| 1 | Nanotwinned and hierarchical nanotwinned metals:a review of experimental,computational and theoretical efforts显示文摘The recent studies on nanotwinned(NT)and hierarchical nanotwinned(HNT)face-centered cubic(FCC)metals are presented in this review.The HNT structures have been supposed as a kind of novel structure to bring about higher strength/ductility than NT counterparts in crystalline materials.We primarily focus on the recent developments of the experimental,atomistic and theoretical studies on the NT and HNT structures in the metallic materials.Some advanced bottom-up and top-down techniques for the fabrication of NT and HNT structures are introduced.The deformation induced HNT structures are available by virtue of severe plastic deformation(SPD)based techniques while the synthesis of growth HNT structures is so far almost unavailable.In addition,some representative molecular dynamics(MD)studies on the NT and HNT FCC metals unveil that the nanoscale effects such as twin spacing,grain size and plastic anisotropy greatly alter the performance of NT and HNT metals.The HNT structures may initiate unique phenomena in comparison with the NT ones.Furthermore,based on the phenomena and mechanisms revealed by experimental and MD simulation observations,a series of theoretical models have been proposed.They are effective to describe the mechanical behaviors of NT and HNT metals within the applicable scope.So far the development of manufacturing technologies of HNT structures,as well as the studies on the effects of HNT structures on the properties of metals are still in its infancy.Further exploration is required to promote the design of advanced materials. | Ligang Sun Xiaoqiao He Jian Lu | 2018 | npj Computational Materials2018，，1： | 14 |
| 2 | Effects of rare earth elements La and Yb on the morphological and functional development of zebrafish embryos显示文摘In recent years,with the wide applications and mineral exploitation of rare earth elements,their potential environmental and health effects have caused increasing public concern.Effect of rare earth elements La and Yb on the morphological and functional development of zebrafish embryos were studied.The embryos were exposed to La3+ or Yb3+ at 0,0.01,0.1,0.3,0.5 and 1.0 mmol/L,respectively.Early life stage parameters such as egg and embryo mortality,gastrula development,tail detachment,eyes,somite formation,circulatory system,pigmentation,malformations,hatching rate,length of larvae and mortality were investigated.The results showed La3+ and Yb3+ delayed zebrafish embryo and larval development,decreased survival and hatching rates,and caused tail malformation in a concentration-dependent way.Moreover,heavy rare-earth ytterbium led to more severe acute toxicity of zebrafish embryo than light rare-earth lanthanum. | Jun'an Cui Zhiyong Zhang Wei Bai Ligang Zhang Xiao He Yuhui Ma Yan Liu Zhifang Chai | 2012 | Journal of Environmental Sciences2012，24，2： | 8 |
| 3 | Reveal training performance mystery between Tensor Flow and PyTorch in the single GPU environment显示文摘Deep learning has gained tremendous success in various fields while training deep neural networks(DNNs)is very compute-intensive,which results in numerous deep learning frameworks that aim to offer better usability and higher performance to deep learning practitioners.Tensor Flow and Py Torch are the two most popular frameworks.Tensor Flow is more promising within the industry context,while Py Torch is more appealing in academia.However,these two frameworks differ much owing to the opposite design philosophy:static vs dynamic computation graph.Tensor Flow is regarded as being more performance-friendly as it has more opportunities to perform optimizations with the full view of the computation graph.However,there are also claims that Py Torch is faster than Tensor Flow sometimes,which confuses the end-users on the choice between them.In this paper,we carry out the analytical and experimental analysis to unravel the mystery of comparison in training speed on single-GPU between Tensor Flow and Py Torch.To ensure that our investigation is as comprehensive as possible,we carefully select seven popular neural networks,which cover computer vision,speech recognition,and natural language processing(NLP).The contributions of this work are two-fold.First,we conduct the detailed benchmarking experiments on Tensor Flow and Py Torch and analyze the reasons for their performance difference.This work provides the guidance for the end-users to choose between these two frameworks.Second,we identify some key factors that affect the performance,which can direct the end-users to write their models more efficiently. | Hulin DAI Xuan PENG Xuanhua SHI Ligang HE Qian XIONG Hai JIN | 2022 | Science China(Information Sciences)2022，65，1： | 6 |
