Chitosan coated-phosphorylated starch films: Water interaction, transparency and antibacterial properties
(Elsevier Science, 2018-08-26)
Since there is a current need for developing biodegradable mulch films that keep the advantages of those manufactured with polyethylene but offering earlier biodegradation, new starch-based formulations were proposed and ...
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 ...
Avoiding coupling fluid-sample interaction in confocal Raman depth s profiling with immersion objectives
(Soc Applied Spectroscopy, 2008-07-01)
A strategy based on the use of a protective coating as a separating medium to prevent sample-coupling fluid direct contact when one performs depth profiling by Confocal Raman microspectroscopy (CRM) with immersion objectives ...
Confocal Raman Microspectroscopy: A Non-Invasive Approach for in-Depth Analyses of Polymer Substrates
(Wiley VCH Verlag, 2009-04)
We present a simple approach that avoids the problem of coupling fluid-sample interaction in confocal Raman depth-profiling with immersion objectives. We use a thin protective medium (polyethylene film) that preserves the ...
Quality parameters of packaged refrigerated apple cubes in orange juice
(Elsevier Science, 2002-03)
The quality of apple cubes (Red Delicious and Granny Smith) maintained in pasteurised or fresh orange juice with sucrose and chemical preservatives: acidulants (citric and ascorbic acids) and potassium sorbate or sodium ...
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 ...
Synthesis of polyethylene/silica-silver nanocomposites with antibacterial properties by in situ polymerization
(Pergamon-Elsevier Science Ltd, 2018-09-09)
Synthesis of polyethylene/silica-silver nanocomposites (PE/SiAg) by in situ polymerization with supported and non-supported catalysts was achieved using the Cp2ZrCl2/MAO catalytic system. Silica-silver nanoparticles (SiAg) ...
Photocatalytic Efficiency Tuning by the Surface Roughness of TiO2 Coatings on Glass Prepared by the Doctor Blade Method
(Wiley Blackwell Publishing, Inc, 2021-01)
A set of opaque films were prepared with Degussa P25® or Hombikat UV100® TiO2 powders by the doctor blade method on glass slides with different compositions of polyethylene glycol of 20 kDa (PEG20), and they were characterized ...
The effect of temperature on microbial growth in apple cubes packed in film and preserved by use of orange juice
(Wiley Blackwell Publishing, Inc, 2004-11)
Red delicious apple cubes were packed in fresh orange juice containing chemical preservatives (citric and ascorbic acid, potassium sorbate) and covered with plastic films of different gas permeabilities (polyethylene and ...
Compression molded LLDPE films loaded with bimetallic (Ag-Cu) nanoparticles and cinnamon essential oil for chicken meat packaging applications
(Elsevier Science, 2018-07)
This study describes the development of bioactive linear low-density polyethylene (LLDPE) films, blended with cinnamon essential oil (CEO), and selected concentrations of silver-copper (Ag-Cu) nanoparticles (NPs), and ...
