Growth of nanocolumnar thin films on patterned substrates at oblique angles
(Wiley-VCH Verlag, 2019)
The influence of one dimensional substrate patterns on the nanocolumnar growth of thin films deposited by magnetron sputtering at oblique angles is theoretically and experimentally studied. A well‐established growth model ...

Experimental study on the use of granulometric speciation for the radiometric dating of recent sediments
(Elsevier, 2019)
Theoretical and experimental studies have shown that activity concentrations of fallout radionuclides (such as 137Cs and excess 210Pb) decrease with particles size in aqueous suspensions. This paper is aimed at reviewing ...

Factors related to 41K interference on 41Ca AMS measurements
(ScienceDirect, 2019-01)
Dealing with the 41K interference during 41Ca measurement with low energy AMS systems is challenging. The detection of 39K to correct the measured 41Ca/40Ca ratios is a powerful tool that improves precision and accuracy. ...

Pterobreathers in a model for a layered crystal with realistic potentials: Exact moving breathers in a moving frame
(American Physical Society, 2019-08-12)
In this article we perform a thorough analysis of breathers in a one-dimensional model for a layered silicate for which there exists fossil and experimental evidence of moving excitations along the close-packed lines of ...

Levels of radionuclide concentrations in benthic invertebrate species from the Balearic Islands, Western Mediterranean, during 2012–2018
(Elsevier, 2019-12)
Baseline levels of radionuclides in the marine environment of the Balearic Islands in Western Mediterranean have not been reported in literature. Because of their ecological role and acknowledged sensitivity to pollutants, ...

A Modelling Study on Tsunami Propagation in the Caspian Sea
(Springer, 2019)
A numerical model that simulates the propagation of tsunamis produced by submarine earthquakes was applied to the Caspian Sea. The model was first applied to the June 1990 (Rudbar) earthquake and our results proved to ...

An exploratory modelling study on sediment transport during the Zanclean flood of the Mediterranean
(Springer, 2019)
A nearly 400-km-long erosion channel through the Strait of Gibraltar has been interpreted as evidence for a catastrophic refll of the Mediterranean at the end of the Messinian salinity crisis, 5.33 million years ago. ...

Marine radionuclide transport modelling: Recent developments, problems and challenges
(Elsevier, 2019)
A brief overview of the current status on the subject of numerical modelling of radionuclide transport in the marine environment is given: main transport processes occurring in the sea, basic approaches to solve such ...

Kinetic Energy-induced Growth Regimes of Nanocolumnar Ti Thin Films Deposited by Evaporation and Magnetron Sputtering
(IOP Publishing, 2019)
We experimentally analyze different growth regimes of Ti thin films associated to the existence of kinetic energy-induced relaxation mechanisms in the material's network when operating at oblique geometries. For this ...

Holocene palaeoenvironmental evolution of Saltés Island, Tinto and Odiel estuary, SW Spain, during the Roman period, 1st century BC–5th century AD
(Springer, 2019)
A multidisciplinary analysis of Holocene sediments from Saltés Island (Tinto-Odiel estuary, SW Spain) has allowed to differentiate eigth sedimentary facies, according to their textural characteristics, internal structure, ...
