Thermodynamic study on the interaction of β-CD with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298K. when β-CD is added to the interpolymer complex, competition is created between host-guest and Hydrogen bond. Enthalpy of interaction between the β-CD and interpolymer complex was calculated using the extended solvation theory. P=1 Shows that w...

Accurate label-free methods or assays to obtain the initial reaction rates have significant importance in fundamental studies of enzymes and in application-oriented high throughput screening of enzyme activity. Here we introduce a label-free approach for obtaining initial rates of enzyme activity from heat measurements, which we name initial rate calorimetry (IrCal). This approach is based on o...

Adsorption microcalorimetry measures the energetics of adsorbate-surface interactions and can be performed by use of several different techniques. This review focuses on three methods: single-crystal adsorption calorimetry (SCAC), isothermal titration calorimetry (ITC), and electrochemical adsorption calorimetry. SCAC is a uniquely powerful technique that has been applied to a variety of atoms ...
