摘要:Lithium-ion battery formation is a pivotal step that dictates performance, longevity, and manufacturing safety. At the core of this process is the formation and evolution of the solid electrolyte interphase (SEI), whose nanoscale thickness, high environmental sensitivity, and dynamic behavior have long hindered direct characterization. Here, we exploit the SEI-induced refractive index matching effect and utilize operando optical microscopy to directly visualize SEI growth in real time. Our obs...

摘要:Despite their ubiquity in Nature, spikes or stingers rarely exhibit sharp tips. Instead, a closer inspection of their roughly conical tips reveals a striking similarity in their profiles: They adhere to a power-law, z similar to rn, where n approximate to 2. This conformity persists across diverse spatial scales and materials. The mechanistic basis for this universality was recently attributed to evolutionary selection for ease of piercing [H. Quan et al., Proc. Natl. Acad. Sci. U.S.A. 121, e2...

摘要:Precipitation influences animal physiology, behavior, and ecological interactions, therefore affecting demography. However, the nature and strength of those effects vary widely, have been attributed to mechanisms operating over different time scales, and may depend on species-level attributes. We conducted a global meta-analysis accounting for shared evolutionary history to a) understand the nature of relationships between precipitation and avian reproductive success and b) test alternative hy...
