Electron transfer pathways from quantum dynamics simulations
(American Institute of Physic, 2020-12)
This work explores the possibility of simulating an electron transfer process between a donor and an acceptor in real time using time-dependent density functional theory electron dynamics. To achieve this objective, a ...
Dynamics of the active site architecture in plant-type ferredoxin-NADP + reductases catalytic complexes
(Elsevier Science, 2014-06)
Kinetic isotope effects in reactions involving hydride transfer and their temperature dependence are powerful tools to explore dynamics of enzyme catalytic sites. In plant-type ferredoxin-NADP+ reductases the FAD cofactor ...
Revisiting a medical case of "stinging" in the human oral cavity caused by ingestion of raw squid (Cephalopoda: Teuthida): new data on the functioning of squid's spermatophores
(SPRINGERNEW YORK, 2012)
Male squid produce intricate spermatophores that, when transferred to the female, undergo the spermatophoric reaction, a complex process of evagination that leads to the attachment of the spermatangium, that is, the everted ...
Simple fabrication of active electrodes using direct laser transference
(Pergamon-Elsevier Science Ltd., 2014-01)
Direct laser transference (DLT) method is applied to obtain electrodes modified with thin films of conducting polymers (CPs) or catalytic metals. A short (6–10 ns) pulse of laser light (second harmonic of Nd-YAG Laser, λ ...
Dual catalytic performance of arene-ruthenium amine complexes for norbornene ring-opening metathesis and methyl methacrylate atom-transfer radical polymerizations
(2020-05-01)
Arene ruthenium(II) complexes bearing the cyclic amines RuCl2(η6-p-cymene)(pyrrolidine)] (1), [RuCl2(η6-p-cymene)(piperidine)] (2), and [RuCl2(η6-p-cymene)(peridroazepine)] (3) were successfully synthesized. Complexes 1–3 ...
Reconstruction of palaeoprecipitation based on pollen transfer functions e the record of the last 16 ka from Laguna Potrok Aike, southern Patagonia
(Pergamon-Elsevier Science Ltd., 2013-07-01)
Based on modern pollen samples from different vegetation units in southern Patagonia, showing a close relation to yearly amounts of precipitation and mean annual temperatures, different polleneclimate transfer functions ...
Uma abordagem de exploração volumétrica baseada em agrupamento e redução dimensional para apoiar a definição de funções de transferência multidimensionais
(Universidade Estadual Paulista (Unesp), 2018-03-27)
Funções de transferência (FTs) são uma parte crucial do processo de exploração volumétrica em Visualização Direta de Volumes. Nesse processo, FTs desempenham duas tarefas principais: a classificação de materiais e o ...
Proportional controllers: Direct method for stability analysis and MATLAB implementation
(Institute of Electrical and Electronics Engineers (IEEE), 2007-02-01)
In most cases, the cost of a control system increases based on its complexity. Proportional (P) controller is the simplest and most intuitive structure for the implementation of linear control systems. The difficulty to ...

Theoretical exploration of seleno and tellurophenols as promising alternatives to sulfur ligands for anchoring to gold (111) materials
(Royal Soc. Chemistry, 2016)
It is widely known that sulfur ligands, such as alkanethiols or phenothiols and their derivatives, are useful anchor systems for gold materials due to the high affinity of sulfur to gold surfaces. In this study we use DFT ...
