Estudo teórico da influência de um meio solvente na interação de aminoácidos com um nanotubo de carbono
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2010-09-24)
In this work we use the Density Functional Theory (DFT) to analyze the influence of a water environment in the interaction between amino acids and a semiconductor
carbon nanotube (CNT). To the study of the interaction in ...

Paisagens polares não glaciais (proglacial, paraglacial e periglacial): revisão de conceitos e contribuições da pesquisa pedogeomorfológica brasileira
(Universidade Federal de Minas GeraisBrasilIGC - DEPARTAMENTO DE GEOGRAFIAUFMG, 2019)
The paper proposes a discussion about origin and evolution of proglacial, paraglacial and periglacial concepts. It aims to show diff erentiation of landforms, process, questions and also the critiques that are unique of ...
Subjective time estimation in Antarctica: The impact of extreme environments and isolation on a time production task
(Elsevier Ireland, 2020-04-23)
Interval timing measures time estimation in the seconds-to-minutes range. Antarctica provides a real-world context to study the effect of extreme photoperiods and isolation on time perception. The aim of this study was to ...
A simple analysis of the influence of the solvent-induced electronic polarization on the 15N magnetic shielding of pyridine in water
(Springer, 2012-05)
Electronic polarization induced by the interaction of a reference molecule with a liquid environment is expected to affect the magnetic shielding constants.Understanding this effect using realistic theoretical models is ...
Electrically controlled nuclear polarization of individual atoms
(Nature Publishing Group, 2018-12)
Nuclear spins serve as sensitive probes in chemistry1 and materials science2 and are promising candidates for quantum information processing3–6. NMR, the resonant control of nuclear spins, is a powerful tool for probing ...
