Over the past several decades, bioceramics have helped improve the quality of life for millions of people. These specially designed materials, which include polycrystalline aluminum oxide, HA (a calcium phosphate mineral that is also the major component of bones in vertebrates), partially stabilized zirconium oxide, bioactive glass or glass-ceramics, and polyethylene-HA composites, have been successfully used for the repair, reconstruction and replacement of diseased or damaged parts of the body, especially bone.

Graphene-oxide membranes have attracted considerable attention as promising candidates for new water treatment technologies. Graphene-oxide membranes have already demonstrated the potential of filtering out small nanoparticles, organic molecules, and even large salts. But, they couldn’t be used for sieving common salts used in desalination technologies, which require even smaller sieves.
The quantum cascade laser (QCL) market is attracting attention as a significant technology advance that engenders new innovations with noteworthy financial returns. What’s not to like?
