1Social impacts of the climatic shift around the turn of the 19th century on the North China Plain显示文摘Historical case studies of climate change impacts and the resulting social responses can provide analogies for better understanding the impacts of current and future climate changes.Around the turn of the 19th century,the climate of the North China Plain experienced a shift from a relatively warm stage in the 18th century to a colder stage in the 19th century,which was characterised by a much colder climate and more frequent and severe floods and droughts.Historical information about refugees,social disorder,grain transportation,and disaster relief on the North China Plain in 1780-1819 is collected from the Veritable Records of the Qing Dynasty(a collection of official records).The mechanism of climate change affecting the food security of the society,as indicated by the development of a refugee problem around the turn of the 19th century,is analyzed by examining the social vulnerability.There are four basic findings:(1) In the 40 years from 1780-1819,the society on the North China Plain was unstable and characterised by a significant deterioration of the refugee situation.The number of refugees increased markedly,and their behaviour became increasingly violent.In the 1780s,most of the disaster victims chose to stay at their residences waiting for relief.From 1790 to 1800,hundreds of thousands of refugees migrated to northeast China.In the 1810s,the frequency of farmer rebellions increased sharply.(2) The increase in instability corresponded to the climatic cooling over the same time period.The increased instability was a result of the negative impacts of climate change accumulating and transmitting to the social level.(3) For food security,a precondition for the negative impacts of climate change on human society was the vulnerability of the regional socioeconomic system,which had a high sensitivity and low capacity to respond.This vulnerability could be described by the following three observations:① The regional balance of supply and demand for food was in a critical state,which led to a high sensitivity and dramatic reduction in yield that was caused by climate change;② the capacity for disaster relief efforts by the government was too low to meet the needs of crisis management;③ the capacity for refugees' resettlement in eastern Inner Mongolia and northeast China,which both border the North China Plain,was severely restricted by climatic conditions or the quarantine policy.(4) It is estimated that climate change caused the social vulnerability to reach a critical level approximately 20 years earlier on the North China Plain.FANG XiuQi XIAO LingBo WEI ZhuDeng 2013Science China Earth Sciences2013,56,6:19
2Isolation,purification and characterization of secondary structure of antifreeze protein from Ammopiptanthus mongo-licus显示文摘Antifreeze protein (AFP) from Ammopiptanthus mongolicus leaves was isolated and purified with DEAE cellulose 52, Sephacryl 300, heat treatment and preparative isotachophoresis. The molecular weight of AFP was 50 ku by SDS-PAGE measurement. The average thermal hysteresis activity (THA) of AFP was 0.35℃ at 5 mg/mL using a differential scanning calorimeter (DSC). This AFP showed heated stability. From circular dichroism (CD) of AFP spectral data from 195-240 nm, a well-defined secondary structure of 11% a-helix, 34% antiparallel β-sheet and 55% random coil for the plant AFP was deduced.FEI Yunbiao WEI Lingbo GAO Suqin LU Manchun WANG Baohuai LI Zhifen ZHANG Youming SHU Nianhong JIANG Yong WANG Weixiang 2001Chinese Science Bulletin2001,46,6:8
3Research progress on large-area perovskite thin films and solar modules显示文摘Organometal halide perovskites have exhibited a bright future as photovoltaic semiconductor in next generation solar cells due to their unique and promising physicochemical properties.Over the past few years,we have witnessed a tremendous progress of efficiency record evolution of perovskite solar cells(PSCs).Up to now,the highest efficiency record of PSCs has reached 22.1%;however,it was achieved at a very small device area of<0.1 cm^(2).With the device area increasing to mini-module scale,the efficiency record dropped dramatically.The inherent causes are mainly ascribed to inadequate quality control of large-area perovskite thin films and insufficient optimization of solar module design.In current stage of PSCs research and development,to overcome these two obstacles is in urgent need before this new technology could realize scale-up industrialization.Herein,we present an overview of recently developed strategies for preparing large-area perovskite thin films and perovskite solar modules(PSMs).At last,cost analysis and future application directions of PSMs have also been discussed.Zhichun Yang Shasha Zhang Lingbo Li Wei Chen 2017Journal of Materiomics2017,3,4:4
