| 1 | Microbial aerosol chemistry characteristics in highly polluted air显示文摘Aerosol chemistry is often studied without considering microbial involvements. Here, we investigated time-and size-resolved bacterial aerosol dynamics in air. Under high particulate matter(PM) polluted episodes, bacterial aerosols exhibited a viability of up to 50%–70% in the 0.56–1 μm size range, at which elevated levels of SO42-, NO3- and NH4+ were concurrently observed.Engineered or acclimated for both industrial use, bacteria such as Psychrobacter spp., Massilia spp., Acinetobacter lwoffii,Exiguobacteriumaurantiacum and Bacillusmegaterium were shown to have experienced massive abundance shifts in polluted air on early mornings and late afternoons, on which rapid new particle formation events were widely reported. Here, Psychrobacter spp. were shown to account for >96% abundance at a corresponding PM2.5 level of 208 μg/m3. These observed bacterial aerosol changes corresponded to the PM2.5 mass peak shift from 3.2–5.6 μm to the high viability size range of 0.56–1 μm. Additionally,elevated levels of soluble Na, Ca, Mg, K, Al, Fe and P elements, required for bacterial growth, were observed to co-occur with those significant bacterial aerosol structure shifts in the air. For particular time-resolved PM2.5 pollution episodes, Acinetobacter,Psychrobacter and Massilia were shown to alternate in dominating the time-resolved aerosol community structures. The results from a HYSPLIT trajectory model simulation suggested that air mass transport played a minor role in affecting the observed bacterial aerosol structure dynamics. All the data here suggested that airborne bacteria in the size range of 0.56–1 μm could be extensively involved in aerosol chemistry in highly polluted humid air. | Ting Zhang Xinyue Li Minfei Wang Haoxuan Chen Maosheng Yao | 2019 | Science China Chemistry2019，62，8： | 8 |
| 2 | Proteomic Analysis of Macrophages:A Potential Way to Identify Novel Proteins Associated with Activation of Macrophages for Tumor Cell Killing显示文摘One major mechanism through which macrophages effectively kill tumor cells requires cell to cell contact,indicating that certain molecules expressed on cell surface of activated macrophages may mediate the tumoricidal capability. Tumor necrosis factor (TNF) and nitric oxide (NO) are the two classical mediators of tumor cell death. However,evidence of discrepancy is accumulating indicating these known mediators do not appear to account for the broad and potent tumoricidal activity of macrophages. To obtain a full repertoire of tumoricidal activation-associated membrane proteins,we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique,we identified 454 activated macrophage specifically expressed proteins with extremely high confidence,including most known activation markers of macrophages,such as NO synthase (iNOS),Ym1,cyclooxygenase,etc. Membrane bound TNF-α was also identified on activated macrophages. However,it was also detected on thioglycolate elicited macrophages,indicating this molecule may not play a key role in conjugation-dependent tumor cell killing. In contrast,although NO has not been assigned as an effector molecule of conjugation-dependent tumoricidal pathway,iNOS was identified from membrane fraction of activated macrophages,suggesting NO may be involved in conjugation-dependent tumoricidal mechanism,because iNOS association with plasma membrane is ideally suited to deliver NO directly into the contacted tumor cells. This research provides not only new insights into macrophage conjugation-dependent tumoricidal mechanisms,but also a valuable data set of macrophage activation associated membrane proteins,thus providing better understanding of the functional mechanisms of macrophages in anti-tumor and other biological processes. | Lingbing Zhang Haoxuan Zhu Yanni Lun Dongmei Yan Leyang Yu Bairong Du Xun Zhu | 2007 | Cellular & Molecular Immunology2007，4，5： | 7 |