| 4 | Metallomics in environmental and health related research:Current status and perspectives显示文摘Metals and metalloids play distinct roles in human health,either beneficial or toxic,depending on their concentrations and species.There is an increasing interest in metals uptake,trafficking,function,and exertion in microorganisms to maintain and advance human health.Metallomics,an emerging research area,focuses on elucidation of metals/metalloids location,distribution,speciation,and behavior in living organisms.This paper briefly summarized the recent progress on the methodology development of metallomics including various techniques,i.e.multiple dimensional liquid chromatography-inductively coupled plasma mass spectrometry(LC-ICPMS),gel electrophoresis-laser ablation-inductively coupled plasma mass spectrometry(GE-LA-ICPMS),synchrotron X-ray fluorescent spectroscopy(XFS),and the applications of metallomics in environmental and health care. | HU LiGang HE Bin WANG YuChuan JIANG GuiBin SUN HongZhe | 2013 | Chinese Science Bulletin2013，58，2： | 2 |
| 5 | The PIWI-specific insertion module helps load longer piRNAs for translational activation essential for male fertility显示文摘PIWI-clade proteins harness pi RNAs of 24–33 nt in length.Of great puzzles are how PIWI-clade proteins incorporate pi RNAs of different sizes and whether the size matters to PIWI/pi RNA function.Here we report that a PIWI-Ins module unique in PIWIclade proteins helps define the length of pi RNAs.Deletion of PIWI-Ins in Miwi shifts MIWI to load with shorter pi RNAs and causes spermiogenic failure in mice,demonstrating the functional importance of this regulatory module.Mechanistically,we show that longer pi RNAs provide additional complementarity to target m RNAs,thereby enhancing the assembly of the MIWI/e IF3f/Hu R super-complex for translational activation.Importantly,we identify a c.1108C>T(p.R370W)mutation of HIWI(human PIWIL1)in infertile men and demonstrate in Miwi knock-in mice that this genetic mutation impairs male fertility by altering the property of PIWI-Ins in selecting longer pi RNAs.These findings reveal a critical role of PIWI-Ins-ensured longer pi RNAs in fine-tuning MIWI/pi RNA targeting capacity,proven essential for spermatid development and male fertility. | Xin Wang Di-Hang Lin Yue Yan An-Hui Wang Jiaoyang Liao Qian Meng Wen-Qing Yang Heng Zuo Min-Min Hua Fengjuan Zhang Hongwen Zhu Hu Zhou Tian-Yu Huang Rui He Guangyong Li Yue-Qiu Tan Hui-Juan Shi Lan-Tao Gou Dangsheng Li Ligang Wu Yonggang Zheng Xiang-Dong Fu Jinsong Li Rujuan Liu Guo-Hui Li Mo-Fang Liu | 2023 | Science China(Life Sciences)2023，66，7： | 2 |
| 6 | Electrochemical deposited amorphous FeNi hydroxide electrode for oxygen evolution reaction显示文摘The electrodeposition approach is significant in electrode fabrication for practical application.Herein,the electrodeposited amorphous NiFe hydroxide species for oxygen evolution reaction (OER) in water splitting reaction is demonstrated by revealing the synergistic effect influenced by the support electrode of Fe and Ni foil and the contents of Fe and Ni in the electrolyte.All the electrodeposited samples have an amorphous structure and similar profiles of binding energy and chemical states for Fe and Ni as characterized by the spectroscopic techniques.While the support effect and Fe/Ni synergistic effect are indeed observed for the varied catalytic performances observed for the different electrodes;the Ni foil supported catalyst exhibits much higher performance than that of the Fe foil supported catalyst,and the different redox potentials of Ni species in the different Fe/Ni electrode resulting from the Fe–Ni synergism are observed in the cyclic voltammetry curve analysis.The surface roughness and the electrochemical surface area are also influenced by the support effect and the Fe/Ni ratio in the plating electrolyte.The optimal electrode shows a very low overpotential of~200 mV to reach 10 mA cm^(-2),and very high catalytic stability by the consecutive cyclic voltammetry measurements and 20 h stability test.Though it has the largest electrochemical surface area,the highest catalytic efficiency for these active sites is also indicated by the specific activity and turnover frequency polarization curves.The current work shows the effective experience for the electrodeposited Fe/Ni based catalysts in large-scale fabrication,which can be more practical for hydrogen generation in the alkaline water electrolysis. | Zhengzhi Yin Runze He Yongcai Zhang Ligang Feng Xiang Wu Thomas Wågberg Guangzhi Hu | 2022 | Journal of Energy Chemistry2022，31，6： | 2 |

