The chemical shift and relaxation time pattern of the hyperfine-shifted signals is very similar to other oxidized Fe 4 S 4 ferredoxins. A tentative sequence-specific assignment of these resonances according to a general pattern of chemical shift of cysteine protons versus sequence position of ...
NMR spectrum. NMR spectrum of the purified melanin pigment synthesized by Streptomyces glaucescens strain NEAE-H (Fig. 7B) shows resonances between 8.0 and 6.0 ppm and between 0.813 and 4.504 ppm. Resonances between 8.0 and 6.0 ppm in NMR spectra are assigned to aromatic ...
High-resolution 1H MAS NMR spectra of thin films of FAPbI3 passivated with DMPESI are shown in Fig. 2f–h. Whereas the aromatic signals of DMPESI (6–8.5 ppm) overlap with those of FA in Fig. 2f, the spectrum (0–5 ppm) contains signals originating from the aliphatic part of ...
Any of such techniques may be employed per se or in combination with one or more of the other two to generate a control signals upon detecting the presence of a particular organism in the fluid scanned, which control signal may be employed to pulse an auxilliary laser or to cause the ...

Typically, in the case of 2a, substantial downfield shifts due to the introduced boryl group were observed for two singlet signals, meso-H4 (δ ) 11.01) and β-H5 (δ ) 9.68), while the 1H NMR spectrum of 1a exhibits meso-H1, β-H2, and β-H3 at 10.32, 9.41, and 9.13 ppm, ...
NMRMicrostructureIn order to optimize hydrogen storage properties of bcc Ti-V-Cr alloys it was found that alloying with a few 4 at% of Zr7Ni10 results in acceleration the hydrogen sorption kinetics in the composite material. The novel intergranular phase plays a role of gate for hydrogen, ...