| 3 | Synthesis,biological activities and 3D-QSAR studies of(R)-2-phenyl-4,5-dihydrothiazole-4-carboxamide derivatives containing a sulfur ether moiety显示文摘A series of(R)-2-phenyl-4,5-dihydrothiazole-4-carboxamide derivatives containing a sulfur ether moiety were synthesized and characterized on the basis of NMR and elemental analysis(EA). The crystal structure of(R)-N-(2-methyl-1-(methylthio)propan-2-yl)-2-(4-nitrophenyl)-4,5-dihydrothiazole-4-carboxamide(13 d) was determined to show R configuration. The bioasssy results indicated that most title compounds displayed good and broad spectrum antifungal activities against several phytopathogenic fungi. The structure activity relationships were discussed. Based on the antifungal activity of title compounds against Phytophthora capsici, a CoMSIA calculation was performed to establish a 3 D-QSAR model, which revealed that electrostatic and hydrophobic fields were the two most significant factors for antifungal activity. According to the established 3D-QSAR model, structure optimization was carried out to find(R)-N-((R)-1-(methylthio)propan-2-yl)-2-(p-tolyl)-4,5-dihydrothiazole-4-carboxamide(15 h)with excellent activity against Phytophthora capsici, thus emerging as a new lead compound for novel antiphytopathogenic fungus agent development. | Jingbo Liu Fengyun Li Yuanhong Wang Haoxuan Zhang Jingyue Dong Pengwei Sun Yuxin Li Zhengming Li | 2019 | Chinese Chemical Letters2019，30，3： | 5 |
| 4 | A water-evaporation-induced self-charging hybrid power unit for application in the Internet of Things显示文摘A self-charging hybrid power unit has been developed by integrating a water-evaporation-induced nano- generator with a flexible nano-patterned supercapacitor. The nanogenerator can harvest environmental thermal energy and mechanical energy through the water evaporation process, and the supercapacitor can be charged simultaneously. The former offers stable electrical power as output, whereas the Ppy- based supercapacitor shows a capacitance of 12.497 m F/cm^2 with 96.42% retention after 4,000 cycles. After filling the power unit with water as the fuel, it can be fully charged in about 20 min. The power unit can be flexibly integrated with electronic devices such as sensor nodes and wireless transmitters employ- ing the Internet of Things. This new approach can offer new possibilities in continuous future operation of randomly distributed electronic devices incorporated in the Internet of Things. | Haoxuan He Tianming Zhao Hongye Guan Tianyan Zhong Hui Zeng Lili Xing Yan Zhang Xinyu Xue | 2019 | Science Bulletin2019，64，19： | 5 |
| 5 | Numerical simulation of dam-break flow and bed change considering the vegetation effects显示文摘Existing numerical investigations of dam-break flows rarely consider the effects of vegetation.This paper presents a depth-averaged two-dimensional model for dam-break flows over mobile and vegetated beds.In the model,both the consequences of reducing space for storing mass and momentum by the existence of vegetation and dragging the flow are considered:the former is considered by introducing a factor(1-c) to the flow depth,where c is the vegetation density;the later is considered by including an additional sink term in the momentum equations.The new governing equations are discretized by the finite volume method;and an existing second-order central-upwind scheme embedded with the hydrostatic reconstruction method for water depth,is used to estimate the fluxes;the source terms are estimated by either explicit or semi-explicit methods fulfilling the stability requirement.Laboratory experiments of dam-break flows or quasi-steady flows with/without vegetation effects/sediment transport are simulated.The good agreements between the measurements and the numerical simulations demonstrate a satisfactory performance of the model in reproducing the flow depth,velocity and bed deformation depth.Numerical case studies of six scenarios of dam-break flows over a mobile and vegetated bed are conducted.It is shown that when the area of the vegetation zone,the vegetation density,and the pattern of the vegetation distribution are varied,the resulted bed morphological change differs greatly,suggesting a great influence of vegetation on the dam-break flow evolution.Specifically,the vegetation may divert the direction of the main flow,hindering the flow and thus result in increased deposition upstream of the vegetation. | Zhiguo He Ting Wu Haoxuan Weng Peng Hu Gangfeng Wu | 2017 | International Journal of Sediment Research2017，32，1： | 5 |
