chengxiang Wang Longwei Yin Rutao Wang | 2023 | Chinese Chemical Letters2023，34，9： | 0 |
