The drying of soil: Thermal regimes and ambient pressures [PDF]
Agricultural Meteorology, 1967 SUMMARY Evaporation from a loam soil was studied in the laboratory during the fallingrate stage of drying. The primary variables were temperatures regimes and ambient pressures. The data suggested that: (a) there is a significant relation between the soil temperature and the vapor pressure of water in the air above the surface; (b) the water vapor ...

Synthesis of sodium silicate-based silica aerogels with graphene oxide by ambient pressure drying [PDF]
Journal of Porous Materials, 2021 AbstractHere we study how graphene oxide affects silica aerogels and their physical and mechanical properties by examining volume shrinkage, pore volume, surface area and compressive strength of these composite aerogels. Composite aerogels were made through adding different amount of graphene oxide (GO) to sodium silicate precursor by using ambient ...
