background: dental cobalt base alloys are biocompatible dental materials and have been widely used in dentistry. however, metals are bioinert and may not present bioactivity in human body. bioactivity is the especial ability to interact with human body and make a bonding to soft and hard tissues. the aim of the present research was fabrication and bioactivity evaluation of novel cobalt alloy/ f...
Different aspects of biominerals formed by apatite and DNA have been investigated using computer modeling tools. Firstly, the structure and stability of biominerals in which DNA molecules are embedded into hydroxyapatite and fluoroapatite nanopores have been examined by combining different molecular mechanics methods. After this, the early processes in the nucleation of hydroxyapatite at a DNA ...
O materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents. Material and Methods: One hundred and twenty bar-shaped specimens were made from each of !" #" $%& !" # ' & and divided into 8 groups of 15 specimens each. Six groups were alternately immersed in the following storage agents for 30 min: deionized water (control), citrate buffer solution, pineapple juice, green mango juice, ...
The mesocrystal system fluoroapatite-gelatine grown by double-diffusion is characterized by hierarchical composite structure on a mesoscale. In the present work we apply solid state NMR to characterize its structure on the molecular level and provide a link between the structural organisation on the mesoscale and atomistic computer simulations. Thus, we find that the individual nanocrystals are...
