| 1 | Hysteretic behavior of special shaped columns composed of steel and reinforced concrete(SRC)显示文摘This paper describes a series of experimental investigations on seventeen specimens of steel reinforced concrete special shaped(SRCSS) columns under low cyclic reversed loading using parallel crosshead equipment. Nine T-shaped SRC columns, four L-shaped SRC columns and four +-shaped SRC columns were tested to examine the effects of shape steel confi guration, loading angle, axial compressive ratio and shear-span ratio on the behavior(strength, stiffness, energy dissipation, ductility, etc.) of SRCSS column specimens. The failure modes and hysteretic performance of all the specimens were obtained in the tests. Test results demonstrate that the shear-span ratio is the main parameter affecting the failure modes of SRCSS columns. The specimens with small shear-span ratio are prone to shear failure, and the primary failure planes in SRCSS columns are parallel to the loading direction. As a result, there is a symmetry between positive and negative loading directions in the hysteretic curves of the SRCSS columns. The majority of displacement ductility coeffi cients for all the specimens are over 3.0, so that the SRCSS columns demonstrate a better deformation capacity. In addition, the equivalent viscous damping coeffi cients of all the specimens are greater than 0.2, indicating that the seismic behavior of SRCSS columns is adequate. Finally, the superposition theory was used to calculate the limits of axial compressive ratio for the specimens, and it is found that the test axial compressive ratio is close to or smaller than the calculated axial compressive ratio limit. | Chen Zongping Xu Jinjun Xue Jianyang | 2015 | Earthquake Engineering and Engineering Vibration2015，14，2： | 17 |
| 2 | Neuroprotective Autophagic Flux Induced by Hyperbaric Oxygen Preconditioning is Mediated by Cystatin C显示文摘We have previously reported that Cystatin C(CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen(HBO) preconditioning; however,the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. As a marker of autophagy inhibition, p62 was downregulated by HBO preconditioning and this was blocked by CysC knockdown. Besides, the beneficial effects of preserving lysosomal membrane integrity and enhancing autolysosome formation induced by HBO preconditioning were abolished in CysC-/-rats.Furthermore, we demonstrated that exogenous CysC reduced the neurological deficits and infarct volume after brain ischemic injury, while 3-methyladenine partially reversed this neuroprotection. In the present study, we showed that CysC is biochemically and morphologically essential for promoting autophagic flux, and highlighted the translational potential of HBO preconditioning and CysC for stroke treatment. | Zongping Fang Yun Feng Yuheng Li Jiao Deng Huang Nie Qianzhi Yang Shiquan Wang Hailong Dong Lize Xiong | 2019 | Neuroscience Bulletin2019，35，2： | 14 |
| 3 | Electrolyte materials for intermediate-temperature solid oxide fuel cells显示文摘Solid oxide fuel cells(SOFCs)directly convert chemical energy that is stored in a wide range of fuels into direct current electricity,with high efficiency and low emissions,via a series of electrochemical reactions at elevated operating temperatures(generally 400-1000℃).During such an energy conversion process,the properties of electrolyte materials determine the working principle and operating temperature of the SOFC.When considering the cost and stability,lowering the operating temperature is critical,and this has become one of the developing trends in SOFC research.The key point for realizing a reduction in operating temperature is to maintain low ohmic resistance of the electrolyte and low polarization resistance of the electrodes.In practice,the mechanical and chemical stability of the electrolyte is also a big concern.According to their differences in ion conduction mechanisms,there are three main types of electrolyte material available,namely,oxygen ion-conducting,proton-conducting,and dual ion-conducting electrolytes.In this review,we give a comprehensive summary of the recent advances in the development of these three types of electrolyte material for intermediate-temperature SOFCs.Both conductivity and stability are emphasized.In conclusion,the current challenges and future development prospects are discussed. | Huangang Shi Chao Su Ran Ran Jiafeng Cao Zongping Shao | 2020 | Progress in Natural Science:Materials International2020，30，6： | 12 |
