Abstract. Plant carbon (C) content is one of the most important plant traits and critical to assessment global C cycle ecological stoichiometry; however, variations in remain poorly understood. In this study, we conducted a analysis by synthesizing data from 4318 species document specific values their variation across organs life forms. organ contents ranged 45.0 % reproductive 47.9 stems at scales, which were significantly lower than widely employed canonical value 50 %. leaves (global mean...
Abstract In situ weaving an all‐carbon graphdiyne coat on a silicon anode is scalably realized under ultralow temperature (25 °C). This economical strategy not only constructs 3D mechanical and conductive networks with reasonable voids for the at one time but also simultaneously forms robust interfacial contact among electrode components. The intractable problems of disintegrations in caused by repeated volume variations during cycling are effectively restrained. as‐prepared demostrates...
