Aging effects in the electrokinetics of colloidal iron oxides.
We analyze in this contribution the effect of aging on the electrokinetic properties of magnetite (Fe(3)O(4)) and hematite (alpha-Fe(2)O(3)). In both cases, high-purity commercial samples and monodisperse synthetic particles were studied. Commercial magnetite showed a rather erratic dependence of its electrophoretic mobility u(e) with the concentration of NaCl. Furthermore, sufficient concentra...
متن کاملFacile and Sustainable Synthesis of Shaped Iron Oxide Nanoparticles: Effect of Iron Precursor Salts on the Shapes of Iron Oxides
A facile and sustainable protocol for synthesis of six different shaped iron oxides is developed. Notably, all the six shapes of iron oxides can be synthesised using exactly same synthetic protocol, by simply changing the precursor iron salts. Several of the synthesised shapes are not reported before. This novel protocol is relatively easy to implement and could contribute to overcome the chall...
متن کاملOptimal Iron Oxides for Obtaining Hexaferrites
Presently, the ferrites industry consumes large amounts of iron osides obtained by spray roasting of steel pickling liquors. The aim of this paper is to propose the synthesis of optimal iron osidcs by oxyprecipitation of steel pickling liquors in order to obtain Bahexafenite wit11 high magnetic properties using the ceramic process. As a raw material. i t was used sulphuric liqoors with iron con...
متن کاملEffect of aging on saccularfunction
Background :Aging can cause loss of balance, which may lead to physical and psychological problems. As the role of the otolith organs in maintaining postural stability has been emphasized in recent years, the present study investigated the effect of aging on saccular function using cervical vestibular evoked myogenic potentials (cVEMP). Methods : The participants were assigned into two grou...
متن کاملEffect of alumina on photocatalytic activity of iron oxides for bisphenol A degradation.
To study the photodegradation of organic pollutants at the interface of minerals and water in natural environment, three series of alumina-coupled iron oxides (Al(2)O(3)-Fe(2)O(3)-300, Al(2)O(3)-Fe(2)O(3)-420, and Al(2)O(3)-Fe(2)O(3)-550) with different alumina fraction were prepared and characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halender (BJH), and...
