A Two-Wired Ultra-High Input Impedance Active Electrode
(Institute of Electrical and Electronics Engineers, 2018-04)
This paper presents a novel two-wired active electrode that achieves ultrahigh input impedance using power supply bootstrapping. The proposed circuit reduces the input capacitance of a buffer amplifier while enabling ...
An energy-efficient hierarchical architecture for time-interleaved SAR ADC
(Institute of Electrical and Electronics Engineers, 2019-06)
An energy-efficient sampling architecture for time interleaved (TI) successive approximation register (SAR) analog-to-digital converters (ADCs) is proposed. The architecture avoids the use of sampling buffers in order to ...
Purinergic Signaling Controls Spontaneous Activity in the Auditory System throughout Early Development
(Society for Neuroscience, 2021-01)
Spontaneous bursts of electrical activity in the developing auditory system arise within the cochlea before hearing onset and propagate through future sound-processing circuits of the brain to promote maturation of auditory ...
Quantification of neurotransmitters and metabolically related compounds at glassy carbon electrodes modified with bamboo-like carbon nanotubes dispersed in double stranded DNA
(Elsevier Science, 2017-01)
This work reports the application of glassy carbon electrodes (GCE) modified with bamboo-like carbon nanotubes (bCNT) dispersed in calf-thymus double-stranded DNA (dsDNA) (GCE/bCNT-dsDNA) for the highly sensitive and ...
Multi-walled carbon nanotubes functionalized with bathocuproinedisulfonic acid: Analytical applications for the quantification of Cu(II)
(Springer Heidelberg, 2020-08)
This work reports the successful non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with bathocuproinedisulfonic acid (BCS) and the analytical application of the resulting dispersion (MWCNTs-BCS) to ...
Characterization of anodic growth and dissolution of antimony oxide films
(Elsevier Science Sa, 2009-07)
The anodic growth, morphology and stability of antimony oxide films grown in buffered phosphate electrolytes has been characterized by electrochemical methods, in situ ellipsometry and atomic force microscopy. The anodic ...
Single-walled carbon nanotubes covalently functionalized with cysteine: A new alternative for the highly sensitive and selective Cd(II) quantification
(Elsevier Science Sa, 2017-10)
This work is focused on the development of an electrochemical sensor for the quantification of Cd(II) based on the use of glassy carbon electrodes (GCE) modified with a dispersion of single-walled carbon nanotubes (SWCNTs) ...
Stem and leaf hydraulics of congeneric tree species from adjacent tropical savanna and forest ecosystems
(Springer, 2008-12)
Leaf and stem functional traits related to plant water relations were studied for six congeneric species pairs, each composed of one tree species typical of savanna habitats and another typical of adjacent forest habitats, ...
Cysteine functionalized bio-nanomaterial for the affinity sensing of Pb(II) as an indicator of environmental damage
(Elsevier Science, 2018-09)
This work aims at the development of an electrochemical affinity biosensor for Pb(II) quantification using a platform that combines glassy carbon electrodes (GCE) and an aqueous dispersion of single-walled carbon nanotubes ...
Impacto del cambio del estatus sanitario en la ganadería bovina Patagónica
(Asociación Argentina de Economía Agraria, 2019)
La Patagonia Argentina es desde marzo 2013, resoluciones 141/2013 del Ministerio de Agricultura y resolución 82/2013 del SENASA, libre de aftosa sin vacunación. Estatus sanitario que permite ingresar a un circuito comercial ...
