Marie Ramirez Cohen et al.
Electron spectral diffusion (eSD) plays an important role in solid-state, static dynamic nuclear polarization (DNP) with polarizers that have inhomogeneously broadened EPR spectra, such as nitroxide radicals. It affects the electron spin po...
Transferring principles of solid-state and Laplace NMR to the field of in vivo brain MRI [0.03%]

João P de Almeida Martins et al.
Magnetic resonance imaging (MRI) is the primary method for noninvasive investigations of the human brain in health, disease, and development but yields data that are difficult to interpret whenever the millimeter-scale voxels contain multip...
Electroplated waveguides to enhance DNP and EPR spectra of silicon and diamond particles [0.03%]
电镀波导增强硅和金刚石颗粒的DNP和EPR光谱

Electroplating the waveguide of a 7 T polarizer in a simple innovative way increased microwave power delivered to the sample by 3.1 dB. Silicon particles, while interesting for hyperpolarized MRI applications, are challenging to polarize du...
Site-selective generation of lanthanoid binding sites on proteins using 4-fluoro-2,6-dicyanopyridine [0.03%]
使用4-氟-2,6-二氰基吡啶在蛋白质上位点选择性地生成镧系金属配位位点

Sreelakshmi Mekkattu Tharayil et al.
The paramagnetism of a lanthanoid tag site-specifically installed on a protein provides a rich source of structural information accessible by nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy. Here we r...
Fine optimization of a dissolution dynamic nuclear polarization experimental setting for 13C NMR of metabolic samples [0.03%]
代谢样品13C NMR动态核极化溶解实验的精细优化

Arnab Dey et al.
NMR-based analysis of metabolite mixtures provides crucial information on biological systems but mostly relies on 1D 1H experiments for maximizing sensitivity. However, strong peak overlap of 1H spectra often is a limitation for the analysi...
Reverse dynamic nuclear polarisation for indirect detection of nuclear spins close to unpaired electrons [0.03%]

Since the dawn of quantum mechanics, ways to visualize spins and their interactions have attracted the attention of researchers and philosophers of science. In this work we present a generalized measurement-based 3D-visualization approach f...
Insight into the structure of black coatings of ancient Egyptian mummies by advanced electron magnetic resonance of vanadyl complexes [0.03%]
