Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Clustered Ca2+ Channels Are Blocked by Synaptic Vesicle Proton Release at Mammalian Auditory Ribbon Synapses

open access: yesCell Reports, 2018
Summary: A Ca2+ current transient block (ICaTB) by protons occurs at some ribbon-type synapses after exocytosis, but this has not been observed at mammalian hair cells.
