magnesium oxide nanotubes of finite length are investigated by the density functional theory (dft) at the b3lyp/6-31g (d) level. the (6, 0) zigzag and (4, 4) armchair of mgo nanotubes were considered and nuclear magnetic resonance properties including isotropic and anisotropic chemical shielding parameters (csi and csa) were calculated for 25mg and 17o atoms of the optimized structures for the ...

Magnesium-sulfur batteries have developed as a new and emerging technology benefiting from high energy density, low cost, reasonable safety, excellent storage due to the natural abundance of electrochemically active materials dendrite formation in magnesium. Here we report various enhancement strategies also focus on using carbon electrodes, coating layers over cathodes, nanotubes, reduced grap...

A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.

background: hypomagnesaemia is one of the main side effects of cisplatin-based chemotherapy regimens in cancer patients. the aim of the current investigation was to evaluate the effect of oral magnesium oxide (mgo) supplementation on cisplatin-induced hypomagnesemia. methods: this parallel-randomized controlled, open label trial was conducted in a hospital of iran university of medical sciences...

Vanadium oxide nanotubes belong to inorganic nanotubes. One inorganic nanotubes (WS2) synthesized in 1992.Vanadium oxide nanotubes discovared by spahr in 1998.Vanadium oxide nanotubes are used in chemical, bio, electronics and catalysts industry. Many applications of these nanotubes have not yet been discovered. Especially when these nanotubes are doped with different elements. The structure of...

This study compared magnesium oxide and magnesium citrate with respect to in vitro solubility and in vivo gastrointestinal absorbability. The solubility of 25 mmol magnesium citrate and magnesium oxide was examined in vitro in solutions containing varying amounts of hydrochloric acid (0-24.2 mEq) in 300 ml distilled water intended to mimic achlorhydric to peak acid secretory states. Magnesium o...

Synthesis of different kinds of nanotubes were considering after the discovery of carbon nanotubes . Lately has been noticed synthesis of vanadium oxide nanotubes. Vanadium oxide nanotubes are made of multilayer scrolls with thick walls built up from several vanadium oxide layers. This compunds be used as catalysts, molecular sieves, absorbents and energy storage devices. In this research study...

Fluorine-doped carbon nanotubes were synthesized using cobalt and silver co-catalyst on magnesium oxide support and their morphological features studied using Raman spectroscopy, energy dispersive spectroscopy (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction spectroscopy. The morphological images showed amorphous multiwall nanotubes with s...
