High- and low-energy x-ray photoelectron techniques for compositional depth profiles: destructive versus non-destructive methods
(IOP Science, 2013-01-17)
Hard x-ray photoelectron spectroscopy (HAXPES), angle-resolved x-ray photoelectron spectroscopy (ARXPS) and x-ray photoelectron spectroscopy (XPS) with simultaneous Ar+ bombardment are used to obtain chemical information ...

Facies analysis, foraminiferal record and chronostratigraphy of Holocene sequences from Saltés Island (Tinto-Odiel estuary, SW Spain): The origin of high-energy deposits
(Elsevier, 2019)
A multidisciplinary analysis of Holocene sediments from La Cascajera (Tinto-Odiel estuary, SW Spain) has al lowed to differentiate five sedimentary facies (sandy tidal flat, clayey tidal flat, washover fan, salt marsh, edaphic ...

U-series dating of speleothems from the Sierra del Endrinal (Grazalema Mountains, S Spain)
(Elsevier, 2012)
The uranium-series method is applied to date relic flowstone from karstic mountains in the south of Spain. Geomorphological mapping shows three staircased erosion surfaces with a typical karst landform. Exhumed flowstones fill ...

Phosphogypsum amendments and irrigation with acidulated water affect tomato nutrition in reclaimed marsh soils from SW Spain
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2014)
Phosphogypsum (PG) is a by-product of the P fertilizer industry usually valorised as amendment for acidic and sodic soils. This work was aimed to study the effects of PG on nutrient uptake by industrial tomato plants in ...

Comprehensive environmental testing of optical properties in thin films
(ScienceDirect, 2014)
Environmental characterization of optical and structural properties of thin films continues to be a challenging task. To understand the failure mechanism in high temperature thin film applications, it is crucial to ...

An energy-based stability criterion for solitary traveling waves in Hamiltonian lattices
(The Royal Society, 2017)
In this work, we revisit a criterion, originally proposed in [Nonlinearity 17, 207 (2004)], for the stability of solitary traveling waves in Hamiltonian, infinite-dimensional lattice dynamical systems. We discuss the ...

Solitary waves in the nonlinear Dirac equation in the presence of external driving forces
(IOP, 2016)
We consider the nonlinear Dirac (NLD) equation in 1+1 dimension with scalar-scalar selfinteraction in the presence of external forces as well as damping of the form f (x, t) - ιμγͦψ, where both f and ψ are two-component ...

Stoichiometric Control of SiOx Thin Films Grown by Reactive Magnetron Sputtering at Oblique Angles
(Wiley, 2016)
The deposition of SiOx (x < 2) compound thin films by the reactive magnetron sputtering technique at oblique angles is studied from both theoretical and experimental points of view. A simple mathematical formula that links ...

Evolution of the crystalline structure in (Bi0.5Na0.5)1-xBa x TiO3 thin films around the Morphotropic Phase Boundary
(Elsevier, 2014)
(Bi0.5Na0.5)1-xBax TiO3 (BNBT), which exhibits compositions for the morphotropic phase boundary (MPB) where exist an intimate coexistence of the rhombohedral and tetragonal structures, is being considered as promising ...

First spectral emissivity study of a solar selective coating in the 150–600 1C temperature range
(ScienceDirect, 2013-10)
A complete experimental study of temperature dependence of the total spectral emissivity has been performed, for the first time, for absorber–reflector selective coatings used in concentrated solar power (CSP) systems for ...
