Surface-induced resistivity of thin metallic films bounded by a rough fractal surface
(2002)
We have extended the modified formalism of Sheng, Xing, and Wang [J. Phys.: Condens. Matter 11 L299 (1999)] to allow the calculation of the conductivity of a thin metallic film bounded by a rough fractal surface. We utilized ...
Faraday patterns in lubricated thin films
(2011)
We study the patterns observed in the vicinity of a Faraday instability, in the limit of a very
thin layer of viscous fluid. We numerically solve our previous model [N.O. Rojas et al., Phys. Rev. Lett.
104, 187801 (2010)] ...
Gradient theory of domain walls in thin, nematic liquid crystals films
(World Scientific Publishing, 2020)
In this paper, we describe domain walls appearing in a thin, nematic liquid crystal sample subject to an external field with intensity close to the Freedericksz transition threshold. Using the gradient theory of the phase ...
Positron annihilation studies on chemically synthesized FeCo alloy
(Nature Publishing, 2018-06-27)
Equiatomic flower-like FeCo magnetic nanoparticles are synthesized through a modified one-pot polyol technique. The as-prepared samples are annealed at 700 and 800 degrees C under reducing atmosphere. The saturation ...
A simple photochemical method to synthesize Ga2O 3Dy3M3 thin films and their evaluation as optical materials (where M=Cr or Co)
(2011)
We report the photochemical method to synthesize Ga2O 3Dy3Co3 and Ga2O3Dy 3Cr3 thin films. X-ray photoelectron spectroscopy, X-ray diffraction and photoluminescence were used to characterize the products. These analyses ...
Thin films of amphiphilic polyelectrolytes. Soft materials characterized by Kelvin probe force microscopy
(Elsevier, 2013)
Hydrophobically modified amphiphilic polyelectrolyte films derived from poly (maleic anhydride-altstyrene)
containing hydrophobic aryl-alkyl type side chains such as phenyl-ethyl, phenyl-butyl,
naphthyl-ethyl and ...
Harmonic solutions for polygonal hydraulic jumps in thin fluid films
(Cambridge Univ Press, 2015)
This article contains numerical and theoretical results on the circular and polygonal hydraulic jumps
in the framework of inertial lubrication theory. The free surface and velocity fields are computed
along with ...
Photocatalytic thin films containing TiO2:N nanopowders obtained by the layer-by-layer self-assembling method
(Elsevier, 2012)
In this work, TiO2–N powders were synthesized by high-energy ball milling, using commercial titanium
dioxide (TiO2) in the anatase phase and urea to introduce nitrogen into TiO2 in order to enhance their
photocatalytic ...
Electrodeposition of CdTe thin films onto n-Si(1 0 0): Nucleation and growth mechanisms
(2005)
The mechanisms related to the initial stages of the nucleation and growth of cadmium telluride (CdTe) thin films on the rough face side of a (1 0 0) monocrystalline n-type silicon have been studied as a function of different ...
Antibiofouling thin-film composite membranes (TFC) by in situ formation of Cu-(m-phenylenediamine) oligomer complex
(Springer, 2018)
In situ formation of a Cu-(m-phenylenediamine) (Cu-mPD) oligomer complex from copper chloride during the interfacial polymerization process was successfully employed to produce modified thin-film composite reverse osmosis ...
