Molecular dynamics simulation for polyethylene crystallization: Effect of long chain branches [PDF]

open access: yesPolyolefins 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 ...

Crystallization kinetics of glassy Se90In10-xAgx alloys: Observation of Mayer-Neldel rule [PDF]

open access: yesProcessing 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,

Determination of non-isothermal crystallization rate constant for pseudo-experimental calorimetric data

open access: yesMaterials Research, 2009
In the present work, non-isothermal crystallization data in the form of heat flow vs. temperature curves were generated using the Nakamura Model and its typical parameters reported in the literature for polypropylene. The values obtained for these curves

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

open access: yesAdvanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...
