Topology of Pretreated Wood Fibers Using Dynamic Nuclear Polarization

David Lyndon Emsley, Jeremy Luterbacher, Arthur César Pinon, Pierrick Berruyer, Jasmine Viger-Gravel, Wu Lan, Michel Bardet

In the continuously developing field of lignocellulosic biomass, high-yield lignin depolymerization processes are sought to optimize its productivity and profitability. Recently, formaldehyde stabilization during lignin extraction and biomass pretreatment ...

Structure of Lipid Nanoparticles Containing siRNA or mRNA by Dynamic Nuclear Polarization-Enhanced NMR Spectroscopy

David Lyndon Emsley, Aaron James Rossini, Arthur César Pinon, Jasmine Viger-Gravel

Here, we show how dynamic nuclear polarization (DNP) NMR spectroscopy experiments permit the atomic level structural characterization of loaded and empty lipid nanoparticles (LNPs). The LNPs used here were synthesized by the microfluidic mixing technique a ...

BDPA-Nitroxide Biradicals Tailored for Efficient Dynamic Nuclear Polarization Enhanced Solid-State NMR at Magnetic Fields up to 21.1 T

David Lyndon Emsley, Aaron James Rossini, Dominik Józef Kubicki, Arthur César Pinon, Moreno Lelli, Georges Guévork Jean-Jacques Menzildjian, David Benjamin Roger Antoine Gajan

Dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) has developed into an invaluable tool for the investigation of a wide range of materials. However, the sensitivity gain achieved with many polarizing agents suffers from an unf ...

Spin Diffusion in Dynamic Nuclear Polarization Nuclear Magnetic Resonance

Arthur César Pinon

Dynamic Nuclear Polarization (DNP) is currently one of the most efficient ways of enhancing sensitivity in solid-state Nuclear Magnetic Resonance (NMR) experiments. The DNP protocol consists in doping a sample with a small amount of paramagnetic species, t ...

Core-Shell Structure of Organic Crystalline Nanoparticles Determined by Relayed Dynamic Nuclear Polarization NMR

David Lyndon Emsley, Arthur César Pinon, Jasmine Viger-Gravel

The structure of crystalline nanoparticles (CNPs) is determined using dynamic nuclear polarization (DNP) enhanced NMR spectroscopy experiments. The CNPs are composed of a crystalline core containing an active pharmaceutical ingredient (compound P), coated ...

Dynamic Nuclear Polarization of Long-Lived Nuclear Spin States in Methyl Groups

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Basile Vuichoud, Daniele Mammoli, Arthur César Pinon, Gabriele Stevanato

We have induced hyperpolarized long-lived states in compounds containing C-13-bearing methyl groups by dynamic nuclear polarization (DNP) at cryogenic temperatures, followed by dissolution with a warm solvent. The hyper polarized methyl long-lived states g ...

Microwave-gated dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Arthur César Pinon, Xiao Ji, Mathieu Baudin

Dissolution dynamic nuclear polarization (D-DNP) has become a method of choice to enhance signals in nuclear magnetic resonance (NMR). Recently, we have proposed to combine cross-polarization (CP) with D-DNP to provide high polarization P(C-13) in short bu ...
