1Copper-Bismuth Bimetallic Microspheres for Selective Electrocatalytic Reduction of CO2 to Formate显示文摘Summary of main observation and conclusion Electrocatalytic carbon dioxide reduction holds great promise for reducing the atmospheric CO2 level and alleviating the energy crisis. High-performance electrocatalysts are often required in order to lower the high overpotential and expedite the sluggish reaction kinetics of CO2 electroreduction. Copper is a promising candidate metal. However, it usually suffers from the issues of poor stability and low product selectivity. In this work, bimetallic Cu-Bi is obtained by reducing the microspherical copper bismuthate (CuBi2O4) for selectively catalyzing the CO2 reduction to formate (HCOO-). The bimetallic Cu-Bi electrocatalyst exhibits high activity and selectivity with the Faradic efficiency over 90% in a wide potential window. A maximum Faradaic efficiency of ~95% is obtained at -0.93 V versus reversible hydrogen electrode. Furthermore, the catalyst shows high stability over 6 h with Faradaic efficiency of -95%. This study provides an important clue in designing new functional materials for CO2 electroreduction with high activity and selectivity.Lin Jia Hui Yang Jun Deng Junmei Chen Yuan Zhou Pan Ding Leigang Li Na Han Yanguang Li 2019Chinese Journal of Chemistry2019,37,5:8
2Foraging behavior of the Greater White-fronted Goose(Anser albifrons) wintering at Shengjin Lake: diet shifts and habitat use显示文摘Background: The habitat use and foraging behaviors of waterbirds are closely related to the distribution and abundance of their food resources. Reductions in food supply can cause waterbirds to shift their habitats and adjust their foraging behaviors to meet their nutritional requirements and increase fitness. Seasonal withdraw of the water levels in the river-connected lakes in the middle and lower Yangtze River floodplain provides abundant food resources for the wintering Greater White-fronted Goose(Anser albifrons). Sedge(Carex) meadows are critical foraging habitats for herbivorous waterbirds in the hydro-fluctuation belt, which changes with hydrological conditions and climate. This study aimed to examine the behavioral responses of the Greater White-fronted Goose to temporal-spatial changes of food availability in the Sedge meadows.Methods: Fields surveys were carried out at Shengjin Lake from November 2017 to April 2018. According to the phenology of Shengjin Lake, we divided the wintering season into three periods. The food density, minimum temperature, food items, grass height, and number of foraging geese were surveyed, and samples of the foraging behavior were collected. We analyzed the relationship of the foraging behavior and habitat use relative to the food resources, using correlation and linear regression analyses.Results: Along with the temporal-spatial variation and exploitation of food resources, the food abundance and items varied widely among the foraging sites. Over the whole wintering period, the foraging habitat with the highest utilization rate was the meadows, followed by the paddy fields, and then mudflats. Furthermore, the utilization of the meadows showed a bimodal distribution trend, while the paddy fields showed a unimodal trend, and a decreasing trend was seen in the mudflats over the whole wintering period. The results of the generalized linear model showed that the foraging rate was related to the food density and grass height, with a linearly increasing trend during the winter.Conclusions: With the change of food resources in the three habitats, the habitats used by the Greater White-fronted Geese shifted from meadows in the hydro-fluctuation belt to the paddy fields, and then back to the meadows. The time budget for foraging activities increased correspondingly, and there was an increase in the foraging rate to compensate for food shortages.Yanguang Fan Lizhi Zhou Lei Cheng Yunwei Song Wenbin Xu 2020Avian Research2020,11,1:5