| 6 | Low-dimensional nanomaterial/Si heterostructure-based photodetectors显示文摘Due to its excellent electrical and optical features,silicon(Si)is highly attractive for photodetector applications.The design and fabrication of low-dimensional semiconductor/Si hybrid heterostructures provide a great platform for fabricating high-performance photodetectors,thereby overcoming the inherent limitations of Si.This review focuses on state-of-the-art Si heterostructure-based photodetectors.It starts with the introduction of three different device configurations,that is,photoconductors,photodiodes,and phototransistors.Their working mechanisms and relative pros and cons are introduced,and the figures of merit of photodetectors are summarized.Then,we discuss the device physics/design,photodetection performance,and optimization strategies for Si-based photodetectors.Finally,future challenges in the photodetector applications of Si-based hybrid heterostructures are discussed. | Wei Tian Haoxuan Sun Liang Chen Peihua Wangyang Xinrui Chen Jie Xiong Liang Li | 2019 | InfoMat2019，1，2： | 5 |
| 7 | A Teosinte-derived Allele of a MYB Transcription Repressor Confers Multiple Disease Resistance in Maize.显示文摘Natural alleles controlling multiple disease resistances (MDR) are valuable for crop breeding. However, only one MDR gene have been cloned in maize, and molecular mechanisms of MDR are not clear. By map-based cloning, we have cloned a teosinte-derived allele of a resistance gene, Mexicana lesion mimic 1 (ZmMM1), which has a lesion mimic phenotype and confers resistance to northern leaf blight (NLB), gray leaf spot (GLS) and southern corn rust (SCR). Strong MDR conferred by the teosinte allele is linked with the polymorphisms in the 3' untranslated region of the ZmMM1 gene that cause increased accumulation of ZmMM1 protein. ZmMM1 acts as a transcription repressor and negatively regulates transcription of specific target genes including ZmMM1-target gene 3 (ZmMT3), which functions as a negative regulator of plant immunity and associated cell death. The successful isolation of the ZmMM1 resistance gene will help not only in developing broad-spectrum and durable disease resistance but also in understanding the molecular mechanisms underlying MDR. | Hongze Wang Jiabao Hou Pei Ye Long Hu Junshi Huang Zhikang Dai Bao Zhang Sha Dai Jiamin Que Haoxuan Min Gengshen Chen Yanbo Wang Min Jiang Yan Liang Lin Li Xuecai Zhang Zhibing Lai | 2021 | Molecular Plant2021，14，11： | 4 |
| 8 | A Self-Powered Breath Analyzer Based on PANI/PVDF Piezo-Gas-Sensing Arrays for Potential Diagnostics Application显示文摘The increasing morbidity of internal diseases poses serious threats to human health and quality of life.Exhaled breath analysis is a noninvasive and convenient diagnostic method to improve the cure rate of patients. In this study, a self-powered breath analyzer based on polyaniline/polyvinylidene fluoride(PANI/PVDF) piezogas-sensing arrays has been developed for potential detection of several internal diseases. The device works by converting exhaled breath energy into piezoelectric gassensing signals without any external power sources. The five sensing units in the device have different sensitivities to various gas markers with concentrations ranging from 0 to 600 ppm. The working principle can be attributed to the coupling of the in-pipe gas-flow-induced piezoelectric effect of PVDF and gas-sensing properties of PANI electrodes. In addition, the device demonstrates its use as an ethanol analyzer to roughly mimic fatty liver diagnosis.This new approach can be applied to fabricating new exhaled breath analyzers and promoting the development of self-powered systems. | Yongming Fu Haoxuan He Tianming Zhao Yitong Dai Wuxiao Han Jie Ma Lili Xing Yan Zhang Xinyu Xue | 2018 | Nano-Micro Letters2018，10，4： | 4 |
| 9 | Comparing containment measures among nations by epidemiological effects of COVID-19显示文摘The coronavirus disease 2019(COVID-19)has evolved to a global pandemic since its inception in December 2019.Countries have responded to the epidemics with different levels of responses and containment measures.Given the unprecedented pressure on nations’healthcare systems and the deaths so far,there is an urgent need to evaluate the effects of the containm ent measures,which would be useful for countries to plan for their responses to counter the first or possibly the second wave of the epidemic.There have been studies for the effects of COVID-19 control measures taken in China on disease transmission and public health interventions for W uhan’s outbreaks[1-4],and W uhan travel ban on the spread of COVID-19 both inside China and internationally[5,6]. | Jia Gu Han Yan Yaxuan Huang Yuru Zhu Haoxuan Sun Yumou Qiu Songxi Chen | 2020 | National Science Review2020，7，12： | 4 |