| 4 | Photoproducts of tetracycline and oxytetracycline involving self-sensitized oxidation in aqueous solutions:Effects of Ca^(2+) and Mg^(2+)显示文摘Tetracyclines constitute one of the most important antibiotic families and represent a classic example of phototoxicity.The photoproducts of tetracyclines and their parent compounds have potentially adverse effects on natural ecosystem.In this study,the self-sensitized oxidation products of tetracycline (TC) and oxytetracycline (OTC) were determined and the effects of Ca2+ and Mg2+ on self-sensitized degradation were investigated.The Ca2+ and Mg2+ in the natural water sample accounted for enhancement (pH 7.3) and inhibition (pH 9.0) of photodegradation of TC and OTC due to the formation of metal-ions complexes.The formation of Mg2+ complexes was unfavorable for the photodegradation of the tetracyclines at both pH values.In contrast,the Ca2+ complexes facilitated the attack of singlet oxygen (1O2) arising from self-sensitization at pH 7.3 and enhanced TC photodegradation.For the first time,selfsensitized oxidation products of TC and OTC were verified by quenching experiments and detected by LC/ESI-DAD-MS.The products had a nominal mass 14 Da higher than the parent drugs (designated M+14),which resulted from the 1O2 attack of the dimethylamino group on the C-4 atom of the tetracyclines.The presence of Ca2+ and Mg2+ also affected the generation of M+14 due to the formation of metal-ions complexes with TC and OTC.The findings suggest that the metal-ion complexation has significant impact on the selfsensitized oxidation processes and the photoproducts of tetracyclines. | Yong Chen Hua Li Zongping Wang Tao Tao Chun Hu | 2011 | Journal of Environmental Sciences2011，23，10： | 12 |
| 5 | Soil hydraulic conductivity as affected by vegetation restoration age on the Loess Plateau,China显示文摘The Loess Plateau of China has experienced extensive vegetation restoration in the past several decades,which leads to great changes in soil properties such as soil bulk,porosity,and organic matter with the vegetation restoration age.And these soil properties have great effect on the soil infiltration and soil hydraulic conductivity.However,the potential changes in soil hydraulic conductivity caused by vegetation restoration age have not been well understood.This study was conducted to investigate the changes in soil hydraulic conductivity under five grasslands with different vegetation restoration ages(3,10,18,28 and 37 years)compared to a slope farmland,and further to identify the factors responsible for these changes on the Loess Plateau of China.At each site,accumulative infiltration amount and soil hydraulic conductivity were determined using a disc permeameter with a water supply pressure of –20 mm.Soil properties were measured for analyzing their potential factors influencing soil hydraulic conductivity.The results showed that the soil bulk had no significant changes over the initial 20 years of restoration(P>0.05);the total porosity,capillary porosity and field capacity decreased significantly in the grass land with 28 and 37 restoration ages compared to the slope farmland;accumulative infiltration amount and soil hydraulic conductivity were significantly enhanced after 18 years of vegetation restoration.However,accumulative infiltration amount and soil hydraulic conductivity fluctuated over the initial 10 years of restoration.The increase in soil hydraulic conductivity with vegetation restoration was closely related to the changes in soil texture and structure.Soil sand and clay contents were the most influential factors on soil hydraulic conductivity,followed by bulk density,soil porosity,root density and crust thickness.The Pearson correlation coefficients indicated that the soil hydraulic conductivity was affected by multiply factors.These results are helpful to understand the changes in hydrological and erosion processes response to vegetation succession on the Loess Plateau. | REN Zongping ZHU Liangjun WANG Bing CHENG Shengdong | 2016 | Journal of Arid Land2016，8，4： | 9 |
