“…Recent reviews have critically evaluated solubility in the lithium nitrate–water binary system, as well as in other ternary and multicomponent systems containing lithium nitrate, and have extracted the empirical parameters necessary to predict isotherms in these systems . The enthalpy of fusion of lithium nitrate trihydrate has been measured by a number of authors using calorimetric techniques; these values are summarized in Table . − Reported enthalpies of fusion are within 5 % of each other. As pointed out by Guion et al (1983), many of the enthalpy of fusion and melting temperature data that exist in the literature are propagated in simple tabular form, and the original experimental details and reference are uncertain .…”

“…Again, the thermal conductivity for lithium nitrate–water solutions has been measured by the transient hot wire technique at (313, 333, and 363) K, but only up to concentrations of ≈14 mol·kg –1 . The thermal diffusivity was also measured for LiNO 3 ·3H 2 O using a custom transient measurement apparatus, but the uncertainty of this approach was not quantified and is likely large, and the phase of LiNO 3 ·3H 2 O during the measurement was not specified . Finally, thermal conductivity of the solution can be calculated using a simple linear model and empirically determined parameters correlating the effect of various cation and anion species on thermal conductivity .…”

Wettability and its influence on graphene nansoheets as electrode material for capacitive deionization

“…Surprisingly, Koratkar and his group found that the contact angle of graphene films could be tailored from superhydrophobic to superhydropholic by controlling the roughness and surface chemistry of GNS [18]. Most likely, the film composed with hydrophilic graphene will show much better wettability and water spreading [19]. The aim of our current research is to optimize the wetting behavior of GNS-based electrodes to seek the possibility of improving their CDI performance.…”
