Thermochromatography of Heavy Actinides - Determination of the Sublimation Enthalpy of Es [PDF]
, 1997 The adsorption of Cf, Es, and Fm on several metals was studied thermochromatographically. In all systems investigated Es is adsorbed between the Cf and Fm, due to the increasing metallic divalency in the second half of the actinide series.

Calculation of Crystal-Solution Dissociation Constants
Biomolecules, 2022 The calculation of dissociation constants is an important problem in molecular biophysics. For such a calculation, it is important to correctly calculate both terms of the binding free energy; that is, the enthalpy and entropy of binding.

Thermodynamic properties of L-menthol in crystalline and gaseous states
Тонкие химические технологии, 2020 Objectives. Menthol causes a cooling sensation and reduces the nerve activity when it is applied locally, ingested, or inhaled. This feature explains its extensive use as both an aromatizer and a flavoring agent in food manufacturing, tobacco industry ...

On the Enthalpy of Formation and Enthalpy of Sublimation of Dihydroxylammonium 5,5′‐bitetrazole‐1,1′‐dioxide (TKX‐50) [PDF]
, 2023 The thermodynamic characterization of dihydroxylammonium 5,5′-bitetrazole-1,1′-dioxide (TKX-50) was reinvestigated. Although TKX-50 is one of the most promising new-generation energetic materials, contradictory reports are found in the literature with ...

Structure and stability of aquotetrafluorouranyl(VI) in the solid state - Density functional study of [UO2F4(H2O)][NMe4]2·2H2O1,2 [PDF]
, 2009 Periodic density functional computations have been performed for solid [UO2F4(H2O)][NMe4]2·2H(2)O at the BLYP level. A model with disordered fluoro and aquo ligands in the uranyl anion is significantly lower in energy than one with a symmetrical ...