| 6 | Seismic performance of recycled concrete-filled square steel tube columns显示文摘An experimental study on the seismic performance of recycled concrete-filled square steel tube(RCFST) columns is carried out.Six specimens were designed and tested under constant axial compression and cyclic lateral loading.Two parameters, replacement percentage of recycled coarse aggregate(RCA) and axial compression level, were considered in the test.Based on the experimental data, the hysteretic loops, skeleton curves, ductility, energy dissipation capacity and stiffness degradation of RCFST columns were analyzed.The test results indicate that the failure modes of RCFST columns are the local buckling of the steel tube at the bottom of the columns, and the hysteretic loops are full and their shapes are similar to normal CFST columns.Furthermore, the ductility coefficient of all specimens are close to 3.0, and the equivalent viscous damping coefficient corresponding to the ultimate lateral load ranges from 0.323 to 0.360, which demonstrates that RCFST columns exhibit remarkable seismic performance. | Chen Zongping Jing Chenggui Xu Jinjun Zhang Xianggang | 2017 | Earthquake Engineering and Engineering Vibration2017，16，1： | 8 |
| 7 | Effects of freeze-thaw on soil erosion processes and sediment selectivity under simulated rainfall显示文摘The freeze-thaw(FT) processes affect an area of 46.3% in China. It is essential for soil and water conservation and ecological construction to elucidate the mechanisms of the FT processes and its associated soil erosion processes. In this research, we designed the control simulation experiments to promote the understanding of FT-water combined erosion processes. The results showed that the runoff of freeze-thaw slope(FTS) decreased by 8% compared to the control slope(CS), and the total sediment yield of the FTS was 1.10 times that of the CS. The sediment yield rate from the FTS was significantly greater than that from the CS after 9 min of runoff(P<0.01). Both in FTS and CS treatments, the relationships between cumulative runoff and sediment yield can be fitted well with power functions(R2>0.98, P<0.01). Significant differences in the mean weight diameter(MWD) values of particles were observed for washed particles and splashed particles between the CS and the FTS treatments in the erosion process(P<0.05). The mean MWD values under CS were smaller than those under FTS for both washed and splashed particles. The ratio of the absolute value of a regression coefficient between the CS and the FTS was 1.15, being roughly correspondent with the ratio of K between the two treatments. Therefore, the parameter a of the power function between cumulative runoff and sediment yield could be an acceptable indicator for expressing the soil erodibility. In conclusion, the FTS exhibited an increase in soil erosion compared to the CS. | WANG Tian LI Peng REN Zongping XU Guoce LI Zhanbin YANG Yuanyuan TANG Shanshan YAO Jingwei | 2017 | Journal of Arid Land2017，9，2： | 8 |
| 8 | Dynamics of ecosystem carbon stocks during vegetation restoration on the Loess Plateau of China显示文摘In the last few decades, the Loess Plateau had experienced an extensive vegetation restoration to reduce soil erosion and to improve the degraded ecosystems. However, the dynamics of ecosystem carbon stocks with vegetation restoration in this region are poorly understood. This study examined the changes of carbon stocks in mineral soil(0–100 cm), plant biomass and the ecosystem(plant and soil) following vegetation restoration with different models and ages. Our results indicated that cultivated land returned to native vegetation(natural restoration) or artificial forest increased ecosystem carbon sequestration. Tree plantation sequestered more carbon than natural vegetation succession over decades scale due to the rapid increase in biomass carbon pool. Restoration ages had different effects on the dynamics of biomass and soil carbon stocks. Biomass