| 1 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020，13，9： | 14 |
| 2 | Recent advances in the improvement of g-C_(3)N_(4) based photocatalytic materials显示文摘g-C_(3)N_(4) have been widely used in the fields of photocatalytic hydrogen production,photocatalytic degradation of dyes and oxidative degradation of toxic gases due to their excellent performance.It has attracted extensive attention in recent years due to its highly efficient photocatalytic capacity of hydrogen generation,water oxidation,carbon dioxide reduction and degradation of organic pollutants.Because of the abundant carbon and nitrogen composition of the earth,large-scale production and industrial applications of this material are possible.The modification of this material makes its performance more excellent so that this new material can obtain a steady stream of vitality.These outstanding works have become important materials and milestones on the road to mankind's photocatalytic hydrogen production.This review will begin with the basic idea of designing,synthesizing and improving g-C_(3)N_(4) based photocatalytic materials,and introduce the latest development of g-C_(3)N_(4) photocatalysts in hydrogen production from four aspects of controlling the carbon/nitrogen ratio,morphology,element doping and heterojunction structure of g-C_(3)N_(4) materials. | Yupeng Xing Xiaoke Wang Shuhua Hao Xueli Zhang Xiao Wang Wenxuan Ma Gang Zhao Xijin Xu | 2021 | Chinese Chemical Letters2021，32，1： | 10 |
| 3 | Electrochemical performance of Ti_(3)C_(2)supercapacitors in KOH electrolyte显示文摘Two-dimensional(2D)carbide Ti_(3)C_(2)was synthesized by exfoliating Ti_(3)AlC_(2)in HF solution and used for supercapacitive performance investigation in 3 M KOH electrolyte.The specific surface area(SSA)of as-synthesized Ti_(3)C_(2)was 22.35 m^(2)/g.Ti_(3)C_(2)-based supercapacitor electrodes exhibited good energy storage ability and had a volumetric capacitance 119.8 F/cm^(3)at the current density of 2.5 A/g.Moreover,the addition of carbon black into Ti_(3)C_(2)powders greatly improved the performance of Ti_(3)C_(2)-based capacitors because carbon black restrained the preferred orientation of 2D Ti_(3)C_(2),providing fast ion transport channels,and in turn,decreasing electrical resistance from 16.7Ωto 3.5Ω. | Yupeng GAO Libo WANG Zhengyang LI Yafei ZHANG Baolin XING Chuanxiang ZHANG Aiguo ZHOU | 2015 | Journal of Advanced Ceramics2015，4，2： | 10 |
| 4 | Why the hydrothermal fluorinated method can improve photocatalytic activity of carbon nitride显示文摘Carbon nitride(CN) photocatalysts have attracted much attention due to their excellent photocatalytic properties.And hydrothermal fluorination is a common method to improve the photocatalytic effect of CN photocatalyst.Here,the influence of the band gap was first revealed of fluorination and hydroxylation of CN photocatalyst based on the first theoretical principle.Here,the effect of fluorination and hydroxylation on the CN band gap was discussed for the first time using the first theoretical principle.With F atoms and OH doping,the band gap of CN was significantly improved,conduction band and valence band moved up.Then,F-CN photocatalyst with F atoms and OH was successfully synthesized by a hydrothermal fluorinated method.Next,the reasons why F-CN photocatalyst was more effective than that of traditional CN photocatalyst were fully discussed.From the photocatalytic effect of photocatalyst(12,593.2 μmolg^(-1) h^(-1)to the morphology(super-small nanosheets),structure(homojunctions),composition(metal-free),specific surface area(54.1 m^(2)/g),visible light absorption response(AQE is10.9% at 420 nm) and photo-induced carrier life(14.13 ns).Therefore,this work has a great guiding effect on the development of CN photocatalyst. | Gang Zhao Yupeng Xing Shuhua Hao Xijin Xu Wenxuan Ma Jinghua Guo | 2021 | Chinese Chemical Letters2021，32，1： | 1 |
