Sonochemical Functionalization of Glass

Advanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking

Advanced Functional Materials, EarlyView.
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...

Effects of Chemical Pressure on Superconductivity in Electrochemically Intercalated (TMA)yFe2(Se1−xSx)2 (TMA = Tetramethylammonium)

Advanced Functional Materials, EarlyView.
Intercalation of a series of FeSe1−xSx host crystals with tetramethylammonium cations (TMA+) linearly scales the critical temperature Tc from 43 K down to 28 K with increasing sulfur incorporation. The chemical pressure induced by the partial substitution shows a weakening of the superconducting properties in both hosts and intercalates in a remarkably

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films

Advanced Functional Materials, EarlyView.
Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...

Polymer Brush Growth by Surface‐Initiated Ring‐Opening Polymerization from a Cross‐Linked Polymer Thin Film

Advanced Functional Materials, EarlyView.
A stable cross‐linked ultra‐thin polymer coating for surface‐initiated ring‐opening polymerization (SI‐ROP) of hexamethylcyclotrisiloxane and ε‐caprolactone for growth of high grafting density poly(dimethyl siloxane) and poly(caprolactone) brushes is developed.

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

Advanced 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 ...

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

Advanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

Advanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for
