Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Enhanced Ferroelectric Properties of MoS2-Capped HZO Thin Films Induced by Thermal Mismatch Stress

Hf0.5Zr0.5O2 (HZO) is a promising material for applications to ferroelectric (FE) nanoscale devices, such as FE random access memory (FeRAM) and FE field effect transistor (FeFET), due to its down-scaling capability and CMOS compatibility.

Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

Advanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.

Photoelectric‐Coupled Ferroelectric Heterojunctions for Ultrahigh NO2 Sensing With Polarization‐Memory‐Assisted Interfacial Modulation

Advanced Science, Volume 13, Issue 49, 3 September 2026.
This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...
