“Branched polyethyleneimine (PEI), consisting of numerous imine groups, is employed for CO 2 gas detection, attributed to the interaction between imine groups and CO 2. Incorporating functionalized ...

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon ...

This work, we have demonstrated a low-cost and effective chemiresistive CO 2 sensor based on a composite of functionalized carbon nanotubes (f-CNTs) with polyethyleneimine (PEI). The resulting sensor ...

Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers advanced the technology available to measure carbon dioxide in the ocean. Scientists ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...
