Supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with insecticidal terpene ketones: Impregnation yield, crystallinity and mechanical properties assessment
(Elsevier Science, 2017-06)
In this contribution, supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with two insecticidal terpene ketones (thymoquinone and R-(+)-pulegone) is investigated, as a strategy to enhance the ...
Carvone-loaded LDPE films for active packaging: Effect of supercritical CO2-assisted impregnation on loading, mechanical and transport properties of the films
(Elsevier Science, 2018-03)
In this work, low density polyethylene (LDPE) films were loaded by scCO2-assisted impregnation with R-(−)-carvone, the main component of M. spicata and A. polystachya essential oils with antimicrobial and insecticidal ...
Supercritical carbon dioxide assisted impregnation of eugenol into polyamide fibers for application as a dental floss
(Elsevier B.V., 2019-07)
Supercritical CO2-assisted impregnation was applied to incorporate eugenol into polyamide fibers in order to develop a solvent-free material with antimicrobial properties to be potentially applied as dental floss. Impregnation ...
Active LDPE films loaded with biopesticides by supercritical CO2-assisted impregnation for stored grain protection
(Elsevier, 2018-12)
The aim of this contribution was to obtain bioactive materials for stored grain protection and food preservation, by incorporating a biopesticide (1-octen-3-ol) in polyethylene (LDPE) films using supercritical CO2–assisted ...
Mass transfer kinetics of CO2 and eugenol in the supercritical impregnation of polyamide fibers: Experimental data and modeling
(Elsevier Science, 2020-12)
In this work, mass transfer kinetics of CO2 and eugenol into polyamide 6 (PA6) fibers under supercritical conditions were investigated in the context of the development of a functional dental floss for dental care applications ...
Study of chia oil microencapsulation in soy protein microparticles using supercritical CO2-assisted impregnation
(Elsevier, 2020-09)
Microencapsulation of chia oil in soy protein microparticles was achieved using supercritical CO2-assisted impregnation, an alternative green technology. The effect of the process variables on retention and encapsulation ...
An insecticide formulation of terpene ketones against Sitophilus zeamais and its incorporation into low density polyethylene films
(Elsevier, 2017-08)
The use of active natural compounds derived from plants appears as an interesting alternative for pest control in stored products. In this study, the fumigant toxicity of several terpene ketones against maize weevil ...
Mass transfer kinetics and diffusion coefficient estimation of bioinsecticide terpene ketones in LDPE films obtained by supercritical CO2-assisted impregnation
(John Wiley & Sons Inc, 2017-12)
Release kinetics of thymoquinone and R-(+)-pulegone impregnated in low-density polyethylene (LDPE) films into air and the effect of supercritical CO2-assisted impregnation process on the diffusional properties of these ...
Co/MCM41 catalyst in the COProx reaction prepared by supercritical CO2 reactive deposition
(Elsevier Science, 2017-02)
Co/MCM41 catalyst with 4.3 wt % Co (Co/sc) has been prepared by supercritical CO2 reactive deposition (‘scfrd’) and characterized by different physicochemical techniques. This synthesized method was compared with others ...
Valorization of an agroindustrial soybean residue by supercritical fluid extraction of phytochemical compounds
(Elsevier Science, 2019-01)
The present study proposes the valorization of an agroindustrial residue (expeller) obtained from soybean oil extraction by pressing operation. Two expeller samples, S1 and S2, were processed to obtain extracts by supercritical ...
