Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

open access: yesAdvanced Functional Materials, EarlyView.
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 ...

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

open access: yesAdvanced Functional Materials, EarlyView.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Shape‐Reconfigurable Crack‐Based Strain Sensor with Ultrahigh and Tunable Sensitivity

open access: yesAdvanced Functional Materials, EarlyView.
A highly sensitive crack‐based sensor with tunable strain detection capabilities is demonstrated through controlled nanocrack formation in a line‐patterned shape memory polymer substrate. The sensor design integrates thermoplastic polyurethane and poly(lactic acid), enabling thermo‐responsive reconfiguration of crack geometry.

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption

open access: yesAdvanced Functional Materials, EarlyView.
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.