| 10 | Energy-Optimal Braking Control Using a Double-Layer Scheme for Trajectory Planning and Tracking of Connected Electric Vehicles显示文摘Most researches focus on the regenerative braking system design in vehicle components control and braking torque distribution,few combine the connected vehicle technologies into braking velocity planning.If the braking intention is accessed by the vehicle-to-everything communication,the electric vehicles(EVs)could plan the braking velocity for recovering more vehicle kinetic energy.Therefore,this paper presents an energy-optimal braking strategy(EOBS)to improve the energy efficiency of EVs with the consideration of shared braking intention.First,a double-layer control scheme is formulated.In the upper-layer,an energy-optimal braking problem with accessed braking intention is formulated and solved by the distance-based dynamic programming algorithm,which could derive the energy-optimal braking trajectory.In the lower-layer,the nonlinear time-varying vehicle longitudinal dynamics is transformed to the linear time-varying system,then an efficient model predictive controller is designed and solved by quadratic programming algorithm to track the original energy-optimal braking trajectory while ensuring braking comfort and safety.Several simulations are conducted by jointing MATLAB and CarSim,the results demonstrated the proposed EOBS achieves prominent regeneration energy improvement than the regular constant deceleration braking strategy.Finally,the energy-optimal braking mechanism of EVs is investigated based on the analysis of braking deceleration,battery charging power,and motor efficiency,which could be a guide to real-time control. | Haoxuan Dong Weichao Zhuang Guodong Yin Liwei Xu Yan Wang Fa’an Wang Yanbo Lu | 2021 | Chinese Journal of Mechanical Engineering2021，34，5： | 3 |
| 11 | Highly surface electron-deficient Co_(9)S_(8) nanoarrays for enhanced oxygen evolution显示文摘Tailoring valence electron delocalization of transition metal center is of importance to achieve highly-active electrocatalysts for oxygen evolution reaction(OER).Herein,we demonstrate a“poor sulfur”route to synthesize surface electron-deficient Co_(9)S_(8) nanoarrays,where the binding energy(BE)of Co metal center is considerably higher than all reported Co_(9)S_(8)-based electrocatalysts.The resulting Co_(9)S_(8) electrocatalysts only require the overpotentials(h)of 265 and 326 mV at 10 and 100 mA cm^(-2) with a low Tafel slope of 56 mV dec^-(1) and a 60 hlasting stability in alkaline media.The OER kinetics are greatly expedited with a low reaction activation energy of 27.9 kJ mol^-(1) as well as abundant OOH*key intermediates(24%),thus exhibiting excellent catalytic performances.The surface electron-deficient engineering gives an available strategy to improve the catalytic activity of other advanced non-noble electrocatalysts. | Haoxuan Zhang Jingyu Wang Qilin Cheng Petr Saha Hao Jiang | 2020 | Green Energy & Environment2020，5，4： | 3 |
| 12 | Semiempirical equations of state of H_(2)O/CO_(2) binary mixtures in graphite nanoslits显示文摘The existence of confining walls limits the prediction accuracy of nanoconfined fluids using macroscopic equations of state(EOSs);moreover,appropriate EOSs for multicomponent mixture fluids in nanoconfined spaces are missing.Here,we derive the EOS of multicomponent mixture fluids confined in nanospaces at high temperatures and pressures,mainly considering the nanoconfinement effect and the competitive adsorption effect between different components.Then,the EOSs are validated through comparison with the molecular dynamics-simulated Pv T data of CO_(2)/H_(2)O mixtures in graphite nanoslits.To consider the above effects,we derive two EOSs via two modeling methods:EOS I is obtained through modification of the actual component occupation volume in the Peng-Robinson equation of state(PR EOS)by fitting the binary component interaction coefficient and the number of adsorbed molecules according to a selectivity coefficient,while EOS II is obtained by considering the decreased pressure of the fluids in PR EOS by adding an attractive term between components and walls.With the simulation results as a benchmark,the two EOSs exhibited good prediction accuracies under low CO_(2) concentrations,and generally,EOS II was more accurate than EOS I.This study fills the gap in the EOSs of nanoconfined mixture fluids,and the obtained equations can help to further describe the thermodynamic properties of confined mixture fluids. | Haoxuan Li Bin Zhao Chengzhen Sun Bofeng Bai | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 2 |
