High-Field C-13 Dynamic Nuclear Polarization in Nanodiamond
Stefano Alberti, Jean-Philippe Ansermet, Jérémy Genoud, Serguei Sekatski, Murari Soundararajan, Dongyoung Yoon
Hyperpolarization in diamond via dynamic nuclear polarization (DNP) has attracted a lot of interest for various applications as diamond exhibits extremely long C-13 spin relaxation times and has endogenous polarizing agents in the form of crystalline defec ...
2019BDPA-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, Moreno Lelli, Arthur César Pinon, 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 ...
AMER CHEMICAL SOC2018Development and characterisation of gyrotron-based Dynamic Nuclear Polarisation and Electron Paramagnetic Resonance spectroscopy at 9 Tesla
The Dynamic nuclear polarisation (DNP) enhanced nuclear magnetic resonance (NMR) results presented in this thesis demonstrate the functionality of a tunable and switchable gyrotron operating at 260 GHz with a 9 T spectrometer. This gyrotron was designed at ...
EPFL2018Extending the lifetime of hyperpolarisation
In nuclear magnetic resonance (NMR), one of the most serious inherent challenges is the low sensibility of nuclei. In order to enhance the signal of NMR experiments, the technique of dynamic nuclear hyperpolarisation (DNP) was introduced in the 1950s, lead ...
EPFL2017Method for nuclear magnetic resonance (NMR) spectroscopy measurements using long-lived coherences (LLC)
Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja
A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...
2013Decoupling of Magnetic Resonance Signals in Time and Frequency Domain
Nuclear magnetic resonance (NMR) was discovered in the first half of the 20th century. Today, neither analytical chemistry without NMR spectroscopy nor medical diagnostics without magnetic resonance imaging (MRI) could be imagined. A magnetic resonance sig ...
EPFL2013Over-moded resonant cavity for magnetic resonance based on a photonic band gap stucture
Emile Jacques de Rijk, Alessandro Macor
The present invention relates to a probe for multiple irradiation magnetic resonance techniques like, for instance, dynamic nuclear polarization (DNP) or ENDOR. The probe comprises an overmoded resonant cavity based on a Photonic Band Gap (PBG) structure f ...
2013Dynamic Studies through Control of Relaxation in NMR Spectroscopy
In numerous biological processes that constitute the base of living organisms, protein function is fundamentally related to internal dynamics occurring on μs-ms time scales that can give rise to chemical exchange contributions to relaxation. In a heteronuc ...
EPFL2013Structure and backbone dynamics of a microcrystalline metalloprotein by solid-state NMR
We introduce a new approach to improve structural and dynamical determination of large metalloproteins using solid-state nuclear magnetic resonance (NMR) with H-1 detection under ultrafast magic angle spinning (MAS). The approach is based on the rapid and ...
NATL ACAD SCIENCES2012Micro-fabricated alkali vapor cells sealed at low temperatures with thin-film metallic bonding
Nico de Rooij, Danick Briand, Yves Pétremand
We report on the characterization of micro-fabricated alkali vapor cells, sealed by low-temperature thin-film metallic bonding. The low sealing temperatures ≤ 140°C are of high interest in view of future micro-fabricated cells using anti-relaxation wall co ...
