Non-Isothermal Crystallization Kinetics of Poly(Butylene Terephthalate)/Silica Nanocomposites

open access: yes, 2009
Poly(butylene terephthalate)/silica nanocomposites were prepared by in situ polymerization of terephthalic acid, 1,4-butanediol and silica. Transmission electronmicroscopy (TEM) was used to examine the quality of the dispersion of silica in the PBT ...

Kinetics of Non-Isothermal and Isothermal Crystallization in a Liquid Crystal with Highly Ordered Smectic Phase as Reflected by Differential Scanning Calorimetry, Polarized Optical Microscopy and Broadband Dielectric Spectroscopy

open access: yesCrystals, 2019
The kinetics of the non-isothermal and isothermal crystallization of the crystalline smectic B phase (soft crystal B, SmBcr) in 4-n-butyloxybenzylidene-4′-n′-octylaniline (BBOA) was studied by a combination of differential scanning ...

Influence of low contents of cellulose nanocrystals on the crystallization behavior of biobased Poly(propylene 2,5-furandicarboxylate)

open access: yesGiant
To address the slow crystallization problem of poly(propylene 2,5-furandicarboxylate) (PPF), fully biobased PPF/cellulose nanocrystals (CNC) composites were prepared via a solution and casting method in this work at low CNC contents. The influence of CNC

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

open access: yesAdvanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Comparative study of thermal stability and crystallization kinetics between melt-spun and bulk Pd77.5Cu6Si16.5 metallic glasses

open access: yesJournal of Materials Research and Technology, 2022
A comparative study on the thermal stability and kinetics of crystallization of both melt–spun and bulk Pd77.5Cu6Si16.5 metallic glasses was performed. Rapidly quenched Pd77.5Cu6Si16.5 ribbon and as–cast bulk metallic glass (BMG) sample were produced by ...

Isothermal and non-isothermal crystallization kinetics of polyethylene terephthalate: Mathematical modeling and experimental measurement

open access: yes, 1998
Results obtained by differential scanning calorimetry have been used to develop a macro-kinetic model for the crystallization behavior of semicrystalline polymeric materials. Our model, which takes into account the effects of induction time, final degree

The Effect of Hydrophilic Headgroup Chemistry on Peptoid‐Directed Mineralization of CaCO3

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic peptoids alter the pathway and outcome of calcium carbonate crystallization, which progresses through amorphous calcium carbonate (ACC) to vaterite to calcite rhombs in the absence of peptoids. In contrast, amine‐terminated peptoids produce vaterite disks and carboxyl‐terminated peptoids produce calcite mesocrystals.
