“…When crystallizing from melting state, PHB may form large spherulites, which give rise to its brittle properties [8][9][10]. Meanwhile, high crystallinity also influences other properties of PHB including degradability and hydrophilicity.…”

“…Furthermore, temperature-modulated DSC (TMDSC) results (Fig. 3a-d) showed the samples to undergo transitions that are typical of semicrystalline materials [14][15][16][17]. From the TMDSC results, the samples undergo a step-change in baseline of the heat flow signal (R-1 in Fig.…”

Dehydrated DLPC, DMPC, DPPC and DSPC have been characterised at temperatures below the diacyl carbon chain-melting transition (T m ), using DSC. For the first time, the existence of pre-Tm transition processes, which are, usually, only observed in the colloidal/liposomal state of saturated phospholipids, has been detected for the dehydrated phosphatidylcholines. Temperature-modulated differential scanning calorimetry was used to characterise the several complexes, overlapping pre-T m transition processes. Kinetic studies of the chain-melting (T m ) transition show the activation energy dependence on a (conversion rate), i.e. activation energy decreases as the transition progresses, pointing to the importance of initial cooperative (intra-and inter-molecular) mobility. Furthermore, the activation energy increases with increase in diacyl chain length of the phosphatidylcholines which supports the finding that greater molecular interactions of the polymer chain and its head groups in the dehydrated solid state lead to enhanced stability of dehydrated phosphatidylcholines.
