Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors
Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...
