| 1 | Process and challenges of stainless steel based bipolar plates for proton exchange membrane fuel cells显示文摘Proton exchange membrane fuel cell(PEMFC)powered automobiles have been recognized to be the ultimate solution to replace traditional fuel automobiles because of their advantages of PEMFCs such as no pollution,low temperature start-up,high energy density,and low noise.As one of the core components,the bipolar plates(BPs)play an important role in the PEMFC stack.Traditional graphite BPs and composite BPs have been criticized for their shortcomings such as low strength,high brittleness,and high processing cost.In contrast,stainless steel BPs(SSBPs)have recently attracted much attention of domestic and foreign researchers because of their excellent comprehensive performance,low cost,and diverse options for automobile applications.However,the SSBPs are prone to corrosion and passivation in the PEMFC working environment,which lead to reduced output power or premature failure.This review is aimed to summarize the corrosion and passivation mechanisms,characterizations and evaluation,and the surface modification technologies in the current SSBPs research.The non-coating and coating technical routes of SSBPs are demonstrated,such as substrate component regulation,thermal nitriding,electroplating,ion plating,chemical vapor deposition,and physical vapor deposition,etc.Alternative coating materials for SSBPs are metal coatings,metal nitride coatings,conductive polymer coatings,and polymer/carbon coatings,etc.Both the surface modification technologies can solve the corrosion resistance problem of stainless steel without affecting the contact resistance,however still facing restraints such as long-time stability,feasibility of low-cost,and mass production process.This paper is believed to enrich the knowledge of high-performance and long-life BPs applied for PEMFC automobiles. | Gaoyang Liu Faguo Hou Shanlong Peng Xindong Wang Baizeng Fang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，5： | 4 |
| 2 | Novel Au nanoparticles-inlaid titanium paper for PEM water electrolysis with enhanced interfacial electrical conductivity显示文摘Proton-exchange membrane water electrolysis(PEM WE)is a particularly promising technology for renewable hydrogen produc-tion.However,the excessive passivation of the gas diffusion layer(GDL)will seriously affect the high surface-contact resistance and result in energy losses.Thus,a mechanism for improving the conductivity and interface stability of the GDL is an urgent issue.In this work,we have prepared a hydrophilic and corrosion resistant conductive composite protective coating.The polydopamine(PDA)film on the Ti surface,which was obtained via the solution oxidation method,ensured that neither micropores nor pinholes existed in the final hybrid coatings.In-situ reduced gold nanoparticles(AuNPs)improved the conductivity to achieve the desired interfacial contact resistance and further enhanced the corrosion resistance.The surface composition of the treated samples was investigated using scanning electron microscopy(SEM),transmis-sion electron microscopy(TEM),X-ray diffraction(XRD),and Fourier transform infrared spectroscopy(FTIR).The results indicated that the optimized reaction conditions included a pH value of 3 of HAuCl_(4) solution with PDA deposition(48 h)on papers and revealed the lowest con-tact resistance(0.5 mΩ·cm^(2))and corrosion resistance(0.001μA·cm^(−2))in a 0.5 M H_(2)SO_(4)+2 ppm F−solution(1.7 V vs.RHE)among all the modified specimens,where RHE represents reversible hydrogen electrode.These findings indicated that the Au-PDA coating is very appropriate for the modification of Ti GDLs in PEM WE systems. | Yue Liu Shaobo Huang Shanlong Peng Heng Zhang Lifan Wang Xindong Wang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，5： | 2 |
