“…However, these studies presented the processes involving CO 2 absorption assisted by a magnetic field instead of CO 2 adsorption assisted by a magnetic field. Recently, the effect of magnetowater wetting on CO 2 adsorption has been studied theoretically by Wu et al [37]. This study replicated the phenomena of water-cluster fragmentation and hydrogen bond creation, which was reported by molecular dynamic simulation from 0 to 10 T, enabling a quantitative study of the magneto-wetting process.…”

“…As a result, the popular belief that the magneto-water-wetting effect increases the CO 2 collection efficiency of diverse nanofluids is incorrect. The control mechanism of magnetic radiation is the formation of an H2O film on the surface of pores due to the magneto-wetting [37]. This H2O film hinders the diffusion of vapor-H2O into the lattice and slows the hydration of the powder during the aging process.…”

“…Therefore, due to these arrangements, more H2O molecules tend to adsorb into sample under the MF, resulting in H2O molecules blocking the pores and leading to the relative decrease in CO2 adsorption in comparison with the aged samples without MF. This can also promote the formation of carbonates in the The control mechanism of magnetic radiation is the formation of an H 2 O film on the surface of pores due to the magneto-wetting [37].

MgO/Mg(OH)2-based materials have been intensively explored for CO2 adsorption due to their high theoretical but low practical CO2 capture efficiency. Our previous study on the effect of H2O wetting on CO2 adsorption in MgO/Mg(OH)2 nanostructures found that the presence of H2O molecules significantly increases (decreases) CO2 adsorption on the MgO (Mg(OH)2) surface. Furthermore, the magneto-water-wetting technique is used to improve the CO2 capture efficiency of various nanofluids by increasing the mass transfer efficiency of nanobeads. However, the influence of magneto-wetting to the CO2 adsorption at nanobead surfaces remains unknown. The effect of magneto-water-wetting on CO2 adsorption on MgO/Mg(OH)2 nanocomposites was investigated experimentally in this study. Contrary to popular belief, magneto-water-wetting does not always increase CO2 adsorption; in fact, if Mg(OH)2 dominates in the nanocomposite, it can actually decrease CO2 adsorption. As a result of our structural research, we hypothesized that the creation of a thin H2O layer between nanograins prevents CO2 from flowing through, hence slowing down CO2 adsorption during the carbon-hydration aging process. Finally, the magneto-water-wetting technique can be used to control the carbon-hydration process and uncover both novel insights and discoveries of CO2 capture from air at room temperature to guide the design and development of ferrofluid devices for biomedical and energy applications.

In this study, Al−Mg and Al−Mg−Sc ER5356 welding wires were adopted, and the effects of the Sc element on the wetting behavior of the molten metal and the porosity of the deposited metal were investigated. Al−Mg−Sc and Al−Mg welding wires exhibit wetting angles of 17.2 and 12.4°, respectively, and their porosities of deposited metal were 0.885 and 0.454%, respectively. Adding the Sc element to ER5356 welding wires reduced the surface tension and then increased the pore difference pressure, wettability, and spreadability of the molten pool, which is beneficial for pore overflow. Besides, adding Sc elements could increase the molten droplet size and the metallic vapor recoil for the ER5356 wire and then stabilize droplet transfer.

“…Notably, the knowledge on this will undoubtedly help in understanding the role of interfacial properties during the dewetting of a magnetic volume, which is relevant to several applications, including the formation of emergent structures from magnetic fluids. 66 In this regard, theoretical advancements, such as exploring the contact angle change from the entropic perspective during magnetowettingm 214 can also provide substantial information. Furthermore, the response of an FF droplet system in the presence of a variety of magnetic systems 215 (e.g., integrated micro-magnetic systems, hybrid magnetic systems, circularly polarized magnetic fields, conically polarized magnetic fields, etc.)…”