| 8 | Healthy soils for sustainable food production and environmental quality显示文摘Soil is the foundation for sustainable foodproduction and environmental protection. Created byunsustainable land management practices and a range ofsocial, economic and environmental drivers, soil degrada-tion and pollution have been an ongoing threat tointernational food security and environmental quality.Soil degradation and pollution assessments are, however,often focused on the soil itself with little scope to devisenew soil management approaches that match foodproduction systems and/or environmentalprotection.This study draws lessons from an Australia-China JointResearch Center Program, Healthy Soils for SustainableFood Production and Environmental Quality: a researchplatform that has brought together multi-disciplinaryapproaches fromworld-renowned universitiesandresearch organizations in Australia and China. To thisend, a framework is presented for future soil managementin a new way that combines excellence in research,industry and policymakers in a partnership that will ensurenot only the right focus of the research but also that high-quality outputs will be transferable to industry and end-users. | Xia LIANG Jizheng HE Fusuo ZHANG Qirong SHEN Jinshui WU lain MYOUNG Anthony GO'DONNELL Ligang WANG Enli WANG Julian HILL Deli CHEN | 2020 | Frontiers of Agricultural Science and Engineering2020，7，3： | 1 |

| 12 | Heat-treated glassy carbon under pressure exhibiting superior hardness,strength and elasticity显示文摘Glassy carbon(GC)is a type of non-graphitizing disordered carbon material at ambient pressure and high temperatures,which has been widely used due to its excellent mechanical properties.Here we report the changes in the microstructure and mechanical properties of GC treated at high pressures(up to 5 GPa)and high temperatures.The formation of intermediate sp2-sp3 phases is identified at moderate treatment temperatures before the complete graphitization of GC,by analyzing synchrotron X-ray diffraction,Raman spectra,and transmission electron microscopy images.The intermediate metastable carbon materials exhibit superior mechanical properties with hardness reaching up to 10 GPa and compressive strength reaching as high as 2.5 GPa,nearly doubling those of raw GC,and improving elasticity and thermal stability.The synthesis pressure used in this study can be achieved in the industry on a commercial scale,enabling the scalable synthesis of this type of strong,hard,and elastic carbon materials. | Meng Hu Shuangshuang Zhang Bing Liu Yingju Wu Kun Luo Zihe Li Mengdong Ma Dongli Yu Lingyu Liu Yufei Gao Zhisheng Zhao Yoshio Kono Ligang Bai Guoyin Shen Wentao Hu Yang Zhang Ralf Riedel Bo Xu Julong He Yongjun Tian | 2021 | Journal of Materiomics2021，7，1： | 1 |

| 15 | Super square carbon nanotube network: a new promising water desalination membrane显示文摘Super square(SS)carbon nanotube(CNT)networks,acting as a new kind of nanoporous membrane,manifest excellent water desalination performance.Nanopores in SS CNT network can efficiently filter NaCl from water.The water desalination ability of such nanoporous membranes critically depends on the pore diameter,permitting water molecule permeatration while salt ion obstruction.On the basis of the systematical analysis on the interaction among water permeability,salt concentration limit and pressure on the membranes,an empirical formula is developed to describe the relationship between pressure and concentration limit.In the meantime,the nonlinear relationship between pressure and water permeability is examined.Hence,by controlling pressure,optimal plan can be easily made to efficiently filter the saltwater.Moreover,steered molecular dynamics(MD)method uncovers bending and local buckling of SS CNT network that leads to salt ions passing through membranes.These important mechanical behaviours are neglected in most MD simulations,which may overestimate the filtration ability.Overall,water permeability of such material is several orders of magnitude higher than the conventional reverse osmosis membranes and several times higher than nanoporous graphene membranes.SS CNT networks may act as a new kind of membrane developed for water desalination with excellent filtration ability. | Ligang Sun Xiaoqiao He Jian Lu | 2016 | npj Computational Materials2016，，1： | 1 |
| 16 | Efficient Pt/KFI zeolite catalysts for the selective catalytic reduction of NOxby hydrogen显示文摘Aiming at purification of NO_(x)from hydrogen internal combustion engines(HICEs),the hydrogen selective catalytic reduction(H_(2)-SCR)reaction was investigated over a series of Pt/KFI zeolite catalysts.H_(2)can readily reduce NO_(x)to N_(2)and N_(2)O while O_(2)inhibited the deNO_(x)efficiency by consuming the reductant H_(2).The Pt/KFI zeolite catalysts with Pt loading below 0.1wt.