Structural damage for spacecraft is mainly due to impacts such as collision of meteorites or space debris. We present a structural health monitoring (SHM) system for space applications, named Adverse Event Detection (AED), which integrates an acousti

Two non-equilibrium conditions have been identified in aqueous biphasic systems: the partitioning of subcellular biological particles between two polymer-containing phases, and the demixing of solutions of a salt and a polymer. In partitioning experi

Several experiments proposed for flight on the Space Shuttle require the use of gas lasers, but few data are available on the behavior of gas lasers in a low-gravity environment. The response time of the laser plasma to the absence of gravity was cal
