Analytical Techniques Applied to the Study of Industrial Archaeology Heritage: The Case of Plaiko Zubixe Footbridge
(MDPI, 2022)
[EN] In this work, micro-Raman spectroscopy and micro-energy-dispersive X-ray fluorescence spectroscopy (µ-EDXRF) were applied on microsamples taken from the Plaiko Zubixe footbridge (1927) located in Ondarroa (Basque ...
Dilute-and-shoot coupled to mixed mode liquid chromatography-tandem mass spectrometry for the analysis of persistent and mobile organic compounds in human urine
(Elsevier, 2023-08)
In this work, a comprehensive method for the simultaneous determination of 33 diverse persistent and mobile organic compounds (PMOCs) in human urine was developed by dilute-and-shoot (DS) followed by mixed-mode liquid ...
Response of Horticultural Soil Microbiota to Different Fertilization Practices
(MDPI, 2020-10-06)
Environmentally friendly agricultural production necessitates manipulation of microbe–plant interactions, requiring a better understanding of how farming practices influence soil microbiota. We studied the effect of ...
Metals and metalloids in high-altitude Pyrenean lakes: sources and distribution in pre-industrial and modern sediments
(Springer, 2023-07)
High-altitude Pyrenean lakes are ecosystems far from local pollution sources, and thus they are particularly sensitive to the
atmospheric deposition of metals and metalloids. This study aims to quantify the effect of human ...
A Liposomal Formulation to Exploit the Bioactive Potential of an Extract from Graciano Grape Pomace
(MDPI, 2022)
Antioxidant compounds with health benefits can be found in food processing residues, such as grape pomace. In this study, antioxidants were identified and quantified in an extract obtained from Graciano red grape pomace ...
Effects of different oenological technologies on the evolution of anthocyanin derivatives determined by LC-MS during red wine fermentations. Encapsulation of phenolic grape pomace extracts for cosmetic applications
(2022-09-23)
This PhD thesis is focused on to two topics related to wine-making: (i) the study of the influence of novel oenological techniques on the phenolic composition of wine during its elaboration, and (ii) the valorization of ...
Untargeted Metabolomic Liquid Chromatography High-Resolution Mass Spectrometry Fingerprinting of Apple Cultivars for the Identification of Biomarkers Related to Resistance to Rosy Apple Aphid
(American Chemical Society, 2022-06-10)
Liquid chromatography high-resolution mass spectrometry fingerprinting together with pattern recognition techniques was used to determine the metabolites involved in the susceptibility of apple cultivars to rosy apple aphid ...
Influence of dispersant application on the toxicity to sea urchin embryos of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas
(Elsevier, 2021-09-09)
This study deals with the toxicity assessment of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas (NNA: Naphthenic North-Atlantic crude oil; MGO: Marine Gas Oil; IFO: ...
Issues with the detection and classification of microplastics in marine sediments with chemical imaging and machine learning
(Elsevier, 2023-09)
Numerous studies have attempted to detect microplastic litter directly in environmental sediments via spectral imaging and powerful classification algorithms. Spectral imaging is attractive largely due to the benefits of ...
Secco painting technique revealed in non-restored Pompeian murals by analytical and imaging techniques
(Elsevier, 2023-09-15)
The fresco technique appears to have been widely used on Roman mural paintings. The close observation of many of such murals suggests, however, the application of a secco technique over the fresco background. In this work, ...
