Treatment of wastewater effluents from Bogotá – Colombia by the photo-electro-Fenton process: Elimination of bacteria and pharmaceutical
(Elsevier, 2021)
In this work, the occurrences of bacteria families and relevant pharmaceuticals in municipal wastewater effluents from Bogotá (Colombia), and their treatment by the photo-electro-Fenton process were studied. Twenty-five ...
Dynamics and Reactivity in Thermus aquaticus N6-Adenine Methyltransferase
(American Chemical Society, 2014)
M.TaqI is a DNA methyltransferase from Thermus aquaticus that catalyzes the transfer of a methyl group from S-adenosyl-l-methionine to the N6 position of an adenine, a process described only in prokaryotes. We have used ...
Air-Stable, Well-Soluble AI2[Nb6Cl18] Cluster Compounds (AI = Organic Cation): A New Route for Preparation, Single-Crystal Structures, Properties, and ESI-Mass Spectra
(Wiley, 2016-04)
Five niobium cluster compounds of the AI2[Nb6Cl18] type (AI = organic cation: [nPr4N]+, [nBu4N]+, [BMIm]+, [Ph4P]+, and [PPN]+) are obtained through treatment of [Nb6Cl14(H2O)4]·4H2O with excess of thionyl chloride in the ...
Experimental and Theoretical Study on the Structure, Optical Properties, and Growth of Metallic Silver Nanostructures in Ag3PO4
(American Chemical Society, 2015-02)
Theoretical and experimental studies were performed on the structure, optical properties, and growth of silver nanostructures in silver phosphate (Ag3PO4). This material was synthesized by the coprecipitation method and ...
On the use of ionic liquids as mobile phase additives in high-performance liquid chromatography. A review
(Elsevier, 2015-07-07)
The popularity of ionic liquids (ILs) has grown during the last decades in several analytical separation techniques. Consequently, the number of reports devoted to the applications of ILs is still increasing. This review ...
Fast gas chromatographic residue analysis in animal feed using split injection and atmospheric pressure chemical ionisation tandem mass spectrometry
(Elsevier, 2015-11)
Significant speed improvement for instrumental runtime would make GC–MS much more attractive for determination of pesticides and contaminants and as complementary technique to LC–MS. This was the trigger to develop a fast ...
Enzyme Molecular Mechanism as a Starting Point to Design New Inhibitors: A Theoretical Study of O-GlcNAcase
(ACS, 2011-05)
O-Glycoprotein 2-acetamino-2-deoxy-β-d-glucopyranosidase (O-GlcNAcase) hydrolyzes O-linked 2-acetamido-2-deoxy-β-d-glucopyranoside (O-GlcNAc) residues from post-translationally modified serine/threonine residues of ...
Electronic fluxes during diels-alder reactions involving 1,2-Benzoquinones: mechanistic insights from the analysis of electron localization function and catastrophe theory
(Wiley-Blackwell, 2012)
By means of the joint use of electron localization function (ELF) and Thom's catastrophe theory, a theoretical analysis of the energy profile for the hetero-Diels-Alder reaction of 4-methoxy-1,2-benzoquinone 1 and ...
Stability indicating MLC method for three novel deriviatives of zidovudine in aqueous and simulated gastric and intestinal fluids.
(© 2011 Elsevier, 2011-05)
This work studies the stability of three new anti-HIV agents which were obtained by the association of zidovudine (AZT) with different amino acids, such as leucine (AZT-Leu) and valine (AZT-Val), and one with an acid group ...
