Canine brachycephalic obstructive airway syndrome as a model for studying the effects of obstructive sleep apnea during pregnancy

Animal Models and Experimental Medicine, EarlyView.
We observed a negative effect of brachycephalic obstructive airway syndrome (BOAS) in a staggered manner based on the severity of the condition on respiratory and cardiac patterns, glycemia, acid–base balance, fetal growth, and uterine artery hemodynamics, thus requiring adaptations within the fetal–placental unit. Severely affected bitches had uterine

Wärmeträgerflüssigkeiten als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für schnellladefähige Lithium‐Metall‐Batterien mit erhöhter Sicherheit

Angewandte Chemie, EarlyView.
Zwei fluorierte Ether aus dem Bereich der Wärmeträgerflüssigkeiten werden als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für lithiummetallbasierte Batterien eingesetzt. Die ternäre Diluentenmischung erhöht die Ionenmobilität, senkt die Überspannung und verbessert so coulombische Effizienz und Lebensdauer der Zelle bei hohen Stromdichten, was

Heat Transfer Fluids as Co‐Diluents in Localized High‐Concentration Electrolytes for High‐Rate Lithium Metal Batteries With Enhanced Safety

Angewandte Chemie International Edition, EarlyView.
Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...

Validación de un método cromatográco y determinación de sulfatos en productos de corrosión atmosférica del zinc expuesto en ambientes de SO2 y NO2

Revista Facultad de Ingeniería Universidad de Antioquia, 2005
Se estudió el efecto del SO2 y el NO2 en la corrosión atmosférica del zinc, determinando la presencia de sulfatos como productos principales de la corrosión atmosférica de dicho metal cuando se expone a este tipo de ambientes.
