[ 1 ] - An Investigation on Milling Method in Reduction of Magnesium Nano-Powder Particles Based on Sustaining Chemical Activity

Magnesium has been used in aviation industries, automobile manufacturing, electronics and medical engineering due to its unique properties thus far. The main problem in its utilization is the high reactivity of magnesium with oxygen and humidity, which both changes its properties. The surface charge and different density results in difficulties in dispersion stability of the powder in an ...

[ 2 ] - Preparation and Characterization of High Specific Surface Area γ-Alumina Nanoparticles Via Sol-Gel Method

In the present investigation, γ-alumina nanoparticles with particle sizes less than 10 nm, high specific surface area (351 m2/g), high pore volumes and relatively narrow pore sizes distribution was prepared via sol-gel method in presence of aluminum isopropoxide as an aluminum precursor, distilled water, acetic acid as hydrolysis rate controller and tert-butanol as solvent. They had meso ...

[ 3 ] - In vitro evaluation of apatite/wollastonite glass–ceramic nano biocoatings on 316 alloys by plasma-sprayed

Among bioactive ceramics, the apatite/wollastonite (A/W) glass ceramic, containing apatite and wollastonite crystals in the glassy matrix, has been largely studied because of good bioactivity and used in some fields of medicine, especially in orthopedics and dentistry. However, medical applications of bioceramic are limited to non-load bearing applications because of their poor mechanical prope...

[ 4 ] - Titanium and Fluoride Co-substitution in Hydroxyl Apatite

Titanium and fluoride-containing hydroxyl apatite were synthesized through precipitation method following by a hydrothermal stage at 100oC for 6 hours. XRD analysis of the sample scalcinedat650oC for 1 hour revealed that all samples have pure apatite structure. The existence of Fluoride substitution in apatite structure was confirmed by FTIR(Fourier Transform Infrared Spectroscopy) analysis. Su...
