Inhibition mechanisms of steel slag on the early-age hydration of cement

, 2021
Steel slag inhibits the early-age hydration of cement. However, its mechanism is still unclear. In this paper, the early-age hydration kinetics and the evolution of the solid phases, aqueous species and microstructures in a cement-steel slag composite ...

Strong Surface Hydration and Salt Resistant Mechanism of a New Nonfouling Zwitterionic Polymer Based on Protein Stabilizer TMAO.

Journal of the American Chemical Society, 2021
Zwitterionic polymers exhibit excellent nonfouling performance due to their strong surface hydrations. However, salt molecules may severely reduce the surface hydrations of typical zwitterionic polymers, making the application of these polymers in real ...

Topology‐Controlled Hydration of Polymer Network in Hydrogels for Solar‐Driven Wastewater Treatment

Advances in Materials, 2020
Solar‐driven interfacial evaporation provides a promising method for sustainable freshwater production. However, high energy consumption of vapor generation fundamentally restricts practicality of solar‐driven wastewater treatment. Here a facile strategy

Hydration Management

Journal of Gerontological Nursing, 2020
Optimal hydration is essential to health, yet many common health problems of older adults are exacerbated by suboptimal hydration, including falls, adverse medication events, and urinary tract infections to name a few. Understanding dehydration in older adults is difficult, and causes for inadequate intake are multifocal.

Advances in understanding cement hydration mechanisms

Cement and Concrete Research, 2019
Progress in understanding hydration mechanisms of alite and Portland cement is reviewed. Up to the end of the induction period, dissolution rates determined by the undersaturation of the solution dominate the reaction, but, better understanding is needed

Hydrophobic Hydration and the Formation of a Clathrate Hydrate

Physical Review Letters, 1998
We report a direct comparison of the local structure of the hydrophobic hydration of krypton in both the liquid and solid states by the extended x-ray absorption fine structure spectroscopy technique. The evolution of an ordered hydration shell of the nonpolar gas moiety is followed as the liquid to solid phase transition progresses. The formation of a