carbon stocks increased with vegetation restoration age, while the dynamics of soil carbon stocks were affected by sampling depth. Ecosystem carbon stocks consistently increased after tree plantation regardless of the soil depth; but an initial decrease and then increase trend was observed in natural restoration chronosequences with the soil sampling depth of 0–100 cm. Moreover, there was a time lag of about 15–30 years between biomass production and soil carbon sequestration in 0–100 cm, which indicated a long-term effect of vegetation restoration on deeper soil carbon sequestration. | WANG Kaibo DENG Lei REN Zongping SHI Weiyu CHEN Yiping SHANG-GUAN Zhouping | 2016 | Journal of Arid Land2016，8，2： | 7 |
| 9 | Photolysis of chlortetracycline in aqueous solution:Kinetics,toxicity and products显示文摘The aqueous photodegradation of the widely used antibiotic chlortetracycline(CTC) was investigated under simulated sunlight.The quantum yield of photodegradation increased from 3.3 × 10-4 to 8.5 × 10-3 within the pH range of 6.0 to 9.0.The presence of Ca2+,Fe3+,and NO3-enhanced the photodegradation of CTC,whereas Mg2+,Mn2+,and Zn2+ inhibited the degradation with the order Mn2+ > Zn2+ > Mg2+ at pH 7.3.The monovalent cations(Na+ and K+) had negligible effect on the photolysis of CTC.Fulvic acid(FA) decreased the photodegradation of CTC due to light screening effect.Hydrogen peroxide(H2O2) was formed concurrently with direct photodegradation of CTC.The generation rate of H2O2 increased from 0.027 to 0.086 μmol/(L.min) when the pH ranged from 6.0 to 9.0.The CTC solution was about three-fold more toxic to the Photobacterium phosphoreum bacteria after irradiation,suggesting that the photoproducts and H2O2 formed in the CTC solution exhibited high risk on the bacteria.By LC-ESI(+)-MS,the photoproducts of CTC were identified.The direct photodegradation of CTC was involved in hydroxylation and N-demethyl/dedismethyl processes.The main photoproducts included the iso-CTC analog containing hydroxyl groups(m/z 511.4 and 495.4),and the N-demethyl/dedismethyl products of the photoproduct m/z 495.4(m/z 481.3 and 467.4).In addition,the photochemical dechlorination of CTC led to tetracycline(m/z 445.5). | Yong Chen Hua Li Zongping Wang Tao Tao Dongbin Wei Chun Hu | 2012 | Journal of Environmental Sciences2012，24，2： | 6 |
| 10 | Effects of arbuscular mycorrhizal fungi on the drought resistance of the mining area repair plant Sainfoin显示文摘To solve the problem of lack of water in arid areas and barren soil in the process of ecological restoration,the growth and drought resistance of Sainfoin(Onobrychis viciifolia Scop.) was studied by inoculation of AMF(arbuscular mycorrhizal fungi), under drought stress. The results show that the inoculation of AMF can significantly improve the growth and mycorrhizal infection rate of Sainfoin and accelerate the absorption of water and nutrients by the roots compared with uninoculated plants. On the 40 th day under drought stress, the relative water content, total nitrogen and total phosphorus content of the leaves of inoculated plants increased by 7.27%, 4.21% and 2.40%, respectively, the osmotic adjustment property in plant cells was improved, the protective enzyme system was improved and membrane lipid peroxidation was reduced. The inoculation of AMF can slow down the damage from drought, improve the drought resistance of Sainfoin, and will be of great significance to the ecologic restoration in arid areas. | Kong Jing Pei Zongping Du Min Sun Gan Zhang Xin | 2014 | International Journal of Mining Science and Technology2014，24，4： | 6 |
