Empirically it is known that moderate selectivity of silver can be greatly enhanced with cesium and chlorine dopants, whereas a mechanistic understanding of the underlying reason remains elusive. In this work, we present a first-principles explanation of the dipole effect on reaction selectivity, ...
Alkali Metals:Alkali metals are elements of group 1.They are called alkali metals because the hydroxides they form on reaction with water, is highly alkaline in nature. The elements listed below constitute group 1 elements and are collectively considered as alkali metals. ...

The combustion behavior, gaseous emissions, and alkali metals released during the combustion of several biomass/coal blends were investigated using a direct sampling, molecular beam mass spectrometer (MBMS) system in conjunction with a high-temperature alumina-tube flow reactor. Pittsburgh No. 8 and ...

Alkali metals are the elements of group 1 of the periodic table that when reacts with water, produces an alkaline solution, along with the release of hydrogen gas. Alkali metals include lithium, sodium, potassium, rubidium, and cesium.
