Bioactive glass formed on the base sample (Go) of 45S5 system with fluorine additives samples were prepared by melt quenching method. The glassy samples were subjected to DTA for determining temperatures at which phase transition occur. FTTR spectroscopy shed a light on the sorts of compounds, their structure as well as their functional groups. The crystalline nature of samples was confirmed by...

nerve regeneration. T main body of research involving bioactive glasses (BGs) has been devoted to applications in orthopedics and dentistry, given that the original composition 45S5 BioglassTM was developed to treat non-self-healing bone defects, such as bullet trauma or cancer. Because of their high bioactivity, BGs directly bond to bone. That bioactivity recently has been appreciated to exten...

Bioglass® 45S5 is widely used in biomedical applications due to its ability to bond to bone and even to soft tissues. The sintering ability of Bioglass powders is a key factor from a technological point of view, since its govern the production of advanced devices, ranging from highly porous scaffolds to functionalized coatings. Unfortunately this particular glass composition is prone to crystal...

The bioactive glass 45S5 was crystallized to 8-100 vol % of crystals by thermal treatments from 550-680 degrees C. The micro-structure of the glass-ceramics had a very uniform crystal size, ranging from 8 to 20 microns. Fourier-transform infrared (FTIR) spectroscopy was used to determine the rate of hydroxycarbonate apatite (HCA) formation that occurs on bioactive glass and glass-ceramic implan...

Particulate 45S5 Bioglass with an average size of 46 microm was incorporated into a high density polyethylene (HDPE) for potential medical applications. Composites with Bioglass volumes of 10, 20, and 40% were produced by a manufacturing process consisting of blending, compounding, powdering, and compression molding. The Bioglass particles were well dispersed, and their homogeneous distribution...

The interfacial characteristics between bioactive glass (45S5 Bioglass) surfaces and poly(α-hydroxyacid) melts have been assessed by direct wetting measurements. In particular, the wettability of Bioglass powder by poly(D,Llactide) (PDLLA) and poly(D,L-lactide-co-glycolide) (PLGA) was assessed by imbibition measurements. Additionally, the equilibrium contact angles of PDLLA and PLGA melts on a ...
