Wetting and spreading behavior of liquid iron on single crystal TiO2 substrate

Publication date: 1 January 2020Source: Materials Letters, Volume 258Author(s): Changji Xuan, Keiji Nakajima, Hiroyuki Shibata, Pär Göran JönssonAbstractThis work reported the wetting and spreading behavior of pure iron droplet on single crystal TiO2 substrate. During the heating process, a “FeO·TiOx separated liquid phase” appeared at the temperature below the melting point of the pure iron, and completely covered the lower half of the iron droplet. The observed high-wetting behavior of the droplet is due to the spreading of the “separated liquid phase” rather than the iron droplet flow. According to both thermodynamic considerations and experimental measurements, the “separated liquid phase” is formed through the chemical interactions among the iron specimen, oxygen gas in the Ar atmosphere and TiO2 substrate.

The bottom-gate, bottom-contact geometry was selected for the graphene S/D contact r-SWCNT (Gr-SWCNT) transistor because of its enhanced gate modulation and good sustainability. A palladium S/D contact r-SWCNT...

Separation membranes bearing this adaptable wettability would be of great significance for practical applications because they can achieve on-demand oil/water separation according to the intrinsic properties of the targeting oil/water mixtures other than external stimuli. Herein, we report one novel type of such smart separation membranes by functionali...

It separates particles according to their wetting properties. In flotation pulp, particles and bubbles are highly dispersed in aqueous medium and in the presence of various flotation reagents. Almost all interfacial interactions including inter-particle, inter-bubble, and bubble-particle interact...

Abstract Herein, through a facile and energy-friendly approach, thermally stable manganese-derived amorphous stacked nanosheet (MASNS) coatings with controlled wetting property ranging from superhydrophilicity to superhydrophobicity were synthesized. The superhydrophobic MASNS coating exhibited remarkable selectivity and sensitivity in the solid phase microextraction (SPME) of non-polar aromatic analytes, even amid the abundance of polar compounds, due to the superhydrophobic effect and the stacked lamellar structures. The established method was applied to the determination of polycyclic aromatic hydrocarbons (PAH...
