Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

open access: yesSmall, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

AI‐enabled engineering of hesperidin/ursodeoxycholic acid nanomedicine for synergistic treatment of drug‐induced liver injury

open access: yesSmart Molecules, EarlyView.
An AI‐driven framework integrating disease‐network analysis, direction‐aware molecular screening, and carrier‐free co‐assembly engineering enables nanomedicine design. The dual‐constraint deep learning model predicts API–target affinity and regulatory direction to prioritize complementary APIs.

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

The Unintended Consequences of German Deterrence

open access: yesGlobal Policy, EarlyView.
ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.
