Q -anisotropy in finely-layered media
(American Geophysical Union, 2010-03)
Finely-layered media behaves as a transversely isotropic medium at long wavelengths. If the constituent media are anelastic, Q-anisotropy is described by Postma averaging for two periodic layers and by Backus averaging for ...
Structural and physicochemical aspects of drug release from layered double hydroxides and layered hydroxide salts
(Elsevier Science, 2015-03)
Layered double hydroxides (LDHs) and Zn layered hydroxide salts (LHSs) present different physicochemical and interfacial properties derived from their dissimilar structure and composition, which affect the release behavior ...
First-order doubly-asymptotic formulation of the direct stiffness method for elastodynamic problems
(Elsevier, 2014-11)
A first-order formulation to analyze the dynamic response of layered soil profiles is presented as an alternative to the widely used second-order thin-layer method by the direct stiffness approach, including an efficient ...
Reflection and transmission coefficients of a single layer in poroelastic media
(Acoustical Society of America Institute of Physics, 2014-03)
Wave propagation in poroelastic media is a subject that finds applications in many fields of research, from geophysics of the solid Earth to material science. In geophysics, seismic methods are based on the reflection and ...
Layer‐by‐Layer Formation of Polyamine‐Salt Aggregate/Polyelectrolyte Multilayers. Loading and Controlled Release of Probe Molecules from Self‐Assembled Supramolecular Networks
(Wiley VCH Verlag, 2019-06)
The use of soft materials as building blocks in layer-by-layer (LbL) assemblies represent a very appealing and useful approach to enhance the loading capacity of thin films. Here, the capacity of positively charged ...
Retrieval of the optical properties of a semiinfinite compartment in a layered scattering medium by single-distance, time-resolved diffuse reflectance measurements
(Pergamon-Elsevier Science Ltd, 2017-03)
Functional analysis of the human brain requires methods that take the layered structure of the head into account. In this work we introduce an improved theoretical model that describes light propagation in multilayered, ...
Layer-by-Layer assembled cobalt ferrite nanoparticles for chemical sensing
(American Scientific Publishers - ASPValencia, 2013-09)
Ultra-thin (thicknesses of 50-90 nm) nanocomposite films of cobalt ferrite nanoparticles (np-CoFe2O4, 18 nm in diameter) and polyelectrolytes (doped polyaniline-PANI, poly-3,4-ethylenedioxy thiophene: polystyrene sulfonic ...
Capillary pressure-saturation curves of thin hydrophilic fibrous layers: effects of overburden pressure, number of layers, and multiple imbibition-drainage cycles
(Sage Publications Ltd, 2019-12-01)
Unsaturated fluid flow in thin porous media depends on hydraulic properties, such as the capillary pressure, P-c, as a function of saturation, S. We measured this relationship for two different types of compressible thin ...
