Revealing of Core Shell Effect on Frequency-Dependent Properties of Bi-based Relaxor/Ferroelectric Ceramic Composites.
(
Nature Research
, 2018 , Article)
In this study, electromechanical characteristics of (1-x) BiNaTiO-xSrTiO (ST26, x = 0.26)/(1-y) BiNaTiO-ySrTiO (ST10, y = 0.1) (matrix/seed) composites were studied. The ST26 (high relaxor phase) and ST10 (a relaxor ...
Polymer chain dynamics in epoxy based composites as investigated by broadband dielectric spectroscopy
(
Elsevier B.V.
, 2016 , Article)
Epoxy networks of the diglycidyl ether of bisphenol A (DGEBA) were prepared using 3,3′- and 4,4′-diaminodiphenyl sulfone isomer crosslinkers. Secondary relaxations and the glass transitions of resultant networks were probed ...

(
Elsevier
, 2017 , Article)
Abstract In this study, magnetic Zinc Ferrite (ZnFe2O4)@TiO2 nanofibers were prepared by low cost and nontoxic route; hydrothermal technique followed by electrospinning process. The prepared magnetic ZnFe2O4@TiO2 nanofibers ...
Health and Safety Concerns: Quantitative Studies of Leaching of Metals from Glazed Surfaces of Traditional Ceramic Potteries
(
Open Science Publishers
, 2017 , Article)
Traditional ceramic wares have been known as a source of heavy metals poisoning. Traditional ceramic potteries may be improperly glazed, and the glaze used to make the pottery may contain over amounts of heavy metals. These ...
Ecotoxicological Assessment of Thermally- and Hydrogen-Reduced Graphene Oxide/TiO₂ Photocatalytic Nanocomposites Using the Zebrafish Embryo Model.
(
MDPI
, 2019 , Article)
Advanced oxidation processes (AOPs) have recently attracted great interest in water pollution management. Using the zebrafish embryo model, we investigated the environmental impacts of two thermally (RGOTi)- and hydrogen ...
