The reflection and refraction of a curved shock front sliding over an air–water interface
, 2022 The present study aims to investigate the reflection and refraction of a curved shock front as it slides along an air–water interface, using the time-resolved shadowgraph technique. The curved shock front is generated from a free-piston shock tube.

Helicity‐Defined Analog Conductance States in Chiral Perovskite Synapses
Advanced Materials, EarlyView.Chiral perovskite synapses convert the handedness of circularly polarized light into persistent analog memory during electrical programming. An optimized n = 3 structure combines strong helicity selectivity with low read noise, enabling 72 distinct conductance levels.
