Portable and Raman imaging usefulness to detect decaying on mortars from Punta Begoña Galleries (Getxo, North of Spain)
(Wiley, 2016-12)
Punta Begoña Galleries were built in 1918 in Getxo (Basque Country, North of Spain) but were abandoned in 1960. Nowadays, their conservation state is very poor. In this work, portable Raman spectroscopy was applied to ...
Ionogel-based Nitrite and Nitrate Sensor for Water Control at the Point-of-Need
(Elsevier, 2016)
The increment of uncontrolled nutrients concentration in water is the subject of increasing environmental concern. In particular, the increment of nitrate causes the eutrophication of algae, leading to fauna and flora ...
Classification of archaeological pieces into their respective stratum by a chemometric model based on the soil concentration of 25 selected elements
(Elsevier, 2010-04-01)
The aim of this work was to demonstrate that an archaeological ceramic piece has remained buried underground in the same stratum for centuries without being removed. For this purpose, a chemometric model based on Principal ...
Diagnosing the traffic impact on roadside soils through a multianalytical data analysis of the concentration profiles of traffic-related elements
(2013-05-16)
The road traffic has become one of the most serious environmental problems in many cities and the main source of pollution of urban soils. To diagnose properly the magnitude of such impacts on roadside soils, eight urban ...
In-situ analytical study of bricks exposed to marine environment using hand-held X-ray fluorescence spectrometry and related laboratory techniques
(Elsevier, 2018-05-03)
In this work, the degradation processes that take place in bricks exposed to marine environments have been studied. Taking into account the importance of this building material where the silicates present in the final ...
Micro-Raman and SEM-EDS analyses to evaluate the nature of salt clusters present in secondary marine aerosol
(Elsevier, 2017-10-17)
Marine aerosol is a complex inorganic and organic chemistry system which contains several salts, mainly forming different type of salt clusters. Different meteorological parameters have a key role in the formation of these ...
Raman spectroscopy assisted with XRF and chemical simulation to assess the synergic impacts of guardrails and traffic pollutants on urban soils
(Wiley, 2012-11-01)
Urban soils are potential reservoirs of toxic metals as a consequence of traffic emissions. Sources like brake linings, tyres, road pavement, exhaust fumes, guardrail, traffic signals and other galvanised steel structures ...
Non-destructive characterisation of the Elephant Moraine 83227 meteorite using confocal Raman, micro-energy-dispersive X-ray fluorescence and Raman-scanning electron microscope-energy-dispersive X-ray microscopies
(Springer, 2018)
The application of a non-destructive analytical procedure to characterise the mineral phases in meteorites is a key issue in order to preserve this type of scarce materials. In the present work, the Elephant Moraine 83227 ...
Non-destructive Screening Methodology based on ED-XRF for the classification of Medieval and post-Medieval Archaeological Ceramics
(Elsevier, 2019-06)
Compositional analysis of ceramics plays a crucial role in Archaeology because following the proper methodology, it enables to obtain knowledge about past human behavior. In this regard, X-Ray Fluorescence Spectrometry ...
Hit and sunk: provenance and alterations of ceramics from seventeenth century Angra D shipwreck
(2020-07-21)
A set of 34 archaeological ceramics, including olive jars, transparent green lead glazed, tin-lead glazed and unglazed ceramics, from seventeenth century Angra D shipwreck found at Terceira Island (Azores Archipelago, ...
