Magnetoelectric reduction of chromium(VI) to chromium(III)

چکیده
Toxic heavy-metal pollution represents one of the most pressing environmental challenges that humankind faces today. The conventional approaches for removing highly toxic and carcinogenic heavy metals are currently unsuitable practical applications. reduction harmful metals, such as hexavalent chromium (Cr(VI)) into less trivalent Cr(III), has been gaining considerable interest. In response to this, UV light based photocatalysts have comprehensively investigated various problematic metals. However, applications, using a solution can be inefficient owing poor absorption in murky or colored metal contaminated water. Here, we demonstrate wireless magnetic fields induce Core-shell magnetoelectric CoFe2O4@BiFeO3 nano-octahedral particles were fabricated used catalytic Cr(VI) via effect. We conducted trapping experiments propose mechanism behind magnetoelectric-effect reduction. achieved 86% scavenger singlet oxygen. addition, show concomitant degradation an organic pollutant, methylene blue, synergistic manner, where presence blue accelerates Cr(III).

Here we demonstrate electric-field induced magnetic anisotropy in a multiferroic composite containing nickel nanocrystals strain coupled to a piezoelectric substrate. This system can be switched between a superparamagnetic state and a single-domain ferromagnetic state at room temperature. The nanocrystals show a shift in the blocking temperature of 40 K upon electric poling. We believe this is ...

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولMagnetoelectric switching of exchange bias.
The perpendicular exchange bias field, H(EB), of the magnetoelectric heterostructure Cr2O3(111)/(Co/Pt)(3) changes sign after field cooling to below the Néel temperature of Cr2O3 in either parallel or antiparallel axial magnetic and electric freezing fields. The switching of H(EB) is explained by magnetoelectrically induced antiferromagnetic single domains which extend to the interface, where t...
