Non-hydrogenative para-hydrogen-induced polarization (PHIP) is a fast, efficient and relatively inexpensive approach to enhance nuclear magnetic resonance (NMR) signals of small molecules in solution. The efficiency of this technique depend...
Exchange interaction in short-lived flavine adenine dinucleotide biradical in aqueous solution revisited by CIDNP (chemically induced dynamic nuclear polarization) and nuclear magnetic relaxation dispersion [0.03%]
化学诱导动态核极化和核磁弛豫散射在含水溶液中短暂存生的烟酰胺腺嘌呤二核苷酸自由基交换作用中的重新应用研究

Ivan V Zhukov et al.
Flavin adenine dinucleotide (FAD) is an important cofactor in many light-sensitive enzymes. The role of the adenine moiety of FAD in light-induced electron transfer was obscured, because it involves an adenine radical, which is short-lived ...
Structural polymorphism and substrate promiscuity of a ribosome-associated molecular chaperone [0.03%]
与核糖体相关分子伴侣的结构多态性及底物泛素性
Chih-Ting Huang,Yei-Chen Lai,Szu-Yun Chen et al.
Chih-Ting Huang et al.
Trigger factor (TF) is a highly conserved multi-domain molecular chaperone that exerts its chaperone activity at the ribosomal tunnel exit from which newly synthesized nascent chains emerge. TF also displays promiscuous substrate binding fo...
The long-standing relationship between paramagnetic NMR and iron-sulfur proteins: the mitoNEET example. An old method for new stories or the other way around? [0.03%]
.paramagnetic核磁共振与铁硫蛋白的长期联系：mitoNEET蛋白为例。旧方法的新故事，还是新方法的旧故事？
Francesca Camponeschi,Angelo Gallo,Mario Piccioli et al.
Francesca Camponeschi et al.
Paramagnetic NMR spectroscopy and iron-sulfur (Fe-S) proteins have maintained a synergic relationship for decades. Indeed, the hyperfine shifts with their temperature dependencies and the relaxation rates of nuclei of cluster-bound residues...
Pd-based bimetallic catalysts for parahydrogen-induced polarization in heterogeneous hydrogenations [0.03%]

Change is inherent to time being transient. With the NMR-MOUSE (MObile Universal Surface Explorer) having matured into an established NMR tool for nondestructive testing of materials, this forward-looking retrospective assesses the challeng...
Residual dipolar line width in magic-angle spinning proton solid-state NMR [0.03%]
固体状态NMR中剩余各向异性引起的一维谱线展宽研究
Matías Chávez,Thomas Wiegand,Alexander A Malär et al.
Matías Chávez et al.
Magic-angle spinning is routinely used to average anisotropic interactions in solid-state nuclear magnetic resonance (NMR). Due to the fact that the homonuclear dipolar Hamiltonian of a strongly coupled spin system does not commute with its...
Open-source, partially 3D-printed, high-pressure (50-bar) liquid-nitrogen-cooled parahydrogen generator [0.03%]
开源且部分采用3D打印的高压（50巴）液氮冷却para氢气发生器

The signal of magnetic resonance imaging (MRI) can be enhanced by several orders of magnitude using hyperpolarization. In comparison to a broadly used dynamic nuclear polarization (DNP) technique that is already used in clinical trials, the...
Non-classical disproportionation revealed by photo-chemically induced dynamic nuclear polarization NMR [0.03%]
光化学动态核极化NMR揭示的非经典歧化反应

Jakob Wörner et al.
Photo-chemically induced dynamic nuclear polarization (photo-CIDNP) was used to observe the light-induced disproportionation reaction of 6,7,8-trimethyllumazine starting out from its triplet state to generate a pair of radicals comprising a...
