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 ...
Effect of functionalized silica nanoparticles on the mass transfer process in active PLA nanocomposite films obtained by supercritical impregnation for sustainable food packaging
(Elsevier, 2020-07)
Nanocomposite films based on PLA with 1.0 % w/w silica nanoparticles (NP) and surface-functionalized silica nanoparticles with lactic acid (NP-LA), respectively, were obtained by extrusion process. Subsequently, cinnamaldehyde ...
Cobalt nanoparticles on mesoporous MCM-41 and Al-MCM-41 by Supercritical CO2 Deposition
(Elsevier Science, 2012-01)
CoO and Co3O4 nanoparticles were uniformly dispersed inside mesoporous MCM-41 and Al-MCM-41 supports using supercritical CO2 reactive deposition. This method represents a one-pot reproducible procedure that allows the ...
Solubility of three natural compounds with insecticidal activity in supercritical carbon dioxide: Experimental measurements and predictive modeling with the GC-EoS
(Elsevier Science, 2019-08)
In this work, the solubility of thymoquinone, R-(+)-pulegone and 1-octen-3-ol in supercritical CO 2 is determined in a range of conditions typical of supercritical fluid processes such as extraction, fractionation and ...
Estudo sobre a atividade antifúngica e antioxidante de extratos de própolis obtidos com CO2 supercrítico
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2014)
A própolis é uma substância resinosa produzida pelas abelhas através da coleta de metabólitos secundários da flora e sua composição química é complexa e variada, conferindo a este produto diversas atividades biológicas ...
