| 1 | Reversible Al^(3+) storage mechanism in anatase TiO_(2) cathode material for ionic liquid electrolyte-based aluminum-ion batteries显示文摘Rechargeable aluminum ion battery(AIB) with high theoretical specific capacity, abundant elements and low cost engages considerable attention as a promising next generation energy storage and conversion system. Nevertheless, to date, one of the major barriers to pursuit better AIB is the limited applicable cathode materials with the ability to store aluminum highly reversibly. Herein, a highly reversible AIB is proposed using mesoporous TiO2 microparticles(M-TiO2) as the cathode material. The improved performance of Ti O2/Al battery is ascribed to the high ionic conductivity and material stability, which is caused by the stable architecture with a mesoporous microstructure and no random aggregation of secondary particles. In addition, we conducted detailed characterization to gain deeper understanding of the Al^(3+) storage mechanism in anatase Ti O2 for AIB. Our findings demonstrate clearly that Al^(3+)can be reversibly stored in anatase TiO2 by intercalation reactions based on ionic liquid electrolyte. Especially, DFT calculations were used to investigate the accurate insertion sites of aluminum ions in M-Ti O2 and the volume changes of M-TiO2 cells during discharging. As for the controversial side reactions in AIBs, in this work, by normalized calculation, we confirm that M-Ti O2 alone participate in the redox reaction. Moreover, cyclic voltammetry(CV) test was performed to investigate the pseudocapacitive behavior. | Na Zhu Feng Wu Zhaohua Wang Liming Ling Haoyi Yang Yaning Gao Shuainan Guo liumin Suo Hong Li Huajie Xu Ying Bai Chuan Wu | 2020 | Journal of Energy Chemistry2020，29，12： | 3 |
| 2 | Cobalt-doped Mn3O4 nanocrystals embedded in graphene nanosheets as a high-performance bifunctional oxygen electrocatalyst for rechargeable Zn–Air batteries显示文摘A non-noble-metal bifunctional catalyst with efficient and durable activity towards both the oxygen reduction reaction(ORR)and the oxygen evolution reaction(OER)is crucial to the development of rechargeable Zn-air batteries.Herein,a facile one-step hydrothermal method is reported for the synthesis of a high-performance bifunctional oxygen electrocatalyst,cobalt-doped Mn_(3)O_(4) nanocrystals supported on graphene nanosheets(Co–Mn_(3)O_(4)/G).Compare to pristine Mn_(3)O_(4),this Co–Mn_(3)O_(4)/G exhibits greatly enhanced electrocatalytic activity,delivering a halfwave potential of 0.866 V for the ORR and a low overpotential of 275 mV at 10 mA cm^(-2) for the OER.The zinc-air battery built with Co–Mn_(3)O_(4)/G shows a reduced charge–discharge voltage of 0.91 V at 10 mA cm^(-2),an power density of 115.24 mW cm^(-2) and excellent stability without any degradation after 945 cycles(315 h),outperforming the state-of-the-art Pt/C–Ir/C catalyst-based device. | Mengyang Dong Xu Liu Lixue Jiang Zhengju Zhu Yajie Shu Shan Chen Yuhai Dou Porun Liu Huajie Yin Huijun Zhao | 2020 | Green Energy & Environment2020，5，4： | 2 |

| 4 | Few-shot electromagnetic signal classification:A data union augmentation method显示文摘Deep learning has been fully verified and accepted in the field of electromagnetic signal classification. However, in many specific scenarios, such as radio resource management for aircraft communications, labeled data are difficult to obtain, which makes the best deep learning methods at present seem almost powerless, because these methods need a large amount of labeled data for training. When the training dataset is small, it is highly possible to fall into overfitting, which causes performance degradation of the deep neural network. For few-shot electromagnetic signal classification, data augmentation is one of the most intuitive countermeasures. In this work, a generative adversarial network based on the data augmentation method is proposed to achieve better classification performance for electromagnetic signals. Based on the similarity principle, a screening mechanism is established to obtain high-quality generated signals. Then, a data union augmentation algorithm is designed by introducing spatiotemporally flipped shapes of the signal. To verify the effectiveness of the proposed data augmentation algorithm, experiments are conducted on the RADIOML 2016.04C dataset and real-world ACARS dataset. The experimental results show that the proposed method significantly improves the performance of few-shot electromagnetic signal classification. | Huaji ZHOU Jing BAI Yiran WANG Licheng JIAO Shilian ZHENG Weiguo SHEN Jie XU Xiaoniu YANG | 2022 | Chinese Journal of Aeronautics2022，35，9： | 1 |