| 5 | Probing the dynamic structural changes of DNA using ultrafast laser pulse in graphene-based optofluidic device显示文摘The ultrafast monitoring of deoxyribonucleic acid(DNA)dynamic structural changes is an emerging and rapidly growing research topic in biotechnology.The existing optical spectroscopy used to identify different dynamical DNA structures lacks quick response while requiring large consumption of samples and bulky instrumental facilities.It is highly demanded to develop an ultrafast technique that monitors DNA structural changes with the external stimulus or cancer-related disease scenarios.Here,we demonstrate a novel photonic integrated graphene-optofluidic device to monitor DNA structural changes with the ultrafast response time.Our approach is featured with an effective and straightforward design of decoding the electronic structure change of graphene induced by its interactions with DNAs in different conformations using ultrafast nanosecond pulse laser and achieving refractive index sensitivity of~3×10^(−5) RIU.This innovative technique for the first time allows us to perform ultrafast monitoring of the conformational changes of special DNA molecules structures,including G-quadruplex formation by K+ions and i-motif formation by the low pH stimulus.The graphene-optofluidic device as presented here provides a new class of label-free,ultrafast,ultrasensitive,compact,and cost-effective optical biosensors for medical and healthcare applications. | Bannur NShivananju Lu Zhou Yuefeng Yin Wenzhi Yu Babar Shabbir Haoran Mu Xiaozhi Bao Yiqiu Zhang Sun Tian Qingdong Ou Shaojuan Li Mohammad MHossain Yupeng Zhang Huaiyu Shao Guichuan Xing Nikhil V.Medhekar Chang-Ming Li Jian Liu Qiaoliang Bao | 2021 | InfoMat2021，3，3： | 1 |
| 6 | Mo-doped one-dimensional needle-like Ni_(3)S_(2) as bifunctional electrocatalyst for efficient alkaline hydrogen evolution and overall-water-splitting显示文摘Hydrogen energy plays an important role in clean energy system and is considered the core energy source for future technological development owing to its lightweight nature,high calorific value,and clean combustion products.The electrocatalytic conversion of water into hydrogen is considered a highly promising method.An electrocatalyst is indispensable in the electrocatalytic process,and finding an efficient electrocatalyst is essential.However,the current commercial electrocatalysts(such as Pt/C and Ru)are expensive;therefore,there is a need to find an inexpensive and efficient electrocatalyst with high stability,corrosion resistance,and high electrocatalytic efficiency.In this study,we developed a cost-effective bifunctional electrocatalyst by incorporating molybdenum into nickel sulfide(Ni_(3)S_(2))and subsequently tailoring its structure to achieve a one-dimensional(1D)needle-like configuration.The hydrogen production efficiency of nickel sulfide was improved by changing the ratio of Mo doping.By analyzing the electrochemical performance of different Mo-doped catalysts,we found that the Ni_(3)S_(2)-Mo-0.1 electrocatalyst exhibited the best electrocatalytic effect in 1 M KOH;at a current density of 10 mA cm^(-2),it exhibited overpotentials of 120 and 279 mV for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER),respectively;at a higher current density of 100 mA cm^(-2),the HER and OER overpotentials were 396 and 495 mV,respectively.Furthermore,this electrocatalyst can be used in a two-electrode water-splitting system.Finally,we thoroughly investigated the mechanism of the overall water splitting of this electrocatalyst,providing valuable insights for future hydrogen production via overall-water-splitting. | Junjie Huang Yupeng Xing Jinzhao Huang Fei Li Gang Zhao Xingmin Yu Binxun Li Xinran Zhang | 2024 | ChemPhysMater2024，3，1： | 0 |
| 7 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 8 | Smart nanocarriers as therapeutic platforms for bladder cancer显示文摘Although patients benefit from surgical transurethral resection of bladder cancers,some niduses are missed or incompletely resected,and small malignant lesions may recur.Intravesical chemotherapy and immunotherapy are universally accepted as adjuvant treatments after surgery to avoid recurrence and progression.However,these treatments still have limitations,including an insufficient retention period,inefficient permeability of chemotherapeutic agents,and dilution of the agents by urine.Nanostructure-based smart therapeutic platforms can be tailored to be responsive to internal or external stimuli to ameliorate this situation.This unparalleled capability empowers the precise aggregation of stimulus–responsive nanocarriers in the target regions,namely,the tumors,and subsequent release of the anticancer materials.This review summarizes the current nanostructure-based therapeutic platforms,especially stimulus–responsive nanocarriers,and highlights their benefits and limitations in bladder cancer therapy.Novel innovations in nanotechnology have undoubtedly arrived at a new height and have become useful for practical applications.Nanotechnology will positively promote the development of anticancer agents not only for bladder cancer but also for other solid tumors. | Tongyu Tong Yupeng Guan Yuanji Gao Chengyuan Xing Shiqiang Zhang Donggen Jiang Xiangwei Yang Yang Kang Jun Pang | 2022 | Nano Research2022，15，3： | 0 |
