Using NASA's Submillimeter Wave Astronomy Satellite (SWAS), we have examined the production of water in quiescent and shocked molecular gas through a survey of the 556.936 GHz 110-101 transition of or...
Although liquid water covers a majority of Earth's surface, scientists are still searching for planets outside our solar system that contain water. California Institute of Technology researchers have ...
Microcalorimetric investigation of water vapor adsorption on silica gel
Microcalorimetry Diffusivity Silica gel–water pair Heat of adsorption
2011/11/10
Water vapor adsorption on silica gel was investigated using Tian–Calvet-type microcalorimetry. Differential heat of adsorption data was obtained. The setup of microcalorimetry was used volumetric syst...
