1PdAg bimetallic electrocatalyst for highly selective reduction of CO2 with low COOH^* formation energy and facile CO desorption显示文摘For electrocatalytic reduction of CO2 to CO,the stabilization of intermediate COOH^* and the desorption of CO^* are two key steps.Pd can easily stabilize COOH^*,whereas the strong CO^* binding to Pd surface results in severe poisoning,thus lowering catalytic activity and stability for CO2 reduction.On Ag surface,CO^* desorbs readily,while COOH^* requires a relatively high formation energy,leading to a high overpotential.In light of the above issues,we successfully designed the PdAg bimetallic catalyst to circumvent the drawbacks of sole Pd and Ag.The PdAg catalyst with Ag-terminated surface not only shows a much lower overpotential(-0.55 V with CO current density of 1 mA/cm^2)than Ag(−0.76 V),but also delivers a CO/H2 ratio 18 times as high as that for Pd at the potential of-0.75 V vs.RHE.The issue of CO poisoning is significantly alleviated on Ag-terminated PdAg surface,with the stability well retained after 4h electrolysis at-0.75 V vs.RHE.Density functional theory(DFT)calculations reveal that the Ag-terminated PdAg surface features a lowered formation energy for COOH^* and weakened adsorption for CO^*,which both contribute to the enhanced performance for CO2 reduction.Rui Lin Xuelu Ma Weng-Chon Cheong Chao Zhang Wei Zhu Jiajing Pei Kaiyue Zhang Bin Wang Shiyou Liang Yuxi Liu Zhongbin Zhuang Rong Yu Hai Xiao Jun Li Dingsheng Wang Qing Peng Chen Chen Yadong Li 2019Nano Research2019,12,11:7
2Identification and characterization of soybean dreg soluble dietary fibre by combination of extrusion pre-treatment and enzymatic modification显示文摘OBJECTIVES:Soybean dreg is a by-product of soy milk processing,which contains high levels of soluble dietary fibre(SDF).In this study,we aimed to provide comprehensive processes of pre-treated extrusion for the improving structure and properties of soybean dreg soluble dietary fibre(SDSDF),which would be a valuable approach to enhance physiological activity.METHODS:Here,we characteristic the functional role of SDSDF employing to extrusion pretreatment.Soybean dregs were pre-treated using the twin screw extrusion method followed by enzymatic modification using neutral protease,α-amylase,glucoamylase,and cellulose to produce SDSDF.The physical properties and antioxidant activity of SDSDF were investigated.RESULTS:The morphology and crystal structure of SDSDF were observed that,through extrusion processing and enzymatic modification,the SDSDF yield increased by 106.28%.Moreover,the surface structure showed block-shaped or reticular formations in the extruded SDSDF,and the size of block-shaped cells was about 10μm.Infrared spectroscopic analysis showed that a characteristic absorption peak of polysaccharide appeared at 1631 cm−1 during extrusion processing.However,after extrusion processing,decreased absorption peaks were observed for the extruded SDSDF.Furthermore,XRD analysis showed that the 2θdiffraction peak changed at 24.16°for the extruded SDSDF.CONCLUSIONS:The overall findings suggest that the water holding capacity(WHC),oil holding capacity(OHC),expansibility,and the water solubility were significantly decreased in extruded SDSDF.In addition,the scavenging ability of 1,1-diphenyl-2-picrylhydrazyl(DPPH),-OH,O_(2)^(-),and the total reducing power were significantly improved,indicating that beneficial changes had taken place in the crystal structure of cellulose or hemicellulose to improve the physiological activity in extruded SDSDF.Min Qu Yujia Liu Guang Zhang Sophia Jun Xue Hongchen Fan Yan Wang Shiyou Yu 2017Food Quality and Safety2017,1,2:3
3Movement of lateral hyporheic flow between stream and groundwater显示文摘The hyporheic zone plays an important role in groundwater and stream water quality protection. To investigate the stream-groundwater interaction mechanisms in the lateral hyporheic zone, this study examined Ma'an Creek in Chongqing during the dry season from December 2015 to April 2016. The water level, water temperature, pH and Cl. concentration in the hyporheic zone and groundwater were monitored in situ. The sediment permeability coefficient, stable isotopes of hydrogen and oxygen and concentration of DOC were analyzed. The results show that the water level changes of hyporheic zone and the movement of hyporheic flow were influenced significantly by the permeability coefficient of sediment. The hyporheic flow approximately10 cm from the stream bank was clearly affected by precipitation infiltration and evapotranspiration. During the study period,the groundwater recharged the stream, and the impact of groundwater on the hyporheic flow gradually decreased with the flow path. The hyporheic flow approximately 30 cm from the stream bank was still mainly affected by groundwater. Approximately10–30 cm from the stream bank, the mixing of groundwater with precipitation and stream water intensified. Due to the sediment properties, moisture accumulated approximately 10 cm from the stream bank and drained into the stream via hyporheic flow, with potential impacts on stream water quality.ZHANG Yu WANG JianLi YANG PingHeng XIE ShiYou 2017Science China Earth Sciences2017,60,11:2

6Severe acute respiratory syndrome coronavirus protein 6 mediates ubiquitin-dependent proteosomal degradation of N-Myc(and STAT) interactor显示文摘Severe acute respiratory syndrome coronavirus(SARS-Co V) encodes eight accessory proteins, the functions of which are not yet fully understood. SARS-Co V protein 6(P6) is one of the previously studied accessory proteins that have been documented to enhance viral replication and suppress host interferon(IFN) signaling pathways. Through yeast two-hybrid screening, we identified eight potential cellular P6-interacting proteins from a human spleen c DNA library. For further investigation, we targeted the IFN signaling pathway-mediating protein, N-Myc(and STAT) interactor(Nmi). Its interaction with P6 was confirmed within cells. The results showed that P6 can promote the ubiquitin-dependent proteosomal degradation of Nmi. This study revealed a new mechanism of SARS-Co V P6 in limiting the IFN signaling to promote SARS-Co V survival in host cells.Weijia Cheng Shiyou Chen Ruiling Li Yu Chen Min Wang Deyin Guo 2015Virologica Sinica2015,30,2:1

8Advances in solid Mg-ion electrolytes for solid-state Mg batteries显示文摘Rechargeable Mg batteries have attracted much attention in the past decade due to their high theoretical energy density and low production cost,in which the electrolyte is the key component that determines the overall performance.Applying solid Mg-ion electrolytes brings many benefits to rechargeable Mg bat-teries,which can improve safety under aggressive conditions and open opportunities for new electrode applications.After extensive investigations,researchers make major breakthroughs in the solid Mg-ion electrolyte field,especially in terms of Mg-ion conductivities.However,the development of solid-state Mg batteries is still at the early stage since their stable cycling has not been achieved yet.In this review,we introduce the Mg-ion conducting properties of current solid Mg-ion electrolytes,and then summarize the performances of corresponding solid-state Mg batteries.In addition,we provide a discussion on the application potentials and future directions of each type of solid Mg-ion electrolytes that are applied in solid-state Mg batteries.Yuepeng Pang Yu Zhu Fang Fang Dalin Sun Shiyou Zheng 2023Journal of Materials Science & Technology2023,,30:0
