Properties of stainless-steel surface after hollow cathode assisted plasma nitriding

open access: yesMaterials Research Express, 2020
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.

Tailoring the Hollow Structure within CoSn(OH)6 Nanocubes for Advanced Supercapacitors

open access: yesMolecules, 2022
The enhanced application performance of hollow-structured materials is attributed to their large surface area with more active sites. In this work, the hollow CoSn(OH)6 nanocubes with increased surface area and mesopores were derived from dense CoSn(OH)6

Note: Coaxial-heater hollow cathode

open access: yesReview of Scientific Instruments, 2017
The design and tests of a LaB6 hollow cathode with a novel heater are presented. In the new design, the heater wire is completely encapsulated around the cathode tube and a coaxial return electrode, thereby eliminating hot spots on the heater wire due to the free hanging regions. Since the new heater confines the Joule heating to the region of interest,
