Abstract:
Equipping a slice of air film on a vehicle’s exterior can realize the goal of load reduction and attitude control in the vertical water-emerging process. Similar to ventilated cavity, the performance of this air film depends on the venting structures and their arrangements. Based on the simulation of vehicle’s water-emerging processes with exhaust, the effect of pitch-to-diameter ratio [Formula: see text] and row-spacing-to-diameter ratio [Formula: see text] of venting structures on evolution process of air film is investigated.

Abstract Atomic diffusion bonding (ADB) of wafers at room temperature in air was studied using Ag films. Using an ultra-high vacuum magnetron sputtering system, Ag (20 nm) films with Ti (5 nm) underlayers were deposited. The propagation speed of crystal lattice rearrangement in the bonding process decreased with an increased exposure time of film surfaces to air (t exp). Propagation did not occur at t exp of 500 s. The cohesion of Ag film surfaces by film surface exposure to air and reduction of the Ag film surface energy by Ag oxide or sulfide formation probably cause ADB performance degradat

Abstract Thin copper films with thickness ∼28 nm deposited on SiO2 substrate with the vacuum electron beam evaporation method and treated by UV-ozone are studied.

The formed oxide film effectively protects the copper against the following oxidation.

The indentation hardness of films was investigated by Force Volume Maps in both the air and liquid. In the air, ultrathin films are in the substrate-dominated zone and, thus, the elastic modulus E is overestimated, while E reaches its bulk value for drop-casted ultrathin and thick films. I

Indium tin oxide (ITO) films had been deposited on glass substrate without substrate heating and then tungsten oxide (WO3) films were deposited on ITO films by DC magnetron sputtering. In this work, we present the annealing ambient effect of ITO substrate on electrochromic properties of WO3 films. The ITO films were annealing in air and in vacuum at 350°C before coating with WO3 films. The structural, optical, and electrical properties of ITO films for as-deposited, annealing in air and in vacuum were investigated by X-ray diffraction, UV-VIS-NIR spectroscope and four point probe.

The lubricating air film between two rotating rollers in close contact was studied numerically. The numerical model used in this study accounts for the effects of air compressibility, material deformation, and the slip flow which occurs when the air film thickness is not much larger than the mean-free-path of the air molecules. The air film profiles and the pressure profiles for the nip region between the rollers were calculated. It was found that the calculated air film thicknesses are lower than predicted by the liquid elastohydrodynamic calculation. From this study, equations for the minimu

There has been much interest in developing scandium doped aluminum nitride (ScAlN) thin films for use in electronic devices, due to their excellent piezoMEMS response, large spontaneous polarization, and the capability for CMOS-compatible integration. As with the undoped AlN film, the formation of an oxide overlayer on the air-exposed ScAlN film can modulate its surface structure and the electrical properties. In this study, we investigate the effects of surface oxidation on a ScAlN film by characterizing the film microstructure and the elemental chemical states. We found that amorphous phase

The picture of the film surface structure obtained as a result of surface analysis shows a non-isotropic distribution of the metal and glass phase. For a firing peak temperature of 650℃ there is little nickel present at the film surface, and this could be the main cause of the high instability and low adhe

The X-ray reflectivity measurements additionally indicate that the film may be consistent with having a structure with increased electron density of film molecules towards the water, suggesting amphiphilic behaviour.

In this study, the mechanism of transfer brass film on steel substrate has been studied with the scanning electronic microscope, the optical microscope and the interferential microscope. The analysis shows that the transfer films properties (roughness, hardness, thickness) depend on the atmospheric conditions.

Since these films have thicknesses of several tens of nm, their material properties, including density, significantly deviate from the known bulk values.
