The design and operation of a tabletop electrostatic force balance suitable for measurement of milligram masses of fluid samples is described. The design incorporates a 4-bar linkage mechanism and ...

The ocean serves as Earth's largest dynamic carbon sink, absorbing 400 million tons of carbon dioxide (CO₂) annually through continuous exchange with the atmosphere. Researchers at Yale have now ...

In the standard formulation of the population balance equation that consists of breakage terms, significant loss of mass is observed for the dispersed phase. This mass loss is actually caused by the ...

With the help of powerful computers, researchers discovered a four-sided shape that naturally rests on one side, and built a ...

Atmospheric pressure chemical ionization (APCI) offers the advantage of molecular ion information with low fragmentation. Hyphenating APCI to gas chromatography (GC) and ultrahigh resolution mass ...

Scientists have developed a material with photosynthetic bacteria that convert carbon dioxide into a mineral skeleton. The material hardens over time, so it could be used for buildings, they say.