| 9 | High Order Finite Difference Hermite WENO Fixed-Point Fast Sweeping Method for Static Hamilton-Jacobi Equations显示文摘In this paper, we combine the nonlinear HWENO reconstruction in [43] andthe fixed-point iteration with Gauss-Seidel fast sweeping strategy, to solve the staticHamilton-Jacobi equations in a novel HWENO framework recently developed in [22].The proposed HWENO frameworks enjoys several advantages. First, compared withthe traditional HWENO framework, the proposed methods do not need to introduceadditional auxiliary equations to update the derivatives of the unknown function φ.They are now computed from the current value of φ and the previous spatial derivatives of φ. This approach saves the computational storage and CPU time, which greatlyimproves the computational efficiency of the traditional HWENO scheme. In addition,compared with the traditional WENO method, reconstruction stencil of the HWENOmethods becomes more compact, their boundary treatment is simpler, and the numerical errors are smaller on the same mesh. Second, the fixed-point fast sweeping methodis used to update the numerical approximation. It is an explicit method and doesnot involve the inverse operation of nonlinear Hamiltonian, therefore any HamiltonJacobi equations with complex Hamiltonian can be solved easily. It also resolves someknown issues, including that the iterative number is very sensitive to the parameterε used in the nonlinear weights, as observed in previous studies. Finally, to furtherreduce the computational cost, a hybrid strategy is also presented. Extensive numerical experiments are performed on two-dimensional problems, which demonstrate thegood performance of the proposed fixed-point fast sweeping HWENO methods. | Yupeng Ren Yulong Xing Jianxian Qiu | 2022 | Communications in Computational Physics2022，31，1： | 0 |
| 10 | Exploring the growth mechanism of CuSbSe_(2)thin film prepared by electrodeposition显示文摘Copper antimony selenium(CuSbSe_(2))has advantages of adjustable band gaps from 1.09 eV to 1.2 eV,high light absorption coefficient(>105 cm-1),and low grain generation temperature(300—400℃),which is suitable for the preparation of solar cells.However,the stable range of CuSbSe_(2)(CASe)phase is narrow,which is inevitable to form Sb_(2)Se_(3)and Cu_(3)SbSe_(4)second phase during the preparation process.In this work,selenization annealing of Sb/Cu metal layer to prepare CASe thin films with pulse electrodeposition process was studied,and the growth mechanism of CASe film was analyzed.Cu and Sb reacted with Se to form Cu_(2)Se and Sb_(2)Se_(3),respectively.Then Cu_(2)Se and Sb_(2)Se_(3)further reacted to generate CASe.Since the formation temperature of Cu_(3)SbSe_(4)was lower than that of CASe,the preferential formation of Cu_(3)SbSe_(4)led to layer separation.When the annealing temperature was too high,CASe decomposed to form Cu_(3)SbSe_(3)and Sb_(2)Se_(3).Additionally,by increasing the heating rate,the separation of CASe thin films was effectively improved,and the CASe thin films with relatively high crystallinity were obtained at 360℃with heating rate of 30℃/min and selenization time of 20 min. | WANG Ruihu BI Jinlian LI Wei YUAN Yujie XING Yupeng YAO Liyong | 2023 | Optoelectronics Letters2023，19，9： | 0 |
