Microwave-hydrothermal synthesis of single-crystalline Co3O4 spinel nanocubes
(The Royal Society of Chemistry, 2013-07-29)
An efficient microwave-hydrothermal (MAH) method has been developed for the synthesis of highly crystalline Co3O4 spinel nanocubes via beta-Co(OH)(2) without any surfactant assistance. The structure and surface chemical ...
Fast methodology for the reliable determination of nonylphenol in water samples by minimal labeling isotope dilution mass spectrometry
(Elsevier, 2013-08)
In this work we have developed and validated an accurate and fast methodology for the determination of 4-nonylphenol (technical mixture) in complex matrix water samples by UHPLC–ESI-MS/MS. The procedure is based on isotope ...
Are Heme-Dependent Enzymes Always Using a Redox Mechanism? A Theoretical Study of the Kemp Elimination Catalyzed by a Promiscuous Aldoxime Dehydratase
(American Chemical Society, 2020-09-03)
The design of biocatalysts is a goal to improve the rate, selectivity and environmental friendship of chemical processes in biotechnology. In this regard, the use of computational techniques has provided valuable assistance ...
In Situ Growth of Bi Nanoparticles on NaBiO3, delta-, and beta-Bi2O3 Surfaces: Electron Irradiation and Theoretical Insights
(American Chemical Society, 2019-02-04)
Herein, we present a combined experimental and theoretical study of the in situ growth of Bi nanoparticles on NaBiO3, δ-, and β-Bi2O3 surfaces mediated by the electron beam of a high-resolution transmission electron ...

(Elsevier, 2020-07-23)
This article describes the synthesis of α-Ag2W0.75Mo0.25O4 using a coprecipitation method followed by microwave irradiation for different times. The samples were characterized using X-ray and neutron diffractions with ...
Graphene Nanoplatelets: In Vivo and In Vitro Toxicity, Cell Proliferative Activity, and Cell Gene Expression
(MDPI, 2022-01-12)
Multi-layer graphene (2–10 layers), also called graphene nanoplatelets (GNPs), is a carbonbased nanomaterial (CBN) type with excellent properties desirable for many biomedical applications.
Despite the promising advantages ...
Investigation of pharmaceuticals in a conventional wastewater treatment plant: Removal efficiency, seasonal variation and impact of a nearby hospital
(Elsevier, 2021-04-23)
Discharges from the wastewater treatment plants (WWTPs) are among the main sources of contamination to receiving surface water, therefore the quality of treated wastewater needs to be properly monitored. However, not only ...
LC-QTOF MS screening of more than 1,000 licit and illicit drugs and their metabolites in wastewater and surface waters from the area of Bogotá, Colombia
(Springer, 2015-08)
A large screening of around 1,000 emerging contaminants, focused on licit and illicit drugs and their metabolites, has been made in urban wastewaters (both influent and effluent) and surface waters from the area of Bogotá, ...
Degradation of seventeen contaminants of emerging concern in municipal wastewater effluents by sonochemical advanced oxidation processes
(Elsevier, 2019)
The simultaneous degradation of seventeen emerging concern pollutants in effluent
from the municipal wastewater treatment plant (MWTP) of Bogotá-Colombia was
studied using high frequency ultrasound (375 kHz). The considered ...