| 6 | Microstructure engineering beyond SnSe_(1-x)S_(x)solid solution for high thermoelectric performance显示文摘Recently,SnSe has attracted wide attention as a promising environment-friendly IV-VI thermoelectric material.Here,SnS is alloyed with Na-doped SnSe to decrease the thermal conductivity for better thermoelectric performance.Consistent with previous reports,the lattice constant and the band gap change linearly with increasing SnS,suggesting the formation of SnSe1-xSx solid solution.However,SnS nano-precipitations have been clearly observed,indicating the phase separation in the alloys.Moreover,the grain size decreases obviously with increasing SnS amount.The first-principles calculations show that the nano-precipitation is due to the positive formation energies for SnSe1-xSx in the small x region.Due to the structure engineering,the lattice thermal conductivity is greatly reduced in SnSe1-xSx samples,leading to a promising ZT of 1.35 for Na_(0.03)Sn_(0.97)Se_(0.7S0.3)at 816 K. | Miaomiao Li Hezhu Shao Jingtao Xu Qingsong Wu Xiaojian Tan Guoqiang Liu Min Jin Haoyang Hu Huajie Huang Jianfeng Zhang Jun Jiang | 2018 | Journal of Materiomics2018，4，4： | 1 |

| 8 | Layout Optimization for Greenhouse WSN Based on Path Loss Analysis显示文摘When wireless sensor networks (WSN) are deployed in the vegetablegreenhouse with dynamic connectivity and interference environment, it is necessary to increase the node transmit power to ensure the communication quality,which leads to serious network interference. To offset the negative impact, thetransmit power of other nodes must also be increased. The result is that the network becomes worse and worse, and node energy is wasted a lot. Taking intoaccount the irregular connection range in the cucumber greenhouse WSN, wemeasured the transmission characteristics of wireless signals under the 2.4 Ghzoperating frequency. For improving network layout in the greenhouse, a semiempirical prediction model of signal loss is then studied based on the measureddata. Compared with other models, the average relative error of this semi-empiricalsignal loss model is only 2.3%. Finally, by combining the improved networktopology algorithm and tabu search, this paper studies a greenhouse WSN layoutthat can reduce path loss, save energy, and ensure communication quality. Giventhe limitation of node-degree constraint in traditional network layout algorithms,the improved algorithm applies the forwarding constraint to balance network energyconsumption and constructs asymmetric network communication links. Experimentalresults show that this research can realize the energy consumption optimization ofWSN layout in the greenhouse. | Huarui Wu Huaji Zhu Xiao Han Wei Xu | 2021 | Computer Systems Science & Engineering2021，37，4： | 0 |

| 10 | Development of a High-Temperature Thixotropic Cement Slurry System显示文摘Cementing carbonate reservoirs is generally a difficult task.The so-called thixotropic cement slurry has gained considerable attention in this regard as it can help tofix some notable problems.More precisely,it can easilyfill the leakage layer;moreover,its gelling strength can grow rapidly when pumping stops,thereby increasing the resistance to gas channeling,effectively preventing this undesired phenomenon in many cases.High-temperature thixotropic cement slurry systems,however,are still in an early stage of development and additional research is needed to make them a viable option.In the present study,using a self-developed composite high-temperature thixotropic additive as a basis,it is shown that the compressive strength can be adjusted by tuning the proportion of silica sand,the high-temperature retarder,fluid loss additive and dispersant(compatible with the thixotropic additive).According to the tests,the developed high-temperature thixotropic cement slurry system has a 14 d compressive strength of 29.73 MPa at 150°C,and a thickening time of 330 min when the dosage of retarder is 2%.At the same time,the rheological property,water loss,permeability,water separation rate,and settlement stability of the cement slurry system meet the requirements of cementing construction. | Ping Lv Jiufei Liu Mengran Xu Hui Tian Huajie Liu Yuhuan Bu Zhuang Cai Junfeng Qu | 2023 | Fluid Dynamics & Materials Processing2023，19，11： | 0 |
