In chemical thermodynamics, isothermal titration calorimetry (ITC) is a physical technique used to determine the thermodynamic parameters of interactions in solution. [ 1 ] [ 2 ] It is most often used to study the binding of small molecules (such as medicinal compounds) to larger macromolecules ( proteins , DNA etc.) in a label-free environment.
A calorimeter is a device used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists ...
Van 't Hoff plot for an exothermic reaction. For an exothermic reaction, heat is released, making the net enthalpy change negative. Thus, according to the definition of the slope: =, For an exothermic reaction Δ r H < 0, so
The measurement of heat changes is performed using calorimetry, usually an enclosed chamber within which the change to be examined occurs. The temperature of the chamber is monitored either using a thermometer or thermocouple , and the temperature plotted against time to give a graph from which fundamental quantities can be calculated.
Constant flux calorimetry is an advanced temperature control mechanism used to generate accurate calorimetry. It operates by controlling the jacket area of a laboratory reactor while maintaining a constant inlet temperature of the thermal fluid. This method allows for precise temperature control, even during strongly exothermic or endothermic ...
A couple in Australia have been accused of faking their young son's cancer diagnosis "It will be alleged that the accused shaved their 6-year-old child’s head, eyebrows, placed him in a ...

Heat losses or gains from outside the system via the vessel walls and cover; Differences in the temperature between the titrant and the titrand; Evaporative losses from the surface of the rapidly mixed fluid;
Cooking oils include a wide range of products, from canola oil to olive oil, coconut oil and more. The nutritional pros and cons of cooking oils are a frequent subject of debate online, especially ...
