| 1 | Heterogeneous lamellar-edged Fe-Ni(OH)_(2)/Ni_(3)S_(2)nanoarray for efficient and stable seawater oxidation显示文摘Development of efficient non-precious catalysts for seawater electrolysis is of great significance but challenging due to the sluggish kinetics of oxygen evolution reaction(OER)and the impairment of chlorine electrochemistry at anode.Herein,we report a heterostructure of Ni_(3)S_(2)nanoarray with secondary Fe-Ni(OH)_(2)lamellar edges that exposes abundant active sites towards seawater oxidation.The resultant Fe-Ni(OH)_(2)/Ni_(3)S_(2)nanoarray works directly as a free-standing anodic electrode in alkaline artificial seawater.It only requires an overpotential of 269 mV to afford a current density of 10 mA·cm^(-2)and the Tafel slope is as low as 46 m V·dec^(-1).The 27-hour chronopotentiometry operated at high current density of 100 mA·cm^(-2)shows negligible deterioration,suggesting good stability of the Fe-Ni(OH)_(2)/Ni_(3)S_(2)@NF electrode.Faraday efficiency for oxygen evolution is up to〜95%,revealing decent selectivity of the catalyst in saline water.Such desirable catalytic performance could be benefitted from the introduction of Fe activator and the heterostructure that offers massive active and selective sites.The density functional theory(DFT)calculations indicate that the OER has lower theoretical overpotential than Cl_(2) evolution reaction in Fe sites,which is contrary to that of Ni sites.The experimental and theoretical study provides a strong support for the rational design of high-performance Fe-based electrodes for industrial seawater electrolysis. | Baihua Cui Zheng Hu Chang Liu Siliang Liu Fangshuai Chen Shi Hu Jinfeng Zhang Wei Zhou Yida Deng Zhenbo Qin Zhong Wu Yanan Chen Lifeng Cui Wenbin Hu | 2021 | Nano Research2021，14，4： | 7 |
| 2 | Thermal Shock-Activated Spontaneous Growing of Nanosheets for Overall Water Splitting显示文摘Nanomaterials based on nickel foam(NF) have been widely applied in energy conversion and storage field.Traditional synthesis methods such as hydrothermal method which is dangerous and high cost limited the scalable developments.Herein,we report a fast,simple,and low-cost synthesis method of nanomaterials based on NF by Joule-heating and water soaking treatment.Thin carbon-coated CoS on NF(NF-C/CoS) was synthesized by Joule-heating for a few seconds with rapid cooling.And then,NF-C/CoS/NiOOH with core-shell heterostructure was fabricated by soaking treatment of NF-C/CoS in water on which NiOOH nanosheets grew spontaneously.The formation mechanism is proposed that the coordination complex precursor converts into C/CoS on NF driven by Joule-heating,and the nickel on the surface of NF is activated to form metastable nickel simultaneously.The metastable nickel reacting with water leads to the formation of NiOOH,and the induction of CoS makes NiOOH grow continuously.This synthesis technology provides a new route to manufacture NF-based nanostructures,and the as-fabricated NF-C/CoS/NiOOH exhibits great potential as electrocatalyst for oxygen evolution reaction and hydrogen evolution reaction. | Han Wu Qi Lu Jinfeng Zhang Jiajun Wang Xiaopeng Han Naiqin Zhao Wenbin Hu Jiajun Li Yanan Chen Yida Deng | 2020 | Nano-Micro Letters2020，12，11： | 6 |
| 3 | Engineering cobalt sulfide/oxide heterostructure with atomically mixed interfaces for synergistic electrocatalytic water splitting显示文摘It remains challenging to develop economical and bifunctional electrocatalysts toward oxygen/hydrogen evolution reactions(OER/HER).Herein,we construct Co_(9)S_(8) nanoflakes decorated Co_(3)O_(4) nanoarrays with enriched heterogeneous interface zones on Ni foam(Co_(9)S_(8)@CO_(3)O_(4)/NF)via a novel step-wise approach.The Co_(9)S_(8)@Co_(3)O_(4)/NF hybrid manifests excellent performance with low overpotentials of 130 mV for HER(10 mA·cm^(-2))and 331 mV for OER(100 mA·cm^(-2)),delivering a small voltage of 1.52 V for water splitting at 10 mA·cm^(-2) as well as outstanding catalytic durability,which surpasses precious metals and previously reported earth-abundant nanocatalysts.Further experimental and theoretical investigations demonstrate that the excellent performance is attributed to the followings:(i)Highly conductive Ni facilitates the efficient charge transfer;(ii)porous core-shell nanoarchitecture benefits the infiltration and transportation of gases/ions;(iii)heterogeneous interface zones synergistically lower the chemisorption energy of hydrogen/oxygen intermediates.This work will shed light on the controllable synthesis and engineering of heterostructure nanomaterials for clean energy storage and conversion technologies. | Xiaoyang Wang Yu He Xiaopeng Han Jun Zhao Lanlan Li Jinfeng Zhang Cheng Zhong Yida Deng Wenbin Hu | 2022 | Nano Research2022，15，2： | 2 |
