We use a newly developed set of boundary conditions to revisit the problem of an evaporating thin liquid film. In particular, instead of the conventional Hertz–Knudsen– Langmuir equation for the evaporation mass flux we impose a more general equation expressing the balance of configurational momentum. This balance, which supplements the conventional conditions enforcing the balances of mass, mo...

Film boiling on a horizontal elliptical tube immersed in external flowing nitrogen liquid is investigated in the present paper. The isothermal wall temperature is high enough to induce turbulent film boiling, and then a continuous vapor film runs upward over the surface. The high velocity of the flowing saturated liquid at the boundary layer is determined by potential flow theory. In addition, ...

In this work we present an experimental study of deviations from the classical Landau-Levich law in the problem of dip coating. Among the examined causes leading to deviations are the nature of the liquid-gas and liquid-solid interfaces. The thickness of the coating film created by withdrawal of a plate from a bath was measured gravimetrically over a wide range of capillary numbers for both smo...

BACKGROUND Dysregulated iron metabolism has been suspected to be linked to anemia of chronic disease and to cardiovascular disease (CVD). For the purpose of clarifying the factors affecting arterial stiffness, we evaluated the relationship between iron metabolism, brachial-ankle (ba)-pulse wave velocity (PWV) and several risk factors for CVD in maintenance hemodialysis (MHD) patients. METHODS...

The global thin film transistor-liquid crystal display (TFT-LCD) manufacturers concentrate in Korea, Japan and Taiwan. In view of growing rapidly of demand in the world, the competition of TFT-LCD manufacturers has been a fierce phenomenon. The most important subject for every TFT-LCD manufacturer administrator is how to make the best disposition of resources and create more and more profits. T...

The structure and the orientation of thermotropic hexagonal columnar liquid crystals are studied by grazing incidence X-ray diffraction (GIXD) for different discotic compounds in the geometry of open supported thin films. Whatever the film deposition mode (either spin-coating or vacuum evaporation) and the film thickness, a degenerate planar alignment with the liquid crystalline columns paralle...

The hydrate/methane gas interface is studied by molecular dynamics simulations. Below the hydrate melting temperature a thin liquid film forms with an associated surface charge density and electrostatic potential. The thickness of the thin liquid film, the charge density, and electrostatic potential at the hydrate/gas interface are established at different subcooling temperatures for the first ...

We study the behavior of a mixed Langmuir monolayer consisting of a fatty acid and a nematic liquid crystal. We demonstrate that the mixed monolayer successfully transfers as a Langmuir-Blodgett film and characterize the transferred film using UV spectroscopy. An important application of Langmuir-Blodgett films is in the alignment of liquid crystals for electro-optical applications, such as dis...

Molecular dynamics simulations have been employed to investigate the boiling phenomena of thin liquid films adsorbed on a nanostructured solid surface. The molecular system was comprised of the following: solid platinum wall, liquid argon, and argon vapor. A few layers of the liquid argon were placed on the nanoposts decorated solid surface. The nanoposts height was varied keeping the liquid fi...

The TFT LCD (Thin Film Transistor Liquid Crystal Display) industry is one the most rapid growth high-technology industry in recent decades. The development process of this industry is complex and dynamic, requires the accumulation of technology capability, capital, production capacity, and human resources. For a late coming country, the development process also involves with tense interactions ...