| 13 | Oxidation behaviors of(Hf_(0.25)Zr_(0.25)Ta_(0.25)Nb_(0.25))C and(Hf_(0.25)Zr_(0.25)Ta_(0.25)Nb_(0.25))C-SiC at 1300-1500℃显示文摘In this work,high-entropy ceramics(Hf_(0.25) Zr_(0.25)Ta_(0.25)Nb_(0.25))C(HZTNC) and HZTNC doped with 20 vol%SiC(HZTNC-SiC) were fabricated by spark plasma sintering.Their oxidation behavior was investigated over the temperature range of 1300-1500℃ for up to 60 min.Both HZTNC and HZTNC-SiC exhibited good oxidation resistance,and their weight change as a function of oxidation time obeyed a parabolic law.Through XRD,microstructure observation,and elemental mapping analysis of the oxide layers,it was found that the formation of Nb_(2) Zr_(6) O_(17),Hf_(6) Ta_(2) O_(17),and(Ta,Nb)_(2) O_(5) mixed-oxide layers effectively protected the matrix from further oxidation.Microcracks began to appear on the oxide layer of HZTNC at high temperatures after 60 min of oxidation.However,the addition of SiC in HZTNC suppressed these microcracks at high temperatures due to the active oxidation of SiC.Compared with the oxides formed on HZTNC,the additional formation of Hf(Zr)SiO_(4) on HZTNC-SiC could further improve its oxidation resistance over HZTNC ceramics. | Haoxuan Wang Shouye Wang Yejie Cao Wen Liu Yiguang Wang | 2021 | Journal of Materials Science & Technology2021，，1： | 2 |
| 14 | Lightweight 3D bioprinting with point by point photocuring显示文摘As photocrosslinkable materials,methacryloyl-modified hydrogels are widely used as bioinks in tissue engineering.Existing printing methods to use these hydrogels,including changing the viscosity of the material or mixing them with other printing components,have been explored,but their application has been limited due to low printing quality or high cost.In addition,the complex operation of bulky equipment restricts the application of these existing printing methods.This study presents a lightweight stereolithography-based three-dimensional(3D)bioprinting system with a smart mechanical and structural design.The developed bioprinter dimensions were 300 mm×300 mm×200 mm and it can be placed on a benchtop.The equipment has a mini bioink chamber to store a small amount of bioink for each printing.We systematically investigated the point-by-point curing process in the 3D bioprinting method,which can print mixed cells accurately and have good biocompatibility.Here,we provide a compact,low-cost stereolithography bioprinting system with excellent biocompatibility for 3D bioprinting with methacryloyl-modified hydrogels.It can be potentially used for drug screening,studying pathological mechanisms,and constructing biological disease models. | Peng Zhang Haoxuan Wang Peng Wang Yating Zheng Linxiang Liu Jun Hu Yande Liu Qing Gao Yong He | 2021 | Bioactive Materials2021，6，5： | 2 |
| 15 | Neuroprotective effect of the traditional Chinese herbal formula Tongxinluo: a PET imaging study in rats显示文摘Tongxinluo has been widely used in China for the treatment of acute stroke and for neuroprotection. However, there are few positron emission tomography(PET) studies on the neuroprotective effect of Tongxinluo on cerebral ischemia/reperfusion in small animals. In the present study, Tongxinluo superfine powder suspension or its vehicle was administered intragastrically to rats for 5 successive days before middle cerebral artery occlusion. 18F-fluorodeoxyglucose(FDG) small animal PET imaging showed that at 1 and 2 weeks after cerebral ischemia/reperfusion, glucose metabolism in the ischemic area was greater in rats that had received Tongxinluo than in those that had received the vehicle. Nissl staining showed that 2 weeks after cerebral ischemia/reperfusion, there was less neuronal loss in the prefrontal cortex in Tongxinluo-treated rats than in controls. In addition, Tongxinluo-treated animals showed better neurologic function and lower cerebral infarct volume than rats that received the vehicle. These findings suggest that Tongxinluo exhibits neuroprotective effects in cerebral ischemia/reperfusion injury and demonstrates that 18F-FDG small animal PET imaging is a useful tool with which to study the molecular pharmacology of traditional Chinese medicine. | Xiao Cheng Haoxuan Luo Lihua Zhou Lixin Wang Jingbo Sun Yan Huang Enli Luo Yefeng Cai | 2014 | Neural Regeneration Research2014，9，13： | 2 |
