High Rate Capability and Cycling Stability in Multi‐Domain Nanocomposite LiNi1–xTi3x/4O2 Positive Electrodes

open access: yesAdvanced Materials, EarlyView.
By targeting nominally non‐stoichiometric LiNi1–xTi3x/4O2 compositions, a multi‐domain nanocomposite rock salt positive electrode material with exceptional cycling stability and excellent rate performance is obtained. This enhanced performance particularly under high oxidative potential protocols and cell electrode mass loadings applicable to ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

open access: yesAdvanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

open access: yesAdvanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Designing Maximal Strength in Nanolamellar Eutectic High‐Entropy Alloys

open access: yesAdvanced Materials, EarlyView.
This study uses molecular dynamics simulations to guide the design of EHEAs with superior mechanical performance. The simulations reveal a peak tensile strength at a critical interphase boundary spacing. Below this spacing, the governing mechanism shifts from the Hall–Petch strengthening to dislocation multiplication–mediated softening. Guided by these

Unraveling the Complexity of the Dzyaloshinskii–Moriya Interaction in Layered Magnets: The Full Magnitude and Chirality Control

open access: yesAdvanced Materials, EarlyView.
In layered magnets, the atomistic Dzyaloshinskii–Moriya interaction (DMI) depends critically not only on the orbital occupancy of the interface layer but also on the sequence of the atomic layers. The effect can be understood by analyzing the contributions of different orbitals to DMI.
