Key plasma processes in LaB6 thermionic hollow cathodes operating in He, D2, Ar, and Xe at 4–200 Pa and 0.25–5 A cm−2

AIP Advances
Key physical processes in a thermionic hollow cathode plasma are identified using an experimental dataset and a zero-dimensional model. Model predictions for voltage are in generally good agreement with the dataset when it is assumed that the plasma is ...

Toward Prostate Cancer Early Warning with a Self‐Powered Wearable Biosensing Platform Integrated with Machine Learning

Advanced Science, EarlyView.
ABSTRACT Current prostate cancer detection methods remain limited in non‐invasiveness and specificity, prompting interest in urinary biomarkers such as sarcosine. Here, we report a urine‐powered wearable platform for non‐invasive sarcosine detection as a proof‐of‐concept for decentralized early warning.

Insights Into CO2 Loss, pH Effects, and Tafel Kinetics in Ni Single Atom‐Driven Bicarbonate Electroreduction

Advanced Science, EarlyView.
Selective CO formation in bicarbonate electrolysis is achieved by retaining reactive CO2 and tuning pH, while the competing hydrogen evolution reaction occurs at the interface. The rate‐determining step couples the chemical equilibrium of bicarbonate/CO2 with electrochemical charge transfer, offering insight into optimizing reaction conditions for ...

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
