Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Mechanical properties and thermal shock resistance of anorthite ceramics obtained by slip casting
(Elsevier Ltd., 2024)
Anorthite ceramics (CaAl2Si2O8) was obtained by slip casting of water suspension of kaolin (Al2O3·2SiO2·2H2O) and CaCO3 as a source of CaO. A relative density of 87 % of the theoretical density was achieved after a 3-h-long ...
Karakterizacija liofilizovanih ekstrakata majčine dušice (thymus serpyllum l.) I njihova antioksidativna aktivnost
(Faculty of Technology, Zvornik, 2017)
Budući da je većinu aktivnih komponenata biljaka nemoguće sintetisati u
laboratoriji, najbolja opcija je njihova ekstrakcija iz prirodnih izvora. U
datom eksperimentu, korišćena je herba majčine dušice (Thymus serpyllum)
