Astrophysicists are starting to treat a strange class of “undead” suns as potential tools rather than mere curiosities, ...

A strange double flash in a distant galaxy has given astronomers their strongest hint yet that a long‑theorized kind of ...

Abstract: In robot joints or rotary vector (RV) reducers, where cycloidal gears perform complex low-speed rotating motions involving reciprocating variable speed and incomplete rotation, conventional ...

Effective training helps workers understand gas hazards, respond to alarms, and reduce exposure to toxic, flammable, and oxygen-deficient atmospheres.

Abstract: 2-D materials are promising candidates for gas sensing applications due to their high surface to volume ratio. However, graphene and MoS2, two prominent members of these materials, show ...