| 3 | Chronic heat stress induces the disorder of gut transport and immune function associated with endoplasmic reticulum stress in growing pigs显示文摘Although high temperatures influence gut health,data on underlying mechanisms remains scant.Using a pig model,this study performed a global analysis on how chronic heat stress affects the transport and immune function of the gut through transcriptome,proteome,microbial diversity and flow cytometry.A total of 27 pigs with similar body weights were assigned into 3 groups,control(Con)group(23℃),chronic heat stressed(HS)group(33°C),and pair-fed(PF)group,in a controlled environment for 21 days.Our results showed that pigs in the HS group had reduced growth performance and diminished height of ileal villi(P<0.01).Transcriptome and proteome analyses demonstrated notable modification of expression of nutrients and ion transport-related transporters and gut mechanical barrier-related genes by chronic heart stress(P<0.05),suggesting damage of transport functions and the gut barrier.Chronic heat stress-induced endoplasmic reticulum stress also increased the synthesis of misfolded proteins,leading to upregulation of misfolded protein degradation and synthesis,as well as vesicle transport disorder(P<0.05).Energy supply processes were enhanced in the mitochondrion(P<0.05)to maintain biological processes with high energy demands.Furthermore,chronic heat stress activated complement cascade response-related genes and proteins in the gut mucosa(P<0.05).Our flow cytometry assays showed that the proportion of gut lymphocytes(CD4^(+)T cells,T cells,B cells in Peyer’s patch lymphocytes and CD4^(+)CD25^(+)T cells in intraepithelial lymphocytes)were significantly altered in the HS group pigs(P<0.05).In addition,the occurrence of gut microbial dysbiosis in the HS group pigs was characterized by increased potential pathogens(e.g.,Asteroleplasma,Shuttleworthia,Mycoplasma)and suppression of beneficial bacteria(e.g.,Coprococcus and Aeriscardovia),which are associated with gut immune function.Altogether,our data demonstrated that chronic heat stress induced gut transport and immune function disorder associated with endoplasmic reticulum stress in growing pigs. | Shanlong Tang Jingjing Xie Wei Fang Xiaobin Wen Chang Yin Qingshi Meng Ruqing Zhong Liang Chen Hongfu Zhang | 2022 | Animal Nutrition2022，，4： | 2 |

| 5 | Numerical simulation of the behaviors of test square for prehistoric earthen sites during archaeological excavation显示文摘During the process of archaeological excavation in the regions of Southeast China, collapse of test square usually occurs due to poor site-specific conditions. In this paper, the fast Lagrangian analysis of continua in three dimensions(FLAC3D) is employed to reveal the behaviors of test square. Taking the archaeological works in Liangzhu prehistoric earthen sites as the research background, the paper first introduces the geological setting, excavation procedure and monitoring scheme of the studied test square. Then, the deformation of four sides of the test square is modeled using FLAC3D. By comparison, it shows that the numerical results are consistent with the results from field monitoring. The result suggests that the numerical simulation can be effectively applied to representing the actual behaviors of the test square,which is helpful for determination of excavation scheme and stability evaluation of the test square during archaeological excavation. | Xudong Wang Zongren Yu Jingke Zhang Qinglin Guo Shanlong Yang Manli Sun | 2018 | Journal of Rock Mechanics and Geotechnical Engineering2018，10，3： | 1 |

| 9 | Aerial ammonia exposure induces the perturbation of the interorgan ammonia disposal and branched-chain amino acid catabolism in growing pigs显示文摘Aerial ammonia exposure leads to tissue damage and metabolic dysfunction.However,it is unclear how different organs are coordinated to defend against aerial ammonia exposure.Twenty-four pigs were randomly divided into 4 groups,exposed to 0,10,25 or 35 mg/m^(3) ammonia respectively for 25 d.After above 25 mg/m^(3) ammonia exposure,decreased aspartate(P=0.016),glutamate(P=0.030)and increased ornithine(P=0.002)were found in the ammonia-removing liver,and after high ammonia(35 mg/m^(3))exposure,glutamine synthetase(GS)expression was increased(P=0.012).An increased glutamate(P=0.004)and decreased glutaminase(GLS)expression(P=0.083)were observed in the lungs after high ammonia exposure.There was also an increasing trend of glutamine in the kidneys after high ammonia exposure(P=0.066).For branched-chain amino acid(BCAA)catabolism,high ammonia exposure increased BCAA content in both the lungs and muscle(P<0.05),whereas below 25 mg/m^(3) ammonia exposure increased BCAA only in the lungs(P<0.05).The