A scalable approach using a gCN-covalent organic framework hybrid catalyst towards sustainable hydrogen production from seawater and wastewater.

The photocatalytic generation of H using covalent organic frameworks (COFs) is gaining more interest. While numerous reports have focused on the production of H from deionized water using COFs, the inability to produce H from industrial wastewater or seawater is a common limitation in many reported catalysts. Additionally, many of these reports lack a clear path to scale up the catalyst synthesis.

Errors in Aerosol Inhaler Use and Their Effects on Maternal and Fetal Outcomes among Pregnant Asthmatic Women (Subanalysis from QAKCOP Study).

Data on inhaler technique and its effects on maternal and fetal outcomes during pregnancy are seldom reported. The primary objective of this study was to evaluate inhaler technique and identify errors in inhaler use among pregnant women with asthma. Secondary objectives were to identify factors associated with poor inhaler technique and study the association between inhaler technique and maternal and fetal outcomes.
