Graphite/metal alloy bearings handle harsh environments that lubricated bearings can’t. For example, a grease-filled ball bearing was used on an oven-door latch—but in tests, the bearing seized and ...

The inlet-air section of a utility boiler is a harsh environment for the dampers that control the flow of preheated air into the combustors. Over time, the hot air dries out the lubricant in the metal ...

In order to protect graphite, scientists are forming faceted metal islands of the rare-earth element dysprosium under layers of graphite by first adding defects and then depositing metal at elevated ...

Graphite-metal bearings can handle harsh environments that toast liquid-lubricated types. Agrease-filled ball bearing on an oven-door latch seizes and keeps the door from latching. It turns out the ...

"Rock-chair" Li-ion battery (LIB) was discovered in the late 1970s and commercialized in 1991 by Sony, which has become the priority way we store portable energy today. To honor the contribution for ...
