Mechanisms of irreversible decoherence in solids
(American Physical Society, 2017-06)
Refocalization sequences in nuclear magnetic resonance (NMR) can in principle reverse the coherent evolution under the secular dipolar Hamiltonian of a closed system. We use this experimental strategy to study the effect ...

Single spin resonance driven by electric modulation of the g-factor anisotropy
(American Physical Society, 2019-12)
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunneling microscope. Several mechanisms have been proposed so far, some of them based on the modulation ...
Pharmaceutical polymorphism of a 5´-O-oxalatoyl prodrug of zidovudine (azidothymidine)
(Open Science Publishers LLP, 2020-03)
The importance of polymorphism in pharmaceuticals makes its study relevant. The aim of this study was to investigate the solid-state forms in which 3´-azido-2´,3´-dideoxi-5´-O-oxalatoyl-thymidinic acid (AZT-Ac), a zidovudine ...
Investigating a soluble pharmaceutical salt: Albendazole Hydrochloride
(American Chemical Society, 2019-08)
Albendazole is an effective antihelmintic drug, which has an unpredictable therapeutic response due to its low solubility in biological fluids that limits its oral absorption. In an attempt to improve solubility, albendazole ...
Transiently trapped entanglements in model polymer networks
(American Chemical Society, 2009-06)
The relaxational dynamics of trapped entanglements in model silicone polymer networks is studied through the residual dipolar couplings (RDC) obtained by double quantum nuclear magnetic resonance (DQ NMR). These experiments ...
Antithrombogenic properties of bioconjugate streptokinase-polyglycerol dendrimers
(Springer, 2005-05-28)
Dendrimers are monodisperse, spherical and hyperbranched synthetic macromolecules with a large number of surface groups that have the potential to act as carriers for drug immobilization by covalent binding or charge ...
Near infrared spectroscopy and multivariate curve resolution-alternating least squares incorporating 13C-NMR information for monitoring epoxy resins reactions
(John Wiley & Sons Ltd, 2007-09-19)
This paper describes how data from two instrumental techniques - near infrared spectroscopy (NIR) and 13C nuclear magnetic resonance ( 13C-NMR) - are combined by means of multivariate curve resolution-alternating least ...
