To improve the image quality of photon-counting energy-dispersive X-ray computed tomography (CT) and to reduce the incident dose for the object, we have developed a low-dose low-scattering CT scanner with high-spatial and -energy resolutions using a cooled cadmium telluride (CdTe) detector. X-ra...

The first quaternary nitride telluride with trivalent gadolinium, Cs2Gd6N2Te7, was obtained by the reaction of metallic gadolinium with cesium azide, elemental tellurium, and gadolinium trichloride as well as cesium chloride as flux at 900 °C for 7 days in evacuated silica tubes. Single crystal...

A linear cadmium telluride (CdTe) detector is useful for carrying out energy-discrimination X-ray imaging, including computed tomography (CT). To perform enhanced gadolinium K-edge CT, we used an oscillation-type linear CdTe detector with an energy resolution of 1.2 keV. CT is performed by repea...

In this work, maximum enhancement in room temperature humidity sensing response of cadmium ferrite (CF) due to substitution of nickel ion in it, to form nickel substituted cadmium ferrite (NSCF) by sol-gel auto combustion method is presented. The shift in vibration frequency corresponding to oct...

Shrinking core model is widely applied to describe the reduction of iron ore pellets, but limited to the illustration on powder sample. The reduction of powder materials is commonly observed in blast furnace production but has been rarely investigated. In this study, thermal kinetics analysis wa...

Nanosized MnZn ferrite particles, with narrow size distribution, regular morphology and high saturation magnetization have been synthesized via a modified hydrothermal method. This modified hydrothermal method involves a chemical co-precipitation of hydroxides under a vacuum condition using pota...

MnFe2O4/Graphene and ZnFe2O4/Graphene Nanocomposites (MFG & ZFG) were synthesized by solvothermal route and further tested as promising electrocatalyst towards Hydrogen Evolution Reaction (HER).

Three-dimensional (3D) honeycomb-like structured graphene (HSG)-supported ternary K-promoted magnesium ferrite catalysts (K-MgFe/HSG) are prepared and evaluated in Fischer–Tropsch synthesis to the lower olefins (FTO). The catalysts bear interconnected mesoporous-macroporous framework of graphen...

Microbial denitrification in agricultural soil is a major contributor to the terrestrial production of the greenhouse gas nitrous oxide (N2O). Iron oxides play influential roles in both biochemical and chemical pathways that produce N2O; however, their role in the denitrifying bacterial communit...

During the last decade much attention has been devoted to multiferroic materials due to the simultaneous presence of ferromagnetic and ferroelectric properties. Among various materials bismuth iron oxide is a promising candidate but bismuth iron oxide exhibits antiferromagnetic behavior that lim...
