Lime (Citrus aurantifolia) is one of the most extensively exported agricultural products from Indonesia. Citric acid and ascorbic content limes such carbon-rich fruits that a suitable source for Carbon Quantum Dots (CQDs) synthesis. CQD synthesized by relying on natural carbon precursors lime more environmentally friendly approach in present research, CQDs this research will be used as an addition to ZnO hydrothermal method order enhance photocatalytic activity. Corresponding results,...
We have studied the magnetodieletric coupling of polycrystalline samples spinels MCr(2)O(4) (M = Mn, Co and Ni). Dielectric anomalies are clearly observed at onset magnetic spiral structure (T(s)) 'lock-in' transition (T(f)) in MnCr(2)O(4) CoCr(2)O(4), also canted NiCr(2)O(4). The strength magnetodielectric this system can be explained by spin-orbit coupling. Moreover, dielectric response an applied field scales with square magnetization for all three samples. Thus, state appears to...
We give general arguments that show the linear magnetoelectric effect in antiferromagnetic materials gives rise to a magnetocapacitance anomaly---a divergence of dielectric constant at magnetic ordering temperature ${T}_{N}$ appears an applied field. The measurement magnetodielectric response thus provides definitive and experimentally accessible method recognize materials, circumventing experimental difficulties often involved measuring electric polarization. confirm this result using...
We have explored a new strategy to discover materials with large resistive or capacitive responses magnetic fields by synthesizing EuMO2N (M = Nb, Ta) perovskites that combine ferromagnetic order of S 7/2 Eu2+ spins possible off-center distortions the d0 M5+ cations enhanced covalent bonding N. EuNbO2N shows colossal magnetoresistances at low temperatures and giant magnetocapacitance. However, latter response originates from microstructural effect rather than an intrinsic multiferroism.
In this study, we report the synthesis of magnetite/silica nanocomposites and their structural functional groups, magnetic properties, morphology, antimicrobial activity, drug delivery performance. The X-ray diffraction characterization showed that magnetite formed a spinel phase silica an amorphous phase. particle sizes increased from 8.2 to 13.2 nm with increasing content, particles were observed be superparamagnetic. tended agglomerate based on scanning electron microscopy images....
To date, the search for creating stable ferrofluids with excellent properties biomedical application is one of challenging scientific and practical investigations.

Aurivillius phase Bi2LaNb1.5Mn0.5O9, derived from ferroelectric PbBi2Nb2O9 by simultaneous substitution of the A-site and B-site cations, was synthesized using a molten-salt method. Here, we discuss structure-property relationships in detail. X-ray neutron diffraction show that Bi2LaNb1.5Mn0.5O9 adopts an A21am orthorhombic crystal structure. Rietveld refinement analysis, supported Raman spectroscopy, indicates Bi3+ ions occupy bismuth oxide blocks, La3+ perovskite A-site, Nb5+/Mn3+ B-site....
