Hollow cathode apparatus [PDF]
, 1984 A hollow cathode apparatus is described, which can be rapidly and reliably started. An ignitor positioned upstream from the hollow cathode, generates a puff of plasma that flows with the primary gas to be ionized through the cathode.

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries
Advanced Functional Materials, EarlyView.Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Advanced Functional Materials, EarlyView.Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

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

The iron-neon hollow-cathode spectrum [PDF]
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1975 Over 4000 wave lengths are listed between 1900 and 9000 Å for Fe i, Fe ii, Ne i and Ne ii lines measured in a hollow cathode discharge tube with iron electrodes and a neon gas filling. Photoe-electric traces between 2400 and 5700 Å on a semiquantitative intensity scale are also included. For Fe i, energy values for 124 even and 240 odd levels have been
