Soldering flux is (or at least, should be) one of the ubiquitous features of any electronics bench. It serves the purpose of excluding oxygen from a solder joint as it solidifies, and in most ...

How do you clean the residual flux off your boards? There are plenty of ways to go about the job, ranging from “why bother?” to the careful application of isopropyl alcohol to every joint with ...

Despite accounting for approximately half of habitable land use, the atmospheric chemistry of agricultural regions is understudied ... For instance, the formation of aerosol particles (“hazes”) may ...

Marine chemistry; air-sea CO2 flux; carbon cycling in estuaries and coastal oceans; global changes; sensor development; acid-base and redox chemistry in aquatic environments.

Oak Ridge National Laboratory discovered a rare radioactive element called promethium. Nearly 80 years later, scientists have unlocked it.
