André Fredi’s oral presentation at 8th GERMN / 5th Iberian NMR Meeting

André Fredi made an oral presentation at the 8th GERMN / 5th Iberian NMR Meeting (GERMN 2016) held in Valencia, Spain from 27th to 29th June 2016.

In his presentation, that was titled  Exploring the use of Generalized Indirect Covariance to reconstruct Pure Shift NMR spectra: Current Pros and Cons”, André explained how to make pure spectra shift from Generalized Indirect IMG-20160628-WA0028Covariance processing (psGIC). This new method is basically a new way to get “synthetic” pure shift spectra without the need to purchase a pure shift spectrum in the spectrometer and without the penalties that pure-shift experiments cause.

André has been working as a Ph.D. candidate at the Department of Chemistry and SeRMN under the direction of Dr. Teodor Parella and Dr. Pau Nolis since November 2014, when he enrolled in the Department of Chemistry doctoral program at Universitat Autònoma de Barcelona with a fellowship from CNPq-Brazil. He is currently in his second year and expects to defend the doctoral thesis on 2017/2018.

Title: Exploring the use of Generalized Indirect Covariance to Reconstruct Pure shift NMR Spectra: Current Pros and Cons.
Authors: André Fredi, Pau Nolis, Carlos Cobas, Gary E. Martin and Teodor Parella.
DOI: 10.1016/j.jmr.2016.03.003

ABSTRACT: The current pros and cons of a processing protocol to generate pure chemical shift NMR spectra using Generalized Indirect Covariance are presented and discussed. The transformation of any standard 2D homonuclear and heteronuclear spectrum to its pure shift counterpart by using a reference DIAG spectrum is described.

SeRMN gets a visit of Gustavo G. Simamoto from UNICAMP-Brazil

AvMmMO19F-_NOP6OnHN_BVnx8QEv3yIaDjCf-B76l4EEWe received a visit from Gustavo Giraldi Shimamoto who is PhD student and technical NMR at University of Campinas (UNICAMP-Brazil). Gustavo was one month (November 2015) in our laboratory learning a little about how our NMR service works, the type of service we provide both to universities and to companies and some of our routine work. In addition, Gustavo learned about pulse sequence, modern NMR experiments as pure-shift and HSQMBC. For us it was a great pleasure to receive and meet Gustavo.
