The aim of this study was to prepare, characterize, and determine the in vitro anticancer effects platinum-doped magnesia (Pt/MgO) nanoparticles. chemical compositions, functional groups, size nanoparticles were determined using X-ray diffraction, Fourier transform infrared spectroscopy, energy dispersive transmission electron microscopy, scanning microscopy. Pt/MgO cuboid nanosize range 30–50 ...

UNLABELLED A one-step process for the production of nanoparticles presenting advanced magnetic properties can be achieved using vapor condensation. In this article, we report on the fabrication of Fe particles covered by a uniform MgO epitaxial shell. MgO has a lower surface energy than Fe, which results in a core-shell crystal formation. The particles satisfy a few of technical requirements fo...

Antibiotic resistance has impelled the research for new agents that can inhibit bacterial growth without showing cytotoxic effects on humans and other species. We describe the synthesis and physicochemical characterization of nanostructured ZnMgO whose antibacterial activity was compared to its pure nano-ZnO and nano-MgO counterparts. Among the three oxides, ZnO nanocrystals-with the length of ...

The liquid phase oxidation of cyclohexane was undertaken using Au/MgO and the reaction mechanism was investigated by means of continuous wave (CW) EPR spectroscopy employing the spin trapping technique. Activity tests aimed to determine the conversion and selectivity of Au/MgO catalyst showed that Au was capable of selectivity control to cyclohexanol formation up to 70%, but this was accompanie...

Abstract Syngas can be produced from biomethane via Partial Oxidation of Methane (POM), being an attractive route since it is ecofriendly and sustainable. In this work, catalysts Ni supported on MgO–ZrO 2 solid solutions, prepared by a one-step polymerization method, were characterized HRTEM/EDX, XRD, XPS, H -TPR, in situ XRD. All catalysts, including Ni/ZrO Ni/MgO as reference, tested for POM ...

Herein, we report a procedure for separating and preconcentrating antibiotics from human serum using novel adsorbent of magnetic graphene oxide (MGO) cadmium sulfide (CdS) nanoparticles. The (MGO@CdS) was characterized Fourier transformed infrared spectrometry (FT-IR), energy dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM). effective parameters extracti...

Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nano size, which drastically changes the chemical, physical and optical properties of metals. The extremely small size of nanoparticles help them to occupy a greater surface area and hence a better accessibility and targeted action. Nanoparticles can overcome existing drug r...

Three methods were developed for the synthesis of bismuth-ceramic nanocomposites, which are of interest due to possible use as thermoelectric materials. In the first synthetic method, high energy ball milling of bismuth metal with either MgO or SiO 2 was found to produce nanostructured bismuth dispersed on a ceramic material. The morphology of the resulting bismuth depended on its wetting behav...
