A Synthetic Quality Index to Evaluate the Functional Stability of Soil Microbial Communities After Perturbations
(Elsevier, 2021-05-28)
[Abstract] Soil stability includes both resistance, the ability to withstand a perturbation or stress, and resilience, the ability to recover to pre perturbation levels. The functional stability of soil microbial communities ...
Modeling the Natural Gas Knocking Behaviour Using Gas-Phase Infrared Spectra and Multivariate Calibration
(Elsevier, 2021-04-01)
[Abstract] To assess the knocking properties of natural gas (NG) when it is used as fuel for vehicles is vital to optimize the design and functioning of their motors. Analytical efforts in this field are needed as the ...
Polycyclic Aromatic Hydrocarbons Analysis in Tea Infusions and Tea Beverages Using Membrane Assisted Solvent Extraction
(Elsevier, 2021-04-16)
[Abstract] Membrane Assisted Solvent Extraction (MASE) was applied as an extraction and enrichment technique of polycyclic aromatic hydrocarbons (PAHs) from tea infusions and fruit/herbal-tea beverages. PAHs have been ...
Development and Validation of a Multi-Pollutant Method for the Analysis of Polycyclic Aromatic Hydrocarbons, Synthetic Musk Compounds and Plasticizers in Atmospheric Particulate Matter (PM₂.₅)
(Elsevier, 2021-07-18)
[Abstract] Exposure to atmospheric particulate matter (PM) associated pollutants is a global concern due to the risk posed in human health after inhalation. In this study, a simple and sensitive multi-residue method is ...
Monitorization of Polyamide Microplastics Weathering Using Attenuated Total Reflectance and Microreflectance Infrared Spectrometry
(Elsevier, 2021-07-10)
[Abstract] The EU goal to reduce marine plastic litter by ca. 30% by 2020 stressed the need to deploy analytical methods to ascertain the polymeric nature of a residue. Furthermore, as plastics age under natural conditions ...
Study of Temporal Variations of Equivalent Black Carbon in a Coastal City in Northwest Spain Using an Atmospheric Aerosol Data Management Software
(MDPI AG, 2021-01-07)
[Abstract]
Light-absorbing carbonaceous aerosols (including black carbon (BC)) pose serious health issues and play significant roles in atmospheric radiative properties. Two-year measurements (2015–2016) of aerosol light ...
Intercomparison and characterization of 23 Aethalometers under laboratory and ambient air conditions: procedures and unit-to-unit variabilities
(Copernicus Publications, 2021-04-30)
[Abstract]:
Aerosolized black carbon is monitored worldwide to quantify its impact on air quality and climate. Given its importance, measurements of black carbon mass concentrations must be conducted with instruments ...
A Sensor-Based Methodology to Differentiate Pure and Mixed White Tequilas Based on Fused Infrared Spectra and Multivariate Data Treatment
(MDPI, 2021-02-27)
[Abstract]: Mexican Tequila is one of the most demanded import spirits in Europe. Its fast-raising worldwide request makes counterfeiting a profitable activity affecting both consumers and legal distillers. In this paper, ...
Evolution of Gaseous and Particulate Pollutants in the Air: What Changed after Five Lockdown Weeks at a Southwest Atlantic European Region (Northwest of Spain) Due to the SARS-CoV-2 Pandemic?
(MDPI, 2021-04-27)
[Abstract] Due to the exponential growth of the SARS-CoV-2 pandemic in Spain (2020), the Spanish Government adopted lockdown measures as mitigating strategies to reduce the spread of the pandemic from 14 March. In this ...
Fast Quality Control of Natural Gas for Commercial Supply and Transport Utilities
(Elsevier, 2021-07-28)
[Abstract] Quality control of natural gas frequently relies on off-line slow standardized chromatographic techniques. Previous implementations of new measurement approaches focused of synthetic mixtures without extensive ...
