Molecules and Metals

Nuclear fusion in muonic molecules and in deuterated metals

Study of the fusion reactions between hydrogen isotopes in muonic molecules is the first example of the accurate accounting of the nucleus charge screening by a muon in the fusion process. At LUNA installation the measurements of astrophysical reaction cross sections were extended down to collision energies of a few keV. The screening by atomic electrons of the target became substantial. The po...

Activation of Atmospheric Small Molecules by Transition Metals

Molecules containing rare-earth atoms solely bonded by transition metals.

Although metal-metal bonding is important in the chemistry of both solid-state intermetallic compounds and molecular species, the study of this bonding is limited by the compounds available and it is rarely possible to identify connections between these two areas. In this study, molecular intermetalloids [Ln(ReCp(2))(3)] (Ln = Sm, Lu and La) have been synthesized that contain lanthanoid metals ...

Metals and Non-metals

Ductile: Substances that can be drawn into thin wires are called ductile. For example, most of the metals are ductile. Question 2: Why is sodium kept immersed in kerosene oil? Answer: Sodium and potassium are very reactive metals and and combine explosively with air as well as water. Hence, they catch fire if kept in open. Therefore, to prevent accidental fires and accidents, sodium is stored i...
