Hygroscopic biological matter in plants, fungi and bacteria make up a large fraction of Earth's biomass1. Although metabolically inert, these water-responsive materials exchange water with the environment and actuate movement2-5 and have inspired technological uses6,7. Despite the variety in chemical composition, hygroscopic biological materials across

Experimental investigation into gas production from methane hydrate in sediment by depressurization in a novel pilot-scale hydrate simulator [PDF]
Applied Energy, 2012 The gas production behavior from methane hydrate in the sediment by depressurization was investigated in a novel pilot-scale hydrate simulator (PHS), a three-dimensional pressure vessel of 117.8 L Experimental results are compared with those in a cubic

Water supply is a basic public problem. In modern science, three periods with different approaches to define recommended water intake in adults can be distinguished. Pediatricians agree that hydration in children may be optimal only in breastfed infants.

The hydration of phospholipids
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1974Abstract The adsorption isotherms of egg phosphatidylcholine, egg phosphatidylethanolamine and bovine phosphatidylserine, in both their lyso and diacyl forms, have been determined in an examination of the hydration characteristics of films of these phospholipids.

AbstractThe hydration of several polyacids has been investigated with special attention to the effects of neighboring charged groups and hydrophobic groups on the hydration regions. The molar volume change due to the structural change of water by the hydration was obtained by the method of refractivity measurement.

The eight hydrates of strychnine hydrate
2020Commercial samples of strychnine sulfate were used as the starting material in crystallization experiments accompanied by stability studies. Eight hydrate forms (HyA-HyG), including five novel hydrates, were verified. The crystal structures of HyA (pentahydrate) and HyF (hexahydrate) were determined from single-crystal X-ray diffraction data.

Science, 1969
Frozen protein and nucleic acid solutions at -35°C show relatively narrow (100 milligauss) proton nuclear magnetic resonance signals which are assignable to water that is sufficiently mobile to reduce the dipolar broadening normally associated with solids. Hydration was found to be 0.3 to 0.5 gram of water per gram of protein.
