High resolution mass spectrometry-based screening for the comprehensive investigation of organic micropollutants in surface water and wastewater from Pasto city, Colombian Andean highlands
(Elsevier, 2024)
The complexity of the aquatic environment scenario, including the impact of urban wastewater, together with the huge number of potential hazardous compounds that may be present in waters, makes the comprehensive characterization ...
Discovery of polycyclic aromatic acid metabolites in fish exposed to the petroleum compounds 1-methylphenanthrene and 1,4-dimethylphenanthrene
(Elsevier, 2024)
Most of the polycyclic aromatic hydrocarbons (PAHs) in petroleum are alkylated (alkyl PAHs), still the metabolism of these alkyl PAHs to the expected acid products (polycyclic aromatic acids; PAAs) has yet to be demonstrated ...
Structural investigation and sonophotocatalytic properties of the solid solutions Sr(Mo1−xWx)O4 crystals synthesized by the sonochemical method
(Springer, 2022-09-18)
In this paper, the solid solutions of strontium molybdate-tungstate [Sr(Mo1−xWx)O4] crystals with (x = 0, 0.25, 0.50, 0.75, and 1) were synthesized by the sonochemical method. Their structure, morphology, optical, and ...
Antiviral leather: A functional coating based on SiO2-AgNPs to eliminate pathogens
(Elsevier, 2023-09-12)
A bovine leather material functionalized with SiO2-Ag nanoparticles (NPs) composite, which possesses highly efficient antimicrobial activity against the SARS-CoV-2 virus and Staphylococcus aureus (S. aureus) bacteria, has ...
Biocompatibility and inflammatory response of silver tungstate, silver molybdate, and silver vanadate microcrystals
(2023)
Silver tungstate (α-Ag2WO4), silver molybdate (β-Ag2MoO4), and silver vanadate
(α-AgVO3) microcrystals have shown interesting antimicrobial properties.
However, their biocompatibility is not yet fully understood. ...
Behavior of Bi2S3 under ultrasound irradiation for Rhodamine B dye degradation
(Elsevier, 2021-10-16)
In this study, we have demonstrated that Bi2S3 semiconductor under ultrasound behaves as a piezoelectric material, facilitating the transfer of electrons and holes, thus enabling the formation of oxidizing agents. In the ...

(American Chemical Society, 2021-12-26)
The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus-2, SARS-CoV-2, shows the need for effective antiviral treatments. Here, we present a simulation study of the inhibition of the SARS-CoV-2 ...
Bactericidal activity of Ag4V2O7/β-AgVO3 heterostructures against antibiotic-resistant Klebsiella pneumoniae
(Elsevier, 2022-10)
Although Ag-based materials are efficient against antibiotic-resistant bacteria, their high toxicity to living organisms represents a major challenge for obtaining useful products. In this work, we report the bactericidal ...
A method to determine two antibiotics prescribed to treat nosocomial infections in plasma and urine by micellar liquid chromatography
(Elsevier, 2023-06-07)
Combined prescription of the antimicrobial drugs linezolid and meropenem is a common strategy to treat multidrug-resistant nosocomial infections. We propose an innovative method to determine these two drugs in plasma and ...