| 11 | Direct growth of ordered N-doped carbon nanotube arrays on carbon fiber cloth as a free-standing and binder-free air electrode for flexible quasi-solid-state rechargeable Zn-Air batteries显示文摘The development of an air electrode that is flexible in physical property and highly active and durable at different geometric status for both oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)is of crucial importance for the rational design of flexible rechargeable Zn-air batteries(ZABs).Considering their good elasticity,high conductivity,and superior thermal and chemical stability,carbon nanotubes have been widely used as a catalyst support in various electrocatalysts,while oxide or metal nanoparticles have been frequently deposited on the carbon nanotube substrate to perform as the active materials.Considering the poor contact between active materials and carbon nanotubes may introduce a challenge for long-term operating stability,in particular in flexible devices,pure carbon electrocatalyst is highly appreciated.Herein,a free-standing air electrode with cobalt nanoparticles encapsulated N-codoped carbon nanotube arrays uniformly grown on the surface of carbon fiber cloth is developed by a two-step in situ growth method.Such a carbon-based electrode shows outstanding activity for both ORR and OER.The flexible ZAB with such air electrode shows superior flexibility and stability working under extreme bending conditions.Moreover,the polarization and round-trip efficiency for the flexible battery is 0.67 V and 64.4%at 2 mA/cm2,respectively,even after being operated for 30 hours.This study provides a feasible way to design all carbon-based free-standing and flexible electrode and enlightens the electrode design for flexible energy conversion/storage devices. | Qian Lu Xiaohong Zou Kaiming Liao Ran Ran Wei Zhou Meng Ni Zongping Shao | 2020 | Carbon Energy2020，2，3： | 6 |
| 12 | Recent advances and perspectives of fluorite and perovskite-based dual-ion conducting solid oxide fuel cells显示文摘High-temperature solid-state electrolyte is a key component of several important electrochemical devices,such as oxygen sensors for automobile exhaust control,solid oxide fuel cells(SOFCs) for power generation,and solid oxide electrolysis cells for H_(2) production from water electrolysis or CO_(2) electrochemical reduction to value-added chemicals.In particular,internal diffusion of protons or oxygen ions is a fundamental and crucial issue in the research of SOFCs,hypothetically based on either oxygen-ionconducting electrolytes or proton-conducting electrolytes.Up to now,some electrolyte materials based on fluorite or perovskite structure were found to show certain degree of dual-ion transportation capability,while in available electrolyte database,particularly in the field of SOFCs,such dual-ion conductivity was seriously overlooked.Actually,few concerns arising to the simultaneous proton and oxygen-ion conductivities in electrolyte of SOFCs inevitably induce various inadequate and confusing results in literature.Understanding dual-ion transportation behavior in electrolyte is indisputably of great importance to explain some unusual fuel cell performance as reported in literature and enrich the knowledge of solid state ionics.On the other hand,exploration of novel dual-ion conducting electrolytes will benefit the development of SOFCs.In this review,we provide a comprehensive summary of the understanding of dual-ion transportation in solid electrolyte and recent advances of dual-ion conducting SOFCs.The oxygen ion and proton conduction mechanisms at elevated temperature inside oxide-based electrolyte materials are first introduced,and then(mixed) oxygen ion and proton conduction behaviors of fluorite and perovskite-type oxides are discussed.Following on,recent advances in the development of dual-ion conducting SOFCs based on fluorite and perovskite-type single-phase or composite electrolytes,are reviewed.Finally,the challenges in the development of dual-ion conducting SOFCs are discussed and future prospects are proposed. | Jiafeng Cao Chao Su Yuexia Ji Guangming Yang Zongping Shao | 2021 | Journal of Energy Chemistry2021，30，6： | 5 |
