  Advancement in nanoscience and biotechnology of bone materials and cement has been increasing over the past several decades. The combination of biomaterials with trace elements for bone cement has verified their better mechanical strength and biocompatibility response. Also, the ionic replacement has affected the chemical, physical and biological properties of the substance. Pyrophosphate has supported better absorption of calcium phosphates (CaPs) and bone formation. Bone cement is the ionomer of an important material in tooth repair application used in the tooth filling, tooth cover, and to fix adhesions of the tooth and crown. Nanoparticle additives (magnesium oxide (MgO), hydroxyapatite (HA), chitosan (CH), barium sulfate and silica) and alternate monomers can be effective with Polymethyl methacrylate (PMMA) granules and methyl methacrylate monomers (MMAs) to decrease the isothermal temperature. These materials can be used for the growth and development of bone cements. This paper aims to demonstrate a general and different view of the applications of CaP, PMMA, glass ionomer and bone repair cements in various methods under different experiments procedure. پرونده مقاله

  In this research, we develop and prepare some of the polymers based on polythioesters using cetrimide as an ionic liquid and phase transfer catalyst. All of the polymers were prepared through the reaction of 5,5'-methylenebis (1,3,4-oxadiazole-2-thiol) with five types of diacyl chloride derivatives in the presence of cetrimide as phase transfer catalyst in the mixture of water and chloroform at room temperature. The chemical structure of synthesized polymers was determined using 1H NMR and 13C NMR spectroscopy. The mechanical and thermal stability of the synthesized polymers were investigated. In addition, using DFT calculation, the chemical optimization of synthesized polymers was presented. Moreover, the catalytic activity of cetrimide was compared with four types of ionic liquid with phase transfer catalyst roles. Additionally, the application of synthesized polymers in bone cement was investigated. پرونده مقاله
