Pesticide residues and transformation products in groundwater from a Spanish agricultural region on the Mediterranean Coast
(Taylor & Francis, 2008)
An overview is given on the presence and changes over time of pesticide residues in
groundwater from the Valencia region, one of the most important citrus cultivation sites of
southern Europe. A multiresidue LC-MS/MS ...
Coupled donors in quantum dots: quantum size and dielectric mismatch effects
(American Physical Society, 2009)
Spatial and dielectric confinement modulations of the spontaneous emission rates, transition energies, and charge-density distributions of a singly ionized double donor system (D2+) in a spherical quantum dot are calculated ...
Determination of sub-ppb epichlorohydrin levels in water by on-line solid-phase extraction liquid chromatography/tandem mass spectrometry
(John Wiley, 2009-06)
A new sensitive and selective method based on on-line solid-phase extraction (SPE) coupled to liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) using a triple quadrupole mass spectrometer ...
Study of biological properties of gold nanoparticles: Low toxicity, no proliferative activity, no ability to induce cell gene expression and no antiviral activity
(Elsevier, 2023-07-26)
Gold nanoparticles (AuNPs) are a fundamental building block of many applications across nanotechnology as they have excellent biosafety which make them promising for a broad range of biomedical applications. Here we explore ...
Strong configuration mixing due to dielectric confinement in semiconductor nanorods
(American Physical Society, 2009)
The interaction between electron-electron and electron-hole pairs in semiconductor nanorods embedded in dielectric media is investigated using a configuration-interaction method. Contrary to spherical quantum dots of similar ...
Experimental and theoretical investigation of ThGeO4 at high pressure
(American Physical Society, 2009)
We report here the combined results of angle-dispersive x-ray diffraction experiments performed on ThGeO4 up to 40 GPa and total-energy density-functional theory calculations. Zircon-type ThGeO4 is found to undergo a ...
Tamoxifen monitoring studies in breast cancer patients by micellar liquid chromatography
(Springer Verlag, 2010)
A simple micellar liquid chromatographic procedure is described to determine tamoxifen in plasma. To perform the analysis, tamoxifen solutions were diluted in water and UV- irradiated for 20 min to form the photocycled ...
Characterization of commercial synthetic resins by pyrolysis-gas chromatography/mass spectrometry : application to modern art and conservation
(American Chemical Society, 2009-04-15)
To characterize a set of synthetic resins, a methodology by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) has been developed. The studied reference materials were commercial versions of a wide range of synthetic ...
Monitoring of HAART regime antiretrovirals in serum of acquired immunodeficiency syndrome patients by micellar liquid chromatography
(Royal Society of Chemistry, 2012-07)
A methodology based on micellar liquid chromatography to monitor five antiretroviral drugs (lamivudine, stavudine, tenofovir, zidovudine and efavirenz) was proposed. Antiretrovirals were studied in sets of three, corresponding ...
Use of Micellar Liquid Chromatography to Determine Mebendazole in Dairy Products and Breeding Waste from Bovine Animals
(MDPI, 2020-02-14)
Mebendazole is an anthelmintic drug used in cattle production. However, residues may occur in produced food and in excretions, jeopardizing population health. A method based on micellar liquid chromatography (MLC) was ...
