Leveraging Atomic Disorder to Modulate Hydrogen Storage Thermodynamics in Intermetallics

Interdisciplinary Materials, EarlyView.
This work introduces atomic disorder into TiFe‐based intermetallics through multi‐element substitution to tune hydrogen storage properties. A series of B2‐structured, compositionally complex intermetallics are synthesized and evaluated, revealing that increased atomic disorder enhances hydride stability.

Reactive selenium induced near‐surface reconstruction to stabilize high‐voltage, cobalt‐free cathodes for high‐rate, long‐cycling lithium batteries

InfoMat, EarlyView.
To address the challenges of structural degradation and side reactions with the electrolyte during cycling for spinel LNMO cathode, we propose a reactive Se‐induced near‐surface reconstruction strategy, integrating SeOx coating and Se doping into the near‐surface of LNMO via a one‐step selenization process.

Conjugation‐mediated and polarity‐switchable interfacial layers for fast cycling of lithium‐metal batteries

InfoMat, EarlyView.
Thiophene‐embedded solid electrolyte interphase exhibits switchable polarity for uniform Li plating, and the electron‐rich cathode electrolyte interphase stabilizes high‐valence Ni ions in the cathode. These molecularly engineered interfacial layers enable fast cycling of lithium‐metal batteries for practical applications.

Dark-field Brillouin microscopy

Optics Letters, 2017
Brillouin microscopy is a non-contact and label-free technique for mapping fundamental micro-mechanical properties in the volume of biological systems. Specular reflections and elastic scattering easily overwhelm the weak Brillouin spectra due to the limited extinction of virtually imaged phased array spectrometers, thereby affecting the image ...