| 13 | Neuroprotective effects of combined lead and cadmium,as well as N-acetylcysteine,on cerebral cortical neurons following lipid peroxidation injury显示文摘BACKGROUND:Studies have reported the antioxidant effects of lead and cadmium in the central nervous system,but very few have addressed the combined toxicity of lead and cadmium.The mechanisms by which these combined heavy metals are toxic,as well as how to protect cells from these agents,remains poorly understood. OBJECTIVE:Primary cultured rat cortical neurons were used to determine the effects of combined lead and cadmium on levels of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD), catalase(CAT),and acetylcholinesterase(AChE),as well as malondialdehyde(MDA),and to evaluate the neuroprotective effects of N-acetylcysteine(NAC). DESIGN,TIME AND SETTING:An in vitro toxicological observation was performed at the Comparative Medicine Center of Yangzhou University from August 2007 to April 2008. MATERIALS:Lead acetate,cadmium acetate,and NAC were purchased from Sigma-Aldrich(St. Louis,USA).Commercial kits of GSH-Px,SOD,CAT,AChE,and MDA were purchased from Nanjing Jiancheng Bioengineering Institute,Nanjing,China. METHODS:The cerebral cortical neurons were isolated from newborn Sprague dawley rats at 24 hours after birth and primary cultured for 6 days.Thereafter,the cells were treated with a range of cadmium doses(0,5.0,and 10.0μmol/L),lead doses(0,1.0,and 2.0μmol/L),or a combination of the two for 12 hours at 37℃in a 5%CO_2 incubator,respectively.In addition,the cells were incubated with different doses of cadmium and/or lead and(0 and 50μmol/L) NAC for 12 hours to assess the protective effects on cell survival. MAIN OUTCOME MEASURES:The activity of SOD,GSH-Px,CAT,and AChE,as well as MDA content,in the cell lysates was detected using commercial kits. RESULTS:At 12 hours after treatment,compared to the control group,activity of GSH-Px,SOD, and AChE in the lead,cadmium,or combined treated cells was significantly decreased with increasing doses of cadmium/or lead(P<0.05),but CAT activity and MDA levels were significantly increased(P<0.05).The combination of cadmium and lead led to higher levels of toxicity than individual exposure. CONCLUSION:The degree of oxidative damage increased when the two heavy metals were combined.NAC protected neonatal cortical neurons by increasing activity of anti-oxidative enzymes, and reducing lipid peroxidation,but the reduction was not statistically significant. | Yumei Zhang Hao Lu Yan Yuan Xuezhong Liu Zongping Liu | 2009 | Neural Regeneration Research2009，4，11： | 4 |

| 15 | Partial oxidation of methane to syngas in a mixed-conducting oxygen permeable membrane reactor显示文摘Mixed-conducting oxygen permeable membranes represent a class of novel ceramic membranes, which exhibit mixed oxygen ionic and electronic conductivities. At high temperatures, oxygen can permeate through the membrane from the high to low oxygen pressure side under an oxygen concentration gradient. Theoretically, the permselectivity of oxygen is 100%. Recently, anovel mixed-conducting membrane-Ba0.5Sr0.5Coo.8Feo.2O3-δ has been developed, which showsextremely high oxygen permeability and promising stability. Furthermore, the reactor made with such membranes was successfully applied to the partial oxidation of methane to syngas reaction using air as the oxygen source, which realized the coupling of the separation of oxygen from air and the partial oxidation of membrane reaction in one process. At 850℃, methane conversion > 88%, CO selectivity >97% and oxygen permeation rate of about 7.8 mL/(cm2 ·min) were obtained. | Hui Dong Guoxing Xiong Zongping Shao Shenglin Liu Weishen Yang | 2000 | Chinese Science Bulletin2000，45，3： | 3 |
| 16 | Prognostic value of systemic immune- inflammation index in acute/subacute patients with cerebral venous sinus thrombosis显示文摘Objective To evaluate the prognosis values of systemic immune-inflammation index(SII)in non-chronic cerebral venous sinus thrombosis(CVST).Methods patients with CVST,admitted to the First Affiliated Hospital of Zhengzhou University,were retrospectively identified from January 2013 to December 2018.We selected patients in acute/subacute phase from database.Functional outcomes of patients were evaluated with the modified Rankin Scale(mRS)-mRS 3-6 as poor outcomes and mRS 6 as death.The overall survival time was defined as the date of onset to the date of death or last follow-up date.Survival analysis was described by the Kaplan-Meier curve and Cox regression analysis.Multivariate logistic regression analysis assessed the relationship between SII and poor functional outcome.The area under the Receiver Operating Curve curve(AUC)was estimated to evaluate the ability of SII in