Microcalorimetry on Metastable Beta Phase Alloys Subjected to Applied Stress
The development of a High Sensitivity Scanning Stress Microcalorimeter for the study of martensitic phase transformations in beta phase CuAlNi single crystal tensile specimens is described. The design of this system is discussed with reference to an earlier version. The values of calorimetric sensitivity reported for the new system represent a significant improvement over the prototype and a co...
متن کاملStandards in Isothermal Microcalorimetry
The main calorimetric principles used in isothermal microcalorimetry are briefly discussed. Different chemical calibration and test reactions are discussed, with a focus on reactions suitable for ambient conditions: reactions initiated by mixing of liquids (including titration microcalorimetry), dissolution of solid compounds and of slightly soluble gases, a photochemical process, and thermal p...
متن کاملMicrocalorimetry of biological macromolecules.
The capabilities of contemporary differential scanning and isothermal titration microcalorimetry for studying the thermodynamics of protein unfolding/refolding and their association with partners, particularly target DNA duplexes, are considered. It is shown that the predenaturational changes of proteins must not be ignored in studying the thermodynamics of formation of their native structure a...
متن کاملRadical thermochemistry and organic reactions*
Most free radicals are transient species and it is therefore difficult to measure their thermochemical properties. We have used two new techniques that address this problem. Photoacoustic calorimetry was used to measureheats of formation of free radicals and thus homolytic bond strengths, while photomodulated voltammetry was used to measure their oxidation and reduction potentials. The data off...
متن کاملDifferential scanning microcalorimetry
Differential scanning calorimetry (DSC) is an experimental technique to measure the heat energy uptake that takes place in a sample during controlled increase (or decrease) in temperature. At the simplest level it may be used to determine thermal transition (“melting”) temperatures for samples in solution, solid, or mixed phases (e.g. suspensions). But with more sensitive apparatus and more car...
