Heat Capacity. The specific heat capacity was measured using the Modulated DSC (MDSC) mode on the TA Q100 DSC . The correction factor was initially found using a sapphire disc calibrant at the midpoint temperature (50 C). Following that the samples, (weighing approx. 15 mg) underwent a modulated ramp at 3 K min -1 , with an amplitude of 1 K and period of 120s, as recommended for crimped hermetic aluminium pans, between 0 -100 C. Three non-concurrent measurements were carried out for each sample. The use of modulation enables the reversible and non-reversible components of heat capacity to be discerned. A typical heat capacity, temperature plot is shown in Figure . The thermal diffusivity (𝑘), density (𝜌), and reversible heat capacity values (𝑐 𝑝 ) were used to calculate the in plane thermal conductivity (𝛼) using 𝑘 = 𝛼𝜌𝑐 𝑝 .