4Recent advances of flexible perovskite solar cells显示文摘In few years only, the efficiency record of perovskite solar cells(PSCs) has raised quickly from 3.8% to over 22%. This emerging photovoltaic technology has primarily shown its great potential of industrialization. Flexible PSCs are thought to be one of the most priority options for mass production, related to the intrinsic advantage of perovskite thin films which could be deposited by facile solution processes at low temperature. Flexible PSCs have at least four advantages in comparison to the rigid counterpart:(1) it can generate higher power output at lighter weight,(2) it is easily portable,(3) it can be easily attached to architectures or textiles with diverse shapes, and(4) it is compatible with roll-to-roll fabrication in a large scale. In this review, we have summarized recent development of the key materials and technologies applied in flexible PSCs. The key materials including flexible substrates, transparent and conductive electrodes, and interfacial materials; some key technologies about roll-to-roll manufacture, encapsulation technology have been overviewed. Finally, a prospect on possible application directions of flexible PSCs has been discussed.Lingbo Li Shasha Zhang Zhichun Yang Engamba Esso Samy Berthold Wei Chen 2018Journal of Energy Chemistry2018,27,3:3
5Cobalt hollow nanospheres: controlled synthesis, modification and highly catalytic performance for hydrolysis of ammonia borane显示文摘Size tunable cobalt hollow nanospheres with high catalytic activity for the ammonia borane(AB) hydrolysis have been synthesized by using the solvothermal method. The complexation between Co2+and ethylenediamine is observed to be critical for the formation of the cobalt hollow nanospherical structure.The morphology of the cobalt hollow nanospheres can be regulated by adjusting the original ethylenediamine/ethanol volume ratio, reaction time and temperature. Impressively, the magnetic property study reveals that the coercivity of the as-synthesized cobalt hollow nanospheres is much enhanced compared with that of bulk cobalt materials. Meanwhile, Co/Pt bimetal hollow nanospheres(Co Pt HS) and graphene-cobalt hollow composite nanospheres(Co HS-r GO) have also been explored. In comparison with the cobalt hollow nanospheres, both the Co Pt HS and Co HS-r GO show higher catalytic activities and better repeatability for the catalytic hydrogen generation from AB hydrolysis. Moreover, it is noted that these catalysts could be recycled by using the magnetic separation method.Wangya Wei Zumin Wang Jie xu Lingbo Zong Kun Zhao Hao Wang Haiyan Li Ranbo Yu 2017Science Bulletin2017,62,5:3
6An Ultra-microporous Carbon Material Boosting Integrated Capacitance for Cellulose-Based Supercapacitors显示文摘A breakthrough in advancing power density and stability of carbon-based supercapacitors is trapped by inefficient pore structures of electrode materials.Herein,an ultramicroporous carbon with ultrahigh integrated capacitance fabricated via one-step carbonization/activation of dense bacterial cellulose(BC)precursor followed by nitrogen/sulfur dual doping is reported.The microporous carbon possesses highly concentrated micropores(~2 nm)and a considerable amount of sub-micropores(<1 nm).The unique porous structure provides high specific surface area(1554 m^2 g^-1)and packing density(1.18 g cm^-3).The synergistic effects from the particular porous structure and optimal doping effectively enhance ion storage and ion/electron transport.As a result,the remarkable specific capacitances,including ultrahigh gravimetric and volumetric capacitances(430 F g^-1 and 507 F cm^-3 at 0.5 A g^-1),and excellent cycling and rate stability even at a high current density of 10 A g^-1(327 F g^-1 and 385 F cm^-3)are realized.Via compositing the porous carbon and BC skeleton,a robust all-solid-state cellulose-based supercapacitor presents super high areal energy density(~0.77 mWh cm^-2),volumetric energy density(~17.8 W L^-1),and excellent cyclic stability.Chenfeng Ding Tianyi Liu Xiaodong Yan Lingbo Huang Seungkon Ryu Jinle Lan Yunhua Yu Wei?Hong Zhong Xiaoping Yang 2020Nano-Micro Letters2020,12,5:2

12Spatial confinement of zeolitic imidazolate framework deposits by porous carbon nanospheres for dual-atom catalyst towards high-performance oxygen reduction reaction显示文摘Dual atom catalysts(DACs),are promising electrocatalysts for oxygen reduction reaction(ORR)on account of the potential dual-atom active sites for the optimized adsorption of catalytic intermediates and the lower reaction energy barriers.Herein,spatial confinement strategy to fabricate DACs with well-defined Fe,Co dual-atom active site is proposed by implanting zeolitic imidazolate frameworks inside the pores of highly porous carbon nanospheres(Fe/Co-SAs-Nx-PCNSs).The atomically dispersed dual-atom active sites facilitate the adsorption/desorption of intermediates.Furthermore,the spatial confinement effect protects metal atoms aggregating.Benefiting from the rich accessible dual-atom active sites and boosted mass transport,we achieve remarkable ORR performance with half-wave potential up to 0.91 and 0.8 V(vs.reversible hydrogen electrode(RHE)),and long-term stability up to 10 h in both alkaline and acidic electrolytes.The remarkably enhanced ORR catalytic property of our as-developed DACs is in the rank of excellence for 1%.The as-developed rechargeable Zn-air battery(ZAB)with Fe/Co-SAs-Nx-PCNSs air cathode delivers ultrahigh power density of 216 mW·cm^(−2),outstanding specific capacity of 813 mAh·g^(−1),and promising cycling operation durability over 160 h.The flexible Zn-air battery also exhibits excellent specific capacity,cycling stability,and flexibility performance.This work opens up a new pathway for the multiscale design of efficient electrocatalysts with atomically dispersed multiple active sites.Jiayi Zhao Ping Li Kaicai Fan Wenjie Wei Fenghong Lu Huimin Zhao Bin Li Lingbo Zong Lei Wang 2023Nano Research2023,16,8:0
