Thin Film Interference of Colloidal Thin Films

Langmuir, 2004
A stairlike colloidal crystal thin film composed of poly(styrene-methyl methacrylate-acrylic acid) (P(St-MMA-AA)) monodispersed colloids was fabricated on an inclined silicon substrate. Different bright colors were observed on the various parts of the film with different layers as white light irradiated perpendicularly on it.

Brittle Thin Films

Applied Mathematics & Optimization, 2001
In this paper a two-dimensional model for brittle thin films is obtained from a three-dimensional fracture model for elastic material. Using methods of \(\Gamma\)-convergence with adaptations to the spaces of special functions of bounded variation and to the thin films framework the authors find the limit effective energy as the thickness of the ...

Thin-Film Microextraction

Analytical Chemistry, 2003
The properties of a thin sheet of poly(dimethylsiloxane) (PDMS) membrane as an extraction phase were examined and compared to solid-phase microextraction (SPME) PDMS-coated fiber for application to semivolatile analytes in direct and headspace modes.

Thin Ferromagnetic Films

Physical Review, 1951
The magnetic properties of thin films of ferromagnetic materials have been studied by means of the Bloch spin-wave theory. The spontaneous magnetization depends upon the number of atomic layers, ${G}_{z}$, in the film. For thicknesses below a "critical" thickness, which depends on the temperature and film dimensions, the spontaneous magnetization ...