% are optimized H_(2)-SCR catalysts due to its suitable operation temperature window since high Pt loading favors the H_(2)-O_(2)reaction which lead to the insufficient of reactants.Compared to metal Pt^(0)species,Pt^(δ+)species showed lower activation energy of H_(2)-SCR reaction and thought to be as reasonable active sites.Further,Eley-Rideal(E-R)reaction mechanism was proposed as evidenced by the reaction orders in kinetic studies.Last,the optimized reactor was designed with hybrid Pt/KFI catalysts with various Pt loading which achieve a high NO_(x)conversion in a wide temperature range. | Ligang Zhang Yulong Shan Zidi Yan Zhongqi Liu Yunbo Yu Hong He | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 17 | The effect of umbrella-type branching on the blood circulation and tumor targeting of star-branched PLA-PMPC copolymer micelles显示文摘The effect of branching on the blood circulation and tumor targeting of polymer nanovehicles in vivo was investigated in this study. For the purpose, star-branched poly(lactic acid) and poly(2-methacryloyloxyethyl phosphorylcholine)(PLA-PMPC)copolymers with umbrella-type AB3,(AB3)_(2), and(AB3)_(3) architecture were synthesized by branching at the PLA core. Micelles self-assembled from these copolymers were used to evaluate the effect of core branching on blood circulation and tumor targeting. The results showed that branching changed the behavior of polymeric self-assembly in solution, thereby changing the size and surface anti-fouling performance of the polymeric micelles. Moreover, star-branched copolymer micelles with a higher branching degree allowed their payload to persist better in blood(half-time prolonged from 7.1, 8.6 to 13.8 h) and for a 1.72-fold higher content at the tumor site. These studies suggest that raising the branching degree of amphiphilic copolymer potentially offers a promising strategy for the design of carriers capable of enhanced circulation and targeting in vivo. | LONG LiXia CHENG LinJie HOU JingJing WANG LiMei WANG Xu HE LiGang LI SiDi ZHAO Jin HOU Xin KANG ChunSheng YUAN XuBo | 2021 | Science China(Technological Sciences)2021，64，1： | 0 |
| 18 | Amorphous FeCoNi-S as efficient bifunctional electrocatalysts for overall water splitting reaction显示文摘Developing bifunctional electrocatalysts for overall water splitting reaction is still highly desired but with large challenges. Herein, an amorphous Fe Co Ni-S electrocatalyst was developed using thioacetamide for the sulfuration of Fe Co Ni hydroxide during the hydrothermal process. The obtained catalyst exhibited an amorphous structure with hybrid bonds of metal-S bond and metal-O bonds in the catalyst system. The optimized catalyst showed a largely improved bifunctional catalytic ability to drive water splitting reaction in the alkaline electrolyte compared to the Fe Co Ni hydroxide. It required an overpotential of 280 m V and 80 m V(No-IR correction) to offer 10 m A/cm^(2)for water oxidation and reduction respectively;a low cell voltage of 1.55 V was required to reach 10 m A/cm^(2)for the water electrolysis with good stability for12 h. Moreover, this catalyst system showed high catalytic stability, catalytic kinetics, and Faraday efficiency for water splitting reactions. Considering the very low intrinsic activity of Fe Co Ni hydroxide, the efficient bifunctional catalytic ability should result from the newly formed hybrid active sites of metallic metal-S species and the high valence state of metal oxide species. This work is effective in the bifunctional catalytic ability boosting for the transition metal materials by facile sulfuration in the hydrothermal approach. | Runze He Chunyan Wang Ligang Feng | 2023 | Chinese Chemical Letters2023，34，2： | 0 |

| 20 | Au nanoclusters anchored on TiO_(2) nanosheets for high-efficiency electroreduction of nitrate to ammonia显示文摘Electrocatalytic nitrate reduction reaction(NO_(3)RR)offers a unique rationale for green NH_(3) synthesis,yet the lack of high-efficiency NO_(3)RR catalysts remains a great challenge.In this work,we show that Au nanoclusters anchored on TiO_(2) nanosheets can efficiently catalyze the conversion of NO_(3)RR-to-NH_(3) under ambient conditions,achieving a maximal Faradic efficiency of 91%,a peak yield rate of 1923μg·h^(-1)·mgcat.-1,and high durability over 10 consecutive cycles,all of which are comparable to the recently reported metrics(including transition metal and noble metal-based catalysts)and exceed those of pristine TiO_(2).Moreover,a galvanic Zn-nitrate battery using the catalyst as the cathode was proposed,which shows a power density of 3.62 mW·cm^(-2) and a yield rate of 452μg·h^(-1)·mgcat.-1.Theoretical simulations further indicate that the atomically dispersed Au clusters can promote the adsorption and activation of NO_(3)-species,and reduce the NO_(3)RR-to-NH_(3) barrier,thus leading to an accelerated cathodic reaction.This work highlights the importance of metal clusters for the NH_(3) electrosynthesis and nitrate removal. | Miaosen Yang Tianran Wei Jia He Qian Liu Ligang Feng Hongyi Li Jun Luo Xijun Liu | 2024 | Nano Research2024，17，3： | 0 |