| 11 | Microstructural Characterization of the Shear Bands in Fe-Cr-Ni Single Crystal by EBSD显示文摘An investigation has been made into the microstructural characterization of the shear bands generated under high-strain rate (≈10~4 s^(-1)) deformation in Fe-15%Cr-15%Ni single crystal by EBSD-SEM (electron backscat- ter diffraction-scanning electron microscopy),TEM (transmission electron in microscopy) and HREM (high- resolution electron microscopy).The results reveal that the propagation of the shear band exhibits an asymmet- rical behavior arising from inhomogenous distribution in plasticity in the bands because of different resistance to the collapse in different crystallographic directions;Theγ-ω-α′phase transformations may take place inside and outside the bands,and these martensitic phases currently nucleate at intersections either between the twins and deformation bands or between the twins andε-sheet.Investigation by EBSD shows that recrystallization can occur in the bands with a grain size of an average of 0.2μm in diameter.These nano-grains are proposed to attribute to the results of either dynamic or static recrystallization,which can be described by the rotational recrystallization mechanism.Calculation and analysis indicate that the strain rate inside the shear band can reach 2.50×10~6 s^(-1),which is higher,by two or three orders of magnitude,than that exerted dynamically on the specimen tested. | Huajie YANG J.H.Zhang Yongbo XU Marc Andre' Meyers | 2008 | Journal of Materials Science & Technology2008，24，6： | 0 |

| 13 | Assessment of the Performances of Carboxylic Acid Monomers as Fluid Loss Additives for Oil-Well Cement显示文摘The application of polycarboxylic acid as a fluid loss additive for cement(i.e.,a substance specifically designed to lower the volume of filtrate that passes through the cement)can prolong the thickening time of cement slurries.Given the lack of data about the effects of carboxylic acid monomers as possible components for the additives traditionally used for oil-well cement,in this study different cases are experimentally investigated considering different types of these substances,concentrations,temperatures,and magnesium ion contamination.The results demonstrate that itaconic acid has a strong retarding side effect,while maleic and acrylic acids have similar influences on the thickening time of the cement slurry.The rheological properties of the cement slurry tend to deteriorate when the carboxylic acid monomer content in the fluid loss additive is increased to 40%.If the temperature exceeds 80°C,there is a significant decrease in the related impact on the thickening duration.With an increase in the intrusion of magnesium ions to>0.5%,both the rheological properties of the cement slurry and the thickening time are affected in a negative way. | Hexing Liu Yi Huang Jinlong Zheng Ye Tian Mengran Xu Huajie Liu | 2022 | Fluid Dynamics & Materials Processing2022，18，4： | 0 |

| 16 | Monoclinic Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O nanobelts/reduced graphene oxide:A novel high-capacity and long-life composite for potassium-ion battery anodes显示文摘Developing suitable anode materials for potassium-ion batteries(PIBs)remains a great challenge owing to the limited theoretical capacity of active materials and large radius of K+ion(1.38?).To solve these obstacles,by integrating the principles of multielectron transfer and rational porous crystal framework,we creatively propose the monoclinic Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O(CVO)as a novel anode for PIBs.Furthermore,inspired by the metastable nature of CVO under high temperature/pressure,we skillfully design a facile hydrothermal recrystallization strategy without the phase change and surfactants addition.Thus,for the first time,the porous composite of Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O nanobelts covered in situ by reduced graphene oxide(CVO NBs/r GO)was assembled,greatly improving the deficiencies of CVO.When used as a novel anode for PIBs,CVO NBs/r GO delivers large specific capacity(up to 551.4 m Ah g^(-1)at 50 m A g^(-1)),high-rate capability(215.3 m Ah g^(-1)at 2.5 A g^(-1))and super durability(203.6 m Ah g^(-1)at 500 m A g^(-1)even after 1000 cycles).The outstanding performance can be ascribed to the synergistic merits of desirable structural features of monoclinic CVO nanobelts and the highly conductive graphene 3D network,thus promoting the composite material stability and electrical/ionic conductivity.This work reveals a novel metal vanadate-based anode material for PIBs,would further motivate the subsequent batteries research on M_(3)(OH)_(2)V_(2)O_(7)-n H_(2)O(M;Co,Ni,Cu,Zn),and ultimately expands valuable fundamental understanding on designing other high-performance electrode materials,including the combined strategies of multielectron transfer with rational porous crystal framework,and the composite fabrication of 1D electrode nanostructure with conductive carbon matrix. | Liming Ling Xiwen Wang Yu Li Chenxiao Lin Dong Xie Min Zhang Yan Zhang Jinjia Wei Huajie Xu Faliang Cheng Chuan Wu Shiguo Zhang | 2022 | Journal of Energy Chemistry2022，31，3： | 0 |
