| 1 | Carbon sequestration in biomass and soil following reforestation:a case study of the Yangtze River Basin显示文摘The effect of reforestation on carbon sequestration has been extensively studied but there is less understanding of the changes that stand age and vegetation types have on changes in biomass carbon and soil organic carbon(SOC)after reforestation.In this study,150 reforested plots were sampled across six provinces and one municipality in the Yangtze River Basin(YRB)during 2017 and 2018 to estimate carbon storage in biomass and soil.The results illustrate that site-averaged SOC was greater than site-averaged biomass carbon.There was more carbon sequestered in the biomass than in the soil.Biomass carbon accumulated rapidly in the initial 20 years after planting.In contrast,SOC sequestration increased rapidly after 20 years.In addition,evergreen species had higher carbon density in both biomass and soil than deciduous species and economic species(fruit trees).Carbon sequestration in evergreen and deciduous species is greater than in economic species.Our findings provide new evidence on the divergent responses of biomass and soil to carbon sequestration after reforestation with respect to stand ages and vegetation types.This study provides relevant information for ecosystem management as well as for carbon sequestration and global climate change policies. | Jianyu Wang Claudio O.Delang Guolong Hou Lei Gao Xiankun Yang Xixi Lu | 2022 | Journal of Forestry Research2022，33，5： | 1 |
| 2 | Sodium-based dual-ion batteries via coupling high-capacity selenium/graphene anode with high-voltage graphite cathode显示文摘Dual ion batteries(DIBs) exhibit broad application prospects in the field of electrical energy storage(EES)devices with excellent properties,such as high voltage,high energy density,and low cost.In the graphitebased DIBs,high voltage is needed to store enough anions with the formation of anion intercalation compound XCn(X=AlCl4-,PF6-,TFSI-,etc.).Hence,it is difficult for graphite-based DIBs to match proper anodes and electrolytes.Here,an Se/graphene composite is prepared via a convenient method,and assembled into a dual-ion full battery(DIFB) as anode with graphite cathode and 1 mol/L NaPF6 in EC:EMC(1:1,v:v).This DIFB has achieved a high discharge capacity of 75.9 mAh/g and high medium output voltage of 3.5 V at 0.1 A/g.Actually,the suitable anode materials,such as the present Se/graphene composite,are extremely important for the development and application of graphite-based DIBs.This study is enlightening for the design of future low-cost EES devices including graphite-based DIBs. | Xiankun Hou Wenhao Li Yingying Wang Shaofang Li Yunfeng Meng Haiyue Yu Baokuan Chen Xinglong Wu | 2020 | Chinese Chemical Letters2020，31，9： | 1 |
