TL;DR: In this paper, the properties of the graphite matrix and paraffin phase change material (PCM) composites were measured for graphite matrices with bulk densities ranging from 50g/L to 350 g/L.

TL;DR: In this article, the authors examined the crystallization behavior after partial or complete melting of the α phase of iPP by combined differential scanning calorimetry (DSC) and optical microscopy: the results are directly correlated with corresponding morphologies of microtome sections of DSC samples.
Abstract: The crystallization behavior after partial or complete melting of the α phase of iPP is examined by combined differential scanning calorimetry (DSC) and optical microscopy: calorimetric results are directly correlated with corresponding morphologies of microtome sections of DSC samples. On partial melting at various temperatures (hereafter referred to as Ts) located in a narrow range (4°C) below and near Tm, the number of nuclei increases (as in classical self-nucleation experiments), by several orders of magnitude; on subsequent cooling, the crystallization peak is shifted by up to 25°C. After partial melting in the lower part of the Ts range and recrystallization, the polymers display a prominent morphology “memory effect” whereby a phantom pattern of the initial spherulite morphology is maintained.
After partial melting in the upper part of the Ts range the initial morphology is erased and self-nucleation affects only the total number of nuclei. The present experimental procedures make it possible to define, under “standard” conditions, the crystallization range of the polymer and in particular, the maximum crystallization temperature achievable when “ideally” nucleated. © John Wiley & Sons, Inc.

TL;DR: In this article, a kind of spherical cellulose nanocrystals was prepared by hydrolysis of microcrystalline cellulose with mixed acid and two methods were used: diminishing the acid sulfate groups by desulfation and neutralizing them by using NaOH solution.
