Preparation and characterization of a Staphylococcus aureus capsular polysaccharide-protein conjugate prepared by a low cost technique: a proof-of-concept study
(2015-01)
Staphylococcus aureus is a worldwide distributed pathogen that produces several diseases in many species and is the major cause of mastitis in dairy cows. S. aureus capsular polysaccharide 5 (CP5) has been widely proposed ...
Comparison of the Kinetics of Electron Transfer in the Diffusion Limit for the Singlet and Triplet Quenching of Eosin Y by Quinones
(Wiley, 2013-06)
Electron transfer (ET) rate constants were determined by means of lifetime measurements for the fluorescence quenching and by laser flash photolysis for the triplet quenching of the dye eosin Y by benzoquinones in acetonitrile. ...
Synthesis of Conjugated Polymer Based in Zn(II) Porphyrin Bearing Terminal Alkynyl Groups as Photosensitizer
(Molecular Diversity Preservation International, 2020-11)
5,10,15,20-tetrakis-[4-(ethynyl)phenyl]porphyrin (TEP) was synthesized from the condensation of 4-(ethynyl)benzaldehyde and pyrrole catalyzed by boron trifluoride diethyl etherate in dichloromethane (DCM). After oxidation ...
Genome-wide overview of Trichosporon akiyoshidainum HP-2023, new insights into its mechanism of dye discoloration
(Springer, 2019-02)
Trichosporon akiyoshidainum HP-2023 completely discolorised Reactive Black 5 (200 mg/l) in 24 h. Manganese peroxidase and phenoloxidase, but no laccase activities were detected throughout the incubation. Total aromatic ...
Arenium cation or radical cation? An insight into the cyclodehydrogenation reaction of 2-substituted binaphthyls mediated by Lewis acids
(Royal Society of Chemistry, 2020-06)
Perylene and its derivatives are some of the most interesting chromophores in the field of molecular design. One of the most employed methodologies for their synthesis is the cyclodehydrogenation of binaphthyls mediated ...
Photophysics and photochemistry of porphyrin core PAMAM dendrimers. Excited states interaction with quinones
(Elsevier Science Sa, 2020-02)
Quenching of excited states of the meso-substituted tetraphenyl porphyrins with PAMAM branches, and one with PAMAM generation 1 peripherally-modified with thiazole groups by p-benzoquinones, were studied in DMF solution. ...
Continuous-flow/stopped-flow system using an immunobiosensor for quantification of human serum IgG antibodies to Helicobacter pylori
(Academic Press Inc Elsevier Science, 2005-02)
Conventional methods, such as gastric biopsy, enzyme-linked immunosorbent assay (ELISA), culture, require a long time for the determination of Helicobacter pylori infections. This study reports an amperometric immunoreactor ...
Paracetamol removal by photo-Fenton processes at near-neutral pH using a solar simulator: Optimization by D-optimal experimental design and toxicity evaluation
(Elsevier Science Sa, 2020-06)
This study discusses the degradation of paracetamol (PCT) by Fenton and photo-Fenton reactions at circumneutral pH with the aid of ferrioxalate and a solar simulator as the light source. The influence of three main operating ...

(Wiley Blackwell Publishing, Inc, 2013-11)
Electron transfer (ET) rate constants were determined by means of lifetime measurements for the fluorescence quenching and by laser flash photolysis for the triplet quenching of the dye eosin Y by benzoquinones in acetonitrile. ...
Bioinspired Functional Catechol Derivatives through Simple Thiol Conjugate Addition
(Wiley VCH Verlag, 2019-09-06)
The combination of the surface-adhesive properties of catechol rings and functional moieties conveying specific properties is very appealing to materials chemistry, but the preparation of catechol derivatives often requires ...
