Finally, the formation of mono-, di- and polynuclear complexes of the transition metals coordinated to the bis-terpyridine acceptor ligand (tppz) was achieved and the results were found to be dependent on the solvent and metal ion identity (Fe(II), Co(II), Ni(II)). The tppz complexes ...
Ternary rare earth silicides of the LnMxSi2−x system were investigated for the composition range between LnSi2 and LnM2. The rare earth elements studied were Pr, Nd, Dy, and Er and the transition metals were Fe, Co, Ni, and Ag. The main structures found were of the ThSi2 and AlB...
In the globular range of metal transfer the current is too low to form the necessary jet and pinch forces for detachment of the droplet. As the current is increased the transition from globular to projected spray occurs wherein the droplets detach from the tip of the electrode when they are ...

Their complexation by transition metals leads to electrophilic (Fischer) or nucleophilic (Schrock) complexes with very different reactivities. Their role in the metathesis of alkenes is highlighted. A similar pres-entation of metal carbynes and their role in the metathesis of alkynes completes this ...

The Unified Numbering System for Metals and Alloys (UNS) assigns a unique identifier to each metal type, consisting of a letter followed by five digits. This number specifies the chemical composition of the metal or alloy rather than its mechanical properties. The first three digits of a UNS ...
transition metals and to the left of the metalloids, reactivenon-metals, and noble gases. Periods in the periodic table refer to the rows, and base metals are found in periods three through six. Groups in the periodic table refer to the columns, and base metals are found in groups 8-15...
