Investigating Experimental Short Term Imprint Dynamics in Ferroelectric Hafnium Oxide Through Phase‐Field Modeling

Advanced Functional Materials, EarlyView.
Phase‐field modeling reveals the mechanisms behind short‐term ferroelectric imprint in Hf0.5Zr0.5O2 polycrystalline thin films. Combined with a charge trapping model, the proposed framework accurately reproduces coercive field shifts with pause time and their recovery through field cycling in polarization‐voltage measurements, offering valuable ...

Quantum‐Grade Nanodiamonds from a Single‐Step, Industrial‐Scale Pressure and Temperature Process

Advanced Functional Materials, EarlyView.
Novel method for creation of nitrogen‐vacancy centers in 50‐nm nanodiamonds based on high‐temperature plastic deformation is demonstrated. Compared to the electron irradiation approach, it yields nitrogen‐vacancy centers with significantly improved charge stability, T1 relaxation time, and optical Rabi contrast.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Circularly Polarized Light Emission From Single Chiral Hedgehog Particles Coated with Nanofilms of Achiral Perovskites

Advanced Materials, EarlyView.
Left‐ and right‐handed circularly polarized light emission (CPLE) is observed from chiral “hedgehog” particles (CHIPs) coated with a nanofilm of achiral perovskite, with spectroscopic bands specific to the perovskites and chirality specific to the template CHIPs. Careful analysis of optical activity indicates that the CPLE of perovskite luminescence is

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

Advanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Carrier Diffusion Links Single Crystal Quality and Photoluminescence in Halide Perovskite Radiation Detectors

Advanced Materials, EarlyView.
By tracking bulk carrier diffusion both vertically and laterally, this study links photoluminescence behavior to crystal quality in CsPbBr3 γ‐ray detectors. Vertical diffusion governs spectral redshift, with high‐quality crystals exhibiting superior transport, while two‐photon microscopy reveals microscale defects that hinder diffusion in low‐quality ...
