Properties of stainless-steel surface after hollow cathode assisted plasma nitriding
AISI 304 stainless steel was nitrided at different temperature in the plasma equipment using a new auxiliary device. The proposed hollow cathode auxiliary device improves the plasma density, thereby accelerating the nitriding process.

RF Plasma Nitriding of Titanium.
RF plasma nitriding of titanium was carried out at different temperatures and electric potentials of the samples, at 1.0-1.3 Torr in mixtures of nitrogen and hydrogen gases. The addition of hydrogen to nitrogen increased the nitriding rate and the hardness of the nitrogen diffusion layer.

Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.
