Deliquescent materials are sufficiently hygroscopic that they dissolve in the water they absorb, forming an aqueous solution. Hygroscopy is essential for many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal .
The selection of hygroscopic salts have to provide the following strict criteria in order to be of interest of use in the hygroscopic cycle: Highly hygroscopic compounds, deliquescent materials; Less volatile than water (vapor pressure lower than water), with easily reversible desorption into water and steam in the boiler
Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not ...
Secondly, Dessication has very little to do with Deliquescence, in spite of how many deliquescent materials are use for dessication. Dessication is a process for removing water; Deliquescence is a property of certain molecules. Merging would just provide confusion to viewers of the encyclopedia.

In the near-infrared range liquid water has absorption bands around 1950 nm (5128 cm −1), 1450 nm (6896 cm −1), 1200 nm (8333 cm −1) and 970 nm, (10300 cm −1). [ 19 ] [ 20 ] [ 15 ] The regions between these bands can be used in near-infrared spectroscopy to measure the spectra of aqueous solutions, with the advantage that glass is ...
Semiheavy water is the result of replacing one of the protium in normal water with deuterium. [1] It exists whenever there is water with light hydrogen (protium, 1 H) and deuterium (D or 2 H) in the mix. This is because hydrogen atoms (1 H and 2 H) are rapidly exchanged between water molecules. Water containing 50% 1 H and 50% 2 H, is about 50% ...

Sea salt particle number concentration can reach 50 cm −3 or more with high winds (>10 m s −1), compared to ~10 cm −3 or less under moderate wind regimes. [3] Due to the dependence on wind speed, it could be expected that sea-salt particle production and its impacts on climate may vary with climate change.