prediction.Results A total of 270 patients were included and their duration of follow-up was 22 months(6-66 months),of whom 31 patients had poor outcomes and 24 patients dead.Cox regression analysis showed that SII(HR=1.304,95%CI:1.101 to 1.703,p=0.001)was a predictor of death in non-chronic CVST.Patients with higher SII presented lower survival rates(p=0.003).The AUC of SII was 0.792(95%CI:0.695 to 0.888,p=0.040)with a sensitivity of 69.6%and specificity of 80.1%.Subgroups analysis demonstrated that SII was an important predictor of poor outcomes in male(OR=1.303,95%CI:1.102 to 1.501,p=0.011)and pregnancy/puerperium female(OR=1.407,95%CI:1.204 to 1.703,p=0.034).Conclusions SII was a potential predictor in the poor prognosis of patients with acute/subacute CVST,especially in male and pregnancy/puerperium female. | Shen Li Kai Liu Yuan Gao Lu Zhao Rui Zhang Hui Fang Yongli Tao Hongbing Liu Jiawei Zhao Zongping Xia Yuming Xu Bo Song | 2020 | Stroke & Vascular Neurology2020，5，4： | 3 |
| 17 | Slightly ruthenium doping enables better alloy nanoparticle exsolution of perovskite anode for high-performance direct-ammonia solid oxide fuel cells显示文摘Fuel flexibility is one of the most distinguished advantages of solid oxide fuel cells(SOFCs)over other low-temperature fuel cells.Furthermore,the combination of ammonia fuel and SOFCs technology should be a promising clean energy system after considering the high energy density,easy transportation/storage,matured synthesis technology and carbon-free nature of NH_(3) as well as high efficiency of SOFCs.However,the large-scale applications of direct-ammonia SOFCs(DASOFCs)are strongly limited by the inferior anti-sintering capability and catalytic activity for ammonia decomposition reaction of conventional nickel-based cermet anode.Herein,a slightly ruthenium(Ru)doping in perovskite oxides is proposed to promote the alloy nanoparticle exsolution,enabling better DA-SOFCs with enhanced power outputs and operational stability.After treating Ru-doped Pr_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.75)Ru_(0.05)O_(3-δ) single-phase perovskite in a reducing atmosphere,in addition to the formation of two layered Ruddlesden-Popper perovskites and Pr_(2)O_(3) nanoparticles(the same as the Ru-free counterpart,Pr_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)),the exsolution of CoFeRu-based alloy nanoparticles is remarkably promoted.Such reduced Pr_(0.6)Sr0.4Co_(0.2)Fe_(0.75)Ru_(0.05)O_(3-δ) composite anode shows superior catalytic activity and stability for NH_(3) decomposition reaction as well as anti-sintering capability in DA-SOFCs to those of reduced Pr0.6Sr0.4Co0.2Fe0.8O_(3-δ)due to the facilitated nanoparticle exsolution and stronger nanoparticle/substrate interaction.This work provides a facile and effective strategy to design highly active and durable anodes for DA-SOFCs,promoting large-scale applications of this technology. | Xiandong Xiong Jian Yu Xiaojian Huang Dan Zou Yufei Song Meigui Xu Ran Ran Wei Wang Wei Zhou Zongping Shao | 2022 | Journal of Materials Science & Technology2022，，30： | 3 |
| 18 | Electrolyte Engineering for Safer Lithium-Ion Batteries:A Review显示文摘Despite being widely used in people's daily life,the safety issue of lithium-ion batteries(LIBs)has become the major barrier for them to be applied in electrical vehicles(EVs)or large-scale energy storage.Typically,due to the use of liquid electrolytes containing flammable solvents which are easily oxidized by excessive and accumulated heat,the potential thermal runaway is a major safety concern for traditional LIBs.A strategy for a safer electrolyte design is controlling the flammability and volatility of the liquid electro-lytes,to effectively prevent thermal runaway,thus avoiding fire or other risks.Through this study,the mechanisms of thermal runa-way and the recent progress in electrolyte engineering toward LIBs were summarized,covering the major strategies including adding flame-retardants,the utilization of ionic liquid electrolytes and solid electrolytes.The characteristics,strengths and weaknesses of different strategies were discussed.New designing directions of safer electrolytes for the LIBs were also provided. | Chencheng Cao Yijun Zhong Zongping Shao | 2023 | Chinese Journal of Chemistry2023，41，9： | 3 |
