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

open access: yesAdvanced 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.

Self‐Assembly Hypoxic and ROS Dual Response Nano Prodrug as a New Therapeutic Approach for Glaucoma Treatments

open access: yesAdvanced Science
Glaucoma is an irreversible blinding eye disease characterized by retinal ganglion cell (RGC) death.Previous studies have demonstrated that protecting mitochondria and activating the CaMKII/CREB signaling pathway can effectively protect RGC and axon ...

Coumarin Reduces Aluminum-Induced Inhibition of Growth and Photosynthesis in Citrus grandis by Reducing Tissue Al Concentration and Maintaining Nutrient and Redox Homeostasis

open access: yesPlants
No data to date are available on the underlying mechanisms by which coumarin (COU) alleviates plant aluminum (Al) toxicity. Citrus grandis (L.) Osbeck seedlings were submitted to 0 (Al0) or 1.2 (Al1.2 or Al3+ toxicity) mM AlCl3·6H2O and 0 (COU0) or 50 ...

Modulating Calcium Homeostasis via a Biomimetic Scaffold to Rescue Diabetic Ischemic Wounds

open access: yesAdvanced Science, EarlyView.
This strategy addresses impaired microcirculation and loss of extracellular matrix (ECM) guidance in diabetic wound healing. Musc@CP, a nanofibrous dressing combining an ECM‐mimetic chitosan‐pullulan scaffold with muscone, enhances perfusion by attenuating intracellular Ca2+ overload‐associated endothelial dysfunction.

A High‐Loading Zn Single‐Atom Nanozyme Targets the Zn/HIF‐1α/GLUT1 Axis to Disrupt Glucose Metabolic Reprogramming and Remodel the Tumor Immune Microenvironment

open access: yesAdvanced Science, EarlyView.
A high‐loading Zn single‐atom nanozyme (ZMG@CS) delivers ML‐SA5 and GOx to lysosomes. ML‐SA5 activates TRPML1 to release endogenous Zn2+, while the nanozyme provides exogenous Zn2+ and GOx‐driven acidification amplifies ROS production. Together, these effects suppress the HIF‐1α/GLUT1 axis, disrupt glucose and redox homeostasis, induce disulfidptosis ...

Asymmetric Single‐Atom Catalysts Govern Diffusible and Non‐Diffusible Non‐Radical Pathways for Selective Degradation of Antibiotic Resistance Genes

open access: yesAdvanced Science, EarlyView.
Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.
