We investigate the equilibrium of a fluid in contact with a solid boundary through a density-functional theory. Depending on the conditions, the fluid can be in one phase, gas or liquid, or two phases, while the wall induces an external field acting on the fluid particles. We first examine the case of a liquid film in contact with the wall. We construct bifurcation diagrams for the film thickne...

The aim of the present work was to evaluate the effects of 2 different packaging films on chemical, physical, and microbiological variables in veal calf meat. Slices from the right half carcass were sampled from each calf: 8 were packaged with Cryovac film (25 μm thick) and 8 were packaged with Weegal film (45 μm thick). In both packaging types, the same gas mixture was used. The samples were a...

This work reports the preparation of a three-dimensional Si thin film negative electrode employing a porous Cu current collector. A previously reported copper etching procedure was modified to develop the porous structures inside a 9 μm thick copper foil. Magnetron sputtering was used for the deposition of an n-type doped 400 nm thick amorphous Si thin film. Electrochemical cycling of the prepa...

In this work, a planar solid-state potentiometric CO2 sensor for medical applications of the type CO2, O2, Au, Li2CO3-BaCO3 | Nasicon | Na2Ti6O13-TiO2, Au, O2, CO2 was developed in thick-film technology. Due to an integrated screen-printed platinum heater on the rear side, the sensor can be applied without changing its working temperature of 525°C in the main flow of the respiratory air of an i...

A high contrast electroluminescent (EL) device structure is presented. The diffuse luminous reflectivity from the metal/dielectric/phosphor/indium-tin-oxide/glass EL device structure is 3%. A Eu-doped GaN phosphor is used to demonstrate the contrast-enhanced operation. Low reflectivity is achieved by inserting a light-absorbing black thick-film BaTiO3 layer between the phosphor and the rear met...

In a group of 596 delivering Ghanaian women, the sensitivities of peripheral blood thick film microscopy, ICT Malaria P.f/P.v test, and PCR in detecting microscopically confirmed placental Plasmodium falciparum infection were 42, 80, and 97%, respectively. In addition to the gross underestimation of placental malaria by peripheral blood film microscopy, submicroscopic infections were found to b...

The preparation of La0.4Sr0.6TiO3 (LSTO) buffer layer and YBa2Cu3O7−δ (YBCO) superconducting thick film by a low cost technology was studied. The crystal orientation of LSTO and YBCO films was detected by X-ray diffraction, the conductivity of LSTO film and superconductivity of YBCO coating were investigated by standard four-probe method. Excellent in-plane alignment, smooth and dense LSTO buff...

Two problems of technological importance for microelectromechanical systems ~MEMS! and microelectronics industry are addressed: fatigue of thin films and nanoscale film cracking. A device is described that can ~1! conduct biaxial fatigue tests on thin films and ~2! be utilized to study fracture patterns in nanoscale coatings under biaxial stress state. Thin-film specimens, in the form of circul...

We have measured the vibrational Raman spectrum of a 1.2-microm-thick polystyrene film by using this film as an optical waveguide in a waveguide-stimulated Raman gain experiment. A gain factor of 1.3% was measured for the strong benzene mode at 1002 cm(-1). This value is in reasonable agreement with theoretical predictions.
