OBJECTIVES According to importance and increasing application of nanoparticles and their toxicity, the identification effects of nanoparticles on physiological systems are essential. Some studies show magnesium has analgesic effect in some pain models but this evaluation was not carried on nano-magnesium oxide (MgO). Thus, present study was designed to evaluation effect of Mgo nanoparticles alo...

although the solubility of oxygen in molten aluminum alloys is said to be negligible, the fresh surface of the melt oxidizes quickly in the air and an oxide film is formed on the melt surface. oxide-metal-oxide sandwich technique is a method for the study of short-time surface oxide films. in this research, air was blown at 0.5 atmosphere into the melts of al-1mg and al-6mg alloys by means of a...

morphology of surface oxide film formed during pouring of molten magnesium alloy has been investigated. due to surface turbulence during casting, the oxide film necessarily makes folded cause in a dry surface to dry surface mode creating a double oxide film with the volume of air that can be encapsulated between folds of the film and this led to make gas bubbles or shrinkage cavities form. thes...

Controlling degradation of magnesium or its alloys in physiological saline solutions is essential for their potential applications in clinically viable implants. Rapid degradation of magnesium-based materials reduces the mechanical properties of implants prematurely and severely increases alkalinity of the local environment. Therefore, the objective of this study is to investigate the effects o...

background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

The synthesis of the nanopowders magnesium oxide and fluoride during operation a repetitive diffuse nanosecond discharge in argon at various pressures was performed. Nanosecond voltage pulses with an amplitude −70 kV, rise time 0.7 ns, duration ns were applied across point-to-plane gap 2 mm length. pulse repetition rate 60 Hz. high-voltage pointed electrode made magnesium. A cold plasma formed ...

We elucidated the distance-dependent plasmonic effects on radiative transitions from an Eu(3+) ion-doped phosphor by varying the thickness of the dielectric spacer. Magnesium oxide prepared by electron-beam evaporation was chosen for the dielectric spacer. Spectral overlap between emission from Eu(3+) ions and the plasmon band of Ag nanoparticles led to improved luminescence intensity. This lum...

Two-dimensional fluorescence difference spectroscopy (2-D FDS) was used to determine the unique spectral signatures of zinc oxide (ZnO), magnesium oxide (MgO), and 5% magnesium zinc oxide nanocomposite (5% Mg/ZnO) and was then used to demonstrate the change in spectral signature that occurs when physiologically important proteins, such as angiotensin-converting enzyme (ACE) and ribonuclease A (...

Dietary magnesium deficiency as well as excess sucrose has been shown to be associated with the generation of reactive oxygen species (ROS). Nitric oxide (NO) and induction of nitric oxide synthase (NOS) are two important markers of nitrosative stress. The present study was planned to investigate the effect of low magnesium diet on magnesium status and nitric oxide production in sucrose fed rat...
