“…The value of J is sensitive to the work function, which depends on the type of ions interacted on the steel bar's surface [31], the crystal structure of the metal surface [32], or more. J calculated varies between 5 × 10 −4 to 3.83 × 10 −2 mA cm −2 (for W = 4.34 and 4.7, respectively) or 2.48 × 10 12 to1.55 × 10 14 electrons cm −2 .…”

Plasma contacting with liquid provides many charged particles and reactive species into the liquid. The diﬃculty in controlling or selecting each speciﬁc species has signiﬁcantly limited its applications in industry. Here, we present a study on using voltage polarity to regulate the type of charged particles absorbing from plasma into liquid. Detailed understanding of the processes at the plasma-liquid interface, electrolysis due to switching in voltage polarity was investigated via a visual pH observation, measuring the concentration of H2O2 and solvated electrons. The results indicated that changing in voltage polarity strongly aﬀects the plasma properties, chemical properties, and electrolysis process in liquid, and further in the types of reducing species for gold nanoparticle synthesis. The results also showed using a suitable frequency could improve the eﬃciency of absorption of H2O2from plasma into the bulk liquid and the yield in the production of gold nanoparticles. The results provide a way to select desired species from plasma into the liquid for a distinct purpose and accompanying other properties in the system of plasma contacting with liquid.

“…Various surface treatments, including ion implantation, were examined to improve the properties of AISI 321 steel. In [10], the effect of Ar + and H + ions irradiation on the electron work function was investigated. It was found that argon ions implantation results in a decrease in the electron work function, whereas irradiation by hydrogen ion results in an increase in this value.…”

Commercial rolled AISI 321 stainless steel samples were irradiated with Al+ ions with an energy of 80 keV and fluence of 1017 ion/cm2. The effect of Al implantation on the chemical and phase composition of the steel surface layer was studied by X-ray electron spectroscopy and grazing beam mode of X-ray diffraction analysis. A thin surface layer down to a depth of 30 nm after Al+ ions implantation consists mainly of metal oxides. In the near-surface layers of 5 nm in depth, a noticeable depletion in chromium and nickel was observed. A surface layer (up to 0.5 µm) of non-irradiated steel, in addition to the f.c.c. austenite γ-phase, consists of up to 20 vol% of the b.c.c. α′-phase, which formed at rolling as a result of mechanical deformation. Al implantation results in the significant increase in the α′-phase amount in the surface layer at a depth up to 2 µm. It is indicated that the observed γ → α′ transformation at ion irradiation proceeds predominantly as a result of the effect of post-cascade shock waves, but not as a result of the surface layer chemical composition changes.
