Bulk Density(ρ B): Bulk density of a powder is the weight of loose powder sample in unit volume. ρ B =M/V In this video, Bettersize application engineer Shelly Zhang is measuring the bulk density of ...

Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

AbstractThe calculation of the molecular column density from molecular spectral (rotational or ro-vibrational) transition measurements is one of the most basic quantities derived from molecular ...

Speeds time-to-market with flexible software options, simplified system integration and synchronization, and application-specific measurement capabilities Scalable, compact solution that gives digital ...

Yes, the future of the world’s climate is tied to the ability of forests to absorb atmospheric carbon. But exactly how well they can do that job depends on the density of the forests themselves, and ...
