Introduction General Information on Technetium

In March 1869, the Russian scientist Dmitri Mendeleev presented to the Russian Society of Physics and Chemistry, the idea of the so-called periodic table. He proposed that chemical elements can be

Exploring EPR Parameters of 99Tc Complexes for Designing New MRI Probes: Coordination Environment, Solvent, and Thermal Effects on the Spectroscopic Properties

We have evaluated the solvent and thermal effects on spectroscopic parameters of 99Tc complexes coordinated to explicit water molecules. Molecular dynamics simulations were performed followed by

Explaining stability of transition metal carbides – and why TcC does not exist

We analyze the formation of transition metal (TM) carbides, as determined by the strength of TM–TM and TM–C bonds, as well as lattice distortions induced by C interstitials. With increasing filling

99Tc NMR as a promising technique for structural investigation of biomolecules: theoretical studies on the solvent and thermal effects of phenylbenzothiazole complex

The results highlight that the 99Tc NMR spectroscopy can be a promising technique for structural investigation of biomolecules, at the molecular level, in different environments.

Beyond Electrons in a Box: Nanoparticles of Silver, Platinum and Rhodium

This chapter presents a review of NMR in small particles of three elemental metals: the "odd electron" Ag and Rh, and the "even electron" Pt. These experiments on elements close to each other in the

Technetium: behaviour during reprocessing of spent nuclear fuel and in environmental objects

The review surveys main chemical properties of technetium, methods of its isolation and determination and its behaviour during reprocessing of spent nuclear fuel and in environmental objects. Methods

195Pt NMR of polymer-protected Pt/Pd bimetallic catalysts

Colloids of Pt, Pt0.8Pd0.2, and Pt0.2Pd0.8 particles of approximately 2.5 nm diameter with poly (N-vinyl-2-pyrrolidone) as protecting agent were dried, and the 195Pt NMR spectrum and nuclear

NMR of platinum catalysts: Double NMR of chemisorbed carbon monoxide and a model for the platinum NMR line shape.

Analysis of the {sup 195}Pt spin-lattice relaxation indicates that the small surface Knight shift results from cancellation of 6s and 5d core-polarization contributions as was found theoretically by Weinert and Freeman for clean Pt surfaces.
