Universality of periodicity as revealed from interlayer-mediated cracks

Abstract: A crack and its propagation is a challenging multiscale materials phenomenon of broad interest, from nanoscience to exogeology. Particularly in fracture mechanics, periodicities are of high scientific interest. However, a full understanding of this phenomenon across various physical scales is lacking. Here, we demonstrate periodic interlayer-mediated thin film crack propagation and discuss the governing conditions resulting in their periodicity as being universal. We show strong confinement of thin film cracks… Show more

“…The Co 3 O 4 NFs@rGO flexible electrode showed a high reversible capacity of 615 mAh g À1 , excellent rate capability, and 92% capacity retention after 400 cycles at 4.0 A g À1 . [111] As one of the alternative candidates for the widely studied lithiumion batteries, sodium-ion batteries are more promising for large-scale applications due to the natural abundance and much lower cost of sodium. Compared with lithium ion, sodium ion needs more space for motion intercalation, because of its larger radius.…”

“…However, the performance of such conversion anodes is limited by several factors, including low electronic conductivity, structural instability, slow Li + diffusion, and slow reaction kinetics . Previously reported methods to address these issues to include (i) nanosizing the active material, (ii) applying coatings (e.g., carbon coatings), (iii) doping with foreign materials (e.g., nitrogen, sulfur), and (iv) optimizing the conductive carbon and polymer binder used in composite anodes …”
