Tunable Infrared Emissivity Using Laser‐Sintered Liquid Metal Nanoparticle Films

Advanced Functional Materials, EarlyView.
This paper reports a decrease in the IR emissivity of liquid metal particle films after laser exposure. It is concluded that the decrease in IR emissivity is not due to changes in the film's topography but rather to sub‐surface sintering of the particles. This phenomenon enables encrypting messages and camouflaging laser‐processed patterns.

Synergistic Effects of Ruthenium and Zinc Active Sites Fine Tune the Electronic Structures of Augmented Electrocatalysis

Advanced Functional Materials, EarlyView.
This study presents an electronic fine‐tuning (EFT) strategy to optimize the electronic structures of Ru species and single‐atom Zn sites by the virtue of layered nanosheets, significantly enhancing ORR and HER activities. Spectroscopic analysis and theoretical calculations uncover that this EFT effect breaks the ORR scaling limitation and positions ...

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide

Advanced Functional Materials, EarlyView.
The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Distinctive Doping Behavior of Conjugated Polymers With Pendant‐Side Conjugation for Enhanced Thermoelectric Properties

Advanced Functional Materials, EarlyView.
Novel conjugated polymers with side‐chain π‐conjugation are developed to enhance organic thermoelectric properties. Remarkably, the pendant doping in the conjugated polymers preserved strong intermolecular ordering in the film states even at high FeCl3 dopant concentrations (16 – 32 mM), achieving a promising power factor > 10 µW m−1 K−2 across a wide ...

Artificial Modulation of the Hydrogen Evolution Reaction Kinetics via Control of Grain Boundaries Density in Mo2C Through Laser Processing

Advanced Functional Materials, EarlyView.
A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.
