Time-of-flight neutron powder diffraction data have been measured from ∼90 mol% deuterated isotopologues of Na2MoO4·2H2O and Na2WO4·2H2O at 295 K to a resolution of sin (θ)/λ = 0.77 Å(-1). The use of neutrons has allowed refinement of structural parameters with a precision that varies by a factor of two from the heaviest to the lightest atoms; this contrasts with the X-ray based refinements whe...

Fe3O4 and ZnxFe3-xO4 pure and doped magnetite magnetic nanoparticles (NPs) were prepared in aqueous solution (Series A) or in a water-ethyl alcohol mixture (Series B) by the co-precipitation method. Only one ferromagnetic resonance line was observed in all cases under consideration indicating that the materials are magnetically uniform. The shortfall in the resonance fields from 3.27 kOe (for t...

To satisfy the needs of rapidly growing applications, Li-ion batteries require further significant improvements of their key properties: specific energy and power, cyclability, safety and costs. The first generation of cathode materials for Li-ion batteries based on mixed oxides with either spinel or rock-salt derivatives has already been widely commercialized, but the potential to improve the ...

Herein, we demonstrate a novel and simple two-step process for preparing LiCoO2 nanocrystals by using a Prussian blue analogue Co3[Co(CN)6]2 as a precursor. The resultant LiCoO2 nanoparticles possess single crystalline nature and good uniformity with an average size of ca. 360 nm. The unique nanostructure of LiCoO2 provides relatively shorter Li(+) diffusion pathways, thus facilitating the fast...

Deposition of amyloid-β (Aβ) peptide leads to amyloid plaques that together with tau deposits characterize the brains of patients with Alzheimer's disease (AD). In modeling this pathology, transgenic animals such as the APP23 strain, that expresses a mutant form of the amyloid precursor protein found in familial cases of AD, have been instrumental. In previous studies, we have shown that repeat...

The temperature variation of magnetic anisotropy and coercive field of magnetoelastic manganese-substituted cobalt ferrites CoMnxFe2−xO4 with 0 x 0.6 was investigated. Major magnetic hysteresis loops were measured for each sample at temperatures over the range 10–400 K, using a superconducting quantum interference device magnetometer. The high-field regimes of the hysteresis loops were modeled ...

The K-ZnxCo3-xO4 catalyst supported on α-Al2O3 for N2O decomposition was investigated in terms of its resistance towards typical contaminants (O2, H2O, and NO) present the nitric acid plant tail gases. synthesized laboratory-scale thoroughly characterized by means X-ray μ-tomography, XRF, XRD, SEM/TEM/EDX. impact such as O2, NO conversion examined quantified kinetic thermodynamic modeling. mech...

Industrial catalysts usually encounter great challenges in Cl· deactivation, toxic by-products generation, and stability with a long running operation for catalytic oxidation of chlorinated volatile organic compounds (CVOCs). In this research, spinel-type oxides transition metal substituted as active supported on cordierite (Crd) was identified to degradation chlorobenzene (CB). The Cu1.4Mn1.6O...

Lanthanum substitution on spinel Nano particles has a significant repercussion the several features of materials. Sol–gel (auto-ignition) allowed for rare earth lanthanum ion (La3+) ferrite with composition SrLaxFe2-xO4 (where 0.00 ≤ x 0.10). As result base’s presence, systems structural, magnetic, electrical, and magnetic properties are all modified. X-ray diffraction (XRD) assessed structural...
