Measuring Heat Capacities Of Pressurized ZIFs
A new method for measuring the low temperature heat capacities of materials under pressure has been developed. The technique can be utilized to measure the low temperature of heat capacity of metal organic frameworks and similar materials while they are loaded with gas molecules. Samples are prepared and sealed into aluminum pans under pressures up to 100 psi, and then measurements are carried out on a QD PPMS. Initial measurements of benzoic acid have shown the accuracy of the technique, and measurements on zinc 2-methlyimidazolate loaded with carbon dioxide show that the gas remains sealed in the pan over the course of a measurement.
