The effect of lignin nanoparticles (LNPs) on the crystallization kinetics poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter 85 nm (with relatively large polydispersity) by an ultrasonication method. PEO-based nanocomposites four different LNP contents (5, 10, 15, 20 wt %) were prepared subject isothermal nonis...

In this paper, the crystallization, fusion, and activation energy (Ea) of PBT/TiO2 were thoroughly evaluated using DSC. Increasing rates shifted peaks melt crystallization to lower temperatures while fusions almost unaffected. TiO2 hindered PBT rates, i.e., CMAX K’ acquired, in general, crystallinity degree (Xc) was 4% higher which is marginal error. Pseudo-Avrami Mo models applied evaluate kin...

The crystallization of undercooled Pd43Ni10Cu27P20 melts is studied under isothermal conditions and at constant heating and cooling rates. Investigations are carried out by fluxing the melt with B2O3 and without any fluxing material. The isothermal experiments allow us to determine the complete time–temperature-transformation diagram with a minimum crystallization time of about 200 s for the fl...

For the case of paracetamol, we show how terahertz time-domain spectroscopy can be used to characterize the solid and liquid phase dynamics. Heating of supercooled amorphous paracetamol from 295 K in a covered sample under vacuum leads to its crystallization at 330 K. First, form III is formed followed by the transformation of form III to form II at 375 K, to form I at 405 K, and finally meltin...

Advances in experimental techniques and in theoretical models have improved our understanding of protein crystallization. However, they have also left open questions regarding the protein phase behavior and self-assembly kinetics, such as why (nearly) identical crystallization conditions can sometimes result in the formation of different crystal forms. Here, we develop a patchy particle model w...
