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

Annual Review of Physical Chemistry, 2017
Existence of a hydrated electron as a byproduct of water radiolysis was established more than 50 years ago, yet this species continues to attract significant attention due to its role in radiation chemistry, including DNA damage, and because questions persist regarding its detailed structure.

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.

Biopolymers, 1968
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.

An experimental study on the early-age hydration kinetics of cemented paste backfill
Construction and Building Materials, 2019Understanding the early-age hydration kinetics of cemented paste backfill (CPB) is necessary for its successful application. In this paper, the early-age hydration heat evolution of CPB was experimentally studied using an isothermal calorimeter ...

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.

The role of admixed graphene oxide in a cement hydration system
Carbon, 2019Graphene oxide (GO), which has been sucessfully used in cement composites as an admixture, can improve their mechanical and durability properties. This study examined and elucidated the effect of GO on the hydration products of a cement system in detail.