| 4 | Neuroprotective effects of willed-movement therapy in a rat model of cerebral ischemia/reperfusion显示文摘The present study established rat models of middle cerebral artery ischemia/reperfusion using the thread method.Rats performed willed-movement(climbing a ladder or wall in a box) when induced by food and water.Results revealed that Longa scores of neurological deficits significantly de-creased in the willed-movement group at 15 days after reperfusion,while expression of glial fibrillary acidic protein,neurotrophic factor-3,and growth-associated protein-43 significantly increased at 7 and 15 days after reperfusion.Results suggested that willed-movement ameliorated neurological deficits by increasing expression of glial fibrillary acidic protein,neurotrophic factor-3,and growth-associated protein-43. | Deren Hou Jianfeng Liu Jinfeng Deng Zhongyang Hu Chao Feng Haixia Zhu | 2011 | Neural Regeneration Research2011，6，35： | 1 |

| 6 | Effect of grain structure on fatigue crack propagation behavior of Al-Cu-Li alloys显示文摘Recrystallization behavior during optimized heat treatments provides a potential to obtain desirable grain structure,which significantly improves the mechanical properties of aluminum alloys.The influence of grain structures on fatigue crack propagation(FCP)behaviors of Al-Cu-Li alloy with hot-rolled(HR)and cold-rolled(CR)was investigated.Subgrain boundaries have a significant impact on small crack growth rates,which is reflected in the pronounced fluctuation of fatigue crack growth of HR specimens after solution treatment.Moreover,the specific cellular structure within grains can improve the deformation capacity of alloys due to their accommodation of plastic deformation,which contributes to the lower fatigue crack growth rates and higher threshold values in HR specimens.The intragranular deflection also decelerates the FCP rate and occurs in these regions of large grain without subgrain boundaries.Recrystallization occurs in the CR specimens,resulting in small anisotropy on the fatigue resistance for the different orientations in the Paris stage due to the recrystallization texture.Fatigue cracks can be deflected and tend to propagate along the grain boundaries when it goes into the grain with a relatively low Schmidt factor value. | Dingding Lu Ben Lin Tianle Liu Sanxi Deng Youjie Guo Jinfeng Li Danyang Liu | 2023 | Journal of Materials Science & Technology2023，，17： | 1 |
| 7 | YTHDF2-mediated regulations bifurcate BHPF-induced programmed cell deaths显示文摘N6-methyladenosine(m^(6)A)is a critical regulator in the fate of RNA,but whether and how m^(6)A executes its functions in different tissues remains largely obscure.Here we report downregulation of a crucial m^(6)A reader,YTHDF2,leading to tissue-specific programmed cell deaths(PCDs)upon fluorene-9-bisphenol(BHPF)exposure.Currently,Bisphenol A(BPA)substitutes are widely used in plastic manufacturing.Interrogating eight common BPA substitutes,we detected BHPF in 14%serum samples of pregnant participants.In a zebrafish model,BHPF caused tissue-specific PCDs triggering cardiac and vascular defects.Mechanistically,BHPF-mediated downregulation of YTHDF2 reduced YTHDF2-facilitated translation of m^(6)A-gch1 for cardiomyocyte ferroptosis,and decreased YTHDF2-mediated m^(6)A-sting1 decay for caudal vein plexus(CVP)apoptosis.The two distinct YTHDF2-mediated m^(6)A regulations and context-dependent co-expression patterns of gch1/ythdf2 and tnfrsf1a/ythdf2 contributed to YTHDF2-mediated tissue-specific PCDs,uncovering a new layer of PCD regulation.Since BHPF/YTHDF2-medaited PCD defects were also observed in mammals,BHPF exposure represents a potential health threat. | Jiebo Lin Guankai Zhan Jinfeng Liu Yasen Maimaitiyiming Zhiping Deng Baohua Li Kunhui Su Jiafeng Chen Siqi Sun Wanlin Zheng Xianghui Yu Feng He Xiaodong Cheng Lingfang Wang Bin Shen Ziqin Yao Xinquan Yang Jian Zhang Wentao He Hengyu Wu Hua Naranmandura Kao-Jung Chang Junxia Min Jun Ma Mikael Björklund Peng-Fei Xu Fudi Wang Chih-Hung Hsu | 2023 | National Science Review2023，10，12： | 0 |
