1北美和欧洲树线:影响其位置的外部因子和内在过程显示文摘本文对过去所提出的控制欧洲和北美树线位置的因子和植物过程进行了评价。有人认为是由于环境灾害造成的,另一种则认为是树木物质递增受到限制造成的,实际上二者是相辅相成的。这是因为植物所受的伤害、加之物质获取的不利条件及较少的可用物质源最终会导致生物量增加难以维持,而并非立刻死亡。树线达到平衡的位置随气候而变化,但灾难性的事件和人类活动削弱了树线与气候的相关关系,增加了预测其将来位置的难度。在树线或树线以下的多个地理位置开展多树种条件下的野外调控实验对总结解释和预测的一般结论是必须的。Bjartmar Sveinbjrnsson 石培礼 2000AMBIO-人类环境杂志2000,29,7:3

16Demonstration of no catalytical activity of Fe-N-C and Nb-N-C electrocatalysts toward nitrogen reduction using in-line quantification显示文摘Ammonia(NH3)production via the electrochemical nitrogen reduction reaction(NRR)is a promising method for sustainable generation of this important chemical.Efforts are ongoing in finding an efficient,stable,and selective catalyst that will enable the reaction.However,progress is hindered in the field due to lack of reproducibility,most likely a consequence of reports of false-positive results due to improper measurement control and methods.In this study,we explore the NRR activity of a promising class of single atom catalysts,transition metal-nitrogen-carbon(M-N-C)electrocatalysts.Using a state-of-the-art in-line ammonia quantification methodology,with detection limit as low as 1 ppb for ammonia,we show that single atom Nb and Fe embedded in a stable carbon and nitrogen framework do not electrochemically reduce N_(2) to NH_(3).Critically,this demonstrates that our experimental setup with in-line sequential injection analysis successfully excludes ammonia contamination from the gas supply and atmospheric sources,allowing for thorough and high-throughput examination of potential NRR catalysts.Arnar Sveinbjörnsson Anna Bergljót Gunnarsdóttir Erin B.Creel Camila Pía Canales Barr Zulevi Xiang Lyu Charl J.Jafta Egill Skúlason Alexey Serov Helga Dögg Flosadóttir 2022SusMat2022,2,4:0