| 16 | A spontaneous thermo-sensitive female sterility mutation in rice enables fully mechanized hybrid breeding显示文摘Male sterility enables hybrid crop breeding to increase yields and has been extensively studied. But thermo-sensitive female sterility, which is an ideal property that may enable full mechanization in hybrid rice breeding, has rarely been investigated due to the absence of such germplasm. Here we identify the spontaneous thermo-sensitive female sterility 1 (tfs1) mutation that confers complete sterility under regular/high temperature and partial fertility under low temperature as a point mutation in ARGONAUTE7 (AGO7). AGO7 associates with miR390 to form an RNA-Induced Silencing Complex (RISC), which triggers the biogenesis of small interfering RNAs (siRNAs) from TRANS-ACTING3 (TAS3) loci by recruiting SUPPRESSOR OF GENE SILENCING (SGS3) and RNA-DEPENDENT RNA POLYMERASE6 (RDR6) to TAS3 transcripts. These siRNAs are known as tasiR-ARFs as they act in trans to repress auxin response factor genes. The mutant TFS1 (mTFS1) protein is compromised in its ability to load the miR390/miR390* duplex and eject miR390* during RISC formation. Furthermore, tasiR-ARF levels are reduced in tfs1 due to the deficiency in RDR6 but not SGS3 recruitment by mTFS1 RISC under regular/high temperature, while low temperature partially restores mTFS1 function in RDR6 recruitment and tasiR-ARF biogenesis. A miR390 mutant also exhibits female sterility, suggesting that female fertility is controlled by the miR390-AGO7 module. Notably, the tfs1 allele introduced into various elite rice cultivars endows thermo-sensitive female sterility. Moreover, field trials confirm the utility of tfs1 as a restorer line in fully mechanized hybrid rice breeding. | Haoxuan Li Chenjiang You Manabu Yoshikawa Xiaoyu Yang Haiyong Gu Chuanguo Li Jie Cui Xuemei Chen Nenghui Ye Jianhua Zhang Guanqun Wang | 2022 | Cell Research2022，32，10： | 2 |
| 17 | Recent progress on the modification of high nickel contentNCM:Coating,doping,and single crystallization显示文摘High nickel content layered cathodes,represented by NCM(LiNi_(x)Co_(y)Mn_(z)O_(2),x+y+z=1),are now widely employed in the market of electric vehicles,owing to their high energy density.With the gradual increase of nickel content and capacity,the issues on cycling life and safety become more serious.In this review,various strategies for improving the performance of high nickel NCM are summarized on the aspects of surface coating,ionic doping,and singlecrystal NCM.The coating strategy was separately described according to the physical property of coating species,including inert material coating,Li^(+)-conductor coating,electronic conductor coating,and mixed conductor coating.These coating species help to suppress the interfacial oxidation of electrolytes by NCM,improving the cycling life and safety.The elemental doping in the crystal lattice of NCM is then presented in the aspects of cation,anion,and mixed-ion doping,which are beneficial to stabilize the layered structure during charge–discharge and so promote the electrochemical performance.In quite recent years,the strategy of single-crystal NCM was demonstrated to be a promising pathway,owing to the dramatically reduced surface area and grain boundary.Finally,the remaining unsolved challenges and future strategies for further development of NCM cathode materials are outlined. | Junqing Yan Hao Huang Junfan Tong Wei Li Xiaohang Liu Haoxuan Zhang Heqin Huang Weidong Zhou | 2022 | Interdisciplinary Materials2022，1，3： | 2 |

| 20 | Integrated Ni-P-S nanosheets array as superior electrocatalysts for hydrogen generation显示文摘Searching for efficient and robust non-noble electrocatalysts for hydrogen generation is extremely desirable for future green energy systems.Here, we present the synthesis of integrated Ni-P-S nanosheets array including Ni_2P and NiS on nickel foam by a simple simultaneous phosphorization and sulfurization strategy. The resultant sample with optimal composition exhibits superior electrocatalytic performance for hydrogen evolution reaction(HER) in a wide pH range. In alkaline media, it can generate current densities of 10, 20 and 100 mA cm^(-2) at low overpotentials of only-101.9,-142.0 and-207.8 mV with robust durability. It still exhibits high electrocatalytic activities even in acid or neutral media. Such superior electrocatalytic performances can be mainly attributed to the synergistic enhancement of the hybrid Ni-P-S nanosheets array with integration microstructure. The kind of catalyst gives a new insight on achieving efficient and robust hydrogen generation. | Haoxuan Zhang Haibo Jiang Yanjie Hu Hao Jiang Chunzhong Li | 2017 | Green Energy & Environment2017，2，2： | 1 |
