A structure of polyurethane foam (PUF) is formed via chemical reactions between diisocyanate and polyol, namely it is a reaction between isocyanate and hydroxyl groups.
It is known [12] that a value of abrupt change in heat capacity depends on the polymer chemistry; however, for the smallest particle capable of moving autonomously, the heat capacity increment during glass transition is practically constant.

The structural features and electronic structures of PtCl2 NCs/graphene as a function of PtCl2 amount were measured by Raman spectroscopy.
