The Application of Hyperfine Interactions in Biology
نویسندگان
چکیده
-The application of Mossbauer spectra to the study of the state of iron atoms in biological ~nolecules is described. The chetiiical shift when suitably calibrated enables the oxidation state of the iron to be determined. The magnetic hyperfine coupling is even more sensitive to the state of the iron and for iron-sulphur proteins provides direct evidence that groups of iron atoms are strongly coupled together antiferrornagtietically.

Presenting a model for theoretical study of baryon masses, either in relativistic or nonrelativistic area, has always been of great importance and several suggestions have been proposed. On the other hand, taking into account the effects of hyperfine interactions leads to interesting results. In the present work, we first introduce the hyperfine interaction and the quark potential corresponding...

The hyperfine interactions at the uranium site in the antiferromagnetic USb2 compound were calculated within the density functional theory (DFT) employing the augmented plane wave plus local orbital (APW+lo) method. We investigated the dependence of the nuclear quadruple interactions on the magnetic structure in USb2 compound. The investigation were performed applying the so called “band corr...

Tissue engineering is based on three main factors including scaffolds, cells and growth factors. Natural scaffolds derived from decellularized tissues and organs have been successfully used in tissue engineering. Decellularization studies have shown that natural scaffolds which maintaine their main structure and properties could be a suitable tool for studying cellular behaviors and preparation...