| 11 | Analysis of effects of front and back surface dopants on silicon vertical multi-junction solar cell by 2D numerical simulation显示文摘The silicon vertical multi-junction(VMJ)solar cell has a good potential in high concentration,but it requires high quality front and back surface passivation layers to keep its high efficiency.We try to add dopants into the front and back surfaces of the VMJ cell to release this strict requirement in this work.The effects of recombination velocities,doping types and doping profiles of front and back surfaces on the performance of the P-type VMJ cell were calculated under 1 sun and 1000 suns.The 2D numerical simulation tool TCAD software was used.The performance of the VMJ cell without front and back surface dopants was also calculated for comparison.It was found that the requirement of high quality front and back surface passivation layers could be released remarkably by adding either N-type or P+-type front and back surface dopants.For the two types of front surface dopants,the highest efficiencies of the cells were got by light dopant;for the two types of back surface dopants,the doping type and profile affected little on the performance of the cell in our calculation range.It was also found that the series resistance of the VMJ cell with N-type front surface dopant was decreased by the 2D effect of front surface emitter.The VMJ cell with P+-type front surface dopant had the highest efficiency under 1000 suns and the VMJ cell with N-type front surface dopant had the highest efficiency under 1 sun in our calculation range. | XING YuPeng HAN PeiDe WANG Shuai LIANG Peng LOU ShiShu ZHANG YuanBo HU ShaoXu ZHU HuiShi MI YanHong ZHAO ChunHua | 2013 | Science China(Technological Sciences)2013，56，11： | 0 |
| 12 | In Situ Observation of Silt Seabed Pore Pressure Response to Waves in the Subaqueous Yellow River Delta显示文摘The in situ pore pressure response of silt under wave action is a complex process.However,this process has not been well studied because of limited field observation techniques.The dynamic response process is closely related to engineering geological hazards;thus,this process must be urgently explored.A long-term in situ observational study of the silt sediment pore water pressure response process under wave action was conducted in the subaqueous Yellow River Delta.The response characteristics of pore water pressure are affected by tidal level and wave height.Tidal level affects the overall trend of the pore water pressure response,while wave height influences the amplitude of the pore water pressure response.This study revealed a significant lag effect in the pore pressure response.The transient pore pressure in the seabed did not respond immediately to the wave-induced pressure stress on the seabed surface.This phenomenon may be attributed to the change in soil permeability.The maximum response depth was approximately 0.5 m with a 2 m wave height.A concept model of silt soil pore pressure response under different types of wave action was developed.The accumulation rate of the pore pressure is less than the dissipation rate;thus,the developed model highlights the oscillation pore pres-sure response mechanism.The highlighted response process is of considerable importance to transient liquefaction and the startup process of pore pressure response. | SONG Yupeng SUN Yongfu WANG Zhenhao DU Xing SONG Binghui DONG Lifeng | 2022 | Journal of Ocean University of China2022，21，5： | 0 |
| 13 | HIGH ORDER FINITE DIFFERENCE HERMITE WENO FAST SWEEPING METHODS FOR STATIC HAMILTON-JACOBI EQUATIONS显示文摘In this paper,we propose a novel Hermite weighted essentially non-oscillatory(HWENO)fast sweeping method to solve the static Hamilton-Jacobi equations efficiently.During the HWENO reconstruction procedure,the proposed method is built upon a new finite difference fifth order HWENO scheme involving one big stencil and two small stencils.However,one major novelty and difference from the traditional HWENO framework lies in the fact that,we do not need to introduce and solve any additional equations to update the derivatives of the unknown functionϕ.Instead,we use the currentϕand the old spatial derivative ofϕto update them.The traditional HWENO fast sweeping method is also introduced in this paper for comparison,where additional equations governing the spatial derivatives ofϕare introduced.The novel HWENO fast sweeping methods are shown to yield great savings in computational time,which improves the computational efficiency of the traditional HWENO scheme.In addition,a hybrid strategy is also introduced to further reduce computational costs.Extensive numerical experiments are provided to validate the accuracy and efficiency of the proposed approaches. | Yupeng Ren Yulong Xing Jianxian Qiu | 2023 | Journal of Computational Mathematics2023，41，6： | 0 |
