Abstract The blocking of ion transport at interfaces strongly limits the performance electrochemical nanodevices for energy applications. barrier is believed to arise from space-charge regions generated by mobile ions analogy semiconductor junctions. Here we show that something different play studying in a bicrystal yttria (9% mol) stabilized zirconia (YSZ), an emblematic oxide conductor. Aberration-corrected scanning transmission electron microscopy (STEM) provides structure and composition...

The discovery that the propensity for particle motion in a supercooled liquid is completely determined by initial structure pointed to existence of causal link between and dynamics glassy systems. Here we demonstrate this underlying influence only local time, fading out beyond metabasin lifetime much before $\ensuremath{\alpha}$ relaxation time. Thus, our results reveal irreproducibility support scenario random walk on metabasins long time diffusion.

Soluble proteins must maintain backbone hydrogen bonds (BHBs) water-tight to ensure structural integrity. This protection is often achieved by burying the BHBs or wrapping them through intermolecular associations. On other hand, water has low coordination resilience, with loss of hydrogen-bonding partnerships carrying significant thermodynamic cost. Thus, a core problem in biology whether natural design actually exploits stiffness seal regions that are exposed solvent. work explores...