expression of BCAA transaminase(BCAT1/2)and dehydrogenase complex(BCKDHA/B and DBT)were inhibited to a varying degree in the liver,lungs and muscle after above 25 mg/m^(3) ammonia exposure,especially high ammonia exposure.The expression of BCKDH complex and glutamate-glutamine metabolism-related genes were highly expressed in the liver,followed by the lungs and muscle(P<0.01),whereas the BCAT2 expression was highest in the lungs(P=0.002).Altogether,low ammonia exposure sufficed to evoke the urea cycle to detoxify ammonia in the liver.The process of ammonia removal in the liver and potential ability of the lungs to detoxify ammonia were enhanced with increasing ammonia.Furthermore,high ammonia exposure impaired the BCAA catabolism and decreased the transcripts of the BCAA catabolism-related enzymes,resulting in high BCAA content in extrahepatic tissues.Therefore,with aerial ammonia increasing,an increased urea cycle and glutamine synthesis were ammonia defensive strategies,and high ammonia exposure impaired the BCAA catabolism. | Shanlong Tang Chang Yin Jingjing Xie Jinglin Jiao Liang Chen Lei Liu Sheng Zhang Hongfu Zhang | 2021 | Animal Nutrition2021，，4： | 1 |
| 10 | Pectin modulates intestinal immunity in a pig model via regulating the gut microbiota-derived tryptophan metabolite-AhR-IL22 pathway显示文摘Background Pectin is a heteropolysaccharide that acts as an intestinal immunomodulator,promoting intestinal development and regulating intestinal flora in the gut.However,the relevant mechanisms remain obscure.In this study,pigs were fed a corn-soybean meal-based diet supplemented with either 5%microcrystalline cellulose(MCC)or 5%pectin for 3 weeks,to investigate the metabolites and anti-inflammatory properties of the jejunum.Result The results showed that dietary pectin supplementation improved intestinal integrity(Claudin-1,Occludin)and inflammatory response[interleukin(IL)-10],and the expression of proinflammatory cytokines(IL-1β,IL-6,IL-8,TNF-α)was down-regulated in the jejunum.Moreover,pectin supplementation altered the jejunal microbiome and tryptophan-related metabolites in piglets.Pectin specifically increased the abundance of Lactococcus,Enterococcus,and the microbiota-derived metabolites(skatole(ST),3-indoleacetic acid(IAA),3-indolepropionic acid(IPA),5-hydroxyindole-3-acetic acid(HIAA),and tryptamine(Tpm)),which activated the aryl hydrocarbon receptor(AhR)pathway.AhR activation modulates IL-22 and its downstream pathways.Correlation analysis revealed the potential relationship between metabolites and intestinal morphology,intestinal gene expression,and cytokine levels.Conclusion In conclusion,these results indicated that pectin inhibits the inflammatory response by enhancing the AhR-IL22-signal transducer and activator of transcription 3 signaling pathway,which is activated through tryptophan metabolites. | Guoqi Dang Xiaobin Wen Ruqing Zhong Weida Wu Shanlong Tang Chong Li Bao Yi Liang Chen Hongfu Zhang Martine Schroyen | 2023 | Journal of Animal Science and Biotechnology2023，14，4： | 1 |
| 11 | Phase diagrams, mechanisms and unique characteristics of alternating-structured polymer self-assembly via simulations显示文摘Alternating-structured polymers(ASPs), like alternating copolymers, regular multiblock copolymers and polycondensates, are very important polymer structures with broad applications in photoelectric materials. However, their self-assembly behaviors,especially the self-assembly of alternating copolymers, have not been clearly studied up to now. Meanwhile, the unique characteristics therein have not been systematically disclosed yet by both experiments and theories. Herein, we have performed a systematic simulation study on the self-assembly of ASPs with two coil alternating segments in solution through dissipative particle dynamics(DPD) simulations. Several morphological phase diagrams were constructed as functions of different impact parameters. Diverse self-assemblies were observed, including spherical micelles, micelle networks, worm-like micelles, disklike micelles, multimicelle aggregates, bicontinuous micelles, vesicles, nanotubes and channelized micelles. Furthermore, a morphological evolutionary roadmap for all these self-assemblies was constructed, along with which the detailed molecular packing