Antimicrobial and bioactive phosphate-free glass-ceramics for bone tissue engineering applications.

Glasses with composition 55SiO-10KO-(35-x)CaO-xMgO (x = 5, 10, 15 up to 35) were prepared via conventional melt-quench technique. The glasses were converted to glass-ceramics by controlled heat-treatment at 850 °C. Higher content of MgO instead of CaO prevents the devitrification of the glasses.

Agricultural wastes as a resource of raw materials for developing low-dielectric glass-ceramics.

Agricultural waste ashes are used as resource materials to synthesize new glass and glass-ceramics. The as-prepared materials are characterized using various techniques for their structural and dielectric properties to check their suitability in microelectronic applications. Sugarcane leaves ash exhibits higher content of alkali metal oxides than rice husk ash, which reduces the melting point of the components due to eutectic reactions.
