A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance

Advanced Functional Materials, EarlyView.
The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device

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.

Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3

Advanced Functional Materials, EarlyView.
Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

Advanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.
