Achieving the integration of friction reduction and wear resistance of moving parts is a complex
task in tribology. This paper proposes an ordered microporous nickel-based hard coating …

A filtering dielectric resonator (DR) antenna (DRA) that does not require any filtering circuits
is investigated. It deploys a rectangular DR and three slots fabricated in the ground plane. …

The potential tribological properties of load-adaptive M50-based self-lubricating composites
under various loads were investigated. Pure M50 and M50 composite containing 10 wt%(…
