We investigate the drainage dynamics of thin liquid foam films containing PNiPAM microgel suspensions with two cross-linking densities (1.5 and 5 mol% BIS) and at two microgel concentrations (0.1 and 1% wt). For this purpose, we use a thin-film pressure balance apparatus that can apply a controlled and sudden hydrostatic pressure on a film, and record the subsequent film thinning as a function ...

Abstrac%. Satellites in the Jovian and temperature was measured by a cryodiode; the Saturnian system exhibit differences in measurement proved to be accurate to about 1 K by reflectivity between their "leading" and external calibration. With an electric heater in "trailing" surfaces which can affect the local the copper block, the cooled target could be vapor pressure. Since these differences a...

Bipolar resistive switching using organic molecule is very promising for memory application owing to their advantages like simple device structure, low manufacturing cost, stability and flexibility etc. Herein we report Langmuir-Blodgett spin-coated film based bipolar devices material indole derivative. Pressure - area per isotherm, Brewster Angle Microscopy, Atomic Force Microscopy Scanning El...

This article presents the use of a microstrip dual resonator for nondestructive permittivity characterization of a ferroelectric thin film at microwave frequencies. The dual-resonator measurement fixture consists mainly of two capacitively coupled microstrip resonators, with the ferroelectric thin film covering the gap between the two resonators. The dielectric constant and loss tangent of the ...

A unique bimetallic, nano platinum (Pt) with nano gold (Au) on nafion (NF) incorporated with functionalized multiwall carbon nanotubes (f-MWCNTs) composite film (f-MWCNTs-NF-PtAu) was developed by the potentiostatic method. The composite film exhibits promising efficient catalytic activity towards the oxidation of mixture of biochemical compounds and simultaneous measurement of ascorbate anion,...

..̂IJ Previous papers described the Phase IA tests of the Rocketdyne configuration of the Space Shuttle Main Engine (SSME) High Pressure Fuel Turbopump (HPFTP) turbine with rough coated flight engine rotor blades and with polished coated rotor blades at Marshall Space Flight Center (MSFC) . The testing involved using scaled performance parameters and model measurements to determine the performan...

This article evaluates the potential of capacitive measurements using flexible electrodes to access various physical quantities. These electrodes are made of a thin metallic film, typical thickness 0.2 microm, evaporated on a plastic substrate. Their large flexibility enables them to be mounted in complex geometries such as curved surfaces. In the configuration of planar condensers, using a ver...

We use a tunable diode laser operating near 1570 nm to investigate various effects of the heat transfer from fused-silica microspheres, with and without thin-film coatings, to the surrounding gas in a vacuum chamber. The resonance frequencies of microsphere whispering-gallery modes (WGMs), excited by a tapered-fiber coupler, shift with changing temperature (about -1.6 GHz/K at 1570 nm). This sh...

BACKGROUND Hydraulic dilatation is a novel method of cervical dilatation that is based on continuous controllable dilatation (CCBD) by the pumping of fluid into the balloon extension of the system. The main advantage of this procedure is that it allows control of and insight into the process of cervical dilatation. METHODS For the purposes of our research, we created a new and upgraded system...
