The Behavior of Lewis Number in Finned Tube Cooling Coils under Highly Moist Inlet Air Conditions
International Journal of Technology, 2016 The objective of this research was to study the effects of highly moist inlet air conditions such as temperature, relative humidity, and frontal air velocity on the value of the Lewis number (Le) in the cooling and dehumidifying process of air.

Cation affinity numbers of Lewis bases [PDF]
Beilstein Journal of Organic Chemistry, 2012 Using selected theoretical methods the affinity of a large range of Lewis bases towards model cations has been quantified. The range of model cations includes the methyl cation as the smallest carbon-centered electrophile, the benzhydryl and trityl cations as models for electrophilic substrates encountered in Lewis base-catalyzed synthetic procedures ...
