Non-Destructive Analytical Investigation of Decorative Wallpapers Samples of the Nineteenth Century before Their Restoration
(MDPI, 2021-06-28)
In this work, decorative wallpapers (19th century) from an historical palace located in Oiartzun (Basque Country, Spain) were analyzed before their restoration. Micro-energy dispersive X-ray fluorescence spectroscopy, Raman ...
Behaviour of Vespa velutina nigrithorax (Hymenoptera: Vespidae) under Controlled Environmental Conditions
(MDPI, 2023-01-07)
Vespa velutina, commonly known as the Asian hornet, is an exotic species originating from the Asian continent. It has become an invasive species in Europe due to it being a predator of native fruits and insects, especially ...
Suspect Screening of Chemicals in Hospital Wastewaters Using Effect-Directed Analysis Approach as Prioritization Strategy
(MDPI, 2023-01-26)
The increasing number of contaminants in the environment has pushed water monitoring programs to find out the most hazardous known and unknown chemicals in the environment. Sample treatment-simplification methods and ...
Endocannabinoid 2-Arachidonoylglycerol Synthesis and Metabolism at Neuronal Nuclear Matrix Fractions Derived from Adult Rat Brain Cortex
(MDPI, 2023-02-05)
In this report, we describe the kinetics characteristics of the diacylglycerol lipase-α (DGLα) located at the nuclear matrix of nuclei derived from adult cortical neurons. Thus, using high-resolution fluorescence microscopy, ...
New Generation of SF6-Free Medium-Voltage Switchgear for the Electrical Network: Stability and Toxicity Studies of Trans-1,1,1,4,4,4-Hexafluorobut-2-ene with N2 Gas Mixture
(MDPI, 2023-01-03)
Binary gas mixture of N<sub>2</sub> and trans-1,1,1,4,4,4-hexafluorobut-2-ene (HFO4E) is presented as an alternative to SF6 in medium-voltage electrical equipment. Its stability was tested under different conditions. No ...
HS-SPME-GC/MS Method for the Simultaneous Determination of Trihalomethanes, Geosmin, and 2-Methylisoborneol in Water Samples
(MDPI, 2023-01-21)
Drinking water treatment plants (DWTP) use chlorination as an oxidation stage in the first step of the processes used to eliminate the natural organic matter (NOM) responsible for the formation of 2-methylisoborneol (2-MIB) ...
A Non-Invasive In Situ Spectroscopic Analysis of Cinnabar Minerals to Assist Provenance Studies of Archaeological Pigments
(MDPI, 2023-01-23)
This study presents a non-invasive in situ methodology based on the use of portable elemental (energy dispersive X-ray fluorescence spectroscopy, EDXRF) and molecular (Raman spectroscopy) spectroscopic-based instrumentation ...
Red cinnabar blackening in the mural paintings of Pompeii: volcanic impact, burial environment and atmospheric exposure.
(2022-09-30)
La degradación del pigmento rojo HgS es un problema de conservación que afecta tanto a la forma mineral, denominada cinabrio, como a los pigmentos sintéticos, conocidos como bermellón. El ennegrecimiento se aprecia tanto ...
Understanding Mars through the Earth: Geochemical characterization of submarine volcano scenarios to be used as Martian analogues.
(2020-10-23)
NASA and ESA will carry out their own planetary missions (Mars 2020 and ExoMars 2022 respectively) whose main objective is the demonstration of the potential habitability of the neighbouring planet. In this sense, all the ...
The SuperCam Instrument Suite on the Mars 2020 Rover: Science Objectives and Mast-Unit Description
(Springer, 2021-04)
On the NASA 2020 rover mission to Jezero crater, the remote determination of the texture, mineralogy and chemistry of rocks is essential to quickly and thoroughly characterize an area and to optimize the selection of samples ...
