Bioactive Glasses and Glass-Ceramics
2021The application of some special glass compositions to make implantable biomaterials has revolutionized the medical field and introduced the concept of “surface-active” or “bioactive” materials, which have the ability to elicit a specific biological response at the interface with the surrounding tissue.

The glass ceiling and the glass cliff are metaphors that point to discriminatory obstacles to the professional upward mobility of qualified women or other minorities, regardless of their actual performances. This entry defines these concepts, gives research illustrations of the phenomena and their causes, and points to real-life examples.

Bioactive glasses and glass-ceramics
Clinical Materials, 1993Bioactive materials are designed to induce a specific biological activity; in most cases the desired biological activity is one that will give strong bonding to bone. A range of materials has been assessed as being capable of bonding to bone, but this paper is solely concerned with bioactive glasses and glass-ceramics.

Research on oxynitride glasses has expanded considerably since the first systematic compositional investigations were begun some ten years ago. This review will briefly introduce that work with an emphasis on more recent developments. Also included is some discussion of the applications of oxynitride glasses in both bulk and thin film form.
