Inorganic composition and filler particles morphology of conventional and self-adhesive resin cements by SEM/EDX
(Wiley-blackwellHobokenEUA, 2012)
New organic-inorganic hybrid composites based on cellulose nanofibers and modified Laponite
(2018-10-01)
The combination of cellulosic materials and clays, such as Laponite, can provide composites with superior optical and mechanical properties compared to pristine cellulose. Synthetic clays can also be used as a host matrix ...
Uniaxially aligned ceramic nanofibers obtained by chemical mechanical processing
(Elsevier B.V., 2014-08-15)
For this study, we investigated a simple method to generate well aligned nanofibers over large areas using an organic polymer stretched over the substrate surface With this method, ZnO and CuO 3D parallel nanowire arrays ...
Redox potentials and diffusion of lithium in lamellar compounds
(Taylor and Francis Ltd., 2001)
Thermodynamic and dynamic properties of intercalation products of lithium into MoS2 are strongly determined by the coordination of lithium in the interlaminar spaces. Lithium redox potentials as well as lithium diffusion ...
Organic and inorganic sources of zinc, copper and selenium in diets for dairy cows: intake, blood metabolic profile, milk yield and composition
(REVISTA BRASILEIRA ZOOTECNIAVICOSA, 2012)
The present study was carried out with the objective of evaluating the effects of feeding dairy cows with organic or inorganic sources of zinc (Zn), copper (Cu) and selenium (Se) on blood concentrations of these minerals, ...
Determination of inorganic arsenic in Argentinean rice by selective HGAAS: Analytical performance for paddy, brown and polished rice
(Academic Press Inc Elsevier Science, 2020-08)
Inorganic As (iAs) species require strict monitoring in foodstuff due to their toxicity. Rice is of particular concern, with recent legislations establishing limits for these species. In this work we develop a method based ...
NMR study of ion-conducting organic-inorganic nanocomposites poly(ethylene glycol) - Silica - LiClO4
(Amer Chemical Soc, 2000-02-22)
Hybrid organic-inorganic ionic conductors, also called ormolytes, were obtained by dissolution of LiClO4 into silica/poly(ethylene glycol) matrices. Solid-state nuclear magnetic resonance (NMR) was used to probe the inorganic ...

Composite Films Based on Silver-Zeolite/Polymer as Efficient Antifungals
(Wiley, 2020-09)
This work analyzes the preparation and antifungal behavior of composite films formed by a mixed matrix of Ag-zeolite crystals immobilized in a continuous polymer phase. The physicochemical qualities of films prepared with ...
