“…Many factors such as temperature, time, pH, catalytic agent for gel formation, and the environmental conditions can significantly affect the characteristics of the nanoparticles (Klabunde et al, 1996;Bokhimi et al, 1995). The advantages of the sol-gel method are simplicity, cost effectiveness, high yield of nanoparticles, and low reaction temperature (Jiu et al, 2003;Bokhimi et al, 1999;Subramania et al, 2007). Stengl et al (2004) described the preparation of magnesium hydroxide aerogels on the basis of the hydrolysis and condensation reactions of the alkoxide.…”

-Bacterial pollution is a great risk for human health. Nanotechnology offers a way to develop new inorganic antibacterial agents. Nano-inorganic metal oxide has a potential to reduce bacterial contamination. MgO is an important inorganic oxide and has been widely used in many fields. Many studies have shown that MgO nanoparticles have good antibacterial activity. Therefore, in this paper, the main synthesis methods, antibacterial activity and antibacterial mechanisms of MgO nanoparticles are reviewed.

On the Defect Origin of the Room‐Temperature Magnetism Universally Exhibited by Metal‐Oxide Nanoparticles

The occurrence of ferromagnetism in nanoparticles of otherwise non-magnetic oxides seems to be well established. It is, however, necessary to understand the origin of ferromagnetism in these materials. Herein, we present a combined study of the magnetic properties and photoluminescence (PL) behavior of nanoparticles of ZnO, ZrO(2), and MgO annealed at different temperatures (and therefore of different sizes). We find that the magnetization and the intensity of the bands due to defects vary parallel in all these materials. The adsorption of ethanol leads to a decrease in the magnetization and to a reduced intensity of the defect PL band of ZnO nanoparticles whereas UV irradiation has the opposite effect. We have also examined the effect of the morphology of the ZnO on the properties.

“…However, the useful properties of MgO are further enhanced when used as nano-size powder with novel nano structures. Many different synthetic routes provide nanoscale MgO including sol-gel [8], hydrothermal/solvothermal [9,10], laser vaporization [11], chemical gas phase deposition [12], aqueous wet chemical method [13], surfactant methods [14], polyol-mediated thermolysis process [15]. In the above mentioned methods, limitations such as requirement of sophisticated equipments, many processing steps, more time, template, surfactant, and energy dissipation in the preparation of MgO nanostructures were observed.…”
