Non- Ideality and Ion-Pairing in Saturated Aqueous Solution of Lithium Carbonate at 25°C

Using Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubility of Li2CO3 in waterat 25°C was determined. Comparing the value of thermodynamic solubility product constant, Ksp(th),(Ksp(tn) = exp(—AG.ss/RT)) of the mentioned salt to the value which is obtained from the observed solubility,shnolL-1 , and activity coefficients, f+ and f, which are estimated upon the extend...

Thermodynamics of Non-Ideality and Ion-Association in Saturated Aqueous Solution of Barium Nitrate at 25° C

Using Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubility of Ba (NO3 )2 inwater at 25.0 ° C was determined. Activity coefficients, f+ and f_ of Bat) and N0i(aq) ions in the saturatedsolution at 25.0 ° C were estimated upon the extended Debye —Hiickel theory and then, the constantK'sp =[Ba2+1f+ [NO-3 ]2 f 2 was evaluated. Comparing the value of thermodynamic solubi...

Transfer free graphene growth on SiO2 substrate at 250 °C

Low-temperature growth, as well as the transfer free growth on substrates, is the major concern of graphene research for its practical applications. Here we propose a simple method to achieve the transfer free graphene growth on SiO2 covered Si (SiO2/Si) substrate at 250 °C based on a solid-liquid-solid reaction. The key to this approach is the catalyst metal, which is not popular for graphene ...
