Distinct Roles for Bacterial and Fungal Communities During the Curing of Vanilla

open access: yesFrontiers in Microbiology, 2020
Vanilla produces aroma after curing. There were a few reports about the possible involvement of microorganisms during the curing process. Bacterial and fungal community was analyzed to explore the distinct roles.

New System to Determine the Evolution of the Dynamic Young’s Modulus from Early Ages in Masonry Mortars

open access: yesApplied Sciences, 2020
This work presents a new method to determine the evolution of the dynamic Young’s modulus (MOE) from small mechanical disturbances caused by cement mortar samples and whose value is collected using a low-cost Arduino accelerometer.

Sequential curing of thiol-acetoacetate-acrylate thermosets by latent Michael addition reactions [PDF]

open access: yes, 2017
Thiol-acetoacetate-acrylate ternary dual-curing thermosets were prepared by a sequential process consisting of thiol-Michael addition to acrylates at room temperature followed by Michael addition of acetoacetates to acrylates at moderately elevated ...

Non-destructive evaluation of an infusion process using capacitive sensing technique [PDF]

open access: yes, 2016
In this study, a capacitive sensing based non-destructive evaluation technique is applied to a vacuum assisted resin infusion process for the fabrication of glass fibre reinforced composites, as such different steps of the fabrication process (the ...

Degree of cure‐dependent modelling for polymer curing processes at small strains [PDF]

open access: yesPAMM, 2013
AbstractIn this paper, a thermodynamically consistent small strain constitutive model is formulated that is directly based on the degree of cure, a key parameter in the curing (reaction) kinetics. The new formulation is also in line with the earlier proposed hypoelastic approach, cf. Hossain et al., 2010.

Use of Parameter Estimation for Stereolithography Surface Finish Improvement [PDF]

open access: yes, 2005
In order to improve Stereolithography (SLA) surface finish, a systematic approach based on estimation of process parameters is needed. In this paper, the exposure on a desired SLA build surface is formulated as a function of process parameters.

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]

open access: yes, 2019
The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.

In situ monitoring of epoxy resin curing process: Using glass transition as a bridge

open access: yesPolymer Testing, 2023
Dielectric analysis (DEA) is an effective method for monitoring the curing process of epoxy resin (EP) in situ, but the influence of curing temperature on the measurement results limits the application of DEA in curing process monitoring with variable ...

Phenomenological characterization of sequential dual-curing of off-stoichiometric "thiol-epoxy" systems: Towards applicability [PDF]

open access: yes, 2017
An extensive characterization of a sequential dual-curing system based on off-stoichiometric “thiol-epoxy” mixtures was carried out using thiol compounds of different functionality.
