Molecular dynamics simulation for polyethylene crystallization: Effect of long chain branches [PDF]
Polyolefins Journal, 2021 The influence of long branches on crystallization behavior has been studied by means of molecular dynamics simulations. Using two systems: polyethylene (PE) with long branches (LCB-PE) and PE without long branches (linear-PE) with the same molecular ...

Optimal Control for non–isothermal crystallization of polymers [PDF]
PAMM, 2005 AbstractIn this paper an optimal control problem for polymer crystallization is investigated. The crystallization is described by a non–isothermal Avrami–Kolmogorov model. The boundary temperature serves as control variable. The cost functional takes the spatial variation of the crystallinity and the final degree of crystallization into account.

Crystallization kinetics of glassy Se90In10-xAgx alloys: Observation of Mayer-Neldel rule [PDF]
Processing and Application of Ceramics, 2016 Glassy alloys of Se90In10-xAgx were prepared using melt quenching technique. Non-isothermal differential scanning calorimetric (DSC) studies were done on Se90In10-xAgx (x = 0, 2, 4, 6, 8 at.%) glassy alloys at four different heating rates (β = 5, 10, 15,