| 17 | High-precision standard enthalpy of formation for polycyclic aromatic hydrocarbons predicting from general connectivity based hierarchy with discrete correction of atomization energy显示文摘The standard enthalpy of formation is an important predictor of the reaction heat of a chemical reaction.In this work,a high-precision method was developed to calculate accurate standard enthalpies of formation for polycyclic aromatic hydrocarbons based on the general connectivity based hierarchy(CBH)with the discrete correction of atomization energy.Through a comparison with available experimental findings and other high-precision computational results,it was found that the present method can give a good description of enthalpy of formation for polycyclic aromatic hydrocarbons.Since CBH schemes can broaden the scope of application,this method can be used to investigate the energetic properties of larger polycyclic aromatic hydrocarbons to achieve a high-precision calculation at the CCSD(T)/CBS level.In addition,the energetic properties of CBH fragments can be accurately calculated and integrated into a database for future use,which will increase computational efficiency.We hope this work can give new insights into the energetic properties of larger systems. | Zihan Xu Huajie Xu Lu Liu Rongpei Jiang Haisheng Ren Xiangyuan Li | 2022 | Frontiers of Chemical Science and Engineering2022，16，12： | 0 |
| 18 | Cross Sections of Barium Isotopes in Interaction of 60 MeV/u ^(18)O with Natural Uranium显示文摘The reactions induced by heavy ions lower than 10 MeV/u have been studied widely. Their reaction mechanism has been also understood in more detail. The contribution to the reaction cross sections in the low energy reactions comes mainly from complex nuclei and deep inelastic process. Early studies mainly focused on the nuclear collisions of low and high energies. In the recent years, great attention has been paid on the intermediate energy heavy ion collisions. Among them measurements of the cross sections and recoiling properties for the target fragmentation products have been applied widely to study the mechanism of the nuclear reactions induced by the intermediate energy heavy ions. But there are a few papers on raodioehemieal studies in the intermediate energy region up to now. | Yang Weifan, Xu Yanbing, Yuan Shuanggui, Niu Yanning, Ting Huajie and Xiao Yonghou | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |
| 19 | Genomic convergence underlying high-altitude adaptation in alpine plants显示文摘Evolutionary convergence is one of the most striking examples of adaptation driven by natural selection.However, genomic evidence for convergent adaptation to extreme environments remains scarce.Here, we assembled reference genomes of two alpine plants, Saussurea obvallata(Asteraceae)and Rheum alexandrae(Polygonaceae), with 37,938 and 61,463 annotated protein-coding genes. By integrating an additional five alpine genomes,we elucidated genomic convergence underlying high-altitude adaptation in alpine plants. Our results detected convergent contractions of diseaseresistance genes in alpine genomes, which might be an energy-saving strategy for surviving in hostile environments with only a few pathogens present.We identified signatures of positive selection on a set of genes involved in reproduction and respiration(e.g., MMD1, NBS1, and HPR), and revealed signatures of molecular convergence on genes involved in self-incompatibility, cell wall modification,DNA repair and stress resistance, which may underlie adaptation to extreme cold, high ultraviolet radiation and hypoxia environments. Incorporating transcriptomic data, we further demonstrated that genes associated with cuticular wax and flavonoid biosynthetic pathways exhibit higher expression levels in leafy bracts, shedding light on the genetic mechanisms of the adaptive “greenhouse” morphology. Our integrative data provide novel insights into convergent evolution at a high-taxonomic level,aiding in a deep understanding of genetic adaptation to complex environments. | Xu Zhang Tianhui Kuang Wenlin Dong Zhihao Qian Huajie Zhang Jacob BLandis Tao Feng Lijuan Li Yanxia Sun Jinling Huang Tao Deng Hengchang Wang Hang Sun | 2023 | Journal of Integrative Plant Biology2023，65，7： | 0 |
