Sealing Failure Behavior of Metal‐Sealed Bolted Flange Connections Under Cyclic Loading

ABSTRACT Metal‐sealed bolted flange connections are critical in well‐control surface facilities, where cyclic loads may induce bolt loosening, leakage, and sealing failure. This study investigated the failure behavior of 6BX metal‐sealed flange connections under cyclic loading us...

Patient Shielding in Computed Tomography: Analysis of Influencing Factors and a Conceptual Framework for Decision-Making

Background: Although lead shielding during computed tomography (CT) examinations has served as routine clinical practice, its actual efficacy and execution remain controversial, showing noticeable divergences across national policies and international clinical guidelines. This di...

Computational Guided Structural Design for Optimized Pore Size and Shape Metal‐Organic Framework Enabling One‐Step CH 4 and C 3 H 8 Purification From CH 4 /C 2 H 6 /C 3 H 8 Ternary Gas Mixture

ABSTRACT Current natural gas upgrading strategies primarily focus on CH 4 recovery, treating C 2 H 6 and C 3 H 8 merely as impurities, which results in resource wastage. In this work, an advanced industrial operation, simultaneous separation of both pure CH 4 and C 3 H 8 from CH...

Probiotic-hydrogel systems for microbiome-associated diseases: design principles, preclinical evidence, and translational challenges

The human microbiome provides a robust ecosystem for mucosal barrier function, immune regulation, metabolism, and resistance to pathogen infection. Dysbiosis causes inflammatory bowel disease, oral inflammation, wound damage, skin disease, and cancer-related immune dysregulation....
