As a result, simple rules for the alloying behaviour of transition metals are formulated which have an accuracy between 96 and 100%; the electronegativity concept is shown to apply also for hydrogen in metals. The relation between the charge transferred per atom, ΔZ a, and the difference in...
The enhanced response of alloy may be attributed to high hole carrier concentration through electronic sensitization mechanism and fast charge transfer process. In the above-presented research, the electrode material of WSe2 based gas sensor was made of rigid metals like Au, Pt, Ti, Pd, etc. ...
In a few instances O-transfer to a substrate other than CO/sub 2/ has been observed such as to oxophilic metals, isocyanides, or phosphines, the latter catalytically. In an effort to expand the scope of these reactions and to overcome their thermodynamic limitations, the authors are seeking...
Transition metals: Taking charge
Single-ligand complexes of first series transition metals with ammonia, water, hydroxide, and fluoride, many known in the gas phase, have been studied in calculations covering the 20 mono- and divalent cations and some very unusual binding patterns have been found. Binding energies and binding geo...

A functional integral approach to the one-dimensional electron-phonon problem The interplay between lattice and electronic fluctuations in one-dimensional electron-phonon systems is analyzed by a path integral approach in terms of bo... C Bourbonnais,LG Caron - 《Synthetic Metals》 被引量: 12发表:...
This uniform treatment suggests that effective charges for the transition metals are generally less than one, and that their valence is lower than the usual Pauling maximum of six. In addition, it was noted that the boron PAV volume... FL Carter - 《Journal of the Less Common Metals》 被...
Precise control from the bottom-up for realizing tunable functionality is of utmost importance to facilitate the development of molecular electronic devices. Until now, however, manipulating charge carriers over single-molecule scale remains intractable.
We foundthat the valence charge of transition metals dramatically influencesthe reaction pathways. Catalytic reactions involving lower-oxidation-statetransition metals (M I /M III , M = Co and Rh) generallyfavor a [3 + 2] cyclization pathway, whereas those involving higheroxidation states (M III...