| 8 | Deployment analysis of composite thin-walled lenticular tubes with effect of storage time and temperature显示文摘Composite Thin-walled Lenticular Tube(CTLT)is increasingly utilized in small satellites missions as a lightweight,foldable,and rollable structural material that facilitates the construction of large deployable systems.The CTLT is initially flattened and coiled around a central hub for storage before launch,during which elastic energy is stored as deformation energy,allowing it to be self-deployed on demand for use in orbit.This work presents a comprehensive investigation into the coiling,storage and deployment behaviors of CTLT that wraps around a central hub.A nonlinear explicit dynamic finite element model was developed with both deformable CTLT and rigidbodies mechanisms including the central hub and guide rollers,as well as the complex interactions among them.The coiling mechanics characteristics such as stored strain energy and rotational moment were presented and validated against experimental data in the literature.Then,the dynamic deployment behaviors were analyzed in terms of two different deployment methods,namely,controlled deployment and free deployment.The effect of material property change during storage was also discussed through numerical experiments. | Jinfeng DENG Ning AN Qilong JIA Xiaofei MA | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
| 9 | Digital Simulation of Projective Non-Abelian Anyons with 68 Superconducting Qubits显示文摘Non-Abelian anyons are exotic quasiparticle excitations hosted by certain topological phases of matter.They break the fermion-boson dichotomy and obey non-Abelian braiding statistics:their interchanges yield unitary operations,rather than merely a phase factor,in a space spanned by topologically degenerate wavefunctions.They are the building blocks of topological quantum computing.However,experimental observation of non-Abelian anyons and their characterizing braiding statistics is notoriously challenging and has remained elusive hitherto,in spite of various theoretical proposals.Here,we report an experimental quantum digital simulation of projective non-Abelian anyons and their braiding statistics with up to 68 programmable superconducting qubits arranged on a two-dimensional lattice.By implementing the ground states of the toric-code model with twists through quantum circuits,we demonstrate that twists exchange electric and magnetic charges and behave as a particular type of non-Abelian anyons,i.e.,the Ising anyons.In particular,we show experimentally that these twists follow the fusion rules and non-Abelian braiding statistics of the Ising type,and can be explored to encode topological logical qubits.Furthermore,we demonstrate how to implement both single-and two-qubit logic gates through applying a sequence of elementary Pauli gates on the underlying physical qubits.Our results demonstrate a versatile quantum digital approach for simulating non-Abelian anyons,offering a new lens into the study of such peculiar quasiparticles. | Shibo Xu Zheng-Zhi Sun Ke Wang Liang Xiang Zehang Bao Zitian Zhu Fanhao Shen Zixuan Song Pengfei Zhang Wenhui Ren Xu Zhang Hang Dong Jinfeng Deng Jiachen Chen Yaozu Wu Ziqi Tan Yu Gao Feitong Jin Xuhao Zhu Chuanyu Zhang Ning Wang Yiren Zou Jiarun Zhong Aosai Zhang Weikang Li Wenjie Jiang Li-Wei Yu Yunyan Yao Zhen Wang Hekang Li Qiujiang Guo Chao Song H.Wang Dong-Ling Deng | 2023 | Chinese Physics Letters2023，40，6： | 0 |
| 10 | STUDY ON THE SEPARATION OF PENTOSE AND HEXOSE FROM GLUCOSE YEAST WATER显示文摘D-ribose is a unique, 5-carbon sugar that occurs naturally in all living cells. D-ribose has been used as a staring material for preparation of some certain medicines or just as a new nutraceutical that helps the body naturally restore its energy level. The fermentative processes are the best for their relatively simple series of production steps and relatively cheap starting materials. However, because of the many impurities in glucose yeast water and its dark color, pretreatment and purification must be done to the fluid before D-ribose can be separated. In this paper, separation and purification of D-ribose was carried out using cation exchange resins, of which Ca2+ exchange resin had the best effect. The optimal condition for adsorption is a flow velocity of 0.5BV/h at adsorption temperature of 25℃. The optimal condition for desorption is a flow velocity of 0.5 BV/h at desorption temperature of 80℃. | ZHENG Changcheng ZHANG Jinfeng LU Yan DENG Guocai CHEN Rongti | 2000 | Chinese Journal of Reactive Polymers2000，9，2： | 0 |
| 11 | Distinct BSRs and their implications for natural gas hydrate formation and distribution at the submarine Makran accretionary zone显示文摘To investigate the nature of gas hydrates in the Makran area,new high-resolution geophysical data were acquired between 2018-2019.The data collected comprise multibeam and two-dimensional multi-channel seismic reflection data.The multibeam bathymetry data show East-North-East(ENE)ridges,piggy-back basins,canyon and channel systems,and the morphology of the abyssal plain.Continuous and discontinuous bottom simulating reflectors(BSRs)occur in the piggy-back basins on most of the seismic profiles available.The BSRs cut the dipping layers with strong amplitude and reversed polarity.Discontinuous BSRs indicate a transition along a dipping high-permeable sand layers from gas-rich