Positive Heavy-Ion Sources [PDF]
, 1985 Ion sources were developed soon after the discovery of ions in gas discharges in the late 1800s (Va 77). The initial uses were for mass spectrometry and for nuclear physics accelerators. In recent years, more versatile accelerator sources have been required to meet the need for a broad range of ion species, intensities, and duty factors and to fit the ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

GNSS Receiver Testing Focusing on Strong Interference by Use of a Hardware Signal Simulator
, 2008 In aviation environments various interference sources exist, which can degrade the performance of on-board receivers as well as the performance of ground based reference receivers (e.g. in GBAS stations). Therefore, besides functional receiver validation

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Electric potential and ion drag force in highly collisional complex plasma [PDF]
, 2008 This PhD thesis is a cumulative dissertation that consists of three papers. The first paper describes the qualitative as well as quantitative nature of the electrostatic potential behind a macroparticle in a drifting collisional plasma and also the ion

Advanced Engineering Materials, EarlyView.This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...
