We report a wide-field compressive diffuse optical tomography (DOT) system – optical mammography co-imager (OMCI) – which aims to augment tens of thousands of existing x-ray mammography or ...

Researchers at the University of Illinois Urbana-Champaign developed an instrument to measure the density of the dust that kicks up when spacecraft thrusters interact with planetary surfaces as it ...

Temperature, viscosity, air pressure as well as sampling and cleaning, are the key factors influencing measurement accuracy. Density is largely temperature-dependent. The density of a sample is ...

Powder is a collection of single solid particles, which in most cases may be considered a basic unit. Powder is typically comprised of solid particles, interparticle voids, as well as open and closed ...
