Electrostatically Driven Second-Sphere Ligand Switch between High and Low Reorganization Energy Forms of Native Cytochrome c
(Amer Chemical Soc, 2013-03)
We have employed a combination of protein film voltammetry, time-resolved vibrational spectroelectrochemistry and molecular dynamics simulations to evaluate the electron-transfer reorganization free energy (λ) of cytochrome ...
Estudio de fallas en fuentes de alimentación conmutadas debido al estrés de los capacitores electrolíticos
(Universidad Nacional de Misiones. Facultad de Ingeniería. Secretaría de Ciencia y Técnica, 2019-06-21)
Este trabajo enmarcado en un proyecto de investigación acreditado, tuvo como objetivo determinar las principales causas de fallas en fuentes conmutadas o switching. En un 83% de los casos analizados los resultados empíricos ...
Physical Interactions Driving the Activation/Inhibition of Calcium/Calmodulin Dependent Protein Kinase II
(Elsevier Science Inc., 2021-06)
CaMKII is a protein kinase whose function is regulated by the binding of the Calcium/Calmodulin complex (Ca2+ /CaM). It is a major player in the Long Term Potentiation process where it acts as a molecular switch, oscillating ...
Electronic mechanism for resistive switching in metal/insulator/metal nanodevices
(Iop Publishing Ltd, 2020-07-15)
Passing current at given threshold voltages through a metal/insulator/metal sandwich structure device may change its resistive state. Such switching has been rationalized by ion drift models, or changes in electronic states, ...
Surface charge effects on the redox switching of LbL self-assembled redox polyelectrolyte multilayers
(Elsevier Science Sa, 2007-01-15)
The effect of surface charge on the electron transfer and charge propagation in layer by layer (LbL) electrostatically self-assembled redox poly-electrolyte multilayers (PEMs) has been studied. Thin films comprised of ...
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 ...
Reversible Switching of the Dirac Point in Graphene Field-Effect Transistors Functionalized with Responsive Polymer Brushes
(American Chemical Society, 2019-06)
The reversible control of the graphene Dirac point using external chemical stimuli is of major interest in the development of advanced electronic devices such as sensors and smart logic gates. Here, we report the coupling ...
