Adiabatic Reaction Calorimetry

Kinetics of solid-gas reactions characterized by scanning AC nano- calorimetry with application to Zr oxidation

Scanning AC nano-calorimetry is a recently developed experimental technique capable of measuring the heat capacity of thin-film samples of a material over a wide range of temperatures and heating rates. Here we describe how this technique can be used to study solid-gas phase reactions by measuring the change in heat capacity of a sample during reaction. We apply this approach to evaluate the ox...

Solid State Polymorphism and Dynamics of 2,2-Dimethylbutan-1-ol as Studied by Adiabatic Calorimetry and Dielectric Spectroscopy

2,2-dimethylbutan-1-ol, known as neohexanol, was studied by adiabatic calorimetry and dielectric spectroscopy. Details of complex solid state polymorphism and relaxational dynamics were identi ed and described. System of phases of neohexanol was found to be monotropic with three orientationally disordered crystalline phases besides isotropic liquid and ordered crystal. Moreover, two subsequent ...

Calorimetry of technical microbial reactions

Heat generation is a very conspicuous phenomenon in large scale bioreactors and could in principle quite easily be measured by the temperature increase of the cooling water. Taking yeast cultures growing on a mixed oxido-reductive metabolism for various reasons as an example, this paper demonstrates how heat dissipation measurements may be used in combination with one other on-line measurement ...