segment to the gas hydrate-bearing segment and sugge st alternating sediments of fine and relatively coarse grain size.Double BSRs are highly dynamic and attributed to slumps occurring in the study area.The BSRs induced by slumps are located both at deep and shallow depths,responding to the temperature or pressure variation.For the first time,BSRs are observed in the abyssal plain of the Makran area,being associated with anticline structures,which do not show large spatial continuity and are strongly conditioned by structural conditions such as anticlines and fluid migration pathways,including deep fault,gas chimney,and high-permeable sedimentary layer.Our results may help to assess the gas hydrate potential within the piggy-back basins and to determine the most promising target areas.Moreover,results about the abyssal plain BSR may help to locate hydrocarbon reservoirs in the deep ocean. | Bin LIU Waseem Haider SYED Jiangxin CHEN Xiguang DENG Li YANG Leonardo AZEVEDO Minliang DUAN Tingting WU Jinfeng MA Keliang LI | 2021 | Journal of Oceanology and Limnology2021，39，5： | 0 |
| 12 | Prediction and parametric analysis of 3D borehole and total internal thermal resistance of single U-tube borehole heat exchanger for ground source heat pumps显示文摘The borehole and total internal thermal resistance are both significant parameters in evaluating the thermal performance of the ground source heat pump.This study aimed to obtain the accurate correlation of the 3D borehole and total internal thermal resistance(R_(b,3D)and R_(a,3D))and analyze the impacts of parameters on the R_(b,3D)and R_(a,3D).Firstly,eight parameters affecting the R_(b,3D)and R_(a,3D),including the borehole diameter,pipe diameter,pipe-pipe distance,borehole depth,soil thermal conductivity,grout thermal conductivity,pipe thermal conductivity,and fluid velocity inside the pipe,were considered and an L-54 design matrix was generated.Then,the 3D numerical model,coupling with the four-resistance model,was proposed to calculate R_(b,3D)and R_(a,3D)for each case.After that,the response surface methodology was employed to obtain and verify the correlation of R_(b,3D)and R_(a,3D),which were compared with the existing resistance calculation methods.Lastly,analysis of variance was carried out to reveal parameters that have statistically significant impacts on the R_(b,3D)and R_(a,3D).Results show that the rationality and accuracy of the correlation of R_(b,3D)and R_(a,3D)can be verified by the determination coefficient and P value of regression model,as well as the P value of lack-of-fit.The existing resistance calculation methods are more or less inaccurate and the discrepancies in some cases can be up to 86.74%and 111.35%for the borehole and total internal thermal resistance.The pipe and grout thermal conductivity,pipe and borehole diameter,and the pipe-pipe distance can be seen as the significant contributory factors to the variation of R_(b,3D)and R_(a,3D). | Kun Zhou Jinfeng Mao Yong Li Hua Zhang Zhongkai Deng | 2023 | Energy and Built Environment2023，4，2： | 0 |
| 13 | Promoting the charge separation and photoelectrocatalytic water reduction kinetics of Cu_(2)O nanowires via decorating dual-cocatalysts显示文摘Developing high activity and low-cost materials to produce hydrogen by the sustainable way of photoelectrochemical is key to social development.The abundance and inexpensive Cu_(2)O has been received increasing research as its suitable energy level for photocatalytic water reduction.However,the fast charge recombination rate and the sluggish catalytic kinetics are the huge challenges facing the Cu_(2)O photoreduction.Here,the highly reactive Cu_(2)O@C-MoS_(2)photocathode is constructed by depositing dual-cocatalysts of the carbon layer and MoS_(2)nanosheets on Cu_(2)O nanowires to realize efficient water reduction.An impressive carrier concentration of 6.59×10^(23)cm^(-3)is received,which is 2.78 times of the bare Cu_(2)O,resulting in remarkable enhancement in photocurrent density of 3.34 times for the Cu_(2)O@CMoS_(2)photocathode.Moreover,the applied bias photon-to-current conversion efficiency of the bare Cu_(2)O enhanced 4.5 times from 0.16%to 0.72%in the Cu_(2)O@C-MoS_(2)photocathode.The analysis shows that the Cu_(2)O as light absorber,the carbon layer as electron transfer promoter,and MoS_(2)nanosheets as catalytic sites,thus facilitating chrage separation and enhancing catalytic kinetics.This system paves a feasible strategy for designing other photoelectrodes to realize efficient charge separation and high catalytic activity. | Mengmeng Zhang Jiajun Wang Yang Wang Jinfeng Zhang Xiaopeng Han Yanan Chen Yuesheng Wang Zaghib Karim Wenbin Hu Yida Deng | 2021 | Journal of Materials Science & Technology2021，，3： | 0 |