| 14 | Amorphous nickel borate nanosheets as cathode material with high capacity and better cycling performance for zinc ion battery显示文摘Zinc-ion batteries are under current research focus because of their uniqueness in low cost and high safety.However,the pursuing of high-performance cathode materials of aqueous Zinc ion batteries(AZBs)with low cost,high energy density and long cycle life has become the key problem to be solved.Herein we synthesized a series of amorphous nickel borate(AM-NiBO)nanosheets by varying corrosion time with in-situ electrochemical corrosion method.The AM-NiBO-T13 as electrode material possesses a high areal capacity of 0.65 m Ah/cm^(2) with the capacity retention of 95.1%after 2000 cycles.In addition,the assembled AM-NiBO-T13//Zn provides high energy density(0.77 m Wh/cm^(2) at 1.76 m W/cm^(2)).The high areal capacity and better cycling performance can be owing to the amorphous nanosheets structure and the stable coordination characteristics of boron and oxygen in borate materials.It shows that amorphous nickel borate nanosheets have great prospects in the field of energy storage. | Na Li Xixi Zhang Shunshun Zhao Chuanlin Li Xiaojuan Li Tongkai Wang Yupeng Xing Gangmeng Qu Xijin Xu | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 15 | Rational construction of phosphate layer to optimize Cu-regulated Fe_(3)O_(4) as anode material with promoted energy storage performance for rechargeable Ni-Fe batteries显示文摘Flexible aqueous energy storage devices with high security and flexibility are crucial for the progress of wearable energy storage.Particularly,aqueous rechargeable Ni-Fe batteries owning a large theoretical capacity,low cost and outstanding safety characteristics have emerged as a promising candidate for flexible aqueous energy storage devices.Herein,Cu-doped Fe_(3)O_(4)(CFO)with 3D coral structure was prepared by doping Cu^(2+) based on Fe_(3)O_(4)nanosheets(FO).Furthermore,the Fe-based anode material(CFPO)grown on carbon fibers was obtained by reconstructing the surface of CFO to form a low-crystallization shell which can enhance the ion transport.Excitingly,the newly developed CFPO electrode as an innovative anode material further exhibited a high capacity of 117.5 mAh g^(-1)(or 423 F g^(-1))at 1 A g^(-1).Then,the assembled aqueous Ni-Fe batteries with a high cell-voltage output of 1.6 V deliver a high capacity of 49.02 mAh g^(-1) at 1 A g^(-1) and retention ratio of 96.8%for capacitance after 10000 continuous cycles.What’s more,the aqueous quasi-solid-state batteries present a remarkable maximal energy density of 45.6 Wh kg^(-1) and a power density of 12 kW kg^(-1).This work provides an innovative and feasible way and optimization idea for the design of high-performance Fe-based anodes,and may promote the development of a new generation of flexible aqueous Ni-Fe batteries. | Shuhua Hao Yupeng Xing Peiyu Hou Gang Zhao Jinzhao Huang Shipeng Qiu Xijin Xu | 2022 | Journal of Materials Science & Technology2022，，13： | 0 |
| 16 | Interfacial coupling of sea urchin-like(Mo4O11-MoS2-VO_(2)) promoted electron redistributions for significantly boosted hydrogen evolution reaction显示文摘Developing efficient electrocatalysts for hydrogen evolution reaction(HER) is of great importance in contemporary water electrolysis technology. Here, a novel hierarchically sea urchin-like electrocatalyst(Mo_(4)O_(11)-MoS_(2)-VO_(2)) is synthesized by hydrothermal deposition and post-annealing strategy. The optimized electrocatalyst behaves as a high active hydrogen evolution electrode in 0.5 mol/L H_(2)SO_(4). This electrode needs overpotential of only 43 m V to achieve 10 m A/cm^(2)with a Tafel slope of 37 m V/dec and maintains its catalytic activity for at least 36 h. Better than most previously reported non-noble metal electrocatalysts anchored on carbon cloth. It is worth mentioning that the hierarchical sea urchin-like structure promotes the redistribution of electrons and provides more catalytic active sites. This strategy shows a way for the construction of inexpensive non-noble metal electrocatalysts in the future. | Yupeng Xing Na Li Shipeng Qiu Gang Zhao Shuhua Hao Baojie Zhang | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
