Comparison of predicted and experimental DSC curves for vegetable oils [PDF]

open access: yes, 2012
We compare experimental and predicted differential scanning calorimetry (DSC) curves for palm oil(PO), peanut oil (PeO) and grapeseed oil (GO). The predicted curves are computed from the solid–liquid equilibrium modelling and direct minimization of the ...

Investigating the Physical State of Polymer Electrolyte: Influence of Temperature and LiTFSI Concentration on the Phase of the Different States of the Polymer Electrolyte PEO-LiTFSI

open access: yesECS Advances, 2023
A critical analysis of the physical state {solid or liquid state} of the PEO-LiTFSI system was investigated in this study. The findings show one crystallite type in PEO and four in LiTFSI.

Evolution of PEO coatings on AM50 magnesium alloy using phosphate-based electrolyte with and without glycerol and its electrochemical characterization

open access: yesJournal of Magnesium and Alloys, 2020
PEO coatings were synthesized from phosphate-based (bP-PEO) and glycerol added phosphate-based (gP-PEO) electrolytes with different processing times. For both bP-PEO and gP-PEO coatings treated with different processing time its morphology, elemental and

Fabrication of poly(lactic acid) – poly(ethylene oxide) electrospun membranes with controlled micro to nanofiber sizes [PDF]

open access: yes, 2012
Biodegradable poly(L-lactide acid) (PLLA) nanofiber membranes were prepared by electrospinning of PLLA and poly(ethylene oxide) (PEO). The selective removal of PEO by water allows to obtain smaller fiber diameters and to increase the porosity of the ...
