By implementing rapid sorption-desorption kinetics and operating 14–24 cycles per day, this technique produced an equivalent water yield of 5.8–13.3 L kg −1 of sustainable raw materials, demonstrating the potential for low-cost, scalable atmospheric water harvesting. [36] Hygroscopic glues are candidates for commercial development.
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.

A humectant / h juː ˈ m ɛ k t ən t / is a hygroscopic (water-absorbing) substance used to keep things moist. They are used in many products, including food, cosmetics, medicines and pesticides. When used as a food additive, a humectant has the effect of keeping moisture in the food. [1]
