New visible light organo(metal)-photocatalyzed fluoroalkylsulfanylation (RFS-) and fluoroalkylselenolation (RFSe-) reactions of organic substrates
(Elsevier Science SA, 2020-12)
The fluoroalkylsulfanyl (RFS-) and fluoroalkylselenolyl (RFSe-) groups are becoming increasingly ubiquitous moieties in synthetic organic transformations on account of their relevance in areas ranging from medicinal chemistry ...
Dynamics of visibility, confidence, and choice during eye movements
(American Psychological Association, 2014-04)
We study the dynamics of objective and subjective measures of visibility and choice in brief presentations occurring within a fixation during free eye-movements. We show that brief presentations yield homogeneous levels ...
Transition-metal-free and visible-light-mediated desulfonylation and dehalogenation reactions: Hantzsch ester anion as electron and hydrogen atom donor
(American Chemical Society, 2020-11)
Novel approaches for N- and O-desulfonylation under room temperature (rt) and transition-metal-free conditions have been developed. The first methodology involves the transformation of a variety of N-sulfonyl heterocycles ...
Thoughts on the Visual Aspect of the Neoliberal Order and the Piquetero Movement in Argentina
(SAGE Publications, 2010-10)
The Argentine piquetero movement of the 1990s, in which unemployed workers blockaded the roads to protest the neoliberal order, has been described as the emergence of a “visibility” that achieved political centrality. ...
Fast photodegradation of Orange II azo dye under visible light irradiation using a semiconducting n-p heterojunction of ZnO nanoparticles/polypyrrole as catalyst
(Springer, 2020-02)
Preparation of innovative nano- and microstructured heterojunctions consisting of two semiconductors for highly efficient p–n photocatalysts has been of growing interest due to their advanced applications. n-type ZnO ...
Photocatalytic paint for fungi growth control under different environmental conditions and irradiation sources
(Elsevier Science Sa, 2018-09)
The fungicide effect employing Aspergillus niger as a representative microorganism was tested applying a Photocatalytic paint formulated with an anatase carbon doped TiO2 and compared with a homemade non-active paint (rutile ...
Electron Donor-Acceptor Complexes in Perfluoroalkylation Reactions
(Wiley VCH Verlag, 2018-12)
Electron-donor-acceptor complexes (EDA) can be established through halogen-bonding interactions between the N lone electron pair from organic bases (or N-/O-centered anions) and perfluoroalkyl iodides RF–I. These EDA ...
Visibility fringe reduction due to noise-induced effects: Microscopic approach to interference experiments
(World Scientific, 2007-12)
Decoherence is the main process behind the quantum to classical transition. It is a purely quantum mechanical effect by which the system loses its ability to exhibit coherent behavior. The recent experimental observation ...
Experimental and Theoretical Study of the High-Temperature UV-Visible Spectra of Aqueous Hydroquinone and 1,4-Benzoquinone
(American Chemical Society, 2016-10)
UV-visible spectroscopic studies of aqueous hydroquinone (HQ) and 1,4-benzoquinone (BQ) have been carried out along with classical molecular dynamics (MD) and quantum calculations. The experimental results confirmed that ...
Veronica Tell, El lado visible. Fotografía y progreso en la Argentina a fines del siglo XIX, Buenos Aires, UNSAM Edita, 2017
(Universidad de Los Andes, 2018-01)
La aparición de un libro de investigación académica siempre es motivo de alegría porque da difusión completa a pesquisas de largo aliento que de otro modo quedarían en fragmentos en diversos journals; pero, en el caso de ...
