Different physical properties of laser-damaged HfO2film on SiO2substrate were detected by scanning probe acoustic microscope. Surface topographies of SPM showed that the depth of laser-damaged hole on the HfO2film was close to the thickness of film, while the phase images in probe-vibration mode of SPAM showed that the hydrophilicity of damaged area of HfO2film was higher than undamaged area which led to stronger absorption to water vapor in air. Some scratches on SiO2substrate surface under HfO2film was found in the acoustic images in sample-vibration mode of SPAM.

We have developed a simple method of fabricating liquid metal nanowire (NW) arrays of eutectic GaIn (EGaIn). When an EGaIn droplet anchored on a flat substrate is pulled perpendicular to the substrate surface at room temperature, an hourglass shaped EGaIn is formed. At the neck of the shape, based on the Plateau–Rayleigh instability, the EGaIn bridge with periodically varying thicknesses is formed. Finally, the bridge is broken down by additional pulling. Then, EGaIn NW is formed at the surface of the breakpoint. In addition, EGaIn NW arrays are found to be fabricated by pulling multiple EGaIn droplets on a substrate simultaneously. The average diameter of the obtained NW was approximately 0.6 μm and the length of the NW depended on the amount of droplet anchored on the substrate. The EGaIn NWs fabricated in this study may be used for three-dimensional wiring for integrated circuits, the tips of scanning probe microscopes, and field electron emission arrays.

A numerical model for the simulation of slider vibrations in helium-air gas mixtures has been developed. The physical properties of the helium-air gas mixture, such as density, mean free path and viscosity, were determined to calculate the dynamic flying characteristics of a slider using the CMRR air bearing simulator. Frequency analysis shows that the helium percentage in the gas mixture can shift the second pitch mode of the slider to a higher frequency.

Abstract— This research aims to provide edible film made from fish bone gelatin of Pangasius catfish mixed breadfruit starch with different formulations. The study was carried out through three stages including breadfruit starch isolation, edible films fabrication and analysis of physical properties of resulted edible film such as thickness, water vapor transmission, tensile strength and percent of elongation as well as moisture content. Edible films which were formulated from fish bone gelatin of Pangasius catfish by breadfruit starch addition have thickness values ranged of ​​0.084-0.123 mm, 6.08 - 16.77% of moisture content, water vapor transmission of 1.07 - 1.60 g/ m²/hour, tensile strength of 0.245 - 1.186 MPa, and percent of elongation around 70 - 87.14%. The edible films from gelatin of Pangasius catfish bone with breadfruit starch addition have physical characteristic which fulfill the standard requirements issued by Japanese Industrial Standard (JIS) Keywords— edible film; biodegradable materials; fish gelatin;breadfruit starch; food packaging

Non Equilibrium

A class of non-equilibrium models for compressible multi-component uids is investigated. These models are subject to the choice of interfacial pressures and interfacial velocity as well as relaxation terms for velocity, pressure and chemical potentials. Sufficient conditions are derived for these quantities that ensure meaningful physical properties such as a non-negative entropy production and thermodynamical stability as well as mathematical properties such as hyperbolicity. For the relaxation of chemical potentials a three-component model gas-water-vapor is considered.

Previous work in our laboratory has demonstrated the use of scanning probe microscopy (SPM) techniques in the study of microstructure development in YBa2Cu3O7 (YBCO) thin films formed by pulsed-laser deposition (PLD) [e.g., Ref. 1]. Under certain deposition conditions a high density of surface outgrowths was observed. These outgrowths have been identified as a-axis-oriented YBCO grains nucleated at the substrate surface which grow in concert with the c-axis-oriented YBCO grains. This growth mechanism differs from that previously suggested for the formation of mixed a-axis-oriented/c-axis-oriented YBCO films. The microstructure of YBCO thin films deposited on vicinal substrates by PLD is very different from that observed for films grown on oriented substrates (even under equivalent deposition conditions). Films grown on vicinal LaA1O3 substrates consisted of elongated granular features oriented along common directions. The shape of these features is the result of step-flow growth where the ledges on the miscut substrates provide aligned and enhanced nucleation sites. Such features have been observed on films grown using several different deposition conditions: only the width of the features changed.
