Weak solutions to lubrication systems describing the evolution of bilayer thin films
نویسندگان
چکیده
The existence of global nonnegative weak solutions is proved for coupled one-dimensional lubrication systems that describe the evolution of nanoscopic bilayer thin polymer films that take account of Navier-slip or no-slip conditions at both liquid-liquid and liquidsolid interfaces. In addition, in the presence of attractive van der Waals and repulsive Born intermolecular interactions existence of positive smooth solutions is shown.

Weak solutions to lubrication equations in the presence of strong slippage
The existence of global weak solutions is proved for one-dimensional lubrication models that describe the dewetting process of nanoscopic thin polymer films on hydrophobyzed substrates and take account of large slippage at the polymer-substrate interface. The convergence of these solutions as either the Reynolds number or the capillarity goes to zero, as well as their limiting behaviour as the ...

Thin films of tin sulfide/cadmium sulfide (SnS/CdS) were prepared bythermal evaporation method at room temperature on a glass substrate and then annealedat different temperature with the aim of optimizing the optical properties of the materialfor use in photovoltaic solar cell devices. The effect of annealing on optical propertiesof SnS/CdS film was studied in the temper...
متن کاملThe Lubrication Approximation for Thin Viscous Films: the Moving Contact Line with a `porous Media' Cut off of Van Der Waals Interactions
We consider the effect of a second order ‘porous media’ [25] term on the evolution of weak solutions of the fourth order degenerate diffusion equation (1) ht = −∇ · (h∇∆h −∇h) in one space dimension. The equation without the second order term is derived from a ‘lubrication approximation’ and models surface tension dominated motion of thin viscous films and spreading droplets [18]. Here h(x, t) ...

Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...
متن کاملEffects of Localized Forcing on Driven Thin Liquid Films
Thin liquid films driven up an inclined plane by temperature-induced surface tension gradients have been the focus of extensive mathematical and experimental research. Using the lubrication approximation, the motion of a thin liquid film is described by a single fourth-order partial differential equation (PDE) that models the evolution of the height of the film. Such films are now known to exhi...
