Simple and cost-effective cross-polarization experiments under dissolution-dynamic nuclear polarization conditions with a 3D-printed 1H-13C background-free radiofrequency coil

Publication Type:Academic Journal

Source(s):Journal of Magnetic Resonance Open, Vol 10, Iss , Pp 100033- (2022)

Abstract:The low sensitivity of conventional nuclear magnetic resonance experiments can be overcome, in suitable cases, by employing hyperpolarization methodologies. One such technique, dissolution-dynamic nuclear polarization, provides a robust means of strong...

Solid-state 1H spin polarimetry by 13CH3 nuclear magnetic resonance

Publication Type:Academic Journal

Source(s):Magnetic Resonance, Vol 2, Pp 643-652 (2021)

Abstract:Dissolution dynamic nuclear polarization is used to prepare nuclear spin polarizations approaching unity. At present, 1H polarization quantification in the solid state remains fastidious due to the requirement of measuring thermal equilibrium signals. ...

An automated system for fast transfer and injection of hyperpolarized solutions

Publication Type:Academic Journal

Source(s):Journal of Magnetic Resonance Open, Vol 8, Iss , Pp 100017- (2021)

Abstract:Dissolution dynamic nuclear polarization (dDNP) has become a hyperpolarization method of choice for enhancing nuclear magnetic resonance (NMR) signals. Nuclear spins are polarized in solid frozen samples (in a so-called polarizer) that are subsequently...

Boosting dissolution-dynamic nuclear polarization by multiple-step dipolar order mediated 1H→13C cross-polarization

Publication Type:Academic Journal

Source(s):Journal of Magnetic Resonance Open, Vol 8, Iss , Pp 100018- (2021)

Abstract:Dissolution-dynamic nuclear polarization can be boosted by employing multiple-contact cross-polarization techniques to transfer polarization from 1H to 13C spins. The method is efficient and significantly reduces polarization build-up times, however, i...

Dipolar order mediated 1H → 13C cross-polarization for dissolution-dynamic nuclear polarization

Publication Type:Academic Journal

Source(s):Magnetic Resonance, Vol 1, Pp 89-96 (2020)

Abstract:Magnetic resonance imaging and spectroscopy often suffer from a low intrinsic sensitivity, which can in some cases be circumvented by the use of hyperpolarization techniques. Dissolution-dynamic nuclear polarization offers a way of hyperpolarizing 13C ...

Surgical site infection after gastrointestinal surgery in children: an international, multicentre, prospective cohort study

Publication Type:Academic Journal

Source(s):BMJ Global Health, Vol 5, Iss 12 (2020)

Abstract:Introduction Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study...

Transportable hyperpolarized metabolites

Publication Type:Academic Journal

Source(s):Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)

Abstract:MRI imaging can be significantly enhanced by injecting highly magnetized chemical agents, but the short magnetization lifetime requires processing at the point of use. Here, the authors demonstrate a method that could extend the lifetime from seconds t...

Dynamic Nuclear Polarization and Other Magnetic Ideas at EPFL

Publication Type:Academic Journal

Source(s):CHIMIA, Vol 66, Iss 10 (2012)

Abstract:Although nuclear magnetic resonance (NMR) can provide a wealth of information, it often suffers from a lack of sensitivity. Dynamic Nuclear Polarization (DNP) provides a way to increase the polarization and hence the signal intensities in NMR spectra b...
