Freezing point depression lab Using Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-buta...
Water interacting with a polymer reveals a number of properties very different to bulk water. These interactions lead to the redistribution of hydrogen bon
6a). The anti-freezing property of the microfiber with the freezing point of −41.1 °C benefits the maintenance of its soft solvent-swollen PVA networks at subzero temperatures for strain sensing. Moreover, although the DC power may lead to the accumulation of ions at the interface between...
Traditional conductive hydrogels are prone to freezing when the internal water reaches the freezing point, leading to flexibility and functionality loss. To increase the operational temperature range for the utilization of conductive hydrogels, as demonstrated in Table 1, researchers have found that supple...
