Na metal batteries (NMBs) are attracting increasing attention because of their high energy density. However, the widespread application of NMBs is hindered by the growth of Na dendrites and interface instability. The design of artificial solid electrolyte interphase (SEI) with tuned chemical/electrochemical/mechanical properties is the key to achieving high-performance NMBs.

Unlabelled: In the Sichuan Basin, seismic activity has been low historically, but in the past few decades, a series of moderate to strong earthquakes have occurred. Especially since 2015, earthquake activity has seen an unprecedented continuous growth trend, and the magnitude of events is increasing. Following the 5.

Multiple lines of evidence, including an epidemic-type aftershock sequence model, relocated hypocenters, the mechanisms of 13 large events (M > 3.5), and numerically calculated Coulomb failure stress results, convincingly suggest that a series of earthquakes with moment magnitudes up to M 4.

Objective: To investigate the blood vascular distribution of supra-genicular flap and to apply the retrograded supra-genicular flap for reconstructive surgery.
Methods: Eight fresh adult cadavers with 16 lower extremities were used for the study, by means of injecting the media of red latex into the main artery of the limb. The skin vascular architecture on the lower two thirds of each thigh was observed to decide the blood supply of this region.
