Hypoxic microenvironments arise when local oxygen supply fails to meet cellular demand and exert an influence on the progression of cancer, ischemic heart and brain injury, chronic inflammatory disorders, and other diseases. Conventional approaches, including oxygen delivery syst...

Electronic‐Structure Engineering Coordinates Na Nucleation Thermodynamics and Deposition Kinetics for Stable Sodium Metal Batteries

ABSTRACT Sodium metal batteries are limited by uncontrolled Na nucleation and nonuniform deposition, which originate from insufficient interfacial sodiophilicity and heterogeneous ion/electric‐field transport. Herein, we design a flexible lotus‐root‐like hierarchical porous carbo...

Real-time internal state estimation in composite photocuring via coupled heat-transfer modeling and Bayesian-optimized adaptive extended Kalman filtering

Ultraviolet (UV) photocuring of composite materials involves strongly coupled optical, thermal, and chemical processes, making transient internal temperature and degree of cure difficult to measure directly during processing. This study develops an online internal-state estimatio...

Improved low-temperature dehydrogenation kinetics and cyclic stability of Mg(NH2)2-2LiH catalyzed by K2TiF6 additive

Insight into the Performance of Polypropylene-Based Fibrous Filters with Polyvinylimidazole Grafted Surfaces for Separation of Nonsteroidal Drugs in an Aqueous Medium

Abstract To address global NSAID water pollution, an imidazolium ion-rich adsorption membrane (PPF–PVI) was fabricated via simple one-step UV grafting of vinylimidazole on meltblown fabric. Benefiting from the open porous substrate, the resultant PPF–PVI exhibited a water flux up...

Prediction of Corrosion and Related Damage States in High-Temperature Equipment Using Mechanism and Data Fusion

High-temperature equipment in the petrochemical industry can develop multiple forms of damage during long-term service, with corrosion often accounting for a relatively high proportion. The presence of other damage forms complicates corrosion identification and equipment conditio...

Sex Differences in Aggressive Traits and Superior Temporal Cortical Responses to Monetary Loss

Background: Individuals vary in aggression traits. Here, we investigated how individual aggression is associated with altered reward and punishment processing in the brain and the neural bases of sex differences. Methods: Aggression was assessed by the Achenbach Adult Self-Report...

Nanozyme‐Assisted Engineered Oncolytic Adenovirus for Improving Intratumoral Immune Deficiency and Enhancing Cancer Immunotherapy