models and self-assembly mechanisms for each aggregate were disclosed. The ASPs were found to adopt a folded-chain mechanism in the self-assemblies. Finally, the unique characteristics for the self-assembly of alternating copolymers were revealed especially, including(1) ultra-fine and uniform feature sizes of the aggregates;(2) independence of self-assembled structures from molecular weight and molecular weight distribution;(3) ultra-small unimolecular aggregates. We believe the current work is beneficial for understanding the self-assembly of alternating structured polymers in solution and can serve as a guide for the further experiments. | Shanlong Li Chunyang Yu Yongfeng Zhou | 2019 | Science China Chemistry2019，62，2： | 1 |

| 13 | Time-series surface water reconstruction method(TSWR)based on spatial distance relationship of multi-stage water boundaries显示文摘Spatiotemporal continuity of surface water datasets widely known for its significance in the surface water dynamic monitoring and assessments,are faced with drawbacks like cloud influence,which hinders the direct extraction of data from time-series remote sensing images.This study proposes a Time-series Surface Water Reconstruction method(TSWR).The initial stage of this method involves the effective use of remote sensing images to automatically construct multi-stage surface water boundaries based on Google Earth Engine(GEE).Then,we reconstructed regions the reconstruction of regions with missing water pixels using the distance relationship between the multi-stage water boundaries in previous and later periods.When applied to 10 large rivers around the world,this method yielded an overall accuracy of 98%for water extraction,an RMSE of 0.41 km2.Furthermore,time-series reconstruction tests conducted in 2020 on the Lancang and Danube rivers revealed a significant improvement in the image availability.These findings demonstrated that this method could not only be used to accurately reconstruct the surface water distribution missing water images,but also to depict a more pronounced time variation characteristic.The successful application of this method on GEE demonstrates its importance for use on large scales or in global studies. | Mingyang Li Shanlong Lu Cong Du Yong Wang Chun Fang Xinru Li Hailong Tang Muhammad Hasan Ali Baig Harrison Odion Ikhumhen | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
| 14 | Operando investigation of particle re-entrainment mechanism in electrostatic capture process on the lab-on-a-chip显示文摘Inhalable particle is a harmful air pollutant that causes a significant threat to people's health and ecological environments,which should be removed to purify air,but there exists limited removal efficiency due to particle re-entrainment.Here,Operando observation system based on microscopic visualization method is developed to make in situ test of particle migration,deposition and re-entrainment characteristics on a lab-on-a-chip to achieve the investigation in micro-level scale.The deposition evolution of charged particles is recorded in electric field region intuitively,which confirms the fracture of particle chain occurs during the growth process of deposited particles.It captures the instantaneous process that a larger particle with micron size due to the coagulation of submicron particles fractures from main body of the particle chain for the first time.The analysis of migration behavior of a single submicron particle near electrode surface demonstrates the direct influence of drag force on the fracture of particle chain.This work is the first-time visualization of dynamic process and mechanism elucidation of particle re-entrainment at the micron level,and the findings will provide the theory support for the particle re-entrainment mechanism and bring inspires of enhancing capture efficiency of inhalable particle. | Yong Zhu Yikun Zhang Xiaoyong Yang Shanlong Tao Mingxia Chen Wenfeng Shangguan | 2024 | Journal of Environmental Sciences2024，，2： | 0 |
