Regulation of the antibiotic elution profile from tricalcium phosphate bone cement by addition of bioactive glass.

This work aimed at tailoring of different properties of antibacterial drug delivery Ca-phosphate cements by incorporation of bioactive glass (BG). The cements were prepared from beta-tricalcium phosphate cement (β-TCP) and BG based on 50 SiO-20 CaO-15 NaO-7 BO-4 PO-4 AlO wt% with different percentages of BG [5, 10, 15, and 20% (w/w)]. The composite cements were characterized by XRD, FTIR, and TEM.

Enhancement of electrical conductivity associated with non-bridged oxygen defects in molybdenum phosphate oxide glass via doping of SrO.

Based on the attractive properties of phosphate glass, improved molybdenum phosphate glasses of composition 40PO, 20MoO, 15MgO, (25-x)LiO, xSrO, [x = 0, 5, 10, 15 and 20 mol %] were prepared via the melt-quench technique. They were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-visible reflectance and Electron spin resonance (ESR). FTIR confirmed the existence of several structural phosphate groups other than MoO and MoO units.

XRD, FTIR and ultrasonic investigations of cadmium lead bismuthate glasses.

Cadmium lead bismuthate glasses in the system xCdO-(1-x)[0.5PbO + 0.5BiO](40 mol% ≤ x ≤ 90 mol%) were successfully prepared by melt-quenching method.

Incorporation of strontium borosilicate bioactive glass in calcium aluminate biocement: Physicomechanical, bioactivity and antimicrobial properties.

Strontium borosilicate bioactive glass (SrBG) and calcium aluminate cement (CA) composites have been synthesized. The primary goal of this work is to evaluate how SrBG affects the bioactivity and physico-mechanical characteristics of CA. To fulfill this aim, SrBG was prepared by melt-quenching method and utilized as a substitute for CA by 5, 10, 15, and 20 wt%.

In vitro evaluation of some types of ferrimagnetic glass ceramics.

The present study aimed at studying the acceleration of the bioactive layer on the surface of ferrimagnetic glass ceramic with a basic composition 40Fe2O3-15P2O5-20SiO2-5TiO2 through the addition of 20% of different types of metal oxides like MgO or CaO or MnO or CuO or ZnO or CeO2. SEM, EDAX, and ICP were applied to present the results of the study. SEM and EDAX measurements indicated the presence of apatite layer formed on the surface of the prepared glass ceramics after immersion in SBF within 7 to 30 days.