3Selective electrochemical production of hydrogen peroxide at zigzag edges of exfoliated molybdenum telluride nanoflakes显示文摘The two-electron reduction of molecular oxygen represents an effective strategy to enable the green,mild and on-demand synthesis of hydrogen peroxide.Its practical viability,however,hinges on the development of advanced electrocatalysts,preferably composed of non-precious elements,to selectively expedite this reaction,particularly in acidic medium.Our study here introduces 2H-MoTe2 for the first time as the efficient non-precious-metal-based electrocatalyst for the electrochemical production ofhydrogen peroxide in acids.We show that exfoliated 2H-MoTe2 nanoflakes have high activity(onset overpotential〜140 mV and large mass activity of 27 A g^-1 at 0.4 V versus reversible hydrogen electrode),great selectivity(H2O2 percentage up to 93%)and decent stability in 0.5 M H2SO4.Theoretical simulations evidence that the high activity and selectivity of 2H-MoTe2 arise from the proper binding energies of HOO*and O*at its zigzag edges that jointly favor the two-electron reduction instead of the four-electron reduction of molecular oxygen.Xuan Zhao Yu Wang Yunli Da Xinxia Wang Tingting Wang Mingquan Xu Xiaoyun He Wu Zhou Yafei Li Jonathan NColeman Yanguang Li 2020National Science Review2020,7,8:3

6Strong phonon localization in PbTe with dislocations and large deviation to Matthiessen’s rule显示文摘Dislocations can greatly enhance the figure of merit of thermoelectric materials by prominently reducing thermal conductivity.However,the evolution of phonon modes with different energies when they propagate through a single dislocation is unknown.Here we perform non-equilibrium molecular dynamics simulation to study phonon transport in PbTe crystal with dislocations by excluding boundary scattering and strain coupling effect.The frequency-dependent heat flux,phonon mode analysis,and frequency-dependent phonon mean free paths(MFPs)are presented.The thermal conductivity of PbTe with dislocation density on the order of 10^(15)m^(−2) is decreased by 62%.We provide solid evidence of strong localization of phonon modes in dislocation sample.Moreover,by comparing the frequency-dependent phonon MFPs between atomistic modeling and traditional theory,it is found that the conventional theories are inadequate to describe the phonon behavior throughout the full phonon spectrum,and large deviation to the well-known semi-classical Matthiessen’s rule is observed.These results provide insightful guidance for the development of PbTe based thermoelectrics and shed light on new routes for enhancing the performance of existing thermoelectrics by incorporating dislocations.Yandong Sun Yanguang Zhou Jian Han Wei Liu Cewen Nan Yuanhua Lin Ming Hu Ben Xu 2019npj Computational Materials2019,,1:1

10Highly Thermo-Conductive Three-Dimensional Graphene Aqueous Medium显示文摘Highly thermo-conductive aqueous medium is a crucial premise to demonstrate high-performance thermal-related applications.Graphene has the diamond comparable thermal conductivity,while the intrinsic two-dimensional reality will result in strong anisotropic thermal conductivity and wrinkles or even crumples that significantly sacrifices its inherent properties in practical applications.One strategy to overcome this is to use three-dimensional(3D)architecture of graphene.Herein,3D graphene structure with covalent-bonding nanofins(3D-GS-CBF)is proposed,which is then used as the filler to demonstrate effective aqueous medium.The thermal conductivity and thermal conductivity enhancement efficiency of 3D-GS-CBF(0.26 vol%)aqueous medium can be as high as 2.61 W m-1 K-1 and 1300%,respectively,around six times larger than highest value of the existed aqueous mediums.Meanwhile,3D-GS-CBF can be stable in the solution even after 6 months,addressing the instability issues of conventional graphene networks.A multiscale modeling including non-equilibrium molecular dynamics simulations and heat conduction model is applied to interpret experimental results.3D-GS-CBF aqueous medium can largely improve the solar vapor evaporation rate(by 1.5 times)that are even comparable to the interfacial heating system;meanwhile,its cooling performance is also superior to commercial coolant in thermal management applications.Zheng Bo Chongyan Ying Huachao Yang Shenghao Wu Jinyuan Yang Jing Kong Shiling Yang Yanguang Zhou Jianhua Yan Kefa Cen 2020Nano-Micro Letters2020,12,10:1

