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 ...
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 •6 H 2 O contains the neutral molecule trans-CoCl 2 (H 2 O) 4 and two molecules of water of crystallization. [8] This species dissolves readily in water and alcohol. The anhydrous salt is hygroscopic and the hexahydrate is deliquescent. [citation needed] The dihydrate, CoCl 2 (H 2 O) 2, is a coordination polymer.
The critical relative humidity (CRH) of a salt is defined as the relative humidity of the surrounding atmosphere (at a certain temperature) at which the material begins to absorb moisture from the atmosphere and below which it will not absorb atmospheric moisture.
Xerochasy is dehiscence that occurs upon drying, and hygrochasy is dehiscence that occurs upon wetting, the fruit being hygroscopic. Dehiscent fruits that are derived from one carpel are follicles or legumes, and those derived from multiple carpels are capsules or siliques. [3] One example of a dehiscent fruit is the silique.
Nickel(II) chloride (or just nickel chloride) is the chemical compound NiCl 2.The anhydrous salt is yellow, but the more familiar hydrate NiCl 2 ·6H 2 O is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis.
Vineyards can be found on mountainsides and valley floors, in areas that receive plenty of rain or are extremely arid, alongside coasts, or tucked inland.
The air-cooler used in the hygroscopic cycle cools a liquid flow with concentrated hygroscopic compound, with an overall volumetric heat capacity much higher than the steam traditionally condensed in the air cooled condenser mentioned earlier, thus reducing the power needed for ventilation, [8] and needing less surface area for heat exchange ...
