Growth of tin hillock and whisker under harmonic power conditions in tin-plated copper busbars for power system

open access: yesJournal of Materials Research and Technology
Tin hillock and whisker growth pose a serious reliability concern in tin-coated copper busbars, particularly in lead-free systems subjected to dynamic electrical environments. In this study, the influence of harmonic current stress on hillock and whisker

Targeting IL27RA Enhances Immunotherapy in Triple‐Negative Breast Cancer by Modulating Tumor Cells and the Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
IL27RA upregulation drives immune evasion in TNBC by suppressing MHC‐I expression and reprogramming T/NK‐cell states, establishing an immune‐excluded tumor phenotype. Targeting this epithelial‐intrinsic IL27RA–PI3K/AKT axis offers a promising strategy to overcome immunotherapy resistance.

Iron/Cobalt Dual‐Atom Catalyst Orchestrate Photothermal‐Chemodynamic Immunotherapy Against MRSA: Multi‐Omics Dissection in Murine and Porcine Models

open access: yesAdvanced Science, EarlyView.
FeCo dual‐atom catalyst (FeCo‐N‐DAC) with ultrahigh metal loading (Fe > 5.4%, Co > 4.8%) is developed for synergistic photothermal‐chemodynamic immunotherapy. FeCo‐N‐DAC penetrates deep‐seated tissues, eradicates MRSA biofilms, and reprograms immune‐inflammatory pathways via multi‐omics‐validated mechanisms.

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

open access: yesAdvanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Dual‐Modulated Vertically Stacked Transistors With Fully Laminated Plate‐Type Architecture Featuring Nanoscale Channel Length

open access: yesAdvanced Science, EarlyView.
A new vertical transistor design with a dual‐modulation strategy is proposed to overcome the limitations of conventional transistors. This architecture uses a micro‐hole patterned electrode and a graphene electrode to enhance channel control and incorporates a leakage blocking layer to suppress off‐state current.

Elimination of Low-Angle Grain Boundary Networks in FeCrAl Alloys with the Electron Wind Force at a Low Temperature

open access: yesMetals
Low-angle grain boundaries (LAGBs) accommodate residual stress through the rearrangement and accumulation of dislocations during cold rolling. This study presents an electron wind force-based annealing approach to recover cold-rolling induced residual ...

The effect of vibratory stress on the welding microstructure and residual stress distribution [PDF]

open access: yes, 2001
Previous studies have suggested that weld microstructure may be modified by the presence of static stresses. In this investigation, vibratory stress was applied to mild steel specimens while they were being welded to observe its effect on the residual ...

Schwann Cell Synthesized Cholesterol Orchestrates Peripheral Nerve Regeneration via Structural and IGF1‐Dependent Signaling Mechanisms

open access: yesAdvanced Science, EarlyView.
This study reveals that Schwann cell FDFT1‐mediated cholesterol synthesis is essential for peripheral nerve regeneration via dual roles: as a structural component for myelin and as a metabolic signal that upregulates IGF1. IGF1 promotes axonal growth through paracrine action and enhances Schwann cell differentiation/ myelination via an intrinsic IGF1R ...
