Heterodisulfide reductase (Hdr) from methanogenic archea is an iron-sulfur protein that catalyzes the reversible two-electron reduction of the mixed disulfide CoM-S-S-CoB to the thiol coenzymes,… Expand
Purification and optical spectroscopy of N@C60
Using multi-step high performance liquid chromatography (HPLC) it was possible to prepare a chromatographically pure sample of N@C60. Invoking EPR spectroscopy of solid samples prepared after each… Expand
Atomic Nitrogen Encapsulated in Fullerenes: Effects of Cage Variations
The synthesis and EPR spectroscopic investigations of a family of six endohedral fullerenes, namely, N@C60 (1), N@C61(COOC2H5)2 (2), N@C66(COOC2H5)12 (3), N@C66(COOC2D5)12 (4), N@C61(COOC2D5)2 (5),… Expand
Potential of High-Frequency EPR for Investigation of Supported Vanadium Oxide Catalysts
Supported vanadium oxide catalysts were studied by high-frequency EPR for determination of the paramagnetic vanadium oxidation states vanadium(IV) and vanadium(III). TiO 2 -, γ-Al 2 O 3 -, and SiO 2… Expand

Single-wall carbon nanotubes (SWNT) prepared by the "super growth" method developed recently exhibit electron paramagnetic resonance (EPR) signals, which can be attributed to itinerant spins. EPR… Expand
EPR investigation of atoms in chemical traps
Abstract By performing high-resolution EPR and ENDOR experiments on nitrogen atoms encapsulated in C 60 , the capability of the quartet spin system to sense small local fields at the site of the atom… Expand
Electron paramagnetic resonance study of atomic phosphorus encapsulated in fullerene
Well resolved EPR spectra of P@C60 in solution have been recorded, proving that the encased phosphorus atoms are in their quartet spin ground state. The isotropic hyperfine interaction is increased… Expand
EPR characterization of catalyst-free SWNT and N@C60-based peapods
Single Wall Carbon Nanotubes (SWNT) produced by "Super-Growth" CVD technique show no evidence for non-carbon impurities. At X-Band frequencies an EPR signal from conduction electrons is observed at… Expand
