Influence of addition of calcium oxide on physicochemical properties of Portland cement with zirconium or niobium oxide
(2015)
Context: Calcium oxide (CaO) may be added to mineral trioxide aggregate (MTA) or Portland cement (PC) to improve physicochemical and biological properties. Aims: To evaluate the physicochemical properties of PC associated ...
Transparent nanostructured cellulose acetate films based on the self assembly of PEO-b-PPO-b-PEO block copolymer
(2017-06-01)
In this study fabrication and characterization of transparent nanostructured composite films based on cellulose triacetate (CTA) and poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (EPE) triblock copolymer ...
Enhancement in the oxidative stability of green peas by Ilex paraguariensis addition in a blanching process before their refrigerated and frozen storage
(Elsevier Science, 2018-05)
Green peas have a short shelf-life because their unsaturated fatty acids are exposed to oxidative damage induced by pro-oxidant enzymes leading to organoleptic changes and nutritional quality losses. Blanching (BL) is a ...
Regioregular improvement on the oxidative polymerization of poly-3-octylthiophenes by slow addition of oxidant at low temperature
(WILEY-BLACKWELLMALDEN, 2012)
Many pathways can be used to synthesize polythiophenes derivatives. The polycondensation reactions performed with organometallics are preferred since they lead to regioregular polymers (with high content of heat-to-tail ...