13High‐performance and wide relative humidity passive evaporative cooling utilizing atmospheric water显示文摘Global warming and increased living standards have rapidly increased the demand for cooling systems.Meeting this demand in less economically developed areas is highly challenging due to a lack of electricity.In this paper,we have demonstrated a high‐performance and wide relative humidity(RH)solar‐driven evaporative cooling strategy that uses only atmospheric water.Developed here for the first time,we designed a metal–organic framework(MOF‐801)based composite with a high‐performance atmospheric water absorption across a wide range of RH.The as‐synthesized composite can adsorb atmospheric water up to~22%(~80%)of its weight at an RH@28%(~70%).Our demonstration has shown that the corresponding cooling powers range from 136 to 344 W/m2 in a wide range of RH and solar intensities,and the passive cooling temperature is up to 14°C lower than the device's reference counterpart.Our study thus proposes a solar‐driven cooling coating with high cooling powers across a wide range of RH based on an as‐synthesized composite,which pinpoints a pathway to replace traditional compression‐based cooling systems(e.g.,air conditioners)and which will also have a significant impact in future global energy consumption.Guang Wang Yang Li Huihe Qiu He Yan Yanguang Zhou 2023Droplet2023,2,1:1

15Absolute sea level variability of Arctic Ocean in 1993–2018 from satellite altimetry and tide gauge observations显示文摘Arctic absolute sea level variations were analyzed based on multi-mission satellite altimetry data and tide gauge observations for the period of 1993–2018.The range of linear absolute sea level trends were found-2.00 mm/a to 6.88 mm/a excluding the central Arctic,positive trend rates were predominantly located in shallow water and coastal areas,and negative rates were located in high-latitude areas and Baffin Bay.Satellite-derived results show that the average secular absolute sea level trend was(2.53±0.42)mm/a in the Arctic region.Large differences were presented between satellite-derived and tide gauge results,which are mainly due to low satellite data coverage,uncertainties in tidal height processing and vertical land movement(VLM).The VLM rates at 11 global navigation satellite system stations around the Arctic Ocean were analyzed,among which 6 stations were tide gauge colocated,the results indicate that the absolute sea level trends after VLM corrected were of the same magnitude as satellite altimetry results.Accurately calculating VLM is the primary uncertainty in interpreting tide gauge measurements such that differences between tide gauge and satellite altimetry data are attributable generally to VLM.Yanguang Fu Yikai Feng Dongxu Zhou Xinghua Zhou 2021Acta Oceanologica Sinica2021,40,10:0
16Contributions of annual and semiannual tidal constituents to chart datum in the China seas and adjacent waters显示文摘Global uniform chart datum(CD)surface construction is the basic upon which to realize various vertical datums transformation,and is of great importance for geospatial data expression under the same vertical datum.Generally,the CD level is computed by developing the function between tidal constituents’harmonic constants and time,i.e.,the lowest astronomical tide is taken as the lowest predicted tide level by adopting the major constituents over a 19-a period.The CD surface prescribed in China is the theoretical lowest tide(TLT)and is calculated using 13 tidal constituents,i.e.,short-period(Q_(1),O_(1),P_(1),K_(1),N_(2),M_(2),S_(2),K_(2),M_(4),MS_(4)and M_(6))and long-period(Sa and Ssa)tidal constituents.Although the accuracy in determining short-period tidal constituents has improved gradually,the long-period tide has not been studied thoroughly owing to nonstationary and temporal variations.Previous studies have intended to evaluate the effect of Sa and Ssa tides in the determination of the TLT level for the purpose of determining a more accurate CD surface for the China seas and adjacent waters.Here,the parameters of long-period tidal correction and long-period tidal correction rate were treated as the effect of both Sa and Ssa on the TLT,and the TOPEX/Poseidon and Jason series satellite altimetry data ranged from October 1992 to April 2022 were adopted to analyze the contribution of long-period tidal constituents.Results showed that the average long-period correction value is 10.10 cm(range from 8.57 cm to 14.98 cm),and that the average long-period tidal contribution rate is 14.56%(range from 9.09%to 23.97%)in the China seas and adjacent waters.Finally,data from 82 tide gauge station with at least a 1-a record of hourly observations were compared with satellite-derived result.We concluded that the long-period tidal contribution should not be neglected in TLT construction.Furthermore,to reduce tidal datum uncertainty,accurate extraction of long-period tidal constituents should receive closer attentions.Yikai Feng Yanguang Fu Long Yang Dongxu Zhou 2023Acta Oceanologica Sinica2023,42,10:0