| 19 | Freeze–thaw effects on erosion process in loess slope under simulated rainfall显示文摘Seasonal freeze–thaw processes have led to severe soil erosion in the middle and high latitudes.The area affected by freeze–thaw erosion in China exceeds 13%of the national territory.So understanding the effect of freeze–thaw on erosion process is of great significance for soil and water conservation as well as for ecological engineering.In this study,we designed simulated rainfall experiments to investigate soil erosion processes under two soil conditions,unfrozen slope(UFS)and frozen slope(FS),and three rainfall intensities of 0.6,0.9 and 1.2 mm/min.The results showed that the initial runoff time of FS occurred much earlier than that of the UFS.Under the same rainfall intensity,the runoff of FS is 1.17–1.26 times that of UFS;and the sediment yield of FS is 6.48–10.49 times that of UFS.With increasing rainfall time,rills were produced on the slope.After the appearance of the rills,the sediment yield on the FS accounts for 74%–86%of the total sediment yield.Rill erosion was the main reason for the increase in soil erosion rate on FS,and the reduction in water percolation resulting from frozen layers was one of the important factors leading to the advancement of rills on slope.A linear relationship existed between the cumulative runoff and the sediment yield of UFS and FS(R2>0.97,P<0.01).The average mean weight diameter(MWD)on the slope erosion particles was as follows:UFS0.9(73.84μm)>FS0.6(72.30μm)>UFS1.2(72.23μm)>substrate(71.23μm)>FS1.2(71.06μm)>FS0.9(70.72μm).During the early stage of the rainfall,the MWD of the FS was relatively large.However,during the middle to late rainfall,the particle composition gradually approached that of the soil substrate.Under different rainfall intensities,the mean soil erodibility(MK)of the FS was 7.22 times that of the UFS.The ratio of the mean regression coefficient C2(MC2)between FS and UFS was roughly correspondent with MK.Therefore,the parameter C2 can be used to evaluate soil erodibility after the appearance of the rills.This article explored the influence mechanism of freeze–thaw effects on loess soil erosion and provided a theoretical basis for further studies on soil erosion in the loess hilly regions. | SU Yuanyi LI Peng REN Zongping XIAO Lie ZHANG Hui | 2020 | Journal of Arid Land2020，12，6： | 2 |
| 20 | Development of nickel based cermet anode materials in solid oxide fuel cells–Now and future显示文摘High temperature solid oxide fuel cell(SOFC)is the most efficient and clean energy conversion technology to electrochemically convert the chemical energy of fuels such as hydrogen,natural gas and hydrocarbons to electricity,and also the most viable alternative to the traditional thermal power plants.However,the power output of a SOFC critically depends on the characteristics and performance of its key components:anode,electrolyte and cathode.Due to the highly reducing environment and strict requirements in electrical conductivity and catalytic activity,there are limited choices in the anode materials of SOFCs,particularly for operation in the intermediate temperature range of 500–800C.Among them,Ni-based cermets are the most common and popular anode materials of SOFCs.The objective of this paper is to review the development of Ni-based anode materials in SOFC from the viewpoints of materials microstructure,performance and industrial scalability associated with the fabrication and optimization processes.The latest advancement in nano-structure architecture,contaminant tolerance and interface optimization of Ni-based cermet anodes is presented.And at the end of this paper,we propose and appeal for the collaborative work of scientists from different disciplines that enable the inter-fusion research of fabrication,microanalysis and modelling,aiming at the challenges in the development of Ni-based cermet anodes for commercially viable intermediate temperature SOFC or IT-SOFC technologies. | Yu Liu Zongping Shao Toshiyuki Mori San Ping Jiang | 2021 | Materials Reports(Energy)2021，1，1： | 2 |
