Physicochemical Properties and Proposed Mechanism in the Obtainment of 4-Hidroxycoumarin Conjugated Polymers Using MALDI-Tof Analysis
(International Organization of Scientific Research, 2016-02)
The mechanism for the poly-condensation event of conjugated polymers with ending 4-hydroxycoumarin has been proposed. It happened under H2SO4 acidic conditions only using enolic-coumarins without any substituent at third ...
Análisis metabólico mediante espectrometría de masas MALDI TOF TOF de plántulas de Hylocereus sp (PITAHAYA) sometidas a diferentes condiciones de estrés biótico y abiótico
(Universidad Nacional de Tumbes, 2020)
Las plantas que pertenecen a la familia de las cactáceas hoy en día tienen especial importancia por ser especies que se adaptan a diferentes condiciones agroecológicas, siendo la pitahaya (Hylocereus sp.) un género prominente ...
UV-MALDI-TOF Mass Spectrometry Analysis of Heparin Oligosaccharides Obtained by Nitrous Acid Controlled Degradation and High Performance Anion Exchange Chromatography
(Springer, 2010-01)
Nitrous acid degradation of heparin followed by high-performance anion-exchange chromatography (HPAEC) separation and ultraviolet matrix assisted laser desorption/ionization time-of-flight (UV-MALDI-TOF) analysis led to ...
UV-MALDI-TOF and ESI-TOF Mass Spectrometry Characterization of Silsesquioxanes Obtained by the Hydrolytic Condensation of (3-Glycidoxypropyl)- trimethoxysilane in an Epoxidized Solvent
(Wiley VCH Verlag, 2001-07-01)
Silsesquioxanes obtained by the hydrolytic condensation of (3-glycidoxypropyl)trimethoxysilane (GPMS) in diglycidyl ether of bisphenol A (DGEBA) were characterized by electrospray ionization time-of-flight mass spectrometry ...
Bacillus subtilis subsp. subtilis CBMDC3f with antimicrobial activity against Gram-positive foodborne pathogenic bacteria: UV-MALDI-TOF MS analysis of its bioactive compounds
(Springer, 2015-06)
In this work a new Bacillus sp. strain, isolated from honey, was characterized phylogenetically. Its antibacterial activity against three relevant foodborne pathogenic bacteria was studied; the main bioactive metabolites ...
Classical Characterization Techniques to Reveal the Structural Model of Nanocomposites with Bimetallic Monolayers of Porphyrins
(American Chemical Society, 2016-09-02)
Nanocomposites with bimetallic monolayers of porphyrins were prepared. The well-ordered metalloporphyrin monolayers covalently linked to the gold surface produce an important increase of the B band (∼400 nm) shifted 20 nm ...
Antagonistic effects of Bacillus subtilis subsp. subtilis and B. amyloliquefaciens against Macrophomina phaseolina: SEM study of fungal changes and UV-MALDI-TOF MS analysis of their bioactive compounds
(Elsevier Gmbh, 2016-01)
The antifungal effect of Bacillus subtilis subsp. subtilis PGPMori7 and Bacillus amyloliquefaciens PGPBacCA1 was evaluated against Macrophomina phaseolina (Tassi) Goid. Cell suspension (CS), cell-free supernatant (CFS) and ...
