Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Dopant Distribution in Ga‐Implanted CdO—A Correlative Microscopy and Molecular Dynamics Study

Advanced Functional Materials, EarlyView.
This work demonstrates that ion implantation offset angle could modulate carrier concentration and mobility in cadmium oxide thin films. Combining correlative microscopy workflow and molecular dynamics simulations, this study reveals the control of interfacial cluster density with tailoring implantation angles, and the optimum offset angle that ...

First experimental constraint of the spectroscopic amplitudes for the -cluster in the B ground state

Physics Letters, 2019
We present the first experimental determination on the spectroscopic amplitudes (SAs) for the α-cluster in the B11 ground state via the Li7(Li6,d)11B reaction using a high-precision magnetic spectrograph. This is believed to have a strong effect on the studies of α-induced reactions which are crucial in nuclear astrophysics.

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).
