Archaeometry, EarlyView.Abstract Kohl was ubiquitous in ancient Egypt and the Middle East, and routinely included among the toiletries deposited in burials. For Egypt, kohl recipes are increasingly well‐studied and known to use a range of inorganic and organic ingredients. Although these are often lead‐based, manganese‐ and silicon‐rich compounds are also attested.

Medicine for the Material World
Archaeometry, EarlyView.ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Journal of Prosthodontics, EarlyView.Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

The term “powder metallurgy” covers the art of producing objects from metal powders, with or without the addition of non-metallic constituents. The powders may be pressed to a desired form in a suitable die and subsequently or simultaneously heated to produce a welded, alloyed, or coalesced mass.
