Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

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.

Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...

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

Self‐organized Criticality in Neuromorphic Nanowire Networks With Tunable and Local Dynamics
Memristive nanowire networks (NWNs) are shown to be electrically tunable to a critical state where specific local dynamics evaluated by multiterminal characterization are exploited as feature selection in nonlinear transformation (NLT) tasks.
