Spin-dependent electrocatalysis.
Chen Z, Li X, Ma H, Zhang Y, Peng J, Ma T, Cheng Z, Gracia J, Sun Y, Xu ZJ. Chen Z, et al. Natl Sci Rev. 2024 Sep 5;11(9):nwae314. doi: 10.1093/nsr/nwae314. eCollection 2024 Sep. Natl Sci Rev. 2024. PMID: 39363911 Free PMC article. Review.
Recent findings reveal that the efficiency of some electrocatalytic reactions is spin-dependent, with spin configuration dictating performance. Consequently, understanding the spin's role and controlling it in electrocatalysts is important. This review succinctly ou …

Velocity-selective excitation: Principles and applications.
Zun Z, Shin T. Zun Z, et al. NMR Biomed. 2023 Feb;36(2):e4820. doi: 10.1002/nbm.4820. Epub 2022 Sep 9. NMR Biomed. 2023. PMID: 35994473 Free PMC article. Review.
Velocity-selective (VS) excitation is a relatively new type of excitation that can be useful for generating image contrast based on spin's motion. This review aims to explain the principles of VS excitation and their utilization for clinical applications. We first r …

Ultra-low temperature MAS-DNP.
Lee D, Bouleau E, Saint-Bonnet P, Hediger S, De Paëpe G. Lee D, et al. J Magn Reson. 2016 Mar;264:116-124. doi: 10.1016/j.jmr.2015.12.010. J Magn Reson. 2016. PMID: 26920837
Hence, high-field dynamic nuclear polarization (DNP) making use of high-frequency, high-power microwave irradiation of electron spins has become very promising in combination with magic angle sample spinning (MAS) solid-state NMR experiments. This is because it lead …

Cross polarization from spins I=12 to spins S=1 in nuclear magnetic resonance with magic angle sample spinning.
Gopalakrishnan K, Bodenhausen G. Gopalakrishnan K, et al. J Chem Phys. 2006 May 21;124(19):194311. doi: 10.1063/1.2197827. J Chem Phys. 2006. PMID: 16729818
The theory is extended to describe cross-polarization between spins S=1 and I=12 under MAS. There are four distinct Hartmann-Hahn matching conditions that correspond to four zero-quantum matching conditions, all of which are shifted and broadened compared to their spin …

High spin axion insulator.
Li S, Gong M, Li YH, Jiang H, Xie XC. Li S, et al. Nat Commun. 2024 May 18;15(1):4250. doi: 10.1038/s41467-024-48542-4. Nat Commun. 2024. PMID: 38762497 Free PMC article.
Here, we propose a high-spin axion insulator (HSAI) defined in large spin-s representation, which maintains the same inherent symmetry but possesses a notable axion field theta = (s + 1/2)(2)pi. ...

Heisenberg spin chain with random-sign couplings.
Fava M, Jacobsen JL, Nahum A. Fava M, et al. Proc Natl Acad Sci U S A. 2024 Sep 3;121(36):e2401292121. doi: 10.1073/pnas.2401292121. Epub 2024 Aug 29. Proc Natl Acad Sci U S A. 2024. PMID: 39207732 Free PMC article.
We find that, at least for sufficiently large spin S, the ground state has "spin glass" order. The spin waves on top of this state have the dynamical exponent [Formula: see text], intermediate between the values z = 1 of the antiferromagnet and z = 2 of the ferromag …

Spectroscopic characterization of cytochrome P450 Compound I.
Jung C, de Vries S, Schünemann V. Jung C, et al. Arch Biochem Biophys. 2011 Mar 1;507(1):44-55. doi: 10.1016/j.abb.2010.12.029. Epub 2010 Dec 30. Arch Biochem Biophys. 2011. PMID: 21195047 Review.
Very recently, however, Rittle and Green [9] have shown that Cpd I of CYP119, the thermophilic P450 from Sulfolobus acidocaldarius, is univocally a Fe(IV)O-porphyrin radical with the ferryl iron spin (S=1) antiferromagnetically coupled to the porphyrin radical sp …

A test for the number of coupled spins I = 1/2 in magic-angle-spinning solids: zero-quantum recoupling of multiple-quantum coherences.
Hughes CE, Schmedt auf der Günne J, Levitt MH. Hughes CE, et al. Chemphyschem. 2003 Apr 14;4(5):457-65. doi: 10.1002/cphc.200200470. Chemphyschem. 2003. PMID: 12785259
Current methodologies for estimating the number of coupled spins I = 1/2 in solids are based upon the maximum multiple-quantum order that can be observed. This strategy establishes a clear lower bound on the number of coupled spins I = 1/2. However, it is difficult …
