Diopside-magnetite; A novel nanocomposite for hyperthermia applications.

In the present work, the releasing heat, scaffold apatite formation, and magnetic behavior of a novel diopside-magnetite nanocomposite with various contents of magnetite (FeO) were evaluated. The N´eel and Brown relaxations did not have a significant effect on the specific absorption rate (SAR) of the composite samples. Indeed, magnetic saturation, M, indicated a crucial effect on the heat release of the samples.

Preparing diopside nanoparticle scaffolds via space holder method: Simulation of the compressive strength and porosity.

In the present study, diopside nanopowders were prepared via mechanical milling with eggshell as the calcium source. The space holder method (compaction of ceramic powder and spacer) as one of the most important methods to produce ceramic/metal scaffolds was used to produce diopside scaffolds. For the first time, the effect of the spacer size on mechanical properties and porosity of the obtained scaffolds was experimentally discussed.

On the synthesis of nanostructured akermanite scaffolds via space holder method: The effect of the spacer size on the porosity and mechanical properties.

In the present study, for the first time, the space holder method was used to prepare akermanite scaffolds with high porous structures, high interconnectivity, and high compressive strength, while the role of different spacer sizes on the akermanite scaffold properties was also evaluated. The results showed that the increase in the NaCl particle size which was used as spacer leads to an increase of the pore size and interconnectivity and a decrease of compressive strength. When the size of the spacer was 420-600µm and more than 600µm, a total porosity of 82 and 83% and a compressive strength of 0.

A comparative study on the synthesis mechanism, bioactivity and mechanical properties of three silicate bioceramics.

In the present study three akermanite (CaMgSiO), diopside (CaMgSiO) and baghdadite (CaZrSiO) applicable bioceramics were synthesized via a sol-gel based method. The combination of sol-gel method and the raw materials used in this study presents a new route for the synthesis of the mentioned bioceramics. By the use of thermal analysis, the mechanisms occurred during the synthesis of these bioceramics were investigated.

Study of in vitro bioactivity and mechanical properties of diopside nano-bioceramic synthesized by a facile method using eggshell as raw material.

In this study, diopside bioceramic was synthesized using a mechanical milling process and subsequent heat treatment. The simplicity of experiments and also the high energy available in ball milling lead to rapid synthesis of the products in comparison with other synthesis methods. Magnesium oxide (MgO), silicon dioxide (SiO) and eggshell (as the calcium source) powders were weighted in stoichiometric conditions and milled to initial activation of the surface of the powder's mixture.

A novel and economical route for synthesizing akermanite (CaMgSiO) nano-bioceramic.

Despite the benefits of akermanite, there are limited reports on making powder and dense bulk akermanite (CaMgSiO) and most articles have focused on building akermanite scaffolds. This study centers on a new and economical route for the synthesis of akermanite bioceramic via high energy ball milling and subsequent sintering of a mixed powders of eggshell (as calcium source), MgO, and SiO. The mechanisms occurred during akermanite synthesis were carefully investigated.
