Super hygroscopic polymer films composed of biomass and hygroscopic salts are able to condense moisture from atmospheric humidity. [16] 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 ...
Under more "comfortable" conditions, it does not so it isn't considered deliquescent. So it is like relative hardness in minerals. One might consider two hygroscopic salts in a sealed chamber; the more hygroscopic one would dessicate the other. A comprehensive article would rank "deliquescent" substances by their critical humidity.--
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 ...
[2] [3] This is the opposite use of a hygroscopic material where it is used as a desiccant used to draw moisture away. In pharmaceuticals and cosmetics, humectants can be used in topical dosage forms to increase the solubility of a chemical compound's active ingredients , increasing the active ingredients' ability to penetrate skin, or its ...
The blue silica gel in the space below the platform is used as the desiccant. Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.
Cabot Sweetened Light Whipped Cream One editor compared the flavor of this whipped cream to sweetened condensed milk. Texture-wise, it was a bit surprising for one editor, who said it felt "fluffy ...
Elaborate and expensive Christmas light displays have become a hallmark of the holiday season, with enthusiasts all over the world pouring in time, effort, and tons of money to create these ...
A simplified Jablonski diagram illustrating the change of energy levels.. The principle behind fluorescence is that the fluorescent moiety contains electrons which can absorb a photon and briefly enter an excited state before either dispersing the energy non-radiatively or emitting it as a photon, but with a lower energy, i.e., at a longer wavelength (wavelength and energy are inversely ...