| 15 | Nondestructive testing and assessment of consolidation effects of earthen sites显示文摘Earthen sites are widely distributed throughout China,and most of them belong to archaeological sites with significant values,which not only directly witness the origin,formation and development of Chinese civilization,but also possess important values for conservation and exhibition.Many researches and practices on their conservation and consolidation have been carried out:however,the consolidation effect is mainly judged by visual observation and expert evaluation.Scientific assessment of conservation and consolidation effects is a challenging issue.Many instruments in other fields cannot be directly applied to the conservation of cultural relics due to their peculiarity.In order to assess the effects of field conservation experiments,this paper tries to understand the consolidation effects at Liangzhu site using nondestructive or micro-damage methods,including thermo-physical parameters testing,infrared thermal imaging,high-density microelectrode resistivity testing,portable microscope observation,and hydrophilic and hydrophobic testing,and thereby explores the practicable methods for evaluating the properties of consolidation materials for earthen sites treatment. | Xudong Wang Qinglin Guo Shanlong Yang Dexuan Zhang Yanwu Wang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 0 |
| 16 | Biomimetic three-dimensional multilevel nanoarray electrodes with superaerophobicity as efficient bifunctional catalysts for electrochemical water splitting显示文摘The design and preparation of cost-effective and durable catalysts for electrochemical water splitting are significant for the development and application of hydrogen production.Herein,inspired by the underwater superaerophobicity of fish scales,a three-dimensional multilevel nanoarray electrode with superaerophobicity was designed and fabricated by the hydrothermal method to solve the bubble shielding effect in electrochemical reactions.Benefiting from the high specific surface area,superaerophobic properties,Al doping,the Al-CoS_(2)nanosheets(NSs)/nickel foam(NF)-30 exhibits outstanding electrocatalytic activity and superior durability for electrochemical water splitting in 1 M KOH.Significantly,the Al-CoS_(2)NSs/NF-30 only required extremely low overpotential of 176 mV for oxygen evolution reaction(OER)to reach a current density of 10 mA·cm^(-2).Al-CoS_(2)NSs/NF-30 was employed as bifunctional electrode for electrochemical water splitting with a cell voltage of 1.58 V at 10 mA·cm^(-2).Meanwhile,Al-CoS_(2) NSs/NF-30 exhibited excellent durability(250 h@10 mA·cm^(-2)and 50 h@100 mA·cm^(-2)).The cobalt-based catalyst(Al-CoS_(2) NSs/NF-30)with superaerophobicity exhibits excellent performance in activity and durability,therefore is a promising electrochemical water splitting catalyst. | Dongdong Wang Yue Liu Lili Liu Dongfang Shan Guixin Shen Shanlong Peng Heng Zhang Xindong Wang | 2023 | Nano Research2023，16，5： | 0 |
| 17 | RE-NiO_(x)(RE=Ce,Y,La)composite oxides coupled plasma catalysis for benzene oxidation and by-product ozone removal显示文摘Plasma-coupled catalysis is a promising volatile organic co mpounds(VOCs) removal technology because of its interactional principles of plasma decomposition and catalytic oxidation.However,the problem of harmful by-products is still in trouble.A series of rare earth doped RE-NiO_(x)(RE=Ce,Y,La) composite oxides were synthesized by metal organic frameworks(MOFs)-derived method for coupled plasma oxidation of benzene and by-product ozone removal.Compared with plasma alone,the 1%La-NiO_(x)catalyst shows the best enhancement of 50% for benzene conversion with complete removal of a maximum of 800 ppm ozone.The energy consumption for 90% benzene removal efficiency(η90%) is also reduced from 3600 to 1200 J/L.Characterization re sults of RE-NiO_(x) catalysts indicate that the doping of La causes interaction and synergistic effect between La and Ni,and the surface oxygen and lattice oxygen with defects play crucial roles in benzene oxidation and ozone decomposition,respectively.In addition,the decomposition mechanism of benzene and ozone under plasma is proposed.Plasma is responsible for the indiscriminate bond breaking in benzene and oxygen to form a variety of organic intermediates and ozone,while the La-NiO_(x) catalyst selectively oxidizes the intermediates to CO_(x)/H2O and decomposes the ozone into oxygen. | Yikun Zhang Zhidong Wei Yong Zhu Shanlong Tao Mingxia Chen Zhixiang Zhang Zhi Jiang Wenfeng Shangguan | 2023 | Journal of Rare Earths2023，41，6： | 0 |
