Solutions calorimetry apparatus for undergraduate teaching

Journal of Chemical Education, 1991
Because many students do not understand the function of the bridge, these authors designed an activity that provides access to each of its components.

Solution Calorimetry Under Hydrothermal Conditions

Reviews in Mineralogy and Geochemistry, 2013
The first quantitative studies of the thermodynamics of hydrothermal solutions were made in 1903 by A.A. Noyes and W.D. Coolidge (1903), who used the change in conductance associated with ionization to measure the ionization constants of water and aqueous acids and bases up to about 300 °C at steam saturation.

Solution calorimetry as an alternative approach for dissolution testing of nanosuspensions

European Journal of Pharmaceutics and Biopharmaceutics, 2010
The formulation of poorly soluble drugs as nanocrystals/nanosuspensions has rapidly evolved during the past decade into a mature drug-delivery strategy. The major characteristic of these systems is the high drug dissolution rate, enabling bioavailability enhancement after oral administration.

Enthalpies of Vaporization and Sublimation of the Halogen-Substituted Aromatic Hydrocarbons at 298.15 K: Application of Solution Calorimetry Approach [PDF]

Journal of Chemical & Engineering Data, 2015
© 2015 American Chemical Society. Recently, the solution calorimetry has been shown to be a valuable tool for the indirect determination of vaporization or sublimation enthalpies of low volatile organic compounds.

Recent developments in micro solution calorimetry

Thermochimica Acta, 1985
Abstract A group of microcalorimetric vessels primarily designed for the dissolution of slightly soluble compounds in water is described. Gaseous and liquid solutes are-injected into a flow of solvent and the measurements in these cases are automatized by means of microprocessors. The amount of solute used in each experiment is typically 0.4 ml and 0.

Calorimetry—an important tool in solution chemistry

Thermochimica Acta, 2004
Abstract Calorimetry belongs to the most important experimental techniques. It is the only experimental method allowing for direct measurements of various physical and chemical processes and reactions. When appropriate model is used, analysis of results on molecular level is possible.
