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
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.

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.

Glass and glass-ceramic photonic systems
SPIE Proceedings, 2017The development of optically confined structure is a major topic in both basic and applied physics not solely ICT oriented but also concerning lighting, laser, sensing, energy, environment, biological and medical sciences, and quantum optics. Glasses and glass-ceramics activated by rare earth ions are the bricks of such structures.

The classic definition of glass is based on the historical method of formation: This is a very unusual way of defining any material. The result is that glass is now defined in several different ways.

Nature Chemistry, 2021
Among the tens of thousands of reported hybrid organic–inorganic crystals, only a small fraction of them are known to form a stable liquid upon heating. Now, a family of hybrid perovskites is shown to melt and, upon cooling, form glasses with a compelling combination of properties.

Vitreous materials, glazed stone and faience, were produced from about the 4th millennium BC and small glass objects from the late 3rd millennium BC but significant amounts of glass were not produced until around 1500 BC.

Current Opinion in Solid State and Materials Science, 1995
Amorphous metallic alloys, relative newcomers to the world of glasses, have properties that are unusual for solid metals. The metallic glasses, which exist in a very wide variety of compositions, combine fundamental interest with practical applications. They also serve as precursors for exciting new nanocrystalline materials.

Infrared transmitting glasses and glass-ceramics
Journal of Non-Crystalline Solids, 2006The demand for infrared materials which exhibit higher performance is still growing; both on the thermal and mechanical side as well as on the width of the optical window, with an extension of the transparency towards the long wavelength region to satisfy the requirements of space applications.
