Experimental Setup of the Fast Current Controller for the Buenos Aires Heavy Ion Microbeam
(Molecular Diversity Preservation International, 2019-06-03)
Recently we used the heavy ion microprobe of the Buenos Aires TANDAR Laboratory for Single Event Effects (SEE) and Total Dose (TD) experiments in electronics devices and components, requiring very low beam currents. The ...
A role for β,β-xanthophylls in Arabidopsis UV-B photoprotection
(Oxford University Press, 2018-09)
Plastidial isoprenoids, such as carotenoids and tocopherols, are important anti-oxidant metabolites synthesized in plastids from precursors generated by the methylerythritol 4-phosphate (MEP) pathway. In this study, we ...
Hyperuniform vortex patterns at the surface of type-II superconductors
(American Physical Society, 2019-10)
A many-particle system must possess long-range interactions in order to be hyperuniform at thermal equilibrium. Hydrodynamic arguments and numerical simulations show, nevertheless, that a three-dimensional elastic-line ...
Evaluación citomolecular del efecto vecindad en fibroblastos de pulmón humano bajo condiciones de exposición radioterapéuticaCytomolecular evaluation of bystander effect in human lung fibroblast cells under conditions of radiotherapeutical exposition
(Sociedad Española de Física Médica, 2008-02)
Durante los últimos años uno de los principales paradigmas de la radiobiología ha ido cambiando. Originalmente, se creía que sólo aquellas células irradiadas directamente podrían presentar daño en su material genético. ...
Picosecond laser interference patterning of periodical micro architectures on metallic molds for hot embossing
(Multidisciplinary Digital Publishing Institute, 2019-10-18)
In this work, it is demonstrated that direct laser interference patterning (DLIP) is a method capable of producing microtextured metallic molds for hot embossing processes. Three different metals (Cr, Ni, and Cu), relevant ...
Stronger bonds bring bigger challenges
(American Association for the Advancement of Science, 2020-07)
For organic chemists, synthesizing complex molecules in a few steps without waste and with minimal energy has been a long-standing challenge. In many cases, synthetic methodology now enables the design of straightforward ...
DNA damage induced by photoexcited bare and loaded Microporous Coordination Polymers
(Royal Society of Chemistry, 2015-05)
We report on interactions of cell free double-stranded DNA (dsDNA) with a selected subgroup of Microporous Coordination Polymers (MCPs). In particular, we have studied the influence of different metal ion constituents and ...
Exploiting electron storage in TiO2 nanoparticles for dark reduction of As(v) by accumulated electrons
(Royal Society Of Chemistry, 2013-05)
UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift. Direct evidence that the accumulated charges can drive the otherwise forbidden reduction of ...
Photostability of gold nanoparticles with different shapes: the role of Ag clusters
(Royal Society of Chemistry, 2015-07)
Anisotropic gold nanostructures prepared by the seed method in the presence of Ag ions have been used to study their photostability to low-power UV irradiation (254 nm) at room temperature. It has been observed that, whereas ...
Visible Light-Promoted C-C Bond Formation from Hydroxyaryls in Water
(Csiro Publishing, 2019-11)
An eco-friendly and direct arylation of hydroxyaryls in water using photoinduced reactions with different substrates (1-bromo-2-naphthol, 1-iodo-2-naphthol, N-(2-iodophenyl)acetamide, 5-bromouracil, 2-iodo-N-methylbenzamide, ...
