Cloud Condensation Nuclei properties of model and atmospheric HULIS
Humic like substances (HULIS) have been identified as a major fraction of the organic component of atmospheric aerosols. These large multifunctional compounds of both primary and secondary sources are surface active and water soluble. Hence, it is expected that they could affect activation of organic aerosols into cloud droplets. We have compared the activation of aerosols containing atmospheri...
متن کاملAlpha-particle condensation in nuclei
A round up of the present status of the conjecture that nα nuclei form an αparticle condensate in excited states close to the nα threshold is given. Experiments which could demonstrate the condensate character are proposed. Possible lines of further theoretical developments are discussed. In this article we want to report on the present status of our recent conjecture [1] that at least light nα...

متن کاملCondensation: Passenger Not Driver in Atmospheric Thermodynamics
The second law of thermodynamics states that processes yielding work or at least capable of yielding work are thermodynamically spontaneous, and that those costing work are thermodynamically nonspontaneous. Whether a process yields or costs heat is irrelevant. Condensation of water vapor yields work and hence is thermodynamically spontaneous only in a supersaturated atmosphere; in an unsaturate...
