Homogeneous Catalysis for
Unreactive Bond Activation
This book offers a comprehensive overview of different catalytic reactions applied to the activation of chemical bonds.
In contrast to the reactive alkali metals (1 st main group or 1 st group of the
periodic system), the coinage metals are noble (unreactive). Their first ionization
potentials are much higher than those of the alkali metals from the same period,
and ...

Thus relatively unreactive metals such as Au, Pd, and Pt that form eutectics with
Zn display rectifying l-V characteristics and increases in ~2.1 eV defect emission,

Footprints in the Soil: People and Ideas in Soil History
Restricting and thereby delaying drainage lessened losses of molybdate-
unreactive phosphate, probably because suspended material carrying it was
allowed to settle. Increasing the spacing between mole channels from 2 m to 4 m
increased ...

Reactive Halogen Compounds in the Atmosphere
If the lifetime is less than about one year, the gases are considered to be "
reactive"; if it is between 1-10 years, the gases are "moderately reactive"; and if
the lifetimes are longer, the gases are "unreactive" and are not removed in the
lower ...
