PID control is the gold standard for most moving machines, and quite adequate in most applications that require closed-loop control. However, it's vulnerable to disturbances, and tuning can be tedious ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

The Series BNS-B20 safety-door handle system is designed for use as a combination door handle and safety interlock switch on light to medium-weight hinged and sliding machine guards. The ...

Iowa State scientist develops lab machine to study glacial sliding related to rising sea levels AMES, Iowa - Neal Iverson opened his laboratory's walk-in freezer and said the one-of-a-kind machine ...

The complex of ammonium-linked ferrocene (Fc-amm) and crown ether is assembled on a Cu(111) surface, and its sliding motion is activated by hole injection into the ferrocene group using scanning ...
