Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, EarlyView.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Entropy‐Driven Spin Transition in Rare Earth Perovskites Enables Feedback Adsorption for Enhanced Acidic Water Oxidation

open access: yesAdvanced Materials, EarlyView.
A synthetic protocol for fabricating high‐entropy rare earth perovskite oxides with abundant lattice distortions and oxygen vacancies has been developed, representing an emerging platform for anchoring RuO2. High entropy strategy significantly modulated the electronic structures and spin states, inducing a shift in the mechanism from the adsorption ...

Rutile Without Substrate Limitations: Top‐Interface‐Driven Crystallization of TiO2

open access: yesAdvanced Materials, EarlyView.
A RuO2 upper layer acts as a removable crystallization template that triggers rutile TiO2 formation from the top interface, independent of the underlying substrate. This top‐interface‐driven crystallization mechanism enables rutile growth even on amorphous ZrO2/TiN, offering a substrate‐agnostic route to high‐k dielectrics compatible with DRAM process ...

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...
