nanomagnesium hydroxide (Mg (OH)2) is promising potential material for biomedical applications, such as nanomedicine. However, little is known about the hemolysis of nanostructured Mg (OH)2.In the present investigation, Mg (OH)2nanoparticles synthesized by precipitation technique using magnesium nitrate and sodium hydroxide. The phase structure and morphology of the Mg (OH)2nanoparticles are characterized by X-ray powder diffraction (XRD), selected area electronic diffraction (SAED) and transmission electron microscopy (TEM) respectively. Hemolytic activitiesin vitroare carried out on the synthesized nanoMg (OH)2samples and the studies reveal that Mg (OH)2nanoparticles have mild activity against erythrocytes.

In this paper, magnesium hydroxide (Mg(OH)2) nanoparticles with tunable morphologies have been selectively synthesized via a facile template-free solvothermal route. The as-synthesized samples were characterized by instrumental analyses such as transmission electron microscopy (TEM) and X-ray powder diffraction (XRD). It was found that the morphology and size of the final products strongly depended on the reaction temperature and duration time. By manipulating the temperature and time in the solvothermal treatment, fiber-like, sphere-like and garland-like magnesium hydroxide nanoparticles were obtained. The described method without any catalysts or templates for preparing magnesium hydroxide nanoparticles is promising for industrial production in competition with other approaches.

Nanocubes, monodispersed nanocrystals and nanospheres of Au have been prepared by a simple reaction between HAuCl4·4H2O, NaOH and NH2OH·HCl in the presence of gelatin. The role of gelatin and the affection of pH in producing the nanoparticles of Au were discussed. The products were characterized by X-ray powder diffraction, transmission electron microscopy, and UV-visible absorption spectroscopy. The sizes of the monodispersed nanocrystals of Au were estimated by Debye-Scherrer formula according to XRD spectrum.

Ag2Se nanocrystal was successfully prepared by ultrasonic synthesis in water and ethanol systems at an ambient pressure. The powder of selenium was used as the selenium ion source. The size of the nanocrystals is in the scope of 10-20nm. The products were characterized by some means including X-ray Powder Diffraction (XRD) and Transmission Electron Microscopy (TEM) which was used to study the thermostability of the product. The result of the experiments indicated that the concentration of the reactant, the pH of the solution, the react temperature and the surfactant had some important influence on the formation and the size of the Ag2Se nanoparticles. The method we reported here is proved to be a new and an easy way to prepare the nanocrystals of metal chalcogenide.

Using simple and efficient celloidin membrane as basic template, and adding polyglycol reagent as assistant template, the calcium carbonate assembly sphere chains were synthesized. The length of chains was 6-8 µm, and the building block spheres were formed by nanoparticles with about 50 nm in diameter. All the products were characterized by transmission electron microscopy, X-ray powder diffraction, thermogravimetry analysis. The decomposition temperature increased by about 30 °C compared with the separate spheres, which may be caused by the bonding power of the spheres in chains. The products of calcium carbonate chains that kept in alcohol for 90d were found to have second-assembly to novel flower-like structures.
