DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

open access: yesAdvanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

open access: yesAdvanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Magnetic‐Field Dependent VB− Spin Decoherence in Hexagonal Boron Nitrides: A First‐Principles Study

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the decoherence of the VB− defect in h‐BN under external magnetic fields using first‐principles quantum many‐body simulations. A transition boundary distinguishing distinct decoherence regimes is identified, with its dependence on isotopic composition.

2D Phosphorene‐Decorated Ni‐Rich Layered Cathodes for High‐Power and High‐Energy Li‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A conformal coating of 2D phosphorene nanosheets is decorated on Li[Ni0.8Co0.1Mn0.1]O2 cathodes to enhance fast charge–discharge performance and structural stability under high mass loading and low carbon content. As a result, it exhibits improved power capability, cycle stability, and suppressed structural degradation, offering a promising strategy ...

Fermi Surface Nesting and Anomalous Hall Effect in Magnetically Frustrated Mn2PdIn

open access: yesAdvanced Functional Materials, EarlyView.
Mn2PdIn, a frustrated inverse Heusler alloy, showing electronic‐structure driven anomalous Hall effect with Weyl crossings, Fermi‐surface nesting and near‐zero magnetization ideal for low‐magnetization spintronics. Abstract Noncollinear magnets with near‐zero net magnetization and nontrivial bulk electronic topology hold significant promise for ...

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

open access: yesAdvanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...
