New bio-based materials obtained by thiol-ene/thiol-epoxy dual curing click procedures from eugenol derivates [PDF]

open access: yes, 2017
Novel bio-based and dual-curable thermosets were prepared from eugenol derivatives. The curing sequence combined two click reactions, a photoinduced radical thiol-ene reaction followed by a thermally activated thiol-epoxy reaction.

Research of Wood-Polymer Compositions of DMTA Methods

open access: yesInternational Journal of Science and Society, 2020
The article presents the results of polymer-wood composites, as well as the excretion of tritium woods and leaves. The base of the composite was made of thermoplastic polypropylene. Three composites prepared by the volume of filling content (25, 50 and 70%) and the various fractions of the used slags were prepared for research.

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

open access: yesMacromolecular Materials and Engineering, EarlyView.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.

Study of (SSD) Biscuit Baking by Dynamic Thermal Analyses (DMTA, DSC, TGA) [PDF]

open access: yes, 1998
The baking process of sheeted short dough (SSD) biscuits involves the transformation from a viscoelastic dough into a cellular solid, with a final texture. This process is induced by the expansion of the material submitted to the vaporization of water and gases from leavening powders.

Determination of the Linear Viscoelastic Material Behaviour of Interlayers with Semi-Crystalline Structures

open access: yesChallenging Glass Conference Proceedings, 2022
The temperature dependent linear viscoelastic material behaviour of the most commonly used interlayer PVB is typically determined by means of Dynamic-Mechanical-Thermal-Analysis (DMTA).

The use of a DMT to monitor the stability of the slopes of a clay exploitation pit in the Boom clay in Belgium [PDF]

open access: yes, 2015
In Belgium the Boom Clay is a well known overconsolidated clay formation. This Tertiary clay, with the same geological origin as the London Clay, is used for the fabrication of bricks, roofing tiles. In the article is described how the DMT can be used to

Sustainable Carbon Fiber Composites Based on Recyclable Bio‐Based Vanillin Thermoset Polymers

open access: yesPolymer Composites, EarlyView.
Development of composite materials made from a bio‐based and mechanically recycled vitrimeric polymer matrix. ABSTRACT Although bisphenol A (BPA) is the most used organic compound in the production of thermosets for composite materials, there has been an urgent scientific concern to eliminate it in the last years due to the environmental issues raised ...
