Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Usefulness of INTELLiVENT-ASV for postoperative ventilator-associated pneumonia: a case report

JA Clinical Reports, 2019
Background INTELLiVENT®-ASV (iASV) is a respiration mode on the Hamilton G5. The ventilator uses a closed-loop mechanism that automatically adjusts settings related to oxygenation and ventilation.

Beyond the apnea–hypopnea index in COPD–OSA overlap syndrome: a mechanism-informed framework for nocturnal oxygenation and ventilation

Frontiers in Physiology
BackgroundIn chronic obstructive pulmonary disease (COPD)–obstructive sleep apnea (OSA) overlap syndrome, the apnea–hypopnea index (AHI) confirms and grades OSA but does not fully explain nocturnal hypoxemia or carbon dioxide retention.ObjectiveWe ...

Design of a crab-like bistable mechanism for nearly equal switching forces in forward and backward directions

, 2018
A compliant bistable mechanism with a crab-like structure for nearly equal switching forces in the forward and backward directions is developed. It consists of four crab-leg-like beams and a shuttle mass.

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

Anesthetic Oxygen Use and Sex Are Critical Factors in the FLASH Sparing Effect

Advances in Radiation Oncology
Purpose: Ultra High Dose-Rate (UHDR) radiation has been reported to spare normal tissue, compared with Conventional Dose-Rate (CDR) radiation. However, important work remains to be done to improve the reproducibility of the FLASH effect.
