“…PVP, which contains polar pyrrolidinyl nitrogen and a carbonyl group was used as a suppressor in the Cu electrodeposition. 42 PVP can attract metal ions and form intermediate complexes due to the affinity of the functional groups. 43,44 The complexes physically inhibit the diffusion of metal ions to the electrical surface and suppress metal deposition.…”

Ru deposition in advanced technology nodes can improve performance by providing low resistance in nanoscale features. In this study, we reported the electrochemical reactions of Ru3+ on an Ru surface using multi-cyclic voltammetry (CV) and behavior of additives during Ru electrodeposition using linear sweep voltammetry (LSV) and potentiostatic measurements. Disodium 3,3'-dithiobis(1-propanesulfonate) (SPS), polyvinylpyrrolidone (PVP), and a bromide ion (Br-) were added for bottom-up filling. We investigated the suppression behavior of PVP. The current density and the onset potential of suppressor breakdown were affected by the suppressor concentration. PVP interacted synergistically with Br- and showed additional suppression. PVP formed a suppressing layer with Br- after formation of a bromide layer. SPS could reduce roughness during electrodeposition of Ru. Based on these results, nano-trenches were filled with Ru using the optimized additive condition.

“…Supercritical CO 2 (scCO 2 ) has seen widespread usage as a solvent in numerous industrial processes, notably in foaming, − creating porous materials, ,− extraction, , and manufacturing electronic devices. , This is largely due to its appealing properties, including moderate critical coordinates (with a critical temperature of T c = 304.12 K), reduced viscosity, and enhanced ability to permeate microstructures. The use of supercritical CO 2 for regenerating adsorbents leverages these qualities; its notable diffusivity aids in infiltrating the adsorbent’s pores, while its lower critical temperature and minimal interfacial tension help in preserving the pore framework of activated carbon. − As a result, employing supercritical CO 2 for regenerating activated carbon presents a practical alternative to the conventional thermal method.…”

The regeneration of spent activated carbon that captures alkyl acetate, a major volatile organic compound (VOC) in the printing field, is extremely important for economic and environmental implications. The use of supercritical CO 2 avoids the high heat associated with conventional thermal methods that can degrade the carbon. However, existing research on this is limited in scope, and more comprehensive studies are needed to fully understand the technology. In this study, a fixed-bed adsorption method was used to investigate the adsorption of hexyl acetate on activated carbon in supercritical CO 2 at T = (313−353) K and P = (10−20) MPa. The results are consistent with previous studies on similar VOCs and show the influence of temperature and pressure on adsorption equilibria. Hexyl acetate showed higher adsorption than propyl acetate and ethyl acetate, which may be due to its different volatility in supercritical CO 2 and its different affinity for the absorbent used. The analysis using the Dubinin−Astakhov (DA) equation offers a quantitative understanding of how supercritical CO 2 density and VOC molecular size influence adsorption equilibria. This insight is essential for developing an efficient and eco-friendly regeneration method for the printing industry utilizing supercritical CO 2 .

“…They found that Ni/TiO 2 composite materials prepared by SCNTO had better mechanical properties and showed no sample size effect. Sabarison Pandiyarajan et al [13] used two different electrodeposition methods, supercritical CO 2 (SC-CO 2 ) and ultrasonic-assisted supercritical CO 2 (US-SC-CO 2 ) electrodeposition, to improve the deposition quality of Cu-PVP composite coatings. They found that the electrodeposition quality and performance were improved under US-SC-CO 2 conditions.…”

A graphene quantum dots (GQDs)-reinforced nickel-based composite coating was electrodeposited on the surface of a copper plate with a supercritical carbon dioxide fluid (SC-CO2)-assisted DC power supply. The effect of the current density on surface morphology, microstructure, average grain size, hardness, and corrosion resistance of the resulting coatings was investigated in detail. It was found that the GQDs composite coating showed a more compact surface, a smaller grain size, higher microhardness, and stronger corrosion resistance than the pure Ni coating produced in SC-CO2 and a texture coefficient indicative of a (111) preferred orientation. When the current density was 8 A/dm2, the surface morphology of the GQDs composite coating showed a high density, and the grain size was about 23 nm. In addition, the micro-hardness and corrosion resistance of the GQDs composite coating was greatly improved compared with those of the pure nickel coating; at the same time, its wear rate, friction coefficient, and self-corrosion current density were decreased by 73.2%, 17.5%, and 9.2%, respectively.
