Investigation on the Thermal Characteristics of 33-kV DC Vacuum Circuit Breakers Using 3-D Modeling

IEEE Access
In this article, a 3D model is used to investigate the thermal performance of the 33 kV Direct Current Vacuum Circuit Breakers (DCVCBs) when operating under normal current as well as under faulty conditions.

Interfacial Degradation Electrochemistry of Micro‐Silicon Anodes in Solid‐State and Liquid Electrolytes

Advanced Science, EarlyView.
This schematic compares m‐Si degradation in liquid electrolyte and solid electrolyte systems. In liquid electrolyte, repeated cycling induces severe particle pulverization and thick, unstable SEI growth. In contrast, the solid electrolyte configuration suppresses interfacial reactions, enabling a thin, stable SEI and improved structural integrity ...

Volatile ZrO2 Antiferroelectric Tunnel Junctions for Rapid, Energy‐Efficient Physical Reservoir Computing

Advanced Science, EarlyView.
An antiferroelectric tunnel junction serves as a reservoir computing node, where field‐induced phase transitions and spontaneous ZrO2 relaxation deliver nonlinear fading memory. An In‐Ga‐Zn oxide interlayer enlarges the memory margin and multibit state richness.

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

Advanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Partial Phase‐Separation in the Initial Growth Stage of Exsolution‐Active SrTi0.95‐xNi0.05NbxO3‐δ Thin Films

Advanced Science, EarlyView.
Phase separation emerges during the initial growth of heavily Ni‐ and Ni,Nb‐co‐doped STO thin films, leading to preferential accumulation of Ni and embedded NiOx nanoinclusions in thicker films. Nb co‐doping partially suppresses the ordering of these embedded structures, comprising about 20% of all Ni ions.

Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes

Advanced Science, EarlyView.
This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.

Overcoming Transmission Barriers: A Dual‐Functional Adhesive Hydrogel for Direct Monkeypox Virus Neutralization and Wound Healing

Advanced Science, EarlyView.
MPXV infection leads to persistent viral replication and severe local inflammation, while existing treatments cannot simultaneously remove viruses and repair injured tissue. This study constructs Polymer@mPDA@Gel hydrogel via a two‐step hierarchical assembly method: mPDA anchors photothermal polymers to form antiviral photothermal subunits, which are ...

Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR‐II Emission for Dynamic Deep‐Tissue Bioimaging

Advanced Science, EarlyView.
Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Plaque‐Hepatic Targeting Nanotherapy Disrupts the PCSK9‐LOX‐1 Axis to Suppress oxLDL in Atherosclerosis

Advanced Science, EarlyView.
Self‑amplifying PCSK9–LOX‑1 feedback axis drives atherosclerotic progression by promoting oxLDL generation and endothelial uptake. A dual‑targeting nanoplatform (siPCSK9@PEAL NPs‑aL) is constructed to simultaneously silence hepatic PCSK9 for lipid lowering and block plaque LOX‑1 for anti‑inflammation.
