Lemon essential oil desorption from polypropylene/talc nanocomposite films
(Springer, 2016-12-11)
A phenomenological analysis on desorption mechanism of lemon essential oil in semicrystalline polymer nanocomposites is performed. Films made with polypropylene and talc nanoparticles obtained by blown extrusion are used ...
Crystalline morphology of thermoplastic starch/talc nanocomposites induced by thermal processing
(Elsevier, 2019-06)
A structural study about the changes induced by plasticization of native corn starch was carried out in this work. The influence of talc nanoparticles presence during starch thermal processing was also evaluated. Macroscopic ...
Mechanical properties of polypropylene/talc composites: Role of the mineral morphology and particle surface modification
(Nova Science Publishers, 2013)
Talc filled Polypropylene (PP) is a very used versatile composite as it combines a relative good performance with easy processability and low cost. Talc addition strongly affects PP properties mainly by their effect on ...
Uso de talco nacional como aditivo adsorvente de piches e materiais pegajosos no processo de fabricação do papel
(Universidade Federal de Minas GeraisUFMG, 2003-02-14)
The subject of this study is the use of Brazilian talc as an additive for pitch and stickies control in paper industry, including technical and economical questions shared by raw material suppliers, as well as industrial ...
Comparative analysis of crystallization behavior induced by different mineral fillers in polypropylene nanocomposites
(SAGE Publications, 2020-06-04)
A comparative analysis of crystallization behavior induced by several mineral fillers in polypropylene nanocomposites was performed. Morphological changes and thermal properties of nanocomposites were evaluated, considering ...
Phase transformations of a talc ore under heated chlorine atmosphere
(Elsevier, 2013-02-20)
The effect of Cl2 on the phase transformations of the minerals present in a talc (Mg3Si4O10(OH)2) unpurified with clinochlore (Mg5Al2Si3O10(OH)8), magnesite (MgCO3), dolomite (MgCa(CO3)2), hematite (Fe2O3) and pyrite (FeS2) ...
Acute inflammatory response secondary to intrapleural administration of two types of talc
(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2010)
Intrapleural instillation of talc has been used in the treatment of recurrent pleural effusions but can, in rare instances, result in respiratory failure. Side-effects seem to be related to composition, size and inflammatory ...
Insecticidal Activity of the Granulosis Virus in Combination with Neem Products and Talc Powder Against the Potato Tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)
(ENTOMOLOGICAL SOC BRASILLONDRINA,, 2012)
The potato tuberworm Phthorimaea operculella (Zeller) is an important agricultural pest that causes significant economic losses to potato growers worldwide. The addition of an effective method of biological control for the ...
Asbestiform and non-asbestiform morphologies in a talc and vermiculite mine from the province of Córdoba (Argentina): a case study
(Springer, 2017-09)
In this work, a talc and vermiculite mine from the province of Córdoba (Argentina) was investigated with special emphasis on the occurrence of asbestiform and non-asbestiform phases. The meta-ultramafic rock was studied ...
