Exploring matrix effects in liquid chromatography–tandem mass spectrometry determination of pesticide residues in tropical fruits
(2015-12-17)
Tropical fruits are being increasingly consumed around the world because of their appreciated characteristics, particularly their high nutritional value and distinctive taste, which are different from those of traditional ...
Bogota River anthropogenic contamination alters microbial communities and promotes spread of antibiotic resistance genes
(Nature Research, 2019)
The increase in antibiotic resistant bacteria has raised global concern regarding the future effectiveness of antibiotics. Human activities that influence microbial communities and environmental resistomes can generate ...
Experimental and theoretical approach of nanocrystalline TiO2 with antifungal activity
(Elsevier, 2013-07-09)
Using a solvothermal method for this research we synthesized nanocrystalline titanium dioxide (nc-TiO2) anatase particles with a mean diameter of 5.4 nm and evaluated their potential antifungal effect against planktonic ...
Exploring the Catalytic Mechanism of the RNA Cap Modification by nsp16-nsp10 Complex of SARS-CoV-2 through a QM/MM Approach
(MDPI, 2021-12-28)
The inhibition of key enzymes that may contain the viral replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have assumed central importance in drug discovery
projects. Nonstructural proteins (nsps) ...
Biexcitons in CdSe nanoplatelets: geometry, binding energy and radiative rate
(Royal Society of Chemistry, 2022-05-13)
Biexciton properties in semiconductor nanostructures are highly sensitive to quantum confinement, relative electron–hole masses, dielectric environment and Coulomb correlations. Here we present a variational Quantum Monte ...
Compression of scheelite-type SrMoO4 under quasi-hydrostatic conditions: Redefining the high-pressure structural sequence
(American Institute of Physics, 2013)
The high-pressure behavior of tetragonal SrMoO4 was analyzed by Raman and optical-absorption measurements. Pressures up to 46.1 GPa were generated using diamond-anvil cells and Ne or N2 as quasi-hydrostatic pressure-transmitting ...
Base-Free Catalytic Hydrogen Production from Formic Acid Mediated by a Cubane-Type Mo3S4 Cluster Hydride
(American Chemical Society, 2022-10-14)
Formic acid (FA) dehydrogenation is an attractive process in the implementation of a hydrogen economy. To make this process greener and less costly, the interest nowadays is moving toward non-noble metal catalysts and ...
Exploring the Origin of Amidase Substrate Promiscuity in CALB by a Computational Approach
(American Chemical Society, 2020)
Enzyme promiscuity attracts the interest of the industrial and academic sectors because of its application in the design of biocatalysts. The amidase activity of Candida antarctica lipase B (CALB) on two different substrates ...
Toward an Understanding of the Hydrogenation Reaction of MO2 Gas-Phase Clusters (M = Ti, Zr, and Hf)
(American Chemical Society, 2013)
A theoretical investigation using density functional theory (DFT) has been carried out in order to understand the molecular mechanism of dihydrogen activation by means of transition metal dioxides MO2 (M = Ti, Zr, and Hf) ...
