The activation energy determination in non-isothermal conditions for the solid-state phase transformation of 1035 steel

Metalurgija, 2020
The activation energy of solid-state phase transformation for the steel has been evaluated by the isoconversional method. It is demonstrated that the linear fitting is a mathematically invalid procedure that generally invalidates the isoconversional ...

Compositional Time–Temperature–Transformation and Post‐Processing Window Mapping of Epoxy Nanocomposites via Machine Learning

Journal of Applied Polymer Science, EarlyView.
Discrete DSC and rheological data are transformed into continuous compositional Time–temperature–transformation (TTT) diagrams through physics‐informed Gaussian Process Regression. The proposed framework quantitatively predicts post‐gel processing windows across temperature and nanofiller composition, providing a practical route for accelerated design ...

Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties

Macromolecular Rapid Communications, EarlyView.
A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Curing kinetics of two commercial urea-formaldehyde adhesives studied by isoconversional method [PDF]

Hemijska Industrija, 2011
Differential scanning calorimetry (DSC) was used to evaluate the curing kinetics of two commercial urea-formaldehyde (UF) adhesives having different formaldehyde to urea (F/U) ratio of 1.112 (UF1) and 1.086 (UF2). DSC measurements were done in dynamic

Curing Behavior and Structure Reactivity‐Property Relationships in Epoxidized Linseed Oil Thermosets Crosslinked With Biobased Eutectic Hardeners

Journal of Polymer Science, EarlyView.
The curing of epoxidized linseed oil with citric, tartaric, and malic acid–based eutectic hardeners is compared to reveal how acid functionality, hydroxyl content, and molecular geometry govern activation energy, reaction rates, and network rigidity.

Isoconversional Kinetic Analysis of the Combustion of Heavy Hydrocarbons [PDF]

SPE Western Regional Meeting, 2009
Abstract One method to access unconventional, heavy-oil resources is to apply in-situ combustion (ISC) to oxidize in place a small fraction of the hydrocarbon thereby providing heat to reduce oil viscosity and pressure that enhances recovery.

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

Advanced Functional Materials, Volume 36, Issue 53, 2 July 2026.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...
