A non-ionic gadolinium complex whose relaxometric behavior is sensitive to the variation of pH: An experimental and theoretical study on geometry, bonding nature of polyaminocarboxylic ligand and their gadolinium complex
(Bentham Science Publishers, 2018-10)
Background: In addition, the contribution of cyclic structure to the stability of lanthanide complexes has been evaluated on different ligand platforms and some indications of their relative stability are now available. ...
NMR relaxometry analysis of molecular degradation in internal combustion engine lubricants
(John Wiley & Sons Ltd, 2021-04)
A set of experimental techniques headed by proton fast field-cycling nuclear magnetic resonance (1HFFC-NMR) were used to analyze the effects of degradation of lubricant oil used in an internal combustion engine (ICE). Its ...
Monitoring lubricant oil degradation using field-cycling NMR relaxometry
(Taylor & Francis Ltd, 2019-04-30)
Proton fast field-cycling nuclear magnetic resonance (1 HFFC-NMR) was used to study the effect of thermal stress in mineral base oil. The base oil underwent controlled thermal degradation and its relaxometric response was ...
Dynamical regimes of lipids in additivated liposomes with enhanced elasticity: A field-cycling NMR relaxometry approach
(Elsevier Science, 2017-09)
We study the molecular dynamics of lipids in binary large unilamellar liposomes suspended in D2O composed of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) or soy phosphatidylcholine (SPC) additivated with different ...
The Effect of Cholesterol on Membrane Dynamics on Different Timescales in Lipid Bilayers from Fast Field-Cycling NMR Relaxometry Studies of Unilamellar Vesicles
(Wiley VCH Verlag, 2014-01)
The general applicability of fast field-cycling nuclear magnetic resonance relaxometry in the study of dynamics in lipid bilayers is demonstrated through analysis of binary unilamellar liposomes composed of 1,2-dioleo ...
Design of PLGA Based Nanoparticles for Imaging Guided Applications
(American Chemical Society, 2014-09)
An amphiphilic Gd(III) complex has been efficiently loaded in polylactic-co-glycolic acid nanoparticles (PLGA-NPs) to yield a novel, high sensitive magnetic resonance imaging (MRI) contrast agent for imaging guided drug ...
Monitoramento do Biosorvente Quitosana por Ressonância Magnética Nuclear no Domínio do Tempo (RMN-DT) em Emulsões de Petróleo
(Universidade Federal do Espírito SantoBRMestrado em QuímicaPrograma de Pós-Graduação em QuímicaUFES, 2013-02-28)
Petrochemical accidents have attracted great notoriety in the scientific community due to environmental damage caused by the spread of oil, both in offshore and onshore environments. The present study carried out petrochemical ...
